METHOD OF REMOVING ICICLES ALONG BUILDING ROOF PERIMETER Russian patent published in 2018 - IPC E04D13/76 

FIELD: construction.

SUBSTANCE: invention relates to the field of construction, in particular to a method for removing icicles along the perimeter of a building roof. Method includes a power action on the icicles with the help of actuating electromechanical mechanisms (AEM), that together with the "wire-string" (WS) are placed under the roof edge. On the way of water runoff, the ends of the WS are fixed by means of brackets that allow changing the tension of the WS, the tension force of the WS is chosen taking into account the distance between the brackets the way proper resonant frequencies of the string, determined from the expression:

where f is the oscillation frequency (Hz), l is the length of the string (m), F is the string tension force (N), ρ is density of the string material (kg/m)³, S is the cross-sectional area of the string (m²), are outside the range of resonant frequencies of the elements of the roof structure.

EFFECT: technical result of the invention consists in simplifying the manufacture of an apparatus for removing icicles.
