It is a column-free structure of the station hall, which makes the space visually open and visually transparent without increasing the project cost, and is also conducive to passenger flow guidance; a number of frame columns are arranged between the middle plate 9 and the bottom plate 8 or between two layers of middle plates 9. In addition to the frame columns arranged around the platform layer, there are also frame columns arranged in the middle of the platform layer to support the middle plate 9 and the structure above the middle plate 9; preferably, the frame columns arranged around the platform layer and the frame columns arranged around the station hall layer are located on the same straight line.
[0028] A plurality of top longitudinal beams 2 are provided at the bottom of the top plate 1, which are used to support the top plate 1 and enhance the stability of the station hall layer; a plurality of middle longitudinal beams 6 are provided at the bottom of the middle plate 9, which are used to support the middle plate 9 and enhance the stability of the platform layer and the station hall layer.
[0029] Preferably, in this embodiment, a cross beam 5 is arranged at the middle top plate, and the cross beam 5 includes a transverse beam and a longitudinal beam perpendicular to each other, and the ends of the transverse beam and the longitudinal beam are placed on the side wall 3. Furthermore, the longitudinal and transverse spans of the transverse beam are determined according to the size of the station hall to meet the force requirements of the top plate.
[0030] Furthermore, the transverse and longitudinal spans of the raised middle top plate are 3m to 4m, preferably 3.5m, so that the raised middle top plate can be arranged within a reasonable stress range.
[0031] The transverse and longitudinal beams arranged at vertical intervals form a mesh support structure at the bottom of the middle top plate, which is used to provide stable support for the top plate without columns and with an elevated setting, thereby ensuring the stability of the structure.
[0032] Furthermore, a plurality of bottom longitudinal beams 7 are provided on the top of the bottom plate 8 to enhance the strength of the bottom plate.
