SEISMIC INSULATING STRUCTURE FOR EXISTING BUILDINGS

摘要

A seismic insulating structure (1) for buildings consists of an; insulating platform (2) arranged under the foundations| (3) of a building (3a) and comprising a top block (4), a bottom block (5) separated from the top block (4), a plurality of seismic insulators (6) arranged between the top block (4) and the bottom block (5), an inner underground wall (7) fixed on the bottom to the top block (4) and arranged so as to contain the ground that surrounds said building (3a) and an outer underground wall (8) fixed at the bottom to the bottom block (5) and arranged about said inner underground wall (7); said inner underground wall (7) and said outer underground wall (8) combinedly defining a seismic joint for their entire height (9).
