Tubular sleeve insert for creating a void in precast concrete

Abstract

An insert is provided for forming a void in precast concrete that includes a tube defined by a wall and having a plurality of formed, longitudinally spaced-apart ribs that project radially outwardly from an outer surface of the wall. A plurality of corresponding recesses are defined in an interior surface of the wall. A plurality of score lines are positioned between the ribs so that the tube may be adjusted in length to meet the particular requirements associated with a specific design of precast concrete. At least one removable cap is positioned in an open end of the tube so as to prevent concrete from entering the tube during casting. A method for forming a void within a precast concrete structure is also provided in which the tubular sleeve assembly is positioned within a form containing uncured concrete, and one or more of the score lines are cut so as to adjust the length of the tube.

Dependencies are inferred from the claim text.
