Lattice column penetrating structure floor node structure for underground station construction

A lattice column penetrating structure floor slab node structure for underground station construction is used for effectively avoiding the problem that floor slab reinforcing steel bars are discontinuous due to lattice columns in underground station construction and reducing the tedious procedure of digging out the floor slab reinforcing steel bars in the later period. The latticed column is formed by welding equilateral angle steel components and steel batten plates, the equilateral angle steel components are located at the four corners of the rectangular section to serve as limb pieces, and the steel batten plates are connected with the two adjacent equilateral angle steel components in a welded mode. At the intersection node position of the latticed column and the station structural floor slab, the structural plate reinforcing steel bars perpendicularly intersected with the steel batten plate penetrate through reinforcing steel bar holes in the plate face of the steel batten plate, and the adjacent structu
