Mold for molding hollow thin wall component for filling concrete

Abstract

A concrete filled hollow thin wall element forming die comprises moulding boards (1), a rotatable component (2) and a clamping piece (3), wherein, the moulding boards (1) are connected by the rotatable component (2); and the moulding boards (1) are clamped by the clamping piece after being shut. The forming die is characterized in that all the surfaces formed by shutting the moulding boards (1) are spliced by polyhedron bodies covered by the moulding boards; the moulding boards (1) are tabular elements; the modular surfaces on the same surface of the polyhedron splicing forming die comprise a moulding board (1); and the moulding boards (1) are moulding boards for the hollow thin wall element to lay a slurry blank body (22). Therefore, the forming die is suitable for manufacturing various open-ended or closed polyhedron elements.

Description

[0001] This application is a divisional application of the patent application with the application number 200410155191.5 and the application date is July 29, 2004, and the title is "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 interface Th...

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.
