AI Technical Summary
In the existing technology, the method of fixing the triangular bracket to the side wall by the pre-embedded bolts of the inclined anchor cannot effectively resist the lateral pressure of the side wall concrete, which causes the steel formwork panel to float, displace and deform, resulting in quality defects such as formwork bulging, grout leakage, root rot and misalignment of the concrete side wall.
A side wall formwork reinforcement system is adopted, which uses a horizontal tension structure to fix the triangular support device to the pre-cast low wall, and an anti-buoyancy structure to fix the triangular support device to the ground below, ensuring the stability of horizontal and longitudinal tension and resisting the lateral pressure and buoyancy during the concrete pouring process.
It effectively prevents the steel formwork panels from floating and shifting, avoiding quality defects such as bulging, grout leakage, root rot, and misalignment of concrete side walls, thus improving construction quality and efficiency.
