Description

Technical Field

[0001] The utility model relates to the technical field of steel structures, in particular to an assembled steel structure of a public building which is easy to assemble. Background Art

[0002] Prefabricated steel structure, also known as prefabricated steel structure building, is a prefabricated building whose structural system is composed of steel components. It has no on-site cast-in-place nodes, is faster to install, has better seismic resistance, lighter weight, lower foundation cost, and steel structure is a recyclable material, which is more environmentally friendly. It is increasingly valued in large-scale construction fields such as public buildings and factories. There are at least the following disadvantages in the use of existing prefabricated steel structures: 1. When assembling, the existing prefabricated steel structure is usually made by drilling holes in the steel structure and then connecting them with bolts and nuts, but the holes will affect the overall structural strength of the steel structure and increase the time required for construction; 2. The existing prefabricated steel structure usually adopts bolt and nut connection or welding connection. The bolt and nut connection makes the assembly process of the steel structure more cumbersome and the disassembly more difficult. The welded steel structure is difficult to reuse after disassembly, which is not conducive to the recycling and renovation of materials and increases the cost of use. Therefore, we introduce a prefabricated steel structure for public buildings that is easy to assemble. Utility Model Content
