AI Technical Summary
Existing steel truss corridor structures are prone to displacement under large wind loads, which may even lead to the risk of overturning, especially under uneven settlement and seismic action.
The system employs a sliding support and a limiting mechanism. The sliding support includes a bracket and a limiting mechanism. The limiting mechanism consists of a first limiting member and a second limiting member. The first limiting member is installed on the bracket, and the second limiting member is installed on the lower chord of the steel truss. Through the cooperation of the sliding groove and the limiting column, the steel truss is allowed to slide in the Y-axis direction, while the movement in the X-axis and Z-axis directions is restricted, thus ensuring the stability of the steel truss.
This effectively avoids the risk of steel truss offset and overturning in the X-axis direction, improves the safety and stability of the steel truss, and meets the stress release requirements of the structure under different loads and seismic actions.
