Seismic reduction deck, rack seismic structure and storage load collapse prevention structure

摘要

PROBLEM TO BE SOLVED: To provide a vibration reduction deck capable of absorbing vibration in the horizontal direction, and decreased in a height dimension.SOLUTION: A vibration reduction deck D1 includes: an inner implement 1 in which four walls of a front wall 11, a rear wall 12 and both lateral walls 13,13 are provided; an outer implement 2 in which four walls of a front wall 21, a rear wall 22 and both lateral walls 23,23 are provided correspondingly to the four walls of the inner implement 1, in the outer periphery of the inner implement 1, and which is provided relatively movably in front and back both lateral directions to the inner implement 1; and vibration absorbing bodies 41,42 which are arranged in each interval in each external surface of the four walls of the inner implement 1, and each internal surface of the four walls of the outer implement 2, and have rubber elasticity. The vibration added to any one of the inner implement 1 and the outer implement 2 is suppressed from transmitting to the other implement by being absorbed by the vibration absorbing bodies 41,42.SELECTED DRAWING: Figure 1
