Grid support

The grid support is an indispensable part of the grid structure. As the most basic load-bearing component of the grid, what types of grid supports are there? Today, the editor of Huahai Steel Structure will introduce to you!
The development of the grid structure has reached a relatively mature stage. Generally speaking, there are mainly the following types of grid supports:

1. For the grid support transformed from the basin-type bridge support, slightly adjust the structure of the upper support plate and the bottom basin of the bridge support to realize the tensile and resistance horizontal force of the grid support. The angle of this kind of grid is small, generally 0.02 radians, and the support contains rubber parts, so the service life should be clearly required.

2. The grid support transformed from the spherical bridge support. The corner of this type of grid support is relatively large, and the force surface is relatively uniform, without force necking. The upper and lower seat plates of the support are connected together by the principle of the chuck structure of the pressure cooker to realize the vertical tension resistance and horizontal resistance of the grid support. This kind of grid support is the mainstream product in the market.

3. Add leaf springs or polyurethane springs to the above-mentioned grid support to achieve special requirements such as the horizontal rigidity of the support.

4. The net support made by the principle of the spherical hinge, the realization of the rotation angle of this kind of net support is generally 0.08 radians, and the resistance to horizontal force is relatively large, but the friction coefficient of the spherical hinge surface is slightly larger, so attention should be paid.

5. In recent years, the joint bearing support has also been developed. The rotation of the time node of the joint bearing is placed in the support. The rotation of this support is flexible, but the displacement is limited.

This is the introduction to the types of grid brackets. For more knowledge of steel structure brackets, I look forward to the next introduction!
