ANTI-SEISMIC ISOLATOR OF THE SLIDING PENDULUM TYPE FOR PROTECTING CONSTRUCTIONS
An anti-seismic isolator of the sliding pendulum type (1) for protecting constructions, comprising a lower plate (2) adapted to be arranged close to a foundation structure, an upper plate (3) arranged above the lower plate (2) along a linear axis (Y) and adapted at least to contribute to supporting an elevated structure to dissipate the kinetic energy transmitted to the elevated structure by a natural phenomenon or by a human-caused event and provided with a high release of total energy, and a sliding and dissipation pad (4) arranged simply resting against the lower plate (2) and the upper plate (3) between which it is interposed to swing freely on the inner surface (2a, 3a) of the lower plate (2) and the upper plate (3) according to one or more random side directions, orthogonal to the linear axis (Y), alternately between an equilibrium position, assumed in absence of the natural phenomenon or the human-caused event, wherein the sliding and dissipation pad (4), the lower plate (2) and the upper plate (3) are substantially coaxial to each other, and a plurality of instability positions, assumed while the natural phenomenon or the human-caused event is in progress, wherein the sliding and dissipation pad (4), the lower plate (2) and the upper plate (3) are offset from each other, to dissipate the kinetic energy of the natural phenomenon or the human-caused event, transmitted to the elevated structure. In particular, the two outer faces (4a, 4b), axially opposite to each other along the linear axis (Y), of said sliding and dissipation pad (4) are coated with a laminar layer (5), which is made of thermosetting resin and is in direct contact with both at least one of the outer faces (4a, 4b) of the sliding and dissipation pad (4) and the inner surface (2a, 3a) of the lower plate (2) and/or of the upper plate (3).
