Abstract
The utility model discloses the long overhanging crossbeam bridge structure of one kind, belong to bridge elongation technology field.The utility model provides a kind of long overhanging crossbeam bridge structure, and it mainly includes：Steel construction longeron, prestressed concrete crossbeam and steel reinforced concrete binding site.Wherein, steel structure bridge is connected by steel reinforced concrete binding site with prestressed concrete crossbeam.Bridge is longitudinally steel construction, can mitigate the suffered deadweight of bridge so that calculation of beam can pass through.Steel construction has higher deformability, can adapt to crossbeam due to length travel is caused to longeron caused by tensioning and loss of prestress influence.Steel construction also allows for increase longitudinal external prestressing during later stage bridge maintaining.Meanwhile, using prestressed concrete crossbeam, the rigidity of crossbeam is increased, vibratory sense of the bridge in vehicle traveling process is reduced, concrete has preferable durability.
Description
Technical field
The utility model is related to a kind of long overhanging crossbeam bridge structure, belongs to bridge elongation technology field.
Background technology
Further develop with the transport development in China city, interchange bridge, overpass have obtained widely should
With.Existing urban interchange is influenceed in city by many factors such as landform, atural object, underground utilities, in order that high
Design of building bridge meets the requirement of Route Plane and road construction boundary headroom, need to set at key node gantry type crossbeam across
Road more under bridge.When conventional gantry type crossbeam span is larger, because own wt is overweight, calculating is difficult to pass through.
Utility model content
In place of in order to overcome the above-mentioned deficiencies of the prior art, the utility model provides a kind of long overhanging crossbeam bridge structure,
It mainly includes：Steel construction longeron, prestressed concrete crossbeam and steel reinforced concrete binding site.Wherein, steel structure bridge passes through steel reinforced concrete
Binding site is connected with prestressed concrete crossbeam.Bridge is longitudinally steel construction, can mitigate the suffered deadweight of bridge so that crossbeam meter
Calculation can pass through.Steel construction has higher deformability, can adapt to crossbeam due to being indulged caused by tensioning and loss of prestress
The influence caused to displacement to longeron.Steel construction also allows for increase longitudinal external prestressing during later stage bridge maintaining.
Meanwhile, using prestressed concrete crossbeam, the rigidity of crossbeam is increased, bridge is reduced in vehicle traveling process
Vibratory sense.Concrete has preferable durability simultaneously.
The utility model is achieved by the following technical solution：
The long overhanging crossbeam bridge structure of one kind, it is characterised in that：Including steel construction longeron, prestressed concrete crossbeam and steel
Mixed binding site；Described steel construction longeron is connected by steel reinforced concrete binding site with prestressed concrete crossbeam；It is described it is pre- should
The solidifying native crossbeam of power is is made up of concrete, and inside is provided with deformed bar equipped with vertical muscle and stirrup, bottom；Described steel reinforced concrete is combined
Position includes junction steel plate and WELDING STUDS, and WELDING STUDS is welded on junction steel plate, and horizontal by WELDING STUDS and prestressed concrete
Beam is connected.
Described steel construction longeron is welded to form by box beam top plate, box beam bottom plate and box girder web, and box beam top plate is continuous
The overall structure opened, box beam top plate, box girder web and box beam bottom plate and junction steel plate are welded.
The top of the inside of described prestressed concrete crossbeam and bottom set vertical muscle, and stirrup is arranged on prestressed concrete
Native crossbeam inside circumference, stirrup is located between two WELDING STUDSs.
The beneficial effects of the utility model are：The suffered deadweight of bridge can be mitigated so that calculation of beam can pass through.Steel construction
With higher deformability, can adapt to crossbeam due to caused by tensioning and loss of prestress length travel longeron is caused
Influence.Steel construction also allows for increase longitudinal external prestressing during later stage bridge maintaining.
Meanwhile, using prestressed concrete crossbeam, the rigidity of crossbeam is increased, bridge is reduced in vehicle traveling process
Vibratory sense.Concrete has preferable durability simultaneously.
