Abstract: A construction member for building inner and/or bearing walls and the like includes a pair of semi-panels arranged spaced apart in opposed specular relation, the panels comprising plane bodies forming faces of a building structure, integral connecting elements protruding from the bodies having opposed outer ends spaced at a predetermined distance apart, and a connecting spacer extending between the bodies and being interconnected with the connecting elements. One of the connecting elements and the opposite ends of the spacer is substantially U-shaped with parallel inner surfaces, and the other of the connecting elements and the opposite ends being flat with parallel outer surfaces so as to facilitate an interdigitated interconnection of the spacer and the panels.
