Tree logs are one of the most demanding alarm materials that can be stuck most often in an individualized life, for that it is important to consider the correct appearance between the logs of a private booth.

Logs - a chain of wooden beams, which are provided for mounting elements of black piedlogs (boards, sheets of plywood, chipboard, etc.). As a rule, for a log, choose a bar, trimming from coniferous species of a tree (pine, yalina, yalitsa, modrina).

As a rule, before installing the lag, it should be coated with antiseptic and anti-burn leaks.

Vologism of the tree at the time of stagnation of the lag is not to blame for the change of 18-20%. For the lag, a straight-sided bar is selected from spivvidnoshennyam sides, peretinu 1.5-2. The larger short side of the cross-bar of the bar is placed in the direction of the application of the static fastening.

If you do not have a beam of necessary overreturn, then it is allowed to store the storage lags from the boards, or a bar of less overretinu, nіzh rozrakhunkove. At the same time, there is an increase in efficiency - 1.2. In order to preserve the parity of the final stat, it is necessary to install the lags beforehand.

Lags for pidlogi virishuyut kilka zavdan:


VARIANTI VESTOVLENNYA LAG

Most often, there are three options for installing logs, which are provided for flooring.

Base for Chornovoy Pidlog

Lags can be used as a base for the installation of black piedlogs and mounted on the same wall.

In general, as a rule, the lags are fixed on the concrete slabs, or the main function is to reduce deformations and runnuvan chornovy and clean pidlog.

Stops lags

Lags can be installed on the support feet, mounted in the booth. At the same time, the lags are transmitted to the foundation on the target element. The management of the lags is vitrimati navantazhennya, which is available on the podlog on the podkritty and redevelopment on the support stovpi.

Lags - mіzhpoverkhove pekrittya


Lags can play a role not only as a basis for a pedagogue, but also as an element of an inter-upper crosshair and carry on them a static and dynamic changeover, override it on the other elements of a crosshair.

It seems that the most insignificant vimogues to the power of lag are presented in the first place. Tovshchina timber for lags is taken to the minimum overflow. At the same time, it is more common to focus on the heat-insulating ball, roztashovany mіzh lags, nіzh on rozrahunok mіtsnostі.

See the same between the lags to vibrate from the opening of the minimum sagging of the elements of the chornovoy pidlogi, whether it is a board or plywood. Recommended height 0.5-0.7 m

In the third option, the registration lag requires an accurate opening and distribution of lags. And in another option, it is necessary to re-grind the timber, since it is determined by the intermediate stop between the support stops.

It is possible to create the correct design of these parameters in a number of ways: behind the additional alarm tables, by storing special alarm programs, or by returning to the fakhivtsya-designer. I will try this kind of growth independently.

ROZRAKHUNOK PARAMETER LAG for pidlog

For the correct positioning, it is necessary to be reasonable, in terms of which characteristics, to lay down the technique of this design, and at the same time:

Otzhe, butt rozrahunku.

We vibrated a board for a chorny flooring with a standard thickness of 2.4 cm, the width of your room is 3 m. Dovzhin is 11 m. Two basic tables are used to vibrate the cross-bars of the timber and appear between the lags. For the width of the board 2.4 cm. The height between the lags is 40 cm. For the width of the spill is 3 meters and the size of the space is 300 kg / sq. M. it is recommended to use a bar with a pereriz 15 * 8cm.

Another special feature of the rocket is that it is necessary to be as minimal as the support wall and the extreme bar, in practice to become 3 cm. The number of lags is calculated according to the formula:

DP = RL * (SPD-1) + TL * SPD + KB * 2, de

  • DP- Dovzhina primischennya, for our butt - 11m = 1100cm.
  • RL- appear between lags (from the table) - 40 cm.
  • TL- the thickness of the lag (from the table) - 15 cm.
  • KB- from the extreme lag to the wall - 3 cm.
  • SPD- the number of lags - the number starts.

Putting the value into the formula, we will recognize:

1100 = 40 * (SPD-1) + 15 * SPD + 3 * 2

1100 = 55 * SPD-SPD-34

SPD = 1134/55 = 20.62 rounded up to 21 pieces

Now rozrakhumo vіdstan mіzh lags:

1100 = RL * (21-1) + 15 * 21 + 3 * 2

1100-6-315 = 20 * RL, RL = 38.95 cm.

If you use a crusty method, you can quickly shoot the rosters from the lags and from the lags to the private booth.
