Mold for molding hollow thin wall component for filling concrete

Abstract

A forming die of a concrete filled hollow thin-walled component comprises die plates (1), a clamping piece (2) and a rotatable part (3); the die plates (1) are connected by the rotatable part (3), the connected die plates (1) can rotate correspondingly, and after being folded, the die plates (1) are fixed by the clamping piece (2); the forming die is characterized in that: the forming die is internally provided with at least three die plates (1) which are sequentially connected side by side, at least one transverse spacing mould (4) is arranged on at least one die plate (1), five die plates (1) are sequentially connected side by side and folded to form a tubular die, and the surface of the transverse spacing mould (4) is a forming die surface; in this way, when the clamping piece is loosened, the die can be demoulded conveniently; Meanwhile, in the process of producing polyhedral components, a concave structure can be correspondingly formed on the polyhedral components, or connected or unconnected polyhedral components can be manufactured, thus meeting the requirements for producing various different polyhedral components; in addition, the forming die has the advantages of simple structure, easy manufacturing, high strength, low cost, and the like; furthermore, the forming die is suitable for producing various opens or closed 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...

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
