Problems solved by technology

However, it is necessary to apply a layer of anti-cracking steel wire mesh separately, the filling body is heavy, the production and transportation are inconvenient, and the integrity of the filling body is large and easy to be damaged.
[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 However, the buoyancy has not been completely solved; the applicant also invented a hollow floor (ZL201110332999.6) made of reinforced foam composite filling body, which solves the problem of the existing technology of cast-in-place hollow floor. Existing problems of displacement, isolation, pads, fixing the filling body with long steel bars, and easy damage; at the same time, it also 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

Embodiment Construction

[0030] The present invention will be further described below in conjunction with the accompanying drawings.

[0031] figure 1 It is a cross-sectional view of the combined mesh box-shaped member of the first embodiment of the present invention, such as figure 1 As shown, the combined net-like box-shaped member is composed of a functional prefabricated board A1 and a net-like body A2. Among them, the combined mesh box-shaped component A includes a box top 1, a box bottom 2 and a box body 3. The box top 1 and the box bottom 2 are made of concrete mortar and reinforced materials under the action of a mechanical mold. For design needs, select functional prefabricated panels A1 of different shapes and specifications. The mesh body A2 is modulated and formed by the action of galvanized steel plate in special mechanical equipment. The mesh body A2 includes a mesh plate A21, a reinforcing rib A22 and a connecting piece A23, which connects the mesh body A2 into a cylindrical mesh body, cyl...

Abstract

The invention provides a combined netlike box-shaped component for forming holes in a cast-in-situ hollow floor. The combined netlike box-shaped component comprises a box roof, a box bottom and a box body, and consists of functional fabricated boards and netlike bodies, wherein the functional fabricated boards are manufactured from concrete mortar and a reinforcing material under the action of a mould or is compounded by superposing adhesive on the netlike bodies; each netlike body comprises a netlike board, reinforcing ribs and connecting sheets; the netlike board, the reinforcing ribs and the connecting sheets form an entirety; the area of a grid in the netlike board is smaller than 120 mm<2>; the netlike bodies are at least applied to the box body of the combined netlike box-shaped component; two structural inclined planes are arranged at corners of the box bottom and the box body. The combined netlike box-shaped component can form holes in the hollow floor; by virtue of surface tension of concrete, the unsealed netlike box-shaped component replaces a fully-sealed hollow filling body and a solid filling body as a hole forming technology of the existing cast-in-situ hollow floor, so that integration of building energy conservation and multifunctional utilization of the floor can be easily implemented.

Description

Technical field [0001] The invention relates to a non-cored hole forming component for cast-in-situ hollow slabs, in particular to a combined mesh box-shaped component for forming holes for cast-in-situ hollow slabs. 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 on-site constr...
