Beam spanning multilayer deck

Abstract

The invention relates to a beam spanning a multilayer deck, which has the technical scheme that a web spans the multilayer deck; an upper flange, a lower flange, the web and a panel are integrally connected to work together to be used as a common beam in an interior passageway of the beam, and the interior passageway of the beam is used as a motor vehicle passageway, a trolleybus passageway, a track traffic passageway, a magnetic suspension passageway, a pipeline passageway and a pedestrian passageway. The invention has the technical effect that the beam can adapt to a large span when being used for a beam bridge and has economical efficiency; the trafficability can be improved when the beam is used for stayed-cable bridges or suspension bridges; and the beam has small solid thickness, and is favorable for the arrangement of the multilayer deck, utilization of land and space resources and intensive utilization of traffic passageway resources. The beam of the invention is suitable to be used as a simply-supported beam, a continuous beam, a rigid frame bridge main beam, a stayed-cable bridge main beam and a suspension bridge main beam of an elevated track, an elevated high-speed railway, an elevated magnetic suspension, an elevated trolleybus, an elevated road, a comprehensive elevated passageway, a multilayer river-crossing large bridge, a multilayer ocean-crossing large bridge and the like.

Description

Technical field: [0001] The invention belongs to the field of bridge engineering, and in particular relates to a beam used for bridge structures, a web spanning multi-layer bridge decks and integrally connected with upper flanges and lower flanges to work together as a common multi-layer bridge deck. Background technique: [0002] At present, there are various forms of bridge structures, which can generally be divided into arch bridge structures, beam bridge structures (including rigid frame bridge structures), cable-stayed bridge structures, suspension bridge structures, and truss bridge structures. Among them, the girder bridge structures with a span of more than 30m mainly include prestressed reinforced concrete simply supported T-beams and prestressed reinforced concrete continuous box girders. [0003] The prestressed reinforced concrete simply supported T-beam is composed of upper flange and web. The T-beam bridge is used for a single layer. Multiple T-beams are connec...

Problems solved by technology

[0014] The technical problem to be solved by the present invention is to provide a beam spanning multi-layer bridge decks, which solves the problem that the beam bridge structure has been difficult to adapt to large spans, and the high beam height is not conducive to the setting of multi-layer bridge decks, and is not conducive to making full use of land and space. resource problem
