Abstract
The fireplace and chimney is provided made of specially formed stacked modular concrete units laid with several modular concrete masonry units in horizontal masonry courses, and specifically designed so a traditional clay flue liner may be inserted into the modular chimney as it is being erected. The sections making up the fireplace and chimney are the firebox, the damper level, the structural shelf level, the tapered smoke chamber level, and the chimney to form a naturally drafted masonry fireplace assembly.
Claims10
A modular fireplace and chimney having multiple sections including a firebox, a damper level, a structural shelf level, a tapered smoke chamber level and a chimney comprising:
- (a) firebox having several vertical courses of formed pre-cast concrete masonry units forming a pair of sides and a back,
- (b) a damper level including a damper and at least one reinforced concrete lintel situated horizontally on said firebox sides to bridge across the top of said firebox opening, thereby providing a bearing surface for the front damper flange and additional masonry courses;
- (c) a structural shelf level comprising a generally rectangular reinforced concrete shelf with hole there through to allow the passage of flue gasses from said firebox into said smoke chamber and chimney above said shelf level, and to provide structural support for the overlying chimney courses;
- (d) a tapered smoke chamber level having a tapered smoke chamber, and
- (e) a chimney comprising a plurality of concrete masonry chimney members, with at least one masonry chimney member per masonry course, said masonry courses forming a structural masonry chimney shaft, bearing on the flat surface of said reinforced concrete shelf and a chimney flue liner.
