Description
Technical field
The utility model relates to bridge, particularly a kind of single main push-towing rope system suspension bridge
Background technology
Suspension bridge is as a kind of bridge construction form, because its superior span ability and soft and graceful landscape effect have obtained using widely.Suspension bridge is made up of main push-towing rope, Sarasota, anchorage, hoist cable, bridge floor, and all loads all pass to main push-towing rope, pass to anchorage then through hoist cable.In order to resist wind load and to guarantee the torsional stability of bridge floor under monolateral vehicular load, traditional suspension bridge all adopts the form of two main push-towing ropes, and main push-towing rope is distributed in directly over the bridge floor beam both sides, connects girder through two vertical hoist cable faces.On the one hand, because runway all is positioned at two side sling scopes, so the visual field on both sides is penetrating inadequately, on the other hand, the suspension bridge of two main push-towing ropes does not have outstanding characteristic on landscape effect.
The utility model content
The utility model technical problem to be solved provides a kind of single main push-towing rope system suspension bridge, and runway two side view fields are broad, and bridge type is attractive in appearance, and helps reducing construction costs.
It is following that the utility model solves the technical scheme that its technical problem adopted:
A kind of single main push-towing rope system suspension bridge of the utility model comprises girder, main push-towing rope, and the bridge tower of main span both sides, abutment pier and anchor ingot, and it is characterized in that: said main push-towing rope quantity is single; Bridge tower inboard, both sides is oblique hoist cable district, is straight hoist cable district between the two skew back hoist cable districts; Said girder adopts sealing steel case beam, and the abutment pier in girder and the both sides bridge tower and the outside thereof forms continuous supporting system.
In technique scheme, said bridge tower adopts A type bridge tower, between its crossbeam and the girder tension compression bearing is set.
The beneficial effect of the utility model is, the girder both sides do not have hoist cable, and no any stopping of the visual field, the A shape bridge tower that single in addition main push-towing rope is unique is given the people smooth, grand sense, has unique landscape effect; It is half that the structure of single main push-towing rope has determined main push-towing rope radical and anchorage number all to lack than traditional two hoist cable suspension bridges, so can reduce construction costs effectively; On the classical suspension bridge bridge type of traditional two cables, two rope faces, carry out structural change, form the new type suspension bridge form of structure that tiltedly, directly makes up hoist cable, single main push-towing rope system, enriched the bridge type of suspension bridge as a new bridge construction form branch.
