Vibro-impact energy absorbing device using composite crush tube and Vibration Damping Device for Building having the same

摘要

The present invention relates to an inner cylinder having a first member made of an inner hollow cylindrical shape; An outer cylinder having a second member for receiving the first member in an inner hollow; An end plug passing through the inner hollow of the second member and having a center pin whose end is disposed in the first member inner hollow; A compression wedge provided so as to be in contact with the outer peripheral surface of the second member of the outer cylinder; A compression slider provided so as to abut the outer surface of the compression wedge; A first composite tube and an external spring which abut one side surface and the other side surface of the compression slider; A tension wedge provided so as to be in contact with an inner peripheral surface of the first member of the inner cylinder; A tensioning slider provided so as to abut the inner surface of the compression wedge; And a second composite tube and an inner spring that abut one side surface and the other side surface of the tension slider, respectively, and an inner spring. According to the present invention, by using the composite tube, the impact energy according to tensile and compressive impact loads can be effectively absorbed by the above-described structure, and the shock energy absorbing device can be applied to a building to be used as a vibration- An advantageous effect occurs.
