Problems solved by technology

Most of the existing single-column stations are reinforced concrete structures, and the large cantilever beams are prestressed. Under the action of strong earthquakes in the octave area, the ductility of reinforced concrete beams and columns is poor, and irreparable failures are likely to occur. destroy

Abstract

The invention relates to the technical field of railway station construction, in particular to an elevated single-column station. In the present invention, by adding H-shaped steel at the bottom of the concrete-filled steel pipe column and reliably connecting with the bottom of the concrete-filled steel pipe column, the embedding depth of the concrete-filled steel pipe column is reduced, and the internal force of the column bottom is effectively transmitted to the bearing platform through the H-shaped steel "wedge". The platform concrete is transferred to the pile foundation. The single-column piers of the elevated single-column station usually have a large cross-section. Reducing the structural embedment depth of the concrete-filled steel tube column can greatly reduce the excavation depth of the foundation, reduce the engineering cost of the foundation part, and effectively utilize the fast construction speed and cycle time of the steel tube-concrete composite structure. It is short and has little impact on municipal roads, which is in line with the national industrial policy.

Description

technical field [0001] The invention relates to the technical field of railway station construction, in particular to an elevated single-column station. Background technique [0002] As a new type of structural system, the elevated single-pillar station is rarely used in Badu District. Most of the existing single-column stations are reinforced concrete structures, and the large cantilever beams are prestressed. Under the action of strong earthquakes in the octave area, the ductility of reinforced concrete beams and columns is poor, and irreparable failures are likely to occur. destroy. Elevated single-column station Because the section of the single-column pier of the elevated single-column station is generally larger, especially in the cross-bridge direction, this will lead to a high height of the cap of the elevated single-column station. Contents of the invention [0003] The object of the present invention is to provide an elevated single-column station to improve th...
