Subway station transfer stair wall reinforcing structure

Abstract

The invention provides a subway station transfer stair wall reinforcing structure. The subway station transfer stair wall reinforcing structure comprises a bottom plate, a frame beam, a stair plate, astair platform, a wall and wall reinforcing steel bars. The bottom plate is a main structural part of a station. The wall is arranged on the stair plate above a rail-mounted area. The wall is tightlyattached to the outer edges of the two sides of the stair plate. The upper portion of the outer side of the wall is tightly attached to the bottom plate. The stair platform is arranged above a middleplatform stair plate. The frame beam comprises frame cross beams and frame longitudinal beams. The frame cross beams and the frame longitudinal beams are arranged in a criss-cross mode. The wall reinforcing steel bars comprise wall internal steel bars and anchoring steel bars. According to the subway station transfer stair wall reinforcing structure, the transfer stair wall and the peripheral structure of the transfer stair wall are anchored, so that the rigidity, the shear resistance and the bending resistance of a subway transfer stair are enhanced, and meanwhile the capacity of the transfer stair rail-mounted area wall for resisting long-term dynamic load effects such as train vibration and piston wind is improved.

Description

technical field [0001] The invention belongs to the technical field of subway station transfer stairs, and in particular relates to a wall reinforcement structure for subway station transfer stairs. Background technique [0002] With the development of my country's rail transit projects, subway lines are gradually forming a network, and the number of transfer stations is increasing. For multi-line transfer stations, subway lines are generally opened in stages, and transfer nodes will be reserved for lines that are opened first. On the one hand, the decoration sequence of the platform layer of the later-opened line is later than that of the first-opened line. When constructing this part of the interchange staircase wall and keel, there will be safety hazards to the track area of ​​the line that has already been in operation. On the other hand, the transfer stairs at the station platform of the later opened line are located directly above the track area of ​​the opened line. ...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a wall reinforcement structure for transfer stairs in subway stations, so as to at least solve the problems of poor overall performance of the side walls of transfer stairs in subway stations, poor resistance to piston wind pressure, and the risk of collapse
