FRP rib clamping piece type anchorage device and anchoring method
The invention discloses an FRP rib clamping piece type anchorage device and an anchoring method. The anchorage device comprises an anchor cup (2), a split clamping piece (3), a fastener (4) and a gasket (5). A first through groove (201) of which one end is large in diameter and the other end is small in diameter is formed in the anchor cup, and the first through groove coaxially penetrates through the anchor cup in the axial direction of the anchor cup; the outer surface of the split type clamping piece is of a conical structure with the diameter of one end large and the diameter of the other end small, and the split type clamping piece is coaxially embedded in the first through groove of the anchor cup. Second through grooves (301) with the same diameter are formed in the split type clamping pieces, so that the FRP ribs coaxially penetrate through the anchor cup and the split type clamping pieces through the second through grooves; the fastening piece is clamped on the free end of the FRP rib, and the fastening piece is pressed on the large head end of the split clamping piece through the gasket. The problems that in the prior art, an FRP rib is prone to fatigue damage at a notch, and a clamping piece cannot follow up in time, so that the anchoring effect is poor, and bonding operation is inconvenient can be solved.
本发明公开了一种FRP筋夹片式锚具及锚固方法，该锚具包括锚杯(2)、分片式夹片(3)、紧固件(4)和垫片(5)；锚杯内部形成有一端直径大、另一直径端小的第一通槽(201)，第一通槽沿锚杯的轴向同轴贯穿锚杯；分片式夹片的外表面为一端直径大、另一端直径小的圆锥形结构，使分片式夹片同轴嵌装在锚杯的第一通槽内；分片式夹片内形成有等径的第二通槽(301)，使FRP筋通过第二通槽同轴贯穿锚杯和分片式夹片；紧固件夹紧在FRP筋在自由端上，且紧固件通过垫片压紧在分片式夹片的大头端上。本发明能够解决现有技术中FRP筋容易在切口处疲劳损坏、夹片无法及时跟进而导致锚固效果、粘结操作不便的问题。
