Problems solved by technology

However, this kind of thin-walled box formwork member, as an integral thin-walled box member, takes up a lot of space during transportation, the quantity of each transportation is small, and the transportation cost is high, which undoubtedly increases the production cost of the thin-walled box and the cast-in-place reinforced concrete. The construction cost of the hollow slab, therefore, the development of a new type of hollow member is urgently needed

Embodiment Construction

[0034] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0035] As shown in the accompanying drawings, the present invention includes a polyhedral outer wall 1, the outer wall 1 encloses a cavity polyhedron, and is characterized in that at least one intersecting line on the outer wall 1 surface is a hinge 2, and the inner or outer surface of the outer wall 1 has parallel or The intersecting ribs 4 and the polyhedral outer wall 1 can be folded into a box shape, and can be spread out into a single-layer or / and double-layer plate shape. At least one circle of the outer wall 1 is joined by the joint 3 of the longitudinally opposite body. In each accompanying drawing, 1 is an outer wall, and 2 is a hinge. In each following accompanying drawing, those with the same number have the same description. As shown in Figure 4, the hollow member includes a polyhedral outer wall 1, the outer wall 1 encloses a cavity polyhed...

Abstract

The present invention relates to a hollow member. It includes a polyhedral external wall, said polyhedral external wall can be formed into a hollow cavity polyhedron, and is characterized by that at least one crossing line on the described external wall surface is a hinge joint, on the internal surface or external surface of said external wall the parallel or crossed strengthening ribs are set, said polyhedral external wall can be folded and made into the form of box, and can be spread to form single layer or double-layer plate-sheet form. Said hollow member can be used for in-situ casting reinforced concrete or prestressed reinforced concrete hollow plate, hollow floor, roof, foundation bedplate, wall body and open-web bridge, etc.

Description

(1) Technical field [0001] The invention relates to a hollow component. (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 paper tubes, plastic tubes, metal bellows, hollow form shells, and lightweight materials for mandrels. These tubular mandrels or hollow components are mainly considered to evacuate the concrete and reduce the weight of the hollow slab. For example, the patent No. ZL99249798.1, which the applicant applied for on November 29, 1999, is a utility model patent named "fiber-reinforced thin-walled member for reinforced concrete filling", which discloses a thin-walled formwork member, including an upper plate, The surrounding side walls, the lower bottom, and the upper plate, the surrounding side walls and the lower bottom form a polyhedral cavity. Another example is that the application number applied by the applicant on November 23, 2001...
