Abstract:
A concrete slab construction in which a building ring is used to isolate the slab from a column which supports upper parts of a building. The ring is placed on a concrete pier beneath the column. Concrete may be poured to form a slab outside of the ring and also inside the cavity formed within the ring. The column may be placed directly on the pier before the ring is filled with concrete or on the concrete which is poured inside the ring. The ring may be tapered from bottom to top to enhance isolation of the column and pier from the slab. The ring may be adjustable in diameter and height and may have a fastening foot for securing the ring in place on the pier.
