Abstract
The utility model discloses a kind of suspension bridge wind resistance rubber rope, including stiffening girder of suspension bridge, stiff girder is provided with hole, the both ends of rubber rope rope body are mounted on clasp, its one end is connected by the hole of clasp and stiff girder, other end connection anchorage is fixed on bank, and the both ends of stiff girder are symmetrical arranged rubber rope rope body.Described rubber rope rope body is high-damping rubber rope, and its surface is provided with protective layer.The utility model is improved on the basis of original wind resistance cable, and steel wire rope or steel strand wires are replaced with rubber rope, forms high-damping wind resistance cable.By the pre- pretensioning to rubber rope, fixed bridge floor position.When wind action makes bridge floor torsional deflection in bridge floor, two rubber ropes will produce antitorque moment resistance wind load.Under wind-force effect, damping capacity is consumed by swinging, makes bridge floor vibration more steady, is finally reached wind resistance purpose.
Description
Technical field
It the utility model is related to bridge construction field, more particularly to a kind of cable-stayed bridge, the structure of suspension bridge bridge floor wind resistance shake.
Background technology
As bridge span constantly increases, the flexibility of bridge is continuously increased, and vibration frequency constantly reduces, and the excitation to wind is more
Add sensitivity.Influence of the wind to suspension bridge, cable-stayed bridge can not be ignored.The wind resistance cable of suspension bridge has many forms, also have much on
The research of wind resistance cable.But wind resistance cable is essentially all based on steel wire rope or steel strand wires.Cord strength is bigger, although
Bridge floor position can be fixed very well, reduces the amplitude of bridge floor, but energy expenditure can not be fallen, but is produced on bridge span structure horizontal
To local assault load, increase bridge vibration frequency.Fatigue damage will be produced to bridge span structure a part under long duration of action.When
Wind speed is excessive, and the moment stress at wind resistance cable anchoring position is excessive, and fatigue rupture occurs in anchored end.
The content of the invention
A kind of suspension bridge wind resistance rubber rope provided by the utility model, damping capacity is consumed by swinging, vibrates bridge floor
It is more steady, it is finally reached wind resistance purpose.
In order to solve the above technical problems, technical scheme is used by the utility model：A kind of suspension bridge wind resistance rubber rope,
Including stiffening girder of suspension bridge, stiff girder is provided with hole, and the both ends of rubber rope rope body are mounted on clasp, and its one end passes through clasp
It is connected with the hole of stiff girder, other end connection anchorage is fixed on bank, and the both ends of stiff girder are symmetrical arranged rubber rope rope body, rubber
Glue rope rope body sets and is in tensioned state afterwards in place.With the across footpath increase of bridge, the anchor type of rubber rope can be flexibly more
Become, can also anchor on the auxiliary pier of korneforos.
Further, described rubber rope rope body is high-damping rubber rope, and its surface is provided with protective layer.
Further, the clasp latches for pyriform.
Further, the rubber rope rope body is provided with more, and every four ropes body is one group, is symmetricly set on puts more energy into two-by-two
The both ends of beam, and the both ends of suspension bridge are also symmetrical arranged.
Further, the angle of rubber rope rope body and suspension bridge gradually increases from suspension bridge centre to both ends.
When rubber rope rope body is installed, first its one end is connected with stiff girder, then the other end is tightened by prestressed stretch-draw
The anchorage on bank is fixed to afterwards.Its stretching process is needed into the symmetrical tensioning in beam body both sides.It will be put more energy into by the tension of rubber rope prestressing force
Liangping is firm fixed, the torsion for preventing bridge floor from occurring under wind action.Suspension bridge passes through rubber in transverse reciprocating swing process
Glue rope consumed energy.Rubber rope cost is relatively low, and it is convenient to change, and can regularly replace rope later.
The utility model is improved on the basis of original wind resistance cable, by steel wire rope or steel strand wires with rubber rope generation
Replace, form high-damping wind resistance cable.By the pre- pretensioning to rubber rope, fixed bridge floor position.When wind action is in bridge floor
When making bridge floor torsional deflection, two rubber ropes will produce antitorque moment resistance wind load.Under wind-force effect, consumed by swinging
Damping capacity, make bridge floor vibration more steady, be finally reached wind resistance purpose.
Brief description of the drawings
Fig. 1 is structural front view of the present utility model.
Fig. 2 is structure top view of the present utility model.
Fig. 3 is the structural representation of the utility model clasp and rubber rope rope body.
Embodiment
The utility model, but the scope of the requires of the utility model protection are further illustrated with reference to embodiment and accompanying drawing
It is not limited to the scope of embodiment statement.
As Figure 1-3, a kind of suspension bridge wind resistance rubber rope, including stiffening girder of suspension bridge 2, stiff girder 2 are provided with hole,
The both ends of rubber rope rope body 3 are mounted on clasp 1, and its one end is connected by clasp with the hole of stiff girder 2, other end connection anchor
Heavy stone used as an anchor 4 is fixed on bank, and the both ends of stiff girder are symmetrical arranged rubber rope rope body.
Preferably, described rubber rope rope body is high-damping rubber rope, such as uses natural latex rubber rope；Its surface is provided with
Nylon protective layer, avoid rubber rope sunshine and rain erosion.
Preferably, the clasp latches for pyriform, the optional Q390 of material.With some strength and with necessarily corrosion-resistant
Property.
Preferably, the rubber rope rope body 3 is provided with more, and every four ropes body is one group, is symmetricly set on puts more energy into two-by-two
The both ends of beam, and the both ends of suspension bridge are also symmetrical arranged.The angle of rubber rope rope body and suspension bridge from suspension bridge centre to
Both ends gradually increase.
Hole on stiff girder can preset in advance or later stage welding, when installing rubber rope rope body, by rubber rope rope body
One end is buckled on stiff girder, and the both ends of stiff girder are respectively mounted rubber rope rope body, the rubber rope at simultaneous tension stiff girder both ends
Rope body, is buckled on the anchorage on bank.By being in order to increase the torsional rigidity of stiff girder, no to the pre- pretensioning of rubber rope rope body
As for producing larger torsional deflection under being acted in wind-force.Meanwhile rubber rope rope body can be allowed to enter working condition in advance, micro-
With regard to energy can be absorbed under small displacement.When changing rubber rope rope body, first original wind cable lock can be removed, then symmetrically
Tensioning rubber rope, is anchored in two sides.
