Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of light steel keel connection structure, and particularly relates to a modular light steel keel quick assembly structure. BACKGROUND

[0002] The modular light steel keel is a prefabricated component system formed by standardization production with light steel as raw material, and is widely used in the construction of building walls, suspended ceilings, floor slabs and other structures. Its core feature is "modularization", that is, by designing the keel component as a unit module with specific size and interface, the structure can be quickly built by combining and splicing the modules during construction. This type of keel has the advantages of light weight, high strength, good seismic performance, high construction efficiency, and the material can be recycled, which meets the needs of modern buildings for green environmental protection and industrialized construction. It has become an important structural component in the fields of prefabricated buildings, temporary buildings and interior decoration.

[0003] In the actual installation site of the modular light steel keel, the traditional connection technology often causes damage to the keel body. For example, in the construction of office building suspended ceiling, workers need to drill holes in the side wall of the keel with a hand drill to fix the intersection nodes of the main keel and the auxiliary keel, and then screw in the bolts. During this process, the drill bit often damages the galvanized anticorrosive layer on the surface of the light steel keel, exposing the internal metal substrate. If the construction environment is humid (such as the plum rain season in the south), water vapor will seep in through the holes, and red rust may appear at the drilling site within 3-6 months, and the rust area will gradually expand over time, not only weakening the structural strength of the keel, but also possibly causing local subsidence of the suspended ceiling, posing a safety hazard. In the installation of wall keel, the welding method is even more harmful. In the construction of light steel partition wall in a residential area, workers weld the vertical keel and horizontal rail together by electric arc welding. The high temperature will instantly change the metallographic structure of the steel around the welding point, forming a brittle zone. If the wall encounters a slight earthquake or surrounding construction vibration later, cracks are likely to appear in the brittle zone, causing the overall stability of the partition wall to decrease. In addition, the welding slag produced during the welding process will scratch the surface of the adjacent keel, accelerating the rusting process and seriously affecting the structural safety and service life of the modular light steel keel. SUMMARY

[0004] Therefore, the present application provides a modular light steel keel quick assembly structure to solve the above technical problems.

[0005] In order to achieve the above purpose, the present application adopts the following technical solutions:

[0019] Compared with the prior art, the modular light steel keel intelligent buckle connection system realizes non-destructive connection of the light steel keel through innovative mechanical occlusion structure design.

[0023] Based on the above, the present application provides a modular light steel keel intelligent buckle connection system which does not need to damage the original structure of the keel, has high connection strength, low construction requirements and convenient maintenance.
