Description

Superimposed wall prefabricated member

Technical Field

The present disclosure relates to building element construction, and more particularly, to a prefabricated member for a laminated wall.

Background

The assembly type building is developed rapidly, most of assembly structure systems are mainly solid prefabricated structures, but various problems are found in the practice process, for example, quality control is difficult due to the fact that on-site steel bars are connected; the self weight of the assembly member is large, so that the model of the tower crane is large, the field hoisting is difficult, and the transportation is inconvenient; the work load of the template and the steel bar caused by the connection of the post-cast strip is large, the manual demand is large, and the like. The laminated wall prefabricated member can also be called a laminated shear wall, and is a common prefabricated member in the assembly type building construction. The dead weight of the laminated wall is lighter than that of a solid wall of the same size. This also makes it possible to install the semifinished products on the site with cranes of lower bearing capacity. In addition, the superposed wall prefabricated member can be used as a template used during construction to replace the template support on two sides of the traditional cast-in-place wall body. Therefore, laminated wall prefabricated members are widely used.

However, the prefabricated member of the superposed wall at the present stage still adopts a construction mode of plugging the side wall of the cavity by a site erecting template and then pouring concrete in the cavity. The plugging of the cavity side wall refers to plugging of a peripheral opening of the cavity side wall on a plane where the thickness direction of the wall body is located. No matter the traditional bamboo wood template or the shaping aluminum template is adopted, a large amount of template supporting and disassembling workloads are needed on site. And when the laminated wall needs to be provided with the bay window, no ideal solution is provided at the present stage in view of the production mode of the flat die platform of the laminated wall, and a mode that the upper bay window plate, the lower bay window plate and the side plate are respectively prefabricated and then installed is generally adopted, so that the method has more abutted seams among components and is easy to leak water.
