Quick-connector for rebar to concrete dowels
First Claim
1. A quick connector for the terminal fastening of a penetrating rebar (7) to a perpendicularly oriented concrete dowel (2), the connector comprising a wire loop (1) including a deflected wire segment of a length (L) at least partially made of a resiliently elastic metal, wherein the wire loop (1) is at an angle (α
- ) of approximately between 90°
to 180°
relative to a primary turning arc (3), the primary turning arc (3) being adapted to receive the concrete dowel and having arms (5, 5′
) that are mirror-symmetrical to an angle-bisecting plane (4), wherein each arm (5, 5′
) forms a secondary turning arc (6, 6′
), at an angle (β
) of approximately 180°
, transverse to the primary turning arc (3), for unilaterally receiving a rebar (7) arranged essentially perpendicular to the concrete dowel (2) wherein each arm (5, 5′
) carries at its end a clippable hook (8, 8′
), transversely angled to the primary turning arc (3), the hook being adapted to force-fittingly rest in a radial external surface zone (9) of a terminal radial expansion of the concrete dowel (2), and wherein each arm (5, 5′
) includes a tertiary turning arc (11, 11′
) arranged between the secondary turning arc (6, 6′
) and the clippable hook (8, 8′
) at an angle (γ
) between 90°
to 270° and
each arm (5, 5′
) includes a quaternary turning arc (12, 12′
) that is parallel to the secondary turning arc (6, 6′
) at an angle (δ
) between 90°
to 180°
, and arranged between the tertiary turning arc (11, 11′
) and the clippable hook (8, 8′
).

Abstract
A quick-connector for terminal fastening of a penetrating rebar (7) to a perpendicularly oriented concrete dowel (2), the connector comprising a wire clip (1) having a deflected segment of wire of the length (L) at least partially made of resilient-elastic metal, wherein the wire clip (1) includes, with respect to a primary turning arc (3), arms (5, 5′) that are mirror-symmetrical to an angle-bisecting plane (4), wherein each arm (5, 5′) forms a deflected secondary turning arc (6, 6′) transverse to the primary turning arc (3) and a clippable hook (8, 8′) that rests force-lockingly into a radial external surface zone (9), of a terminal radial expansion (1), of the concrete dowel (2).
