Abstract
The utility model discloses a composite type anchor group for FRP (fiber reinforce plastic) ribs. The FRP ribs penetrate through a metal barrel with a certain length, assembly glue is injected into the metal barrel, and the metal barrel is plugged by an end plug, so that FRP rib assembly pieces are formed. After maintenance, the assembly pieces are respectively assembled with clamping pieces, multi-hole anchor rings and anchor backing plats, and can be tensioned after being previously tightened. The anchor device is high in anchoring efficiency, and compact in structure, so that the FRP ribs is applicable to the prestress structure and the strengthening engineering.
Description
Technical field
The utility model relates to a kind of many anchor devices that receive lacing wire (rope), especially simultaneously the compound anchor device of many FRP muscle of anchoring (fibre reinforced composites).
Background technology
The domestic seat of honour CFRP cable stayed-cable bridge that is positioned at Jiangsu University adopted " straight tube add inner cone " binding type ground tackle (document is seen: the experimental study of CFRP suspension cable ground tackle (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. civil engineering journal, 2007; (1): 54-58)); This binding type ground tackle can carry out effective anchoring to many FRP muscle (rope) simultaneously, but anchorage length is bigger, uses inconvenience; Even stressed being difficult to of FRP muscle controlled; When single FRP muscle destroys, can't singlely change.
Summary of the invention
Existing many binding type FRP muscle ground tackle anchorage lengths are bigger in order to overcome, single muscle even stressedly be difficult to control, deficiency that can't single muscle; The utility model provides compound crowd's anchor device; This ground tackle not only can carry out effective anchoring to many FRP muscle simultaneously; Have short bond-anchorage length, and it is stressed evenly to control single FRP muscle during stretch-draw; When single muscle material destroys, can singlely change muscle.
The technical scheme that the utility model adopts is: this compound crowd's anchor comprises anchor plate, the porous anchor ring, and metal cylinder, adhesive glue, intermediate plate, end is stifled.Metal cylinder is straight tube, and inwall has the roughened of fine thread.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, blocks the port of metal cylinder with end.Intermediate plate is the equal portions three-chip type, and the sharper end of intermediate plate has chamfering, with the contacted inwall of metal cylinder the tooth line is arranged.Combine for wedge shape between porous anchor ring and the intermediate plate.There is 0.1 ° ~ 0.5 ° differential seat angle in the wedge shape inclination angle of intermediate plate between intermediate plate and porous anchor ring between 3 ° ~ 6 °.
After the maintenance, many composite membeies are assembled with intermediate plate, porous anchor ring, anchor plate respectively, got final product stretch-draw behind the pretension.The protective effect of metal cylinder has avoided crushing the FRP muscle, and simultaneously, the inner cone effect of intermediate plate can postpone the bond damage of load-bearing end adhesive glue and muscle material, improves bonding whole structure and anchoring efficient, reduces bond length.Through the adjustment pretightning force, make the FRP muscle evenly stressed.When single FRP muscle is disrumpent feelings, withdraw from intermediate plate and muscle material, change separately.
The beneficial effect of the utility model is: this compound crowd anchor 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 adjust the pretightning force size, make the FRP muscle evenly stressed; When single muscle material destroys, can change separately.

The specific embodiment
Fig. 1 is the vertical section constructional drawing of compound crowd's anchor embodiment, and this ground tackle comprises anchor plate 2, porous anchor ring 3, metal cylinder 4, adhesive glue 5, intermediate plate 6, end stifled 7 etc.Metal cylinder 4 is straight tube, and inwall has the roughened of fine thread.Metal cylinder 5 cross sections are circular, and FRP muscle 1 is positioned at the center, and intermediate gaps is filled with adhesive glue 5.
Fig. 2,3 is I-I left view of Fig. 1, and two kinds of embodiments of porous anchor ring are circle and rectangle.In the circular anchor ring of embodiment one, anchor hole is every at a distance from certain angle, evenly arranges.In the rectangle anchor ring of embodiment two, the anchor hole spacing equates, evenly arranges.
Fig. 4,5 is the intermediate plate constructional drawing, and intermediate plate 6 is a three-chip type, and 3 differential seat angles that have 0.1 ° ~ 0.5 ° of porous anchor ring.Intermediate plate 6 front ends have chamfering, with metal cylinder 4 contacted inwalls the tooth line are arranged.
In the implementation process,, inject adhesive glue 5 therebetween,, form FRP muscle composite member with stifled 7 shutoff of end with the metal cylinder 4 that FRP muscle 1 one ends pass.After the maintenance, again with many composite membeies respectively with 2 assemblings of intermediate plate 6, porous anchor ring 3, anchor plate, the clip position of intermediate plate 6 should be positioned at metal cylinder 4 load-bearing ends, apply pretightning force after, can carry out integral tension.
