RUBBER VIBRATION ISOLATOR FOR FLOOR SUPPORTING LEG HAVING BOTH HIGH LOAD CARRYING PERFORMANCE AND HIGH VIBRATION RESISTANCE

摘要

PROBLEM TO BE SOLVED: To secure high load carrying performance while securing high sound shielding performance of a dry sound shielding double floor.;SOLUTION: A cylindrical drilled hole 3 for shape retaining which is vertically formed in a rubber vibration isolator at the center position is formed such that a recessed fitting surface 2 for recessed fitting is arranged on the inside thereof to prevent the rubber vibration isolator is not compressed or expanded by a floor load so as to develop a high shape retainability. By this, to increase the vibration resistance, the hardness of the rubber vibration isolator 1 can be lowered to 65° or less.;COPYRIGHT: (C)2005,JPO&NCIPI
