An extruded profiled main beam (11) for a concreting formwork has a plate-like upper wall (16) which projects beyond the side walls (21, 22). The side walls thus set back provide room for dirt gutters (63, 64) on both sides, at the transition to suspension gutters (53, 54) for the connection of further beams (11). Any dirt (concrete milk) which drips down can thus be kept away from the suspension gutters more effectively. Moreover, the dirt gutters have a stepped gutter bottom (73, 74), so that dirt which has penetrated can nevertheless run off unimpeded. <IMAGE> |
