BUILDING ELEMENT AND METHOD FOR DE-ICING A PLANAR STRUCTURE

摘要

The invention relates to a building element (1) having a planar structure (10), which can be wound up by means of a winding device (115), wherein the building element also has a drive mechanism (2), with which the planar structure (10) can be caused to vibrate. Moreover, the invention relates to a method for de-icing a planar structure (10) of a building element (1), wherein the planar structure (10) can be wound up with a winding device (115) and is mounted such that it can vibrate and/or generate surface vibrations, wherein the planar structure (10) is caused to vibrate with a drive mechanism (2), so that the mechanical binding between an ice layer and the planar structure (10) underneath is released.
