Description

Technical Field

[0001] This utility model relates to the technical field of elevated stations, and in particular to a fully precast concrete modular elevated station in the middle of the road. Background Technology

[0002] With the deepening of green building concepts and the maturity of prefabricated building technologies, elevated railway stations, as an important component of urban transportation infrastructure, are undergoing a transformation from traditional cast-in-place construction to green prefabricated construction. This transformation is driven by the deep integration of standardized design, factory production, and prefabricated construction.

[0003] The current mainstream construction method for elevated railway stations mainly uses cast-in-place concrete for the main structure, without modularization; it combines secondary decoration of the ground, walls, and roof with the installation of steel structures for the roof canopy, and the overall construction method is relatively mature. However, for elevated railway stations in the middle of the road constructed using traditional methods, not only is the road occupancy time long during construction, but after completion and operation, there are still safety, durability, and aesthetic problems such as aging, corrosion, and falling of the exterior surface. Summary of the Invention

[0004] The purpose of this utility model is to address the shortcomings of the existing technology by providing a fully precast concrete modular elevated station in the middle of the road. This station is constructed using precast concrete modules, which reduces the impact on road traffic, shortens the construction period, and reduces environmental pollution. At the same time, during the construction and operation period, the elevated station can achieve long-term stable operation by virtue of the safety, durability, and aesthetic features of the precast concrete modules themselves.

[0005] The objective of this utility model is achieved through the following technical solution:

[0006] A precast concrete modular elevated station is disclosed, comprising, from bottom to top, an elevated level, a concourse level, a platform mezzanine, and a platform level. The elevated level has piers; the concourse level has cantilevered cap beams, structural beams, floor slabs, and structural columns; the platform mezzanine has mezzanine cap beams, structural beams, floor slabs, structural columns, and track beams; and the platform level has structural beams, floor slabs, roof canopy columns, longitudinal beams, and a large roof canopy slab. The lower ends of the elevated level piers are connected to the station platform below ground level, and the upper ends are supported by the middle of the cantilevered cap beams of the concourse level. The structural beams of the concourse level are installed on the cantilevered cap beams. The station hall floor slab is located on the station hall structural beam. The lower end of the station hall structural column is connected to the station hall cantilever cap beam, and the upper end is supported by the platform mezzanine cap beam. The platform mezzanine structural beam is installed on the platform mezzanine cap beam. The platform mezzanine floor slab is located on the platform mezzanine structural beam. The platform mezzanine track is installed on the platform mezzanine structural beam. The lower end of the platform mezzanine structural column is connected to the platform mezzanine structural beam, and the upper end is supported by the platform structural beam. The platform floor slab is located on the platform structural beam. Roof canopy columns are installed on both sides of the platform structural beam. The roof canopy columns on the same side are connected by roof canopy longitudinal beams. The roof canopy large cover plate is installed on the roof canopy longitudinal beams.

[0007] The station hall structural beam includes a central longitudinal beam, side longitudinal beams, and a transverse beam. The central longitudinal beam and the side longitudinal beams are connected by the transverse beam.

[0008] The station hall structural columns are divided into central structural columns and side structural columns. The central structural columns support the middle part of the platform mezzanine cap beam, and the side structural columns support the sides of the platform mezzanine cap beam.

[0009] The platform mezzanine structure beam includes a central longitudinal beam, side longitudinal beams, and a transverse beam. The central longitudinal beam, the side longitudinal beam, and the central longitudinal beam are all connected by the transverse beam.

[0010] The platform layer structural beams are arranged opposite each other in the transverse direction, and both sides of the platform layer structural beams are supported by the platform mezzanine structural columns.

[0011] The platform level structural beam includes a central longitudinal beam, side longitudinal beams, and a transverse beam. The central longitudinal beam and the side longitudinal beams are both supported by the platform mezzanine structural columns. The central longitudinal beam and the side longitudinal beams are connected by the transverse beams.

[0012] Both sides of the concourse level and the platform mezzanine are equipped with integrated structural insulation and decorative wall panels.

[0013] The advantages of this utility model are:

[0014] 1. It can realize the modularization and prefabrication of all civil engineering structures of elevated stations except for the station piers, and carry out prefabricated construction, realizing standardized design, factory production and prefabricated construction, which is a manifestation of the transformation and upgrading of construction methods in the construction industry;

[0015] 2. During the station construction phase, compared with the traditional cast-in-place concrete construction method, the construction period is shorter, the social impact is smaller, and it is green, low-carbon, and environmentally friendly.

[0016] 3. During the station operation phase, compared with traditional elevated stations which suffer from safety, durability, and aesthetic problems due to secondary renovations, steel structure aging, corrosion, and potential collapses caused by their age, modular concrete elevated stations can effectively solve the above-mentioned engineering pain points by utilizing the environmentally friendly, energy-saving, stable quality, and strong natural aesthetic characteristics of concrete components.
