Flexible prefabricated shear wall-external window integrated construction system and its construction method

Abstract

The invention discloses a flexible prefabricated and assembled shear wall-external window integrated construction system. The flexible prefabricated and assembled shear wall-external window integrated construction system comprises a wall frame into which concrete is poured. A window hole is reserved in the wall frame. A window frame bench formwork is tightly attached to the inner wall face of the wall frame. A bottom window frame formwork, a window frame and a top window frame formwork are sequentially installed inside the window hole from interior to exterior. One face of the bottom window frame formwork is fixedly connected with the window frame bench formwork. The two sides of the window frame are fixedly provided with window frame embedded parts stretching into the wall frame. According to the flexible prefabricated and assembled shear wall-external window integrated construction system and method, the window frame formworks can be repeatedly utilized, the construction flow is easy and convenient, the time limit for a project is shortened, the higher stability is achieved after the window frame is installed, and the better waterproof and heat preservation effects are achieved.

Description

technical field [0001] The invention relates to a flexible prefabricated assembly shear wall-outer window integrated construction system and a construction method thereof, belonging to the field of building construction. Background technique [0002] At present, the common practice for the installation of external windows is as follows: reserve the opening of the external window during the main construction stage → improve the size of the base and the opening before installation → enter the external window → install the external window and fix it with expansion bolts → install the window frame and the wall The body gap is foamed and filled densely → the sealant is closed → the construction of external wall insulation and decoration. There are mainly following disadvantages: [0003] 1. The size of the reserved hole is difficult to control, and it is easy to be too large or too small. If it needs to be repaired, it will also cause a great risk of leakage in the later stage; ...

AI Technical Summary

Problems solved by technology

[0003] 1. The size of the reserved hole is difficult to control, and it is easy to be too large or too small. If it needs to be repaired, it will also cause a great risk of leakage in the later stage;

[0004] 2. From the main body to the decoration to the installation of doors and windows, multiple construction processes need to be interspersed, and there are certain difficulties in quality control;

[0005] 3. After the window frame is fixed, it is difficult to grasp the size of the gap between the window frame and the opening, too large or too small will greatly reduce the anti-seepage effect;

[0006] 4. The operation of the outer window frame seriously affects the subsequent work of the facade. If the construction period is delayed, it will affect the total construction period of the project
