Clamping piece type extrusion inhaul cable anchorage device of FRP rib material and anchoring method
The invention discloses a clamping piece type extrusion inhaul cable anchorage device of FRP rib material . The clamping piece type extrusion inhaul cable anchorage device comprises an extrusion anchor cup, a sleeve and the FRP rib, the extrusion anchor cup is a barrel, outer chamfers delta are arranged at the two ends of an outer cylinder of the extrusion anchor cup, the angle of the outer chamfers is smaller than the inclination angle gamma of a taper hole of an extrusion die, an inner chamfer alpha is arranged at one end of an inner cavity of the extrusion anchor cup, the sleeve is in wedge-shaped fit with an inner cavity of the extrusion anchor cup, the sleeve is a longitudinal slice cone, a central slice cone angle beta is larger than an inner chamfer angle alpha of the extrusion anchor cup, the angle difference between the central slice cone angle beta and the inner chamfer angle alpha is 0.1-0.5 degree, a plurality of circular through holes are formed in the center of the sleeve, and FRP ribs are inserted into the circular through holes in a penetrating mode. The size and shape of each part are controlled, and the surface of the FRP rib material is coated with the glue containing the fine sand, so that the friction force of the FRP rib material is increased, and the anchoring performance and the tensile property are improved.
本发明公开了一种FRP筋材的夹片式挤压拉索锚具，包括挤压锚杯，套管及FRP筋材，所述挤压锚杯为筒体，其外圆柱两端设有外倒角δ，该外倒角的角度小于挤压模的锥孔倾角γ，所述挤压锚杯内腔一端设有内倒角α，所述套管与挤压锚杯的内腔为楔形配合，该套管是纵向切片圆锥体，且中心切片锥角β大于挤压锚杯的内倒角α，两者的角度差为0.1～0.5°，所述套管中心设有多个圆形通孔，FRP筋材穿插在圆形通孔内。本发明通过控制各零件间的尺寸形状，并在FRP筋材的表面涂抹含细砂的胶水来增加其摩擦力，提高锚固性能和抗拉性能。
