Can the ceiling conversion layer screw be welded to the angle steel?

The ceiling conversion layer refers to the reverse support. According to the provisions of the "Code for Acceptance of Construction Quality of Building Decoration and Decoration Engineering", the distance between the boom and the end of the main keel is not more than 300mm, and when it is greater than 300mm, the boom should be added. When the length of the boom is larger, the counter-support should be set.

When the boom meets the equipment, the boom should be adjusted and added. It is also stipulated that it is applicable to the conversion layer structure that needs to be connected after more than 3 m.

The function of the reverse support is mainly to control the upward movement of the ceiling panel when negative wind pressure is generated in the room. When the plate surface is subjected to wind load, the plate surface will float up and down, and the boom is usually made of 6 10 steel bars, which can control the downward movement of the plate face, but cannot control the upward movement of the plate face. The reverse brace can support the plate surface and prevent the plate surface from moving upward, so as to control the deformation of the plate surface.
