Abstract

A concrete anchor and a method of using such an anchor is disclosed where the anchor comprises a tube having a mounting flange and a retention feature. The tube is encased in concrete and a bar is subsequently secured within the tube such that an exposed end of the bar can be encased in a subsequent concrete formation. In one embodiment a plurality of concrete anchors are secured together by one or more rails forming a set.

Claims

1. A set of concrete anchors comprising:

a first rail;

a plurality of concrete anchors attached to and spaced along the first rail, each of the plurality of concrete anchors comprising;

an elongated tube having a receiving end and a distal end opposite the receiving end and an outer surface extending between the receiving end and the distal end wherein the distal end is closed;

a mounting flange disposed proximate the receiving end; and

at least one retention feature disposed on the elongated tube.

2. The set of concrete anchors of claim 1 wherein each of the plurality of concrete anchors further comprises a second rail spaced apart from and parallel to the first rail.

3. The set of concrete anchors of claim 1 wherein the retention feature is disposed on the distal end.

4. The set of concrete anchors of claim 1 wherein the retention feature is disposed on the elongated tube between the receiving end and the distal end.

5. The set of concrete anchors of claim 1 wherein the retention feature comprises the tube having a first outside dimension proximate the receiving end that is smaller than a second outside dimension proximate the distal end.

6. The set of concrete anchors of claim 1 wherein there are two or more retention features disposed on the elongated tube.

7. The set of concrete anchors of claim 1 wherein the receiving end is closed with a removable plug or foil.

8. The set of concrete anchors of claim 1 having a mounting feature configured to be securable to a rail.

9. The set of concrete anchors of claim 1 wherein a cross-section of the elongated tube is generally circular.

10. The set of concrete anchors of claim 1 wherein a cross-section of the elongated tube is generally rectangular.
