FIELD: construction. ^ SUBSTANCE: invention relates to construction technologies and may be used in gas removal channel structures of smoke chimney, and particularly, in channel structures made of composite materials. The technical result of the invention is the simplification of gas removal channel design, wider operational characteristics and improvement of maintainability. Gas removal channel of smoke chimney consists of the panels with side edges directed outside. The side edges are arranged as annular bands along chimney height. The side edges are made of composite material based on the manufactured reinforcing fiber and polymer binder. The gas removal channel also consists of mechanical fastening elements for panels fixing to each other. The channel panels are made curvilinear or flat. The flat panels are rigid, each of them is provided with additional jointing end edges directed perpendicular and outside until it joins jointing side edges. Thus, closed trough-shaped structure is formed. Mechanical fasteners are located in holes of all edges. In addition, each panel is provided with, at least, one stiffening rib being outside or inside between the jointing end edges and represented with glass-fiber-reinforced moulding profile from composite material. ^ EFFECT: simplification of gas removal channel design, wider operational characteristics and improvement of maintainability. ^ 24 cl, 3 dwg |
