The time does not stand still, so new technologies come to replace new - light, practical and environmentally friendly. The wooden beam was always popular, but only in the XXI century came to the manufacture of a bodaur of wood, which made it possible to significantly finalize frame construction.

The main parameters of the product
With each new season, this material increases its popularity. It is usually used for frame construction, installation of floors, overlaps and partitions, as well as roofs. The specific type of Latin letter "I" with bars at the top and below allows the installation quite simple and quickly.
There are several advantages thanks to which the 2-way beam has gained its popularity: not bends, wear resistance, the lack of reaction to moisture (does not rot), the low mass and at the same time a relatively low price due to the reduced wood consumption.
If we consider the product in detail, you can see that it is not solid, but consists of several elements. OSP (oriented chipboard) or plywood is taken as the basis (oriented, the blocks from the bottom and above are made of glued timber, and all this is connected using a water-based wood glue. In the glued timber, there are special recesses of the desired width that allows you to immerse an OSP in them, thanks to which the design and acquires its highest reliability.
Drawing of the 2-way beam.
In factory conditions, 4 machines are used for such a process:
- Milling. On such a machine in a bar not only the longitudinal trench is made, but also grinding is performed, then not to hurt the skin during operation.
- Cutting OSP. It works parallel to the milling room to cut the desired number of plates to the deadlines with ideally accurate parameters. Sections are made at an angle of 45 °.
- Gluing. A thin layer of glue is applied to the bottom of the trench in the bars, after which the stove is inserted between 2 bars, and the entire design at the outlet is pressed.
- Press. Depending on the glue used, the machine holds the workpiece (0.5-2 minutes) under pressure, after which it rolls on to the final drying.

The work takes place at a very high speed, but not all are solved by all, since the price is obtained by 1.5-3 times lower.
Own study
Tools and materials:
- Bar;
- roulette;
- a circular saw;
- OSP;
- glue on wood;
- channel;
- clamps;
- sandpaper.
Here the whole process goes much slower, but the price drops significantly. Food beam with their own hands is manufactured in stages:
Food beams are made of timber, OSP and Schawler.
- Choose bars. The cross section depends on the preferences of the wizard, but not less than 35 * 25 mm. The larger the bar, the more reliably the design, but also a step by 2 of the 2 diothera during work will have to significantly increase.
- Here you should choose to use - electric saw, chainsaw or stationary circular. The advantage of chain saws is that they initially can do a trench of 10-12 mm, but they must be additionally fixed. In addition, their work is much more expensive than the circular. With a special desire, you can find cutters of the desired thickness and for circular saws (there are a little more expensive than normal), after which you can continue to work.
- The depth of groove is exhibited (10% of the total OSP length). With the total loss of 15 lengths, you can achieve perfect fixation.
- Brux cut. At the same stage, they need to be ground using grinding or sandpaper.
- The glue is applied to the bottom of the trench, after which the stove is immersed in it. Immediately, the same process is done with another 1 bar, and you can press the boutique.
- Not in every house there is a hydraulic press, so you can use a channel that is tightened with 2 belts and carbines (improvised clamps). Such a screed of a hem is no less effective than the press, though more troublesome.
Total for the manufacture of 1 diodeava takes up to 30 minutes. But if you do on the stream, the speed will increase several times. That is, first cuts it, for example, 100 beams that are grinding, then 50 plates are cut, after which it is all to be glued together. With such a work, the average production rate of 1 of the 2 can fall to 8-10 minutes. But in no case should not be hurry to prevent an error.
