Calculate how many cubes of timber you need per house. Calculation of a beam for a bath - the main features of this process

Units of measurement are millimeters. Beam width

Information on the purpose of the calculator

Online calculator for profiled and glued beams is designed to calculate the quantity and volume of lumber for the construction of houses, baths and other buildings. The amount of interventional insulation, dowels, crowns, cost and anti-corrosion impregnation is automatically calculated according to the average value. For more accurate calculations, be sure to contact the specialists in your area.

In order to understand the advantages and disadvantages of profiled lumber compared to glued lumber, one should start with the basic concepts of the production of both.

Profiled timber is made from coniferous trees. In most cases, it has standard cross-sectional dimensions:

• 100x100 mm is best suited for the construction of a bathhouse or a summer country house
• 150x150 mm suitable for a good home
• 200x200 mm for the construction of large wooden houses or cottages

If desired, you can individually order a bar of a different section. The appearance of the beam can be both with a straight front side and with a D-shaped one. A log of the desired thickness is processed on planing and milling machines, after which it is polished from the right sides. High-quality grinding is usually subjected to that side of the beam, which will be located inside the future house and may not require further finishing. For convenience and reliability of the installation of the log house and for protection from cold and moisture, the profile most often comes with 1 or 2 spikes for light construction or a “comb” for a residential building. The finished log house must shrink for further completion of construction, usually this period is about 1 year. To reduce this period to several months, you can dry the timber in advance in special chambers.

For the production of glued beams, the log is sawn into boards, they are also called "lamellas". The boards are stretched and laid in a drying chamber, where, in the process of drying in a soft mode, a material with a moisture content of about 10% is obtained. Then the boards are again planed to the desired dimensions, sorted, and then glued into a beam using a hydraulic press. For gluing, special waterproof adhesive compositions are used. In order to give the glued beam resistance to decay and significantly increase its strength, the boards are stacked in a special way - each is laid opposite to the cross section of the neighboring fibers.

In profiled wood, during the production process, the outer, more durable part of the wood is cut off to give the desired shape. Due to the previously described method of laying boards and gluing them on a hydraulic press, glued laminated timber is more durable. As many people know, larch is the most durable and resistant to decay, but also the most expensive in price among conifers. The manufacture of profiled timber from it significantly increases the cost of construction. In the production of glued beams, it is possible to lay an external larch lamella before gluing, which slightly affects the price increase.

When comparing the moisture content of the material and the shrinkage time, it has already been noted that glued laminated timber has a moisture content of about 10% and, accordingly, a short shrinkage period, which makes it possible to reduce the construction time of a house. Profiled timber has a natural moisture content of wood, and even drying it can reduce the moisture content to only 20%, so shrinkage is indispensable. Comparing the shrinkage time, we must not forget the fact that the solid material, due to its greater massiveness, is practically not subject to cracking, and on the glued beam there is a possibility of small cracks.

And because of the technological features of manufacturing, each type of timber can have different overall dimensions. The profile usually has a length of up to 6 meters, and a section of 100x100, 150x150 and 200x200 mm. Making a bar of a different section size (for example, with a step every 10 mm) can increase the amount of waste, which cannot but affect the price. For glued beams, the length can reach 12 meters, and the cross section is usually made from 80 to 280 mm.

But taking into account only the cost of the finished log house, do not forget that finishing for facades when using glued laminated timber may not be required, and you can compare them at a price with a stretch. Everything will depend on the material chosen for finishing the house, its quantity and cost.

About environmental friendliness, profiled timber is not just a favorite, but rather a champion, retaining all the useful properties of such an excellent material as natural wood. For processing, only special mixtures may be needed to protect against fire and decay, which the owner of the house can choose. In the production of glued beams, adhesive compositions can be used, which are divided into several groups according to the degree of danger, and it is not a fact that the manufacturer did not decide to save on the cost of glue.

In conclusion, we can say that each of the 2 types of timber considered has its undoubted advantages with a small number of disadvantages. And only the owner can decide what material to build a house from in order to live in it further.

The log house construction calculator is simple and intuitive to use. The introduction of indicators is no different from the above process. You can not only calculate the timber for the house, but also calculate the approximate cost of the required materials.

Calculation of the quantity and cost of timber

The calculation of timber for the construction of a house, bathhouse, shed or any other structure is a separate function in the calculator. Using it, you can get the following results:

1. The total volume of all parts of the timber. The approximate amount of the specified lumber in cubic meters.
2. Area of ​​all walls. According to the results, it is identical to the area of ​​\u200b\u200binsulation (if any). The outer side of the walls is taken into account.
3. Total weight of material. Total weight in kilograms. The weight of the heater is not taken into account.
4. Total number of crowns. In other words, the calculation of the number of rows of timber per wall, based on the dimensions of the material and how high the walls of the building are. Fronts are not taken into account.
5. The total amount of insulation material. Equal to the total area of ​​\u200b\u200bthe timber for construction.
6. The amount of anti-corrosion impregnation. The number of all impregnation layers is taken into account: from the inner and outer sides of the wall.
7. Number and diameter of dowels. It is calculated taking into account the step length - 1.5 m. It is applied to lightly loaded parts of a timber building. This calculation is best done in consultation with experts in the field of calculating the amount of building materials needed for the construction.
. This point cannot be ignored when choosing materials for the foundation, because. thanks to this parameter you will determine how strong it will be. The load of the roof and ceilings is not included in this characteristic.
8. Estimated degree of shrinkage from timber (4%). Approximate shrinkage force at 20% humidity.

What timber to use for construction?

Profiled and glued beams have their own advantages and disadvantages, which lie in the features of their manufacture. So, profiled timber is made from softwood, most often it is made with standard section sizes (100 × 100, 150 × 150, 200 × 200). The larger the cross section of the beam, the more stable the structure that is built from it will be. Therefore, for the construction of houses and cottages, a beam of 200 × 200 is most often used.

The "secret" of glued laminated timber is hidden in its name: it consists of "lamellas" glued together - logs sawn into boards. The slats are preliminarily dried in a special apparatus, and then planed and prepared for gluing. After that, they are interconnected with waterproof glue.

If we evaluate these two types of timber with each other, then at least glued wins in strength. If you do not know what material to choose for the construction of a structure, consult an expert.

The online calculator will help not only make a calculation timber on the house in a matter of seconds, but also determine the approximate cost of lumber. Just enter the data in the form and find out the result in a moment. Try an online calculator at least once and you will regret not knowing about it sooner.

Calculation of a beam for a bath - the main features of this process

If you decide to build a bathhouse on your backyard or summer cottage, then timber as a construction material will be the best solution for a number of reasons, which we will discuss below. But in order for the work to be done efficiently and quickly, it is very important to correctly calculate the timber for the bath, it is this part of the process that our review will be devoted to, in which we will analyze all the important nuances using a specific example.

In the photo: on the network you can find a wide variety of plans for baths made of timber, you just need to choose the one that suits the layout and is quite simple to implement

Why the bar

Consider the main advantages of this material and its advantages over other options:

Important! Among other things, it should be noted that the buildings made of timber weigh less than any other option, while their heat retention indicators meet the highest standards.

Profiled timber is good because the elements fit together as tightly as possible.

Settlement process

In order to understand as much as possible in detail, we will divide all activities into two stages and consider each of them separately.

Training

The calculation of a beam for a bath from a beam begins with the following steps:

• First of all, you need to decide on the dimensions of the future building, they can be different, from the most compact options to solutions with an attic floor and a terrace. It all depends on your personal preferences and the availability of free space on the site. Remember that there are standards for the location of the bath, regulating the distance to the fence, well, bathroom and neighboring buildings, all these data can be clarified with specialists;

One of the options for the correct location of the building on the site

• Then it is necessary to select a project, which will become the main reference point in all further work. Based on the project, a drawing of a bath from a bar is made, which is approved by the relevant authorities, only after that work can begin. Most often, the implementation of this stage is entrusted to special design organizations, you submit a sketch you found or made on your own, and they draw it up in accordance with the standards;

We will analyze the process using this example - it is very simple and very popular among developers

• Next, the size of the beam for the bath is determined, meaning such an indicator as the cross section of the elements. We strongly recommend not to use elements with a width of less than 150 mm, even this option freezes through at -29 degrees, and thinner bars will keep heat very poorly at all. If you want the building to be able to maintain a comfortable temperature without extra costs in winter, then it is best to use a material sized 200x200 or 150x200.

The thickness of the timber for the bath must be at least 150 mm

Now let's figure out how a bath from a bar is calculated, if you have a project on hand, then the process will not be difficult. Of course, you can also use a calculator for calculating a beam for a bath, you can find it on the net without problems, but if the structure is simple, then you can do it yourself in a matter of minutes.

The work is carried out in the following sequence:

Some manufacturers of raw materials on their websites have a calculator for calculating a bath from a bar for the convenience of customers

• We will consider the project shown in the previous chapter, in which the size of the building is 3x4 meters, there is one external partition, the length of which is also 3 meters. Since even the internal partitions in the bath are recommended to be made of the same thickness as the external ones, we will calculate the total length of the walls: 3 + 4 + 3 + 4 + 3 \u003d 17 linear meters. Also immediately note to yourself that you have two walls of 4 meters and three walls of 3 meters, this will be needed a little later;
• Next, you need to calculate the number of timber, for this you need the height of the structure, in our case it is 2.55 meters, and the height of the timber itself, let's say you have chosen a good option 150x200, that is, the log house will consist of 15 rows;
• Above, we determined that we have 3 three-meter and 2 four-meter walls, by simple calculations we get the result of 45 wooden bars three meters long and 30 bars four meters long;
• Since materials are sold in cubic meters, we will translate our pieces into the desired units of measurement. One linear meter has a volume of 0.03 cubic meters, that is, a three-meter element is 0.09 m 3, and a four-meter element is 0.12 m 3;
• The calculation is simple - 0.09x45 \u003d 4.05 cubic meters of timber 3 meters long and 0.12x30 \u003d 3.6 cubic meters of elements 4 meters long, you have the exact length result in your hands, so you will get exactly what you need, and in during the work, the amount of waste will be minimal.

Important! If you purchase a ready-made kit, then you don’t have to count anything, since you will be supplied with everything required for the work, this option is also attractive, although it is associated with additional financial costs.

In the end, approximately the following result will be obtained - a small functional building that keeps heat well even in the coldest period of the year

We hope that our simple instructions helped you understand the features of the process, especially since there is nothing complicated in this, and you can make accurate calculations even without an engineering education. You can check the result using the bath beam calculator, if everything is correct, then the numbers will be the same.

Having decided to get a bath, the owners of suburban real estate often make their choice in favor of building from a bar. After all, it has the same advantages as a log cabin. But, at the same time, the process of its construction is simpler and takes less time.

Let's talk about the assembly of this design in more detail.

Required volume of material

Among the first problems, the question arises of how much timber is needed for a bath. To answer it, you need to take into account the design and architectural features of the future building. This includes the number of rooms and partitions between them, the height of the walls, the presence of a second or third floor.

Therefore, the exact figure can be given only after analyzing the design of the structure. Speaking of average values, we note that for the construction of a one-story bath measuring 6 * 4 meters, approximately 17 cubic meters of beams will be required.

When calculating a bath from a bar, you need to take into account the dimensions of the blanks that you plan to use in the construction process. The length of the elements is standard - it is 6 meters. But the cross section can be different. It can be from 100 * 100 to 200 * 200 millimeters.

First, we calculate the amount of material needed for one row of bars, otherwise called a crown. The resulting number is multiplied by the number of rows, determined by dividing the height of the walls by the height of one blank.

As a result, we get the volume measured in cubic meters. If you need to calculate the beam for a bath in pieces, then you can convert this number into the number of units. To do this, use the table below.

Total expenses

When planning future construction, the owner first of all wants to know how much money he will have to spend to implement his plan. Using averaged values, we will try to roughly calculate how much we are talking about in the case of a 3 * 6 meter bath.

To answer the question of how much a bath from a bar costs, you should take into account the cost of the following structural elements:

• strip foundation - to create a base for a log house, 3 * 6 m in size, you need to spend at least 10 thousand rubles. And this is if you do all the work yourself. Hiring workers will raise the price of the foundation to at least 25,000 rubles;
• log cabin - to create it, you first need to purchase material. To the question of how much a beam for a bath costs, we will answer that for a construction, 3 * 6 m in size, it will cost you about 50,000 rubles;
• roofing - will cost 10,000-15,000 rubles. This is the price of the materials needed to create an uninsulated gable roof covered with metal tiles;
• communications - their cost will cost about 30,000 rubles. But, as in the previous case, this is only the cost of acquiring the necessary products.

Let's sum up our calculations on how much it costs to assemble a bath from a bar. Its estimated cost will be 100,000 - 120,000 rubles. This is the minimum amount determined taking into account the fact that you will carry out most of the necessary work yourself.

It is preferable to use glued beams.

Thanks to them, you can save on the subsequent decoration of the walls of the bath.

If you have enough money, you can order the creation of this building in a construction company. Such ready-made baths from a bar cost an average of 250,000 rubles. How much will an ordinary one-story steam room, built according to a standard project, cost you.

Ready built turnkey

Choice of timber

Inexpensive log baths require high-quality material for their construction. Therefore, you need to know how to choose the right one.

1. there should be no cracks on the bars - this applies not only to large, but also to small cracks. Even the smallest of them will inevitably expand during the shrinkage of the building. Moisture will get into them, resulting in rotting of the material;
2. the presence of blue spots is also unacceptable - they are a sign that decay processes are actively progressing in the wood. Do not try to reduce the cost of a bath from a bar by using low-quality raw materials. Such savings will lead to a significant reduction in the life of the entire building;

There shouldn't be spots like this.

1. if there are wormholes or traces of bark beetle activity on the surface, then it is also better to refuse to use such material.

When buying a bar, pay attention to its geometric shapes.

They must be even.

Elements that have distortions will cause a lot of trouble when laying them.

This will lead to unnecessary waste of time and effort.

Log house assembly

Consider the most important aspect of creating a log bath - this is the procedure for creating a log house. Instructions for its construction begin with the creation of the first rows.

Laying the first crowns

For the first row, choose the thickest bars. After all, it is they who will have to bear the brunt of the rest of the structural elements. Therefore, it is worth taking blanks with a section of 200 * 200 mm as them. All other elements will have a size of 150 * 150 mm.

First, along the entire perimeter of the foundation, at a distance of 25 cm from each other, wooden slats are placed, treated with an antiseptic for a bath. Their thickness should not exceed 15 mm. These elements are needed in order to protect the lower crowns of the log house from decay. The remaining gaps then need to be filled with insulation or mounting foam.

After that, we make the first crown with our own hands, connecting the workpieces to each other using the “half-tree” method. You can use other connection options instead.

Ways of connecting blanks

The construction of the main part of the log house

The general procedure for building a log house looks like this:

1. crowns are laid and aligned relative to each other;
2. holes are made in them for driving dowels;
3. fastening pins are hammered into the prepared recesses.

In this case, it must be taken into account that the diameter of the hole must match the size of the dowel. They should be drilled at a distance of 1 - 1.5 meters from each other. The recess itself should pass through one beam and end in the middle of the underlying element.

Similarly, you need to lay all the rows with your own hands, with the exception of the top two. They do not need to be fixed, because then they will still have to be removed to install the ceiling.

Between the crowns it is necessary to lay a heater for the bath. It can be jute, tow or even moss. It is best to use the first option.

It is a roll material, which is very convenient to use. It is gradually unwound and attached to a tree with a construction stapler. There is no need to caulk the cracks afterwards.

In the photo - laying jute

If you use tow or moss, then the process of caulking cannot be avoided. It is made after shrinkage of the bath. Using a hammer and a wooden spatula, we hammer the insulation into the gaps between the blanks.

Before proceeding with the assembly of the bath, you need to calculate the amount of timber per bath. This will save you from a number of possible problems during construction. Then you need to purchase the required amount of material, choosing among it those blanks that do not have external defects.

If funds allow, then you can order the creation of a steam room in a construction company. Its specialists will calculate the amount of timber per bath and perform all the necessary work on its installation. All this will cost about 250 thousand rubles.

You can save a lot by doing all the assembly work yourself. In this case, you will pay only for building materials, which will amount to 100-120 thousand rubles.

Using timber as a building material for a house has a lot of positive aspects. This product is environmentally friendly, affordable and, accordingly, the most popular. Just keep in mind that the construction of a wooden house requires preliminary preparation and carefully calculated estimates. After all, a well-thought-out plan will allow you to distribute costs evenly and prevent unnecessary costs.

Peculiarities

When choosing a timber as a building material, you need to remember that it has several types, each of which has its own distinctive properties. The most acceptable is a tree 140x140 mm. And also the timber can be of natural moisture, profiled and glued. The first option is the most common, since its cost is much lower than the others. It is quite durable and has a beautiful appearance that does not require additional finishing work.

The profiled type of timber is more airtight. A house made of such material does not need additional insulation, since during installation it is fixed quite tightly. The shrinkage is approximately 5%. Its reduction can be achieved due to the horizontal internal cut of the timber. The final fastening of the bars to each other is provided by the “thorn-groove” rim connection system.

Many owners of wooden houses understand how important this parameter is. The amount of shrinkage depends on many indicators: the time of sawing the tree, climate, construction time and laying technology. For planed and facing logs, shrinkage is more than 10%. Therefore, the beam in this case has its positive aspects.

The glued look is quite expensive, due to the fact that there is practically no shrinkage. This advantage allows you to start the operation of the building immediately after the completion of construction work.

When a house is being built from a log house, you should let it stand for a while. Do not immediately cut openings for future windows and doors. It is necessary to wait for shrinkage. Only after the box has stood, it is possible to cut openings through the crown. For uniform shrinkage, the walls are assembled on wooden dowels, which do not allow horizontal twisting of the timber. And also "winter" wood is more suitable for building a house, as it is drier. Therefore, shrinkage is affected by the time factor when the tree was cut down.

As stated earlier, glued and dry planed timber does not need a "rest" after erection. The percentage of shrinkage for such types is either insignificant or completely absent. Only now the cost of such a bar exceeds by 20-60% of the profiled version. If, nevertheless, cracks appear in the walls between the joints, then these places need to be caulked, for example, with moss or jute felt.

Just don't worry. The appearance of cracks is a common and natural process that must be taken into account when building a house and choosing a certain type of timber for it.

Cubic capacity per 100 square meters or 120 square meters. m can be calculated independently, taking into account the recommendations of experts. It should be that there is a formula for calculating cubes, to know the weight of the material and how much timber it takes to build a house, for example, with a section of 200x200 mm.

Projects

Drawing up a project for the future home will allow you to know exactly what kind of house it will be, what material and where it will be used, and most importantly, how the cost estimate will be drawn up. Preliminary preparation will significantly save not only the budget, but also the time spent on construction. The project should take into account the size of the house, the number of rooms and their area, the number of floors, the presence of additional buildings adjacent to the main housing. You also need to specify the location of window and door openings.

To calculate the dimensions, remember that the length of the timber is 6 meters. If the wall of the house exceeds this number, then the beams will have to be joined.

All these difficulties can stop the entire construction process. So, If you are not sure that you can completely cope with all the work yourself, you should contact a specialist. In this case, although it will be necessary to overpay, the costs will be justified.

Before erecting the foundation, you need to dig a trench 70 cm deep, and the width will depend on the number of floors. Standard values ​​are 40-50 cm.

Next, you need to make a mixture of gravel and sand, which is laid in trenches. After completing all these points, a formwork of 1 meter is installed. Only then can concrete be poured, the proportions of the components of which will be determined by personal preference. A more liquid mass is only suitable if there are no gaps in the formwork.

The construction of the walls is the laying of beams in rows. The first strapping row must be carefully treated with an antiseptic.

All crowns are pulled together every 1.5 m with special nails measuring 6x200 mm, or they are also called dowels, to prevent horizontal twisting of the beams when the wood dries. Thus, wall shrinkage can be reduced. Arrange the dowels in a checkerboard pattern, and cut a vertical sample in the corners.

The roof usually consists of a supporting structure and a metal tile roof. For reinforcement, a crate is used. When building a roof, the first step is to tie the upper crown with a beam with a section of 5x15 cm. Then you can install rafter legs from boards 100x40 mm with a gap between them of about one meter. For the fronts, boards with a section of 25x150 mm are used, then the installation stage of the crate comes.

If the roof is made of soft material, then you need to cover it in two layers in order to better protect the house from moisture. If the project provides for an attic that will be used as a living space, then it will be necessary to purchase thermal insulation and install it before the final installation of the roof.

A house made of beams has its own distinctive features. This applies to the very type of tree, taking into account its size and characteristics. Therefore, it is necessary to approach the preparation and writing of the project, having familiarized yourself with all the nuances, so that there are no difficulties at the initial stages of construction. A frame, two-story house with an attic can be 8x8, 9x9, 9x7, 10x10, 6x9 or 9x10 m in size.

How to calculate?

Building a house is a rather complicated process, but it's worth it. After all, the result will be your own suburban housing, which can be located next to a forest or lake. This will allow at least a few times a year to live in the fresh air or even move to permanent residence. It actually sounds great to be inspired to build your own home. Only now, many make the same mistake when building housing, which can lead to freezing the entire process.

Wrong calculations are the main enemy in construction. Any extra figure in the project drawings or estimates can lead to serious consequences. Therefore, it is worth paying special attention to the correct calculation of all sizes and the required amount of building materials. All measurements generally depend on the following factors:

• type of timber used;
• the number of bars;
• the number of bars in 1 cubic meter;
• what house project is used.

To calculate the amount of timber in 1 cubic meter, the simplest calculation method is used. To do this, calculate the perimeter of the house, multiplied by the height. The result is then multiplied by the thickness of the material. The total represents the quantity to be purchased. Just keep in mind that cutting out door and window openings will significantly reduce the amount of timber. Therefore, you need to add 20% to the total. This allows you to get the final result. For internal walls, the calculation method will be similar.

The first crown is much thicker than the others. For him, the calculations are performed separately.

Having received data on the amount of timber required per 1 cubic meter, you can find out exactly how many pieces you need to buy. No need to calculate the volume of the product right in the store with a tape measure. The thickness and height of each beam may vary, so you should decide in advance what size you need. The thickness can vary within a given range, namely:

• 100x100 mm;
• 100x150 mm;
• 150x150 mm;
• 150x200 mm;
• 200x200 mm.

The height depends on the interventional seams. The fewer of them, the faster the construction work. As for the width, this indicator is more important. Especially when building a house for permanent residence, for which a beam with a thickness of 200 mm is suitable. Products of different thicknesses and widths differ from each other, and it is extremely thoughtless to acquire bars of unequal sizes. Learning all the nuances is extremely important. Thus, you can save money and not become a victim of a dishonest lumber seller.

All calculations must be made at the stage of project development. By studying the prepared drawings, it will be known how much and what material is needed. If you feel incompetence in this matter, then you should contact construction companies or read the information on specialized sites. On the Internet, you can also find ready-made projects with all sizes and the number of materials needed.

Everyone strives to do something with their own hands. This kind of work brings more pleasure. And building a house yourself is really a great achievement and the result of a huge amount of work done. Timber is a very good building material. It is healthy and absolutely safe. Wood, unlike other materials, does not contain harmful impurities and has a positive effect on human well-being. For example, it can maintain an optimal indicator of humidity in the room.

To make a beam, they take a whole tree and cut out rectangular beams.

Conifers are best suited as the strongest and most durable material. In addition, the resin very well prevents the product from rotting.

Yet even such a high-quality and natural material has its drawbacks. It requires constant impregnation that protects the tree from the process of decay. The next disadvantage is the high cost, especially for glued timber. If the material is not properly dried, then its quality will deteriorate significantly.

Building your own home involves solving many questions and problems. One of the key questions is how much will your future home cost? This cannot be calculated without an accurate analysis of the required material. It's one thing if you decide to order the construction of a turnkey house. The firm will take care of the billing. Another thing is if it is decided to build housing on its own. How to calculate the foundation? How much does it cost to build walls and roofs? How to provide a house with communications? Consider only one of the important components of the upcoming expenses - the calculation of the timber for the house. There are many calculators on the Internet for online calculations of the amount of timber. But since we decided to build a house with our own hands, we need to understand this important issue.

Before proceeding with the calculation of the timber for the house, you need to make several important decisions:

• determine the purpose of the future home,
• choose the material from which the house will be made,
• select a material supplier.

Let's deal with each of the points. We did not mention the size of the house and its number of storeys. To calculate materials, you must have a project with the exact dimensions of your object. You can make preliminary calculations so as not to make a mistake in choosing the size of the building that you can afford.

Why is it important to know the purpose of your future home? The thickness of the walls that you will lay will depend on this. For a spring-summer stay in a country house, a wall with a thickness of 90-100 mm is suitable, but for permanent residence, a wall thickness of at least 150 mm is required. The choice in favor of a thinner wall will result in the cost of insulation or heating the house. Of course, you should also not forget about the dimensions of the building, the choice of the beam section will also depend on this.

With the choice of material, everything is simple. The calculation of walls from edged, profiled or glued beams has a number of features. The edged beam has a height and width that will actually be used for the wall. The profiled beam has a general size (it is for these sizes that you will have to pay the cubic mass to the supplier) and a working size (which is actually used to build the wall). The working size differs from the general size of the spike, which can be from 5 to 20 mm. It would seem a little, but in terms of the whole house, a significant amount comes out.

The choice of a supplier before calculations is due to the fact that there is no strict standard for the production of profiled or glued beams. The overall dimensions of the material, the size of the spike may differ. Probably, everyone is also concerned not only with the calculation of the volume of timber per house, but also with the calculation of the total cost of the material. Do not rush into choosing the cheapest option. Low price is usually the result of low quality. But even a high price is not a guarantee of quality. It is better to choose a supplier with a long history of production and recommendations from buyers or developers in your area.

If you do not take into account the dimensions of the house, then you need to start the calculation with the choice of the dimensions of the beam, which can affect the project as a whole: a thin beam will not allow you to build complex projects, and a more massive one will require recalculation of the weight of the building and its load on the foundation. It may be necessary to recalculate the number of screw piles or the depth of the tape.

Calculation for a house from edged timber

Houses made from ordinary sawn timber are distinguished by simple projects, and calculating the amount of timber for such a house is a simple task.

First of all, it is necessary to calculate the number of rows of timber required to achieve the design height of the walls. To do this, we use the formula:

Number of rows = height of walls / height of 1 beam

The use of interventional seals will lead to a slight excess of the design height of the log house, but shrinkage will bring everything to the designated parameters.

Next, the total perimeter of the walls and partitions is calculated, which will also be made of timber. Often, a bar for partitions is used with a smaller thickness. For example, for walls, a material with a section of 150x150 mm is used, and for partitions - 100x150 mm. The height of the beam is always the same, so the number of rows for load-bearing walls and partitions will be the same. In this case, we consider the total length of the bearing walls and separately calculate the length of the partitions. Now it remains to calculate the volume of the beam:

Ask an expert

Timber volume = number of rows * wall length * (timber height * timber width)

Separately, we calculate the volume for partitions and for walls. Now it remains to summarize these volumes and multiply the result by the cost of one cubic meter. Now we know the cost and volume of a timber wall kit for our house.

Calculation of a house from glued or profiled timber

Almost every manufacturer will offer you a free calculation of the volume of timber for your home. But what if you decide to compare two manufacturers who produce material of different sizes, then it is better to do the calculation yourself, since the calculation of the volume performed by the manufacturer may be subject to bargaining. In the case of self-calculation, you will already be able to operate with the final numbers. Of course, they will be approximate, without deducting window and door openings. And in the case of buying a profiled beam with moldings (without bowls and a project), which is the cheapest material, you can’t do without calculating the volume.

As in the case of edged timber, we calculate the number of rows for a given wall height:

Building a wooden house requires careful preliminary calculation and drawing up the most detailed estimate. Any large construction project is associated with significant costs, and it is important to initially correctly assess the financial possibilities and present all future costs.

An important expense item is the foundation, but the “box” itself will become the most expensive part, so you need to perform a preliminary calculation of the material for a house from a bar. In this case, it is advisable to consult with a professional architect and builders who know the real prices on the material market.

Which timber to choose for construction

First you need to choose the material for the house from the timber. It differs both in characteristics and in cost:

• The cheapest option is the usual bar of natural moisture. It is the most common, but the least reliable. During the drying process, it can significantly deform, which leads to the formation of cracks and crevices in the walls.
• Dried timber - wood material that has undergone preliminary chamber drying. Most of the natural moisture is removed from it, so it will be more reliable, but the cost will also increase significantly.
• Profiled timber is an even more expensive type of material that will allow you to build completely smooth walls without gaps between the crowns. A special system of spikes and grooves on the top and bottom sides will allow you to build a building with the most durable walls.
• Glued laminated timber - the leader in cost. This is not exactly a bar, since it is not made from solid wood, but from several layers of wood glued together. Such material requires long processing, and it will be very expensive.

Thus, the calculation of material for building a house from a bar begins with an analysis of the construction market and the choice of a suitable material. When this issue is resolved, you can proceed directly to the calculations.

How much material is required to build a log house

The calculation of the material for building a house from a bar can be carried out using a special calculator program that is posted on construction sites. This will speed up the calculation, but the result will still only be an approximation. You can also calculate the material manually using the following parameters:

1. Bar section. It depends on the required thermal conductivity: for a house without additional insulation, a beam with a section of 200x200 mm is required: it is quite expensive, so future owners often prefer to purchase thinner and cheaper material, and then insulate the building with inexpensive materials. It is permissible to build a building for permanent residence from a bar with a thickness of 150x150 mm or 150x100 mm.
2. House dimensions. The standard project is a building made of timber 6x6 meters in size, as it will allow you not to connect the timber to each other.
3. The height of each floor. The minimum height from floor to ceiling is 2.5 m, often it is made higher so that later you do not limit yourself in the choice of furniture and finishes.
4. Area of ​​window and door openings. It is clear that the larger the window area, the less material is required. When developing a building project, the dimensions of the openings are indicated in the drawings, these values ​​\u200b\u200bare used for calculations.

An example of calculating materials for a standard house

It will be of great help in calculating the required amount of timber for building a house. But let's try to perform simple calculations on a simple example.

The calculation of materials for a house from a bar requires making fairly simple calculations that make you remember school geometry lessons.

Preliminary calculation of the material for a log house:

It is required to build a small house with linear dimensions of 6x6x2.5 meters. For construction, you need to purchase an ordinary bar with a section of 200x200 mm. It is planned to make a door with an opening size of 800x2000 mm in the building, in addition, it will have two windows measuring 600x800 mm.

Let's move on to the calculations:

• The perimeter of the house: 6 * 4 = 24 meters. We multiply this value by the height: 24 * 2.5 \u003d 60 square meters. meters - the total area of ​​\u200b\u200bthe walls.
• We calculate the area of ​​windows. We multiply 0.8 * 2 \u003d 1.6 square meters. m. - door area, 0.6 * 0.8 * 2 \u003d 0.96 m. - area of ​​\u200b\u200btwo windows. These values ​​​​must be subtracted from the total area of ​​\u200b\u200bthe walls: 60 - 1.6 - 0.96 - 57.44 square meters. m. - this is the area of ​​\u200b\u200bthe house.
• Since the thickness of the timber is 0.2 meters, the volume of the walls is calculated as follows: 57.44 * 0.2 = 11.488 cubic meters of timber will be required for construction.

Important points when calculating the material

If you need to build a house from a bar, the calculation of materials will always be approximate. It is imperative to add at least 15% to the obtained value, which will be required for trimming, damage, arranging corners, etc.

The timber is required not only for the construction of the box, but also for the installation of rafters, floor logs, ceilings, etc. As a result, in the final calculations, the amount of timber increases by about a fifth.

The exception is the construction of a house from a finished house kit. In this case, together with the architect, the exact amount of materials that will be required for construction is calculated, and all parts are pre-treated in the factory.

A ready-made set of numbered parts arrives at the construction site, from which the building is being erected, like a large constructor. All the details are exactly adjacent to each other, nothing needs to be adjusted and modified. You will have to buy only fasteners and insulation, and the work can be completed faster.

The calculation of lumber should take into account not only the purchase of the timber itself. You will need an inch board for the construction of a rough and fifty for a finished floor of a given area, material for the construction of a roofing pie and other expenses.

Each wooden element used in construction must be treated with antiseptics and fire retardants, the finished house needs to be painted or otherwise finished. The walls can be sheathed with drywall and additionally insulated.
