Shanghai strong prestressed steel composite support

The prestressed steel composite support of Shanghai strong foundation adopts special fish-belly beam structure. This structure can reduce the use of steel components, significantly improve the construction conditions of underground space while ensuring the construction quality. Compared with the traditional support technology, the cost is reduced by more than 20%. The construction time of installation, demolition, excavation and underground structure is saved by 40%. The above.

Requirements for monitoring deformation of composite support of Shanghai strong section steel

Shanghai STRONG foundation STEEL composite support technology has the advantages of short construction period, low cost, large space and so on. It adopts prestressed fish belly beam structure, also called prestressed fish belly foundation pit steel support. At the same time, the construction quality is strictly controlled, the construction process is standardized, safety and quality first, and the deformation of foundation pit support is strictly monitored. The following is the deformation monitoring of a project:

Section steel combination support - Shanghai strong fish belly beam high strength bolt use precautions

Section steel combination support adopts high strength bolt link. In the construction process, there are the following precautions: 1. High strength bolt can not be used as a temporary bolt for installation. This is easy to cause the hole is not straight, or forced on the hole, so that the connecting plate fits, the screw thread damage of the bolt, the torque coefficient changes, the bolt shaft force is uneven, or the connecting plate produces internal stress.
