Log cubature: how to calculate the volume of rounded logs. Wooden houses and baths to order How many diameters a log is 6 meters long

Rounded logs are ideal material for building a bath or country house... Such products are distinguished by environmental friendliness and safety, attractive appearance and quick installation, ease of installation and processing. Due to a special manufacturing technology, the logs acquire a perfectly flat cylindrical shape and smooth surface, the same diameters and dimensions.

Thanks to these parameters, the products are stacked closely, which eliminates the appearance of cracks in the frame. In addition, the construction of a house or a bath is quick and easy. The log structure will look elegant and neat.

10 reasons to build a house out of rounded logs

• Natural and environmentally friendly wood does not emit toxic substances and is safe for humans. Moreover, the tree has healing properties and has a beneficial effect on the well-being and sleep of a person;
• Wood promotes rapid air exchange and renews oxygen up to 30% per day. Therefore, in a wooden house it is always comfortable and easy to breathe;
• Attractive and aesthetic appearance. The log house looks elegant and natural. It will harmoniously fit into any landscape and will stand out favorably against the background of other buildings;
• Due to the special processing of the material on the machines, the logs get a flat and smooth surface. Therefore, the products fit tightly to each other and exclude the appearance of gaps in the walls;
• The same diameters and dimensions of the logs make installation quicker and easier. Depending on the complexity of the project, the installation of a log house will take only 3-5 days to 3-4 weeks !;
• Light weight of wood does not require a massive and expensive foundation;
• Rounded logs do not require decorative finishing neither inside nor outside the building. By the way, finishing “to zero” in a log house looks harmonious and impressive;
• Wood has high heat and sound insulation performance. The log house is warm, quiet and calm;
• With the correct caulking of the log house, there is no need to repeat the procedure. Whereas at home from a bar, you must re-caulk after shrinkage;
• The logs are easy to process, which allows you to create interesting structures (houses with a bay window, carved balconies, verandas in the form of a rotunda, etc.). Moreover, the log house can be built in any style!

How to calculate the volume of materials

For those who decide to build a log house, it is important to correctly calculate the required amount building materials... Since the logs are characterized by a cylindrical shape, it is necessary to carry out the calculation based on this parameter. You cannot calculate the volume by simply multiplying the wall thickness by the height. To correctly do it yourself, use a special round log cubature.

The simplest calculation is carried out according to the formula \u003d P * R2 * N, where

P = 3,14;
R2 - the radius of the rounded logs in a square;
H - the length of the rounded log.

The result is multiplied by the number of logs required to build a house or bath. Do not forget to add 7%, which is allocated for shrinkage. log house... To facilitate the calculation, the results for different log diameters are presented in a table of log cubic capacity.

The volume and cost of materials is influenced not only by the type of wood, but also by the diameter of the log. If you are planning to build a house for permanent residence, choose a size of at least 240 mm, and for the northern regions - more than 260 mm. If it is summer country house for seasonal living and recreation, logs with a diameter of 220 mm are suitable. For the gazebo, you can take the minimum size.

The table is not the only way to calculate the required amount of building materials. There is a special online calculator, which will make a quick and accurate calculation of the quantity and cost of materials, taking into account shrinkage, internal partitions and other factors.

In addition, the calculator will calculate the useful area of \u200b\u200bthe room, the number of crowns and the load on the foundation. As a rule, on the websites of construction companies, each standard project is accompanied by its own calculator.

If you do not know how to correctly calculate the volume of logs, the specialists of the MariSrub company will help you! Experienced craftsmen will select and calculate the volume of materials. Experts recommend choosing rounded pine logs, as this is the best price-quality ratio.

Pine is an affordable sturdy wood that is distinguished by strength and durability, a pleasant coniferous aroma and beautiful texture... Choose your favorite version of the log house or order individual project! Experts will prepare an estimate of the future house or summer cottage for free, calculate the amount of materials and the cost of construction.

This question is the most relevant when it comes to building a house from a log. How to calculate the volume of a house yourself? How to check the declared forest cubes in the estimate from the developer?

Here is a table that shows the cubic capacity round wood depending on the diameter of the log. These calculations are given in accordance with GOST 2708-75, which operates on the territory Russian Federation since 1975. The table allows you to calculate how many cubes of round wood will be required to build a house from a log from a manufacturer.

The standard length of logs used for building log cabins is 6 meters. Billets of this length are used most often. Logs longer than 6 meters are rarely used for the production of hand-cut houses.

Most often, the architect will optimize the log house from the cutting plan in such a way as to avoid (or minimize) the use of lengths. It is technically impossible to produce a rounded log over 6 meters.

The table below shows a cubicle of round wood, and for your convenience, we have made a column of 6-meter blanks highlighted.

How is the cubic capacity of a wooden house calculated in the preliminary calculation?

First you need to calculate how many blanks are needed to build a house from a log. IN finished projects from "ABC FORESTS" this information is contained in the section "Cutting cards". The photo below provides a summary of the construction information.

This data is for a rounded log with a diameter of 240 mm and a length of 6 meters. We see from the cutting map that for construction we need 547 blanks, when converted to cubic Meters according to the table above, this gives 146.71 m3. These data are automatically calculated by the AT - VENTSY program.

The program, in which our architects design wooden houses, gives an accurate cubic capacity without window and door openings, taking into account all design features wooden house. It is almost impossible to achieve such accuracy with manual calculation.

547 * 0.33 \u003d 180.51 m3.

Thus, we got the result taking into account the lunar groove - the log, relatively speaking, is counted as a cylinder, and the program counts minus the lunar groove.

This calculation once again proves the importance of a professional project and the availability of cutting maps, which allow you to very accurately calculate the amount of logs and lumber and rationally use the construction budget. But for approximate calculations, in order to understand the order of prices, this method is very informative.

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

What to do if you liked the house in the picture and you don't have a complete project, let alone a cutting map? In this case, you need to be patient and manually calculate the length of all the logs according to the plan. It must be understood that in this case the error with the actual result can be significant, and in both directions.

The task is to calculate how many blanks are needed to build a house from a log. The standard length of a log, as we have already informed 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.

To do this, we need a table of the height of the log profile depending on the diameter. It is presented below. We calculate the length of all the crowns (logs), including the pediments, and divide the resulting number by 6.

Round log profile height

Log diameter, mm	Crown height, m	Rim height, 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 from a chopped log with a diameter of 320 mm. One full floor, the second floor is an attic. The desired height of the first floor after shrinkage is 3100 mm, the desired height of the attic against the wall is 1500 mm. The height of one crown with a diameter of 320 mm is 0.2771 mm.

Important! The average height of the first floor of any log house before shrinkage is 3.2 m, the height of the attic wall in the attic is on average 1.5-1.7 m.After shrinkage, the height of the walls will decrease by about 7-10%, so this must be taken into account in the 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 correctly.

So in our example:

• Ground 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 (load-bearing and internal) according to the plan.

Suppose that the length of the first floor is 100 linear meters, and the length attic floor amounted to 85 mpThis is the result without deducting window and door openings. If you need a more accurate number, then you need to calculate all the openings in length and height and subtract from the total number.

We will consider a more simplified version of calculating the volume of a house from a log from the manufacturer.

So,

• First floor 100 m * 12 crowns \u003d 1200 m.
• Attic floor 85 m * 6 crowns \u003d 510 lm

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

Thus, we obtained the total length of the walls only, excluding gables, balconies, terraces, vertical support pillars, chopped trusses and other elements that may be included in the house project.

Important! To the resulting cubic capacity, you need to add 5%, which will fall on curly logs and ridge logs. The exact number depends on the diameter of the log, the cutting method. For approximate calculations, we will limit ourselves to 5%.

So, we divide the resulting length by 6 meters and we get 1718/6 \u003d 286.33 pcs. Thus, for the construction of walls in our log house, 287 blanks are required. We multiply this number by 0.59 (data from the "Table for calculating the volume of round timber") and we get169.33 m3.

We need to add pediments to the resulting cubic capacity. In the simplest case there are 2 of them, they are triangular. The area of \u200b\u200b2 triangles will be approximately equal to the area of \u200b\u200bthe rectangle. Therefore, we consider the length of one wall where the pediment is. Multiply by the number of crowns and get the length of the log in both gables. Divide the result by 6.

Important! The sum of the attic crowns and pediments is equal to the height of the first floor. Therefore, if our number of crowns on the first floor is 12, and in the attic there are 6 crowns, then there will be 6 crowns in the pediments (12–6 \u003d 6).

Suppose that the length of the pediment is 11 meters, we have 6 crowns. This means that 11 * 6 \u003d 66 m. Divide by 6, we get 11 pieces. 11 * 0.59 \u003d 6.49 m3

Thus, the cubic capacity of our house made of a log with a diameter of 320 mm is 169.33 + 6.49 \u003d 175.82 m3. When rounding up, 176 m3.

It was possible to go from the opposite, first to count the number of all blanks, and then convert to cubic meters. Let's check our result in this way:

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

That is, everything is calculated correctly.

Important! Remember that this is not the final result yet. It is necessary to study the sketch and if there are terraces, balconies and vertical pillars, they must be added to the total. We calculate it manually, since our calculation is mathematical. For example, if there are pillars, then each pillar is counted as one 6-meter workpiece of the required diameter. We also consider the fence for the terrace, cuttings, chopped trusses and other elements.

For many builders, the topic of calculating the number of logs in a cube is familiar. But for an unprepared person, this may seem not only very distant, but also incomprehensible. And very often there are disagreements between the builders themselves, as well as between the builders and the customer about how many logs should be in the cube.

In order to deal with this problem, a mathematical method is usually used, which in a few minutes can give a clear answer about how many logs are needed for a certain amount of cubic meters.

As a rule, rounded logs are used in the construction of wooden buildings. But this material can vary in size, that is, in length and diameter. It is customary to take centimeters as a unit of measurement. One cubic meter contains one million centimeters. Thus, you first need to decide on the size of the logs.

In order to measure the size of the logs, you need an ordinary centimeter tape. All logs, as a rule, should initially be of the same size, and later, depending on the project, they are cut into the necessary elements.

So, by measuring the size of the log with a tape measure, we get the length and diameter in centimeters. For example, let's try to calculate how many logs are needed for one cubic meter, if the logs are six meters long and their diameter is eighteen centimeters.

To calculate, you need the following formula:

Volume \u003d Pi * Radius * Radius * Length.

Six meters in this case equals six hundred centimeters. Pi is always 3.14. We get the radius by dividing the diameter by two. Thus, the formula with us takes the following form: Volume \u003d 3.14 * (18: 2) * (18: 2) * 600 \u003d 3.14 * 9 * 9 * 600 \u003d 152604 centimeters. To convert to cubic meters, divide the resulting number by one million: 152604: 1,000,000 \u003d 0.1526. This result tells us that one log of this size will take only 0.15 cubic meters.

Now you need to figure out how many logs are in a meter. This is our main task. To do this, we will divide one cubic meter by the result of our calculations - 0.1526. It turns out: Quantity \u003d 1: 0.1526 \u003d 6.55 logs. It turns out that for one cubic meter we need to take about seven logs of a given size.

If we consider logs with a larger diameter, for example, twenty-four centimeters, then the calculation results will be different:

Volume \u003d 3.14 * 12 * 12 * 600 \u003d 271296 cubic centimeters \u003d 0.2713 cubic meters.

This means that in one cubic meter there will be: 1: 0.2713 \u003d 3.69 logs. In this case, there will be less logs in one cubic meter.

To calculate the number of logs in a cubic meter, a very simple formula is used, which allows you to calculate the result in a matter of minutes. For calculations, of course, it is better to arm yourself with a tape measure and a calculator.

From this article you will learn:

In order to calculate the number of logs for a log house, we need to know:
- The dimensions of the log house (take as an example a log house 3 by 6 five walls - two walls 6 meters each, three walls 3 meters each - these are the dimensions at the ends of the logs)
- The height of the log house (in our example, we take the height of 3 meters)
- The diameter of the log from which the felling is planned (in our example, it is 30 cm)

What's next?
- We consider the total length of one crown (in our case, it is, two walls of 6 meters each \u003d 12 meters and three walls of 3 meters \u003d 9 meters, we add up, and we get the total length of one crown 21 meters
- Find out how many crowns there will be in the log house (the number of rows of logs in height) How to do it?
First, we need to find out the working height of one log, we know that the height (diameter) of one log in our example is 30 cm, from this sum we need to subtract 3 cm for the sample of the longitudinal groove (average), and we get the working height of one log \u003d 27 cm .Now we divide 3 meters of the height of the log house by the working height of one log, we get 11 crowns (rows in height)
- We count the number of logs for a felling. How to do it? We take the total length of one crown (row) in our example, it is 21 meters, multiply by the number of crowns, in our example it is 11 pieces. we get 231 meters. This is the total length of all crowns. Now we divide the total length of all the crowns by the length of one log - 6 meters, and we get 38.5 pieces, round up, and we get that for a log house 3 by 6 five-walled, 3 meters high, from a log of 30 diameter, we need 39 pieces

And so, now you and I know that we need 39 logs of the 30th diameter, but how many cubes are these? The table will help us with this - a cubature of round wood, you will find it below the post.

Looking at the table, we saw that in one 6-meter log of the 30th diameter - 0.52 cubic meters (m3)
Now we simply multiply the total number of logs, in our example it is 39 pieces, by the cubic capacity from the table - 0.52 m3 and we get \u003d 20.3 m3

Conclusion: For the construction of a blockhouse 3 by 6 five-walled with a height of 3 meters from a log of 30th diameter, we need 39 logs, with a total cubic capacity of 20.3 m3

Above, we considered a simple and quick way to calculate the number of logs for a log house, but it has one drawback - inaccuracy in the calculation when it comes to complex log cabins, where the remains of 1.2 meters, 1.8 meters, etc. can remain. which have nowhere else to put in a log house, such log cabins are more difficult to count and much longer. Therefore, they can be counted using the above technology, but adding 10-15% for trimming

Calculation of the volume of round timber
Forest volume calculation table: at the intersection of rows and columns, forest volume in m3

Cubature according to GOST 2708-75 for the length of the log L and the diameter of the whips D. Using this table, you can determine the cubic capacity of round timber with a diameter of 14 cm to 48 cm and a length of 1 to 9 meters

How to use the roundwood cubic meter table?

Step 1. Find the diameter of the log you need in the leftmost row of this table.
IMPORTANT! The diameter of the log is measured at the crown, i.e. smallest

Step 3. Multiply the cubic capacity of the log by the quantity, and you get the cubic capacity of one diameter

Step 4. Add up all the sums of the cubature of each diameter, so you find out the total volume of the round
the woods

Example: A total of 50 pieces of 6 meter long logs have been loaded

1) We measure the diameter of each log and determine the number of logs of each diameter, it turned out:
- 15 pieces - 20 cm
- 10 pieces - 22 cm
- 20 pieces - 24 cm
- 5 pieces - 26 cm

2) We look at the cubic capacity of one log of each diameter in the table, taking into account the length of the log, we get:
- 20 cm - 0.23 m3
- 22 cm - 0.28 m3
- 24 cm - 0.33 m3
- 26 cm - 0.39 m3

3) We count the cubic capacity of each diameter by multiplying the number of logs of one diameter by the indicator from the table for calculating the cubic capacity of round wood (the table shows the volume of the 1st log) It turned out:
- 20 cm (0.23 m3) * 15 pcs \u003d 3.45 m3
- 22 cm (0.28 m3) * 10 pcs \u003d 2.8 m3
- 24 cm (0.33 m3) * 20 pcs \u003d 6.6 m3
- 26 cm (0.39 m3) * 5 pcs \u003d 1.95 m3

4) We consider the total cubic capacity of all logs by adding up the cubic capacity of each individual diameter, happened:
20 cm (3.45 m3) + 22 cm (2.8 m3) + 24 cm (6.6 m3) + 26 cm (1.95 m3) \u003d 14.8 m3 - the total volume of round wood according to GOST 2708-75

It should be added that some roundwood suppliers do not count the diameters individually, but multiply the average diameter by the total amount of roundwood .....
