The truss has the advantages of large space force, relatively light weight, large rigidity, and good seismic performance; it is generally used for dry coal shed truss, movie theater steel structure, exhibition hall, waiting hall, stadium stand awning, hangar, two-way large column truss structure Waiting for the roof of the truss project. It is popular with people for its high-efficiency stress performance, novel and beautiful form and quick and convenient truss construction. So how can we ensure the quality of the truss project? Based on past experience, the aluminum truss stage project believes that the following aspects should be done. Let's take a look.

1. When installing a truss project, the setting of temporary fulcrums should be taken seriously. The aluminum truss stage manufacturer suggests that the fulcrum and fulcrum elevation can be arranged before the truss is installed. The temporary fulcrum must not only make the force of the truss uniform during construction, but also pay attention to the stability of the temporary fulcrum foundation (scaffolding) to prevent the fulcrum from sinking.

2. The support for the temporary fulcrum of truss construction can be jack, which can be adjusted step by step during the installation process. Note that the adjustment of the temporary fulcrum should not be an adjustment of a certain point, but also consider the uniformity of the surrounding truss forces. Sometimes this local adjustment will deform and bend individual rods.

3. When disassembling temporary fulcrums, it should be noted that several groups of fulcrums should be lowered simultaneously. The aluminum truss stage manufacturers suggest that the decline should not be too large during the decline process. Support points should be gradually reduced in proportion, or be removed by a step-down method of no more than 100mm per step.

4. When installing and welding the welded ball truss, the deformation of welding shrinkage should be considered, especially for the overall hoisting truss project and the strip truss. After ground installation, the welding deformation and shrinkage value should be mastered before welding. When the steel truss is processed, the welding points (heating surface) are all on the upper side of the plane truss, so the structure is easily deformed due to unidirectional heating. The general deformation law is that after the truss is welded, the surrounding supports will gradually tilt freely. The aluminum truss stage manufacturer suggests that if the amount of deformation is large, the originally planned camber will be offset. If arching is not considered, welding will produce a large deflection value, which will affect the quality requirements for acceptance. Therefore, the construction of welded ball truss should consider the deformation factor of unidirectional heating.

Because the aluminum truss stage project plays an important role in the entire construction project, it is very important to strictly control the quality of the project. The project is not a trivial matter. Only by earnestly doing every part of the work can we ensure the smooth completion of the entire project.
