Vertical elevator holes 5 are formed in the hall floor 10, and the vertical elevator holes 5 provide a through passage for vertical elevators. The bottom end of the vertical elevator extends to the bottom surface of the platform layer, the top end of the vertical elevator penetrates out of the vertical elevator hole 5, the elevator door of the vertical elevator can be completely exposed above the vertical elevator hole 5, the vertical elevator is used for communicating the station hall layer with the platform layer, and passengers can freely enter and exit the station hall layer or the platform layer through the vertical elevator.

The scissors type staircase is tightly attached to the side face of the vertical elevator along the direction of the transverse frame beam, and the scissors type staircase is composed of two escalators which are staggered and tightly attached to each other, so that the space occupancy rate is saved. The station hall bottom plate 10 is provided with a staircase hole 16, the top end of the scissor type staircase extends to the staircase hole 16, the bottom end of the scissor type staircase extends to the bottom surface of the station layer and is used for communicating the station layer with the station hall layer, and passengers can freely enter and exit the station hall layer or the station layer through the scissor type staircase. If the station form is island formula station, passenger flow volume sharply increases when the train arrives the station simultaneously of going up and down, sets up perpendicular elevator and scissors type staircase simultaneously and can satisfy the sparse demand under this kind of situation.

As shown in fig. 1, one side of the vertical elevator penetrates the vertical frame beam 2, and the vertical frame beam 2 has a variable cross section at the vertical elevator. At the corners of the vertical elevator there are provided

corner posts

6, 7, 8 and 9 for supporting the vertical elevator car. A transverse secondary beam 12 is erected between the corner columns 6 and 7, a transverse secondary beam 13 is erected between the

corner columns
