ABSTRACT:
A method for assembly and disassembly of formwork for walls (1) of poured material raised above a reference surface (2) using boards (3) each including a shuttering face (4) and equipped with wheels (31, 32) at their base. Assembly includes from an unshuttered position, rocking toward the wall (1) to be shuttered of at least the base (29) of the shuttering face (4) of the board (3) by rotating about an axis defined substantially by the support points (10) of the wheels (31) on the reference surface until the lower edge (35) of the shuttering face (4) is made to rest on the reference surface (2). The rocking is continued toward the wall (1) to be shuttered of at least the base (29) of the shuttering face of the board (3) by rotating about an axis substantially defined by the lower edge (35) of the shuttering face of the board (3) until the wheels (31) are raised from the reference surface. For disassembly, the rocking about the two axes is performed in reverse.
