Reinforcement structure and reinforcement method for door and window openings of brick-concrete houses

Abstract

The invention relates to a reinforcing structure and a reinforcing method for a door and window opening of a brick-and-concrete house and belongs to the technical field of seismic reinforcement. According to the reinforcing method, after an original door and window is removed, a closed supporting steel frame playing a role in reinforcing the door and window opening is arranged on an original wall, the supporting steel frame consists of four groups of parallel steel channels, each group is formed by parallel and spaced arrangement of two steel channels, bottom plates of the two parallel steel channels in each group are connected through a batten plate, a base plate is arranged on each batten plate, and an anchor bolt sequentially penetrates through each base plate, each batten plate and the gap between the two parallel steel channels in each group to be anchored and connected with the original wall; every two adjacent groups of parallel steel channels are welded with each other, and steel angle lacing bars are welded at corners of the supporting steel frame. By the aid of the reinforcing structure and the reinforcing method, the load-bearing and shear-resistant capacity of the wall can be improved, extension of wall cracks during an earthquake can be effectively prevented, the seismic damage degree of the door and window opening can be reduced, and the safety performance of the brick-and-concrete house can be guaranteed.

Description

technical field [0001] The invention relates to a reinforcement and renovation measure, in particular to a reinforcement structure and a reinforcement method for door and window openings of brick-concrete houses, and belongs to the technical field of seismic reinforcement. Background technique [0002] Multi-storey brick-concrete structure houses are the main structural form in existing buildings in my country, accounting for more than 60% of civil buildings. However, the basic material and connection method of the brick-concrete structure determine its brittleness. Therefore, the brick-concrete structure generally has some characteristics such as small deformation capacity, poor seismic performance, low tensile, shear and bending strength, and large self-weight. Disadvantages, once a strong earthquake occurs, the earthquake damage is often more serious. Therefore, it is very necessary to carry out seismic reinforcement for brick-concrete structures that cannot meet the sei...
