The entire construction process of the steel structure space frame of the coal plant
The steel structure space frame of the closed coal plant should pay attention to the production quality of the high -strength bolt friction surface as much as possible and maintain maintenance before assembly to prevent pollution and rust. Before the assembly, please perform the anti -slip index value test of the high -strength bolt friction surface, check the high -strength bolts to confirm and produce batch numbers at the factory, and use the high -strength bolt to produce batch numbers on time. The high -strength bolt assembly requires that it can be worn casually and cannot be knocked and perforated; so it is necessary to prepare a certain amount of fetal shelf mold to adjust its deformation during the steel structure. This guarantees the stability of the specifications. The stacked contact area should be flat when the steel structure is assembled, the contact area should be as good as 75%as much as possible, and the edge gap cannot be higher than 0...
