The distance holder bar, for concrete reinforcement material, has recesses (17) with virtually vertical walls (18) to hold the reinforcement material. Pref. the distance holder bar is shaped in a profile in a Y-, L-, H- or U-shape, with openings (14) in the side walls (11) for the concrete to flow through. With an H-profile, the web (13) connecting section has flow openings for the concrete. The web (13) is virtually half the height, with identical upper and lower recesses (17) to be used selectively to hold the reinforcement material, or the upper and lower recesses have different depths. The recesses (17) in each arm of a Y-shape have different depths. The Y-shape arms are at 120 deg. to each other, and are of the same lengths or one arm has a different length. USE/ADVANTAGE - The distance holder bar, to hold the reinforcement material, has holding recesses at the top separated by a screen interval. The bar structure holds the reinforcements securely at the sides.
