Description

Mounting support and mounting assembly are replaced to assembled opening type building bottom plate purlin

Technical Field

The invention relates to an assembly type opening building bottom plate purline replacing mounting support and mounting assembly, and belongs to the technical field of building engineering.

Background

Purlin structures are common load bearing building elements for existing buildings. Various steel beams, such as i-beams, rectangular tubes, etc., are commonly used. The structure can well bear the pressure of the building bottom plate when the span is small. However, when the span is increased, the conventional purlin structure cannot be provided with suspension members for connecting heavy equipment such as wind, water, electricity, packway and the like due to insufficient stress. For the technical problem, the existing solution method has a technical prejudice that the bearing capacity of the purline and the building bottom plate can be enhanced only by means of perforation welding and the like by adding a fixing piece. However, the above-mentioned treatment method usually performs destructive treatment on the building floor, which affects the service life of the building floor. The welding support component can bring certain safety risk to construction due to the fact that energy is consumed in the welding process and open fire exists. Meanwhile, when the contact area of the building bottom plate is small or the suspension points are too small, the stress of the suspension part is insufficient when the suspension load is increased in the conventional other known suspension parts.

In addition, the volume and the weight of the traditional purline structure are large, so that on one hand, the consumption of raw materials of the whole building is large, and the cost is high; on the other hand, the problems of low efficiency, long construction period and the like exist in the aspects of construction and installation, and meanwhile, large-scale hoisting equipment is required to be used.
