The reinforcing steel bar net rack comprises a lower chord stress steel bar, a V-shaped web member steel bar, an upper chord reinforcing steel bar and transverse tie bars, wherein the lower chord stress steel bar, the V-shaped web member steel bar and the upper chord reinforcing steel bar are connected to form a stress net piece main body, and at least two stress net piece main bodies correspond to parallel arrangement and are connected through the transverse tie bars to form the reinforcing steel bar net rack.
The invention has the following advantages and positive effects:
1. the invention is widely used for large-span cast-in-place concrete hollow floor slabs, reduces the use of sub beams and columns, meets the requirement of large-span fabricated buildings on the basis of saving materials, improves the effect, reduces the construction cost of the buildings, increases the use space and ensures that the structural stress is more reasonable.
2. The prefabricated bar-shaped steel bar net rack hollow floor slab splicing device is simple and reasonable in structure, meets requirements of assembled components, is light in weight and reasonable in structure, can be used for splicing the prefabricated bar-shaped steel bar net rack hollow floor slabs processed in a factory one by one according to a drawing during construction, binding steel bars among boxes in the other direction of the vertical bar-shaped steel bar net rack hollow floor slab to form a stress rib beam in the other direction, the stress rib beams are uniformly distributed and placed without using cushion blocks and box positioning binding, the box floating and horizontal moving phenomena of the net rack hollow floor slab cannot occur, transportation and installation are convenient, the transportation quantity is greatly increased, the on-site splicing efficiency is high during construction, the labor intensity is low, the cost is low, the.
