Fast building earthquake-resisting reinforcing method and device

Abstract

The invention provides fast building earthquake-resisting reinforcing method and device. The fast building earthquake-resisting reinforcing device is a prefabricated part, the inner side of the prefabricated part is provided with a grout groove, and the grout groove is communicated with the outer side of the prefabricated part through more than one grout hole. The reinforcing method comprises the following steps of: removing the skin of the junction surface at the junction part between a wall of the reinforced building and the prefabricated part, and drilling anchoring holes in the wall, wherein the position of each anchoring hole is corresponding to the junction hole in the prefabricated part; installing the prefabricated part on the wall of the reinforced building through anchoring bolts, anchoring adjacent prefabricated parts, and fixedly bonding the prefabricated parts to the surface of the wall together. The technical scheme of field assembly of the prefabricated parts is adopted to reinforce the building, more than half field construction period can be shortened, the prefabricated parts can be produced in factories during school time, and enough time for ensuring production quality is guaranteed.

Description

Technical field [0001] The invention relates to a method and device for fast seismic strengthening of houses, in particular to a method for fast seismic strengthening of houses by using prefabricated external structural columns and ring beams, and a strengthening device including prefabricated structural columns and ring beams. Background technique [0002] There are still a large number of brick-concrete houses in civil buildings, and the brick-concrete houses are seriously damaged in the earthquake. Therefore, it is necessary to strengthen the existing brick-concrete houses without seismic design. The reinforcement mechanism is mainly to restrain the large deformation of the wall of the brick-concrete house, so that when the wall is severely cracked when it is hit by an earthquake, it will not immediately lose its bearing capacity and cause the collapse of the house, which will increase the energy consumption of the brick-concrete house. Capacity and improve ductility, so as to...

AI Technical Summary

Problems solved by technology

[0004] The construction of currently known cast-in-place additional structural columns and ring beams requires binding steel bars, setting formwork, pouring concrete, and removing formwork at the site of the reinforced house. People have a greater influence

Therefore, most areas of cities and towns currently strictly limit the impact of construction sites, control noise and environmental pollution, and generally do not allow the use of on-site mixing concrete

However, commercial concrete is not suitable for commercial concrete because the cross-sections of structural columns and ring beams are relatively small, and the amount of concrete required at one time is small, which will cause large waste.

Especially for primary and secondary schools, construction work cannot be carried out during the school term, and only two holidays in winter and summer can be used for construction, which takes about three months. Full reinforcement job in short order

[0005] In addition, the cross-sections of the structural columns and ring beams are relatively small, and the concrete is poured vertically. The construction work is difficult, and it is difficult to ensure the pouring quality of the structural columns and ring beams.
