Description

Technical Field

[0001] This utility model relates to the field of steel structure building technology, specifically to a prefabricated beam for steel structure buildings. Background Technology

[0002] Steel structure construction is a new type of building system. Compared with traditional concrete buildings, it uses steel plates or sections instead of reinforced concrete, resulting in higher strength and better earthquake resistance. Furthermore, because components can be manufactured in factories and installed on-site, construction time is significantly reduced. The reusability of steel also greatly reduces construction waste, making it more environmentally friendly. Therefore, it is widely adopted by countries around the world in both industrial and civil buildings.

[0003] Currently, precast steel beams are in use in existing steel structure buildings. Since the precast steel components often need to be connected together according to the building space, and the components are mostly fixed by welding, the operation is not only cumbersome and inflexible, but also inconvenient to disassemble after welding, which greatly affects the actual application effect of the precast beams. Utility Model Content

[0004] The purpose of this utility model is to provide a precast steel structure beam. By setting a connecting sleeve, a first fixing knob, and a first threaded groove, the first and second steel components can be connected end to end and quickly fastened together. Furthermore, by setting a baffle, a locking block, a second fixing knob, and a second threaded groove, a third steel component can be fastened to the connecting sleeve. This allows the third steel component to be vertically fixed between the first and second steel components. In this way, different combinations of steel component structures can be quickly achieved according to requirements. The operation is simple, convenient, flexible, stable, and easy to disassemble and maintain, resulting in good performance and overcoming the aforementioned shortcomings in the technology.
