With the industrial billet of the round forest, it is rather difficult to determine its cube. To accurately calculate the volume of each log, you can use the formula of a truncated cone, where the main diameters of both sleeps and the length of the log itself are taken into account.

Round forest is very convenient and practical to build houses, baths and other residential and non-residential premises.

In fact, in such a difficult way, the cubic size of the round forest is not calculated. It is accepted in a faster way around the world. Special tables are used for this.

How to calculate the cabbage of a single tree without additional measurements?

A few years ago, a product of the middle arithmetic spikes on the length of the tree was used to calculate the volume of single tree. With the help of the meter (reminds of the usual caliper), the diameter of the tree was determined in the middle part of it. Then it was multiplied by 3 and the cross section was obtained.

Further, the obtained number was multiplied by the length of the workpiece, and the volume result was obtained. This method of calculation is inaccurate, since the thickness of the bark is not taken into account. The number Pi was taken with a large deviation from real, and the formula in the distorted form was given great errors.

The formula itself looks like this: the diameter of the rounded log is divided into 2 and is built into the square, then multiplied by the number of pi and on the length of the log.

Even if the thickness of the cortex is measured and take into account this to determine the diameter of the tree, the deviations from these indicators will be inaccurate, although with a smaller error. More accurate calculations showed that actual deviations in the calculations of the cube of a round log at primitive measurements have a definite dependence on the tree parameters, which was taken into account when compiling the corresponding tables to determine the volume parameter. Let's try to figure out how to calculate the forest cube. This will require:

• roulette;
• relevant design tables, where there is a finite cubic.

How much will weigh the cube board?

Technology of calculating the volume log

First, it is necessary using a roulette to make meat the length of the tree and its diameter on the heap at the top (excluding the bark). After that, look at the tabletastes: at the intersection of the line, where the length of the tree is indicated, and the column, with an indication of the corresponding diameter, we find the volume of the measured body. Everything is simple and secure.

Such calculations should also be called absolutely accurate, since the features in which the forest was grown, and the shape of the barrel were not taken into account. But on such trifles for large volumes of the workpiece, it is customary not to pay attention.

Calculation of the scope of the stored forest

With industrial volumes of round logs, other techniques and tabular data are used. In essence, the round forest array in the stored state has the shape of a rectangular parallelepiped. Calculations of its volume are familiar with everyone from school bench. But it is impossible to use this method, since the dimensions of the emptiness between the logs will not be taken into account. By the way, they, too, directly depend on the diameter of logs, which are amenable to mathematical calculation.

By numerous calculations, the coefficient was determined by which a special table was compiled. It works similarly to the previously described table, with the only difference that the volume of said parallelepiped is taken into account and the average thickness of the upper cut. Forest cube calculates with great accuracy.

But it is impossible to hope for good accuracy of calculations with an inaccier stacking of forest products. Such a procedure is not used in the warehouse storage of the forest, as in this case the volume is estimated that the round forest occupies directly in the warehouse.

Calculate the cube is very easy after the preliminary weighing of the forest.

Next, it is necessary to calculate the volume by dividing the mass of the forest to the density that corresponds to the type of wood. Such a calculation also cannot be considered ideal, since the forest in different degrees of maturity has a deviation in density. Humidity of wood can play a special role here.

When the billet of the round forest is performed, first of all try to accurately calculate its cube.

Measurement is performed in the upper cut, where the diameter will be slightly less. When measuring the trunks that have a cross section, different from the round, try to make measurements by the narrow cross section, passing through the center of annual rings of wood.

This technique is used because it allows you to most accurately estimate how edged lumber from one logs, having the greatest value in woodworking. Obviously, they will do them, based on the diameter of the upper cut.

For the same reason, the grinding part of the trunk, where the difference between large and smaller cuts is large, prefer to discard and do not use in the workpiece. Anyway to take on the sawmill there will be a forest on the top cut.

When determining the length, measurements are made with an accuracy of up to 10 cm, while the length is rounded to a smaller side. Such accuracy is made due to the fact that with a roll of logs, they usually make two inscribed - one above, the other below. First they make the bottom, then the upper - on the other hand. Falls in the other side where his macushkin tends. The propyls make that the bottom was from the other side where the trunk should fall.

At the same time, the upper propyl is done on the other hand, standing in the direction opposite to the most likely drop. During the subsequent sawing, the whip is usually diverting with a saw on one propyl, however, often the error of the cut is allowed - it can take place a little oblique, because of this such a big error.

Calculation by cabinets

In accordance with it, it is possible to determine the volume of each log, performing measurements and pick up the value on the table. In the table, the diameter of the trunk is increments of 1-2 cm, and the length of 10 cm. Of course, it is not entirely convenient to use the entire table of the bubble.

This table shows the data for the most common diameters of the upper cut and lengths. It is usually required to consider the volume for a log length of up to 6 meters. It is the brica of such a length that the majority of the standard bodies of ordinary, non-specialized as timber trucks or timber trailers for tractors, it is in size up to 6 meters a squabble of whips.

Naturally, when the forest is handed over to the pilor, it does not go about any "approximate" calculations, and it is necessary to apply the full GOST with the final calculation - because it is the sawmills, and the depths of forests who love the accurate count.

Calculation of the formula

V \u003d πd²l / 4, where D is the diameter of the barrel in the upper cut, L is the length of the log, π \u003d 3.14 - for our calculations, the big accuracy of this constant is not needed.

It is convenient when not at hand is the GOST, but there is only. With large volumes of work, even from three or four cars, there will be a lot of time to calculate this way, in addition, this technique is not standardized and is not in the argument in financial disputes.

Here is the table in which the cube of the round forest is indicated depending on the diameter of the log. These calculations are given in accordance with GOST 2708-75, which is valid on the territory of the Russian Federation since 1975. The table allows you to calculate how many round wood cubes will need to build a log from the manufacturer.

Standard log length, which are used for the construction of log cabins is 6 meters. Billets of this length are used most often. The logs, the length of which is more than 6 meters, is used to produce hand-held houses very rarely.

Most often, the architect optimizes the cutting card on the map in such a way as to avoid (or minimize) the use of long runs. Circusted logs over 6 meters is technically impossible.

Below in the table shows a cube of a round forest, and for your convenience, we have highlighted a column of 6 meter blanks.

How is the cube of a wooden house with a preliminary calculation?

First you need to calculate how many billets are necessary for the construction of the house from the log. In the finished projects from the "Alphabet of the Forest", this information is contained in the section "Calling Cards". The photo below presents summary information for the construction of software.

This is the data for a pinned log with a diameter of 240 mm and 6 meters long. We see on the cutting map that, for construction, we need 547 blanks, while recalculating cubic meters according to the table presented above, 146.71 m3 is obtained. This data is automatically calculated by the "AT - Crowns" program.

A program in which our architects design wooden houses gives an accurate cube without window and doorway, taking into account all the design features of a wooden house. It is almost impossible to achieve such accuracy with manual calculation.

547 * 0.33 \u003d 180.51 m3.

Thus, we obtained the result, taking into account the lunar groove - log, conventionally, is counted as a cylinder, and the program considers less a lunar groove.

This calculation once again proves the importance of a professional project and the presence of carding cards that allow you to accurately calculate the number of logs and lumber and rationally use the construction budget. But for indicative calculations, to understand the order of prices, this method is very informative.

Mathematical method for calculating the cube of a wooden house (with a practical example)

What to do, if you liked the house in the picture, and you do not have a complete project, and even more so cutting cards? In this case, you need to be patient and calculate the length of all log in terms of plan. It should be understood that in this case the error with a real result may be significant, and in both directions.

The task is to calculate how much blanks need to build a house from a log. Standard log length, as we have previously reported to you, often does not exceed 6 meters. It is very important at this stage to decide on the height of the floors! And according to this, calculate the number of crowns.

For this, we need a log profile height table depending on the diameter. It is presented below. We consider the length of all the crowns (logs), including the frontones, and divide the resulting number to 6.

Round log profile height

Log diameter, mm	Height of the crown, m	The height of the crown, mm
220	0,1905	190,5
240	0,2078	207,8
260	0,2252	225,2
280	0,2425	242,5
300	0,2598	259,8
320	0,2771	277,1
340	0,2944	294,4
360	0,3225	322,5
380	0,3399	339,9
400	0,3572	357,2

EXAMPLE:

Suppose we want to build a house of a chopped log with a diameter of 320 mm. One full-fledged floor, the second floor is attic. The desired height of the first floor after shrinkage - 3100 mm, the desired height of the attic at the wall - 1500 mm. The height of one crown at a diameter of 320 mm is 0.2771 mm.

Important! The average height of the first floor of any cut to the shrinkage is 3.2 m, the height of the attic wall in the attic on average is 1.5-1.7 m. After shrinkage, the height of the walls will decrease by about 7-10%, so it must be taken into account when initial calculations . It is also necessary to take into account the composition of the floor of the first and second floors. A competent architect will always tell you how to do it right.

So, in our example:

• First floor before shrinkage: 12 crowns, which will be equal to 3.33 m.
• Attic wall in the attic before shrinkage: 6 crowns, which is 1.66 m.

Now we need the length of the walls of each floor. To do this, it is necessary to calculate the perimeter of all walls (carriers and internal) according to plan.

Suppose that the length of the first floor we have 100 meters of the route, and the length of the attic floor was 85 mp.This is the result without deducting window and doorways. If you need a more accurate number, then you need to calculate all openings in length and height and subtract out of the total.

We will consider a more simplified version of the calculation of the cube house from the log from the manufacturer.

So,

• First floor 100 m * 12 crowns \u003d 1200 mp
• Mansard floor 85 m * 6 crowns \u003d 510 mp.

So, the total length of the walls: 1200 + 510 \u003d 1710 mp.

Thus, we received the total length of the walls only, without taking into account the frontones, balconies, terraces, vertical support pillars, chopped farms and other elements that can enter the project at home.

Important! It is necessary to add 5% to the resulting cube result, which will come in curly editions of logs and skate logs. The exact number depends on the diameter of the log, the cutting method. For approximate calculations, it is limited to 5%.

So, we divide the resulting length of 6 meters and we get 1718/6 \u003d 286.33 pcs. Thus, 287 blanks will be required to build walls in our fire. We multiply this number by 0.59 (data from the "Round Forest Cabing Calculation Table") and get169.33 m3.

To the resulting cube we need to add frontones. They are in the most simple case 2, they are triangular. The area of \u200b\u200b2 triangles will be approximately equal to the rectangle area. Therefore, we consider the length of one wall, where the frontoth. We multiply on the number of crowns and get the length of the log in both fronts. The result is divided by 6.

Important! The sum of the crowns of attic and the frontones is equal to the height of the first floor. Therefore, if we have the number of crowns of the first floor equal to 12, and in the attic - 6 crowns, then there will be 6 crowns in the front (12-6 \u003d 6).

Suppose that the length of the front is equal to 11 meters, the crowns we have 6. So, 11 * 6 \u003d 66 m. We divide on 6, we get 11 pieces. 11 * 0.59 \u003d 6.49 m3

Thus, the cubature of our house from a log of 320 mm with a diameter of 320 mm is 169.33 + 6.49 \u003d 175.82 m3. When rounding received 176 m3.

It was possible to go from the opposite, first consider the number of all blanks, and then translate into cubic meters. Check our result in this way:

287 (blanks for walls) + 11 (billets for frontones) \u003d 298 * 0.59 \u003d 175.82 m3, rounded, 176 m3.

That is, everything is counted right.

Important! Do not forget that this is not the final result. It is necessary to study the sketch and if there are terraces, balconies and vertical poles, they must be added to the total number. We consider it manually, because We have a calculation with you - mathematical. For example, if there are pillars, then each pillar is considered for one 6 meter blank of the desired diameter. We also consider a fence for the terrace, passages, chopped farms and other elements.

Now you know how to calculate the cabbage of the chopped house or house from the rounded log. If you do not want to deal with complex calculations yourself, please contact our specialists! We will make a detailed estimate for you. This is a free service and nothing obliges you.
