Method for constructing shear wall cast-in-place area by adopting decoration integrated plates

Abstract

The invention relates to a method for constructing a shear wall cast-in-place area by adopting decoration integrated plates. The method comprises the steps that a first prefabricated wall, a second prefabricated wall and a third prefabricated wall are installed; the decoration integrated plates are arranged on the outer wall surface of the first prefabricated wall and the outer wall surface of the second prefabricated wall; the first prefabricated wall and the second prefabricated wall are sequentially arranged in a spaced mode; the third prefabricated wall is perpendicular to the first prefabricated wall and the second prefabricated wall; the first prefabricated wall and the second prefabricated wall are arranged on the two sides of the third prefabricated wall correspondingly; the first prefabricated wall, the second prefabricated wall and the third prefabricated wall form the shear wall cast-in-place area in an enclosing mode; the decoration integrated plates stretch into the outer side of the edge of the first prefabricated wall and the outer side of the edge of the second prefabricated wall, so that an outer-side formwork of the shear wall cast-in-place area is formed; enclosing formworks and embedded parts are laid in other parts of the shear wall cast-in-place area; transversely-arranged U-steel is laid on the outer sides of the decoration integrated plates; soft cushion layers are arranged at the joints of the U-steel and the decoration integrated plates; the U-steel is connected with the third prefabricated wall through a bolt assembly; and concrete is poured in the shear wall cast-in-place area. According to the scheme, the prefabricated production links can be decreased, and the production efficiency is improved.

Description

technical field [0001] The invention relates to the field of construction, in particular to a method for constructing a cast-in-place area of ​​a shear wall by using a decorative integrated board. Background technique [0002] Traditional cast-in-place shear wall structure: post-insulation insulation on site, complex process, long construction period, high cost, and poor durability. The prefabricated shear wall structure in my country is still in its infancy. The cast-in-place area of ​​the prefabricated shear wall is mainly poured by PCF slabs. The PCF formwork in the cast-in-place area of ​​the edge components has the following technical problems: [0003] Compatibility: The insulation boards currently used are polymer materials, and organic materials are not compatible with concrete. The connection between the two is poor. At the same time, the expansion coefficient and other performance indicators are quite different, so it is not the best choice. [0004] Durability: T...

AI Technical Summary

Problems solved by technology

In actual production, it is easy to produce quality problems such as cracking

[0007] Higher cost: Due to the many links in the production method, the many insulation connectors, the surface layer of the outer leaf wall panel (50mm thick concrete slab), etc., the cost is higher than that of ordinary cast-in-place construction

[0008] In addition, inorganic boards are also used for anti-beating, but they cannot solve the problem of joints in the cast-in-place area
