Traditional extensive housing construction methods have been gradually replaced by industrialized and integrated construction methods. In this context, the laminated slab concrete shear wall structure came into being, which can realize the standardization and modularization of residential structural components, reduce the erection of on-site formwork supports, and also reduce the construction period.

However, according to the currently known information, including application publication number CN102912900A "a prefabricated assembly laminated slab concrete shear wall structure and its construction method" and authorized announcement number CN202925721U "a prefabricated assembly laminated slab concrete Shear wall structure", the wall ends of the current laminated slab concrete shear wall structure all use cast-in-place edge components. In actual implementation, construction workers need to bind steel bars on site and set up formwork, which reduces construction efficiency.

Contents of the invention

In view of the problems existing in the above-mentioned prior art, the present invention aims to provide a prefabricated concealed column laminated slab shear wall member with end sealing plates, which eliminates the need for laminated slab concrete without reducing the structural integrity. The steel bar binding and formwork erection of the concealed column at the wall end of the shear wall structure have achieved the technical effect of improving the construction efficiency of the composite slab concrete shear wall structure.

For realizing above-mentioned technical effect, the technical scheme that the present invention adopts is:

A prefabricated concealed column laminated slab shear wall member with end sealing plates, the member includes prefabricated interior and exterior wall panels, vertically distributed reinforcement bars, horizontally distributed reinforcement bars, triangular truss bars and concealed column ends, and the member also includes The concealed column longitudinal reinforcement and concealed column stirrup pre-buried in the prefabricated inner and outer wall panels arranged in the concealed column end, wherein, the concealed column stirrup includes several longitudinal parts and several In the horizontal part, the angle between the longitudinal part and the horizontal part is 90 degrees, and the longitudinal rib of the concealed column is fixedly connected with the angle.

It should be noted that an end sealing plate is also provided. The end sealing plate is composed of a flange plate and a web plate. Fixed connection.

In order to further optimize the present invention, several ribs are provided on the outer surface of the flange plate, and several ribs are provided on the inner surface of the web. Among them, the ribs on the surface of the flange plate make the flange plate have sufficient anchoring and anti-slip performance, and the ribs on the inner surface of the web make the web have sufficient out-of-plane stiffness, so that the end sealing plate has the strength to be used as a formwork and stiffness requirements.

As a preferred technical solution, the end sealing plate can be made of a material with low thermal conductivity, and the present invention proposes to use materials including but not limited to ABS plastic and PVC plastic with low thermal conductivity.

The beneficial effects of the present invention are:

1. Changed the traditional production method. Specifically, by improving the concealed column from fully cast-in-place to prefabricated and laminated, and setting an end sealing plate at one end of the concealed column that meets the strength and rigidity requirements for the formwork, the on-site workers’ reinforcement binding and formwork erection are eliminated ;

2. The end sealing plate is made of materials with low thermal conductivity, which avoids the generation of cold and heat bridges;

3. Reduce the labor force, improve the construction efficiency of the laminated slab concrete shear wall structure, and enhance the degree of industrialization of the building.
