Abstract: A method of constructing concrete reinforced structures employs a wall module which includes a plurality of spaced, thin walled tubes and a channel along the upper edge thereof within which concrete may be received to respectively form vertical and horizontal structural supports. A plurality of spaced, vertical support studs disposed on opposite sides of the tubes provide the module with sufficient compressive strength to carry the load of a floor mounted thereabove prior to filling the module with concrete. After the floor has been mounted on the wall modules, concrete is simultaneously poured into the tubes and channel of the module as well as into the space between the module and the floor to provide a continuous concrete connection between the floor and the wall of the resulting structure.
