Method and structure for enhancing brickwork structure and improving earthquake resistant performance of structure by using carbon fiber

Abstract

The invention relates to a method and a structure for enhancing a brickwork structure and improving earthquake resistant performance of the structure by using carbon fiber. The method comprises the following steps of: step one, determining a part to be enhanced and reconstructed and pre-treating the surfaces of a brickwork; step two, coating binder on the surfaces of the brickwork; step three, sticking carbon fiber cloth tapes on the surfaces of the brickwork in a gridding shape and in a double-surface symmetrical manner; step four, drilling a through hole; step five, using a carbon fiber pinto pass through the through hole, infusing glue in the through hole and sticking the carbon fiber pin with the brickwork; step six, dispersing the two ends of the carbon fiber pin which are exposed from the brickwork in a strip shape, and respectively sticking and fixing the two ends with the carbon fiber cloth tapes on the two surfaces of the brickwork in a petal shape; and step seven, additionally sticking a piece of glue-coated carbon fiber cloth in an each area in which strips are stuck. The method solves the technical problem that the carbon fiber cloth tapes on the two surfaces of the brickwork lack organic linkage and can not ensure the cooperative work of the carbon fiber cloth tapes and the brickwork structure. The adoption of the method can effectively enhance the whole earthquake resistant performance of the brickwork structure. Meanwhile, the method also has the advantages of simple and convenient construction, short construction period, no original space occupation, no load added to the structure or a foundation and low investment.

Description

technical field [0001] The invention relates to a method for strengthening a masonry structure and improving the anti-seismic performance of the masonry, belonging to the field of anti-seismic reinforcement and transformation of buildings. Background technique [0002] Masonry structure is widely used in the field of industrial and civil buildings in our country. However, due to the brittle nature of masonry materials, their tensile, shear, and flexural strengths are relatively low and their self-weight is relatively large; in addition, masonry structures appeared earlier, and many masonry structures were originally designed only The gravity load and wind load are taken into consideration but the earthquake load is not considered, the strength of the masonry is low, and structural measures such as ring-beam construction columns are lacking. Therefore, generally speaking, the seismic performance of masonry structure building walls is poor, and once a strong earthquake occurs...

Problems solved by technology

[0003] In order to solve the shortcomings of the traditional seismic strengthening method for strengthening masonry structure walls, such as long construction period, increased structure and foundation load, occupying building space, causing a large amount of displacement of existing pipeline equipment, and large investment, etc., in order to solve the problems of both sides of masonry Carbon fiber tape lacks organic connection and cannot guarantee the technical problem of carbon fiber cloth tape and masonry structure working together. This invention proposes a
