ABSTRACT:
A shuttering apparatus includes at least two rectangular shuttering panels (22, 22') which have a plurality of bores of the same dimensions which extend along at least one edge (13, 15) in a row parallel to the edge and are arranged in accordance with a grid dimension at grid points having the same spacing. The bores have axes extending perpendicular to the edge. The shuttering panels are capable of being placed together with their edges containing the bores (11, 11') being so aligned that several connection bores (11, 11') of the one shuttering panel are aligned with several connection bores (11, 11') of the other shuttering panel. In this way a form locked connection of the shuttering panels (22, 22') in the direction of the edge (13, 15) which contains the lines of bores can be brought about by fitted connection pins which are placed through at least some of the aligned bores (11, 11') of the two shuttering panels (22, 22'). Only some of the mutually associated connection bores (11) are arranged at the grid points (12) at the edges of each shuttering panel. The other connection bores (11') are displaced by less than half the grid point spacing (a) relative to the grid points (12) and indeed in the one shuttering panel (12) in the opposite direction to those of the other shuttering panel (22').
