AI Technical Summary
At the connection between the large-span steel structure roof and the curtain wall, the existing rigid connection cannot coordinate deformation, resulting in node damage and unable to meet the normal use requirements of wind load, seismic load and temperature load.
The connection method of thick steel double-ear plates and pressure-bearing bolts is adopted. The steel columns are welded through thick steel single-ear plates to form a reliable connection relationship, which can adapt to the deformation caused by external loads. Combined with the fixation of steel pipes and limit nails, the stability of the main steel structure and steel columns is ensured.
It achieves a reliable connection between the steel columns and the main steel structure under external loads, avoids node damage caused by deformation, and ensures the safety and stability of the large-span curtain wall.
