Embodiment Construction

[0026] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0027] As shown in the accompanying drawings, the present invention includes a cavity mold 1, which is characterized in that it also includes a structural bottom plate 2. The structural bottom plate 2 is connected with the cavity mold 1 to form a polyhedral structure. The cavity mold 1 is a blow molded part with Inflatable mouth3. figure 1 It is a structural schematic diagram of Embodiment 1 of the present invention. In each accompanying drawing, 1 is a cavity mold, 2 is a structural bottom plate, and 3 is an air filling nozzle. In the following accompanying drawings, those with the same number have the same description. Such as figure 1 As shown, the cavity mold 1 and the structural bottom plate 2 are connected to form a polyhedral cavity member, and the cavity mold 1 is a blow molded part, and the blow molded part is also provided with an inflation ...

Abstract

The present invention relates to a hollow cavity member, including hollow cavity mould. It is characterized by that it also includes structure bottom plate, said structure bottom plate and hollow cavity mould are connected and formed into a polyhedral structure. The hollow cavity mould is a blow-moulded product equipped with an air-charging connector. Said hollow cavity member is light in weight, and is applicable to various cast-in-situ concrete floor, roof, wall body, foundation bedplate and structure of road and bridge engineering, specially applicable to hollow beamless floor.

Description

(1) Technical field [0001] The present invention relates to a cavity member. (2) Background technology [0002] At present, in the prior art, the thin-walled cavity components used for cast-in-place reinforced concrete hollow slabs include paper tubes, plastic tubes, metal hollow tubes, hard thin-walled tubes, thin-walled membrane shell components, mandrels, etc. These thin-walled cavity components are mainly considered to evacuate the concrete to reduce the weight of the floor slab. For example, the patent No. 99249755.8 is the utility model patent of "fiber-reinforced thin-walled tube for filling cast-in-place reinforced concrete", which consists of a hard thin-walled tube and plugs at both ends. Form a closed cavity, the cross section of the hard thin-walled tube and the shape of the plug can be round, square, trapezoidal or other irregular shapes. After the body is wound and formed, the single-layer or multi-layer fiber cloth pipe with cement slurry is covered to block...
