Among the building materials for the construction of wooden structures, a minibus occupies a special place. High environmental performance, ease of use in a short time made the material popular.
The minibus is a wooden blank adapted to the profile of a conventional building bar, but a reduced copy of it.
Production
Although the minibus is a good material for eco-construction, it still remains little known for a wide range. However, among professional builders it has been quite actively used for over 20 years.
Manufacturing steps:
- According to all quality criteria, a mini-bar can be called a product carved from solid wood. Most often, prefabricated boards with a thickness of about 50 millimeters are used for production.
- The manufacture of small bars begins directly with the sawing of tree trunks. To obtain a truly durable and wear-resistant material for building a house, only high-quality wood is selected. Minibus is most often made from coniferous species.
- Drying of wood for the bars begins at the harvesting stage. Immediately after cutting the trunk into the appropriate parts, the boards for the production of minibus are sent to the dryer. Pre-drying increases the production time, but allows you to minimize possible inaccuracies in size at the stage of final drying.
- The minibus is adjusted to the profile on four-sided milling machines. As a result of turning, characteristic grooves appear, which ensure the convenience of joining and the absence of even minimal gaps between the fixed bars. Small dimensions of the profiled material allow you to customize them with a high level of accuracy, which is convenient during the construction of the house.
- At the last stage of production, the minibus lends itself to final drying. Immediately after milling, the material is sent to a drying chamber, where the moisture content of the wood is reduced to 12-14%.
Some manufacturers do more thorough drying up to 8%. These bars are better suited for the construction of houses, buildings that will be operated in high humidity.
The consumer gets the opportunity to purchase a profiled, small-sized and convenient in construction timber with high dryness.
Dimensions
The minibus is produced by many companies, its dimensions are set by the manufacturers themselves. Standard or classic can be called a material with a width of 145 mm and a thickness of 45 mm. However, not all comply with such parameters. The width remains unchanged (with rare exceptions, a board from 130 to 145 mm can be found), the thickness of the material is from 38 to 48 mm.
In construction, this does not play any role, but when selecting several batches, it is important to know the exact dimensions of the bar in order to choose the right board. Speaking about the length of the minibus, you can refer to the technological norms of its use. It is believed that the length of the wall erected from such a material should not exceed 6 m. Some manufacturers still make exceptions and produce custom materials with different lengths of boards.
Material Cost Overview
The dimensions of the board do not affect the price of the product. The minibus is produced from high quality wood, which means the highest grade grading. Another nuance is the type of wood. All manufacturers prefer to work with the most affordable material, and most often they are raw materials from coniferous trees. There are no too big differences in the price of a bar from this or that manufacturer. The minibus acquires fluctuations in the market value only due to transportation to the point of sale and the nuances that are inherent in local building materials stores.
Due to the fact that the construction often requires bars of various lengths, the measurement during the sale takes place in cubic meters. Cost 1 m3 may be from 15.5 to 16.4 thousand rubles. Building a house using materials from eco-wood is a rather costly project, and the construction of a minibus is the least expensive.
Many companies offer the construction of buildings according to standard designs. Their advantage is quick installation on the site. Sometimes it takes only one day to build. In the case of ordering finished houses, the cost will be calculated depending on the area. For small buildings like a summer house, an area of about 4 m2 will have to pay about 60 thousand rubles. Cost may vary, depending on the price of related materials.
Application
A large amount of minibus is often bought up by companies that are engaged in the direct production of ready-made houses. Such blanks resemble a large wooden designer. It will take a lot of time to independently prepare the material. Difficult in execution is an accurate cut for connecting boards in the corners of the house. To implement the plan you will need a special machine.
Houses are bought in the form of sets (house kits). It is quite easy to assemble a prepared timber, and even people with minimal experience can do it. The detailed instructions that come with the kit help. Three benefits of building a house for factory projects:
- The completeness of the kit. Manufacturers of finished houses from minibars always complete the set with materials that are needed for the installation of load-bearing structures.
- Uniformity. The entire minibus for the house is produced in many copies, and in case of marriage, the manufacturer can easily replace the desired part.
- The quality of the connection. Corner locks for construction are made in the factory using high-tech equipment. This guarantees the quality of the connection and the durability of the structure. It is especially important to cut precise grooves for a double or triple locking system.
Double beam technology
For the construction of walls from minibars, the technology of “double beam” is often used. It allows you to make a cavity in the walls, which is then filled with insulation materials. Then you can exploit wooden buildings even in the winter. In particularly cold regions, they often use not only the “double bar” technology, but also build houses “in three bars”. In this case, two cavities are provided for filling with insulation.
A single-bar system is used much less often. Basically they resort to it during the construction of spring-summer buildings: arbors, latrines, small summer houses.
It can be noted that the minibus does not require any final processing, except for various impregnation and protective fluids for woodthat is inherent in all materials from solid wood.
The erection of farm buildings in one minibus is simple, as some inaccuracies in corner locks and joints are allowed. If you have an idea to get a wooden house in a double or triple beam, it is best to entrust its construction to professionals.
