DEVICE FOR SCATTERING POLLUTANTS DISCHARGED TO ATMOSPHERE FROM BUILDINGS Russian patent published in 1994 - IPC

FIELD: structural engineering. SUBSTANCE: cowl with a curvilinear surface is positioned outside the building and is made from separate members each of which is vertically fastened at the building corners through its entire height. The upper part of the member relative to the building is made discharging along a parabola. The lower part has two bending lines between which the member surface is convex and behind them changes to a concave one. The upper and lower parts have a smooth transition between each other. Each member is fastened to the building in the upper part by rigid links, and in the lower part - by plunger and telescopic links. The members are pivotally connected to the links. Each removable member which number is equal to the number of outer walls of the building has a central flat section, two side and an upper ring curvilinear sections. The removable members are vertically mounted through the entire height and width of the building ahead of the outer wall matching each member at a distance to the opposite wall equal 2.6-2.0 of the building height. EFFECT: improved structure. 2 dwg
