FRP rib anchor rod anchoring head capable of applying prestress
The invention discloses an FRP rib anchor rod anchoring head capable of applying prestress. The FRP rib anchor rod anchoring head comprises a pull rod, a stretching nut, a steel sleeve, a locking nut, a positioning ring and a sealing ring, wherein threads are formed in the outer side of the positioning ring and connected with the threads in the inner side of the steel sleeve; a medium hole is used for fixing and positioning an anchor rod; a self-locking system is formed between the steel sleeve and the anchor rod according to the expansion feature of an expansion agent and is used for limiting the relative sliding of the steel sleeve and the anchor rod; meanwhile, the sealing ring can be embedded into an end gap between the anchor rod and the inner wall of the steel sleeve to be sealed. According to the FRP rib anchor rod anchoring head, the stretching anchoring manner is scientific and reasonable, simple and convenient; some devices can be recycled, and the strength can be ensured; the reliability requirement on application of prestress of the FRP anchor rod can be met; in addition, the sliding quantity of the steel sleeve and the anchor rod can be controlled after loading.
