Prestressed concrete-steel tank beam bond beam continuous beam bridge
The invention provides a prestressed concrete-steel tank beam bond beam continuous beam bridge. The prestressed concrete-steel tank beam bond beam continuous beam bridge comprises piers, a concrete-steel tank beam bond beam section and prestressed concrete box girder sections. The concrete-steel tank beam bond beam section is located in a midspan positive moment region, the prestressed concrete box girder sections are located in other positions, and steel-concrete transition sections are arranged between the prestressed concrete box girder sections and the concrete-steel tank beam bond beam section. Compared with the prior art, the prestressed concrete-steel tank beam bond beam continuous beam bridge has the following advantages that material performance is fully utilized, and engineering manufacturing cost is reduced; the spanning capacity of the bridge is improved, and the building height of a main bridge is reduced; the dead weight is effectively reduced, midspan deflection is reduced, the spanning capacity is improved, and the building height of the main bridge is reduced; the concrete-steel tank beam bond beam is connected with a bridge deck pavement layer through a concrete bridge deck, and the problem that an ordinary steel box girder bridge deck is easily damaged in the pavement process can be solved; the concrete-steel tank beam bond beam is conveniently prefabricated in a factory, the construction progress can be greatly accelerated, the bridge forming effect is good, and the bridge is especially suitable for channel crossing or overpass bridges.
