Abstract

Various embodiments of the present disclosure provide a joint edge assembly and method of positioning and installing joint edge assembly for adjacent concrete slabs. The method includes positioning the joint edge assembly in an offset position from the joint. The method of various embodiments also includes using a plurality of height adjusters or plates fixed to the slab engagement surface of the one of the joint edge members to adjust or assist in adjusting the height of the joint edge assembly relative to the formwork and relative to the plane of the top surfaces of the concrete slabs.

First claim

The invention is claimed as follows:

1. A method of forming a joint between a first concrete slab and a second concrete slab using a joint edge assembly, the joint edge assembly including a first elongated joint edge member, a second elongated joint edge member, a plurality of first anchors extending from the first elongated joint edge member into the first concrete slab, and a plurality of second anchors extending from the second elongated joint edge member into the second concrete slab, said method comprising:
(a) positioning the first joint edge member such that:
(i) a slab engagement surface of the first joint edge member extends in a first vertical or substantially vertical plane directly adjacent to a vertically extending plane in which a vertically extending side or end surface of the first concrete slab will lie such that the slab engagement surface of the first joint edge member will be adjacent to the vertically extending side or end surface of the first concrete slab after the first concrete slab is poured,
(ii) the slab engagement surface of the first joint edge member extends in the first vertical or substantially vertical plane outward relative to any vertically extending plane in which any vertically extending side or end surface of the first concrete slab will lie after the first concrete slab is poured, and
(iii) a second slab facing side of the first joint edge member extends in a second vertical or substantially vertical plane inwardly relative to a vertical or substantially vertical plane of the second concrete slab in which a vertically extending side or end surface of the second concrete slab will lie after the second concrete slab is poured; and

(b) positioning the second joint edge member such that:
(i) a first slab facing side of the second joint edge member extends in a third vertical or substantially vertical plane further inwardly relative to the vertical or substantially vertical plane of the second concrete slab in which the vertically extending side or end surface of the second concrete slab will lie after the second concrete slab is poured, and
(ii) a slab engagement surface of the second joint edge member extends in a fourth vertical or substantially vertical plane even further inwardly relative to the vertical or substantially vertical plane of the second concrete slab in which the vertically extending side or end surface of the second concrete slab will lie after the second concrete slab is poured.

2. The method of claim 1 , which includes using a plurality of connectors to connect the first and second elongated joint edge members along their lengths prior to positioning the first and second elongated joint edge members.

3. The method of claim 1 , wherein the joint edge assembly includes height adjusters fixed to the first joint edge member, and which includes:
(a) positioning first formwork fasteners through variable openings in the height adjusters and into the formwork below the first and second joint edge members,
(b) setting a height of the first and second joint edge members relative to the formwork below the first and second joint edge members, and
(c) positioning second formwork fasteners through non-variable openings in the height adjusters and into the formwork below the first and second joint edge members to fix the height of the first and second joint edge members relative to the formwork below the first and second joint edge members.

4. The method of claim 1 , wherein the joint edge assembly includes at least one height adjuster plate fixed to the first joint edge member.

5. The method of claim 4 , which includes attaching dowel pockets to the at least one height adjuster plate.

6. The method of claim 1 , wherein the joint edge assembly includes a plurality of spaced apart height adjuster plates fixed to the first joint edge member.

7. The method of claim 6 , wherein the height adjuster plates define variable openings.

8. The method of claim 1 , wherein the joint edge assembly includes a horizontally or substantially horizontally extending metal plate fixed to the first elongated joint edge member.

9. The method of claim 1 , which includes employing one or more shims to maintain the adjusted height of the joint edge assembly.

10. A method of forming a joint between a first concrete slab and a second concrete slab using a joint edge assembly, the joint edge assembly including a first elongated joint edge member, a second elongated joint edge member, a plurality of first anchors extending from the first elongated joint edge member into the first concrete slab, and a plurality of second anchors extending from the second elongated joint edge member into the second concrete slab, said method comprising:
(a) positioning the second joint edge member such that:
(i) a slab engagement surface of the second joint edge member extends in a first vertical or substantially vertical plane directly adjacent to a vertically extending plane in which a vertically extending side or end surface of the second concrete slab will lie such that the slab engagement surface of the second joint edge member will be adjacent to the vertically extending side or end surface of the second concrete slab after the second concrete slab is poured
(ii) the slab engagement surface of the second joint edge member extends in the first vertical or substantially vertical plane outward relative to any vertically extending plane in which any vertically extending side or end surface of the second concrete slab will lie after the second concrete slab is poured, and
(iii) a first slab facing side of the second joint edge member extends in a second vertical or substantially vertical plane inwardly relative to a vertical or substantially vertical plane of the first concrete slab in which the vertically extending side or end surface of the first concrete slab will lie after the first concrete slab is poured; and

(b) positioning the first joint edge member such that:
(i) a second slab facing side of the first joint edge member extends in a third vertical or substantially vertical plane further inwardly relative to the vertical or substantially vertical plane of the first concrete slab in which the vertically extending side or end surface of the first concrete slab will lie after the first concrete slab is poured, and
(ii) a slab engagement surface of the first joint edge member extends in a fourth vertical or substantially vertical plane even further inwardly relative to the vertical or substantially vertical plane of the first concrete slab in which the vertically extending side or end surface of the first concrete slab will lie after the first concrete slab is poured.

11. The method of claim 10 , which includes using a plurality of connectors to connect the first and second elongated joint edge members along their lengths prior to positioning the first and second elongated joint edge members.

12. The method of claim 10 , wherein the joint edge assembly includes height adjusters fixed to the second joint edge member, and which includes:
(a) positioning first formwork fasteners through variable openings in the height adjusters and into the formwork below the first and second joint edge members,
(b) setting a height of the first and second joint edge members relative to the formwork below the first and second joint edge members, and
(c) positioning second formwork fasteners through non-variable openings in the height adjusters and into the formwork below the first and second joint edge members to fix the height of the first and second joint edge members relative to the formwork below the first and second joint edge members.
