FIELD: construction.
SUBSTANCE: anti-icing device is made in the form of a cover from neoprene rubber, which is attached to an icy surface and inside which rubber tubes are arranged, which are connected to a compressed air source. Stiff membranes are installed inside the tubes, and the compressed air source is provided with a control system including controls for pressure and frequency of periodic air supply; with that, frequency values for each section of the device between the membranes by means of feedback sensors are capable of being automatically set for natural oscillation frequency of the same section, which varies depending on destruction degree of the ice formed in it.
EFFECT: operating reliability of building roofs.
