Patent Images
1. A rebar fastener comprising:
- a first clamp piece, the first clamp piece including (i) a first clamp adapted to be secured around a first piece of concrete rebar and (ii) a unitarily formed opening;
a second clamp piece, the second clamp piece including (i) a second clamp adapted to secured around a second piece of concrete rebar and (ii) a unitarily formed male appendage extending therefrom, the male appendage having a longitudinal axis;
wherein the male appendage is connected to the opening permitting pivotally movement of the first clamp piece relative to the second clamp piece about the longitudinal axis.

Abstract
A fastener for joining two pieces of rebar together in a rebar grid used to reinforce subsequently poured concrete is described. The fasteners include two clamp pieces that in certain embodiments completely wrap around a piece of rebar and are tightly secured thereto. Further, each clamp piece can swivel or rotate up to 360 degrees relative to the other clamp piece such that two rebar pieces intersecting at any angle can be coupled together.

19. A method for manufacturing a reinforced concrete structure comprising:
-
forming a plurality of pieces of rebar into a rebar grid by coupling the various pieces of the plurality of rebar pieces together at intersections thereof of any angle using a rebar fastener comprising a first clamp and a second clamp wherein the first and second clamps are rotatably coupled to each other to permit at least 180 degrees of rotation of the first clamp relative to the second clamp;
building a mold about the rebar grid; and
pouring concrete into the mold. - View Dependent Claims (20)
