Abstract

The invention discloses a fabricated subway station platform. The fabricated subway station platform comprises side joists, a middle joist, side platform plates and a middle platform plate. The prefabricated edge joists and the prefabricated middle joist are fixed to the ground through expansion bolts, and the side platform plates and the middle platform plate are fixed to the corresponding side joists or the corresponding middle joist through field drilling and bar planting. The fabricated subway station platform has the following advantages: the structure is simple, the weight of a single piece is light, and transportation and installation are convenient; structural functions are complete, other professional work amount is reduced, and the construction speed can be increased; and a plateand beam fixing device is free of maintenance, durability is improved, all components are modularized, length and width adjustment is facilitated, factory production is facilitated, and the plate andbeam fixing device has high adaptability to different environments.

Description

technical field [0001] The invention belongs to the technical field of secondary structure of subway station building engineering, and in particular relates to an assembled subway station platform and a construction method thereof. Background technique [0002] The platform of the subway station is the main platform for passengers to get on and off the train. In order to ensure the safety of passengers, screen doors need to be installed on the platform. At the same time, when the train enters the station, there is a voltage difference between the screen door and the ground, and an insulating layer is required on the platform for protection. The platform is a reinforced concrete structure, which is traditionally constructed by pouring in situ. Due to the low height and large area of ​​the platform structure, it is difficult to install and dismantle the mold. The construction time is long, the cost is high, and the quality is difficult to control. [0003] In recent years, th...
