The connection between the crossbeams 3 and the supporting steel structures 1 is welded, and the supporting steel structures 1 are equipped with a limiting mechanism 4 to prevent the crossbeams 3 from slipping. The ridge-shaped supporting steel structure 1 in this invention is formed by the right-angled sides of two right-angled supporting sub-frames 2. This modular design of the supporting steel structure 1 reduces the weight of individual modules, facilitating manufacturing and subsequent hoisting. Furthermore, in this invention, the connecting portion 203 of one of the supporting sub-frames 2 is provided with a connecting block 204 that inserts into the connecting portion 203 of the connecting sub-frame 2 it connects with. The connection between the connecting portions 203 after connection is fully welded, facilitating splicing and assembly.

[0017] The limiting mechanism 4 includes baffles 401 on both sides of the support beam 205 of the support subframe 2. The baffles 401 are provided with a disassembly mechanism to prevent the crossbeam 3 from sliding.

[0018] The disassembly mechanism includes a strip-shaped hole 403 on the baffle 401, which is parallel to the support sub-frame 2 in spatial direction. The partition block 402 has a through hole 404 corresponding to the position of the strip-shaped hole 403.

The partition block 402 can have a certain space for movement and adjustment, which facilitates the adjustment and alignment of the position. Then, the fastening bolt 405 is tightened, so that the meshing teeth 407 and the straight rack 406 mesh, which plays a role in loosening and preventing slippage.

[0019] The baffle 401 is welded to the support beam of the support subframe 2, and reinforcing ribs are provided between the two, which enhances the connection.
