AI Technical Summary
The color steel plate ceiling structure of the static pressure box layer of the clean room in the steel structure factory has problems such as heavy weight, many consumables, and affecting air tightness and stability. It is especially difficult to ensure cleanliness when applying fire retardant paint.
A combination structure of multiple first C-shaped steels and second C-shaped steels is adopted. The color steel plate is set on the top of the first C-shaped steel. It is connected to the T-shaped keel ceiling through U-shaped clamps and hangers, which reduces the use of profiles. Porous C-shaped steel is used instead of double-pieced C-shaped steel to improve stability and airtightness.

Figure 2 The conventional method is to use a U-shaped clamp to connect the original grape trellis C-shaped steel and double-spliced C-shaped steel, and then hang the color steel plate and the T-shaped keel to complete the static pressure box suspended ceiling. However, this method uses double-spliced C-shaped steel, which is heavy, and consumes a large amount of material due to a large site, which may have an impact on the structural load, overall cost and the like of the entire steel structure factory building; secondly, this method has a certain impact on the air tightness of the static pressure box layer, the hanger rod of the color steel plate passes through the middle of the color steel plate, and the electromechanical pipelines in the static pressure box also pass through the middle of the color steel plate, which affects the air tightness and may also be affected by pipeline resonance caused by equipment operation, thereby affecting the stability of the entire suspended ceiling.
