Molding die of concrete-filling hollow thin-wall member

Abstract

A molding die of a concrete-filling hollow thin-wall member comprises a template (1), a rotatable part (2) and a fastening piece (3), wherein the template (1) is connected by the rotatable part (2) and rotates relatively around the rotatable part (2); moreover, the template (1) is combined into a barrel-shaped split-type die; and the split-type die is fastened by the fastening piece (3). The molding die is characterized in that the template (1) is a plate member; the same die surface of the barrel-shaped split-type die comprises at least one template (1); a permanent support die (6) is a stiffening rib, a stiffening rod, a reinforcing rib, a slab or a combination of the parts; the barrel-shaped die is also provided with a joint piece (20); and the joint piece (20) is fixed on the edge of the template (1) on a closure part (4). The molding die is suitable for manufacturing various open or close polyhedral members.

Description

[0001] This application is a divisional application of an invention patent application with an application date of July 28, 2004, an application number of 200410155183.0, and a title of "a mold for forming hollow thin-walled components filled with concrete". (1) Technical field [0002] The invention relates to a molding die for a concrete-filled hollow thin-walled component. (2) Background technology [0003] At present, cast-in-place reinforced concrete hollow slabs, especially the non-core-pulling hole-forming process of cast-in-situ reinforced concrete hollow slabs, are generally filled with thin-walled tubes or thin-walled boxes, which can meet the needs of various hollow slabs for evacuating concrete. For example, the publication number applied by the applicant on May 29, 2002 is CN1462680A, and the title is "Hollow Tube Forming Tool", which is characterized in that it includes two interface edges, a stretchable elastic cylinder, a brace, a tightening piece, an interfac...

Problems solved by technology

Such as the female mold, as can be seen from their drawings, it includes a side mold surface and a bottom mold surface, and the side mold surface and the bottom mold surface form a female mold. This kind of female mold is the female mold of the overall template. Among them, the demoulding is inconvenient, and the open thin-walled tube or thin-walled box is easily damaged. Therefore, it is urgently needed to develop a new type of concrete-filled hollow thin-walled component forming mold.
