Abstract

The invention provides a top-type prestressed reinforcement machine used in the field of building structure repair and reinforcement, which includes a housing, the right end of which is fixedly connected with a repair device, and four lifting blocks are evenly arranged at the lower end of the housing, so that The top of the housing is rotated with a rubberizing wheel, and the top of the housing is fixed with a feeding mechanism, and the feeding mechanism is connected with a tensioning wheel through carbon fiber cloth, and the tensioning wheel and the rubberizing wheel are in the same position. Horizontal plane, by setting the tension wheel to solve the problem proposed in the background technology when using carbon fiber cloth for reinforcement, if no prestress is applied to the reinforced carbon fiber cloth, only when the repaired component is subjected to secondary force and the structure is further deformed, the carbon fiber cloth can be used. Participating in the work, the strength utilization rate of the material is extremely low, the stiffness improvement is limited, and the improvement effect on the bearing capacity and deformation effect of the structural members is very limited.

Description

technical field [0001] The invention relates to the technical field of reinforcement and repair, in particular to a top-type prestressed reinforcement machine for reinforcement and repair of building structures. Background technique [0002] At present, one of the main technologies used in the construction industry for structural reinforcement is the reinforcement method of pasting steel plates or carbon fiber cloth. The method of pasting steel plates has defects such as long construction period, increased self-weight of structures, and high maintenance costs. In recent years, carbon fiber cloth has been used for repair and reinforcement. The construction method of pasting carbon fiber cloth is: first repair the surface of the repaired component, and polish it flat, then apply carbon fiber special glue, and paste the carbon fiber cloth directly on the repaired component. If no prestress is applied to the reinforced carbon fiber cloth during cloth reinforcement, the carbon fi...
