Bar 100x150 6 meters how much in a cube. Basic and additional calculations of wooden beams during construction

In preparation for the construction of a frame house, the construction of a roof and the assembly of log crowns, the developer has to deal with the purchase of timber.
This material is used for the manufacture of various wooden structures, so its assortment includes dozens of items. To eliminate errors, you need to determine as accurately as possible how much timber is in a cubic meter.

The "mathematical model" of this operation is simple. To calculate the volume of any rectangular object, its length is multiplied by its width and height. However, in practice, when buying a large number of timber of different lengths and sections, you can get confused and overpay a considerable amount.

In this article, we will talk about the important nuances of calculating the volume of sawlogs and give easy-to-use cheat sheets for converting linear meters of timber into cubes.

Be careful at the timber warehouse!

Given the high cost of edged timber, its purchase must be treated responsibly. Sellers, as a rule, use the price per 1 m3. When calculating the roof truss system, wall frame, floor beams and floor, customers receive running meters. Additional confusion is introduced by production length standards, which range from 3 to 6 meters (0.5 meter increments).

It is not difficult to put everything “on the shelves” in this matter. Let's say that for construction you need a bar with a section of 100x50 mm, and its total length is 100 running meters (p / m). To calculate the volume of edged wood, you need to convert the cross-sectional area from millimeters to square meters and then multiply them by the length: 0.1x0.05x100 \u003d 0.50 m3. We get the price of a given amount of timber by multiplying its volume by the cost of one cubic meter.

And here is another equally important question: how to control the amount of sawlogs that the seller releases to you? Here it is necessary to take into account not only the cross section, but also the length of the material.

Let's say that we need a beam 4 meters long (total length 100 p / m). In this case, the volume of one piece will be equal to: 0.1x0.05x4 = 0.02 m3. Dividing the purchased amount of material (0.5 m3) by the volume of one bar (0.02 m3) we get exactly 25 pieces.

In practice, round numbers are rare, so the required amount of timber most often turns out to be fractional. We will not give the seller that part of the lumber that remains after the decimal point. Better pay him up to a whole number of bars.

Consider an example. 63 linear meters of timber are purchased (section 100x180 mm, length 6 meters). We consider the purchase volume: 63x0.1x0.18 = 1.134 m3. We divide it by the volume of one bar (0.1x0.18x6 m / n \u003d 0.108 m3). We get 1.134 / 0.108 = 10.5 pieces. The seller will not cut half the timber for us. Therefore, when calculating, you need to pay him up to a whole amount and pick up 11 bars.

With a profiled beam, the cross section of which has a complex shape, they proceed in the same way as with a regular one. To determine the cross-sectional area of ​​a given material, its total height (the distance from the bottom edge with the groove to the top mark of the spike) is multiplied by the width.

Considering the amount of timber in 1m3 in the warehouse, take a tape measure and measure the actual cross section of the purchased material. It may turn out that instead of the 100x200 or 150x150 mm promised by the seller, he was delivered thinner material. Even 1 centimeter reduction in the transverse dimension of the sawlog results in significant losses for the buyer.

Another important nuance is the technological deviation of the length of the timber. It can reach 5-7 centimeters, since the ends of the logs are not cut off during processing. Remember that the seller does not have the right to add these extra centimeters to the total length.

Tables for quick calculation of the volume of timber

It is not always convenient to count on a calculator how many pieces of timber in a cube, especially when buying a large batch. The seller's data can be easily controlled using ready-made tables. Here, for standard sizes of sawlogs, information is given on the volume of 1 beam and the number of pieces in 1m3.

Table for counting edged timber 6 meters long

Dimensions (mm) Volume of 1 piece (m3) Pieces per 1 m3
100x100x6000 0,06 16
100x150x6000 0,09 11
100x180x6000 0,108 9
100x200x6000 0,12 8
150x150x6000 0,135 7
150x180x6000 0,162 6
150x200x6000 0,18 5,5
180x180x6000 0,1944 5
180x200x6000 0,216 4,5
200x200x6000 0,24 4
250x200x6000 0,3 3

This table can also be used when buying a 3-meter beam. To do this, the volume of 1 piece must be halved, and the amount of material in one cube multiplied by 2.

Recall that, by definition, lumber is considered to be lumber with a thickness and width of 100 mm or more. Therefore, we deliberately did not include the dimensions of wooden blanks of a smaller section in the table in order to maintain formal accuracy.

Let's look at the data on the volume and number of boards of running sizes in a separate table:

Dimensions (mm) Volume of 1 piece (m3) Pieces per 1 m3
25x100x6000 0,015 66,6
25x150x6000 0,0225 44,4
25x200x6000 0,03 33,3
40x100x6000 0,024 41,6
40x150x6000 0,036 27,7
40x200x6000 0,048 20,8
50x50x6000 0,015 66,6
50x100x6000 0,03 33,3
50x150x6000 0,045 22,2
50x200x6000 0,06 16,6
50x250x6000 0,075 13,3

To calculate the volume and quantity of a 4-meter beam, you can use the following cheat sheet:

Dimensions (mm) Volume of 1 piece (m3) Pieces per 1 m3
100x100x4000 0,04 25
100x150x4000 0,06 16,66
100x180x4000 0,072 13,88
100x200x4000 0,08 12,5
150x150x4000 0,09 11,11
150x180x4000 0,108 9,26
150x200x4000 0,12 8,33
180x180x4000 0,13 7,69
180x200x4000 0,144 6,94
200x200x4000 0,16 6,25
250x200x4000 0,2 5

As can be seen from the table, almost the entire range of bars here turns out to be fractional. Therefore, for an economical purchase, you should use our advice on paying the seller up to the whole amount of timber.

How to do it practically? Let's take an example. Let's say that we bought one cubic meter of a 4-meter beam with a section of 100x180 mm (according to the table, 13.88 pieces are obtained). The price of 1m3 is 6500 rubles. Up to 14 pieces of bars, we need to pay extra 14-13.88 = 0.12. The volume of this "piece" is (0.12 x 4 meters = 0.48 m) x 0.1 x 0.18 m = 0.00864 m3. We multiply it by the price of 1 m3 and get 0.00864 m3 x 6500 rubles. = 56.15 rubles.

Remember that the purchased volume of bars must include a margin (loss during cutting during operation). Therefore, the result obtained in the process of theoretical calculation of the roof truss system or other wooden structure must be multiplied by a factor of 1.3. After this adjustment, you can start settlements with the seller.

In addition to determining the volume and price of the purchased material, you need to know the weight of 1m3 of timber in order to order transport of the appropriate carrying capacity.

The weight of a cubic meter of timber depends on the type of wood and its moisture content. The approximate weight of 1 m3 of dry pine is 510 kg (raw - 890 kg).

The average weight of one cube of dry spruce bars is 450 kg (raw - 790 kg).

The weight of dried oak wood is in the range from 700 to 800 kg/m3, and wet (freshly cut) - from 980 to 1030 kg/m3.

Dry larch timber weighs 650 kg/m3. Freshly sawn material of this type of wood weighs 840 kg/m3.

Wood is a very comfortable and popular building material, thanks to which a person can build his own home. During the construction of a wooden house, it is possible to live in an environmentally friendly environment and not worry about your health. Even scientists advise everyone to build their house from natural materials. In order to understand how much timber is contained in one cube, you can use both the previously compiled tables and special formulas.

meter per cube ratio

To determine the task, it is important to make the following calculation:

  1. For example, let's take the most common length size - 6 m. Put the material into the furnace so that the cross section forms a square meter.
  2. As a result of the fact that the dimensions of the presented product are 100x100 mm, you get a stack of 10 by 10 products. After multiplying these numbers, we get the value 100.
  3. The length is 6 m, and we are considering m3, then you need to take 1/6 of the total amount of building material. Thus, 100 should be divided by 6 to get an approximate number of 16.6667.
  4. In this case, it is not necessary to round up to an integer value, because in this case there will be nothing to add the shortage. Therefore, if the question is this way: how many beams are 100x100 in a cube, then the answer will be: 16.6.

The video tells how much 100x100 timber is in a cube:

Quantity 150x150x6000

It's not that hard to do the calculation. To calculate the pieces of timber, you need to divide 1 m3 by the volume of one product. In turn, the volume will be made up of the multiplication of length, width and height. So, to determine the amount of bursa in one m3, it is first necessary to determine the volume of a single lumber. The procedure is as follows:


Since the most common length size is 6 and 4 m, we will consider the calculation of the cubic capacity for the most popular dimensions.

Table of various sizes in one cube

Table 1 - The number of different sizes of one cube

Length 4 meters
100x100 0,04 25

150x200 0,18 5,56
200x200 0,24 4,17

If you have the presented tables at hand, then there is no need to constantly do calculations. These tables contain cubed quantities for common lengths such as 4.5, 6, and 7 m. They contain rounded to hundredths of the required data. However, for a length of 4 m, you can leave such a table yourself, because the developed formulas come to the rescue.

Quantity of timber 150x150 in 1 m3

If you are going to use 150x150 m burs for building your house, then you can calculate their number in 1 m3, adhering to the following plan:


Comparison of timber 100x100 and 150x150

If you need to determine how much volume the selected natural material occupies, you need to multiply the volume of one product by their total number.

Consider a 100x100 material. Its volume will be 0.06 m3. Now you need to multiply the resulting value by the amount of lumber. As a result, you will get a number that will indicate the number of cubes. Similar arithmetic operations must be performed for a beam measuring 150x150 mm.

But, when calculating the presented material, it is necessary to take into account the following recommendations:

As you have already understood, it is very simple to make the presented calculations, and you can do it yourself, without involving specialists. If you know how many timbers you need to build your house, wholesale prices, then you will be able to make the process of purchasing building material accurately. After all, the construction process should take place with the calculation of the number of units of lumber for one or another wall, floor or stairs.

Wood is a very popular building material, which today is produced in various variations. But it is necessary to start the construction of the structure only after all the calculations have been completed. Only in this way, you will be able to carry out the correct purchase of material and not spend extra money and save on construction. You might be wondering about the pros and cons of kiln dried profiled lumber. Listed at the link.

Comfortable housing should be warm in the cold season and cool in the sweltering heat. Therefore, many choose wooden houses. The heat-insulating and noise-reducing properties of wood are closely combined with high reliability and durability of the entire structure.

The material for the walls of a wooden house is logs (previously peeled of bark, sawn to one size) or timber. Particularly fast are the works on the construction of walls from planed, profiled timber. A kind of profiled material is a product with a glued structure. The manufacturing process of such a bar consists in the fact that individual well-finished boards are lubricated with glue, compressed together under great pressure. This material is highly durable. He has absolutely no shrinkage.

Advantages and disadvantages of timber 150x150x6000

The market offers lumber, both with a flat surface and with a semicircular front part. In this case, the walls will resemble the shape of a log house.

The main advantages of using timber are:

  • ease of transportation and storage (smooth geometric dimensions allow you to compactly place the material, increasing the volume of transportation);
  • resistant to cracks, deformations;
  • ease of installation, no special equipment is required;
  • reduction of construction time;
  • a tight fit of the timber to each other allows to reduce the heat output through the walls and thereby reduce the cost of heating the room;
  • aesthetics (walls look even, neat and attractive).

The disadvantages are:

  • high price and deviation from the format of environmentally friendly material due to the use of various impregnations that prevent the process of decay (refers to a beam with a glued structure);
  • fire hazard. The requirements for the laying of power supply systems are increasing.

The advantage of a house made of timber is its weight. It is much lighter than those made of concrete and brick. Therefore, the load applied to the foundation will be much less. The weight applied to the base of the building is the primary characteristic in the design of the foundation of any structure. How important this is, we will determine with a simple example, by calculating the mass of load-bearing structures (only walls) of a certain object.

Mathematical calculations

For ease of calculation, consider a square house with a side of 6m (this is the standard length of the most popular timber, the size of which is 150 * 150 mm) and a height of 3m.

How many cubes in 1 bar

Initially, for the calculation, using a conventional calculator, we determine the area of ​​\u200b\u200bthe front side of the beam (it will be needed when calculating the amount of material for building walls) and how many cubes in one beam are 150x150x6000.

S b \u003d a * l, m 2, where:

  • S b - area, m 2;
  • a - height, m;
  • l - length, m.

Substituting the initial data, we get:

S b \u003d 0.15 * 6 \u003d 0.9 m 2.

V b \u003d S b * d, m 3, where:

  • V b - volume, cbm
  • d is the width of the material.

V b \u003d 0. 9 * 0.15 \u003d 0.135 cbm.

Quantity and weight determination

Knowing the volume of one beam, using the reference information on the moisture content of wood, we determine how many pieces are in one cube of a beam 150x150x6000 and its weight.

N - the number of pieces in one cubic meter of timber, determined by the formula:

  • N k \u003d 1 / V b \u003d 1 / 0.135 \u003d 7.4 pieces, we round the centimeters to an integer and get 8 pieces.

The weight of one cube, taking into account the density of wood, will be M k \u003d 1m 3 * ρ, kg, where:

  • ρ - wood density, kg / m 3 ( according to the tabular data of reference books it is equal to 520 kg/m3).
  • M k \u003d 1 * 520 \u003d 520 kg.

Calculation of footage

It should be noted that on the first row of the wall laid on the foundation, it is advisable to use a forest that is more moisture resistant in its characteristics - from larch. Knowing the size of the house (the perimeter of the structure taken as the basis for the calculation is 24 meters), we calculate how many meters are in one cube of this beam, and also whether it is enough to install the basement row - the crown.

Previously, the calculation showed how much timber is contained in one cube (N) - 7.4 pieces. With a length of one unit of material (l) - 6m, the total length of the beam will be:

  • L \u003d l * N to, m.

L= 7.4 *6 =44.4m , which fully meets the required demand.

Calculation of the total weight of the forest for the house

Now, to determine the total amount of wood required for installation, we find the area of ​​​​four, identical sides of the walls of the box of the house (we take for calculation the width and length of 6m, and the height of 3m).

S k \u003d 4 * a * h, m 2, where:

  • a is the width of the side, m;
  • h – side height, m

S to \u003d 4 * 6 * 3 \u003d 72m 2.

How much material is needed for the house

The amount of material needed in pieces is calculated by the formula by dividing the total area of ​​​​the walls of our building by the front area of ​​\u200b\u200bone beam, calculated at the very beginning of our task:

  • N \u003d S c / S b \u003d 72 / 0.9 \u003d 80 pieces, which is in cubic meters of wood:

V \u003d N / N k \u003d 80 / 7.4 \u003d 10.81 m 3.

Calculation of the total load

And finally, we approach the final calculation, knowing the mass of one cube, we determine the total load of the constructed walls in this example, on the foundation of the house:

  • MS \u003d M k * N \u003d 520 * 10.81 \u003d 5621 kg (5.621 tons)

Calculation results

The calculation showed that the walls made of pine timber bear a relatively small load on the base of the house. During the construction of walls made of brick and concrete, along with an increase in the labor intensity of the work, the total mass of the building would increase several times.

An unequivocal conclusion cannot be drawn. And a brick dwelling has a lot of advantages. You need to make a thoughtful and balanced decision. A durable and strong structure is the advantage of a brick. And if the goal is to install a house in a short time with an investment of a minimum amount of money, then a wooden house made of timber would be a good option.

Mathematical formulas and construction. What common? Much if you decide to build a house, controlling the process or on your own. By applying the desired formula, you can calculate, for example, timber 150 150 how many pieces in a cube? Or find out the features of the foundation by calculating the load of the structure. Many questions arise before the start of construction. We will answer some in our article.

Don't know what makes up the cost of a house? Can't decide what kind of foundation you need for a house made of timber? Let us explain using the example of calculations for a material with a section of 150x150, which is popular in the construction of residential buildings, baths or garden houses. What is easier than coming to the seller, talking about your project and buying what they advise. But not everywhere the goods correspond to the voiced information. If you know the exact amount of material in one cube, take a tape measure with you, you won’t spend extra money, you won’t sell air.

Any lumber, including profiled or glued, is sold at a price per cubic meter or running meter. You can calculate the cost of one piece, knowing the exact size and volume of the material. Similar values ​​\u200b\u200bcan be found in lumber parameter tables or calculated independently. Let's give an example: It is necessary to find out how many pieces with a section of 150x150 in one cube. The length of the element can be different, but 6 meter logs are more popular. We translate the values ​​into meters to make an accurate calculation: The volume of one piece \u003d width * depth / height * length of the wood. V= 0.15*0.15*6 V= 0.135 m3 One element has a volume of 0.135 m3. Let's calculate how many such logs 150x150 in 1m3? A \u003d 1 / V, where A is the amount of material in pieces, V is the volume of one piece. A \u003d 1 / 0.135 \u003d 7.4 pcs.

We get that in one cubic meter there should be at least 7.4 pieces of timber 150x150x6000. But there are dishonest manufacturers trying to make more money from one cube. They simply reduce the cross section, passing it off as 150x150. You can meet the size: 140x140; 135x135. Using the calculations presented above, you can easily calculate how much you will be deceived. We recommend that you always take a tape measure and measure each log in order to buy exactly a section of 150, not 140. Usually the price of a material that does not comply with GOST is lower, but as a result, the material may not be enough in volume. Additional searches for lumber, shipping will require more savings. We suggest that you familiarize yourself with the numbers of the main types of section: Table of volume, piece quantity of timber with different sections

  • W - width, mm;
  • H - height, mm;

The table will help you navigate the volume of one piece of material of any section, the number of pieces of each size in a cube of lumber. Thus, knowing the above values, you can calculate how much timber is required for the construction of an individual house, bath.

Let's calculate how much timber is needed for a wooden house

If the parameters of the future construction are known, for example, you need a 6 × 6 house from a 150 × 150 timber, you can calculate how much material is needed in piece quantity, volume. The sequence of calculations for a 6 × 6 house without additional internal partitions made of the same material: The house has two floors, the ceilings are 2.5 meters high. We find out the total volume

material, adding the length of the log house along the perimeter, multiply by the height of two floors. P \u003d 6 + 6 + 6 + 6 \u003d 24 m. - the perimeter of the house; S \u003d 24 * 2 * 2.5 \u003d 120 m2 - the area of ​​​​the house. A beam with a section of 150x150 and a length of 6 meters was chosen as a building material. To find out the number of cubes for a house from a 6 × 6 timber, we multiply the resulting area by the thickness of the material: V material for the walls of the house \u003d 120 * 0.15 \u003d 18 cubes - net size. It is necessary to take into account marriage, docking and other nuances that require taking lumber with a margin of 10-15%.

We get 20 cubes of timber 150x150 for a log house 6x6. We did not take into account the openings of windows, doors, gables. They compensate each other for material costs. Let's translate the resulting volume of lumber into a piece quantity of timber 150. Knowing the volume of one board, we divide the total volume by the volume of one piece: 20 / 0.135 \u003d 148.14 pieces of timber 150 by 150 for the walls of a 6x6 house.

What kind of foundation is needed for a house made of timber with a section of 150x150?

Thinking about the amount of wood, volume, it would not be superfluous to know the weight of the lumber to calculate the foundation. Under the house from a bar, you can pour a different foundation. Depends on the soil, the load of the house during operation. It is easier to calculate the weight that will put pressure on the base, pour the desired foundation. Perhaps it will be a pile structure. Let's calculate how much the same 6x6 pine house weighs. Any wood has a weight (density), depending on:

  • places where wood grows;
  • type of wood;
  • storage and processing conditions.

It is either dry or wet. There is an average specific gravity calculated for each type of wood. Pine has a density of 530 kg/m3. Multiply the indicator by the total cubic capacity, find out how much the log house weighs. The weight of a house with a roof, ceilings, furniture, partitions, residents will be twice as much as a log house made of profiled or glued material weighs. Let's calculate: 20 * 530 \u003d 10600 kg - the weight of a wooden frame. 10600 * 2 \u003d 21200 kg - the approximate weight of the entire structure that puts pressure on the foundation. Having calculated how much the house weighs, you decide which foundation to choose for future construction. All calculations are conditional, have average values, because different lumber exerts different pressure.

Profiled can be of natural moisture or dry, which differs in the shrinkage of the house and its weight. For glued beams, their indicators. Therefore, we took average figures for calculation. Using our formulas, calculate how much your structure will weigh. If the same material with a section of 150 by 150 is taken as the basis. Some builders are wondering how much a cube of timber 150 * 150 weighs. Its weight depends on the type of wood, type of material. Table: How much does a cube of timber 150 * 150 weigh

*The table contains average values. They change from:

  • storage conditions,
  • wood drying quality,
  • environmental influences.

Having considered the important points in calculating the cubic capacity of the necessary material for building a house from a bar, it remains to find out how much it costs?

How much does a 150x150 beam cost in different regions?

The cost of lumber depends on many factors. Today, a beam with a section of 150 by 150 is in sight. This size is in demand because it meets the requirements of customers in the speed of erection of the structure, low thermal conductivity, and constant availability from customers. The cost depends on:

  • type of timber - profiled or glued;
  • from humidity - natural or dry;
  • wood harvesting sites;
  • remoteness from the construction site (cargo transportation services);
  • fame, reliability of the manufacturer;
  • direct sale or through intermediaries.

Here is a table of prices for pine timber:

LocalityThe cost of one cube of timber 150x150x4000/150x150x6000, rubles
profiledglued
natural humiditydry
Moscowfrom 10 000from 12 000from 22 000
St. Petersburgfrom 10 100from 12 200from 22 300
Novosibirskfrom 10 200from 12 500from 22 700
Krasnoyarskfrom 10 000from 12 300from 22 500
Tyumenfrom 9800from 12 200from 22 500
Ufafrom 9 800from 12 300from 22 500
Permianfrom 9 500from 12 000from 22 000

The cost of profiled timber per cube does not depend on the length of the material. If you buy wood 150x150x4000 and 150x150x6000 by the piece, the price will be different. For example, in Novosibirsk, one piece of profiled timber 150x150x4000 of natural humidity costs from 920 rubles, and the same timber 6000 m long costs from 1380 rubles. It is more profitable to buy lumber from a large supplier in bulk. Then the price may be lower than indicated in the table. Knowing the intricacies of choosing and buying a bar, you can accurately answer the question of a bar 150 150 how many pieces are in a cube, what is its cost, how much is required for the construction of a low-rise structure. Make purchases correctly, benefit and enjoy.

Starting the construction of a house or other object, we first draw up an estimate of the necessary building materials. The correct calculation of the materials used in construction allows you to avoid a shortage or, more importantly, an overrun.

This rule is relevant for any construction and wooden houses are no exception.

Calculation of lumber for construction

Currently, most of the suppliers and distributors measure lumber in cubes (cubic meters). An experienced buyer will easily determine how much and what he needs, but a person who buys this product for the first time to build a house can face significant problems.

So, let's try to figure out how to determine the amount of material in a cube and protect ourselves from the dishonesty of a cunning seller.

Easy to count lumber

Many years of experience in buying boards for construction shows that the conversion of this raw material into cubes of pieces is not something particularly difficult. The only thing that is required is to calculate the volume of one beam or board, taking into account its width, thickness and length.

So, how many pieces of 100x150 timber are in a cube, or how many pieces of the most popular 50x150 board are included in a cube?

Let's start with the board. The most popular board today has a thickness of 5 cm and a width of 15 cm. At the same time, the standard length is 6 meters. How to get volume?

From the school mathematics course, we recall that for this it is enough to multiply all the above dimensions. As a result, we will get the volume of the board in cubic meters. In this case, the calculations will look like this: 6.0 x 0.15 x 0.05 = 0.045

What does the result mean? The result of the calculations means that the volume of the board is 0.045 cubic meters. Therefore, there are 22 boards in a cube.

But what about the beam

A wide range of applications for this type of profiled timber extends to:

  • erection of walls of houses, warm verandas, baths, arbors, buildings for household purposes;
  • production of blanks used as load-bearing elements;
  • use as a basis for arranging floor ceilings and interfloor ceilings;
  • strengthening door and window openings of buildings;
  • production of frameworks of interstorey transitions, flights of stairs and platforms.

The popularity and demand for this material is explained by:

  • ease of installation (up to do-it-yourself construction);
  • no need for adjusting operations (saving time);
  • simplicity and convenience of storage and transportation;
  • the possibility of erecting objects of various configurations with different standard sizes.

But let's get back to how many pieces are in a cube of timber 100 by 150. It is also easy to make such calculations.

The standard length of a profiled beam is 6 meters, while the thickness is 10 and the height is 15 cm. In the same way as in the example described above, we carry out the necessary calculations: 6 x 0.15 x 0.10 = 0.9.

Therefore, in one cube we get 11.1, that is, 11 bars.

It would seem that everything is really very simple. But due to such calculations, you can overpay when buying building materials.

What is the trick of calculations

Let's say you are interested in how to calculate a cube of timber 150x150. According to the above formula, we multiply the dimensions and get the volume of one bar 0.135 cubic meters.

How many bars are in a cube? It turns out seven bars, right? But the trick is that there is not an integer number of pieces in the cube. This is where unscrupulous traders can deceive us.

For example, you need a board cube - here are 22 pieces for you. Need a cube of timber - please - 7 bars. As a result, to build a small 6x6 house, you need 52 timber. By simple calculations (52/7 \u003d 7.43 cubes), it can be established that we will not be given 3 beams.

Learning to count correctly

Let's return to the already tested example of 52 beams with a cross section of 150x150 and a length of 6 meters. We calculate the volume: 52 x 6 x 0.15 x 0.15 \u003d 7.02 cubes. Actually, you have to pay for 7.02 cubic meters, and as a result you get 52 bars and no less.

What else to consider when counting lumber

What else do you need to pay attention to when counting how many 100x150 timbers are in a cube? In other words, are there other tricks?

It is important to consider that there are two main varieties of this product on the market: “calibrated” and “non-calibrated” bars. In addition to different costs, these products show a difference in tolerances from the specified dimensions. Thus, at the calculation stage, you need to decide which tolerances are important and which can be ignored.

For example, if the purchase of a 100x150 product is planned for the installation of SIP panels, then calibrated lumber is needed, which has the most accurate standard sizes and does not require additional fitting.

Another important point - the length of the product can exceed 6 meters. Due to technological features, the average size is not 6 meters, as the accompanying instructions show, but 6.05.

The reason for this phenomenon is that the manufacturer, in order to save time and reduce labor costs, does not process the ends, leaving this “honorable duty” to the buyers. So, rarely, but some especially cunning sellers try to take into account these surpluses, calculating cubic meters.

Now, have you calculated how many 150 by 200 timber are in a cube and purchased it in accordance with the features of future construction? At the same time, be prepared for the fact that you have to solve the problem of storing material.

Features of lumber storage

It is no secret that construction is carried out much faster than the construction of a brick or stone house. But, despite this, it is necessary to take care in advance of finding a place suitable for storing building materials.

High-quality timber, the price of which is justified, is delivered to the customer with a moisture content of 12%. This is the best indicator, thanks to which you can be sure that the construction will take place without long-term shrinkage. But the problem is that with improper storage, the moisture content of wood can change.

How to save timber without changing the initial moisture parameters?

First of all, you need to prepare a place for storage. This place will be a platform with a flat and dry surface. Pallets are laid across a flat area, on which it will be possible to put a beam.

Tip: if there are no pallets, you can use boards, sleepers or fragments of beams.
By laying lumber on an impromptu stand as in the photo, you prevent moisture from penetrating into the wood.

A number of experts are of the opinion that supports for the bars are not enough and the construction of additional frame structures may be required. That is, on occasion, the canopy will protect the stacks of lumber from the negative effects of precipitation.

How to lay the timber for storage?

So, pallets or other wooden structures are laid across the site. Now on top of these devices you need to lay the bars. Each beam is laid at a small distance from each other. The gap between the bars (at least 2 cm) must be maintained in order to ensure the flow of air for ventilation

Additional protections

It is highly likely that the lumber you purchased, despite proper storage, will acquire additional moisture. The fact is that sometimes it is not enough to close the products from above and below. To completely eliminate the possibility of wetting a stack of lumber from the sides and ends, you need to cover them with plastic wrap.

Important: it is unacceptable to completely wrap the timber with a film in order to avoid the greenhouse effect.

The question arises, does the timber need moisture protection only during storage or even when a house is built from it? Of course, the optimal humidity parameters will need to be maintained both before construction and after. You can’t wrap a naturally finished house with cellophane, and therefore protective paint and varnish coatings are used.

The market offers a wide range of varnishes for outdoor work. High-quality varnish, subject to proper application, forms a thin but wear-resistant coating, which for several years will prevent moisture from penetrating into the pores of wood.
