A construction method using wall units for laminated shear walls

Abstract

The invention relates to a wall unit used for a laminated shear wall and a construction method using the wall unit. The wall unit comprises a steel wire frame, and an insulating layer and a casting layer filled on the steel wire frame, wherein the insulating layer is embedded into the steel wire frame; the casting layer is a prefabricated concrete protective layer arranged on one side of the insulating layer; mounting fixing holes are formed in the outer end face of the prefabricated concrete protective layer; auxiliary pulling fasteners are preburied inside the prefabricated concrete protective layer, and are mounted layer by layer during construction; vertical load-bearing bars are arranged on the inner side of an insulating board, and are connected with the auxiliary pulling fasteners in virtue of pulling fasteners used for anchoring; a casting template is arranged outside the vertical load-bearing bars, and then casting is performed on a cavity between the insulating layer and thetemplate, to form a cast-in-place concrete layer. The vertically adjacent wall units are fixedly connected through fixed parts and bolts, and then setting and casting operations of the template are carried out, the shear wall constructed by using the construction method can greatly simplify the construction process and also has the strength of an integral casting wall, and the requirement of the shear wall is highly met.

Description

technical field [0001] The invention relates to the field of building technology, in particular to a wall unit for a laminated shear wall and a construction method using the same. Background technique [0002] The shear wall uses reinforced concrete wall panels to replace the beams and columns in the frame structure, which can bear the internal forces caused by various loads and can effectively control the horizontal force of the structure. The shear wall structure is widely used in high-rise buildings. There are mainly two methods for the construction of existing shear walls. One is the formation of concrete poured on site. This method is greatly affected by the site environment during construction, and the construction complexity is relatively high. More manpower is required and the construction period is long. , in order to eliminate the influence of the above factors, another construction method has been developed in the prior art. The shear wall unit modules are manufac...

There are mainly two methods for the construction of existing shear walls. One is to form concrete on-site pouring. This method is greatly affected by the site environment during construction, and the construction complexity is relatively high. More manpower is required and the construction period is long. , in order to eliminate the influence of the above factors, another construction method has been developed in the prior art. The shear wall unit modules are manufactured in the factory, and then a plurality of shear wall unit modules are combined and fixed to form an overall shear wall structure , but with this construction method, there will be defects in the connection strength and matching accuracy between the shear wall unit modules. Therefore, the construction method for the shear wall needs to be improved
