Railway passenger station assembly type elevated platform and construction method thereof

Abstract

The invention discloses a railway passenger station assembly type elevated platform and a construction method thereof. The railway passenger station assembly type elevated platform comprises an elevated column, a steel beam, a prefabricated concrete platform plate, a fine aggregate concrete post-cast plate strip and a fine aggregate concrete leveling layer. The basic full assembly of a main body structure is achieved, a large amount of steel bar binding, concrete pouring and formwork mounting and dismounting work can be omitted on a construction site, the working time of the construction siteis effectively shortened, construction is simple and flexible, and the construction efficiency and quality are comprehensively improved; the components are small in mass, special equipment does not need to be prepared, component production places are more flexible, and hoisting and transportation are facilitated; and the fine aggregate concrete post-cast plate strip and the fine aggregate concreteleveling layer are integrally poured to form a rigid floor slab, so the anti-seismic property of the structure is guaranteed.

Description

technical field [0001] The invention relates to an elevated platform, in particular to an assembled elevated platform of a railway passenger station and a construction method, belonging to the technical field of assembled concrete structures in structural engineering. Background technique [0002] With the continuous advancement of my country's modernization process, high-speed railways occupy a dominant position in the ground transportation of intercity trunk lines in my country. Railway passenger stations have developed rapidly as a combination of transportation and urban space, and elevated platforms are an important part of railway passenger stations. Convenient for passengers Entering and exiting the passenger car, preventing individual passengers from crossing the railway line plays a certain role in safety, can provide passengers with convenient travel conditions and humanized services, and reduces the impact on ground traffic and navigable rivers passing through its tw...

Problems solved by technology

[0003] At present, cast-in-place concrete is generally used for the elevated platform of railway passenger stations, which has the following disadvantages: 1. The curing time of cast-in-place concrete is long, and it is greatly affected by the climate, resulting in a long total construction period, affecting railway passenger and cargo transportation, and causing large indirect losses; 2. 1. On-site binding of steel bars and pouring of concrete requires a large amount of formwork, and the workload is relatively large. Most of the work is done by workers on the construction site. Not only is the labor intensity high, the construction site is chaotic, but also a large amount of construction waste is generated, which has a great impact on the surrounding environment; 3. The elevated platform has a relatively high drop distance from the ground, and the support to be erected is relatively high, resulting in a large support cost
