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 in the position of door and window entrance to a cave, the window frame still adopts traditional drilling nailing mode to fix, has great gap between the structure hole of window frame and coincide wall prefab, easily arouses house quality problems such as ventilative hourglass water.

a closure plate disposed at the open end; the plugging plate comprises a plugging connecting piece and a plugging main body; the plugging connecting piece connects the plugging main body with the first blade and/or the second blade; the closure body is for closing off the cavity at the open end.

2. A laminated wall preform according to claim 1 wherein the connector assembly comprises a first rebar assembly disposed within the first leaf, a second rebar assembly disposed within the second leaf, and a connector rebar assembly; the connecting steel bar assembly is respectively connected with the first steel bar assembly and the second steel bar assembly.

3. A laminated wall preform according to claim 2 wherein the blocking connector extends into the first leaf at one end to connect to the first rebar assembly and extends towards the second leaf at the other end.

4. A laminated wall preform as in claim 1 wherein the closure panel further comprises an anchor; one end of the anchoring piece is connected with the plugging connecting piece, and the other end of the anchoring piece extends into the cavity.

5. A laminated wall preform according to claim 1 wherein said open end is further provided with a stop member disposed in said cavity between said first section and said second section for stopping concrete pouring said closure panel from entering said cavity.
