Description

TECHNICAL FIELD

[0002] Fabricated building is assembled by prefabricated components on the construction site, that is, prefabricated components are manufactured in batches in a prefabrication factory, and the prefabricated components are assembled after being transported to the construction site, so that the fabricated building is assembled, the fabricated building is fast in construction, short in construction period, low in investment cost, controllable in quality, good in environmental protection and widely applied. Among them, the superimposed shear wall is one of the prefabricated components commonly used in the construction of fabricated building. Compared with the solid wall of the same size, the superimposed shear wall has the advantages of lighter self weight, lower transportation cost and higher hoisting convenience, and is widely applied.

[0003] The production and manufacturing process of the existing superimposed shear wall is as follows: the steel bars are bound at the construction site, then the steel bars are supported and molded, and finally the first wall body and the second wall body are poured and constructed in turn in the form of face interval pouring. As disclosed in the patent document CN109024989 A, a prefabricated shear wall body and a prefabricated shear wall body production method, the method specifically includes: setting a formwork around a mold table to form a pouring mold; placing the one side of the shaped steel reinforcement cage in the mold, pouring concrete into the mold to wrap the outer wall longitudinal reinforcement to form an outer wall panel; after the outer wall panel is formed, the shaped steel reinforcement cage is turned over by 180 degrees; the other side of the shaped steel reinforcement cage is placed in the mold, and the mold is poured into the concrete to wrap the inner wall longitudinal reinforcement to form an inner formwork. It can greatly reduce the amount of formwork, and improve the construction efficiency. However, in the construction process, the outer wall panel needs a long time from pouring to drying and forming, and the subsequent pouring of the inner formwork after turning over by 180 degrees also needs a corresponding drying and forming time, so that the construction period is long, the mold is more, and the construction cost is increased.
