Description

Technical Field

[0001] The invention relates to the field of building construction, and in particular to a prefabricated wall installation hanging formwork and a construction method thereof. Background Art

[0002] The existing prefabricated wall construction process is to hoist the wall on the floor slab after pouring, and use gaskets under the wall to control the elevation (the floor slab is uneven). After the wall panel is placed, the gap (3-5cm) between the wall panel and the floor slab needs to be sealed with seat slurry (sealing warehouse process). There is also a method of separating each grouting port with seat slurry before the prefabricated wall is placed (separating warehouse process). After the above-mentioned sealing warehouse or dividing warehouse construction is completed, the grouting port is grouting construction. The existing seat slurry construction requires workers to bend down and squat for a long time, which consumes a lot of physical strength. At the same time, it is difficult to control the quality during operation. In the later stage of grouting, grouting material often leaks and cannot be filled. After grouting, the seat slurry needs to be removed, resulting in waste. Summary of the invention

[0005] The specific features of the present invention also include: The outer wall of the threaded barrel and the inner wall of the mounting sleeve are provided with threads that match each other.

[0006] Adjustable horizontal steel bars are arranged under the panel, and the adjustable horizontal steel bars are tied or welded to the reserved steel bars of the prefabricated wall.

[0007] The construction method includes the following steps: S1. During construction, first install the adjustable horizontal steel bars according to the predetermined position, then pass the prefabricated wall steel bars through the corresponding mounting holes and the threaded tubes on the panel, and place the hanging formwork mold plate on the adjustable horizontal steel bars; S2, passing the installation sleeve through the reserved wall steel bar and installing it on the threaded tube, finely adjusting the horizontality of the hanging formwork mold plate by using a bubble level, and tightening the limit bolts to fix the hanging formwork mold plate; S3. After pouring the slab concrete, remove the hanging formwork mold plate. The hanging formwork mold plate is placed on the floor slab surface to form a hanging formwork groove. Pour the pre-laid grouting material into the groove. After the prefabricated wall is installed at the designated position, the pre-laid grouting material is squeezed out from the bottom of the prefabricated wall to close the gap between the groove and the prefabricated wall, and then proceed to the next step of prefabricated wall construction.
