Abstract

The utility model discloses a novel compound internal mold for a cast-in-situ concrete hollow floor, which comprises a cover and a mold body, and the housing of the mold body adopts a honeycomb hollow shape. A supporting structure can be arranged in the compound internal with the purpose of enhancing intensity. The compound internal mold provided by the utility model has the advantages of high total intensity, light dead weight, low cost and the like.

Description

Cast-in-place concrete hollow building roof NEW TYPE OF COMPOSITE internal mold

Technical field

The utility model relates to a kind of prefabricated component in the building field, in particular, relates to a kind of a kind of prefabricated composite internal mould structure that is used for the cast-in-place concrete hollow building roof pore-forming.

Background technology

In building field, this form of structure of cast-in-place concrete hollow building roof is often adopted, cast-in-place concrete hollow building roof is exactly after placing the flush type internal mold by certain rule, in floor, form the superstructure of cavity through poured in place concrete, the prefabricated internal mold that its pore-forming is used, generally be divided into papery, plastics, metal and cement etc., its cross section can be circle (tube core), rectangle (casing), trapezoidal or other shape.Paper internal mold is non-watertight and intensity is low, and the metal internal mold does not have because of cost is too high to adopt in a large number in engineering.Because cement internal mold cost is low, so often be used, but in practical engineering application, because it is from great, the percentage of damage height, infringement is serious, the size and the cross sectional shape of cast-in-place concrete hollow building roof have been had a strong impact on, make the structure tension performance instability, can't reach designing requirement, thereby bring hidden danger for the safety of building.

Summary of the invention

In order to overcome above shortcoming, the purpose of this utility model is to provide a kind of intensity height, from heavy and light, and the novel cast-in-place concrete hollow building roof composite internal mould that cost is low.

Goal of the invention of the present utility model is achieved by the following technical solution:

A kind of cast-in-place concrete hollow building roof NEW TYPE OF COMPOSITE internal mold comprises lid and die body, and the shell of described die body is the shell of cellular hollow form.Also can inner supporting structure be set in order to gain in strength in the inside of compound die body.

Described die body adopts materials such as plastics, wood are moulded, PVC, PE, PP, ABS, metal to make.

The cross section of described composite internal mould structure can be circle (tube core), rectangle (casing), trapezoidal or other shape.

Composite internal mould of the present utility model has been owing to made the shell of hollow (cellular-shaped) structure with the shell of die body, and adopted composite material, therefore has the bulk strength height, from heavy and light, and advantage such as cost is low.

The specific embodiment

Further the utility model is described in conjunction with the accompanying drawings.

Embodiment

A kind of cast-in-place concrete hollow building roof NEW TYPE OF COMPOSITE internal mold comprises lid 1 and die body, and the shell 3 of described die body is the shell of cellular hollow form.Also inner supporting structure 4 can be set in the inside of compound die body in order to gain in strength.

As shown in Figure 1, for the utility model composite internal mould cross section is the structure of rectangle (casing), compound die body by go to the bottom 2 and the die body shell of lid 1 and hollow form, in order to gain in strength, to be provided with in the centre of casing and to support 4 structures (as shown in Figure 2) in one.After braced structures is arranged, can with lid and the end, also be designed to hollow loam cake 6 and hollow was gone to the bottom for 7 (as shown in Figure 3).

As Fig. 4, shown in Figure 5, for the utility model composite internal mould cross section is the structure of circular (tube core), compound die body is made up of the die body shell 3 of lid 1 and hollow, also can establish braced structures in inside, makes it more firm.

As Fig. 6, shown in Figure 7, for the utility model composite internal mould cross section is the structure of polygon (eight limits) shape, compound die body is made up of the die body shell 3 of lid 1 and hollow, also can establish braced structures 4 in inside.

Claims

1. a cast-in-place concrete hollow building roof NEW TYPE OF COMPOSITE internal mold comprises lid and die body, it is characterized in that: the shell of described die body is the shell of cellular hollow form.

2. a kind of cast-in-place concrete hollow building roof NEW TYPE OF COMPOSITE internal mold according to claim 1, it is characterized in that: the inside of described compound die body is provided with inner supporting structure.

3. a kind of cast-in-place concrete hollow building roof NEW TYPE OF COMPOSITE internal mold according to claim 1 is characterized in that: described die body adopts that plastics, wood are moulded, polyvinyl chloride, polyethylene, polypropylene or ABS material make.
