Description
Technical field
The present invention relates to inhaul cable anchorage structure technical field, more particularly to a kind of CFRP cable anchorage anchor connection knot
Structure.
Background technology
At present, CFRP cable has been widely used in the occasions such as bridge, building, electric power overhead wire, existing carbon
Fiber drag-line is typically to be connected in a manner of crimping with anchorage, i.e., penetrates CFRP cable end in the rope hole of anchorage and carry out
Crimping, it is generally only the fixed structure type of individual layer crimping, because structure limits, it is difficult to fine suitable for big specification (large area) carbon
The connection of Wella rope.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of compact-sized, stable connection, suitable for big specification carbon fibre
The CFRP cable anchorage anchor connection structure of Wella rope anchor connection.
Technical scheme used by solve above-mentioned technical problem：A kind of CFRP cable anchorage anchor connection structure, bag
CFRP cable is included, it has a stepped ends, and the stepped ends radially form multistage pressure contact portion to center stepwise constriction；Anchor
Tool, it includes the multiple pressure welding pipe fittings crimped with stepped ends, and each pressure welding pipe fittings, which are corresponding in turn to, is crimped on each section of pressure contact portion
Upper and head and the tail are sequentially connected and connect.
Further, the pressure welding pipe fittings include the aluminium hydraulic pressed connecting pipe being crimped on outside pressure contact portion and the pulling force being socketed in outside aluminium hydraulic pressed connecting pipe
Pipe, each capstan head and the tail, which are sequentially connected, to be connect.
Further, the mode that each capstan head and the tail are connected through a screw thread is connected.
Further, it is additionally provided with bushing between the pressure contact portion and aluminium hydraulic pressed connecting pipe.
Further, the aluminium hydraulic pressed connecting pipe outer wall end, which extends radially outwardly, forms locating flange, the pulling force inside pipe wall end
Portion is formed with the positioning ring cavity for locating flange insertion positioning.
Beneficial effect：In this CFRP cable anchorage anchor connection structure, CFRP cable end is designed to hierarchic structure
Shape end, pressure welding pipe fittings are designed to multiple, and are accordingly corresponding in turn to pressure welding pipe fittings and are crimped on the hierarchic structure shape end,
To improve the compression joint area between CFRP cable and pressure welding pipe fittings, so as to increase the anchoring between CFRP cable and anchorage
Power, for the present invention by way of layer and section crimping, efficiently solving big specification (area) flexible CFRP cable can not be with
The engineering roadblock that anchorage is effectively connected, make it possible its in engineering using.
Brief description of the drawings
The present invention is described further with reference to the accompanying drawings and examples；
Fig. 1 is the cross-sectional view of the embodiment of the present invention；
Fig. 2 is the structural representation that pressure welding pipe fittings are connected in the embodiment of the present invention.
Embodiment
Referring to Figures 1 and 2, a kind of CFRP cable anchorage anchor connection structure of the present invention, including CFRP cable 10,
It has a stepped ends, and the stepped ends radially form multistage pressure contact portion 11 to center stepwise constriction；Anchorage 20, it includes
The multiple pressure welding pipe fittings crimped with stepped ends, each pressure welding pipe fittings be corresponding in turn to be crimped on each section of pressure contact portion 11 and head and the tail successively
It is connected.
Wherein, each pressure welding pipe fittings include the aluminium hydraulic pressed connecting pipe 21 being crimped on outside pressure contact portion 11, the pulling force being socketed in outside aluminium hydraulic pressed connecting pipe 21
Pipe 22, and the bushing 23 between aluminium hydraulic pressed connecting pipe 21 and pressure contact portion 11.
In the present embodiment, the end of CFRP cable 10 is level Four stepped ends, i.e., with four sections of pressure contact portions 11, first first
The pressure contact portion 11 of section covers upper bushing 23, capstan 22 and aluminium hydraulic pressed connecting pipe 21 and crimped successively, then in the pressure contact portion of second segment
11 also cover upper bushing 23, capstan 22 and aluminium hydraulic pressed connecting pipe 21 and are crimped, the capstan 22 on the pressure contact portion 11 of first paragraph successively
It is connected with the capstan 22 on the pressure contact portion 11 of second segment, so repeats follow-up crimping process.Wherein, adjacent head and the tail
Connection between capstan 22 is preferably to be threadedly coupled.The rank of CFRP cable 10 is crimped on when whole pressure welding pipe fittings are corresponding in turn to
When on terraced end, the compression joint area between CFRP cable 10 and pressure welding pipe fittings can be effectively improved, so as to increase carbon fiber
Anchor force between drag-line 10 and anchorage, solving big specification (area) flexible CFRP cable can not be carried out effectively with anchorage
The engineering roadblock of connection, make it possible its in engineering using.
Preferably, the outer wall end of aluminium hydraulic pressed connecting pipe 21, which extends radially outwardly, forms locating flange 24, the inwall end of capstan 22
Formed with the positioning ring cavity 25 for the insertion positioning of locating flange 24, pass through the cooperation of locating flange 24 and positioning ring cavity 25 so that
Aluminium hydraulic pressed connecting pipe 21 is accurately positioned in inside capstan 22.
Embodiments of the present invention are explained in detail above in conjunction with accompanying drawing, but the invention is not restricted to above-mentioned embodiment party
Formula, can also be before present inventive concept not be departed from the technical field those of ordinary skill possessed knowledge
Put that various changes can be made.
