At present, the railway passenger station elevated station generally adopts cast-in-place concrete, and has the following defects: 1. the cast-in-place concrete has long curing time and is greatly influenced by weather, so that the total construction period is long, railway passenger and cargo transportation is influenced, and indirect loss is large; 2. the steel bars are bound on site, concrete is poured, a large number of templates are needed, the workload is large, most of work is completed by construction site workers, the labor intensity is high, the construction site is disordered, a large amount of construction waste is generated, and the influence on the surrounding environment is large; 3. the elevated station has a relatively high drop distance from the ground, and the support to be erected is relatively high, which results in relatively high support cost.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a railway passenger station assembled elevated platform for solving the above-mentioned problem.
The utility model discloses a following technical scheme realizes above-mentioned purpose: an assembled elevated station platform of a railway passenger station comprises elevated columns, steel beams, a precast concrete station platform plate, a fine aggregate concrete post-cast plate strip and a fine aggregate concrete leveling layer; the fine aggregate concrete post-cast slab band is located above the steel beam, the precast concrete platform plate is located on two sides of the fine aggregate concrete post-cast slab band, the fine aggregate concrete leveling layer is located above the precast concrete platform plate and the fine aggregate concrete post-cast slab band, and the fine aggregate concrete post-cast slab band and the fine aggregate concrete leveling layer are integrally cast.
As a further aspect of the present invention: the fine aggregate concrete post-cast plate is provided with a closed beam structure on the plane.
As a further aspect of the present invention: and longitudinal steel bars matched with the precast concrete platform plate extend out of the plate end, continue to penetrate into the fine aggregate concrete post-cast strip in the node area and are anchored in the fine aggregate concrete post-cast strip in the node area.
A construction method of an assembled elevated platform of a railway passenger station comprises the following steps:
firstly, preparing an elevated column, a steel beam and a precast concrete station bedplate;
step two, installing the elevated column, the steel beam and the precast concrete platform plate at an appointed position by adopting hoisting equipment;
step three, integrally pouring the fine stone concrete post-cast slab band plate and the fine stone concrete leveling layer;
and step four, paving a decorative layer after the fine aggregate concrete post-cast plate belt plate and the fine aggregate concrete leveling layer reach the strength, and finishing construction.
The utility model has the advantages that: 1. the main structure realizes basic complete assembly, a large amount of steel bar binding, concrete pouring and template mounting and dismounting work can be omitted on a construction site, the working time of the construction site is effectively shortened, the construction is simple and flexible, and the construction efficiency and the construction quality are comprehensively improved;
2. the component has small mass, does not need to prepare special equipment, is more flexible in production site and is convenient to hoist and transport;
3. the fine aggregate concrete post-cast slab band and the fine aggregate concrete leveling layer are integrally cast to form the rigid floor slab, so that the seismic performance of the structure is guaranteed.

Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1 to 3, an assembled elevated platform for railway passenger stations comprises elevated columns 1, steel beams 2, a precast concrete station board 3, a fine aggregate concrete post-cast slab band 4 and a fine aggregate concrete leveling layer 5; the fine aggregate concrete post-cast slab band 4 is located above the steel beam 2, the precast concrete station board 3 is located on two sides of the fine aggregate concrete post-cast slab band 4, the fine aggregate concrete leveling layer 5 is located above the precast concrete station board 3 and the fine aggregate concrete post-cast slab band 4, and the fine aggregate concrete post-cast slab band 4 and the fine aggregate concrete leveling layer 5 are integrally cast.
Further, in the embodiment of the present invention, the fine aggregate concrete post-cast slab band 4 forms a closed beam structure on a plane.
Further, in the embodiment of the utility model provides an in, the longitudinal reinforcement 6 that precast concrete station platen 3 was furnished with stretches out the board end to continue to go deep into the regional pea gravel concret post-cast strip 4 of node, anchor in the regional pea gravel concret post-cast strip 4 of node.
A construction method of an assembled elevated platform of a railway passenger station comprises the following steps:
firstly, preparing an elevated column 1, a steel beam 2 and a precast concrete platform plate 3;
step two, installing the elevated column 1, the steel beam 2 and the precast concrete platform plate 3 at the designated positions by adopting hoisting equipment;
step three, integrally pouring the fine stone concrete post-cast slab band plate 4 and the fine stone concrete leveling layer 5;
