Construction method of shear wall and column formwork for main structure

Abstract

The present invention relates to a construction method of beam slab first and then short limb shear wall and column formwork for the main structure. The method is constructed in sequence according to the following steps: a. Binding the short limb shear wall and column reinforcement; b. Installing the beam slab formwork; c. Binding beams and floor reinforcements: Before binding beams and reinforcements, the shear walls and column reinforcements must be corrected. Immediately after the beam reinforcements are bound, check and accept them, and then bind the floor reinforcements; d. Install the short-leg shear walls while binding the floor reinforcements , column formwork; e, pouring concrete: beams, floors, short-leg shear walls, and column concrete are poured at the same time. The invention enables the installation of the short-limb shear wall and column formwork and the binding of beams and floor steel bars that are not on the same working surface at the same time, so that the installation of the short-limb shear wall and column formwork changes from a key task to a non-critical work. It does not occupy the construction period, which shortens the construction duration of the main frame-shear structure main project, and greatly shortens the construction period of the main structure and the time interval for labor to stop working.

Description

technical field [0001] The invention belongs to the field of building construction, and in particular relates to a construction method of a beam slab first and then a short limb shear wall and a column formwork for a main structure. Background technique [0002] With the continuous development of urban construction, there are more and more small high-rise buildings and high-rise buildings. The short-leg shear wall column frame shear system is widely used in the design. According to the traditional construction method, the shear wall and column are poured first. The post-cast beam floor concrete construction method is difficult to control the quality of the concrete at the joints of walls, columns and beams, and the construction period is prolonged. [0003] Install the formwork according to the conventional method, and the construction sequence of the main structure of the short-limb shear wall and column is generally: binding the steel bars of the short-limb shear wall colu...
