Specific embodiment
A specific embodiment of the invention is described in more detail below in conjunction with schematic diagram.According to following description and
Claims, advantages and features of the invention will become apparent from.It should be noted that attached drawing is all made of very simplified form and
Using non-accurate ratio, only for the purpose of facilitating and clarifying the purpose of the embodiments of the invention.
The present invention provides a kind of suspension cable transfer, and Fig. 1 is the suspension cable transfer that one embodiment of the invention provides
Schematic diagram, as shown in Figure 1, the suspension cable transfer include: saddle 1, sub-wire pipe positioning plate 2, sub-wire pipe 51, round tube 52,
Steel strand wires 53 and saddle body connecting flange 3, the saddle 1 are the curved pipe of rectangular in cross-section, and the saddle body connecting flange 3 is arranged
At 1 both ends of saddle, the round tube 52 is more and to be arranged at intervals in the saddle 1,52 both ends of round tube with it is described
Saddle body connecting flange 3 is fixedly connected, and the sub-wire pipe 51 is that three circular arcs surround the section to be formed in heart-shaped pipe, the sub-wire
Pipe 51 is arranged between the round tube 52 and tangent with three adjacent round tubes 52 respectively, and the steel strand wires 53 are clamped in institute
It states between two circular arcs opposite in sub-wire pipe 51, for fixing multiple sub-wires of the sub-wire pipe 51 and the round tube 52
Pipe positioning plate 2 is arranged at intervals between two saddle body connecting flanges 3.It is provided with described in confession on the sub-wire pipe positioning plate 2
The hole that sub-wire pipe 51 and the round tube 52 pass through, the position between the sub-wire pipe 51 and the round tube 52 pass through the sub-wire pipe
Positioning plate 2 is fixed.The sub-wire pipe 51 can also be welded to connect with the round tube 52, increase bonding strength, easy to operate, stress
Reliably.The saddle body connecting flange 3 is provided with the foramen cordiforme of the sub-wire pipe 51, and the sub-wire pipe 51 passes through the heart
Saddle body connecting flange 3 described in Kong Bingyu is fixedly connected.The saddle body connecting flange 3 and the steel strand wires 53 pass through guide section and mistake
Section connection drag-line is crossed, this is the prior art, and the application repeats no more.In existing suspension cable transfer, sub-wire pipe interval is set
It sets, slightly expanded concrete is perfused between sub-wire pipe with distractive load, and the present invention connects sub-wire pipe 51 using round tube 52, improves
The structural strength of suspension cable transfer alleviates weight, simultaneously as slightly expanded concrete need not be perfused, suspension cable is turned to
Device integral installation, simplifies construction technology, reduces construction cost.
Referring to Fig. 1, the saddle 1 has two pieces of opposite arc panels and two pieces of opposite plates to surround to be formed.Described two pieces
WELDING STUDS 4 is provided on the outside of opposite plate.The more sub-wire pipes 51, the round tube 52 and the steel strand wires 53 form sub-wire
Pipe boundling 5.Fig. 2 is the suspension cable transfer cross-section diagram that one embodiment of the invention provides, and referring to fig. 2, the sub-wire pipe 51 is
It is arranged between the round tube 52.Microdilatancy is perfused between the round tube 52 in 5 outside of 1 side wall of saddle and the sub-wire pipe boundling
It is fixedly connected between the round tube 52 and the side wall of the saddle 1 in 5 outside of concrete or the sub-wire pipe boundling.
Fig. 3 is the heart-shaped sub-wire pipe cross-section diagram that one embodiment of the invention provides, and referring to Fig. 3, three circular arcs include two phases
Pair clamping arc section 511, and connection arc sections of the opposite clamping arc section 511 of connection two, the three of the sub-wire pipe 51
It is connected smoothly between circular arc.The steel strand wires 53 are formed by more 531 twistings of steel wire, the steel strand wires and the sub-wire
511 inner wall of clamping arc section of pipe 51 is tangent, and the sub-wire pipe 51 is enable to block institute to the tangential reaction of the steel strand wires 53
State steel strand wires 53 formed it is self-locking.Existing sub-wire pipe is mostly that round or V-arrangement, circular sub-wire pipe are not capable of clamping the steel strand wires,
Cheng Qiaohou need to be perfused epoxy resin mortar in sub-wire pipe and carry out closing anchoring, since steel strand wires and sub-wire pipe are sticked to one by epoxy resin mortar
Block single cannot be adjusted tensioning, can only entire beam tension, multiply stretching construction difficulty is big and anti-slipping property can be bad, also gives
Steel hinge line replacement from now on brings certain difficulty.V-arrangement sub-wire pipe is the improvement to round sub-wire pipe, two straight lines of sub-wire pipe
Section clamping steel strand wires in turn ensure that steel is cut with scissors so that being both not necessarily to the perfusion epoxy resin mortar into inner tube in Cheng Qiaohou carries out closing anchoring
Line is parallel and does not interfere with each other, and it is also more convenient that the later period replaces steel strand wires.Then, the effective two straightways clamping steel of V-arrangement sub-wire twists
Line can not accomplish that the steel wire of steel strand wires as much as possible and straightway are tangent, and the stress of steel strand wires is poor.The present invention uses
Heart-shaped sub-wire pipe clamps steel strand wires with two arc sections, and steel strand wires uniform force can also eliminate certain internal stress.
In conclusion the suspension cable turns to dress in a kind of suspension cable transfer that one embodiment of the invention provides
Set includes: saddle 1, sub-wire pipe positioning plate 2, sub-wire pipe 51, round tube 52, steel strand wires 53 and saddle body connecting flange 3, the saddle
1 is the curved pipe of rectangular in cross-section, the saddle body connecting flange 3 setting at 1 both ends of saddle, the round tube 52 be more and
It is arranged at intervals in the saddle 1,52 both ends of round tube are fixedly connected with the saddle body connecting flange 3, the sub-wire pipe 51
Surround the section to be formed in heart-shaped pipe for three circular arcs, the sub-wire pipe 51 be arranged between the round tube 52 and respectively with phase
Three adjacent round tubes 52 are tangent, and the steel strand wires 53 are clamped between two circular arcs opposite in the sub-wire pipe 51, use
Two saddle bodies are arranged at intervals in multiple sub-wire pipe positioning plates 2 of the fixation sub-wire pipe 51 and the round tube 52 to connect
Between acting flange 3.
