Concrete anchor bodies and plugs
An anchor for being embedded in concrete for attachment to a fastener to support a load comprises a plug having a main body portion extending upwardly from a base portion, the plug for being attached to a form board prior to pouring of concrete, the plug having an end portion disposed a distance from the form board; and an anchor body attached to the end portion. The plug is separable from the anchor body and removable from the concrete after the concrete is cured, leaving the anchor body embedded in the concrete, the plug providing a void in the concrete after removal to provide an access opening for a threaded portion of a fastener to attach to the anchor body.
1. A plug for creating a passageway in concrete, comprising:
a) a main body portion extending upwardly from a base portion, the plug for being attached to a form board with a nail or screw prior to pouring of concrete;
b) the main body portion including a central opening for providing access into the concrete;
c) the main body including an end portion disposed a distance from the base portion, the end portion for supporting a first anchor body such that a bottom portion of the first anchor body is exposed to direct contact with the concrete; and
d) a cap for being disposed over the first anchor body.
2. The plug as in claim 1 , wherein:
a) the base portion includes an edge portion with a base opening for receiving the nail or screw; and
b) the base opening is configured to allow the nail or screw to separate from the base portion and remain attached to the form board when the form board is removed.
3. The plug as in claim 2 , wherein the base opening includes a peripheral edge portion with a circumferential slit partway into a thickness of the base portion.
4. The plug as in claim 1 , wherein:
a) the base portion includes a base opening within the central opening, the base opening for receiving the nail or screw; and
b) the base opening is configured to allow the nail or screw to separate from the base portion and remain attached to the form board when the form board is removed.
5. The plug as in claim 4 , wherein the base opening includes a peripheral edge portion with a circumferential slit partway into a thickness of the base portion.
6. The plug as in claim 1 , wherein:
a) the base portion includes a central portion disposed at a bottom portion of the central opening;
b) the central portion is for being attached to the form board with the nail or screw; and
c) the central portion is configured to separate from the central opening and remain attached to the form board when the form board is removed.
7. The plug as in claim 6 , wherein:
a) the central portion includes a thickness; and
b) the central portion includes a circular slit partway into the thickness around the base opening.
8. The plug as in claim 1 , wherein:
a) the base portion includes a base opening for receiving the nail or screw within the central opening; and
b) the base portion is configured to separate from the main body portion and remain attached to the form board when the form board is removed.
9. The plug as in claim 8 , wherein the base portion is attached to the main body portion with breakable members.
10. The plug as in claim 1 , wherein:
a) the base portion includes an edge portion with a base opening for receiving the nail or screw; and
b) the base portion is configured to separate from the main body portion and remain attached to the form board when the form board is removed.
11. The plug as in claim 10 , wherein:
a) base portion includes a thickness; and
b) the base portion includes a circumferential slit partway into the thickness adjacent a bottom portion of the main body portion.
12. The plug as in claim 1 , wherein:
a) the base portion includes a central portion removably received within the central opening;
b) the central portion includes a base opening for receiving the nail or screw.
13. The plug as in claim 1 , wherein the main body portion is separable from the concrete when the form board is removed.
14. The plug as in claim 1 , and further comprising a first anchor body supported by the end portion.
15. The plug as in claim 14 , wherein a first opening of the first anchor body is sealed by the end portion.
16. The plug as in claim 14 , and further comprising a second anchor body operably supported by the end portion.
17. The plug as in claim 16 , wherein:
a) the second anchor body includes a second threaded opening with a second diameter; and
b) the second anchor body is disposed above the first anchor body.
18. The plug as in claim 17 , wherein the cap is disposed over the second anchor body.
19. The plug as in claim 18 , wherein the cap provides a space above the second anchor body.
20. The plug as in claim 14 , wherein the first anchor body includes a threaded opening with a first diameter and a second diameter.
21. The plug as in claim 1 , wherein the end portion of the main body portion is threaded.
22. The plug as in claim 1 , wherein the base portion remains attached to the form board when the form board is removed.
23. The plug as in claim 1 , wherein:
a) the base portion includes a central portion disposed at a bottom portion of the central opening; and
b) the central portion remains attached to the form board when the form board is removed.
24. The plug as in claim 14 , wherein the cap includes a marking indicating the diameter and thread size of the first anchor body.
25. The plug as in claim 14 , wherein the end portion includes outwardly extending arms for supporting the anchor body.
26. The plug as in claim 25 , wherein:
a) partly circular members are attached to adjacent arms; and
b) the cap is threaded to the partly circular members.
