A bar unit, formed of longitudinal interconnected strips of spaced angled profiles, leaving a front longitudinal unobstructed slit, and a back slit, broken by cross straps but permitting manual access to the back of the bar unit, has braces, adapted to be secured to concrete form or mold boards attached thereto by brace clamps which contain screw-clamping elements, the clamp elements penetrating through the front slit to provide clamping pressure against the front faces of the profile. The profiles are interconnected, or connectable to further brace clamps, by means of inserted coupling bars, telescopically receivable in the bar unit, and held therein by coupling clamps utilizing counter plates pressing the coupling bars against the profiled faces of the strips of the bar unit, to form a rigid, interconnectable structure, which is longitudinally adjustable and on which the form braces can be placed, as desired, and in accordance with load requirements.
