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.
Claims1
A reinforcing member for connecting portions of contiguous structural parts comprising a prismatic body of synthetic foam having an isoceles trapezoidal cross-section, and reinforcing irons each of a U-shaped configuration and having an arch extending at right angles from the widest face of said body and the legs of each iron being bent and embedded in said body in proximity to the narrowest face of said body.
