Technical Field
[0001] The utility model relates to a shear wall external wall casting template, in particular to a shear wall external wall casting template reinforcement system with a polystyrene insulation board built in. Background Art

After the formwork reinforcement system is completed, on the upper side of the inner side of the insulation board Concrete is poured in turn on the upper ports of the ports, the double-layer mesh gaps and the surface layer gaps, thereby completing the pouring of the outer wall of the shear wall with the polystyrene insulation board built in. This traditional construction method has the following problems: (1) Since the inner support rods and the tension bolts pass through the holes in the insulation board, the insulation board will shift left and right along the inner support rods and the tension bolts during the positioning of the insulation board; (2) During the pouring and vibration of concrete, the pad set between the outer side surface of the double-layer steel mesh and the inner side surface of the corresponding wall formwork is prone to fall off, causing the double-layer steel mesh to abut against the outer formwork, resulting in the steel mesh being exposed on the outer side surface of the wall after the formwork is removed, requiring secondary repair; (3) Since the polystyrene insulation board is relatively soft, it is prone to tearing and damage during the pouring and vibration of concrete, resulting in damage to the insulation layer.
