Anchoring structure of FRP rib cable and construction method of anchoring structure
The invention relates to an anchoring structure of an FRP rib cable and a construction method of the anchoring structure. The anchoring structure of the FRP rib cable comprises an anchor cup arranged on the protruding part of an FRP rib in a sleeving mode; a wire separating plate which is fixedly arranged in the anchor cup, wherein a plurality of holes are formed in the wire separating plate at intervals, and the FRP ribs correspondingly penetrate through the holes, so that set intervals are formed among the FRP ribs; an end plate which is used for blocking the through hole and is attached to the end part of the FRP rib; a first filler which is filled in the through hole; and an extension cylinder which is sleeved on the part, coated with the sheath, of the FRP rib cable and is fixed at the end part, far away from the end plate, of the anchor cup, wherein the extension cylinder is filled with a second filler. The problem that the anchoring difficulty of the large-tonnage FRP rib cable is large is effectively solved. The transverse extrusion of the anchoring filler on the FRP rib is reduced, and the wedge-shaped structure is additionally arranged at the end of the FRP rib, so that the anchoring efficiency and the overall anchoring strength of the rib cable are improved, the advantage of high strength of the FRP rib cable is fully played, and the overall reliability of a cable anchor system is improved.
本发明涉及一种FRP筋索的锚固结构及其施工方法，包括：套设于FRP筋的凸伸部分的锚杯；固设于锚杯内的分丝板，该分丝板间隔开设有若干孔洞，FRP筋对应穿设于孔洞，以使得若干FRP筋之间具有设定间距；供封堵于通孔且贴合于FRP筋的端部的端板；填充于通孔中的第一填料；以及套设于FRP筋索包覆有护套的部分且固定于锚杯远离端板的端部的延长筒，该延长筒内填充有第二填料。本发明有效地解决了大吨位FRP筋索锚固难度大的问题。通过减小锚固填料对FRP筋的横向挤压，在FRP筋端部增加楔形构造，以提升筋索的锚固效率和整体锚固强度，从而充分发挥FRP筋索高强度的优势，提升索锚体系的整体可靠性。
