The improvements consist in the provision of a series of frames 1 articulated via one of their vertices 4 and with closure means 6,7 at the opposite vertex, which in the open position, and placed parallel and successively on the floor, allow the nailing (stock of nails) of longitudinal panels 9 which are to form the mould for the pillar, provision having been made in one of such frames for an engagement element 10 for raising the closed assembly of the frames 1 and panels 9 and for placing it vertically in order to commence the operation of filling the actual shuttering. <IMAGE>
