Formation type null for large-sized concrete block

摘要

PURPOSE:To safely and easily perform separation and attachment, opening and closing and attachment by introducing concrete into a forming mold and advancing a molding front frame by a transfer device after curing and opening a molding side form to the outside by an opening and closing device and pulling up a product to the upper part and demolding the product. CONSTITUTION:In the case of molding, a molding front form 3 is joined to a forming mold body 1 by a transfer device 4. This state is maintained by a clamping device 7 of the front form and a molding side form 5 is closed by an opening and closing device 6. The front edge of the molding side form 5 is brought into contact with the side face of the molding front frame 3 and the side face of the forming mold main body 1 and maintained by the clamping devices 8, 9 of the side frame. When the transfer device 4 is operated and driven after concrete introduced into a forming mold (a) is cured, the molding front form 3 of the forming mold (a) is moved to the outside on an underframe 2 while keeping an erecting state and separated from the forming mold main body 1. Further when the opening and closing device 6 is operated and driven, the molding side form 5 is opened a little to the outside and the part near to the front edge of the molding side form 5 is separated from the forming mold main body 1 and the molding front form 3. A hardened product is pulled up to the upper part from an opening port by a pulling-up device, demolded and lowered on the ground. Thereby demolding work is completed.
