As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

Referring to fig. 1 to 3, a platform installation structure for an additional station in an existing elevated line area includes a plurality of prefabricated panels, which are tiled; the prefabricated slab is supported on the supporting frame; and the first connecting piece 310 is arranged between the prefabricated slab and the support frame, and the first connecting piece 310 is used for connecting the prefabricated slab and the support frame into a whole.

This a platform mounting structure that is used for existing overhead line district to add station only needs the construction support frame can, and the construction of support frame does not influence the rail line district of having operated at the downside of overhead line, and after the support frame construction was accomplished, hoist and mount prefabricated plate night and carry out laying of station platen, compares the mode of pouring the construction, can not influence the normal operation in rail line district, and not only the efficiency of construction is high, and the construction risk is little moreover.

Because the train needs to guarantee normal operation in the operating time quantum, if adopt the platform of cast in situ concrete mode construction add, then must influence normal train operation, this is that the actual condition does not allow.

In the platform installation structure for additionally arranging the station in the existing elevated line area, the platform plate adopts the structure of the precast slab, and the support frame at the lower part of the precast slab can be constructed in a cast-in-place way, since the supporting frame is arranged below the surface of the precast slab, the height of the precast slab is equivalent to that of the rail-bound area, that is, for an overhead line, the support frames are positioned at the two sides of the rail running area and at the lower part of the rail running area, so that the normal operation of the train in the rail running area is not influenced by the construction of cast-in-place concrete in the area, after the construction of the support frame is finished, when the train is in a non-operation time period (such as the subway stops operating at night), the precast slabs are laid on the support frame, due to the fact that the prefabricated slab mode is adopted, compared with a station bedplate adopting a pouring construction mode, pouring construction is not needed, and the problem that construction cannot be completed within one train stop operation time due to long pouring construction time is solved.

The support frame is used for supporting the precast slab; the first connecting member 310 is used for connecting the supporting frame and the prefabricated panel into a whole, so that the connection firmness of the supporting frame, the prefabricated panel and the prefabricated panel is enhanced.

Further, the first connecting member 310 may cast concrete in situ to connect the supporting bracket and the prefabricated panel as one body.

Of course, it should be understood by those skilled in the art that the prefabricated panels and the supporting frames may be provided with corresponding anchor bars, so that the prefabricated panels and the supporting frames are more firmly connected together by cast-in-place concrete (the first connecting member 310), and the details are not repeated.

Considering the convenience of hoisting during subsequent construction, the size of the prefabricated plate is not suitable to be too large, such as a plate with 4.64m by 5.20m, the thickness is 200mm, and the weight is 12 t.

Referring to fig. 1, the prefabricated slab includes a first slab 110 and a second slab 120, the first slab 110 and the second slab 120 are arranged at intervals, the supporting frame includes a first supporting beam 210, the first supporting beam 210 is provided with a plurality of supporting beams and arranged at intervals, a first end 111 of the first slab 110 is erected on one side of the first supporting beam 210, a second end 121 of the second slab 120 is erected on the other side of the first supporting beam 210, so that a first groove is formed at the top end of the first end 111, the top end 121 and the top end of the first supporting beam 210, and a first connecting member 310 is arranged in the first groove and connects the first slab 110, the second slab 120 and the first supporting beam 210 into a whole.
