[0002] With the increasing requirements for exterior wall waterproofing quality and the application of aluminum formwork technology, more and more high-rise and super-high-rise residential projects have adopted fully cast-in-place concrete exterior walls.

[0003] The fully cast-in-place concrete exterior wall includes two types of walls: one is the concrete shear wall exterior wall (hereinafter referred to as the shear wall) that serves as a structural load-bearing component, and the other is the concrete structural exterior wall (hereinafter referred to as the concrete structural wall) that replaces the original masonry exterior wall. In order to verify the structural design assumptions of the fully cast-in-place concrete exterior wall and ensure the seismic performance of the structure, it is necessary to separate the shear wall and the concrete structural wall from the perspective of load-bearing performance. Structural joints are the engineering technology to achieve this goal.

[0004] However, the existing structural joints are not firmly fixed during the construction process, and are easily displaced, twisted, and deformed under the impact force of concrete pouring and vibration, which affects the seismic performance of the structure. Utility Model Content
