ABSTRACT:
A forming device includes two opposite form boards, an upper fastening unit mounted on the first and second top ends of the form boards, an upper hydraulic drive unit cooperably connected to the fastening unit and a lower hydraulic drive unit mounted on the bottom end of the first or second form board. The fastening unit includes a slide device to permit the first and second form boards to move away from one another or to approach one another. The slide device includes a slide bar fixed to the first or second top end of the form board, and a support bar fixed to the second or first top side. An upper hydraulic drive unit is cooperably connected to the slide bar and the support bar. A lower hydraulic drive unit is mounted on the bottom end of the first or second form board to move the form board relative to the formed concrete. The form boards can be stripped from a formed wall in a proper direction without causing the boards to swing and possibly damage the projecting portions of the formed wall.
