Detailed description of the invention
Embodiment 1
The present embodiment is a kind of bridge CFRP muscle Group anchor for inhaul cable ground tackle, is separately mounted to the two ends of CFRP muscle drag-line, this ground tackle anchored by CFRP muscle.For the ease of understanding and describing, by vertically arranged to this ground tackle and corresponding CFRP muscle (omission of lower section length), as shown in the figure, this ground tackle includes anchor cup 1, anchor cup 1 has the passage of upper and lower both ends open, and anchor cup has been connected below connecting cylinder 17 and PE protective jacket 18, is cased with nut 19 outside anchor cup 1.One end of CFRP muscle 11 enters in anchor cup 1 after sequentially passing through PE protective jacket 18 and connecting cylinder 17 from the bottom to top, and in anchor cup 1, CFRP muscle 11 is anchored.
The concrete anchor structure of CFRP muscle 11 is shown in Fig. 1, upper and lower sub-wire end plate 2,3 it is provided with in the passage of anchor cup 1, upper and lower sub-wire end plate 2,3 is respectively close to the suitable for reading of anchor cup 1 and end opening, between upper and lower sub-wire end plate 2,3, there are two sub-wire dividing plates 4, the quantity of sub-wire dividing plate 4 can adjust according to specifically used environment, is not limited to two in the present embodiment.The end of CFRP muscle 11 is from the bottom to top through lower sub-wire end plate 3, two sub-wire dividing plate 4 and upper sub-wire end plate 2, then by the rubber ring 9 on the upper surface being positioned at upper sub-wire end plate 2 by CFRP muscle termination stirrup, rubber ring 9 prevents CFRP muscle termination impaired, that namely goes up sub-wire end plate 2 at the place suitable for reading of anchor cup 1 is arranged over end cap 16, and CFRP muscle termination is enclosed in anchor cup 1 so that it to be protected by end cap 16.Namely pass through of course for CFRP muscle is carried out sub-wire, upper and lower sub-wire end plate 2,3 and sub-wire dividing plate 4 all have the sub-wire hole 5 for CFRP muscle traverse, the space formed by upper and lower end plate and anchor cup 1 inwall is divided into three filled chambers 6 by two sub-wire dividing plates 4, is filled with colloid in filled chamber 6.Upper and lower sub-wire end plate 2,3 is set in anchor cup 1 and sub-wire dividing plate 4 is easy to that CFRP muscle is carried out sub-wire and is fixed, and multiple filled chamber will be separated out in ground tackle, in different filled chambers, add the colloid of different performance, by the colloid of different performance by bonding for CFRP muscle.That is, colloid composition or content in each filled chamber 6 are different, such as filling epoxy resin iron ore epoxy glue equal in three filled chambers 6, but iron ore content is different, the iron ore content of the epoxy resin iron ore epoxy glue in the filled chamber of bottom is minimum, the iron ore content of the epoxy resin iron ore epoxy glue of a middle filled chamber is slightly higher, the iron ore content of the epoxy resin iron ore epoxy glue in the filled chamber of the top is the highest, namely the iron ore content of each filled chamber gradually rises from the bottom to top, colloid rigidity is incrementally increased to ground tackle upper end by ground tackle lower end, thus adapting to CFRP muscle anchoring loading characteristic, improve the anchoring bonding force of CFRP muscle.
As it is shown in figure 1, namely the end opening place of anchor cup 1 descends the lower section of sub-wire end plate 3 to have sub-wire damping block 7, sub-wire damping block 7 is made up of rubber elastomeric material, and CFRP muscle is upward through lower sub-wire end plate 3 again after sub-wire damping block 7.This sub-wire damping block 7 is except carrying out sub-wire to CFRP muscle, it is also possible to prevent CFRP muscle failure by shear.
As shown in Fig. 4-7 and Fig. 9, Figure 10, it is provided with packing ring 8 in the sub-wire hole 5 of upper and lower sub-wire end plate 2,3 and sub-wire dividing plate 4, the Internal and external cycle of packing ring 8 contacts with CFRP muscle 11 and sub-wire hole 5 respectively, packing ring 8 clamps CFRP muscle, packing ring 8 has certain elasticity thus allowing the Free Transform of CFRP muscle trace, it is to avoid cut damage or disrumpent feelings in Cable forces in CFRP muscle installation process.
In order to improve the bonding force between the colloid in filled chamber and filled chamber, anchor cup 1 inwall corresponding with each filled chamber 6 is the up big and down small conical surface, and the conical surface improves the bonding force of colloid and anchor cup 1, has also been increased by ground tackle anchor force.
In anchor cup 1 inwall correspondence, lower sub-wire end plate 2, 3 and the installed position of sub-wire dividing plate 4 be provided with step 10, when the conical surface of all filled chambers is on same taper seat, step 10 is four the inside bulge loops being on taper seat, when the conical surface of different filled chambers is on different taper seats, namely when the bus of the conical surface of different filled chambers is not collinear, the namely state shown in Fig. 1, step 10 is the ring surface of the level formed between the bottom of the conical surface and the top in other faces adjacent, by step 10 on corresponding, lower sub-wire end plate 2, 3 and sub-wire dividing plate 4 axially position, and the diameter of bore that formed of the internal diameter of step 10 and step is less than on corresponding, lower sub-wire end plate 2, 3 and the external diameter of sub-wire dividing plate 4, structure is sealed so that being formed between each filled chamber.
As illustrated in figs. 2 through 8, the side face of upper and lower sub-wire end plate 2,3 and sub-wire dividing plate 4 is provided with arc convex 12, after upper and lower sub-wire end plate 2,3 and sub-wire dividing plate 4 are positioned on corresponding step 10, the screw 13 through respective arc convex upper and lower sub-wire end plate 2,3 and sub-wire dividing plate 4 are connected with corresponding step 10.
The inwall of anchor cup 1 is had the arc groove 14 embedded for corresponding arc convex 12 by the upper end of each step 10 to corresponding step, the axial length of arc groove 14 is more than corresponding arc convex 12, following sub-wire end plate 3 is example, from top to bottom lower sub-wire end plate 3 is put in the process on its corresponding step 10, lower sub-wire end plate 3 enters arc convex 12 thereon after the filled chamber 6 of bottom, initially enter the arc groove 14 in this filled chamber 6, by this arc groove 14, arc convex 12 is led, until lower sub-wire end plate 3 is resisted against on the step of lower section, both wire sub-panel can have been fixed, can determine that again orientation, sub-wire hole, it is easy to the fixed installation of CFRP muscle.Except the arc groove 14 guide effect when corresponding upper and lower sub-wire end plate 2,3 and sub-wire dividing plate 4 play installation, arc groove 14 also add the area of filled chamber inwall, therefore adds the anchor cup anchor force to colloid and CFRP muscle.
As Figure 4-8, upper sub-wire end plate 2 and sub-wire dividing plate 4 are provided with passage 15.Passage 15 can ensure that colloid perfusion density, increases the bonding force between colloid and muscle material, and reduces the deformation of the colloid after Cable forces.
