Embodiment Construction
[0053] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0054] As shown in the accompanying drawings, the present invention includes a template 1, a rotatable part 2, and a fastening member 3. The template 1 is connected side by side by the rotatable part 2 in sequence, and the connected template 1 can rotate relatively. After the template 1 is closed, the fastening part 3 Closed and fixed to form a multi-sided cylindrical mold, which is characterized in that at least four templates 1 are connected side by side by rotatable parts 2 in sequence, the closing part 4 of the template 1 is set at the corner part 5, and the templates 1 are docked and overlapped at the closing part 4 , at least one end of at least one of the templates 1 connected side by side is provided with a movable template 1; or the two ends of at least one template 1 connected side by side are provided with a movable template 1; or the movable ...

A tubular die for forming a concrete filled hollow thin walled member comprises die plates (1), rotatable parts (2) and tightening parts (3). The die plates (1) are connected side by side in sequence through the rotatable parts (2); the connected die plates (1) can relatively rotate; and the die plates (1) are fixed through the tightening parts (3) after being closed to form the multi-surface tubular die. The tubular die is characterized in that at least four die plates (1) are connected side by side in sequence through the rotatable parts (2); the closing parts (4) of the die plate (1) are positioned on turning parts (5); the die plates (1) are butted and lapped on the closing parts; and a moveable die plate (1) is arranged on at least one end of at least one die plate of the die plates (1) which are connected side by side. In this way, after a tightening part is screwed loose, demoulding is very convenient. The tubular die has the advantages of simple structure, easy manufacture, high strength, low cost, and suitability for manufacturing various open or closed polyhedron 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 200410155173.7, and a title of "a cylindrical mold for forming a concrete-filled hollow thin-walled member". (1) Technical field [0002] The invention relates to a cylindrical mold for forming 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 ...
