Abstract

The invention discloses a basement roof crack repairing method and repairing structure. The basement roof crack repairing method comprises the following steps that the surface of the area, with a crack, of a basement roof is polished and roughened to form a polished and roughened area; a filling layer formed by smearing polymer cement mortar is smeared on the polished and roughened area and fills the crack; a tensile material is fixed to the filling layer and located between the two sides of the crack; and a filling layer is smeared on the filling layer and the tensile material to completely cover the filling layer and the tensile material, and the outer edge of the filling layer is flush with the surface of the basement roof. According to the basement roof crack repairing method and repairing structure, the filling layer firmly covers the polished and roughened area and fills the crack through the chemical binding force of the polymer cement mortar and the mechanical bite force formed by the polymer cement mortar and the polished and roughened area, so that the repairing effect on the crack is achieved, and then the tensile performance of the basement roof is further enhanced through cooperation of the tensile material and the filling layer.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a method for repairing a basement roof crack and a repair structure. Background technique [0002] At present, the cracking problem of large basement roof slabs occurs when the construction load is overloaded or the concrete strength is insufficient and it is put into use prematurely. Common repair methods for concrete slabs are grouting, steel plate pasting and reinforcement, etc. [0003] However, these methods are complicated to construct, and the steel plate is easily corroded by the environment, and the adhesive is also easily affected by the environment and temperature, and even leads to interface peeling, which cannot meet the repair requirements. Contents of the invention [0004] Based on this, the primary purpose of the present invention is to provide a method for repairing basement roof cracks that improves the quality of crack repair. [0005] Anothe...
