ABSTRACT:
A vertical modular construction element of cast concrete rests at its lower end on spaced feet between which at least one closed steel loop is provided for the reception of threaded reinforcing rods that interconnect a series of such construction elements disposed side-by-side, for the construction of retaining walls, etc. The closed loop depends below the construction element a distance less than the height of the feet, so that the closed loop is spaced above the ground when the element rests on the ground on its feet. The elements can be either ribbed or rectangular in cross section. If ribbed, then there is a foot at the end of each free edge of each rib and the loop is embedded in one of the feet. In any case, the loops are the lower portions of U-shaped steel rods whose legs extend up along the height of the element and are embedded in the element so as to resist horizontal forces imposed on the element.
