Abstract

A system of attaching and aligning both parallel and transverse bars for supporting a concrete matrix includes a plurality of substantially identical molded plastic clips for alternatively attaching and holding two parallel reinforcing bars of equal diameter or two transverse reinforcing bars of equal diameter.

Claims

1. A system of attaching and aligning both parallel and transverse reinforcing bars for supporting a concrete matrix, comprising:

a plurality of substantially identical molded plastic clips for alternatively attaching and holding two parallel reinforcing bars of equal diameter or two transverse reinforcing bars of equal diameter, each clip including;

two transverse supports;

two pairs of lower legs extending downwardly from the two transverse supports, the two pairs of lower legs defining spaced lower seats of a first diameter, each pair of lower legs having a lower gap defining an opening from lower ends of the lower legs to the lower seats;

two pairs of upper legs extending upwardly from the two transverse supports, the two pairs of upper legs defining spaced upper longitudinal seats parallel to the lower seats and having diameters equal to the first diameter of the lower seats;

two longitudinal supports extending between the two pairs of upper legs, the two longitudinal supports joining upper ends of one pair of upper legs to upper ends of the other pair of upper legs, the two longitudinal supports having an upper gap therebetween defining an opening to the upper longitudinal seats, the upper gap being larger than the lower gap when each clip is in an unstressed position; and

two spaced upper transverse seats defined on lower surfaces of the two longitudinal supports, the upper transverse seats being transverse to the lower seats and having diameters equal to the first diameter of the lower seats.

2. The system of claim 1, wherein:

each pair of lower legs have outwardly flared lower ends.

3. The system of claim 1, wherein:

each of the clips has a gauge corresponding to a gauge of the reinforcing bars receivable its seats; and

each clip has a color corresponding to and indicating the gauge of the clip.

4. The system of claim 1, wherein:

the lower legs of each clip are operatively flexible to receive a first reinforcing bar of the first diameter in the lower seats; and

the upper legs of each clip are operatively flexible to receive a second reinforcing bar of the first diameter in the upper longitudinal seats.

5. The system of claim 1, wherein:

each clip is operative to receive a reinforcing bar of the first diameter in the upper transverse seats without flexing of the clip.

8. The system of claim 1, wherein:

each clip is operatively flexible to receive the first reinforcing bar in the first seat; and

each clip is operatively flexible to receive the second reinforcing bar in the second seat.

9. The system of claim 1, wherein:

each clip is operative to receive a reinforcing bar in the third seat without flexing of the clip.

6. A system for attaching and aligning both parallel and transverse reinforcing bars for supporting a concrete matrix, comprising:

a plurality of substantially identical molded plastic clips, each clip having first and second parallel seats of equal size for holding two reinforcement bars of equal size in a parallel orientation relative to each other, and each clip having a third seat oriented perpendicular to said first and second seats, said third seat being equal in size to said first seat so that said first and third seats may hold two reinforcement bars of equal size in a transverse orientation relative to each other, said first seat being defined by a pair of fingers having outwardly flared guides on lower ends of the fingers, each clip having a lower gap defined between the fingers and through which a first reinforcement bar must be pressed to engage the first seat, and each clip having an upper gap through which a second reinforcement bar must be pressed to reach the second seat, the upper gap being larger than the lower gap when each clip is in an unstressed position.

7. The system of claim 6, wherein:

each of the clips has a gauge corresponding to a gauge of the reinforcing bars receivable its seats; and

each clip has a color corresponding to and indicating the gauge of the clip.
