Inert mass of concrete with may be integrated as a seat of expandable, axially projecting elements of washing machines basin

摘要

The concrete inertia mass has the shape of a ring (1) and strainers (3) partly cast in concrete for holding the axially jutting two-end tub (7) adapters (6). The ends of the adapter (6) are spread by a final wood screw (8) which at the same time fit to the internal slant surface of the receiving funnel-shaped bedding (5) between the strap (3B) of the strainer (3) and the coat surface of the ring (1), thus connecting the ring (1) to the tub (7).
