Old masonry anti-seismic reinforcement structure and construction method

Abstract

The invention discloses an old masonry anti-seismic reinforcement structure and a construction method. An old masonry building structure is subjected to anti-seismic reinforcing by arranging an outersleeve prefabricated member outside old masonry, a wall covering plate is connected to embedded steel bars embedded in the wall surface of the old masonry in a welded mode, an embedded part on the lower portion of a first layer wall covering plate is connected to an embedded part corresponding to a bearing platform in a welded mode, and shear wall plates are perpendicular to the wall surface of the old masonry and connected to the embedded steel bars embedded on the wall surface of the old masonry in a welded mode. The horizontal reinforcing bars reserved at both ends of a balcony plate are connected to the embedded parts at the upper end of the shear wall plates in a welded mode, the horizontal bars of the balcony plate are further connected to the embedded steel bars embedded in the wallsurface of the old masonry in a welded mode, the embedded part on the lower portion of the first layer shear wall plate are connected to the embedded part corresponding to the bearing platform in a welded mode, temporary supports are arranged between the shear wall plates, and external wall plates are separately connected and fixed to the outsides of the shear wall plates and the outsides of thebalcony plates. An original house surface is provided with additional ring beams which are fixedly connected with a sloping roof. The old masonry anti-seismic reinforcement structure improves the anti-seismic performance and energy-saving effect of an old house, increases the use area and improves the living comfort.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to an old masonry anti-seismic reinforcement structure and a construction method. Background technique [0002] With the rapid development of my country's economic environment, technical conditions, and great changes in social life, the houses built in the 1960s and 1980s have become old houses with high energy consumption and huge safety hazards. [0003] For old communities that do not meet earthquake resistance standards, have low construction standards, outdated facilities and equipment, and incomplete engineering facilities, it is necessary to carry out seismic reinforcement, leveling and slope modification, etc., to prolong the service life of old buildings. [0004] Most of the balconies in old communities are made of prefabricated concrete splicing. The panels of the old buildings have been in disrepair for a long time, with obvious signs of aging and cracking....

AI Technical Summary

Problems solved by technology

[0004] Most of the balconies in the old residential area are made of precast concrete splicing. The panels of the old buildings have been in disrepair for a long time, and the phenomenon of aging and cracking is obvious. After long-term erosion by wind and rain, steel bars are corroded, and the concrete of the fence is loose and falling off, there are certain safety hazards.
