Abstract
anchor assembly (10) for anchoring a riser pipe in a floor structure comprising a plate (12) having an upper face (14) and a lower face (16) oppositely disposed from one another with an aperture extending through the plate (12). A sleeve is attached to the plate (12) that extends through the aperture and defines a bore (22) oriented transversely to the plate (12). The sleeve includes an upper sleeve portion (24) with a sleeve top (26) projecting outwardly from the upper face (14) of the plate (12) and a lower sleeve portion (28) with a sleeve bottom (30) projecting outwardly from the lower face (16) of the plate (12). A plurality of collars (36) extend through the plate (12), each having internal screw threads (38), and a plurality of studs (32) extend from the lower face (16) of the plate (12). This anchor assembly is an improvement over riser clamps that must be secured to an adjacent shear wall and depend on friction, becoming less effective with repeated thermal expansion cycles of the riser.
