Abstract
PURPOSE:To prevent the deformation of flexible panels upon placing concrete and obtain a molded form having a high accuracy, by a method wherein the back surface of the flexible panel is abutted against the backup surface of a spacer to preclude the inward deformation of the flexible panel due to an external pressure. CONSTITUTION:End rims of neighboring surface plates 4, 5, pinching a space 6 into which a spacer 7 is fitted, are connected with each other by flexible panels such as thin metallic panel 31, a rubber plate 18 or the like while the back surfaces of the panels 18, 31 are backed up by the spacer 7. Both ends of the plate bodies 18, 31 are fixed to the end rims of respective surface plates 4, 5 and the outer surface 23 of the surface plates 4, 5 are connected to forming surfaces 24, 25. When a spacer 7 is advanced, a core mold 29 is expanded by the insertion of the space 7 into the space and the inward deformations of the flexible panels 18, 31 due to an external pressure are precluded, therefore, deformation will never be generated and a product having a predetermined configuration can be molded.
