Abstract

Disclosed is an aseismic support structure having one end secured to a fixed floor and another end connected to a subject structure placed on a floating floor. The aseismic support structure includes a toggle bar, an attachment section and a mounting section. The toggle bar has a universal joint at each end and is adjustable in its length to have a predetermined length. The universal joints are rotatable around axes in the horizontal and vertical directions, respectively. The attachment section is connected to the toggle bar through one of the universal joints, and has at another end another universal joint comprising a vertical rotation section. The mounting section is connected to the attachment section through another universal joint, and secures the equipment.
