Calculation of the construction of a house from a bar. Calculator for calculating the materials of a log house with siding, a slab prefabricated-monolithic foundation, a wooden beam ceiling, a corrugated roof

The beam is cut by specialists immediately under finished project structures where all the bars are fitted one to the other. The calculator for building a house from a bar allows you to accurately calculate,. The construction itself takes from several days to a couple of weeks, depending on the complexity of the project.

Material Advantages

The beam is made from solid wood, which guarantees the structure high environmental friendliness and a minimum percentage of internal cracks. The shrinkage of a house made of timber is much less than that of other materials, for example, rounded logs.

Glued laminated timber - the material is very durable, this is his undeniable advantage, since the house will not require any repair work or additional investment.

Choose timber from large manufacturers, factories are very responsible for the production and storage of material. Strict control of wood moisture, the accuracy of mating knots - this is what guarantees major producer and something that will significantly speed up and facilitate the construction of a house.

Shipment of material takes place in special transport packages, this protects the wood from impact. environment, humidity, precipitation and slight mechanical damage.

Well, practically the main argument when choosing is the final cost of the finished structure. Here the timber also wins, in comparison with others, it is available for almost any consumer who plans to build a house for a long time from high-quality material.

The cost of the beam itself may turn out to be higher than planned, but here it is worth calculating the entire project: due to the excellent thermal insulation of the beam itself, you can treat it more economically.

Timber structures are quite light, which, in turn, allows you to work with a less expensive foundation. Taken together, these facts indicate that the market price for timber may seem a little high, but, in the end, the whole project is cheaper.

From the additional costs, when using a bar, it will also be possible to exclude the costs of caulking: a profiled bar does not need this, and it will not be necessary to apply an antiseptic coating separately, the manufacturers will take care of this.

House design and construction calculations

Before you buy timber, make sure that you have a finished house project on hand. It is not necessary to order an expensive project for a new house, each construction organization will be able to offer you a choice of ready-made projects that this organization has implemented in the past.

This will effective solution, since the builders will already have experience working on such a project, they will be able to implement it in short time and without force majeure. Also, in each such project there is already a calculator showing the required cubic capacity.

If you yourself created the project, or there is not complete, but partial construction - an extension or a terrace, then you can calculate the costs immediately in the construction organization.

When planning to build on your own, you can use the resource called - a calculator for building a house from a bar. By specifying the footage, the program will helpfully calculate for you required flow material.

Be sure to remember that a house is not only a bar, it is also a foundation, interior decoration, tools for assembling a structure. Boards for partitions, rafters, scaffolding. There are enough nuances in building a house, which is why it is better to entrust the work to professionals.

They are more likely to save your money than spend too much. The percentage of marriage among professionals will be many times less, expendable materials are also used wisely: nevertheless, experience allows you to act more productively and faster than when building a house on your own. In addition, the construction organization is fully responsible for all stages of construction: from the study of the soil for the foundation to the coating roofing material and interior decoration.

Quality determines value

Summarizing all that has been said, it is worth noting a few of the most important points. The cost of the house will be calculated based on total costs for production.

Consider when choosing not only the cost of one building or finishing material, timber, for example, but also what kind of foundation this material requires, what kind of interior decoration, what the roof will be made of.

Only after that can we talk about the final cost of the structure and the benefits of a particular material. Be guided, first of all, by quality criteria.

Calculation of the roof in a house from a bar

Types of materials for wooden buildings

Before making a calculation of a wooden building, it is necessary to decide what material to choose for it. Currently, developers are offered the following lumber for this:

1. ordinary (sawn) and profiled timber from solid wood;
2. ordinary and profiled laminated timber;
3. calibrated (rounded) log.

These are the main lumber used in the construction of wooden buildings, but profiled laminated timber is considered the best among them. Its advantages are:

1. minimum residual moisture in the range of 10–18%, practically excluding shrinkage and deformation of wood;
2. perfect shape and precise linear dimensions material, which extremely simplifies and facilitates the assembly of the building;
3. increased strength in comparison with a similar bar made of solid wood;
4. no need for additional sealing of the seams between the bars.

These characteristics do not greatly affect the total amount of material for the construction of the building - except that the timber consumption will be slightly lower due to the reduction of waste losses.

Anyway preliminary calculation of a house from a bar at the design stage of the building will allow you to optimize the cost of future construction in terms of quantity and cost of material. In order to correctly calculate the consumption of timber, logs at the first stage, it is necessary to carefully prepare the project of the building and complete its detailing, taking into account the layout, dimensions, places for window and door openings.

General principles for calculating lumber for wooden houses

To calculate the total amount of lumber for a wooden building, you need to divide this procedure into three stages - according to the number of main structural parts of any building. Calculation of a house from a bar made with the following elements in mind:

1. walls and partitions;
2. floors;
3. roof frame.

For each of the named parts of the building, calculations are made, taking into account the purpose of each element. For example, outwardly similar wall and internal partition assembled from timber different section, therefore, the amount of material for structures of the same size can differ by more than twice.

Calculation of materials for walls and partitions

Walls and partitions made of timber or logs form a log house. These are the main load-bearing structures of the building, and the walls, in addition, are responsible for its thermal insulation. You can calculate the amount of lumber for walls and partitions using the following algorithm:

1.​ Walls are measured along the outer perimeter and height of the building. Minimum size section of timber for the house permanent residence is at least 150x150 mm. In this case, the width of the timber for the first (lower) crown should be greater than for subsequent rows.

2. The volume of material in cubic meters is converted into pieces, based on overall size timber. The resulting amount is rounded up to the nearest whole number.

3. The volume occupied by window and door openings is subtracted from the total amount of material.

4. For piers (partitions) and houses of seasonal residence, a bar with a section of 100x100 mm is quite enough.

Fulfilling preliminary calculation of a house from a bar, start with optimum thickness walls are 200–250 mm. This value guarantees proper thermal insulation, and the walls will not need additional insulation.

If you choose a calibrated log for a log house, then its diameter must be at least 220–260 mm. When calculating a wooden bath, the thickness of the walls from a beam in the range of 125–150 mm or from a log with a diameter of 200–240 mm is considered normal.

Developers who do not have enough experience may need help to draw up a building project, calculate the amount of materials. The easiest way to find it is on the Internet. Here you can buy a finished project, get help in the form of advice on the forums from people who have already put up a log house with their own hands. However, the scope of work on building a wooden house is not limited to the construction of walls.

Calculation of materials for floors

Ceiling and basement ceilings form the volume of rooms (rooms). Their basis is wooden beams, which are based on the foundation and bearing walls. To calculate the required amount of material for floors, the following requirements should be followed:

1. the step width between adjacent beams should not exceed one meter;
2. the optimal cross-sectional size of the beams is 100x150 mm;
3. extreme beams should be adjacent to the walls along the entire length;
4. the number of beams, depending on the orientation of their laying, is determined as follows: the length or width of the building must be divided by the step value specified in the project and subtract one unit.

To do it right calculation of a house from a bar from the point of view of the strength of the floors, the operating load of the building should be known or predicted. So it will be possible not to lay down excessive strength characteristics of the beams, saving a decent amount on this.

Where calculations are required load-bearing structures It is best to take the help of professionals. This is indispensable in the implementation individual project. The cost of design services is not so significant as not to consider such an option for preparing the construction of your own housing.

Calculation of materials for the truss frame

Unlike walls and ceilings, the truss frame has a three-dimensional configuration. Therefore, it is much more difficult to calculate it. In addition, it consists of many parts different sizes, it uses other materials besides timber. The roof design should take into account the following factors:

1. operational and wind loads;
2. type and slope of the roof;
3. type of roofing material and so on.

Fulfilling preliminary calculation of a house from a bar at the design stage of the roof, we must not forget that when building a roof, a bar of different sections is necessarily used. The step width between the rafters should not exceed 70 cm. The ridge beam and Mauerlats have the largest section. The truss frame must ensure the presence of roof overhangs, etc.

In this case, you will need the help of specialists more than ever. For example, you can buy a ready-made house plan from timber or logs to customize it to suit your needs. The main advantage of such a solution is to eliminate the risk of errors, which can be much more expensive than the payment for the received service.

In the calculation of the roof, it is also necessary to include the crate of the truss frame. It can be solid and lattice, depending on the chosen roofing material. Because window and door blocks most often they buy ready-made, on this preliminary calculation of a house from a bar can be considered complete. You just have to put the draft notes in order to proceed to the purchase of the necessary materials.

In order for your project to take on the proper form, you must complete calculation of a house from a bar finalization of its results. In the language of professionals, this is called the preparation of a material specification. This document allows you to control the amount of lumber in the range and the total cost of their purchase. The specification is made in the following order:

1. the volume of materials in cubic meters is summarized according to the main parameters, such as the cross-section and types of timber, width, thickness and length of the boards;
2. lumber is converted into pieces, which greatly simplifies the procurement process and makes it easy to control their quantity and assortment.

We want to note that the typical dimensions of timber, logs, boards have multiple values. You must take this circumstance into account when drafting a project. Otherwise, significant waste losses are inevitable. In other words, the dimensions of the log house should be measured in numbers of the same order as standard materials. All the information necessary for this can be found in GOST 8486-86, GOST 24454-80 and others. normative documents woodworking.

Final stage calculation of a house from a bar with the preparation of a material specification for the quantity and cost of lumber, it will provide you with indispensable assistance in assessing your own capabilities. At this stage, you can still make changes to the project: for example, reduce the cost of it or, conversely, use better and more expensive materials.

The main properties of wood: useful information

By implementing calculation of a house from a bar, the main characteristics of wood should be taken into account. This will provide rational choice materials and will allow you to perform a number of other important calculations (for example, when constructing the foundation of a house). Among the main properties and characteristics of lumber can be called:

1. residual moisture: it is not recommended to use wood with a moisture content of more than 23% in construction;
2. density - this parameter directly affects the strength of the material and the weight of the building;
3. resistance to moisture, rotting, insects - harms fir trees and other external factors.

In the aggregate of all the features, glued beams are best suited for walls. It has the lowest possible residual moisture, and, thanks to its multilayer structure, it surpasses analogues from solid wood of any species in strength. In addition, glued lumber is usually treated with antiseptics and flame retardants.

For walls and partitions, we recommend using profiled timber. It is significantly more expensive, but these costs will be fully compensated by reducing the time of work, the cost of finishing, insulation and other costs that are inevitable when using less quality materials. Now you can safely start building.

Timber houses are very popular and have a number of advantages over log houses. wooden houses. The geometrically correct shape of the beam (a rectangle or a square is obtained in the section) allows you to create more usable space, and it becomes much easier to calculate the amount of material needed to build a house. To do this, you need to know the length and height of all sides of the structure and multiply by the thickness of the beam.

Types of timber products

To date, on construction market you can meet a bar different section. So, they often buy lumber products with a section of 120x120, 150x100, 180x180, 200x150, 150x150, 100x100, 140x140 mm. All of them are purchased for certain structures. But the most popular is the section of the beam 150x150 mm, since it combines good value and excellent thermal insulation characteristics. Also, timber products with a section of 150x150 mm are simply laid, a pronounced number of seam caulked joints is obtained.

Plus, recently, prefabricated glued lumber material, that is, profiled, has been supplied to the market. When compared with typical lumber, it has increased strength properties, heat-saving characteristics due to tongue-and-groove joints, as well as lower shrinkage. Therefore, many experts recommend using it. There is only one drawback - the high cost of the material. The prefabricated glue beam has more than high cost, however, it is fully justified, since the service life exceeds the time of using conventional lumber.

Formula

Vbeam = wall height x wall length x beam thickness

By making calculations in this way, we get the required amount of material for building a house. Let's take a simple example. If you are going to build a house, the height of the walls of which will be 3 meters, and the length of the walls is 9 and 6 meters from a bar 150x150 mm, then you need to first calculate the perimeter. That is, we add up the length of all walls: 9 + 9 + 6 + 6 \u003d 36 linear meters. Next, multiply the resulting number by 3 meters and get 108 square meters. At the last stage, we multiply by the thickness of the beam, that is, by 0.15. As a result, it turns out 16.2 cubic meters. Thus, the question of how to calculate the amount of timber per house should no longer arise.

Calculation example

As you know, the sale of bars, boards on the market is carried out precisely in cubic meters. This is very often used by many sellers, who allow you to take the excess in your pocket, because buyers do not know how to calculate the cubic capacity of the timber. At the same time, it is not so difficult to find out the necessary cubic capacity. There is one easy method. So, if you purchase lumber of the same size, then you need to multiply the length of the beam by its cross-sectional area. Thus, you will find the amount in cubic meters in one unit of lumber. And then multiply this number by the number of units.

Let's give an example: if you bought 20 units of timber with a length of 6 meters and a section of 150 x 150 mm, then first we find the cross-sectional area of ​​\u200b\u200bthe lumber. To do this, we multiply 0.15 by 0.15 = 0.0225 m2. Then we multiply the resulting number by 6 (the length of the beam). As a result, it turns out 0.135 m3. Well, at the last stage, we multiply by the total amount, that is, by 20. The total cubic capacity of the acquired timber will be 2.7. That's enough simple method you can calculate the cubic capacity for any lumber. Applying this formula you will save a lot of money.

Due to its attractiveness, speed of construction, environmental friendliness, variety of colors and textures. Glued laminated timber in the modern construction market is considered one of the best building materials; in the manufacture of logs, they are sawn into lamellas of a certain width, which are glued together with extra strong glue alternately with longitudinal and cross section. The result is a particularly dense natural construction material. Before starting construction, prospective homeowners often consider how much glue-laminated timber is needed per house in order to make preliminary cost estimates and minimize waste. Before calculating, it is necessary to determine the dimensions of the future structure, draw up a floor plan. It should be borne in mind that the material will be needed not only for walls, but also for beams, gables, rafters, partitions and other wooden structures.

How to independently calculate the amount of lumber per house

When calculating, it is necessary to know the cross section and length of the bar that will be used in construction. The length of the bars is most often 6 meters, the thickness depends on the purpose of the planned building:

• 100x100 suitable for country houses, verandas, summer outbuildings, baths;
• 150x150 are used for residential buildings year-round living in the southern regions and the central strip, taking into account gas or wood heating;
• 200x200 is used in areas with a harsh climate and when electric heating in winter;
• 250x250 is used in the construction of massive cottages for laying out the first crown and during the installation of interfloor ceilings.

The simplest calculation required amount lumber is made by multiplying the perimeter of the room by the height of the walls and the thickness of the beams. But for a more accurate calculation during the construction of beams and interior partitions, you can use another method. To calculate, you will also need the height and length of the walls of the planned structure. As interior partitions gender and ceilings are made of lumber, it is easiest to calculate for each section on the plan separately and add up the result. To do this, you need to multiply the perimeter of the floor of each room by the height of the walls and the width of the timber. The result is a calculation of cubic meters per section. For accuracy, subtract the area of ​​​​the planned window and door openings, obtained by multiplying the length by the height. After calculating the volume in each section, you need to add up the results, and you get a complete calculation of the house from glued laminated timber.

If it is necessary to calculate the piece quantity of materials that will be spent on construction, the cubic capacity must be divided by the volume of one bar and the result obtained rounded up. To calculate the volume of one lumber, it is enough to multiply its width by the length and height. Having learned the amount of glued laminated timber required, you can calculate the cost of the house approximately. This should include the cost of loading and transporting building materials plus the error in the calculations.

How to calculate a house from glued laminated timber: an example

For residential buildings, the most optimal dimensions are 150x150. With such a thickness with a heater, good thermal insulation is created. If we take, for example, a house plan with a length of 7m, a width of 8m and a wall height of 3m, a bar width of 0.15m, then the calculation will be as follows:

(7 + 8) x2 = 30m - the perimeter of the house;
30x3 \u003d 90m2 - wall area;
90x0.15 \u003d 13.5m3 - the volume of bars for the construction of external walls.

For the accuracy of the calculation, you need to subtract the area of ​​​​all window openings and doors, which saves several percent of the total volume. To calculate how many materials will be needed piece by piece, you need to find out the volume of one bar: 0.15x0.15x6 \u003d 0.135m3. Now we divide the total volume by the volume of one bar 13.5 m3: 0.135 m3 = 100 bars with a section of 150 mm and a length of 6 meters, excluding openings.

An online lumber calculator for building a house and other structures will allow you to quickly calculate lumber, taking into account the size of the structure. In accordance with the result obtained, the calculation of dowels, heat-insulating tape and the total cost of the material will be carried out.
