Method and structure for reinforcing shear wall by embedding high-strength self-stressed concrete truss

Abstract

The invention discloses a method and structure for reinforcing a shear wall by embedding a high-strength self-stressed concrete truss. The vertical bearing capacity and horizontal bearing capacity ofthe original shear wall are calculated by determining the boundary range of an unqualified area of the concrete strength in the original shear wall, the strength of concrete in the unqualified area and the strength of concrete in a qualified area, according to calculation and analysis results, a structural form of the embedded high-strength self-stressed concrete truss, an embedding position, thesize of the high-strength self-stressed concrete truss and the strength grade of high-strength concrete are determined, the part of the original shear wall to be embedded with the high-strength self-stressed concrete truss is chiseled away, through the treatment of a joint surface, formwork erecting after implanting of joint bars and pouring of the high-strength self-stressed concrete, the embedded high-strength self-stressed concrete truss is formed, and a reinforced shear wall meets the requirements of structural rigidity and bearing capacity. According to the method and structure for reinforcing the shear wall by embedding the high-strength self-stressed concrete truss, the wall thickness is not increased, the concrete excavation amount is small, and a remaining wall body can provide abearing capacity for reinforcement construction and later use.

Description

Technical field [0001] The invention relates to the field of building structural engineering reinforcement, in particular to a method and structure for embedding a high-strength self-stressing concrete truss to strengthen a shear wall. Background technique [0002] A concrete shear wall is a wall in a house structure that mainly bears horizontal loads and vertical loads caused by wind loads or seismic loads. The shear wall is an important load-bearing component in the house structure, and its load-bearing capacity is of great significance to the safety of the house structure, so it is very important to ensure the load-bearing capacity of the shear wall. [0003] During the concrete pouring process of concrete shear wall, due to improper control or other reasons, the beam and slab concrete is poured into the shear wall from time to time, or due to insufficient concrete material grade, some or all of the concrete shear wall is caused The strength cannot meet the design requirements....
