Anti-seismic reinforcing structure and method of old brickwork building

Abstract

The invention relates to a sheathed prefabricated anti-seismic reinforcing structure and a reinforcing method of an old brickwork building. Sheathed prefabricated structures are respectively arranged at two sides of the old brickwork building to anti-seismically reinforce the old brickwork building and the inner sides of the sheathed prefabricated structures are connected with the outer longitudinal wall of the old brickwork building; a roof straining beam is arranged on the roof and the sheathed prefabricated structures at the two sides are fixedly connected into a whole through the roof straining beam; the reinforcing structure consists of the sheathed prefabricated structures at the two sides and the roof straining beam; and the sheathed prefabricated structures respectively comprise a newly added longitudinal wallboard, a newly added transverse wallboard and a newly added floor. The anti-seismic reinforcing structure has reliable anti-seismic performance, and can ensure that the residents are unnecessary to move and the construction is carried out outdoor during the reinforcing construction; the constructional members are machined in a prefabrication way, therefore, the site construction time is short, the wet operation volume is small, the quantity of construction templates is less, and the work noise at the construction site is low; moreover, the anti-seismic reinforcing aim of the old building and the using condition improving aims are skillfully combined, thereby increasing the usable area and improving the life quality of the residents.

Description

technical field [0001] The invention relates to a building reinforcement structure and a reinforcement method, in particular to a prefabricated anti-seismic reinforcement structure and a reinforcement method of an existing masonry building jacket. Background technique [0002] With the improvement of social production and living standards, the anti-seismic fortification level of old buildings with a large number of large areas in the city has become a weak link in urban lifeline projects, and there are hidden dangers in anti-seismic safety, which require anti-seismic reinforcement. At present, Most of the existing old buildings are masonry structures. At present, there are not many seismic reinforcement measures for masonry structures, and they are all difficult. After the Tangshan earthquake in my country, some old buildings at that time were partially renovated. , using the method of adding ring-beam structural columns and steel tie rods to the old masonry building fo...

AI Technical Summary

Problems solved by technology

However, in the reinforcement project of brick-concrete structure, due to the narrow construction surface, the difficulty in connecting the brick wall and the newly added prefabricated wallboard, and the difficulty in hoisting and positioning of the prefabricated wallboard, there is no application at present.
