FIELD: construction.
SUBSTANCE: invention relates to construction and is intended for installation of wind tunnel to prevent accumulation of snow on roofs of buildings. Universal device for installation of a wind tunnel includes a two-axis hinge consisting of two half-hinges connected by a link. On each of two axles three bushings are installed, to middle bushings of each axle the clamp base is welded for installation of wind tunnel on it. Half-hinges are welded to extreme bushings of each axle, and lugs are welded to them from above, in which posts-supports are installed for a visor, which consists of two parts connected by a piano hinge made with possibility of changing the central angle of inclination of the protective visor in accordance with the angle of roof inclination. From below to each half-hinge there are two welded guides tightly pressed to the corresponding roof slope.
EFFECT: higher operational reliability of the roof.
