Sliding bearing for supporting civil or structural engineering works
A sliding bearing, arranged for supporting civil or structural engineering works, such as for example bridges or buildings, seismically isolated or not, where the bearing comprises A) a base (3) and an upper support (5); B) a sliding element (7, 7′) interposed between the base (3) and the upper support, and against which the base (3) and the upper support rest. The sliding element (7, 7′) comprises at least one layer (11, 11′, 11″, 11III) made of a sliding material (9) comprising in turn B.1) a content by weight equal to or greater than 50% wt of one or more fluorinated polymers; B.2 a content by weight comprised between 1-20% wt of boron nitride in hexagonal form. The mechanical properties of the sliding material (9) for use as a structural bearing or an anti-seismic isolator, are less sensitive to a temperature and environmental humidity with respect to known sliding materials.
