Abstract
The invention discloses an efficient anti-sliding steel strand stay cable saddle, and belongs to the technical field of bridge structures. The stay cable saddle comprises an anchor bearing plate, a sleeve, deviators, a filling material and a flexible metal strap. The number of the deviators is consistent to that of steel strands in a stay cable, the periphery of each deviator is circular, the upper part and the lower part of the inner wall of each deviator are arc with different radiuses, and the middle of the inner wall of each deviator has a special-shaped structure of a diagonal plane. In addition, a large half circle of the flexible metal strap is arranged on the low middle part of the inner wall of each deviator, when the steel strands correspondingly and independently penetrate through the deviators, the flexible metal straps are extruded and then deform, and therefore, the area of a part, which is in contact with the steel strands, of the flexible metal strap is increased. Abrasion of the steel strand can be reduced, the force of friction of the steel strand is increased, sliding of the steel strand due to the unbalanced force on the two sides of a bridge tower can be prevented in a running process of the stay cable, and therefore, the safety of the structure is improved. Each steel strand in the stay cable can be changed independently, and the efficient anti-sliding steel strand stay cable saddle has wide application prospect.
Description
Technical field
The present invention relates to a kind of steel strand stay cable cable saddle of efficient resistant slide, belong to bridge structure technical field.
Background technology
With the continuous increase of the magnitude of traffic flow, the steel strand stay cable to cable-stayed bridge proposes new requirement, is first oblique
Security of the drag-line during runing, i.e. steel strand wires in suspension cable can not produce sliding in cable saddle；Secondly suspension cable is in dimension
Convenience during shield, i.e., on the premise of the uninterrupted traffic to suspension cable in each steel strand wires carry out single replacing.
For the cable-stayed bridge cable using steel strand wires, due to the techniques such as tensioning, during bridge military service, often
Certain root or a few steel strand wires premature breakdowns in some drag-lines occurs, this is accomplished by being changed.And whole Shu Jinhang is more
Changing will have that influence normal traffic and maintenance cost are high, also be unfavorable for not damaging being continuing with for steel strand wires, make
Into the waste of efficient resource.Additionally, suspension cable is during operation, and when in Sarasota both sides, load is not waited, the oblique pull of cable saddle both sides
There is energy imbalance in the Suo Li of rope, the steel strand wires in drag-line slide under the imbalance pulling force effect of both sides in cable saddle, will
Produce abrasion.After the corrosion prevention film on steel wire top layer is destroyed, in high-stress state, it is easier to fatigue rupture, easily influence
Bridge and the safety of driving.
Therefore in the urgent need to a kind of steel strand stay cable cable saddle of efficient resistant slide, can be prevented during suspension cable operation
Steel strand wires slide and can realize that the steel strand wires in suspension cable single can be changed, and can improve the stress of steel wire in steel strand wires,
Avoid being contacted with the point of sub-wire inside pipe wall on cross section.
The content of the invention
It is an object of the invention to solve above-mentioned the deficiencies in the prior art and problem, there is provided a kind of efficient antiskid
The steel strand stay cable cable saddle of shifting.
The present invention provide a kind of efficient resistant slide steel strand stay cable cable saddle, including steel strand wires, anchor plate, sleeve,
Sub-wire pipe, inserts and flexible metaltape, the radical of sub-wire pipe are identical with the steel strand wires radical in suspension cable, and steel strand wires are independently worn
Cross corresponding sub-wire pipe, and sub-wire pipe is that periphery is circle, the upper and lower part of inwall is the different circular arc of radius, it is upper it is big under
Small, middle part is the polymorphic structure of scarf, and the middle and lower part of sub-wire inside pipe wall is disposed with the flexible metaltape of big half-turn.Flexible metaltape increases
Big contacts area of the steel strand wires with sub-wire pipe, steel strand wires change and are and soft gold with the point contact of sub-wire inside pipe wall on cross section
Belong to the face contact of band.Special-shaped and independent sub-wire pipe can not only prevent the sliding of steel strand wires, be also convenient for single replacing steel strand wires.
The security of bridge is not only increased, the wasting of resources is it also avoid.
Further, the material of described flexible metaltape is tin, and when steel strand wires pass through sub-wire pipe, flexible metaltape is squeezed
Deform, realize the expansion of steel strand wires field of load on cross section, also increase the resistant slide ability of steel strand wires.
Further, the material of sub-wire pipe is high intensity aluminium, by slight deformation can occur after the extruding of steel strand wires.
And aluminium is easy to be processed into various abnormity components, facilitates the manufacture of sub-wire pipe.
Further, inserts is modified epoxy resin, and modified epoxy resin slurry filling is in sleeve and sub-wire pipe
Gap and solidify.Inserts is poured into the gap between sleeve and sub-wire pipe and solidifies, and sleeve and sub-wire pipe is formed one
Individual entirety.
Compared with prior art, the invention has the advantages that：After flexible metaltape under steel strand wires, in cross section
On, steel strand wires become and are contacted as the face with flexible metaltape contacts with putting for sub-wire inside pipe wall, it is to avoid the abrasion of steel wire；It is special-shaped and only
Vertical sub-wire pipe, makes the steel strand wires in suspension cable can be with single replacing, and its material is easy to manufacture for aluminium, can there is slight after stress
Deformation, further improves the stress of steel strand wires；Flexible metaltape improves the anti-slipping property energy of steel strand wires, can prevent oblique pull
During Suo Yunying, because of steel strand wires sliding caused by the out-of-balance force of bridge tower both sides.
