SAND-SKELETON IN HYDRAULIC TORUS BUFFER, FUNCTIONING BY WAY OF SUPPORTING ELEMENT AS LONG AS THE PROTECTED STRUCTURE IS SUBJECTED TO WIND LOAD ONLY AND NO EARTHQUAKE EXISTS

摘要

The invention is intended to improve the so-called hydraulic torus buffer as described for example in the USA-patent 4,887,398, in such a way that the horizontal soil movements during earthquakes do not affect the supported building (10), but wind load cannot effectuate breaking adrift due to a consolidated sand-skeleton (1) inside, bearing the structure (10) in the absence of wind load. The skeleton (1) can also function as an isolated earthquake protecting system, whether or not enveloped by a torus buffer or any other wrapping, while granulated and fluidum-like materials (4) different from sand (6) are also suited for the above-mentioned purpose.
