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), rotatable components (3) and a joint and tight piece (4). The mould is characterized in that the mould also comprises die block frameworks (2); at least four templates (1) or the templates and die block frameworks (1) are connected by the rotatable components (3); the connected templates (1) can relatively rotate; wherein, at least two templates (1) are sequentially connected with the die block frameworks (2) by the rotatable components (3); after a plurality of templates (1) are folded with the die block frameworks (2), a plurality of templates (1) and the die block frameworks (2) are jointed and tighten to form the mould by the joint and tight piece; a plurality of templates (1) and the die block frameworks (2) are folded to form an open-ended mould without an end plate; at least one of a plurality of templates (1) or die block frameworks (2) is scalable, the scalable position is provided with at least one of a projection (5), a sand strip (6), and a socket (7), a concave lump (8), and a hole cave is arranged where the templates or die block frameworks are scalable. The mould is suitable for manufacturing a variety of open ended or closed polyhedral members.

Description

[0001] This application is a divisional application of an invention patent application with an application date of July 28, 2004, an application number of 200410155178.X, and a title of "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 interfac...
