Abstract
Abstract A wall structure and a method for producing the wall structure. The wall ucture is comprised of substantially standardized building elements which, one preferred embodiment, interlocks with adjacent elements along both the top and bottom and the vertical side surfaces. The surfaces of the building elements forming the interior and exterior surfaces of the finished wall are preferably reinforced along one such surface thereof. During the formation of the wall structure, horizontally and vertically aligned grooves are provided in the completed wall to facilitate the location at which severing should occur as well as to facilitate the severing of the reinforcing members to permit selected sections of the wall to be simply, readily and inexpensively removed. In one embodiment, the reinforcing members may be steel plates while in another alternative embodiment, the reinforcing members may be comprised of horizontally and vertically oriented elongated reinforcing rods. In embodiments where reinforcing elements are provided along the interior and exterior wall surfaces, anchor members may be employed for securing the reinforcing members along the interior surface to those along the exterior surface of the wall. Similar members may be employed to secure the reinforcing plates. The individual building elements may either have smooth engaging surfaces or interlocking engaging surfaces. The method of forming the wall comprises forming alternating building elements within the frame at spaced intervals therealong and then forming the remaining building elements at the regions between the previously formed building elements, said frame provided with means for defining the guide grooves along which enforcing members may be severed. Upon completion of the wall, the grooves may either be left uncovered, exposing the reinforcing members therein or alternatively they may be filled with construction material of lesser or weaker strength than the basic construction material, which is preferably concrete.
