Abstract

A quick release tie includes an elongated strap having retainer plates removably connected to the opposing ends of the strap. Each retainer plate includes a cylindrical body portion which extends through an aperture in a form panel, a generally flat panel affixed to an outer end of the body portion to prevent movement of the form panel outwardly off of the retainer plate, and a conical inner end tapering to a smaller diameter at the inner end of the body portion. The body portion inner end is interiorly threaded, and selectively engages exterior threads on the opposing ends of the strap to permit selective removal of the retainer plates. A socket formed in an outer surface of the retainer plate panel permits engagement of a tool for rotating the retainer plate so as to engage or disengage the retainer plate from the strap ends. A retainer cup is provided which includes a hollow generally cylindrical wall which tapers from an outer end towards an inner end in a conical shape matching the conical portion of the retainer plate. A projecting flange on the ends of each strap prevents the retainer cup from moving inwardly along the strap, such that the outer end of the retainer cup retains the form panel in engagement with the inner surface of the retainer plate panel.

Claims

1. A tie for interlocking a pair of spaced apart form panels, comprising:

an elongated strap having first and second opposing outer ends;

first means selectively and removably connected to said first end for retaining a first form panel from moving outwardly away from the strap first end; and

second means selectively removably connected to said strap second end for retaining

a second form panel from moving outwardly away from the strap second end;

said first means for retaining a first form panel from moving outwardly including;

an elongated body portion having first and second ends;

means on the body portion first end for removably connecting the body portion to the first end of the strap; and

a generally flat retainer panel mounted on the body portion second end, oriented generally orthogonally to a longitudinal axis of the body portion;

said retainer panel including an inner surface attached to the body portion, and an opposing outer surface;

said retainer panel including means for receiving and engaging a tool, for rotating the panel and body portion about the longitudinal axis of the body portion;

said means for receiving and engaging a tool including a socket formed in the outer surface and aligned coaxial with the body portion longitudinal axis.

2. The tie of claim 1, wherein said body portion is generally cylindrical.

3. The tie of claim 2 wherein said body portion includes a conical portion at the first end which tapers to a smaller diameter at the first end.

4. The tie of claim 2, wherein said means for selectively removably connecting said body portion includes an interiorly threaded aperture in the first end of said body portion, and corresponding exterior threads on the strap first end.

5. The tie of claim 1, further comprising means removably connected to said strap first end for preventing movement of the first form panel inwardly along said strap away from said first means for retaining the form panel from moving outwardly.

6. A tie for interlocking a pair of spaced apart form panels, comprising:

an elongated strap having first and second opposing outer ends;

first means selectively and removably connected to said first end for retaining a first form panel from moving outwardly away from the strap first end;

second means selectively removably connected to said strap second end for retaining a second form panel from moving outwardly away from the strap second end;

said means for preventing movement of the first form panel inwardly including;

a hollow retainer cup with a generally cylindrical wall and first and second ends, said cup having an inner diameter greater than an outer diameter of the strap first end with said strap first end journaled through said cup, and

stop means on said strap for preventing longitudinal movement of said cup inwardly beyond a predetermined position; and

means removably connected to said strap first end for preventing movement of the first form panel inwardly along said strap away from said first means for retaining the form panel from moving outwardly.

7. The tie of claim 6, wherein said stop means includes an annular flange projecting radially outwardly from said strap.

8. The tie of claim 6, wherein said retainer cup includes an annular lip projecting radially outwardly from the second end of said cup wall.

9. The tie of claim 6, wherein said cup wall is slightly conical, tapering to a smaller diameter from the second end to the first end, said first end in contact with said stop means.

10. A tie for interlocking a pair of spaced apart form panels, comprising:

an elongated strap having first and second opposing outer ends;

first means selectively and removably connected to said first end for retaining a first form panel from moving outwardly away from the strap first end; and

second means selectively removably connected to said strap second end for retaining a second form panel from moving outwardly away from the strap second end;

said first means for retaining a first form panel for moving outwardly including;

an elongated, generally cylindrical body portion having first and second ends;

means on the body portion first end for removably connecting the body portion to the first end of the strap; and

a generally flat retainer panel mounted on the body portion second end, oriented generally orthogonally to a longitudinal axis of the body portion;

said body portion including a conical portion at the first end which tapers to a smaller diameter at the first end;

said means for preventing movement of the first form panel inwardly including;

a hollow retainer cup with a generally cylindrical wall and first and second ends, said cup having an inner diameter greater than an outer diameter of the strap first end with said strap first end journaled through said cup, and

stop means on said strap for preventing longitudinal movement of said cup inwardly beyond a predetermined position.

11. The tie of claim 10, wherein said cup wall is slightly conical, tapering to a smaller diameter from the second end to the first end, said first end in contact with the stop means, and said cup conical shape corresponding with and engaging the conical portion of said body portion when the body portion is connected to the strap first end.
