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 second leg having a second greater height than the first leg and connected to the first leg;
- and
- (d) a second foot connected to the second leg,
- 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.
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 second leg having a second greater height than the first leg and connected to the first leg;
- (d) a second foot connected to the second leg;
- and
- (e) a stabilizer connected to the first leg, the first foot, the second leg, and the second foot,
- 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.
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;
- and
- (f) a second toe connected to the first foot;
- 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.
A joint assembly for a joint between a first concrete slab and a second concrete slab, said joint assembly comprising:
- a first elongated joint edge member including a slab engagement surface configured to be positioned directly adjacent to a vertically extending plane in which a vertically extending end surface of a first concrete slab will lie;
- a second separate elongated joint edge member;
- a plurality of connectors that connect the first and second elongated joint edge members along their length during installation;
- a plurality of first anchors that extend from the first elongated joint edge member into a region where concrete of the first concrete slab will be poured such that, upon hardening of the first concrete slab, the first anchors are cast within the first concrete slab;
- a plurality of second anchors that extend from the second elongated joint edge member into a region where concrete of a second concrete slab will be poured such that, upon hardening of the second concrete slab, the second anchors are cast within the second concrete slab;
- and
- an elongated attacher including a body defining a series of slots configured to receive pockets, said body having:
- (a) a first slab engagement surface configured to be positioned inwardly of the substantially vertically extending plane in which the substantially vertically extending end surface of the first concrete slab will lie, and
- (b) a second slab engagement surface configured to be positioned in substantially the same substantially vertically extending plane in which the substantially vertically extending end surface of the first concrete slab will lie.
