METHOD FOR PREVENTING OVERTURN OF TRESTLE

摘要

Problems to be Solved: To securely prevent a portable pedestal for which anchor bolts cannot be used from tipping over due to earthquakes by simple works.;Means to Solve the Problem: Provided in a portable pedestal 1 for supporting a transfer conveyer 3 are the same number of vibration-damping pads 6 as that of the feet 5. The vibration-damping pads 6 include an adhesive layer on the top and bottom sides of their gel elastic body 7 and hold a support member 8 capable of plastic deformation at the center of the gel elastic body 7. The vibration-damping pads 6 are interposed between the feet 5 and a foundation F to allow the load of the pedestal 1 to compress the support members 8 and the gel elastic bodies 7 so that the vibration-damping pads 6 may block the propagation of the vibrations caused by an earthquake from the foundation F to the pedestal 1.
