Among them, insulation decoration integrated panels have developed rapidly in recent years. Insulation panels are usually installed on the exterior wall base (exterior wall concrete base or waterproof mortar layer) through bonding and anchoring processes. The "General Specification for Waterproofing of Buildings and Municipal Engineering" GB55030 stipulates that the exterior wall of the frame filling or masonry structure with a waterproof grade of one should be provided with two or more waterproof layers. When two waterproof layers are used, a waterproof mortar and a waterproof coating or other waterproof materials should be provided. The anchor drilling operation of the insulation board will inevitably damage the waterproof layer on the bottom surface, especially the board seam waterproofing of the insulation decoration integrated panel is only through sealant, and rainwater entering from the board seam is prone to cause leakage hazards in the later stage of the exterior wall. Therefore, a waterproof and continuous exterior wall tension anchoring structure and process are needed to ensure the waterproof continuity of the exterior wall waterproof mortar layer and overcome the defects of the cumbersome installation process of the traditional insulation board in blocks and the difficulty in controlling the flatness.
