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.

9. Referring to fig. 13, the a-die table 20 and the cage and the L-shaped mesh reinforcement attached to the second louver 2 are pressed into the first louver 1 on the B-die table 21 to a predetermined depth.

10. Referring to figure 14, the jig 25 is dismantled and the a-die table 20 is removed from the second blade 2.

11. Referring to fig. 15, concrete is poured into the integral mold of the opening side mold 24 and the combined mold 26 on the B-mold table 21.

12. Referring to fig. 16, after entering the cellar for secondary curing, the die on the die table 21B is removed, and a prefabricated member of the laminated wall with a plugging plate is formed.
