PROBLEM TO BE SOLVED: To provide a tool and a method for driving up a concrete product such as a concrete block for a retaining wall, when separating from a form. SOLUTION: An L-shaped concrete block 10 is manufactured, by setting a hanging tool 50 having a truncated cone-shaped support part 51 and a head part 55 in the shape of hooking a hook on its top in an inner form 31, to the inner form 31. The hook 61 of a suspender is hooked on the head part 55 of the tool 50, and the concrete block 10 is driven up, and is separated from the form 30. Afterwards, the tool 50 is removed from the concrete block 10, and can be reused. Since a through-hole 20 for inserting the tool 50 is molded in the concrete block 10, the concrete block can be driven up by using the tool 50. COPYRIGHT: (C)2008,JPO&INPIT
