Description
Technical Field
The utility model relates to a bridge construction technical field especially relates to a simply supported beam steel sheet bridge floor continuous structure.
Background
The medium and small bridges play an important role in bridge construction in China. In the conventional medium and small bridges, the statically determinate simply supported bridge has the characteristics of clear stress, simple structure, convenient construction and easy maintenance. But need set up the expansion joint device in porous simple beam bridge, under the more condition of span number, the expansion joint device that uses also can increase, has not only influenced the ride comfort of driving, has also increased the bridge cost simultaneously.
Compared with the solution of multi-span simply supported beam and expansion joint, the prestressed continuous beam bridge has the advantages of large rigidity, small deformation, strong shock resistance, seamless structure and smooth driving, and the expansion joint only needs to be arranged at the bridge abutment, and the like, so that the prestressed continuous beam bridge is widely applied. But compare in traditional simple beam, continuous beam bridge work progress is more loaded down with trivial details relatively, and the cost is higher and take a lot of work and time. Meanwhile, because the continuous beam is of a statically indeterminate structure, the secondary internal force generated by tension prestress, temperature effect, shrinkage and creep of concrete and the like needs to be considered, and the stress is more complex.
SUMMERY OF THE UTILITY MODEL
In order to overcome the defects existing in the prior art, the utility model provides a simply supported beam steel plate bridge floor continuous structure.
The utility model discloses the technical problem that will solve adopts following technical scheme to realize:
the utility model provides a simply supported beam steel sheet bridge floor continuous structure, this structure applies to adjacent two and strides the continuous department of simply supported beam decking, includes:
the rooting steel bar is positioned in the end part of the bridge deck, and the top of the rooting steel bar is connected with a first steel plate; the first steel plate is flush with the top surface of the bridge deck;
a second steel plate;
wherein, the second steel sheet passes through the first steel sheet of welding mode connection adjacent two strides, lays asphalt concrete layer on second steel sheet and the decking.
Further technology:
preferably, the two ends of the rooting steel bar are in the same direction and are positioned on the same horizontal plane.
Preferably, the rooting steel bars and the first steel plate are connected through welding and are embedded in the bridge deck in advance.
Preferably, the bridge deck is internally provided with transverse steel bars, and the rooting steel bars are connected with the transverse steel bars in the bridge deck.
