Built-in anchorage type prestress FRP rib tensioning and anchoring device
The invention relates to a built-in anchorage type prestress FRP rib tensioning and anchoring device. The device comprises prestress FRP ribs, binding materials, steel sleeves, a screw rod, a nut, an annular steel washer and a circular anchor ring, wherein the two ends of the prestress FRP ribs are respectively inserted in opening ends of the steel sleeves at a tensioning end and an anchoring end, and are fixed by the binding materials; a closing end of the steel sleeve at the tensioning end is welded with a section of screw rod; the screw rod penetrates through the ring wall of the circular anchor ring at the tensioning end; the annular steel washer and the nut matched with the screw rod are mounted in the circular anchor ring; and a closing end of the steel sleeve at the anchor end penetrates through the ring wall of the circular anchor ring at the anchoring end, and is welded with the circular anchor ring. The device is suitable for FRP rib materials with various materials and various section forms, is simple in structure, low in cost and convenient for construction, and can be applied to concrete structural components built and reinforced by a prestress FRP rib technology.
