Duct, preferably a ventilating duct and method of assembly of a duct, preferably the ventilating duct

摘要

especially the ventilation channel has, interconnected, tin elements (1 and 2). the shape of the element (1), in a plane perpendicular to the direction of movement is similar, preferably same to shape element (2). especially the ventilation channel, made up of two, especially the same elements (1 and 2) facilitates the production.connection, by zasuniu0119cie behind of ksztau0142towych on element (1) with the coupling element (2), ksztau0142towymi on feasible without tools or connection through riveting or rolling made using simple hand tools, allows for the installation in the construction. the construction site are transported in disassembled state, with little space during transport.fixing element (1) in a displaced position relative to the element (2) can be combined with each other in series channels avoiding use of additional connectors.
