Abstract

The invention relates to the technical field of rail transit engineering, and discloses a fabricated subway station platform and a construction method thereof.The subway station platform comprises a platform bottom plate, a pair of first prefabricated parts and a second prefabricated part, wherein the pair of first prefabricated parts is placed on the two sides of the second prefabricated part correspondingly; the bottom of each first prefabricated part is fixed to the platform bottom plate, the top edge of each first prefabricated part supports the second prefabricated part, and the first prefabricated parts and the second prefabricated part form a platform top plate; the platform bottom plate comprises a bottom flat plate and side walls, the bottom flat plate is provided with positioninggrooves, mortises are formed in the connecting positions of the side walls and the bottom flat plate, and the positioning grooves and the mortises are used for positioning and limiting the first prefabricated parts. According to the invention, each component can be accurately positioned, and large span can be realized to adapt to the condition of a column-free station.

Description

technical field [0001] The invention relates to the technical field of rail transit engineering, in particular to an assembled subway station platform and a construction method thereof. Background technique [0002] The platforms of subway stations are mostly reinforced concrete structures, which are usually constructed by pouring on site. Due to the low structure and large area of ​​the platforms, it is difficult to install and dismantle the molds, resulting in low construction efficiency and long construction period. Large resource and energy consumption, large amount of construction waste and other issues. [0003] At present, the construction of subway station platforms using prefabricated components has attracted extensive attention. For example, Chinese patent CN111501586A discloses a prefabricated platform, which utilizes the first prefabricated platform slab, the first prefabricated platform wall, the second prefabricated platform wall and the cast-in-place floor to...
