Abstract
The utility model provides a kind of flexible support structure of the aerial express occupation bridge of suspension type, belongs to bridge structure design technical field.The girder of suspension bridge uses float system, does not set bearing at Sarasota, and the vertical sunpender near Sarasota is removed, is changed to 6 groups of oblique sunpenders, is in net distribution, and angle is 55~65 °.The vertical deflection that the utility model can clearly improve aerial express effect lower girder is linear, so that it is tended towards stability, reduces vibration, significantly increase ride comfort.
Description
Technical field
The utility model belongs to bridge structure design technical field, is related to the structure optimization of suspension bridge, is related specifically to
A kind of 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
The lower section in road travels, and vehicular load is smaller, thus the occupation bridge for carrying the aerial express of suspension type mostly use 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, so that the traveling of vehicle is seemed 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.
Utility model content
The utility model provides a kind of flexible support structure of the aerial express occupation bridge of suspension type, can make vehicle row
Main Girder Deflection caused by sailing is linear more to be flattened out slow, substantially increases comfort by bus.
The technical solution of the utility model：
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 utility model：By at Sarasota girder vertical rigidity reduce, in across girder it is vertically rigid
Degree is close, when the aerial express of suspension type by when, greatly reduce car body fluctuating quantity, reduce vibration, improve by bus
Comfort.The utility model is easy for construction, need not increase additional labyrinth, only by optimizing the sunpender near Sarasota
Arrangement can be realized.
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 implementation mode
Below in conjunction with technical solution and attached drawing, specific embodiment of the present utility model is described in detail.
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)
1. a kind of flexible support structure of the aerial express occupation bridge of suspension type, which is characterized in that the girder (2) of suspension bridge is in bridge
