Abstract

Methods and systems for plugging a hole are described. A plug may comprise a substantially tubular member having a proximal end and a distal end interconnected by a side wall, the side wall having an inward facing surface and an outward facing surface, at least the outward facing surface being substantially conformable, an adhesive disposed on the outward facing surface, a fire-resistant ring disposed substantially at one of the ends of the tubular member, and a thread disposed along the inward facing surface, the thread adapted to receive a cover.

Claims

1. A plug, comprising:

a substantially tubular member having a proximal end and a distal end interconnected by a side wall, the side all having an inward facing surface and an outward facing surface, at least the outward facing surface being substantially conformable;

an adhesive disposed on the outward facing surface;

a fire-resistant ring disposed substantially at one of the ends of the tubular member; and

a thread disposed along the inward facing surface, the thread adapted to receive a cover.

2. The plug of claim 1, wherein the ring comprises a fire-retardant sealant.

3. The plug of claim 1, wherein the tubular member comprises an elastomeric material.

4. The plug of claim 1, wherein the tubular member comprises a compliant material.

5. The plug of claim 1, wherein the adhesive is a microencapsulated adhesive.

6. The plug of claim 1, further comprising a peel-away layer disposed on the adhesive.

7. The plug of claim 1, wherein the adhesive is a time delay adhesive.

8. A kit for plugging a hole in a floor, the kit comprising:

a plug, comprising;

a substantially tubular member having a proximal end and a distal end interconnected by a side wall, the side wall having an inward facing surface and an outward facing surface, at least the outward facing surface being substantially conformable;

an adhesive disposed on the outward facing surface;

a fire-resistant ring disposed substantially at one of the ends of the tubular member; and

a thread disposed along the inward facing surface, the thread adapted to receive a cover;

and

a cover having a top and a bottom, the bottom adapted to mate with the thread.

9. The kit of claim 8, wherein the top is substantially elastomeric.

10. The kit of claim 8, wherein the top is substantially rigid.

11. The kit of claim 8, wherein the cover is adapted to be substantially flush with a surface of a floor surface when the bottom is mated to the thread and the plug is positioned in a hole in the floor.

12. The kit of claim 8, wherein the cover comprises a nut disposed on the top.

13. The kit of claim 8, wherein the cover comprises a fastener disposed on the top.

14. The kit of claim 8, wherein the plug is adapted to expand as the bottom is mated to the thread.

15. The kit of claim 8, wherein the ring comprises a fire-retardant sealant.

16. The kit of claim 8, wherein the tubular member comprises an elastomeric material.

17. The kit of claim 8, wherein the tubular member comprises a compliant material.

18. The kit of claim 8, wherein the adhesive is a microencapsulated adhesive.

19. The kit of claim 8, further comprising a peel-away layer disposed on the adhesive.

20. The kit of claim 8, wherein the adhesive is a time delay adhesive.
