Abstract
The utility model discloses a bonding type anchorage device used for an FRP (Fiber Reinforce Plastic) rib. The anchorage device comprises an anchorage barrel and end plugs and is characterized in that for the shape of the interior of the anchorage barrel, the two ends of the anchorage barrel are respectively designed to be a straight segment, the middle of the anchorage barrel is a continuous angle-variable pyramid segment, the end plugs with through holes are arranged at the two ends of the anchorage barrel, and an air outlet and an irrigation hole are arranged on the anchorage barrel. In the anchorage device, due to the design of the continuous pyramid segment in the anchorage barrel, the extrusion force of bonding colloid for the rib is improved, and the friction force of the surface of the FRP rib is enhanced, thereby obtaining higher anchorage efficiency and decreasing the length of the anchorage device. The anchorage device is simple in structure and convenient in use.
Description
Technical field
The utility model relates to a kind of anchor device that receives lacing wire (rope) material, the especially bonded anchor device of anchoring fiber muscle material (FRP).
Background technology
Jiangsu University's Western Hills pedestrian overcrossing is the cable stayed bridge that the domestic seat of honour adopts the CFRP suspension cable, has used " straight tube+internal cone type " CFRP bond type anchorage of designs such as plum sunflower at this bridge.This design be documented in CFRP suspension cable ground tackle experimental study (plum sunflower, Lv Zhitao, Zhang Jiwen. bridge construction; 2005,165 (4): 20-23) with the research of domestic seat of honour CFRP cable stayed-cable bridge (Lv Zhitao, plum sunflower. the civil engineering journal; 2007; (1): 54-58) be for sharp number that this bond type anchorage is constructed through " straight tube+internal cone type " and designed, and has realized the effective adhesive that has to the FRP muscle on the bond-anchorage body device of utility model pre-stress FRP muscle of ZL022426108; But the length of the type ground tackle is still bigger, is unfavorable for the raising of anchor tube tonnage.
Summary of the invention
In order to overcome the deficiency of prior art, the purpose of the utility model provides a kind of bond type anchorage with less anchorage length and effective anchoring FRP muscle material.
The technical scheme that the utility model adopts is: the FRP muscle is used bond type anchorage; Comprise that anchor tube and end are stifled, said anchor tube interior shape is: each flat segments of two ends, and the centre is the continuous cone section of varied angle; The end that said anchor tube two ends are provided with the band through hole blocks up, and said anchor tube is provided with venthole and irrigation hole.
Further, the inwall of said anchor tube is provided with internal thread, and said end is stifled to be centered close on the axis of anchor tube, the distribution that is centrosymmetric of the through hole on end is stifled.
Further, said anchor tube is provided with external screw thread and nut.
The beneficial effect of the utility model is: through the internal thread design of continuous cone section in the anchor tube and anchor tube, improve the extruding force of bonding colloid to the muscle material, strengthen the frictional force on FRP muscle surface, thereby obtain better anchoring efficient, reduced the length of anchor device.This ground tackle simple structure, easy to use.

Wherein: 1. nut, 2. anchor tube, 3. first end is stifled, and 4. second end is stifled, 5. first venthole, 6. irrigation hole, 7. second venthole, 8. external screw thread, 9. internal thread.
The specific embodiment
Fig. 1 is the vertical section constructional drawing of bond type anchorage embodiment, and this ground tackle comprises that nut 1, anchor tube 2, end are stifled etc., and anchor tube 2 interior shapes are: each flat segments of two ends, and centre be the continuous cone section of varied angle, two cone angles of boring section are respectively 8 ° and 6 °.The inwall of anchor tube 2 is provided with internal thread 9, and anchor tube 2 two ends are provided with stifled 3 and second end stifled 4 of first end of band through hole.Anchor tube 2 is provided with first venthole 5, second venthole 7 and irrigation hole 6, and anchor tube 2 is provided with external screw thread 8, and the nut 1 that cooperates with it is installed on the external screw thread 8.
Fig. 2, Fig. 3 are respectively I-I and II-II sectional view, and anchor tube 2 is a drum, and venthole 5,7 is a through hole, and nut 1 is arranged at stifled 3 one sides of first end of anchor tube 2, and the venthole diameter is 8mm among this embodiment, and the irrigation hole diameter is 28mm, and the screw thread specification is M3.
Like Fig. 4, shown in Figure 5, end is stifled to be disc, and the stifled marginal portion of end is littler than mid portion thickness, and edge thickness is 3mm in an embodiment, and the thickness of mid portion is 6mm; The stifled center of end is provided with a through hole, is that the diameter in the center of circle is on the circumference of 32mm 5 through holes to be set on average with this central through hole, and the angle of two adjacent through-holes is 72 °, and this angle can change according to the concrete mode of occupation of muscle material, but unsuitable too small.The diameter of through hole is 9mm, and the central through hole of stifled 3 and second end stifled 4 of first end is provided with on the central axis of anchor tube 2, and through hole is used to arrange FRP muscle material, than muscle material somewhat larger in diameter, can change according to the diameter of FRP muscle material.First end stifled 3 is only different at the diameter of mid portion with stifled 4 differences of second end in the present embodiment, so that assemble mutually with the two ends of anchor tube 2.
In the implementation process, pass the location, back FRP muscle material is stifled 3 from first end, anchor tube 2, second end stifled 4.Cementing medium is ready to, carries out encapsulating from irrigation hole 6, keep venthole up, all have colloid to overflow, accomplish encapsulating up to first venthole 5 and second venthole 7 with pressure encapsulating equipment.Same step is at the encapsulating of another ground tackle of FRP muscle material other end completion.Maintenance is screwed to nut 1 on the anchor tube 2 after accomplishing, and regulates nut 1 position and gets final product stretch-draw.When FRP muscle material was drawn, the existence of continuous cone section, inwall are provided with screw thread can improve the extruding force of bonding colloid to the muscle material, strengthens the frictional force on FRP muscle material surface, thereby obtains better anchoring efficient, has reduced the length of anchor device.
