A device for preventing the collapse of a masonry structure building caused by an out-of-plane instability of the wall

Abstract

The invention discloses a device for preventing wall out-of-plane unstability from causing collapse of a building of a masonry structure in an earthquake. The device comprises a steel wire gauze, vertical steel pipes, horizontal steel pipes, anchoring steel bars and structural adhesives, wherein the vertical steel pipes and the horizontal steel pipes are tightly attached to the wall surface of the building of the masonry structure; the vertical steel pipes are connected with a building panel, a floor panel and a foundation beam of the building of the masonry structure through the anchoring steel bars; the horizontal steel pipes are connected with the vertical steel pipes in a welding mode. The vertical steel pipes and the horizontal steel pipes form a rectangular area in a defined mode. In the rectangular area, the steel wire gauze is laid with the vertical steel pipes and the horizontal steel pipes as the edges, the steel wire gauze, the vertical steel pipes and the horizontal steel pipes are connected through welding seams, and the steel wire gauze and the wall surface of the building of the masonry structure are bound through the structural adhesives. The device can be arranged on one face of the building wall of the masonry structure, and can also be arranged on two faces. By the adoption of the device, when the building of the masonry structure is in an earthquake, the out-of-plane deformation of the wall body is limited by the device, and the wall out-of-plane unstability can be prevented from causing collapse of the building of the masonry structure in the earthquake.

Description

technical field [0001] The invention relates to a wall reinforcement device for a masonry structure house, in particular to a device for preventing the collapse of a masonry structure house caused by an external instability of the wall, and is a device for preventing the collapse of an existing masonry structure house The device belongs to the field of earthquake prevention and disaster reduction in construction engineering. Background technique [0002] Masonry structure houses have been widely used in industrial and civil buildings. Because of their low cost and relatively low technical requirements, they exist in large numbers in cities and rural areas of our country. The Ministry of Construction of my country has issued relevant specifications to guide the design and construction of masonry structures. The latest specification version is: "Code for Design of Masonry Structures" (GB50003-2011). The previous earthquake damages in recent years have shown that masonry struc...

Problems solved by technology

[0014] Third, the distance between the newly added ring beams and structural columns is relatively large. If the quality of the mortar used in the masonry structure is not high-this problem is common in many rural dwellings and old historical buildings-this method is very useful for raising the wall Poorly effective outside security
