Embodiment Construction
[0037] Such as Figure 1-10 As shown, a prestressed fiber sheet combined assembly type tensioning device of the present invention includes a tension end anchor, a tension reaction frame, a tension guide rod 7, a tension baffle 12 and a jack 11;
[0038] The right end of the prestressed fiber sheet 1 is clamped in the tension end anchor, and two tension guide rods 7 are arranged in parallel along the left and right horizontal directions, the tension end anchor, the tension reaction frame and the tension baffle 12, From left to right, they are threaded on two tension guide rods 7 in turn. The two ends of the tension guide rods 7 are respectively threaded with a left lock nut 2 and a right lock nut 13. The right end of the left lock nut 2 is connected to the tension The left end surface of the end anchor is in contact with the left end of the right lock nut 13 and the left surface of the tension baffle 12; Surface top press fit;
[0039] An anchor connection structure is corres...

Abstract
A prestress fiber sheet combined and assembled tension device comprises a tension-side anchor, a tension reaction frame, a tension guide rod, a tension baffle and a jack; the tension-side anchor comprises a U-shaped plate, an upper anchoring plate and a lower anchoring plate, the right end of a prestress fiber sheet is clamped between the upper anchoring plate and the anchoring plate, the tension reaction frame comprises a connecting plate, a fixing plate and a bearing plate, and an anchor connecting structure is correspondingly arranged between the right side of the tension-side anchor and the left side of the tension reaction frame. The invention further discloses a construction method of the prestress fiber sheet combined and assembled tension device. Accordingly, the center of gravity of the tension guide rod and the center of gravity of the prestress fiber sheet are basically kept consistent, and the eccentric force problem in the prestress fiber sheet tension process is effectively solved. The tension reaction frame, the U-shaped plate and the tension-side anchor are connected in an assembled mode, installation is convenient and fast, after tension of the prestress fiber sheet is finished, the U-shaped plate can be removed, reutilization is achieved, and the engineering cost is lowered.
Description
technical field [0001] The invention belongs to the technical field of reinforcement and repair of civil engineering structures, and in particular relates to a prestressed fiber sheet assembled tensioning device and a construction method thereof. Background technique [0002] In recent years, fiber sheets (including carbon fibers, basalt fibers, etc.) have become a research and application hotspot in the field of civil engineering structure reinforcement and restoration due to their unique advantages of light weight, high strength, corrosion resistance, and convenient construction. The main disadvantage of the traditional paste fiber sheet reinforcement technology is that it cannot give full play to the high strength characteristics of the fiber sheet. A large number of studies have shown that pre-applying prestress before pasting the fiber sheet can effectively overcome this defect, that is, the strength utilization rate of the fiber sheet can be greatly improved after the ...
