Embodiment Construction

[0054] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0055] As shown in the drawings, the present invention includes at least two templates 1, joints 2, rotatable parts 3, and fasteners 4. The templates 1 are connected by rotatable parts 3, and the connected templates 1 can rotate relatively. The joints 2 is set on the template 1, and the fastener 4 closes and fixes the template 1 to form a cylindrical mold, which is characterized in that at least one template 1 is a non-planar curled or folded plate template, and a non-planar curled or folded plate The formwork 1 is U-shaped, and the U-shaped formwork 1 and the plate formwork 1 are closed to form a cylindrical mold. At least one end of at least one formwork in the formwork 1 is connected with an end formwork 1; or at least one formwork 1 is a non-planar curl or folded plate formwork, the non-planar curled or folded plate formwork 1 is U-shaped, two U-sha...

Abstract

Disclosed is a cylinder-shape die for molding a concrete filling hollow thin-walled component, which at least includes two formworks(1), a connector(2), a rotatable part(3) and a fastener(4). The rotatable part(3) is used to connect the formworks(1), the connected formworks(1) can be correspondingly rotated, the connector(2) is arranged on the formworks(1), the formworks(1) are shut by the fastener(4)and are fixed to form the cylinder-shape die; the die is characterized in that at least one formwork(1) is an non-planar crimp-shape or folded plate-shape formwork(1), the non-planar crimp-shape or folded plate-shape formwork(1) are U-shape, the U-shape formwork(1) and the plate shape formwork(1) are shut to form the cylinder-shape die, at least one end of at least one formwork(1) in the formworks(1) is connected with an end formwork(1). Thus, after the fastener is loosened, the demoulding is very convenient. Moreover, the die also has the advantages that the structure is simple, the manufacture is easy, the strength is high, and the cost is low and the like. The die is applicable for producing various opened or closed polyhedron components.

Description

[0001] This application is a divisional application of an invention patent application with an application date of July 29, 2004, an application number of 200410155190.0, and a title of "a tubular mold for molding hollow thin-walled components filled with concrete". (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 tighteni...
