Abstract: Reinforced masonry construction including walls or slabs comprising elongated panels having permanent wall or slab forms (or skins) which are spaced a predetermined distance apart by unique ties which also serve as a web member or a component thereof resulting between reinforcing bars and/or structural shapes acting as the chords of a truss. The panels are preferably precast from high strength structural grade cellular concrete reinforced with a novel truss. The longitudinal edges of adjacent panels are in contiguous engagement, opposed panels being connected by a tie having portions which interfit the contiguous panels for positioning same. The ties are arranged in vertical or horizontal alignment and reinforcing rods, in unitary or multi-part arrangement, extend through the ties from one end to the other transversely of the wall or slab to provide or supplement a structural section.
