Embodiment Construction
[0040] like Figure 1-7 As shown, a prestressed fiberboard tensioning end rectifying anchoring device of the present invention includes tensioning end anchorage 4, tensioning reaction force frame 9, tensioning guide rod 7, tensioning baffle 12 and jack 11;
[0041] The right end of the prestressed fiberboard 1 is clamped in the tensioning end anchor 4, and two tensioning guide rods 7 are provided in parallel along the left and right horizontal directions. The two tension guide rods 7 are threaded from left to right, and the two ends of the tension guide rod 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 with the tension rod The left end surface of the pulling end anchor 4 is in contact with the left end surface of the right locking nut 13 and the left surface of the tension baffle plate 12; The left side surface of 12 is press-fitted; between the tensioning end anchor 4 and the tensioning baffle pl...

A prestressed fiberboard tensioning end correction type anchoring device, comprising tensioning end anchorage, tensioning reaction frame, tensioning guide rod, tensioning baffle and jack; Equipped with a correction mechanism. The invention utilizes the linear relationship between the tension force and the elongation of the fiberboard to locate and install the tension reaction frame. When the inner tapping circular holes reserved on the bottom plate are basically coincident, high-strength bolts are used to connect the tension end anchorage with the tension reaction frame to complete the anchoring of the tension end anchorage. By applying the device and method of the present invention, the tension guide rod can be removed after the prestressed fiberboard tensioning is completed, which overcomes the common problem of insufficient durability of the existing prestressed fiberboard tensioning end tensioning guide rod anchoring method. The adopted rectifying mechanism can greatly reduce the cost and construction difficulty of actual reinforcement, improve the stress on the vertical plate of the tensioning reaction frame, and make the tensioning guide rod more reasonable in the tensioning process.
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 fiberboard tension end rectifying anchoring device and an anchoring method thereof. Background technique [0002] In recent years, the technology of reinforcing concrete structures with fiber materials has developed rapidly, and has been widely used in reinforcement projects with its unique advantages. The fiber sheet has high strength, but the elastic modulus is similar to that of steel, and its strength is exerted at the expense of deformation, so its high strength is difficult to fully exert. The research shows that this outstanding problem can be well solved by the reinforcement technology of prestressed fiber sheet. [0003] Existing prestressed fiber sheet anchors mainly include wave anchors, clip anchors, and flat anchors, but no matter what kind of anchors are used for reinforcement, jacks are req...
