Rules for calculating the consumption of timber on the house

The use of timber as a building material for the house has a lot of positive things. This product is environmentally friendly, affordable and, accordingly, the most popular. Only it is worth considering that the construction of a wooden house requires advance preparation and a carefully calculated estimate. After all, a well-thought-out plan will allow you to distribute expenses evenly and prevent unnecessary costs.

Special features

When choosing a timber as a building material, you need to remember that it has several types, each of which has its own distinctive properties. The tree of 140x140 mm is considered the most acceptable. And also timber can be of natural moisture, profiled and glued.The first option is the most common, as its cost is significantly lower than the rest. It is quite durable and has a beautiful appearance that does not require additional finishing work.

The profiled type of timber is more hermetic. A house of such material does not need additional warming, as it is rather tightly fixed during installation. Shrinkage is about 5%. Its reduction can be achieved due to horizontal internal kerf timber. The final fastening of the bars between each other is ensured by the system of connection of the thorn-groove crowns.

Many owners of wooden houses understand how important this parameter is. The amount of shrinkage depends on many indicators: the time of cutting wood, climate, construction time and technology of laying. In planed and facing logs, shrinkage is more than 10%. Therefore, timber in this case has its positive sides.

The glued look is quite expensive, due to the fact that there is almost no shrinkage. This advantage allows you to start operating the building immediately after construction.

When the house is completed from a log house, you should give it some time to stand.Do not immediately do the cutting of openings for future windows and doors. It is necessary to wait for shrinkage. Only after the box has stood, it is possible to cut openings through the crown. For even shrinkage, the walls are assembled on wooden dowel pins that prevent horizontal torsion of the beam. And also “winter” wood is more suitable for building a house, since it is drier. Consequently, shrinkage is affected by the time factor when the tree was cut down.

As stated earlier, glued and dry planed timber does not need a “rest” after construction. The percentage of shrinkage in such species is either insignificant or not at all. Only here and the cost of such a timber exceeds by 20-60% of the profiled version. If, however, gaps appear in the walls between the joints, then these places need to be dug, for example, with moss or jute felt.

Just do not worry. The appearance of cracks is a normal and natural process that must be considered when building a house and choosing a certain type of timber for it.

Cubature of 100 square meters or 120 square meters. m can be calculated independently, given the recommendations of experts.It should be that there was a formula for calculating cubes, to know the weight of the material and how much the beam goes to build a house, for example, with a cross section of 200x200 mm.

Projects

Drawing up a project of the future house will allow you to know exactly what the house will be like, what material and where it will be used and, most importantly, how the cost estimates will be made. Preliminary preparation will save not only the budget, but also the time spent on construction. The project should take into account the size of the house, the number of rooms and their area, the number of floors, the presence of additional buildings adjacent to the main housing. And also you need to specify the location of the window and door openings.

To calculate the size, remember that the length of the beam is 6 meters. If the wall of the house exceeds this number, you will have to join the beams.

All these difficulties can stop the entire construction process. Therefore, If you are not sure that you can fully cope with all the work yourself, you should contact a specialist. In this case, although you will need to overpay, but the costs will be justified.

Before building the foundation, you need to dig a trench 70 cm deep, and the width will depend on the number of floors.Standard values ​​are 40–50 cm.

Next, you need to make a mixture of gravel and sand, which is placed in trenches. After completing all these points, formwork is installed in 1 meter. Only then can you pour concrete, the proportions of the components of which will be determined by personal preference. A more liquid mass is suitable only if there are no slots in the formwork.

The construction of the walls is the laying of bars in rows. The first harness should be carefully treated with an antiseptic.

All crowns are fastened every 1.5 m with special nails 6x200 mm in size or else they are called pins, to prevent horizontal twisting of the bars when the tree dries. Thereby, the shrinkage of the walls can be reduced. Locate dowels should be staggered, and cut in the corners of a vertical sample.

The roof usually consists of a supporting structure and the roof of metal. For strengthening use crate. During the construction of the roof, the first step is to make an upper crown tie with a bar with a section of 5x15 cm. Then you can install truss legs from 100x40 mm boards with an interval of about one meter between them. For the fronts, boards with a section of 25x150 mm are used, then the installation of the batten is going on.

If the roof is made of soft material, then you need to cover it in two layers to better protect the house from moisture. If the project provides for an attic that will be used as living space, then you will need to purchase thermal insulation and install it before the final installation of the roof.

House of bars has its own distinctive features. This applies to the very type of tree, taking into account its size and characteristics. Therefore, the preparation and writing of the project should be approached, having familiarized with all the nuances, so that at the initial stages of construction there would be no difficulties. A frame, two-storey house with an attic can be 8x8, 9x9, 9x7, 10x10, 6x9 or 9 per 10 m.

How to calculate?

Building a house is a rather complicated process, but worth it. After all, the result will be their own suburban housing, which can be located near the forest or lake. This will allow at least several times a year to live in the fresh air or even move to permanent residence. In fact, it sounds great to be inspired to build your house. Only now, many make the same mistake during the construction of housing, which can lead to the freezing of the whole process.

Wrong calculations - this is the main enemy in the construction. Any extra figure in project drawings or estimates can lead to serious consequences. Therefore, it is worth paying special attention to the correct calculation of all sizes and the required amount of building materials. All measurements, as a rule, depend on the following factors:

  • the type of timber used;
  • number of bars;
  • the number of bars in 1 cubic meter;
  • what project is used at home.

To calculate the amount of timber in 1 cubic meter, the simplest method of counting is used. To do this, calculate the perimeter of the house, multiplied by the height. Then the result is multiplied by the thickness of the material. The total is the amount you need to purchase. Only it is worth considering that cutting down door and window openings will significantly reduce the amount of timber. Therefore, the total need to add 20%. This allows you to get the final result. For interior walls, the calculation method will be the same.

The first crown is much thicker than the others. For him, calculations are made separately.

After receiving data on the number of required timber per 1 cubic meter, you can find out how many pieces you need to buy. It is not necessary to calculate the volume of the product directly in the store with a tape measure.The thickness and height of each beam may vary, so you should decide in advance what size is needed. The thickness can vary in a given range, namely:

  • 100x100 mm;
  • 100x150 mm;
  • 150x150 mm;
  • 150x200 mm;
  • 200x200 mm.

Height depends on intervening seams. The fewer, the faster the construction work. As for the width, this indicator is more important. Especially when building a house for permanent residence, for which a 200 mm thick timber will be suitable. Products of different thicknesses and widths differ from each other, and it is extremely rash to acquire bars of unequal sizes. Studying all the nuances is extremely important. Thereby it is possible to save money and not to become a victim of an unfair seller of lumber.

All calculations must be made at the stage of project development. Studying the prepared drawings, it will be known how much and what material is needed. If you feel incompetence in this matter, then you should contact the construction companies or read the information on specialized sites. On the Internet you can also find ready-made projects with all sizes and quantities of the necessary materials.

Tips

Everyone wants to do something with their own hands.Such work brings more pleasure. And to build a house yourself is really a great achievement and the result of the huge work done. Timber is a very good building material. It is good for health and absolutely safe. Wood, unlike other materials, does not contain harmful impurities and has a positive effect on human well-being. For example, it can maintain an optimal rate of humidity in a room.

For the manufacture of timber take a whole tree and cut out rectangular beams.

Conifers are best suited as the strongest and most durable material. In addition, the resin prevents the product from rotting very well.

Yet even such a high-quality and natural material has its drawbacks. It requires constant impregnation, protecting the wood from the process of decay. The next minus is the high cost, especially for a laminated timber. If the material is not properly dried, its quality will significantly deteriorate.

Advantages and disadvantages allow you to competently approach the choice of building material from wood, calculate all the nuances and be fully prepared before the start of construction.To do this, you can use the information from the Internet, and make all calculations in an online calculator. On a special online calculation site, you need to enter all the numbers and click on a few buttons. The calculator, based on the entered parameters, will calculate the quantity of timber that is necessary for building a house.

And also it is worth sticking to a few tips regarding choosing the right size of timber, such as:

  • 100x100 mm usually used for the construction of a small room as a bath or a summer house;
  • 150x150 mm more suitable for a full-fledged apartment building;
  • 200x200 mm suitable for building large cottages.

To the recommendations can be attributed a few items. If necessary, you can order the desired size of timber from the seller. The glued type of timber is more durable, which justifies the overestimated cost. Solid timber is almost two times cheaper. This is because the whole process of its manufacture is easier.

      Profiled timber perfectly retains all the useful properties and is in the first place in terms of environmental friendliness among other types of products. When building a wooden house, not intended for permanent residence, such a parameter as the thickness does not matter.For year-round housing will require additional warming walls. The last recommendation is that you should not buy ready-made projects.

      On the Internet, you can get on scammers who know how to sell their goods beautifully. This is especially true of the construction industry. Funers earn well on the illiteracy of people. You should trust only live reviews and trusted sites.
