Description
Technical field
Architectural engineering reinforcement technique field belonging to of the invention, more particularly to a kind of reinforcing for shear wall concrete replacement
Structure and its construction method.
Background technology
Also known as seismic structural wall, earthquake resistant wall, at present, reinforced concrete shear wall structure has been widely used in skyscraper shear wall, is
The important feature of horizontal loading and vertical load is primarily subjected in building.In architectural engineering, existing building is can be potentially encountered
The situation of shear wall Lack of support is, it is necessary to reinforce.Conventional reinforcement means has increasing section method for strengthening, affixing steel plate reinforcement
Method, displacement concrete strengthening method etc..Increasing section method for strengthening can reduce building free space；Although affixing steel plate reinforcement method is applied
Work speed is fast, but its steel plate pasted is poor with the cooperative ability of original wall body, influences consolidation effect；Displacement concrete strengthening
Although method can fundamentally solve the problems, such as former shear wall, common displacement method is higher and existing to temporary support requirement
Method cannot accomplish that shear wall displacement is constructed simultaneously with superstructure, while the Superstructure Construction duration is influenceed, construction peace
Full property is also relatively difficult to ensure card.In consideration of it, being solved the above problems the invention provides a kind of new method.
The content of the invention
For the technical scheme that the problem that prior art is present, the present invention are used for solution problems of the prior art
