Title: Method for the manufacture of reinforcement members and member manufactured by the method

Abstract: A method for the manufacture of reinforcement members, in which steel rods are first bent into a U shape and the two arms of the U-shaped piece are then bent off at right angle, at a particular distance from the cross bar of the U. These steel rods are placed at preselected intervals of the U-shaped portion and with their bent-off arms lowermost, into a trough-shaped basin with outward sloping side walls. A liquid foam material is then brought into the basin so that the preshaped reinforcing rods will be immersed with their bent-off arms in the solidified foam material, while the brackets project with their cross bar from the foam material.
