Light steel keel ceiling anti support

Starting from the lower end of the boom, obliquely to the ceiling, install and connect a tie rod, the tie rod must have stiffness, and the boom forms a very stable triangle, what can be done with the counter support, the general use of angle iron or the diameter is more than 10mm of steel bar, there are also people will use the main keel, and the structure is reliably connected, the number and position should be calculated according to structural mechanics, and the site structure is determined.

When the length of the suspension bar is greater than the anti-support, the reverse support is in the case of the normal boom, from the lower end of the boom obliquely to the ceiling installation and connection of a tie rod, the tie rod should have a certain rigidity, and the boom to form a stable triangle to prevent the ceiling from deforming upwards when the air pressure changes, forming a dome, causing the destruction of the ceiling The number of counter-supports should be set according to the construction plan.

Counter support can be used for anything, generally using angle iron or steel bars with a diameter of more than 10mm, and there are also main keels used, but the following conditions must be met:

1. It has a certain stiffness;

2. It should meet the requirements of fire prevention and anti-corrosion;

3. Reliable connection with the structure;

4. The quantity and location should be determined according to the structural mechanics calculation and on-site structure.

In the layout of the reverse support installation, the reverse support should not be in the same straight line, it should be a plum blossom distribution, the support angle should be between 30 and 45 degrees, and the spacing should be about 2 meters, which can be adjusted according to the actual situation.

The lower end of the reverse support is usually fixed on the boom, but because of the material, it is not easy to rivet or think that the effect is not as good as directly riveting on the main keel, and many of them are directly anchored on the main keel in on-site construction.

According to the national norms, when the ceiling keel boom is greater than 1500mm, it is necessary to set up a reverse support. The specific method is: with angle iron or the main keel can be, one end is fixed on the floor slab, and the other end is fixed on the main keel of the ceiling.

The installation of counter-supports should not be in the same straight line, and should be distributed in a plum blossom shape, with a spacing of about 2M.

What role can counter-support do.

I don't understand what you are asking, I am a Dragon brand building materials dealer, if you don't understand anything, you can also call the dealer.

Yes? I've only heard about partition walls with anti-supports.。。

I haven't heard of any anti-support, but I have seen a lot of almost nothing, the same hanging, some 2 meters are almost the same hanging, is there a difference in the size of the same area.
