An earthquake-proof supporting structure for an access floor having a reinforcing support part is provided to easily maintain a horizontal state of an upper panel of the access floor by rotating a head screw-coupled to a vertical support. An earthquake-proof supporting structure comprises a vertical support(200), a lower support plate(210) for supporting a lower end of the vertical support and a reinforcing support part(300). The reinforcing support part has an upper end integrally coupled to the vertical support and a lower end integrally coupled to an upper surface of the lower support plate. The reinforcing support has an upper end having a dimension smaller than that of a lower end and includes an upper disk(320) and an arc-shaped slope(321) slantingly extending downward from a rim of the upper disk. |
