Description

Technical Field

[0001] The invention relates to the technical field of building engineering, and in particular to a pre-embedded part wall connection node and a wall construction method. Background Art

[0002] During the wall construction process, it is necessary to set up scaffolding on the outer wall. In order to ensure the reliability of the connection between the scaffolding and the wall and avoid safety accidents such as the scaffolding toppling, the scaffolding is often connected to the wall by a pre-embedded wall connection structure. The existing pre-embedded wall connection structure often includes embedded parts made of steel bars or steel pipes. During the wall construction process, before pouring concrete, it is necessary to weld one end of the embedded part to the steel bar frame in the wall according to the design drawing to locate each embedded part and connect it to the steel bar frame. After the wall is poured with concrete, the other end of the embedded part extends out of the wall for connecting the scaffolding. However, after the scaffolding is removed, the exposed part of the embedded part is easily rusted and transmitted to the welding position with the steel bar frame, causing the steel bar frame to gradually rust. The rust of the steel bar frame will cause the bearing capacity and stability of the wall to be seriously reduced. Summary of the invention
