Description

Technical Field

[0001] The utility model relates to the field of bridge reinforcement equipment, in particular to a prestressed carbon plate intelligent tensioning device. Background Art

[0002] Prestressed carbon plates are a technology used to reinforce concrete structures of bridges. They are widely used in the reinforcement and repair of structures such as bridges, buildings and tunnels. When using prestressed carbon plates, tensioning equipment is required to install the prestressed carbon plates, and then the carbon fiber plates are adhered to the concrete surface using epoxy resin adhesives. For this purpose, an intelligent tensioning device for prestressed carbon plates is proposed.

[0003] When installing prestressed carbon plates, most of the existing tensioning equipment is troublesome in fixing the prestressed carbon plates on the tensioning equipment. If the fixation is not firm enough, the prestressed carbon plates may fall off during the subsequent tensioning. In addition, some tensioning equipment needs to fix the prestressed carbon plates for a period of time after installing the prestressed carbon plates. When fixing, most of the hydraulic rods are removed and then fixed with nuts. However, when the nuts are subjected to tension, the nuts may move slightly on the threads, which may cause them to lose the tensile strength of the prestressed carbon plates. For this reason, technical improvements are urgently needed. Utility Model Content
