Fireproof hole plug assembly
The present invention provides fire protection for pole access points and pole interiors. In accordance with preferred embodiments, the present invention provides a fireproof hole plug assembly which includes an intumescent gasket and a securing fireproof hole plug. According to further preferred embodiments, the intumescent gasket of the present invention is preferably cut to fit the fireproof hole plug and positioned to act as a barrier between the access point and external heat sources.
1. An improved fireproof hole plug assembly for protecting a pole which includes a pole wall and an access point for accessing the interior of the pole, wherein the fireproof hole plug assembly comprises:
a main body, wherein the main body comprises an inner surface and an outer surface; wherein the main body has a first circumference;
a plurality of legs, wherein each of the plurality of legs comprises a leg main body, a retaining surface and a leg head; wherein the leg head is offset from the main axis of the leg main body; and
an intumescent gasket, wherein the intumescent gasket has a second circumference;
wherein the intumescent gasket comprises a plurality of leg slits configured and positioned to receive each of the plurality of legs.
2. The fireproof hole plug assembly of claim 1 , wherein the intumescent gasket is positioned between the main body and the pole wall.
3. The fireproof hole plug assembly of claim 2 , wherein the second circumference is greater than the first circumference.
4. The fireproof hole plug assembly of claim 2 , wherein the second circumference is equal to the first circumference.
5. The fireproof hole plug assembly of claim 3 , wherein each of the plurality of leg slits are configured to allow one of the plurality of legs to pass through the intumescent gasket.
6. The fireproof hole plug assembly of claim 5 , wherein each of the plurality of leg slits is configured to allow one of the plurality of legs to pass through the intumescent gasket and through the pole wall.
7. The fireproof hole plug assembly of claim 6 , wherein the pole wall comprises a curved outer surface; wherein the main body comprises a curved surface which is curved to approximate the curve of the pole wall.
8. The fireproof hole plug assembly of claim 6 , wherein the pole wall comprises a flat outer surface; wherein the main body comprises a flat surface.
9. The fireproof hole plug assembly of claim 7 , wherein the intumescent gasket has a diameter greater than 1 inch.
10. The fireproof hole plug assembly of claim 9 , wherein the main body is comprised of material selected from the group of materials comprising: stainless steel, galvanized steel, and zinc.
11. The fireproof hole plug assembly of claim 10 , wherein the main body comprises a layer of intumescent paint.
12. The fireproof hole plug assembly of claim 11 , wherein the plurality of legs comprises a first leg; wherein the first leg comprises a proximal end connected to the main body and a distal end; wherein the first leg is formed of a flexible material; wherein the first leg is biased to bend inwardly in response to pressure applied to its distal end.
13. The fireproof hole plug assembly of claim 12 , wherein the distal end of first leg is formed at an angle to a main axis of the first leg.
14. The fireproof hole plug assembly of claim 13 , wherein the intumescent gasket extends beyond the first circumference of the main body.
