Masonry wall body blast-resistant reinforcement structure

Abstract

The invention provides a masonry wall body blast-resistant reinforcement structure comprising a wall body, mortar, a steel wire mesh piece and a fixed frame. The steel wire mesh piece is laid on the fixed frame connected with the wall body through fasteners; pins are arranged between the steel wire mesh piece and the wall body; one ends of the pins are fixedly connected with the wall body, and the other ends of the pins are fixedly connected with the steel wire mesh piece; reinforcing bars are arranged on the outer side of the steel wire mesh piece; the two ends of the reinforcing bars penetrate through the steel wire mesh piece and are connected with the fixed frame; and the mortar is smeared on the steel wire mesh piece and the reinforcing bars. According to the masonry wall body blast-resistant reinforcement structure, the steel wire mesh piece is arranged, and the pins are connected with the wall body and the steel wire mesh piece, so that the wall body does not collapse under the action of a blasting load; and the reinforcing bars are arranged on the outer side of the steel wire mesh piece, and the two ends of the reinforcing bars penetrate through the steel wire mesh piece and are connected with the fixed frame, so that the strength of the steel wire mesh piece and the ability of a masonry wall to resist the lateral load are improved, cracking of the wall body is limited or delayed, the projection velocity of fragments breaking away from the wall body is decreased, the number of the fragments is reduced, and the blast-resistant ability of the wall body is improved.

Description

technical field [0001] The invention relates to the technical field of anti-explosion reinforcement of walls, in particular to an anti-explosion reinforcement structure of a masonry wall. Background technique [0002] Terrorist attacks and accidental explosions often pose serious threats to personal safety. Shockwaves from explosions can wreak havoc on brittle masonry infill walls. Masonry walls are prone to damage such as wall collapse and debris flying under the action of explosion impact loads. When the peak value of overpressure reaches a certain value, it will pose a threat to the safety of personnel. Casualties and damage effects due to debris cannot be ignored, in order to prevent or mitigate damage, we need blast-resistant reinforcement of masonry walls to prevent wall collapse and reduce the number of debris detached from the wall. [0003] At present, there are many kinds of wall reinforcement methods for masonry walls, such as outsourcing angle steel reinforceme...

AI Technical Summary

Problems solved by technology

[0006] The purpose of the present invention is to provide an anti-explosion reinforcement structure for a masonry wall to solve the problem of cracking and fragmentation of masonry walls in the existing anti-explosion reinforcement methods, and the projectile speed of the fragments is fast, the number is large, and the size is small. Reduce the deformation of the wall under the blast load, and improve the ability of the masonry wall to resist lateral load and blast
