Vertical unbonded prestressed anti-seismic reinforcing structure for masonry building

Abstract

The invention discloses a vertical unbonded prestressed anti-seismic reinforcing structure for a masonry building. The structure comprises a wall body, wherein a plurality of layers of floor slabs are arranged on the wall body, a roof panel is arranged at the top end of the wall body, a plurality of evenly distributed hollow reinforcing plates are arranged at the top end of the roof panel, and symmetrically arranged fixing blocks are arranged at the top ends of the hollow reinforcing plates. The structure has the beneficial effects that the anti-seismic reinforcing rib is arranged in the vertical mounting groove, and a reinforcing rib, a reinforcing convex strip, an inner steel bar connecting sleeve, an arc-shaped strip, a hollow filling layer and an outer steel bar connecting sleeve are arranged in the anti-seismic reinforcing rib, so that the strength of the center part of the anti-seismic reinforcing rib is improved, and meanwhile, the elasticity of the exterior of the anti-seismic reinforcing rib is also improved; when an earthquake happens, as the exterior of the anti-seismic reinforcing rib is made of the elastic steel material, slight deviation can be generated, and meanwhile, the reinforcing rib is arranged in the anti-seismic reinforcing rib, a phenomenon that the anti-seismic reinforcing rib inclines excessively can be avoided, and anti-seismic reinforcing protection is effectively conducted on a wall.

Description

technical field [0001] The invention relates to the technical field of building anti-seismic reinforcement, in particular to a vertical unbonded prestressed anti-seismic reinforcement structure of a masonry building. Background technique [0002] Due to the backward technology and low construction cost of many early old houses in China, their seismic strength is insufficient. In order to make the seismic strength of the early old houses meet the local earthquake resistance standards, the earthquake resistance appraisal of the early old houses is carried out. And building seismic toughness evaluation, strengthen the early old buildings through building seismic reinforcement technology, and then pass the building seismic construction acceptance, and acceptance includes five major steps: foundation trench acceptance, underground part acceptance, main body acceptance, completion acceptance and seismic strengthening acceptance , so as to ensure the seismic strength and safety o...

AI Technical Summary

Problems solved by technology

[0003]The existing anti-seismic reinforcement methods for old houses have relatively complicated procedures, long construction period and difficult quality control. At the same time, the existing anti-seismic reinforcement methods are highly destructive. It affects the appearance and internal components of the house, which can easily lead to the collapse of the house. Due to the strong destructiveness and the exposed installation of the anti-seismic fixing mechanism, the concealment of the anti-seismic fixing mechanism is reduced, which greatly affects the aesthetics of the remodeled house and does not meet the needs of users. need
