Abstract
The invention discloses a carbon fiber cable anchor anchoring connection structure which comprises a carbon fiber cable and an anchor, wherein the carbon fiber cable is provided with a first stepped end part, the first end part contracts towards center radially in a stepped manner to form multiple sections of compression splice parts; the anchor comprises multiple compression splice pipes which are compressed and spliced with the stepped end parts, the compression splice pipes are correspondingly compressed and spliced with the various sections of compression splice parts in sequence and are connected end to end in sequence, the end part of the carbon fiber cable is designed into an end part of a stepped structure, the multiple compression splice pipes are correspondingly compressed and spliced with the end part of the stepped structure in sequence, so as to improve the compression splice area between the carbon fiber cable and the compression splice pipe, thereby increasing the anchoring force between the carbon fiber cable and the anchor, and solving the engineering problem that large-size flexible carbon fibers cannot be effectively connected with the anchor, thus the carbon fiber cable may be used in engineering.
Description
Technical field
The present invention relates to inhaul cable anchorage structure technical field, particularly to a kind of CFRP cable anchorage anchor connection structure.
Background technology
At present, CFRP cable has been widely used in the occasions such as bridge, building, electric power overhead wire, existing CFRP cable is typically in the way of crimping with anchorage to be connected, will penetrate in the rope hole of anchorage and crimp in CFRP cable end, it is generally only the version that monolayer crimping is fixing, owing to structure limits, it is difficult to be applicable to the connection of big specification (large area) CFRP cable.
Summary of the invention
The technical problem to be solved is to provide a kind of compact conformation, stable connection, is applicable to the CFRP cable anchorage anchor connection structure of big specification CFRP cable anchor connection.
By solving the technical scheme that above-mentioned technical problem is used: a kind of CFRP cable anchorage anchor connection structure, including CFRP cable, it has a stepped ends, and this stepped ends radially forms multistage pressure contact portion to center stepwise constriction；Anchorage, it includes the multiple pressure welding pipe fittings crimped with stepped ends, and each described pressure welding pipe fittings is corresponding in turn to be crimped on each section of pressure contact portion and head and the tail are sequentially connected and connect.
Further, described pressure welding pipe fittings includes that the aluminium hydraulic pressed connecting pipe being crimped on outside pressure contact portion and the capstan being socketed in outside aluminium hydraulic pressed connecting pipe, each described capstan head and the tail are sequentially connected and connect.
Further, the mode that each described capstan head and the tail are threaded connection is connected.
Further, it is additionally provided with lining between described pressure contact portion and aluminium hydraulic pressed connecting pipe.
Further, described aluminium hydraulic pressed connecting pipe outer wall end extends radially outwardly composition locating flange, and described capstan inwall end is formed for locating flange and embeds the location ring cavity of location.
Beneficial effect: in this CFRP cable anchorage anchor connection structure, CFRP cable end is designed to hierarchic structure shape end, pressure welding pipe fittings is designed to multiple, and be corresponding in turn to pressure welding pipe fittings accordingly be crimped on this hierarchic structure shape end, to improve the compression joint area between CFRP cable and pressure welding pipe fittings, thus increase the anchor force between CFRP cable and anchorage, the present invention is by the way of layer and section crimps, efficiently solve the engineering roadblock that the flexible CFRP cable of big specification (area) effectively cannot be connected with anchorage, make it utilize in engineering to be possibly realized.
Accompanying drawing explanation
The present invention is described further with embodiment below in conjunction with the accompanying drawings；
Fig. 1 is the cross-sectional view of the embodiment of the present invention；
Fig. 2 is the structural representation that in the embodiment of the present invention, pressure welding pipe fittings is connected.
Detailed description of the invention
Seeing figures.1.and.2, one CFRP cable anchorage anchor connection structure of the present invention, including CFRP cable 10, it has a stepped ends, and this stepped ends radially forms multistage pressure contact portion 11 to center stepwise constriction；Anchorage 20, it includes the multiple pressure welding pipe fittings crimped with stepped ends, and each pressure welding pipe fittings is corresponding in turn to be crimped on each section of pressure contact portion 11 and head and the tail are sequentially connected and connect.
Wherein, each pressure welding pipe fittings includes the aluminium hydraulic pressed connecting pipe 21 being crimped on outside pressure contact portion 11, the capstan 22 being socketed in outside aluminium hydraulic pressed connecting pipe 21, and the lining 23 being between aluminium hydraulic pressed connecting pipe 21 and capstan 22.
In the present embodiment, CFRP cable 10 end is level Four stepped ends, i.e. there are four sections of pressure contact portions 11, first lining 23, capstan 22 and aluminium hydraulic pressed connecting pipe 21 crimp on the pressure contact portion 11 of first paragraph overlaps successively, then lining 23, capstan 22 and aluminium hydraulic pressed connecting pipe 21 crimp on the pressure contact portion 11 of second segment overlaps the most successively, capstan 22 on the pressure contact portion 11 of first paragraph is connected with the capstan 22 on the pressure contact portion 11 of second segment, so repeats follow-up crimping process.Wherein, the connection between adjacent head and the tail capstan 22 is the most threaded.When whole pressure welding pipe fittings are corresponding in turn to be crimped on the stepped ends of CFRP cable 10, the compression joint area between CFRP cable 10 and pressure welding pipe fittings can be effectively improved, thus increase the anchor force between CFRP cable 10 and anchorage, solve the engineering roadblock that the flexible CFRP cable of big specification (area) effectively cannot be connected with anchorage so that it is utilize in engineering and be possibly realized.
As preferably, aluminium hydraulic pressed connecting pipe 21 outer wall end extends radially outwardly and constitutes locating flange 24, capstan 22 inwall end is formed for locating flange 24 and embeds the location ring cavity 25 of location, by locating flange 24 and coordinating of positioning ring cavity 25 so that it is internal that aluminium hydraulic pressed connecting pipe 21 is accurately positioned in capstan 22.
Above in conjunction with accompanying drawing, embodiments of the present invention are explained in detail, but the invention is not restricted to above-mentioned embodiment, in the ken that described technical field those of ordinary skill is possessed, it is also possible on the premise of without departing from present inventive concept, various changes can be made.
