Embodiment 1

[0044] like Figure 1-4 As shown, a prefabricated module group for building or transforming a platform is composed of prefabricated module I1 and prefabricated module II2. A support edge 11 is provided on the top of the right side of the structure.

[0045] The external dimensions of the cuboid structure are length×width×height: 1200mm×1200mm×700mm, the width of the supporting edge 11 is 300mm, the length is 1200mm, and the height is 180mm; ).

[0046] The prefabricated module Ⅰ1 and prefabricated module Ⅱ2 are reinforced concrete structures, and the reinforcement adopts the first-grade steel bar with a diameter of 6mm and the third-grade steel bar with a diameter of 8mm. The reinforcement diagram is as follows image 3 , 6 shown.

[0047] like Figure 5 As shown, a prefabricated platform adopts the prefabricated module group described in Embodiment 1, and a fine stone concrete cushion 4 is laid on the base layer 10. On the cushion layer 4, the prefabricated module I1 is...

Embodiment 2

[0059] The difference from Example 1 is that the external dimensions of the cuboid structure are length×width×height: 2400mm×2400mm×1500mm, the width of the support edge 11 is 500mm, the length is 2400mm, and the height is 230mm.

Embodiment 3

[0061] A method for building a new platform differs from Embodiment 1 in that: in step ②, it is necessary to perform foundation treatment first, replace and fill with antifreeze sand, pour concrete strip foundations, and then install prefabricated modules.

Abstract

The invention aims at providing a method for constructing or reconstructing an assembled platform and a special prefabricated module group. According to the method for constructing or reconstructing the assembled platform, the efficiency of the platform constructing or reconstructing project can be comprehensively enhanced, the platform constructing or reconstructing project quality can be comprehensively improved, the construction is simple and flexible, manpower and material resources are saved, the influences on running and transportation are small, the method is safe and time-saving, and the potential safety hazard in the later period is reduced. The method for constructing or reconstructing the assembled platform comprises the specific construction steps of 1, preparing a prefabricated module group with a reinforced concrete structure; 2, mounting the prefabricated module group to a designated position by using a hoisting appliance; treating a foundation of a new platform and filling anti-freezing sand first, and then mounting prefabricated modules after pouring a concrete strip-shaped foundation; 3, binding reinforcing meshes on the prefabricated modules and pouring a concrete cushion; 4, comprehensively laying pipelines; and 5, after the concrete cushion reaches the strength, continuing to lay a slope making layer, a leveling layer and a sand cushion; and laying a platform cap-beam, a safety line, blind bricks and pavement bricks to finish the construction.

Description

technical field [0001] The invention relates to the construction or reconstruction of a railway station platform, and in particular provides a method for building or reconstruction of an assembled platform and a special prefabricated module group. Background technique [0002] The high platform of the railway station is designed to cooperate with some trains such as direct trains, EMUs, and high-speed trains. Its basic starting point is to realize barrier-free boarding and disembarking of trains, save time in and out, facilitate passengers to enter and exit trains, and prevent individual passengers from crossing the railway line Play a certain security role. Its height is basically the same as the floor of the train compartment door. Therefore, no matter what type of car is parked on the high platform, after opening the door, there is no need to open the flap. Passengers can directly step into the compartment on the platform, which saves effort and is convenient. save time....
