How many tons in a cube of edged boards. How many square meters of a board are in a cube: dimensions of products, number of parts, calculation of volume and area. Calculation of the cubature of edged boards

Beam and board - one of the oldest building materials but it does not lose its relevance today. At the same time, the cost of these lumber makes buyers carefully approach the accuracy of calculating their required quantity.

Now you can find on the World Wide Web the necessary tables for calculating the required number of cubic meters of building materials, but a skilled owner should be able to calculate it on his own.

How many boards are in a cube 50 by 150 by 6000

As you probably already understood, the calculation of lumber is carried out in cubic meters. At the same time, the cube of the board and the beam can have different overall dimensions. Therefore, for an accurate purchase, you need to understand the size of this cube for a more accurate calculation. The most common lumber cube has dimensions of 50x150x6000 mm.

We calculate the required volume easily and simply

It is very easy to calculate cubic meters of a board or a bar. To do this, you need to have elementary knowledge of geometry, which we were told back in school. Thus, to determine the desired cubature, you must initially multiply the width (l), thickness (s) and length (b) indicators.

For example: s boards × l boards x b boards = 50 mm × 150 mm x 6000 mm = 45000 cm/cube.

We remember that a cubic meter is equal to 1,000,000 cubic meters, that is, 100 cm x 100 cm x 100 cm.

1000000 cc/cm: 45000 cc/cm = 22.22 pieces boards in one cube.

How to calculate how much timber in 1 cube?

We offer a simple calculation so that you do not get lost with the question of how to find out how much timber is in a cube. These calculation options are suitable if you know the dimensions of the timber. For example, let's take a bar 260 x 260 x 6,000 mm (6 meters). The same can be done for a beam measuring 3 meters, 4 meters, 5 meters.

The formula for calculating the volume of a beam:
100mm 100mm 6000mm = 0.1m 0.1m 6m = 0.06m3

The formula for calculating the beam in pieces:
Bar length - 6 meters
1m 3 / 0.06m 3 \u003d 16 pcs / m 3

Complicated? It seems to be no! But if the calculation causes you difficulties, just use our table. The table contains a calculation for all known sizes of timber, which are given in GOST 8486-86.

The page contains answers to simple questions people have:

  • How much timber
  • How many cubes of timber
  • Cube of timber how many pieces
  • How much timber do you need
  • How many in one cube
  • How many pieces in a cube
  • How many bars are in a cube
  • How to calculate how much timber in 1 cube

Why do you need to know how much timber is in 1 cube?

There are two reasons for this:

  1. You can immediately calculate the total price of the volume of timber you need. To do this, you need to know the volume of 1 piece of timber, the price for 1 cube and how many pieces will be needed to implement your plans.
  2. You can calculate the total number of timber units needed to complete the project. And you can do this by knowing how many cubes are required for work, and by calculating the number of pieces of timber in 1 cube.

Construction works require the solution of many different issues, among which the most important task is the selection and purchase of lumber. It is not difficult to calculate how many linear meters of boards and timber will be needed during the construction process. That's just the price of commercial wood is indicated for 1 cubic meter, and this often causes difficulties for novice home craftsmen. The ability to correctly select and calculate the amount of edged or unedged lumber in a cube will save money and avoid a situation where, after completion construction works on the site there is a pile of unused boards.

Classification and characteristics of lumber

The very name "lumber" suggests that this type of construction raw material is obtained by longitudinal sawing of tree trunks into circular or band saws. For the production of boards and timber, several sawing methods are used:

  • tangential (in a circle),
  • radial.

Tangential sawing involves the movement of the saw tangentially to the annual rings of the tree, which reduces the amount of waste, and hence the cost of building materials. The boards obtained in this way have a beautiful, pronounced pattern, therefore they are often used for finishing purposes. Disadvantages of circular sawing include the wood's tendency to shrink and swell, and a significant difference in texture as the cutting tool approaches the center of the log.

In the sawmill industry, several methods of sawing the trunk are used.

With radial sawing, the cutting line passes through the core of the tree, so the output of boards will be less and their price will be higher. However, if necessary, get wood High Quality use exactly this method. This is due to the fact that, compared with the tangential method, radial sawing boards have halved swelling and shrinkage rates. In addition to the sawing methods discussed above, a mixed method is also used, which combines the advantages of the first two.

The concept of lumber actually includes not only the traditional molding, which is most often seen in the construction markets. A complete list of products that are obtained when sawing logs includes:

  • board;
  • beam;
  • bar;
  • lagging;
  • croaker.

The last two types of lumber are waste, which absolutely does not prevent them from being used for certain types of construction work, as well as for finishing purposes.

Boards

Boards include rectangular lumber with a thickness of not more than 100 mm and a width to thickness ratio of at least 2:1. Depending on the degree of processing, the board can be edged and unedged. The first is a finished product without bark and with evenly sawn edges, while the second is a "semi-finished product" taken directly from the saw frame.

The edged board has even edges and a constant width along the entire length of the lumber

Most often in construction boards of such standard sizes are used:

  • thickness - 25 mm, 40 mm, 50 mm, 60 mm;
  • width - from 75 to 275 mm with gradation through 25 mm;
  • length - from 1 m to 6.5 mm in 250 mm increments.

Boards of other sizes can be obtained by cutting or planing standard lumber, as well as by making an individual order for sawing round timber.

Unedged board has a lower cost, but without finishing, its scope is limited

The parameters of lumber used in construction are standardized and determined according to the current GOST 8486–86 for softwood and GOST 2695–83 for hardwood.

bar

Timber is called lumber, the cross section of which is a square with sides of at least 100 mm. The size of the beam in the diameter is unified and can vary from 100 to 250 mm in increments of 25 mm. The standard defines the length of products of this type from 2 to 9 m, but most often square-section lumber with a length of no more than 6 m is used. to sleepers.

The beam is an ideal material for the construction of frames and other wooden structures.

The bar differs from the bar considered above only in that its cross section does not exceed 100x100 mm. The typical length of the bar is also 6 m, and the size in diameter ranges from 40 mm to 90 mm in 10 mm increments. To simplify the classification, bars are often referred to as a rail, in which the cross section has a rectangular shape, and the ratio of thickness to width is at least 1:2. The standard range of edges of softwood slats looks like this: 16, 19, 22, 25, 32, 40, 44, 50, 60, 75 mm. For hardwood lumber, products of increased width are additionally provided, and the product line itself looks like this: 19, 22, 25, 32, 40, 45, 50, 60, 70, 80, 90, 100 mm.

A variety of bars and slats allow you to strengthen and make any wooden structure as stable as possible

Obapol and croaker

Obapol represents the very first cut of round timber, in which the outer surface remains untreated. Unlike obapol, the croaker can have a cut on half of the second side or an alternation of processed and unprocessed sections from the side of the bark. The value of obapol and slab in construction is secondary, since it is unaesthetic appearance and reduced performance characteristics allow the use of lumber of this type only for auxiliary purposes. Most often, slab and obapol are used as a fastening material, as well as for the manufacture of formwork, crates or flooring for scaffolding. This material is also interesting as decorative material for decoration of walls, fences and other vertical structures.

Despite external unsightliness, slab and obapol are widely used for secondary construction tasks.

Technology for calculating the number of boards in a cube

On the wood market, both edged lumber and unedged boards are presented, along the edges of which there is a wane. Depending on the type of wood products, several methods are used to determine the cubic capacity.

How to find out the number of edged lumber in a cube

The algorithm for determining the cubature of lumber is based on the formula known to every student for finding the volume of a rectangular parallelepiped. In order to find out the cubature of one board (V) in a cube. m, it is necessary to find the product of its length (a) by the width (b) and thickness (h) in meters V=a×b×h.

The desired figure will make it easy to calculate how many boards of this type will fit in one cubic meter of lumber. For this, 1 cu. m of lumber is divided by the volume of one product. For example, if you need to find out the cubic capacity of one board with parameters 6000x200x25 mm, then by substituting these numbers into the formula, we get V = 6x0.2x0.025 = 0.03 cubic meters. m. Therefore, in one cubic meter there will be 1 / 0.03 = 33.3 of such products.

The grooved board has a groove on one side and a ridge on the other. Since both of these elements are approximately equal to each other, their parameters can be neglected. That is why the size of tongue-and-groove lumber in diameter is measured without taking into account the locking part.

In the case of boards that have the same dimensions, the calculation can be simplified by substituting the dimensions of the lumber stack into the formula. Of course, at the same time, its laying should be as dense as possible, otherwise the gaps between the individual elements will affect the accuracy of the calculations. Given that the cost of individual types of wood reaches tens of thousands of rubles, such an error can result in a pretty penny.

To simplify the calculations, you can use special tables that allow you to quickly determine the cubic capacity or the amount of wood in 1 cubic meter. m lumber.

Table: the number of edged boards in 1 cu. m lumber standard length

Board size, mmThe number of boards 6 m long in 1 cu. mThe volume of one board, cube. m

50x15022,2 0.045
50x20016,6 0.06
50x25013,3 0.075

The cubature of timber of standard sizes can also be determined using the table below.

Table: the amount of timber in 1 cu. m lumber

Beam size, mmThe number of products with a length of 6 m in 1 cu. mVolume of 1 bar, cu. m
100x10016.6 0.06
100x15011.1 0.09
100x2008.3 0.12

150x2005.5 0.18
150x3003.7 0.27
200x2004.1 0.24

Very often it is required to determine the surface area (floor or wall) that can be covered with a board of one thickness or another with a volume of 1 cubic meter. m. To do this, you can use the formula S \u003d 1 / h, where h is the thickness of the lumber. So, one cubic meter of a 40 mm board will be enough to equip S = 1 / 0.04 = 25 square meters. m floor. To facilitate the process of calculating the area allows a table called a cubature. It contains data on the cross-section of boards, their number in 1 cu. m and the desired area that they can cover.

Method for calculating the cubature of an unedged board

Unedged lumber is not trimmed at the edges, so not only the size in the diameter of individual products varies, but also the width different parts one board. In this regard, it is possible to calculate the volume of a stack of raw lumber only approximately. The same applies to the calculation of the cubic capacity of a separate unedged lumber, although the error in this case will be much smaller.

So, to calculate the cubature of an unedged board, there are two constants - thickness and length, and one variable - width. To avoid complex calculations using differential algebra methods, the last parameter is simply averaged. To do this, the board is measured in several places and the arithmetic mean is found. For example, for a board with a diameter at the base of 400 mm, a width of 350 mm in the middle and 280 in the top, the calculated value will be (430 + 340 + 260) / 3 = 343 mm. Further calculations are carried out in exactly the same way as for edged lumber.

Most often, the width of an unedged board is determined only on the basis of measurements along the edges of the lumber. It should be noted that the accuracy of calculations directly depends on the number of measurements, therefore, in critical cases, their number is increased.

If it is required to find out the cubic capacity of a package of unedged wood, then the products are stacked on top of each other in such a way that the following conditions are met:

  • stacks must be aligned along the front end;
  • boards in a stack should not overlap;
  • it is not allowed to change the width of the package along the entire length of the lumber;
  • the protrusion of the outermost products beyond the stack should not exceed 100 mm.

By measuring the height, length and width of a package of unedged wood with a tape measure, the approximate cubic capacity is determined using the formula V=a×b×h. To find out a more accurate value, the result is multiplied by the stacking factor, which can be found in special tables.

Getting ready for construction frame house, the construction of the roof and the assembly of the crowns of the log house, 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 positions. 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 timber of different lengths and sections 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. Customers in the calculation truss system roofs, wall frames, floor beams and floors 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- technological deviation of the length of the beam. 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 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 1 m3 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.

On this page you can calculate the number of boards in one cubic meter. Also shown is a table of standard sections of lumber and a table of the number of boards (beams) in 1 cube for a length of 6 meters.
