Description

Technical Field

[0002] Prestressed carbon plate for bridges is a material used for strengthening bridge structures. It has the advantages of high strength, high rigidity, strong corrosion resistance, light weight, and convenient construction. Prestressed carbon plates can be used to manufacture bridge main beams and bridge decks, and can also be used for crack control reinforcement, plate beams, box beams, and T-beam bending reinforcement of reinforced concrete bridges. In bridge structures, prestressed carbon plates can effectively relieve the stress state of beams, give full play to their mechanical properties, and improve the bearing capacity and safety of bridges. Therefore, prestressed carbon plates have been widely used in the reinforcement of the bottom structure of highway bridges.

[0003] A tensioning tool for reinforced prestressed carbon plate construction disclosed in the Chinese utility model patent application disclosure CN214401337U has an ingenious and reasonable structural design. The prestressed carbon plate can be tensioned by placing a jack into the clamp groove of the tensioning baffle and extending the jack. Finally, the tightening nuts at both ends of the tensioning screw are tightened and the tensioning tool is removed to complete the tensioning. The operation is convenient, safe and reliable, and can be widely used in the tensioning construction of prestressed carbon plate reinforcement projects of buildings and bridge structures. It is worthy of promotion and application. However, the existing device structure is relatively simple, and it is impossible to limit the tensioning end anchor blocks of different sizes, and the overall practicality is low.
