Embodiment Construction
[0046] like Figure 1-Figure 11 As shown in the figure, a combined rectification type prestressed fiber sheet tensioning device of the present invention includes a tensioning end anchor, a tensioning reaction force frame, a tensioning guide rod 7, a tensioning baffle 12 and a jack 11;
[0047] The right end of the prestressed fiber sheet 1 is clamped in the tensioning end anchorage, and two tensioning guide rods 7 are arranged in parallel along the left and right horizontal directions, the tensioning end anchorage, the tensioning reaction force frame and the tensioning baffle 12, The two tensioning guide rods 7 are sequentially threaded from left to right. The two ends of the tensioning guide rods 7 are respectively screwed with a left locking nut 2 and a right locking nut 13. The right end of the left locking nut 2 is connected to the tensioning guide The left end surface of the end anchor is in contact with the left end surface of the right locking nut 13 and the left surfac...

Assemble and assemble the rectification type prestressed fiber sheet tensioning device, including tensioning end anchorage, tensioning reaction frame, tensioning guide rod, tensioning baffle and jack; tensioning end anchorage includes U-shaped plate, upper anchorage Plate and lower anchor plate, the right end of the prestressed fiber sheet is clamped between the upper anchor plate and the lower anchor plate. An anchoring connection structure is correspondingly arranged between the left sides of the tension-reaction frame. The invention also discloses a construction method for combining and assembling a deviation correction type prestressed fiber sheet tensioning device. The invention keeps the center of gravity of the tension guide rod basically the same as the center of gravity of the prestressed fiber sheet, and solves the problem of eccentric force in the tension process of the prestressed fiber sheet. The tension reaction frame, U-shaped plate and tension end anchorage are assembled and connected, which is convenient for installation, can be reused, and reduces the engineering cost; The tension guide rod is more reasonable.
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 combined assembly rectification type prestressed fiber sheet tensioning device and a construction method thereof. Background technique [0002] In recent years, fiber sheet (including carbon fiber, basalt fiber, etc.) has become a research and application hotspot in the field of civil engineering structural reinforcement and repair due to its unique advantages of light weight, high strength, corrosion resistance, and convenient construction. The main disadvantage of the traditional bonding fiber sheet reinforcement technology is that the high strength properties of the fiber sheet cannot be exerted. A large number of studies have shown that pre-stressing the fiber sheet can effectively overcome this defect, that is, the pre-stressing of the fiber sheet can greatly improve the strength utilization rate of the fiber she...
