How many bars 180x180 are in a cube and why is it needed?

If you have experience in the purchase of timber, then you are well aware that the calculation of the cost of products is based on the cost of a cube. We will not judge whether it is rational or irrational, just analyze how much a 180x180 bar is in a cube and what it is for. Calculated and comparative data, and this instruction will be devoted today.

Who is this timber, where did it come from

It is difficult to say definitely who had the idea to use a bar with a section of 180x180 for the construction of residential buildings. Such a prospect is possible only for the southern regions, where the forests are not very thick and the wood products are more expensive, and they are not used as often.

But for the sake of comparison, let's weigh the pros and cons:

• Everyone has long known that the minimum section size of a timber that does not require insulation and withstands seasonal temperature fluctuations in the temperature range of 80 degrees Celsius - 200 by 200 mm, can be 200 by 100 or 150 mm, but the width of the rim must be 20 cm. 180x180 mm requires warming, even in the middle climate zone, not to mention the northern regions, where wider corridors of seasonal temperatures are possible;
• A 180 mm timber will certainly be lighter than a 200 mm equivalent and for its construction it can be confined to a pile foundation to the level of soil freezing. At the same time, it does not matter at all whether a one-story house or a two-story house is built, there are enough piles;
• Questions of environmental friendliness, strength, "breathing" we obviously omit, in these categories all natural products are the same. This also includes beams made from the same type of wood. Agree stupidly to argue about the advantages or disadvantages of beams made of larch or pine - the price will tell everything;
• And by the way, the question of the cost of timber, we can not tell you definitely that it will be cheaper to bar 200 to 200 without insulation or timber 180x180 with insulation, because we don’t know what kind of insulation you will use and what material to veneer your house, we can only advise one practical cunning.

Tip! If you are attracted by the relative cheapness of the material, and you are going over time to conduct the warming of the log house and brick facing, then you will not escape the solid monolithic foundation anyway, and this, by the way, is a significant weighting for the whole construction.

You are lucky in the sense that this article is not commercial in nature and does not carry a hidden or explicit advertising, so the material is treated as is, without ties.

The settlement account, the settlement account

It is not strange, but in the abracadabra that you read, it makes sense, and to be perfectly accurate, then a summary of the entire chapter. The cost of the material is calculated per cubic meter of products, and the price of a certain number of products is calculated in multiples based on the stated price of the cube.

Therefore, before you pay for the material, you must at least have an idea of ​​how much 180x180 mm in 1 cube of a beam, and only then, knowing how much a cube of a beam costs 180 by 180 mm, calculate all the construction costs. Therefore, we offer you the magic of practice in action.

So:

• Calculate how much timber in a cube is 180 by 180 mm. To do this, you have to remember the course of mathematics, where the concept of volume first appeared. And having made simple calculations, you can easily determine the volume of one beam (remember, the length multiplied by the width and height gives the volume of the bar). After this, dividing the unit (as a volumetric value) by the resulting initial volume of the beam, you get the number of objects in the cube of the material;

Additional Information! In order not to overload the material with mathematical calculations, calculations and other "delights" we offer you ready-made solutions for simple calculations. The most popular beams are 6 and 4 meters. The amount of timber in a cube in the first case will be 5.1 pieces, in the second, 7.7 pieces. Of course, the tenths in the calculations of one cube look ridiculous, but then not 5 and not 10 will go to the house, but the tenths are much more useful, and even the hundredths can play their part. Well, as a dessert - 2 meter beams in a cube, this is 15.4 pieces.

• It is much more interesting and difficult to answer the question if there is a 180x180 beam - how many pieces are in a cube, if the dimensions of the beams are different. So that we are not accused of phantasmagoria, look at the attic walls, you do not need full-length beams of 6 meters in length for the whole front of work.

You can get by with smaller beams, and even if you decided to build a small bath, why should you buy 6-7 meter beams, if 4 meter be able to cope with the tasks assigned to them.

In this case, you are offered two solutions to the problem:

• Calculate the number of all beams and derive the arithmetic average length;
• Carry out the calculation for each type of beams separately.
• From size to cost. How much does a bar 180 to 180 mm turn out to be not at all idle, the fact is that the same timber from the same wood, the same characteristics can have a difference in the price of 1.5 times and even a little more.

The official version is a dry log or profiled bar of natural moisture. Unfortunately, what started beautifully does not always have a beautiful continuation, so the advice is practical.

Note! Planed timber, which passes as dry or chamber-dried, is often, at best, material dried under a canopy, but not a fact. It could be svezhespilenogo beams, which almost from the logging cut into beams and thrown into the market. Therefore, in this case, there are also two options, or you can trust in the good name of suppliers and manufacturers, or take a moisture meter with you. Especially since the rate of 20% from 80% you always distinguish. And one more thing, take a roulette with you, just in case, because under the guise of a bar 200 by 200 often sell a bar 195 by 195 mm and even 190 for 190, and under the guise of a bar 180 by 180 mm, they may well bring smaller analog.

About the construction of literally a bit

This chapter does not set a goal to disclose all the technology of building a house from the above bar.

Here are some practical observations that may be useful to you:

• A house of 180x180 mm is considered light, we have already voiced the problem of foundations, we will not repeat, we will talk about the choice of material. The simplest material is profiled timber; it allows you to assemble a house very quickly and practically with your own hands. By the way, the price of this material will be 1.5, two times lower than the glued analog;
• Keep in mind that if you use a square beam, then you are not insured against cracks in the solid wood beam, there are two ways out again: either take the product not square, but rectangular, or make an additional unloading groove in the beam itself;

• Remember the most important thing: in the first year the building is not insulated; this is due to the shrinkage of the material, so if, despite all the good advice, you were able to endure the year before, be prepared for the fact that you will be provided with church air in winter.

Finally

Calculations are important, calculations are needed. The simplest to order a project at home in a company that earns money is somewhat more difficult, but it is cheaper to carry it all out yourself, and then courageously overcome all the burdens, well, then you know (at least make a calculation on the foundation). The video in this article has prepared a review of the topic.
