Mold for molding hollow thin wall component for filling concrete

Abstract

The invention relates to a concrete-filled hollow thin-walled member forming mould which comprises templates (1), a joint and tight piece (2), and rotatable components (3). The templates (1) are connected by the rotatable components (3). The connected templates (1) can relatively rotate. After the templates (1) are folded, the templates are fixed by the joint and tight piece (2). The mould is characterized in that at least three templates (1) are sequentially connected with each other side by side in the mould; wherein, a projection (4) or sand strip (5) protruding the surface of the templates is arranged on at least one of the three templates. The projection (4) or the sand strip (5) is fixedly or movably connected with the templates (4) or the sand strip (5) is parallel to or vertical to the rotatable axes of the rotatable components (3). At least one of a gemel, a hinge, a bolt hinge, a film, a rotatable tenon, a rotatable slot or a rotatable jack, a rotatable bolt, a rotatable connector pin and a rotatable sliding bush serves as the rotatable components (3). Therefore, a very convenient demoulding can be ensured after the joint and tight piece is loosed; at the same time, a concave structure can be correspondingly formed on the polyhedron members during the production of polyhedron members, thus meeting requirements for a variety of hollow floor systems; furthermore, the mould is characterized by simple structure, easy manufacture, high intensity, low cost, and the like, and is suitable for manufacturing a variety of open or closed polyhedral components.

Description

[0001] This application is a divisional application of the invention patent application with the application number "200410155180.7", the application date is July 28, 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 inte...

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. In the middle, it is inconvenient to demould, and the open thin-walled tube or thin-walled box is easy to be damaged. Therefore, it is urgent to develop a new type of polyhedral component forming mold.
