The arrangement comprises a foundation beam (1) with spaced apart holder plates (2) protruding from its top side and extending in the beam cross-direction. Pyramid or prism-shaped guides (3, 21) located in a central position above the beam are oriented with their pointed ends facing upwards. A cavity or groove in the upper edge of the plate is used to locate one or more reinforcing bars. The space between the foot of the plate and one of the base edges of the guide is adapted to locate the base of a triangular-shaped beam waist section. - At least one reinforcing bar (13) is intended for casting in a first flange (19) and at least two reinforcing bars (14, 14) are designed to be cast in a plate or a second lower flange (20). The two flanges are connected via bent triangular-shaped beam waist sections with their bases at the bottom. |
