PROBLEM TO BE SOLVED: To stably support and protect equipment by ceiling suspension without a necessity of a large movable space by effectively absorbing inputted vibration energy into a small space.SOLUTION: There is provided an anti-vibration suspension earthquake damping structure 1 which is a structure for supporting equipment W by ceiling suspension and comprising: a plurality of suspension bolts 3 whose upper ends are screwed into fixing implements 2 arranged at a ceiling frame F; connecting implements 5 which are arranged at respective lower ends of the suspension bolts and connected to connecting pieces 4 fixed to the equipment; and a vibration damping member 15 which consumes the vibration energy of inputted vibration and reduces vibration loads acting on the suspension bolts. In the structure, the vibration damping member comprises first engagement members 20 fixed to the equipment and second engagement members 30 arranged at the suspension bolts and relatively movably engaged with the first engagement members while being imparted with prescribed resistance forces. The structure consumes the vibration energy accumulated in the suspension bolts by the relative movement of the first engagement member and the second engagement member. |
