DAMPING DEVICE FOR ANTI-SEISMIC STRUCTURES

摘要

Damping device for anti-seismic structures, comprising a support (7, 7') having, formed at the bottom thereof, a seat (107, 107') housing first vertical damping means (6, 6') mounted at the bottom on a foot (5, 5') supported by suitable bearing means (4, 21) fixed to a structure (16) supporting a pillar (1) of an anti-seismic structure; this foot (5, 5') is able to shift or pivot with respect to these bearing means (4, 21) and this support (7, 7') has an upper part (207, 407') co-operating with second horizontal damping means (8) fixed on one side to this upper part (207, 407') of this support (7, 7') and on the other side to the inner side wall of a seat (2, 19) for housing this upper part (207, 407'), formed internally at the base of the pillar (1) or externally between the base of the pillar (1) and this support structure (16); this pillar (1) has, at the base, a plate (9, 9') with a suitably shaped central hole (109, 109') inside which an end or middle section of this support (7, 7') engages.
