Abstract

The invention relates to a bearing wall reinforcing body and a method for reinforcing a bearing wall by using the same. The reinforcing body comprises a rigid mesh layer, and a fiber reinforced polymer layer (5) is arranged at one side of the rigid mesh layer. The method provided by the invention has the following advantages: the method is applicable to reinforcement on common brickwork bearing walls, organically combines the advantages of reinforcement of the fiber reinforced polymer FRP and reinforcement of a steel plate screen and reinforcement mesh, thus not only improving the whole property and collapse resistance capacity of brickwork walls, but also increasing the brickwork rigidity, improving the axial load bearing capacity and shearing-resistance bearing capacity of the brickwork, improving the anti-shock property of the brickwork, and being good in reinforcement effect; and the method not only is good in reinforcement effect and high in reliability, but also is simple to operate, convenient to construct, does not need special construction tools, needs small size increase of the brickwork, does not influence production, has high economic benefits and is especially applicable to large-scale maintenance and reinforcement on the bearing walls with brickwork structures.

Description

technical field [0001] The invention relates to the technical field of civil engineering structure reinforcement, in particular to a load-bearing wall reinforcement and a method for reinforcing the load-bearing wall by using the same. Background technique [0002] Masonry structure is a form of building structure with a long history in our country. At present, many buildings that continue to be used in our country still belong to masonry structure. However, the masonry structure has low compressive, tensile, and shear strengths, and poor seismic performance. Long-term use will cause many problems such as component cracking and insufficient bearing capacity. In addition, the addition of layers or changes in the use of masonry structures will result in insufficient bearing capacity of the original structure, and it is necessary to reinforce the load-bearing components to increase the bearing capacity of the structure. [0003] At present, the commonly used reinforcement metho...
