Torsion and disengaging prevention clamping piece type anchorage device assembly part system
The invention discloses a torsion and disengaging prevention clamping piece type anchorage device assembly part system, and belongs to the technical field of prestress engineering. The torsion and disengaging prevention clamping piece type anchorage device assembly part system comprises clamping pieces, anchor plate taper holes and prestressed tendons. A clamping piece assembly body composed of the two clamping pieces used in the same anchor plate taper hole is a hollow variable cross-section body with the non-annular cross section. Each anchor plate taper hole is a variable cross-section body with the non-circular cross section. One clamping piece type anchorage device assembly part system body is composed of one anchor plate taper hole, the two clamping pieces used in the anchor plate taper hole and the corresponding clamped prestressed tendon. When the clamping piece type anchorage device assembly part system bodies are in a combined loading state of tension, compression, shearing, bending and torsion, the phenomena of clamping piece rotating and disengaging can be prevented by the binding effect between the clamping piece assembly bodies and the anchor plate taper holes. A prestress anchorage device in the above structural mode can effectively solve the problems of clamping piece rotating, disengaging and the like, which occur frequently to a clamping piece type anchorage device assembly part system, and the safety stock capacity of prestress structural engineering is improved.
