Abstract

The invention discloses a method for reinforcing a building structure. The method is characterized in that a concrete floor slab reinforcement structure comprises sprayed concrete, carbon fiber cloth, steel bars, steel reinforcement split heads and a concrete floor slab, wherein a groove is formed in the lower part of the concrete floor slab; the groove is 50-60 mm in width and 20-25 mm in depth; the steel reinforcement split heads are arranged in the groove; the diameter of the steel reinforcement split heads is 8-10 mm; the space between the steel reinforcement split heads is 300-400 mm; the sprayed concrete is arranged at the lower part of the concrete floor slab; the sprayed concrete is 25-35 mm in thickness and C30 in strength; the carbon fiber cloth is pasted on the lower surface of the sprayed concrete; and the steel bars are pasted at the joint of a concrete column and the concrete floor slab for reinforcement. The method has the characteristics of safety, reliability, economy and reasonableness.

Description

technical field [0001] The invention relates to a building structure, in particular to a strengthening method for the building structure. Background technique [0002] With the development of the construction industry, more and more high-rise buildings appear, and construction engineering quality accidents also occur from time to time, which has to arouse the attention of the engineering field. Unreasonable behaviors in the process of design, construction, use, etc. may cause construction quality accidents and seriously threaten the personal and property safety of residents. However, for construction accidents with high cost, demolition and disposal will cause great economic losses. Therefore, a reasonable reinforcement treatment of the building can make the reinforced building not only save costs, but also meet the requirements of safe use, and achieve the goal of economical and reasonable. However, the traditional technology still cannot guarantee that the reinforced str...
