Abstract

The invention discloses an assembly type steel and concrete arch bridge T beam plate. The assembly type steel and concrete arch bridge T beam plate comprises a bottom plate, a top plate and wave-shaped steel webs arranged between the bottom plate and the top plate. The bottom plate is in an arch shape along a bridge in the axial direction, connecting vertical plates are arranged on the arch-shaped bottom plate, the lower end faces of the connecting vertical plates are welded to the arch-shaped bottom plate, the upper end faces of the connecting vertical plates are planes, and longitudinal connecting plates with threaded holes are welded to the upper end faces of the connecting vertical plates. Longitudinal steel plates are welded to the upper end faces and the lower end faces of the wave-shaped steel webs respectively, and the upper end faces and the lower end faces of the wave-shaped steel webs are connected with the longitudinal connecting plates and the top plate through connecting parts. Split manufacturing and transporting are adopted, it is only needed to perform connecting and fastening through bolts or screws, the assembly type steel and concrete arch bridge T beam plate is simple in structure, easy to construct, short in construction period and reliable in quality because the T beam plate is produced by the adoption of factory standardization; because the arch-shaped structure or the parabolic-arch-shaped structure is adopted for the bottom plate, resistance to load deflection of the bridge type can be substantially improved, and compared with a slab bridge, pre-stress can be omitted under the same span.

Description

technical field [0001] The invention belongs to the field of bridge collapse structure design, and in particular relates to an assembled steel-concrete arch bridge T-beam slab. Background technique [0002] At present, there are steel-concrete beams, reinforced concrete beams, and prefabricated steel-concrete box girders for bridges and bridge decks used for roads or railways. For steel-concrete beams, the cost of pure steel beams is high and the investment is large; for reinforced concrete beams, the "T" beams are heavy and difficult to prefabricate, requiring on-site fabrication and a long construction period. The prefabricated steel-concrete box girder has a large volume after being prefabricated in the factory, which is not conducive to transportation, and the steel-concrete box girder in the prior art is a planar structure, and its anti-disturbance performance is poor. Contents of the invention [0003] The technical problem to be solved by the present invention is t...
