How to calculate the cutting formula cube. How to calculate the cube of the unedged board. Planed Bar - What is his differences from the bar

When building work on the construction of a residential building, a specialist needs to perform a large number of various tasks, one of which are: drawing up and calculating the estimated value to the final decoration of the residential building. No compulsory, make the calculation of the required number of various building materials, which is quite difficult to do. Therefore, such knowledge - how many in Cuba boards is very important for a specialist who is engaged in the construction of a residential building and wishes to perform work as high quality and quickly in time.

CUSTOMER CLUB: Existing types of boards

To calculate how much the board pieces in Cuba, it will be necessary to know not only what exactly the board is the board, but it is worth understanding an important point that there are various types of boards and what is the opportunity to purchase in the modern market to fulfill various construction work. It should be noted that the cube of almost all materials, regardless of the variety of material, is calculated in the same way, that is, one defined method. Board varieties do not have the effect on the calculation of the cube of this building material.

Unfolded type of lumber are: timber, various edged boards, as well as unedged boards (are an exception when calculating the cube, because this process occurs a little differently). To the tipped species (which have special grooves, for the implementation of the joint) include: modern lining, block mobile, floor material, as well as imitation of a natural bar. When you choose to purchase a t-shut-off type of building material, then you will need to pay your attention that when calculating, only the working width of the board without spikes is used exclusively. If we talk about the block champion (imitation of the log), then when calculating the cubs take only the thickness in its highest point.

What quantity in 1 Cuba boards: execution of the calculation

Anyone, since his school times, it is clear how the cub is calculated. For this procedure, it is necessary to calculate the values, such as: length, width and height. A similar principle is used and for the calculation of the cube 1 of the board. It is recommended when performing such calculations, translate all existing values \u200b\u200bto meters. Cubature 1 boards, which has a section of 150x20 mm. and 6 m long, calculated as follows: 0.15 multiplies 0.02 and 6, so that the cubature of this boards will be 0.018 cubic meters.

Apply the volume formula V \u003d L * H * B (where L is the length, H is the height, B - width).

L \u003d 6.0; h \u003d 0.02; B \u003d 0.15.

Thus, V \u003d 6.0 * 0.02 * 0.15 \u003d 0.018 m 3.

To determine how many boards in one Cuba: 1 m 3 divide into the cube (volume of one board).

1 m 3 / V \u003d \u200b\u200bn pc.

1 m 3 / 0,018 m 3 \u003d 55.55 pcs.

Thus, the number of boards in one Cuba is 55.5 pieces.

Learn the cost of a specific type of board, when the values \u200b\u200bof its volume are known sufficiently easily: 0,018 is multiplied by the price of 1 cubic meter. When 1 cube of a certain type of board has a cost of 5,500 rubles, then the cost will be 99 rubles. At this point of calculation, there is some trick of sellers and managers in construction stores, because the material cubature is rounded to some entire values.

Such rounding is capable of bringing to this moment that the price of 1 boards (when 1 cube costs 5500) will be completely different values. In addition to all this, it should be noted that various boards for construction, which constitute a nominal length of 6 meters, is in fact the length is 6.1 - 6.2 m. It does not take into account when implementing this building material. This, applies to the acquisition of a significant number of boards. This is clearly clearly seen if the board is 150x20 mm for example. The number of boards in Cuba is 55.5 pcs. But, 55 pcs consider in Cuba, that when calculating the calculation will be a value of 0.99 cubic meter. In fact, this is the moment that overpayment for 1 cubic meter of this popular building material may be a value of 1% of the real price. For example, 5500 instead of 4995 rubles.

For the calculation of the cube for the unchanging board type, some other methods are used. When the conversation is about buying 1 boards, then the measurement of its thickness, and the total length is performed in a similar way, as well as when the edged building material is selected. In this case, the width for calculations is taken by averaged - between the great value and small.

For example, when the board width is 25 cm at the end, and on the other 20, then the average value will be approximately 22 centimeters. When, it is necessary to calculate the volume of a significant number of such boards for construction, then it will be necessary to decompose them so that the broader does not have differences from narrow, more than 10 cm. The main length of this material in the unfolded stack, indicatively the same should be the same. After that, with the use of a conventional roulette, an accurate measurement of the height of the entire existing stack of boards is performed, the width is measured (approximately on the middle). The result obtained is then needed to be multiplied by a special coefficient constituting a value from 0.07 to 0.09, in direct dependence on the existing air gap.

How many in 1 Cuba Boards: Special Tables

To calculate what exactly the number of boards of a certain width, length in 1 cubic meter, a variety of tables apply. The following shows several such specialized tables, where the cubature of the common and sought-after types of this material are indicated. Calculate the volume of various boards having different sizes, for example, material for the construction of the fence on its plot, it is possible on its own using the existing formula that is presented above.

Table of the amount of Unedged Board in 1 cubic meter

There are dozens of professions in the world related to the tree, and experts should be able to not only choose and handle the wood, but also to calculate everything. How to calculate the cube of the board, each specialist should know, because This pitch is basic before starting construction.

The main stage of the work

Calculate a little more complicated than the edged, due to the fact that it does not have 3 indicators, but 4. Often, the sellers are trying to provide their own cube, where incorrect data are specifically listed, so you always need to recalculate everything.

The volume of any lumber is considered according to the standard school formula - V \u003d ABC, where a is width, B - height, C - length. Thus, let the edged board have parameters 50x150x6000 mm, which are translated into meters, it turns out 0.05x0.15x6 \u003d 0.045 m³ everything is extremely simple and understandable.

But the unedged board is all a bit more complicated, because The width of the bottom and from above varies. With the help of a tape measure, the width of the boards from below and from above are made, after which the data is given to the average arithmetic. Thus, the volume formula will look like: V \u003d (A1 + A2) / 2BC, where A1 is the width of the lower edge, A2 is the width of the upper edge, B is height and C - length. In practice, let the upper edge (narrow) be 150 mm, and the lower 180 mm, height 50 and length 6000 mm, i.e. V \u003d (0.15 + 0.18) / 2x0.05x6 \u003d 0.0495 m³. It is these data will be used further for all computing.

This data can already be used to calculate the number of sawn timber per 1 m³. For this you need 1 / 0.0495 \u003d 20 pcs. All that remains after the comma, it is necessary to round up so that the whole number is. The volume of lumber each time is calculated individually so that the error can be avoided.

It is often revealed by an error when a wide side is taken as the basis, and the narrow is not taken into account, which gives a small visible error for the client (1-2 pieces with 1 m³), \u200b\u200bbut the seller wins substantial profits. If 1 board remains with 1 m³, then from each 19 m³ there remains another 1 m³, which brings super-profits. And taking into account the required volumes of material, even 1 house, these 5% pay off very seriously.

For example, a simple table will be given, where the widths of 150 and 180, and differs only length and height:

Summarizing

By themselves, the calculations are simple, because held according to the formulas studied at school. But during the process it is very important to approach the process with maximum scrupulousness to avoid errors.

Only the initial process may seem complex, but after 5-10 approaches everything will seem easier.

Before starting construction work, any owner of land real estate, which is supposed to build a residential building, wants to know how much material will be required. Financial costs will depend on the volume of building materials and their species, which some owners suffer a one-time is heavy, and they are forced to acquire various materials in stages. With low-rise house-building, the tree and products from it make up a considerable part. Therefore, it is desirable to know how much boards will be required and how much they will cost.

Thanks to the exact calculation of the number of boards, it is possible to save considerably and not to be deceived

Characteristics of wood materials

Currently, the building materials market offers various wood materials at a price in rubles per cubic meter. If an isopted how much boards are required to improve the floor, I would like to know their price. In addition, during construction requires various types of wooden products, characterized by form, sizes and price. Therefore, before studying the question of how much boards in Cuba, it is necessary to study the nomenclature of the proposed wooden products. The future homeowner, to build its future dwelling may require:

the profiled timing of a square or rectangular section, a smaller side of which exceeds 100.0 millimeters;
the bar size of which is:
x 16.0 ... 75.0 millimeters for dried products of coniferous breeds;
ü 19.0 ... 100.0 millimeters for hardwood wood.
edged, treated in three planes, a board, a thickness of more than 20.0 millimeters, the width of which fluctuates widely;
unedged board having two sculpting sides, the side edges of which are raw;
gorny, which is half-leaked from rounded lumber ;
terraced board http://www.ecowood.com.ua/catalog/terrasnaya-doska for flooring.

The greatest financial costs will be required to purchase the first three types of lumber, so the question of how much the issue in Cuba, Brous or boards is most relevant.

Accurate calculation of the number of sawn timber in one cubic meter (1 m³)

The task of determining how much in Cuba boards is at the level of arithmetic tasks solved in the first grade. The source data for calculation how many in Cuba timber, bar or boards are:

z - the number of boards (pieces);
h - the thickness of the board (the smaller section of the cross section of the bar) in meters;
b - Lumber Width (meters)
L - Length of a timber unit (meters).

Volume (V) of one product (boards, timber or bar) is determined by the ratio:

V \u003d h × b × l, cubic meters,

and the number of lumber units in a cubic meter will determine how:

Of course, this calculation is quite approximate - it does not take into account the gap between the individual products, the type of processing of the board (tipped, planed), the length of the length and other sufficiently specific trifles. According to the above formulas, it is impossible to calculate the amount of unedged board or hill. However, to determine what amount to take with me to the leaschend, and whether there is no one thousand rubles, the accuracy is enough. More accurate results can be obtained using a table method of calculation.

Table determination of the amount of sawn timber

To determine how many boards in 1 cube, the calculation table contains graphs and strings. The lines indicate the cross section of the sawn timber, and in the graphs (rows) there are calculated values \u200b\u200bof the volume of one board and the number of boards in one cubic meter. In principle, these values \u200b\u200bare calculated, but taking into account the correction coefficients. Consider the cutting (part) of the table how many boards in 1 cube. In this case, the conventions correspond to the formulas used in the above formulas.

If with the definition of weight and volume, for example, when buying liquids or bulk materials, no tasks appear, it is not all opposite with the timber. Here, the system of determining the volume of the need for this raw material causes a lot of questions, from the fact that no one wants to pay extra money.

Instruction

2. First, the measured batch of business cake should be sorted into 2 groups. One group make up the boards with a length of more than 2 m, other - less than 2 m. Laying in the stack is made with thick and thin ends alternately on various sides, while the surface of the hill remains at the bottom and above. The stack should be supercompact and tightly laid at right angles and have an identical height.

4. The volume of lumber from the wood of coniferous and hardwood is allowed to determine in two methods. The 1st method provides for the frozen of the entire bar or the board, and then the volume, later, the results are summed up.

6. Absolutely, it costs separately to dwell on the measurement of the Cubature of Round the woods . Here it is possible to measure all the logs and the width of the upper and lower ends. Special tables for which these calculations are made are referred to as the cubenesses that were discussed above.

7. Later, as the volume of the entire log is measured separately, addition is made, and the universal cube is obtained. At the current time, the corresponding computer program exists.

After all the ideas for the construction of the house are worked out and the final version of the construction of a rounded log is chosen, the question arises, how much such a house will cost you. To determine cost of building a cut from a rounded log , it is necessary to know how many log cubes in this sruba. In this article, we will try to explain in detail how to perform the calculation of the cubature for the construction of a rounded log.

Calculation of the cubature of the cylindered log

The easiest way to calculate is made by the formula - πr². H.

Π — 3,14

r² - Radius of the rounded log in the square

N -length of the rounded log

We substitute the data in the formula:

3,14 * (0.11 m) ² * 6m \u003d 0.228 m3

So, we got how many cubes in one rounded log with a diameter of 220mm. Next, it is necessary to calculate how the number of logs in your home and multiply the resulting quantity on the cube of one logs (0.228m3). Calculate the number of logs in the wall can simply, but initially it is necessary to determine for itself, what a height will be the floor.

Calculation of lumber cubic - it's not easy, but necessary

It is also necessary to add to the resulting height of 7% on shrink if the log of natural humidity.

For example, the height of the first floor is 2.9 meters. The height of one log 220 mm minus the lunar groove will be 190.5mm. Next, we divide the height of the floor 2.9m on the thickness of the log without a groove - 0.19m, translating all the numbers in the meters in advance.

2.9: 0.19 \u003d 15.26 pieces. We obtained the required number of logs with a diameter of 220mm in order to build a floor with a height of 2.9 meters. You must not forget and add 7% on shrinkage at home. Total will be 16 crowns. Now, in order to learn the full floor of the house 6x6, 16 of the crowns, it is necessary to perform the following calculation:

16 (crowns) * 4 (walls) * 0.228 (volume of one log) \u003d 14.6 m3 logs. Now to find out the cost of a pinned log on the entire log house, you must multiply the number of cubes obtained on the rack of the log per cube. The cost of one meter of cubic cylindered logs can be found here .

To make the calculation for other login diameters, we offer to your attention a number of pre-calculated tables, using which you will surely find answers to your questions.

Method of calculating the mass and volume of knurling residues

One of the tasks in the development of the project of the technological regulation of the process of circulation of construction waste and demolition is the calculation of the mass and volume of the carrying residues formed under the cutting of green plantings (tree demolition) in the construction zone or demolition.

The official method of calculating the mass and volume of carrying residues for these purposes in the Russian Federation is not. The source data for such calculations is information about the vigorous trees (breed, height and thickness at an altitude of 1.3 m) and shrubs (young) given in the list of project documentation for the construction site (demolition).

This article presents the method of calculating the mass and the volume of carrying residues developed in our company. As a basis for its development, a tabular data of public-union standards for taxation of forests approved by the Order of the USSR State Committee of February 28, 1989 No. 38 was used.

1) Table 17 data "The volumes of trunks (in the crust) in young people in height and diameter at an altitude of 1.3 m" - to determine the volume of the trunks of the young slop and shrubs.

Cubature for round logs

As a result of the processing of the given data to determine the average ratio between the diameter (d), the height (H) and volume (V) of one barrel, the calculated form coefficient (KP from Table 1) is determined, which with an accuracy of +/- 10% makes it possible to determine the volume of the barrel by Formula Vst \u003d Kn * H * Pd2 / 4.

2) Table 18 and 19 data "The volumes of trunks (in the cortex) of woody rocks in height and diameter at a height of 1.3 m with an average form coefficient" - to determine the volume of the stems of various trees. As a result of the processing of the given data to determine the average ratio between the diameter (D), a height (H) and volume (VT) of one barrel, calculated coefficients are defined for some of the tree species shown in the table, which with accuracy +/- 10% allows you to determine the volume of the barrel According to the formula Vst \u003d Kn * H * Pd2 / 4. The calculated form coefficients are shown in Table 1

3) Table data185 "Weight 1 cubic. M and volume of 1 tons of wood of different breeds "- To determine the mass of wood, the mass values \u200b\u200bof one cubic meter of the corresponding wood of wood were used from the Count" Freckled ", or from the" dry "graph - for dry.

4) Table 206 data "The volume of bark, boring, stumps and roots" to determine the volume of bruises and branches, as well as stumps and roots in percentage terms to the volume of trunks. For calculation, the average values \u200b\u200bare used from the interval tables. The volume of branches and branches - 7% of the volume of trunks, the volume of stumps and roots - 23% of the volume of the stems.

5) Table of Table 187 "Fracture and Hamz Full Drive Coefficients" - to determine the shareholder volume of the branches and the branches from the complete-dried volume using the translated coefficient of equal to 10.

FKKO 2014 contains codes of the following waste:

1 52 110 01 21 5 Waste of branches, branches, vertices from forestry

1 52 110 02 21 5 Pumping Pumping Waste

1 54 110 01 21 5 Low-value wood waste (brushwood, dealer, stem debris).

Consequently, the calculation of the mass and volume of carrying residues must be calculated by type of waste:

the trunks of the treasured according to the bandwidth of the trees, young rigs and shrubs can be attributed to low-value wood waste (brushwood, dealer, fragments of stems);
sucia and branches - to the waste of bits, branches, vertices from forestry;
stumps and roots - to the waste of panties.

For the technological regulation of the process of convening construction and demolition, it is necessary to calculate the mass of waste, but for temporary storage in the bunkers of the drives and their export from the construction site, it is necessary to estimate the volume of carrying residues, and in the shareholder.

The calculation is made using the Exel application. Example of the EXEL page table caps are shown in Table 2.

The calculation was made as follows:

1) filling the source data according to the list of vocabulary;

count 2 - the number of the string of the sidelia;

graph 3 - wood breed;

count 4 - the number of trees;

count 5 is the minimum diameter of the barrel from the interval specified in the list of the statement;

graph 6 is the only value of the diameter of the barrel indicated in the list of the statement;

count 7 - the maximum diameter of the barrel from the interval specified in the list of the statement;

graph 8 is the minimum height of the barrel from the interval specified in the list of the statement;

count 9 is the only value of the height of the trunk specified in the list of the statement;

graph 10 - the maximum height of the barrel from the interval specified in the list of the statement;

count 11 is an additional number of trunks - if in the column "characteristic of the state of green plantings" n stems for a single tree, then in column 11 indicates (<значение графы 11>\u003d (n-1) *<значение графы 4>.

2) Calculation of the average value of the diameter of the barrel in the presence of an interval:<среднее значение диаметра ствола (графа 6)> = (<значение минимального диаметра (графа 5)>+<максимальное значение диметра (графа 7)>)/2;

3) determining the volume of one barrel<объем ствола (графа 12)> It is performed according to Vst \u003d Kn * h * Pd2 / 4, wherein the corresponding form coefficient from table 1, D is the average diameter of the barrel, H is the average height of the trunk. Calculation of the volume of one barrel:<объем ствола в куб.м (графа 12)> \u003d Kn * π * (<диаметр ствола в см (графа 6>/100)* (<диаметр ствола в см (графа 6>/100)*< высота ствола в м (графа 9)>/ 4);

4) Calculation of a dense measure of the volume of trunks VLL \u003d VT * NST, where NT is the total number of stems:<плотная мера объема стволов (графа 13)> = <средний объем ствола в куб.м (графа 12)>*(<число деревьев или кустов (графа 4)>+<число дополнительных стволов (графы 11)>). For one bush, the number of additional trunks is taken equal to 5;

5) Calculation of the folding measures (when storing or transporting, it is necessary to take into account the average volume of space occupied by trees or bushes:<складочная мера объема стволов (графа 14)>= <плотная мера объема стволов (графа 13)>* 4 / p;

6) Calculation of the volume of branches and branches, depending on the volume of the barrel, is made according to paragraph d) of this article:<объем сучьев и ветвей в плотной мере (графа 16)> = <плотная мера объема стволов (графа 13)> *<переводной коэффициент (графа 15=0,007)>. In the Folding measure - according to paragraph D) of this article:<объем сучьев и ветвей в складочной мере (графа 18)> = <объем сучьев и ветвей в плотной мере (графа 16)>*<переводной коэффициент (графа 17=10)>;

7) Calculation of the volume of stumps and roots from the volume of the barrel is made according to paragraph d) of this article:<объем пней и корней в плотной мере (графа 20)> = < плотная мера объема стволов (графа 13)>*<переводной коэффициент (графа 19=0,23)>. The flowing measure volume and roots is adopted in a double volume:<объем пней и корней в складочной мере (графа 21)> =<объем пней и корней в плотной мере (графа 20)>*2.

8) Calculation of the total volume of wood to a divestly:<полный объем (графа 22)> = <объем стволов в плотной мере (графа 13)>+<объем сучьев и ветвей в плотной мере (графа 16)>+< объем пней и корней в плотной мере (графа 20)>;

9) Calculation of the total volume of wood to the query extent (this indicator most objectively allows you to estimate the need for the capacity of the body (containers) of vehicles for the export of irrigation residues):<полный объем древесины в складочной мере (графа 23)> = <складочная мера объема стволов (графа 14)>+ <объем сучьев и ветвей в складочной мере (графа 18)>+ <объем пней и корней в складочной мере (графа 21)>

10) The volumetric weight of wood into a divestly (density in T / m3) is recorded in column 24 according to paragraph B) of this article, for breeds are missing in Table 185 - in accordance with Annex 3 to SNIP II-25-80 (wood density and plywood ).

11) Calculation of the stem weight:<вес стволов (графа 22)> = <объем стволов в плотной мере (графа 13)>*<объемный вес древесины (графа 21)>;

12) Calculation of the weight of the branches and branches:<вес сучьев и ветвей (графа 26)> = <объем сучьев и ветвей в плотной мере (графа 16)>*< объемный вес древесины (графа 24)>;

13) Pumping and root weight calculation:<вес пней и корней (графа 27)> = <объем пней и корней в плотной мере (графа 20)>*< объемный вес древесины (графа 24)>;

14) Total weight of exported waste (carrying residues):<вес вывозимого отхода (графа 28)> = <вес стволов (графа 25)> + <вес сучьев и ветвей (графа 26)>+<вес пней и корней (графа 27)>

Thus, the proposed technique allows you to calculate the volume (both complete and share) and the mass of irrigation residues with differentiation over the type of waste based on the source data of the barded statement, as well as to estimate the required volume of storage bunkers or vehicle bodybuilders and the number of machine flights for Their export.

It makes no sense to produce the same calculations several times if the initial data does not change. A log-rounded diameter of 20 cm and 6 meters long will always have the same volume, despite the one who is counting in which city. Only the formula V \u003d πr²l gives the correct answer.

How to calculate the cube of the forest

Therefore, the volume of one OCB will always be v \u003d 3.14 × (0.1) ² × 6 \u003d 0.1884 m³. In practice, to eliminate the moment of standard computing, cabbage applies. Such useful and informative tables are created for various types of lumber. They help save time and learn the cube of forest-rounding, boards, bruises, timber.

Cubean Round Forest
How to use the table?
Cubature of products of different sizes

What is a cube?

The name of this construction reference book is due to the fact that the volume as a physical value is measured in cubic meters (or cubic meters). For a simpler seizure, the "cube" say, respectively, the table was called "Cubature". This is an ordered matrix into which data is entered on the volume of one product for various initial parameters. The base column holds the sections, and the row is the length (mold) of the material. The user is enough to find the number located in the cell on their intersection.

Consider a specific example - a cube of a round forest. It was approved in 1975, it is called GOST 2708-75, the main parameters - diameter (in cm) and length (in meters). We are very easy to use the table: for example, it is necessary to determine the V single log, having Ø20 cm with a length of 5 m. At the intersection of the corresponding row and column we find the number 0.19 m³. A similar cube for rounding exists according to another standard - ISO 4480-83. References are very detailed in increments of 0.1 m, as well as more general, where the length is taken after 0.5 m.

Small secrets

The use of Cubaturenik does not represent any difficulty, but the main nuance is the correct data. Round forest is not a cylinder, but a truncated cone, from which the bottom and the upper arm are different. One of them can be 26 cm, and the other - 18. The table involves an unambiguous answer for a specific section.

Various sources are proposed to come in two ways: carry out the calculation of the average value and take the amount from the directory for it or as the main section to take the size of the upper heap. But if the tables were compiled according to certain standards, then it is necessary to use them according to related instructions. For cube, GOST 2708-75, the diameter of the top sleeve was taken. Why is the moment of source data so important? Because with a length of 5 meters for Ø18 cm we obtain 0.156 m³, and for Ø26 cm - 0.32 m³, which is actually 2 times more.

Another nuance is the right cabbage. If the complex formulas for truncated cones were used in the GOST 2708-75 table, calculations were performed, and the results were rounded to thousandths, then modern companies that make up their own cubeats, allow themselves to "liberty". For example, instead of 0.156 m³ already costs the number 0.16 m³. Often, frankly erroneous cabins are placed on the Internet on the Internet, in which the volume of the log 5 meters long at Ø18 cm is not 0.156 m³, and 0.165 m³. If the company uses such reference books, implementing a round forest to consumers, then it makes a profit, actually deceiving customers.

After all, the difference on 1 product is essential: 0,165-0,156 \u003d 0.009 or almost 0.01 m³.

The main problem of forest-rounding is a different cross section. Solve issues with calculations, sellers are offered in such ways:

calculating the volume of each unit and summation of the obtained values;
storage method;
finding the average diameter;
a method based on wood density.

Immediately need to say that the correct results give the first of these options. Only the calculation of the volume of each log and the subsequent addition of numbers ensures that the buyer will pay for the forest that he will receive from the company. If the length is the same, it is sufficient to find the area of \u200b\u200bthe sections of all trunks, fold them, and then multiply the length (in meters).

2. Warehousing method.

It is assumed that the steady rounder occupies part of the space having the shape of a rectangular parallelepiped. In this case, the total volume is found multiplying the length, widths and height of the figure. Considering that there are emptiness between the folded trunks, 20% will take away from the cubature.

Minus - adoption as an indisputable fact that the tree takes 80% of the total space. After all, it may well happen that the bars are folded inactively, thereby the percentage of emptiness is much more.

3. A method based on density.

In this case, you need to know the mass of the forest and the density of the wood. The cubature is easily divided by the first number to the second. But the result will be very inaccurate, since the tree of one species has a different density. The indicator depends on the degree of maturity and humidity.

4. Averaged method.

If the trunks of the harvested trees on the appearance are almost the same, then you choose any 3 of them. Measure diameters, and then find the average value. Next, in the cube, the parameter for 1 product is determined and multiplied by the desired amount. Let the results showed: 25, 27, 26 cm, then Ø26 cm is considered to be average, since (25 + 26 + 27) / 3 \u003d 26 cm.

Considering the disadvantages of the considered methods, the only correct method of calculating the cubature can be considered to be the foundation of each log using the Kubatournik GOST 2708-75 or ISO 4480-83 and summing the data obtained.

Calculation of lumber cube - Consider correctly

In the process of building structures from wood, various lumber is purchased.

When purchasing or selling it, it is necessary to measure it. The complexity of the timber measurements due to its non-permanent and non-standard size and shape, weight and quality. Plusfully such a product is also impossible to implement because of the factors mentioned above. Make the right one calculation of cabbage lumber Not a specialist is very difficult, moreover, even the controlling authorities are sometimes not able to check whether the calculation is performed correctly.

Some producer lumber are supplied in packages with an indication of exact volume and cost. But this practice is quite rare. In addition, consumers may have doubts about the correctness of the calculation of sawn cubs, as well as about the specified price. The usual buyer does not always know that in addition to the cube, the cost of sawn timber depends on the degree of their treatment, that is, non-edging or edging board, wood species and fortification. In addition, the cost of boards up to 1.7 m long below the cost of longer boards. The quality of timber produced regulates a huge number of rules and rules, technical conditions and other regulatory documents, which individual developers do not even suspect, at the same time sellers of lumber are in no hurry to familiarize their buyers with the rules for selling sawn timber. In order to have at least a general idea of \u200b\u200bhow the lumber cube is calculated, it will not be superfluous with the rules of the measure of some of the most common types of their species.

According to current standards, the hill must be sorted depending on the length into two groups - up to two meters and over two meters. The porch is stacked, alternating thick and subtle ends, as well as a hollow surface. The stacks should be the same height along the entire length, straight angles, to lay them are needed as tight as possible. Then, moving the width, length and height of the package, get a robbery cub.

In the woodworking industry there are the concepts of a share and dense cubic meter. In the price list on lumber are indicated for the volume in dense mass, so the folding cubic meters must be translated into a dense mass. For this, special transfer coefficients are applied. For example, for a hill up to two meters long, a coefficient of 0.48 is used, and for a hill with a length of more than two meters - 0.43.

Determine the volume of lumber of coniferous and hardwood can be in two ways. Either with the help of the measurement of each unit of material, or with the help of a special standard, or a cube, installed by GOST and intended for determining the volume of edged lumber of deciduous and coniferous rocks. The standard has a table of one lumber unit and a meter volume table, repulse from which you can calculate the cost of sawn timber.

When calculating the cabbage of sawn timber, several other rules apply.

How to accurately calculate the log cabin?

The specificity of their measurement lies in the fact that the width of one-sided edged and non-edged board is calculated as half the width of two plastics - narrow and wide, which is measured by the middle of the board. The volume of round timber is calculated based on the measurements of each log. Dense cubic meters of logs are calculated by means of an appropriate GOST, which indicates the volume of round timber. These volumes are measured along the length of the log and the thickness of the upper end.

In our offered, the table is given calculation of lumber cubic: Edged and non-edging boards, floorboard, bar, timber, lining and rails. On the table, you can calculate the amount of sawn timber in the 1st m3.

The purpose of this article to explain to you how to correctly calculate the area of \u200b\u200bthe walls of log houses, baths and other buildings, as well as buildings from glued and challed bar. Many will say - what is there to explain and so everything is clear - you just need to know the basics of geometry.

Cubature of Round Forest - how to calculate the volume?

Completely - without geometry, it is not necessary to do without geometry, but this measurement has its own feature, unlike walls from a bar and other materials, but about it below.

For what you need to know how the log cabin is calculated:

it will help more accurately calculate the cost and amount of the required material *
calculate yourself Cost of work on painting and grinding of log cabins

To calculate the walls of the walls, we all know that you should know two magnitudes, height and length, and for complete calculation and the area of \u200b\u200bthe ends
S \u003d PI * R2 - Area 1 Circle (end) ,Where
P. — 3,1428
R. - Radius of the end
Knowing the area of \u200b\u200bone end, we multiply this amount by the number of ends and get the total area of \u200b\u200bthe eases.
The main feature of the log structures is that the logs have a convex form, so the height is measured as usual - from the floor to the ceiling will differ from the actual 10-15%.

Calculate the area.

What would measure the height of one logs you just need to take the roulette and postpone it from the top seam to the lower seam of the crown as shown on photo №1(To measure the height of a chopped log cabin, the average value is taken). And the bar need to measure the width of the edges and fold with the value BUT (arrows are shown on photo №2.). We will get a real height of one log or bar, and knowing the number of crowns - we will get the real height of the wall (the columns of the crowns * the height of one crown). Remind the formula of the area of \u200b\u200bthe rectangle I think to me that you do. So everything is simple.

So having folded all the data - the area of \u200b\u200bthe walls, "triangles", the ends and from the amount received, to take away the area of \u200b\u200bthe window and doorways - we will get a complete area of \u200b\u200bthe structure and already on the basis of these data we can independently determine (knowing the price of work per M2) the cost of work, materials *, As well as their volume * (transferring them to the company manager by phone or arriving in the office) **.

Finally, the ladies of a small advice, if the mismatch of the structure of a simple form, everything is simple and will not be much labor and will not require a lot of time, but what about complex forms, such as photo number 4..

I will say directly - measure yourself or attend when measurements when you make your employees, these most you will avoid deception from unscrupulous construction teams or refer to the proven companies.

* The cost and volume of the required material (coating) affects the state of wood (polished, not polished) and the coating method (brush, roller, sprayer)

** For your convenience, on our website, the cost of materials is calculated on 1m2
