Claims
- 1. A pre-fabricated and modular chimney facade system adapted to be secured to an external wall of a building structure, comprising:
- (a) a substantially vertically directed chimney stack passing external said building structure and being substantially enclosed by said chimney facade system;
- (b) a substantially vertically directed first base housing adapted to be fixedly secured to said external wall of said building structure, said first base housing having an upper substantially horizontally directed flange member extending partially internal said first base housing on one portion thereof for interface securement to another horizontally directed flange member formed on another portion f said first housing; and,
- (c) a substantially vertically directed second base housing secured to said first base housing in nested interface therewith.
- 2. The chimney facade system as recited in claim 1 where said first base housing includes a substantially vertically directed upper flange member and said second base housing includes a substantially vertically directed lower flange member offset from said first base housing upper flange member for nested interface of said upper and lower flange members.
- 3. The chimney facade system as recited in claim 2 where said second base housing is a cap member having an upper flange member extending substantially normal said vertical direction and internal a cross-sectionally closed contour of said second base housing.
- 4. The chimney facade system as recited in claim 2 where at least said second base housing includes a lower substantially horizontally directed flange member extending partially internal said second base housing for forming an interface shoulder for said upper flange member of said first base housing.
- 5. The chimney facade system as recited in claim 1 where said substantially horizontally directed flange members are substantially step shaped in contour on interfacing end sections thereof for mating engagement of said substantially horizontally directed flange members to form said first base housing into a cross-sectionally closed contour.
- 6. The chimney facade system as recited in claim 5 where said substantially horizontally directed flange members are fixedly secured each to the other at said interfacing end sections.
- 7. The chimney facade system as recited in claim 6 where said substantially horizontally directed flange members are adhesively bonded each to the other along said step shaped contoured end sections.
- 8. The chimney facade system as recited in claim 2 where at least said second base housing includes a first and second pair of sidewall members, each of said pairs of sidewall members being L-shaped in cross-sectional contour having interfacing end portions for mating engagement of said first and second pair of sidewall members.
- 9. The chimney facade system as recited in claim 8 where each of said pairs of L-shaped sidewall members is formed in one-piece formation.
- 10. The chimney facade system as recited in claim 8 where each of said first and second pair of sidewall members includes a substantially horizontally directed flange member for interface engagement with a substantially horizontally directed flange member formed on the other of said pairs of said sidewall members.
- 11. The chimney facade system as recited in claim 10 where said substantially horizontally directed flange members include step shaped end sections for mating interface each to the other.
- 12. The chimney facade system as recited in claim 8 where said pairs of L-shaped sidewall members are formed of a plastic material composition.
- 13. The chimney facade system as recited in claim 12 where said pairs of L-shaped sidewall members are molded in one-piece formation.
- 14. The chimney facade system as recited in claim 2 where at least said second base housing includes at least four sidewall members, each of said sidewall members being substantially planar in contour having interfacing end portions for mating engagement each to the other.
- 15. The chimney facade system as recited in claim 14 where each of said sidewall members is formed in one-piece formation.
- 16. The chimney facade system as recited in claim 14 where each of said sidewall members includes a substantially horizontally directed flange member for interface engagement with a substantially horizontally directed flange member formed on another of said sidewall members on respective end sections thereof.
- 17. The chimney facade system as recited in claim 16 where said substantially horizontally directed flange members include step shaped end sections for mating interface each with respect to the other.
- 18. The chimney facade system as recited in claim 14 where said sidewall members are formed of a plastic material composition.
- 19. The chimney facade system as recited in claim 18 where said sidewall members are molded in one-piece formation.
- 20. The chimney facade system as recited in claim 2 where said external wall of said building structure is a roof member.
- 21. The chimney facade system as recited in claim 20 where said first base housing is fixedly secured to said roof member.
- 22. The chimney facade system as recited in claim 21 where said first base housing includes a lower flange member extending substantially normal a vertical plane, said lower flange member being fixedly secured to said roof member.
- 23. The chimney facade system as recited in claim 21 where said roof member forms an inclined plane with respect to a horizontal plane.
- 24. The chimney facade system as recited in claim 23 where said first base housing includes:
- (a) a pair of sidewall members having a truncated rectangular contour defining a lower portion having an inclined angle substantially equal to the angle of inclination of said plane of said roof member; and,
- (b) a pair of rear and frontal wall members secured respectively to said sidewall members.
