Oblique reinforcement reinforced concrete shear wall construction method based on equivalent rod piece model

Abstract

The invention relates to an equivalent rod piece model-based construction method of an inclined reinforcement reinforced concrete shear wall. The method comprises the following steps of: bouncing a wall body skin wire and a template control wire on a top plate; whether the positions of the steel bars are correct or not and whether the distance between the steel bars meets the requirement or not are checked according to the thickness of a wall outer skin wire and the thickness of a wall protection layer, and if displacement exists, the steel bars are adjusted in place; vertical steel bars in embedded columns on the left side and the right side of the wall column and door and window hole steel bar assemblies are bound; oblique reinforcing bars are bound in the solid wall and the perforated wall, and tie bars and cushion blocks are arranged; mounting a template; premixed concrete is adopted for pouring operation; performing maintenance; and dismounting the template. According to the invention, the arrangement structure of the crossed inclined reinforcements is adopted, so that steel is saved; the construction is more convenient than configuration of profile steel, and the construction period can be shortened; the plastic deformation is large, the earthquake energy is effectively dissipated, and better lateral displacement resistance and earthquake resistance are achieved.

Description

technical field [0001] The invention belongs to the technical field of civil engineering, and in particular relates to a construction method of an obliquely reinforced reinforced concrete shear wall based on an equivalent member model. Background technique [0002] The rationally designed reinforced concrete shear wall structure in my country has good integrity, large lateral stiffness, high bearing capacity, large elastic-plastic deformation capacity, and good seismic performance. However, the failure mode of the shear wall structure is inconsistent with the direction of the reinforcement method, and the performance of the steel bar cannot be fully exerted, which will lead to the waste of the steel bar. In view of the above defects, it is necessary to propose a diagonally reinforced reinforced concrete shear wall based on the equivalent member model. [0003] At present, in order to improve the tensile and shear performance of the reinforced concrete shear wall structure, ...
