Description

Technical Field

[0001] The utility model relates to the technical field of steel roof trusses, and more specifically, to a shock-absorbing steel roof truss. Background Technique

[0002] With the acceleration of the urbanization process and the frequent occurrence of natural disasters, the seismic performance of buildings has become an important consideration in architectural design. As one of the main structural forms of modern buildings, steel structures are widely used because of their high strength, light weight, fast construction speed, etc. There are many types of steel roof trusses on the market, and most of them have the advantage of stable support.

[0003] However, when the steel roof trusses on the market are in use, they mainly resist seismic forces through the rigidity and strength of the structure. Although the rigidity and strength can meet the requirements and achieve a certain seismic effect, these types of steel roof trusses are all rigid structures, and the connecting parts and supporting parts of the rigid structures lack corresponding shock-absorbing components, which is not conducive to shock-absorbing operations and easily causes cracks and other situations in the rigid-structured steel roof trusses after being shaken, affecting the stability of their structures. In view of this, we have proposed a shock-absorbing steel roof truss. Summary of the Utility Model
