Abstract
The invention discloses an efficient steel strand wire stay cable saddle and belongs to the technical field of bridge structures. The stay cable saddle comprises steel strand wires, anchor bearing plates, a sleeve, wire dividing tubes, a filling material and soft metal, wherein the number of the wire dividing tubes is the same as the number of the steel strand wires in the stay cable; the steel strand wires independently pass through the corresponding wire dividing tubes; the periphery of each wire dividing tube is circular; an upper part and a lower part of the inner wall of each wire dividing tube are shaped as arcs with different diameters; the upper part is large, the lower part is small, and a middle part is a special-shaped structure with a diagonal plane; the peripheries of the steel strand wires are coated with a circle of soft metal; the contact area is increased. According to the efficient steel strand wire stay cable saddle, single steel strand wire in the stay cable can be replaced; through a soft metal layer, the stress area of the steel strand wires is increased; meanwhile, the slippage resistance is improved; the slippage of the steel strand wires caused by unbalanced force on two sides of a bridge tower in the operation process of the stay cable can be avoided; the safety of the structure is improved; the efficient steel strand wire stay cable saddle has broad application prospects.
Description
Technical field
The present invention relates to a kind of efficient steel strand stay cable cable saddle, belongs to bridge structure technical field.
Background technology
The continuous increase of the magnitude of traffic flow, to the steel strand stay cable of cable-stayed bridge new requirement is proposed, and is first suspension cable
Steel strand wires in security during runing, i.e. suspension cable can not produce sliding in cable saddle；Secondly suspension cable is in the phase of maintenance
Between convenience, i.e., on the premise of 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 due to the techniques such as tensioning, during bridge is on active service, Jing is normal
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 there is a problem of affecting normal traffic and maintenance cost 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 sliding in cable saddle under the imbalance pulling force effect of both sides of the steel strand wires in drag-line, cross-section
Face and force-bearing situation of the sub-wire pipe in point-like contacts, will produce greatly abrasion.After the corrosion prevention film on steel wire top layer is destroyed,
High-stress state, is easier to fatigue rupture, easily affects the safety of bridge and driving.
Therefore in the urgent need to a kind of steel strand stay cable cable saddle of efficient resistant slide, can prevent during suspension cable operation
Steel strand wires sliding can realize that the steel strand wires in suspension cable single can be changed again, 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 steel
Twisted wire suspension cable cable saddle.
The present invention provide a kind of efficient steel strand stay cable cable saddle, including steel strand wires, anchor plate, sleeve, sub-wire pipe,
Inserts and soft metal layer, the steel strand wires radical in the radical and suspension cable of sub-wire pipe is equal, and steel strand wires are independently through correspondence
Sub-wire pipe, and the periphery of sub-wire pipe is circle, and the upper and lower of inwall is the different circular arc of radius, up big and down small, in
Portion for scarf polymorphic structure, one layer of soft metal layer of the steel tendon outer wrapping of steel strand wires.This programme increases steel strand wires week
The contact area on side, improve the stress of steel strand wires, it is to avoid the point contact on steel strand wires cross section.It is special-shaped and independent
Sub-wire pipe not only can prevent the sliding of steel strand wires, be also convenient for single replacing steel strand wires, not only increase the security of bridge,
Avoid the wasting of resources.
Further, the material of the soft metal layer of the periphery of steel strand wires is tin, is first to be pressed onto steel strand wires periphery in advance, afterwards
Sub-wire pipe is penetrated again.
Further, the material of sub-wire pipe be high intensity aluminium, by can occur after the extruding of steel strand wires it is slight deform,
Improve the stress of steel strand wires.
Further, inserts is modified epoxy resin, is modified epoxy resin slurry filling in sleeve and sub-wire
The gap of pipe simultaneously solidify to form.Sleeve and sub-wire pipe is set to form an entirety.
Compared with prior art, the invention has the advantages that：After steel strand wires parcel soft metal layer, in cross section
On, steel strand wires become and contact and contacted into the face with soft metal layer 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；Soft metal layer 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.Improve the security of structure, it is to avoid resource
Waste, have broad application prospects.
The structural representation of the steel strand stay cable cable saddle of Fig. 1 present invention.
The A-A profiles of Fig. 2 Fig. 1.
The sub-wire pipe of Fig. 3 present invention and the arrangement schematic diagram of steel strand wires.
Identify in figure：1- anchor plates, 2- sleeves, 3- sub-wire pipes, 4- inserts, 5- soft metal layers, 6- steel strand wires.
