Background
The cast-in-place concrete hollow floor slab is a new structural technology developed for meeting the requirement development of the times, and meets the requirements of large-space and large-span column nets for residences and public buildings. The cast-in-place beam floor system has the advantages that the number of secondary beams is large, the main beam is large, the occupied effective space is large, the building weight is also large, the cast-in-place hollow floor system is adopted, the secondary beams are not used, the peripheral beams are flat, the building weight is reduced, compared with the cast-in-place beam floor system, the floor height can be reduced to about 350mm, and the cast-in-place beam floor system has certain comprehensive economic advantages.
The BDF thin-wall box body is a cast-in-place concrete hollow floor internal mold form newly developed in the years. The BDF box body is a full built-in core mould, can effectively restrain the deformation and deflection of cast-in-place concrete, and has the advantages of light weight and high strength. The concrete is greatly pumped out, the self weight of the floor slab is reduced, the bending rigidity of the floor slab is increased, the using amount of reinforcing steel bars is reduced, the loss of construction templates is less, the construction is simple and convenient, the construction period is saved, and the economic benefit is good. And the problems of large span and large bay of the building are well solved, so that the building has the excellent performances of light dead weight, heat insulation, heat preservation, sound insulation, flexible space spacing, same bidirectional stress and force transmission, small deflection deformation, good shearing resistance and torsion resistance and good shock resistance.
The BDF ribbed steel mesh hollow component is a novel hollow box body, and compared with a BDF thin-wall box body, the BDF ribbed steel mesh hollow component has the absolute advantages of small dead weight and simple and convenient construction operation. Due to the characteristic that the BDF ribbed steel mesh hollow component box body is small in self weight, in the concrete pouring process, the BDF ribbed steel mesh hollow component box body is easy to displace due to the buoyancy of liquid and mainly shows upward floating and inclination, and the maximum displacement namely upward floating is from the top to the epithelial steel bar, so that the effective bond between the epithelial steel bar and the concrete is influenced; and because box self is steel mesh fretwork component, can the infiltration concrete slurry in the box, not only increase buoyancy, if the infiltration volume is too big, its box weight increases, and the load value will be greater than the design pressure value, can not satisfy the design requirement.
