The round steel bent upper ring (20) and the lower ring (18) are fixed to one another coaxially and spaced apart by means of upright braces. The upper ring is reinforced by diagonal horizontal braces. In the reinforcement basket (10) a downwardly open, peripherally closed container (22) can be suspended, the ceiling wall (24) of which has ventilating holes (26). The container in the reinforcement basket is held at least approximately coaxially and the peripheral wall (28) of the container has at least approximately the same horizontal distances from the upright braces of the reinforcement basket. The basket is assembled from a number of U-stirrups (12) which cross one another in the yoke centre. They have teh same angle distances and their legs (14) represent the upright braces. |
