Abstract

Various embodiments of the present disclosure provides a joint edge assembly and a reusable multiple position height adjuster and method of positioning and installing joint edge assembly and the reusable multiple position height adjuster for forming two adjacent concrete slabs and a joint between such adjacent concrete slabs.

First claim

The invention is claimed as follows:

1. A reusable multiple position height adjuster for supporting first and second elongated joint members of a joint edge assembly configured to form a joint between two concrete slabs, said reusable multiple position height adjuster comprising:
(a) a first leg of a first height;
(b) a first foot connected to the first leg;
(c) a first toe connected to the first foot;
(d) a second leg having a second greater height than the first leg and connected to the first leg,
(e) a second foot connected to the second leg;
(f) a second toe connected to the second foot; and
(g) a stabilizer connected to the first leg, the first foot, the first toe, the second leg, the second foot, and the second toe,
wherein the first leg, the first foot, the first toe, the second leg, the second foot, and the second toe are configured to be positioned in a first position such that the first leg extends vertically or substantially vertically, the first foot extends horizontally or substantially horizontally and supports the first and second elongated joint members, the first toe extends from the first foot upwardly or substantially upwardly and above the first foot in a direction facing away from the second leg, and the second leg extends horizontally or substantially horizontally, and
wherein the first leg, the first foot, the first toe, the second leg, the second foot, and the second toe are configured to be positioned in a second position such that the second leg extends vertically or substantially vertically, the second foot extends horizontally or substantially horizontally and supports the first and second elongated joint members, the second toe extends from the second foot upwardly or substantially upwardly and above the second foot in a direction facing away from the first leg, and the first leg extends horizontally or substantially horizontally.

2. The reusable multiple position height adjuster of claim 1 , which is made from a plastic.

3. The reusable multiple position height adjuster of claim 1 , wherein the first leg defines suitable fastener openings.

4. The reusable multiple position height adjuster of claim 1 , wherein the second leg defines suitable fastener openings.

5. A reusable multiple position height adjuster for supporting first and second elongated joint members of a joint edge assembly configured to form a joint between two concrete slabs, said reusable multiple position height adjuster comprising:
(a) a first leg of a first height;
(b) a first foot connected to the first leg;
(c) a first toe connected to the first foot;
(d) a second leg having a second greater height than the first leg and connected to the first leg;
(e) a second foot connected to the second leg;
(f) a second toe connected to the second foot; and
(g) a stabilizer connected to the first leg, the first foot, the first toe, the second leg, the second foot, and the second toe, wherein a portion of the first leg that is connected to a portion of the second leg is also connected to the stabilizer,
wherein the first leg, the first foot, the second leg, and the second foot are configured to be positioned in a first position such that the first leg extends vertically or substantially vertically, the first foot extends horizontally or substantially horizontally and supports the first and second elongated joint members, and the second leg extends horizontally or substantially horizontally, and
wherein the first leg, the first foot, the second leg, and the second foot are configured to be positioned in a second position such that the second leg extends vertically or substantially vertically, the second foot extends horizontally or substantially horizontally and supports the first and second elongated joint members, and the first leg extends horizontally or substantially horizontally.

6. The reusable multiple position height adjuster of claim 5 , which is made from a plastic.

7. The reusable multiple position height adjuster of claim 5 , wherein the first leg defines suitable fastener openings.

8. The reusable multiple position height adjuster of claim 5 , wherein the second leg defines suitable fastener openings.

9. The reusable multiple position height adjuster of claim 5 , wherein when the first leg, the first foot, the second leg, and the second foot are positioned in the first position, the first toe extends vertically or substantially vertically, and wherein when the first leg, the first foot, the second leg, and the second foot are positioned in the second position, the second toe extends vertically or substantially vertically.

10. A reusable multiple position height adjuster for supporting first and second elongated joint members of a joint edge assembly configured to form a joint between two concrete slabs, said reusable multiple position height adjuster comprising:
(a) a first leg of a first height, the first leg defining suitable fastener openings;
(b) a first foot connected to the first leg;
(c) a first toe connected to the first foot;
(d) a second leg having a second greater height than the first leg and connected to the first leg, the second leg defining suitable fastener openings;
(e) a second foot connected to the second leg;
(f) a second toe connected to the first foot; and
(g) a stabilizer connected to the first led, the first foot, the first toe, the second leg, the second foot, and the second toe,
wherein the first leg, the first foot, the second leg, and the second foot are configured to be positioned in a first position such that the first leg extends vertically or substantially vertically, the first foot extends horizontally or substantially horizontally and supports the first and second elongated joint members, the first toe extends from the first foot upwardly or substantially upwardly and above the first foot in a direction facing away from the second leg, and the second leg extends horizontally or substantially horizontally,
wherein the first leg, the first foot, the second leg, and the second foot are configured to be positioned in a second position such that the second leg extends vertically or substantially vertically, the second foot extends horizontally or substantially horizontally and supports the first and second elongated joint members, the second toe extends from the second foot upwardly or substantially upwardly and above the second foot in a direction facing away from the first leg, and the first leg extends horizontally or substantially horizontally,
wherein at least one of the suitable fastener openings of the second leg is configured to receive a fastener usable to secure the first position, and
wherein at least one of the suitable fastener openings of the first leg is configured to receive the fastener usable to secure the second position.

11. The reusable multiple position height adjuster of claim 10 , which is made from a plastic.
