A cast-in-place hollow floor with holes formed by combined mesh box-shaped components

Abstract

The invention provides a cast-in-situ hollow floor with pores formed by a combined reticular box-shaped component. The cast-in-situ hollow floor comprises a reinforced concrete girder or a profile steel concrete girder, a reinforced concrete ribbed beam, an upper flange plate, a lower flange plate and the combined reticular box-shaped component, wherein the combined reticular box-shaped component comprises a box roof, a box body and a box bottom; the box body and the box bottom are made of reticular bodies; reinforcing ribs of the reticular bodies are vertically placed; each reticular body comprises a reticular plate, the reinforcing rib and a connecting piece, which constitute an integral structure; the lower flange plate is directly compounded with the reticular bodies at the box bottom of the combined reticular box-shaped component. The cast-in-situ hollow floor with the pores formed by the combined reticular box-shaped component adopts the unsealed combined reticular box-shaped component to substitute the existing fully-sealed hollow fillers and solid fillers as the cast-in-situ hollow floor pore-forming technology. The cast-in-situ hollow floor with the pores formed by the combined reticular box-shaped component is beneficial to realization of energy conservation integration of a building and the multifunctional use of hollow floor.

Description

Technical field [0001] The invention relates to a cast-in-situ hollow floor with holes formed by non-cored hole forming members, in particular to a cast-in-situ hollow floor with holes formed by a combined mesh box-shaped member. Background technique [0002] At present, in the field of cast-in-situ reinforced concrete hollow floor technology, fully-sealed filler members are usually used to cast the hollow hollow floor, such as ZL02282207.0 "thin-walled box embodies thin-walled box for pouring hollow web" declared by the inventor. According to the patent, inorganic cementitious materials are used to make a sealed filling body to realize the hollow floor, which provides a non-cored hole filling body for the realization of the cast-in-place hollow floor. However, due to the hollow filler made of pure inorganic cementitious materials, the sealed hollow filler has high buoyancy, the cement cement material is dense and heavy, and it is inconvenient for production, transportation and o...

Problems solved by technology

When the "T" shaped stress section is used, although the buoyancy is reduced, there is no designed stress reinforcement between the bottom of the filling body and the hollow floor formwork, and a layer of crack-resistant steel mesh must be applied separately, and full-length reinforcement and Defects such as fixed spacer, heavy filling, inconvenient production and transportation, large volume and easy damage of filling

[0004] At the same time, the applicant invented a method of making cavity components using a mechanical mold system (ZL201110258028.1), which realized mechanized production of hole-forming components for hollow floors; solved the problems of heavy filling, inconvenient production and transportation, and overall The problem of poor performance and easy damage, but the buoyancy has not been completely solved; the applicant also invented a hollow floor made of reinforced foam composite filler (ZL201110332999.6), this technology solves the problem of existing technology of cast-in-place hollow floor Displacement, isolation, pads, fixing the filling body with long steel bars, and easy damage; at the same time, it has the advantages of fast production speed, high production efficiency, low cost, convenient construction, and can prevent the steel bars from falling into the plastic foam filling components. engineering hidden dangers

However, since the plastic foam filling components are organic materials, the combination of organic materials and inorganic materials has high control accuracy, the overall buoyancy increases, and the formed hollow floor is essentially solid, which affects the storage of solar heat and the transmission of thermal wind energy. Or the defect of multi-functional comprehensive utilization of dark smoke exhaust pipes for ventilation ducts and fire protection
