AI Technical Summary
During the hoisting process, the connection strength between the inner and outer leaf wall concrete and the insulation layer of existing precast insulated shear walls is poor, resulting in insufficient hanging force and impact resistance, and making them prone to cracking.
The structure adopts a combination of inner and outer steel mesh and insulation layer. Through the cooperation of the first and second connectors, the inner and outer steel mesh are connected by insert rods, wires and welding to ensure that the inner and outer steel mesh are tightly attached to the insulation layer. The stability of the wall during hoisting is ensured by dovetail blocks and dovetail grooves.
This improved the strength and impact resistance of the wall, ensured the hanging force, and prevented cracks between the inner and outer leaf wall concrete and the insulation layer, thus achieving the stability and rigidity of the precast insulated shear wall.
