Netlike box-shaped component for forming holes in cast-in-situ hollow floor

Abstract

The invention provides a netlike box-shaped component for forming holes in a cast-in-situ hollow floor. The netlike box-shaped component is formed by combining a box roof, a box body (side wall) and a box bottom; the box roof is compounded with cement mortar or styrofoam or a board; the box body and the box bottom are manufactured by netlike bodies; each netlike body comprises a netlike board, reinforcing ribs and connecting nets; the netlike board, the reinforcing ribs and the connecting nets form an interacting integral structure; the area of a grid in the netlike board is smaller than 120 mm<2>; the reinforcing ribs are V-shaped; the reinforcing ribs are higher than 3mm; the space between the reinforcing ribs in each netlike body is larger than 30mm; the netlike box-shaped component is formed by combining at least two netlike bodies; at least two structural inclined planes are arranged at corners of the box bottom and the box body of the netlike box-shaped component; the netlike bodies of the netlike box-shaped component are made of steel or plastic. 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 conventional cast-in-situ hollow floor, so that technical defects of the existing hollow floor are effectively solved.

Description

technical field [0001] The invention relates to a component for forming holes in a cast-in-place hollow floor, in particular to a reticulated box-shaped component for forming holes in a cast-in-place hollow floor. Background technique [0002] At present, in the technical field of cast-in-place reinforced concrete hollow floors, a fully sealed filling member is usually used to form a hollow floor, such as the ZL98231113.3 concrete thin-walled cylindrical member declared by the inventor, which is made into a sealed cylindrical filling body. In order to realize the cast-in-place hollow floor, a tubular hollow filling body is provided, which solves the technical problem of non-centering hole formation in the cast-in-place hollow floor. However, due to the existence of the sealed tubular hollow filling body, it is difficult to fix, the buoyancy is large, the density is high and the mass is heavy, and the production, transportation and on-site construction are all inconvenient, a...

Problems solved by technology

However, since the plastic foam filling components are organic materials, the combination of organic materials and inorganic materials has a large control accuracy, the overall buoyancy increases, and the formed hollow floor is essentially solid. Since the floor is not hollow, it affects the storage capacity.
