Protection system for tension members of a structure for catching ice accumulations releasing from a tension member

摘要

The invention relates to a protection system for tension members (4, 5) of a building (1), in particular for a stay cable of a bridge structure, consisting of a protection device for tension members (4, 5) for collecting ice accumulations detaching from a tension member (4, 5) and a tension member (4, 5), the tension member (4, 5) being anchored to the structure (1) with its first end in a first abutment (6) and with its second end in a second abutment (7). With the section running between the abutments (6, 7), the tension member (4, 5) is exposed to climatic conditions. In order to ensure absolute protection against falling collections, the invention provides for the protective device to comprise a tubular casing (11) which surrounds the tension member (4, 5) on the circumference. In a first operating position, the tubular casing (11) is axially compressed or folded on a partial longitudinal section of the tension member (4, 5) and can be brought into a second operating position by means of a drive device, in which the tubular casing (11) extends in the stretched state the length of the tension member (4, 5) extends.
