Abstract
The utility model discloses a cured-on anchor device used to a plastic inhaul cable of fibrous reinforcement which is provided with a steel sleeve and a locating hole, wherein the steel sleeve is of a cylinder shape and the cavity is of a cone shape, inside which active powder concrete (RPC) is arranged and the bottom of the cavity is provided with a plurality of round holes, through which the inhaul cable passes and is located in the locating hole; the edges of the round holes take the shape of circular arc. As in the anchor device used a plastic inhaul cable of fibrous reinforcement, a plurality of round holes are arranged at the bottom of the circular arc-shaped slot and the edges of the round holes take the shape of circular arc without a right angled edge, when the plurality of plastic inhaul cables of fibrous reinforcement (FRP) are stressed, the inhaul cable smoothes exceedingly at the edge of round holes, with no damage or snap caused by the concentrated stress on the right angled-edge.
Description
Technical field:
The utility model relates to the bridge construction construction field, specifically refers to a kind of fibre reinforced plastics drag-line bond type anchorage that is used for.
Background technology:
Fibre reinforced plastics drag-line (FRP) is a kind of typical horizontal sight isotropic material, has the longitudinal strength height, and the low characteristics of transverse strength.The bond type anchorage of anchoring plurality of fibers reinforced plastic drag-line (FRP), comprise steel bushing, locating hole, steel bushing is the cylinder bodily form, and external surface has screw thread, and is with nut, in shaggy conical tank is arranged, bottom land has a plurality of circular holes, and many drag-lines pass circular hole, and is positioned on the locating hole, then RPC (RPC) is pressed in the steel bushing groove by grout hole, till RPC overflows from venthole.There is following problem in anchoring plurality of fibers reinforced plastic drag-line (FRP) bond type anchorage at present: the circular hole that is provided with at the bottom of the steel bushing cone tank, the circular hole edge is rectangular, rib is arranged, when the fibre reinforced plastics prestressed cable was stressed, drag-line was concentrated and is caused the drag-line damage or fracture in rib place, right angle, circular hole edge stress.
Summary of the invention:
When the purpose of this utility model is to provide a kind of plurality of fibers reinforced plastic drag-line (FRP) stressed, drag-line circular hole edge can stress concentrate and cause damaging or fracture be used for fibre reinforced plastics drag-line bond type anchorage.
The utility model purpose is achieved like this, this is used for fibre reinforced plastics drag-line bond type anchorage, comprise steel bushing, locating hole composition, steel bushing is the cylinder bodily form, and inner chamber is conical, and RPC (RPC) is arranged in the inner chamber, a plurality of circular holes are arranged at the bottom of the chamber, drag-line passes circular hole, is positioned on the locating hole, and described circular hole edge is circular-arc.
Described locating hole edge is circular-arc.
Because this is used for fibre reinforced plastics drag-line bond type anchorage, a plurality of circular holes are arranged at the bottom of its conical tank, the circular hole edge is circular-arc, there is not the right angle rib, when plurality of fibers reinforced plastic drag-line (FRP) is stressed, drag-line is smooth excessively in circular hole edge, can not concentrate and causes damage and fracture in right angle rib place stress.
Description of drawings:
Fig. 1 is for being used for fibre reinforced plastics drag-line bond type anchorage structural representation
Fig. 2 is a bond type anchorage working state structure schematic diagram
The specific embodiment:
With reference to figure 1---Fig. 2, this is used for fibre reinforced plastics drag-line bond type anchorage, comprises steel bushing 3, locating hole 1 composition, steel bushing 3 is the cylinder bodily form, external surface has screw thread, and is with nut 5, and inner chamber 10 is conical, RPC (RPC) 4 is arranged in the inner chamber 10, a plurality of circular holes 11 are arranged at the bottom of the chamber, and drag-line passes circular hole 11, is positioned on the locating hole 1, described circular hole 11 edges 9 are circular-arc, and described locating hole 1 edge 9 also is circular-arc.Drag-line 8 puts Thin-walled Aluminum sleeve pipe 7 at locating hole 1 and 10 end of conical internal cavity circular hole 11 sections.During use RPC (RPC) 4 is pressed in the steel bushing inner chamber 10 by grout hole 2, till RPC overflows from venthole 6, when plurality of fibers reinforced plastic drag-line (FRP) 8 is stressed, drag-line 8 at 9 places, circular hole edge smooth excessively, can stress do not concentrate and cause damage and fracture.
Claims (2)
1, a kind of fibre reinforced plastics drag-line bond type anchorage that is used for, comprise that steel bushing, locating hole, steel bushing are the cylinder bodily form, inner chamber is conical, RPC is arranged in the inner chamber, a plurality of circular holes are arranged at the bottom of the chamber, drag-line passes circular hole, be positioned on the locating hole, it is characterized in that: described circular hole edge is circular-arc.
2, the fibre reinforced plastics drag-line bond type anchorage that is used for according to claim 1, it is characterized in that: described locating hole edge is circular-arc.
