Abstract
The present invention provides a kind of flexible support structures of the aerial express occupation bridge of suspension type, belong to bridge structure design technical field.The girder of suspension bridge uses float system, does not set bearing, and the vertical sunpender near Sarasota is removed at Sarasota, is changed to 6 groups of oblique sunpenders, and in net distribution, angle is 55~65 °.The vertical deflection that the present invention can clearly improve aerial express effect lower girder is linear, it is made to tend towards stability, reduces vibration, significantly increases ride comfort.
Description
Technical field
The invention belongs to bridge structure design technical fields, are related to the structure optimization of suspension bridge, are related specifically to one kind
The flexible support structure of the aerial express occupation bridge of suspension type.
Background technology
The aerial express of suspension type is a kind of novel vehicles, is usually used in Scenic Spots, vehicle hanging is in special-purpose vehicle
Road lower section traveling, vehicular load is smaller, thus carry the aerial express of suspension type occupation bridge use more suspension bridge form with
Increase the span ability of bridge.But the rigidity of suspension bridge is smaller, and vehicle causes the displacement of girder larger when passing through, but works as vehicle
When driving near Sarasota, since girder is supported on the bearing at Sarasota, be equivalent to rigid support, thus vehicle have it is larger
Vibration, make the traveling of vehicle seem not enough steady.The method for improving girder vertical rigidity at present is to use Polyfunctional lever mechanism,
It constructs complexity, and cost is high, and larger obstruction is produced for the aerial express of Spread in China suspension type.
Invention content
The present invention provides a kind of flexible support structures of the aerial express occupation bridge of suspension type, and vehicle can be made to travel institute
The Main Girder Deflection of generation is linear more to be flattened out slow, substantially increases comfort by bus.
Technical scheme of the present invention：
A kind of flexible support structure of the aerial express occupation bridge of suspension type, the girder 2 of suspension bridge at bridge tower position not
If traditional bearing；Vertical conventional sunpender 4 near bridge tower replaces with flexible support structure 5, and flexible support structure 5 is in netted knot
Structure is made of multigroup oblique sunpender intersection；
Oblique sunpender is 6 groups in the flexible support structure 5, and the angle of inclination of oblique sunpender and horizontal plane is 55~65 °.
The effect and benefit of the present invention：By at Sarasota girder vertical rigidity reduce, in across girder vertical rigidity connect
Closely, when the aerial express of suspension type by when, greatly reduce car body fluctuating quantity, reduce vibration, improve by bus relax
Adaptive.The present invention is easy for construction, does not need to increase additional labyrinth, only can by the sunpender arrangement optimized near Sarasota
To realize.
Description of the drawings
Fig. 1 is a kind of flexible support structure figure of the aerial express occupation bridge of suspension type.
In figure：The aerial express of 1 suspension type；2 girders；3 main push-towing ropes；4 conventional sunpenders；5 flexible support structures.
Specific embodiment
Below in conjunction with the specific embodiment of technical solution and attached drawing, in detail the narration present invention.
Suspension Bridges are arranged as 70m+200m+70m, and girder 2 is steel construction, cross-sectional area 0.13m2, two main push-towing ropes
Sectional area be 0.1m2, hoist cable cross-sectional area is 0.005m2, spacing is 5m, removes six groups near bridge tower vertically conventional sunpenders
4, it is replaced with six groups of oblique sunpenders, and tiltedly sunpender is arranged to web form, angle is 55~65 °.It is main under identical load action
The vertical deflection of beam 2 has obtained apparent improvement, reduces vibration, improves comfort by bus.
Claims (2)
