Abstract

The invention provides a top type prestress reinforcing machine used in the field of building structure repairing and reinforcing. The top type prestress reinforcing machine comprises a shell, wherein a repairing device is fixedly connected to the right end of the shell, four lifting blocks are uniformly distributed at the lower end of the shell, a gluing wheel is rotatably arranged at the top end of the shell, a feeding mechanism is fixedly arranged at the top end of the shell, the feeding mechanism is connected with a tensioning wheel through the carbon fiber cloth, and the tensioning wheel and the gluing wheel are located on the same horizontal plane. By arranging the tensioning wheel, the problems that in the background technology, if prestress is not applied to the carbon fiber cloth for reinforcement when the carbon fiber cloth is adopted for reinforcement, only when a repaired component is subjected to secondary stress, and when the structure further deforms, the carbon fiber cloth can participate in work, the material strength utilization rate is extremely low, rigidity improvement is limited, and the improvement effect on the bearing capacity and the deformation effect of the structural component is very limited are solved.

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...
