Mould for molding concrete filled hollow thin wall component

Abstract

The invention provides a mould for moulding a concrete filled hollow thin wall component, which comprises templets (1), fasteners (2) and rotary components (3). The templets (1) are connected with each other by the rotary components (3); the connected templets (1) can turn relatively; after the templets are folded, the fasteners (2) fix the templets (1). The mould for moulding the concrete filled hollow thin wall component is characterized in that at least three templets in the mould are connected in turn side by side; at least one templet (1) is provided with at least one cross spacing mould (4) which consists of at least two movable components (5) through assembly; the surface of the cross spacing mould is a moulding surface. In this way, after the fasteners become loose, the mould can be unloaded conveniently. When polyhedral components are produced, the mould can form concave structures on the polyhedral components, or be used for manufacturing connected or disconnected polyhedral components. Accordingly, the mould meets the requirements for producing various polyhedral components. In addition, the mould has the characteristics of simple structure, being manufactured easily, high strength, low cost and so on, which is applicable for manufacturing various open-end or closed-end polyhedral 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...

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
