The invention relates to a column clamp for concrete shutterings, having sides (1) keyed to form a polygonal frame, and proposes, for improved use, in particular separation and better keying, that each side (1) be of double-layer design over its entire length, leaving open a slot which extends between the two layers and through which passes a tab (1) which projects in each case at one end of each side (1) and can be clamped by the key (16) and against the longitudinal flank of which can be clamped a second key (17) which is driven into one hole (15) of a series of holes extending in the sides (1) over their entire length. <IMAGE>
