Fastening method of T-shaped beam bridge

Abstract

The invention relates to a fastening method of a T-shaped beam bridge. The T- shaped beam bridge comprises a plurality of T-shaped beams with the sections being T-shaped; the T-shaped beams comprise a wing plate positioned in a horizontal part and a ventral shield positioned in a vertical part; the fastening method comprises the following steps: reinforcing steel bars are embedded between the ventral shields of the adjacent T- shaped beams and concrete is poured thereinto so that the at least one concrete cross beam along the T-shaped beam span direction is arranged between the ventral shields of the adjacent T- shaped beams. The fastening method of the T-shaped beam bridge solves the problems existing in the prior art fastening the hinge T- shaped beam that the articulation connection is lacking; the jointing position of the articulation seam is easy to weaken and even fails; the whole rigidity of the bridge is not high.

Description

technical field

[0001] The invention relates to a reinforcing method of a bridge, in particular to a reinforcing method of a hinged T-beam bridge. Background technique

[0002] At present, among the existing T-beam bridges built in my country, most of the transverse connections between T-beams are hinge connections, and the hinge connections are realized by setting hinged steel plates between adjacent T-beams ( See figure 1 ), when using the hinge connection, because it only transmits shear force, the bending moment is mainly borne by the cast-in-place bridge deck when the vehicle load acts on the hinge joint, while a large number of active hinged T-beam bridges in China have cast-in-place bridge decks The thickness of the T-beam is small, so the bridge deck at the hinge joint is prone to long longitudinal cracks, which not only affects the traffic, but also weakens or even fails the transverse connection between the T-beams, so that the load is mainly caused by the T-beam w...
