Description

Technical Field

[0001] This utility model relates to the field of steel structure connection technology, and more specifically, to a connection component for building steel structures. Background Technology

[0002] Steel structure construction is a new type of building system that breaks down the boundaries between the real estate, construction, and metallurgical industries, integrating them into a new industrial system. This is why steel structure construction is widely favored by industry professionals. Compared to traditional concrete buildings, steel structure buildings use steel plates or profiles instead of reinforced concrete, resulting in higher strength and better earthquake resistance. Furthermore, because components can be factory-made and installed on-site, construction time is significantly reduced. The reusability of steel 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] Steel structure assembly and fixing points are mostly fixed with bolts. In large buildings, it is not convenient to frequently inspect and tighten the steel structure after it is fixed. After long-term use, the bolts may loosen, causing the building's stability and firmness to fail to meet the standards.

[0004] In view of this, we have studied and improved upon the existing problems to provide a connecting component for building steel structures. The aim of this technology is to solve the problems and improve its practical value. Utility Model Content
