Beam-column joint structure of elevated station and interval bridge

Abstract

The invention provides a beam-column joint structure of an elevated station and an interval bridge. The beam-column joint structure comprises elevated station side span beams arranged at the two endsof the elevated station and the interval bridge in butt joint with the elevated station side span beams. The elevated station side span beam and the interval bridge are jointly supported on the station and bridge shared pier stud through sliding supporting pieces, and a beam end deformation joint is arranged between the elevated station side span beam and the interval bridge. The elevated stationside pier and interval bridge pier column are combined into one pier column; the two structural systems of the elevated station and the intervalbridge are connected with the station bridge sharedpiercolumnthrough the sliding supporting pieces; the deformation of the two structural systems is not influenced by each other; according to the structural form, double columns are prevented from being arranged at a deformation joint between the elevated station and the interval bridge, the overall shape of the elevated station and the interval bridge is greatly improved, the elevated station and theinterval bridge are connected more naturally, investment is saved after pier columns are combined, construction is easier and more convenient, and the construction period is further shortened.

Description

technical field [0001] The invention belongs to the technical field of rail transit engineering, and in particular relates to a beam-column node structure of an elevated station and an interval bridge, which is applied to the structural design of an elevated station of frame structure type in rail transit engineering. Background technique [0002] More and more urban rail transit and urban rail transit adopt elevated lines, and are generally laid in the middle of urban roads. [0003] At present, when the elevated station structure is connected with the section bridge structure, since the station structure generally adopts the frame structure system commonly used in civil buildings, the load on the beam-slab structure is transmitted to the foundation through the frame columns; the bridge structure is usually a simply supported beam or The continuous beam is supported on the bridge pier through the bridge support, so that the elevated station structure and the bridge structur...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to overcome the problem that the existing elevated station and the bridge are connected by double columns, forming a seam from top to bottom, and the cross-sectional size of the two columns is very large, which affects the urban landscape and the overall modeling effect of the elevated station.
