Track traffic overhead station

Abstract

The invention discloses a track traffic overhead station. The track traffic overhead station comprises a plurality of single-column steel-concrete combined frame structures, and each single-column steel-concrete combined frame structure comprises a pier column, a first steel-concrete combined beam, a second steel-concrete combined beam, platform structures, track beams and a roof canopy; the first steel-concrete combined beams are mounted at the tops of the pier columns through first combined beam column nodes; the second steel-concrete combined beams are mounted at the tops of a middle column and side columns of a station hall layer through second combined beam column nodes; the roof canopies are mounted at the tops of supporting columns of the two ends of the second steel-concrete combined beams; and the first steel-concrete combined beams and the second steel-concrete combined beams are each a square steel pipe combined beam with a containing cavity, and the bottoms of the containing cavities and the connecting positions of the containing cavities and the first combined beam column nodes or the second combined beam column nodes are poured with concrete. By adoption of the track traffic overhead station, the self weights of structural components can be reduced, structural ductility and seismic performance are improved, and the construction period is shortened.

Description

technical field [0001] The invention relates to rail transit technology, in particular to a rail transit elevated station. Background technique [0002] At present, the elevated stations (side platforms and island platform stations) of domestic rail transit projects adopt a relatively high proportion of single-column structures, and all of them adopt cast-in-place reinforced concrete structures. The advantage of this structure is that the maintenance workload during operation is relatively small, and the engineering cost is relatively low. [0003] However, the above-mentioned rail transit elevated station using traditional concrete single column structure in the prior art also has the following disadvantages: [0004] 1. The traditional concrete single-column structure is self-heavy, the component size is large, the structural volume is large, and the overall lateral force resistance system of the structure has only one single column, which will bear a large axial force an...

AI Technical Summary

Problems solved by technology

During a large earthquake, the plastic hinge formed by a single reinforced concrete column has poor ductility, which cannot consume the energy of the structure during vibration, and is prone to irreparable damage. Therefore, the seismic performance of the structure under earthquake is poor.

[0005] 2. The traditional concrete single-column structure adopts the method of on-site pouring, and the construction is complicated. Generally, the following procedures are required: erecting a full hall of scaffolding to pour beam-slab components; supporting formwork to pour beam-column components; binding steel bars, etc.

All the above processes need to be completed on site, resulting in disadvantages such as long construction period, long road occupation period, and difficulty in pouring concrete.

[0006] 3. Due to the large size of the components of the traditional concrete single-column structure, it has a negative impact on the urban landscape

At the same time, the concrete structure will have a great impact and pollution on the surrounding environment during the construction process.

[0007] 4. The traditional concrete single-column structure has a large self-weight load, a large amount of reinforcement for beam-column components, a small clear distance between steel bars, and a large amount of engineering work for binding steel bars, which makes concrete pouring difficult and difficult to control the construction quality
