AI Technical Summary
Traditional canopies rely on diagonal tie rods for cantilever construction, which leads to leakage and corrosion at anchor points, increased eccentric bending moments at nodes, weld cracking, and tie rod corrosion failure, reducing safety and lifespan.
The design incorporates connecting beams, cantilever beams, support beams, canopy installation beams, and waterproof canopy panels. These components are bolted together to form a triangular truss, distributing the load at the cantilever end. Exposed tie rods are eliminated, and integrated waterproofing is achieved by combining rubber waterproof pads and water-guiding structures.
It improves the ease of construction and connection strength of the tie-rod-free large cantilever canopy, enhances the overall safety and lifespan of use, avoids the risk of corrosion, and extends the life of the components.
