First and second receiver portions extend longitudinally from the respective first and second flanges beyond one of the ends for receiving a second rebar extending in a second direction substantially orthogonal to the first direction, and for urging the second rebar against the first rebar. Optionally, legs extend from or are attached to the apparatus for supporting the apparatus in an elevated position.

  • Publication number: 20040098942
    Abstract: A chair for supporting and spacing post-tension cables having a generally tapered body with an upper receiving area for securing the cables and a planar base adapted to rest on a flat support surface. The body has inner and outer surfaces that are substantially complementary to one another to allow a plurality of chairs to be stacked together. The receiving area includes posts extending upwardly between notches. The posts define passageways for guiding the cables into the notches. Detents project inwardly from the tops of the posts and fixedly retain the bars within the passageways. The chair may be formed from a resilient polymeric material.

  • Patent number: 6732484
    Abstract: A chair supports rebar or wire mesh during a concrete pour. The chair is box shaped having grooves in the side walls of different width for supporting rebar of different diameter. Notches in the edge of the grooves on opposite sides of the chair support wire mesh of different diameter. The notches are shaped so the wire mesh is snapped into the notch. Wall like braces extend across the inside of the chair and support the grooves from the opposite wall. The larger grooves are on the short sides of the chair to raise the rebar a longer distance off the underlying surface. In a preferred embodiment, the chair provides two elevations for placement of rebar, namely 2″ and 3″ above an underlying surface. Parts of the box are cut away to promote concrete movement through the chair. Slots are provided to allow air trapped in the concrete to escape from the chair.

    Abstract: A concrete reinforcing bar support including a base, a support structure extending upwardly from the base, a first clamping member affixed to the support structure and extending upwardly above a top surface of the support structure, a second clamping member affixed to the support structure and extending upwardly above a top surface of the support structure, and a third clamping member affixed to the support structure and extending upwardly above the top surface of the support structure. The second clamping member has an interior surface generally facing the interior surfaces of the first and third clamping members. The first clamping member is separated by a space from the third clamping member. Ribs extend inwardly from the interior surfaces of each of the clamping members so as to compressively contact a reinforcing bar placed interior of the clamping members. The support structure has a generally H-shaped cross-section in a plane parallel to said base.
