Embodiment Construction

[0029] The present invention will be described in further detail below through specific embodiments in conjunction with the accompanying drawings.

[0030] Considering the complex installation method and difficult maintenance of the existing intercity railway sidewalk structure, this embodiment provides a simply supported T-beam sidewalk composite structure and a composite method for the intercity railway.

[0031] The composite structure includes: embedded parts, steel beams and cast-in-place concrete slabs; among them, the embedded parts are placed in the prefabricated protective wall of the intercity railway beam body, and the root of the steel beam is fixedly connected with the embedded parts; the upper part of the steel beam The surface is on the same plane as the upper surface of the prefabricated protective wall; the upper surface of the prefabricated protective wall and the upper surface of the steel beam are all cast-in-place concrete to form the cast-in-place protecti...

Abstract

The invention relates to an interurban railway simple support T-beam sidewalk combined structure and a combining method. The interurban railway simple support T-beam sidewalk combined structure comprises a pre-embedded piece, a steel cross beam and a cast-in-place concrete plate. The pre-embedded piece is arranged in a prefabricated protection wall of an interurban railway beam, the root of the steel cross beam is fixedly connected with the pre-embedded piece, and the upper surface of the steel cross beam and the upper surface of the prefabricated protection wall are arranged on the same plane. Concrete is poured to the upper surface of the prefabricated protection wall and the upper surface of the steel cross beam to form a cast-in-place concrete wall and a cast-in-place concrete plate which are of an integrated structure. According to the structure, overall bearing capacity is improved, the structural integrity is good, and a steel component and welding materials are made of weathering resistant steel, so that the workload of later maintenance is reduced.

Description

technical field [0001] The invention relates to railway technology, in particular to a combined structure and combined method of simply supported T-beam sidewalks for intercity railways. Background technique [0002] A large part of my country's railway bridges adopt simply supported T-beams, and sidewalks are set on both sides of the bridge deck for railway maintenance personnel to walk. The sidewalk is in the form of steel brackets, which are welded or spliced ​​with angle steel, fixed to the bridge deck ballast wall by pre-embedded U-shaped bolts or pre-embedded T-shaped steel, and reinforced concrete sidewalk steps are laid on the brackets. The construction process is complicated, and the later maintenance and repair workload is heavy. Contents of the invention [0003] The object of the present invention is to provide a simply supported T-beam sidewalk composite structure and a composite method for an intercity railway, so as to solve the problems of simplifying cons...
