<p>An apparatus for fixating and elevating an interconnected rebar lattice having individual longitudinal and transverse rebar intersections for use as a support for poured concrete in highway and other construction. The apparatus including a holding portion (12) having an open-ended recess (16) with two opposing walls (18) being generally U-shaped. The recess has a longitudinal axis and is sized and shaped to receive a longitudinal rod. An arc-shaped portion (20) extends laterally outward from each opposing wall and perpendicular to the longitudinal axis of the recess. The arc-shaped portion has a transverse axis and is sized and shaped to receive a longitudinal rod. The arc-shaped portion includes a recess (22) and opposing walls (24) with each wall having a snap-type lock (26, 36). A locking member (28) has a generally arc-shaped portion (32) and includes a snap-type lock (30) for attaching to the arc-shaped portions (20) and engaging with the snap-type lock (26, 36) of the arc-shaped portions (20). A leg portion (14) extends downwardly from the holding portion (12) and is integrally attached to a base (42).</p> |
