Complex for protection of exhaust devices of gas discharge ducts of low-rise dwelling houses additionally has additional volumetric-three dimensional constructions each of which consists of flat screens and fixation units, at that each of additional volumetric-spatial constructions is made or continuous, or mostly of linear in shape structural elements placed in horizontal or vertical direction with gap one with respect to another, those additional screens are installed/placed mostly normally to direction between high-rise building and protected ventilation shaft with fixation of those screens to surface of roof, better without gap, side faces of each of additional screens are placed mostly vertically, those side faces are made either same in height, or different, upper face of each of additional screens is placed either horizontally, or in parallel to plane of roof with sharp bend in place of bend of ridge roof, or at same or different angles to it with respect to the place of bend of roof, additional screens are installed/placed with carrying-out of side walls out of boundaries of nearest side of ventilation shaft, those side faces of screen are placed mostly at different distances from end faces of nearest side of ventilation shaft at all possible variants of structural realization of screen, at that at use of two or more screens those screens are installed either at one side with respect to ventilation shaft in such way that the ventilation shaft is placed between nearest to it screen and wall of high-rise building, or at both sides with respect to ventilation shaft, those screens are installed either at same distance from nearest to those sides of ventilation shaft and to each other, or at different, at use of two or more screens with same lengths and geometric shape those are installed either with placement of side faces in one plane parallel to façade side of building, or with shift one with respect to another with respect to the façade side of the house. |
