Abstract
Improved grips for retaining plural concrete reinforcing bars in a selected association are disclosed. The grips include a base portion and a retention portion including engageable structures establishing first and second spaced opposing pairs of clamping formations. Each of the plural reinforcing bars in the association is positively gripped along a length thereof between the clamping formations. Grip embodiments for parallel and right angle reinforcing bar associations are disclosed.
Claims20
A grip for retaining plural concrete reinforcing bars in a selected association comprising:
- a base portion including plural mating structures spaced thereabout and configured to receive the plural concrete reinforcing bars thereat in a selected association, said mating structures each including either multiple graduated engagements or a catch;
- and
- a retention portion including plural matable structures spaced thereabout each configured to engage a different one of said mating structures of said base portion, said matable structures each including one of multiple graduated engagements and a catch not found at an opposite one of said mating structures of said base portion;
- each of said plural mating structures of said base portion variably positionable relative to and lockable with a different one of said plural matable structures of said retention portion to establish a clamping formation by selective engagement along said multiple graduated engagements with said catch so that each of the plural reinforcing bars in the association is positively gripped along a length thereof between said clamping formations.
The grip of 4 wherein each of said catches include a projection extending into said channel, said projections configured to permit movement of said graduated engagements of said appendages thereby in one direction and restrict movement of said graduated engagements of said appendages thereby in an opposite direction to thus lock said clamping formations.
A grip for retaining plural concrete reinforcing bars in a selected association comprising:
- a base portion configured to receive the plural concrete reinforcing bars thereat in a selected association and including at least three tongue structures spaced thereabout each including multiple engagements therealong;
- and
- a retention portion including at least three openings spaced thereabout each configured to receive a different one of said tongue structures of said base portion, said openings each having a catch positioned therein;
- whereby each of said tongue structures of said base portion is variably positionable relative to and lockable at one of said openings of said retention portion by selective receipt in one of said multiple engagements of said catch.
The grip of claim of 12 wherein said planar surface of said base portion is defined by first and second flanges extending from opposite elongated sides of said contoured reinforcing bar receiving structure and each having at least one of said tongue structures projecting therefrom.
The grip of claim of 14 wherein said retention portion has a plurality of channels at an outer periphery thereof, each of said channels defined in part by one of said catches and having one of said opening therethrough.
A grip for retaining plural concrete reinforcing bars in a selected association comprising:
- a base portion configured to receive the plural concrete reinforcing bars thereat in a selected association and including first and second spaced opposing pairs of tongue structures;
- and
- a retention portion including at least a first elongated contoured reinforcing bar receiving structure and first and second spaced opposing pairs of openings, each of said openings configured to receive a different one of said tongue structures of said base portion, said openings each having a catch positioned therein;
- said tongue structures of said base portion variably positionable relative to and lockable at said openings of said retention portion by selective engagement of said catches along said tongue structures to establish a first and second spaced opposing pairs of clamping formations so that each of the plural reinforcing bars in the association is positively gripped along a length thereof between said clamping formations.
