The invention discloses a prestress fiberboard tension end anchoring device and method. The anchoring device comprises a tension end anchor, a tension reaction frame, a tension guide rod, a tension baffle and a jack. By means of the linear relationship between fiberboard tension force and elongation, the tension reaction frame is positioned and installed, when a fiberboard is tensioned till a kidney-shaped hole reserved in a tension end anchor cover plate basically coincides with an internal tapping round hole reserved in a bottom plate of the tension reaction frame, the tension end anchor and the tension reaction frame are connected through high-strength bolts, and anchoring of the tension end anchor is completed. By means of the device and method, the tension rod guide can be detached after fiberboard prestress tensioning is completed, and the common problem that durability is poor in an existing prestress fiberboard tension end tension guide rod anchoring method is solved.
Description
technical field [0001] The invention belongs to the technical field of reinforcement and repair of civil engineering structures, and in particular relates to an anchoring device and an anchoring method for a tension end of a prestressed fiberboard. Background technique [0002] In recent years, fiberboard (including carbon fiber, basalt fiber, etc.) has become a research and application hotspot in the field of civil engineering structure reinforcement and repair due to its unique advantages of light weight, high strength, corrosion resistance, and convenient construction. The main disadvantage of the traditional paste fiberboard reinforcement technology is that the high strength characteristics of the fiberboard cannot be brought into play. A large number of studies have shown that pre-applying prestress before pasting fiberboard can effectively overcome this defect, that is, the utilization rate of fiberboard strength can be greatly improved after prestressing is applied to...
