The plate transverse steel bars 74 on the upper side of the middle plate connecting structure are welded with the segment transverse steel bars 74, so that the structural strength, the shearing resistance and other stress performances of the nodes can be guaranteed.
Optionally, on the underside of the mid-plate connection, the slab transverse rebars 74 overlap the segment transverse rebars 74 to facilitate construction operations. Further, as shown in fig. 4 and 5, the corresponding end of the peripheral middle plate section 2 adopts a step structure which is formed at the bottom of the peripheral middle plate section 2 and is wide at the top and narrow at the bottom, the section transverse steel bar 74 of the peripheral middle plate section 2 extends out from the vertical connecting surface of the step structure and extends to be close to the transverse free end of the middle plate block 12, and the block transverse steel bar 74 extends to the step structure to overlap with the section transverse steel bar 74.

It will be appreciated that for the joining of two adjacent side wall panels 11, the pouring gate 82 is not required to be provided, and the concrete pouring operation can be performed from the top end of the post-pouring channel 81.
The splicing structure can ensure that adjacent plates are reliably connected, is convenient to construct, and ensures that the assembled underground station can meet the structural design requirement.
Particularly, the post-cast channel 81 is communicated with the step structure at the transverse free end of the middle plate block 12, so that post-cast concrete at the splicing node between two adjacent middle plate blocks 12 can be connected with cast-in-place concrete at the connecting node between the middle plate block 12 and the peripheral middle plate segment 2 into a whole, and the structural integrity and the stress performance of the station middle plate can be effectively improved.
