Abstract
The utility model discloses a composite anchor for an FRP (fiber reinforce plastic) rib. The FRP rib penetrates through a metal barrel, assembly glue is injected into the metal barrel, and end plugs are used for positioning and plugging, so that an FRP rib assembly is formed. After maintenance, a clamping piece, a round-head anchor ring and an anchor plate are assembled on the assembly, and the assembly is tensile after pre-tightened. The anchor is high in anchoring efficiency, compact in structure and short in anchoring length, and the FRP rib can be applied to pre-stressed structures and strengthening works.
Description
Technical field
The utility model relates to the compound anchor device of the single FRP muscle of a kind of anchor device that receives lacing wire, especially anchoring (fibre reinforced composites).
Background technology
The horizontal shear strength of material of FRP muscle (fibre reinforced composites) is lower, and present existing FRP muscle ground tackle mainly contains bonded and clipping.Clipping ground tackle is prone to produce circumference stress to be concentrated, and causes the muscle material to crush destruction, and anchoring efficient is low.
The domestic seat of honour CFRP cable stayed-cable bridge that is positioned at Jiangsu University has adopted " straight tube adds internal cone type ", and the binding type ground tackle (see: the research (Lv Zhitao of domestic seat of honour CFRP cable stayed-cable bridge by document; The plum sunflower. civil engineering journal, 2007, (1): 54-58)); This binding type ground tackle can carry out effective anchoring to the FRP muscle; But anchorage length is bigger, and complex process is used inconvenience; During stretch-draw, the FRP muscle is prone to take place bending to be destroyed with eccentric.
Summary of the invention
Existing single FRP muscle ground tackle anchoring efficient is not high in order to overcome, anchorage length is big, be prone to take place the deficiency that bending and eccentric tension destroy during stretch-draw; The utility model provides a kind of compound anchor device that combines existing ground tackle construction features; This ground tackle not only can carry out effective anchoring to the FRP muscle; Have short bond-anchorage length, and when stretch-draw, can adjust the ground tackle angle voluntarily, prevent that the bending of muscle material from destroying with eccentric.
The technical scheme that the utility model adopts is: this compound ground tackle comprises anchor slab, round end anchor ring, intermediate plate, metal cylinder, and adhesive glue, end block up; The round end radius of round end anchor ring equates with the hemispherical groove radius of anchor slab, and the smooth surface of round end anchor ring and anchor slab, fits closely.The sharper end of intermediate plate has chamfering, with the contacted inwall of metal cylinder the tooth line is arranged.For wedge shape combines, there is 0.1 ° ~ 0.5 ° differential seat angle in the wedge shape inclination angle of intermediate plate between intermediate plate and round end anchor ring between 3 ° ~ 6 ° between round end anchor ring and the intermediate plate.The metal cylinder cross section is circular straight tube, and the FRP muscle is positioned at the center of metal cylinder, and the intermediate gaps between FRP muscle and the metal cylinder is filled with adhesive glue.End is stifled, and a through hole is established in the centre for circular, and through-hole diameter is greater than FRP muscle external diameter. Stifled circumferentially every of end establishes a screw at a distance from 90 ° fixes the stifled and metal cylinder of end.
The FRP muscle passes the metal cylinder of certain-length, injects adhesive glue therebetween, and by the stifled location of end, shutoff, forms FRP muscle composite member.After the maintenance, on composite member, assemble intermediate plate, anchor ring, anchor slab, get final product stretch-draw behind the pretension.Because the effect of metal cylinder, the circumference stress that weakened is concentrated, and avoids crushing the FRP muscle.Simultaneously, the inner cone effect of intermediate plate has postponed the bond damage of load-bearing end adhesive glue and muscle material, has improved bonding whole structure and anchoring efficient.The anchor ring front end is made hemispherical, and under the stretching force effect, ground tackle is the adjustment angle automatically, makes the FRP muscle be in axial tension, avoids the bending of muscle material to destroy with eccentric.
The beneficial effect of the utility model is: this compound ground tackle circumference stress that can weaken is concentrated, and improves the bonding mass action, obtains better anchoring efficient, reduces the length of anchor device.Simultaneously, can avoid the crushing and bend of muscle material, eccentric destruction.This ground tackle structure is compact, easy to use.

The specific embodiment
Fig. 1 is the vertical section constructional drawing of compound ground tackle embodiment, and this ground tackle comprises anchor slab 2, round end anchor ring 3, intermediate plate 4, metal cylinder 5, adhesive glue 6, end stifled 7 etc.The round end radius of round end anchor ring 3 equates with the hemispherical groove radius of anchor slab 2, and smooth surface, fits closely.Intermediate plate 4 front ends have chamfering, with the contacted inwall of metal cylinder the tooth line are arranged.3 differential seat angles that have 0.1 ° ~ 0.5 ° of intermediate plate 4 and round end anchor ring.Metal cylinder 5 is straight tube, and inwall has the roughened of fine thread.
Fig. 2 is I-I sectional view, and metal cylinder 3 cross sections are circular, and FRP muscle 1 is positioned at the center, and intermediate gaps is filled with adhesive glue 6, and adhesive glue 6 needs maintenance to solidifying fully.
Fig. 3 is the stifled constructional drawing of end, and end stifled 7 is circular, and a through hole is established in the centre, is positioned at the center in order to guarantee the FRP muscle, and through-hole diameter is more bigger than FRP muscle external diameter.Every establish a screw 8 at a distance from 90 ° all around, in order to fix.
In the implementation process,, inject adhesive glue 6 therebetween, will hold stifled 7 to be fixed in metal cylinder 5 two ends, form FRP muscle composite member the metal cylinder 5 that FRP muscle 1 passes certain-length.After the cured, on composite member, assemble intermediate plate 4, round end anchor ring 3, anchor slab 2 successively, the clip position of intermediate plate should be positioned at metal cylinder 5 load-bearing ends, after applying pretension on the intermediate plate 4, can carry out stretch-draw.
