Mold for molding hollow thin wall component for filling concrete

Abstract

A shaping die for a concrete-filled hollow thin-wall component includes templates (1), fasteners (2) and rotatable parts (3). The templates (1) are connected by the rotatable parts (3); the connected templates (1) can rotate oppositely; the templates (1) after being folded are fixed by the fasteners (2). The invention is characterized in that at least three templates (1) are connected in sequence side by side in the die; at least one template (1) is provided with at least one transverse isolating die (4); at least one end of at least one of the side-by-side templates (1) is connected with a movable template (1); the surface of the transverse isolating die (4) is a shaping die surface. In this way, after the fasteners are loosened, the die is very convenient to be released; simultaneously, when a polyhedron component is produced, a concave structure can be correspondingly formed on the polyhedron component; the production requirements for different polyhedron components can be met; besides, the die is also characterized by simple structure, easy manufacture, high intensity, low cost, and the like. The shaping die for a concrete-filled hollow thin-wall component is applicable to manufacturing various opened or closed polyhedron components.

Description

[0001] This application is a divisional application of the invention patent application with the filing date of July 28, 2004, the application number of 200410155175.6, and the title of "a molding die for 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...

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, it is inconvenient to demould, open thin-walled tubes or thin-walled boxes are easily damaged, and more importantly, it is impossible to produce conjoined products or products with spacing
