Prefabricated tall industrial chimney - has vertical reinforcing element in ducts passing through reinforced concrete sections

摘要

The high-rise structure, esp. industrial chimney, can be quickly prefabricated and erected, and is durable. It is made up from reinforced pieces (7), with three or more through-passage ducts (8) on the periphery, in their sidewall. These contain a vertical reinforcing element (11) with cement mortar cast in. A reinforcing ring can be inlaid between the top and bottom parts, connected to both by the vertical reinforcing element, and also to three or more reinforcing ribs by tensile strips in holes (4) in these. Ribs can be assembled from prefabricated reinforced-concrete sections, of the same height as the chimney pieces.
