1. Installation must be performed in strict accordance with process requirements. In general, first assemble the parts of the main components of the aluminum alloy truss, from the inside out or from the inside to the surface.

2. In the whole process of assembly and assembly of aluminum alloy trusses, it is not allowed to use compulsory methods to assemble components.

3. In order to avoid various internal behaviors and reduce the assembly deformation, appropriate hoisting machinery and assembly space should be provided in the pre-assembly site of the aluminum alloy truss.

4. The pre-assembly tire mold technology requires laying and its stiffness should be guaranteed. When pre-assembly of aluminum alloy truss members, they must be carried out in a natural state so that they can be correctly assembled at the installation position of related components.

5. All pre-assembled components must be finished steel components that have been qualified by the quality inspection department.

6. For the components that need to be made during pre-assembly, all components must pass the overall inspection after all the pre-assembly is completed, and the pre-assembly and binding can only be performed after confirmation.
