It is cast-in-place to form.
Preferably, the bottom steel plate is complete steel plate, is attached and Transfer of Shear by peg and cast-in-place concrete,
So as to form entirety.
Preferably, the two-way honeycomb riser is formed by steel plate cutting, and bidirectional arrangements are vertically welded in the bottom steel
Cellular riser on plate, is easy to the bidirectional arrangements of bottom two-way concrete slab and the two-way free-flowing of cast-in-place concrete, it is ensured that
Cast-in-place concrete it is closely knit.
Preferably, the two-way honeycomb riser increases rigidity by welded top two-way steel lath band, so as to ensure lifting
Smooth and control casting concrete the template deformation of steel plate.
Compared with prior art, the invention has the advantages that：
1st, the two-way steel plate concrete composite floor that the present invention is provided, had both met construction, lifting and casting concrete etc. and had applied
Work requirement, and bidirectional stress feature is met from construction.
2nd, the two-way steel plate concrete composite floor that the present invention is provided, bottom steel plate two-way stiffness is preferable, is conveniently lifted into
Position, and can be as the template of concrete, convenient construction, reduction template cost；Two-way honeycomb riser and its top steel plate strip band
Combination both can guarantee that bottom steel panel stiffness, reduced steel using amount, and circulation and bottom reinforcement bars when can facilitate concreting again are worn
Cross；The present invention ensure that the two-way bearing capacity and stiffness of composite floor from construction, when improve composite floor bidirectional stress
Bearing capacity performance.
