Problems solved by technology

However, the half part of this hollow thin-walled member cannot be folded into a plate shape, so the space occupied during transportation is still large, and the transportation volume is still small each time. Therefore, a new type of cast-in-place concrete is developed. The hollow mandrel for hollow filling is urgently needed

Embodiment Construction

[0100] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0101] As shown in the drawings, the present invention has reinforcing ribs 5 on the outer wall 1 of the mandrel, and at least one hinge 2 on the outer wall 1 . In each accompanying drawing, 1 is a tube wall, and 2 is a hinge. In each of the following accompanying drawings, those with the same number have the same description. As shown in FIG. 6 , ribs 5 are arranged on the outer wall 1 of the mandrel, and hinges 2 are arranged on the outer wall 1 .

[0102] As shown in the accompanying drawings, the present invention comprises a mandrel outer wall 1 and a cavity closed by the outer wall 1, and is characterized in that there are reinforcing ribs 5 on the outer wall 1, at least one hinge 2 on the outer wall 1 and at least one so that the outer wall 1 does not The fixed hinge member 3 that rotates along the hinge 2. As shown in FIG. 7 , there are reinfo...

Abstract

The present invention relates to a hollow core mould for filling concrete. It includes an external wall of said core mould and a closed hollow cavity enveloped by said external wall. It is characterized by that on the described external wall a reinforcing rib is set, and on the external wall at least a hinge also is set, so that when the external wall is hollow perforated external wall and on the external wall at least one hinge is set, the self-weight of said hollow core mould is small, said hollow core mould can be folded into plate-sheet form. Said hollow core mould is convenient for transportation, storage and construction, and can be used for in-situ casting various reinforced concrete or prestressed reinforced concrete hollow plates, hollow floor, roof, foundation bedplate, wall body and open-web bridge, etc.

Description

(1) Technical field [0001] The invention relates to a hollow mandrel for pouring-in-situ concrete hollow filling. (2) Background technology [0002] At present, in the prior art, the hole-forming member of the cast-in-place reinforced concrete hollow slab is a permanent mandrel, such as a paper tube, a plastic tube, a metal bellows, and a mandrel made of lightweight materials. These tubular mandrels or components are mainly considered to evacuate the concrete and reduce the weight of the hollow slab. For example, the patent No. ZL99249775.8 applied by the applicant is a utility model patent named "fiber-reinforced thin-walled tube for filling cast-in-place reinforced concrete". It consists of a hard thin-walled tube and plugs at both ends. The two ends of the hard thin-walled tube are closed to form a closed cavity. The hard thin-walled tube wall is composed of a carcass and a cementing material. The carcass can be glass fiber or carbon fiber or organic fiber or non-woven f...
