Construction method of double-shear wall template formwork at deformation joint

Abstract

The invention belongs to the technical field of construction of building deformation joints and particularly relates to a construction method of a double-shear wall template formwork at a deformation joint. Shear wall template support systems at two sides of the deformation joint are deeply researched and analyzed, a high-pressure hollow airbag is used as shear wall template supports at the two sides in the deformation joint, and the airbag can be inflated to form a pressure-proof rigid body to be combined with shear wall templates at the two sides and steel tube supports at the outer side of the deformation joint to form a steady two-side shear wall template support system, thereby realizing simultaneous support of the shear wall templates at the two sides of the deformation joint; and after the shear wall templates are dismantled, the high pressure airbag can be deflated to reduce the pressure so as to be smoothly removed, and then the templates at the inner side of the deformation joint can be conveniently lifted out sequentially, so that residual wastes of building construction do not exist in the deformation joint and the materials can be recycled many times.

Description

technical field [0001] The invention belongs to the technical field of building deformation joint construction, in particular to a construction method for supporting formwork of a double shear wall formwork at a deformation joint. Background technique [0002] According to the needs of structural design, buildings are usually equipped with deformation joints, and shear wall structures on both sides of the deformation joints are also very common in buildings. However, due to the small width of the deformation joints, the support and Demolition often has certain construction difficulties during structural construction. The traditional formwork construction method is to construct the shear wall on one side first, and then fill the deformation joints with fillers such as benzene plates when constructing the shear wall on the other side. It is not easy to control, and at the same time, the fillers such as benzene boards cannot be removed or the removal is not clean. Even if the ...
