<p>The invention aims at isolating the foundations and the remaining part of the building from the earthquake. The antiseismic plates ( 2) are hermetic containers divided into two parts. Vacuum has been produced in part 'B' so that most of the longitudinal or primary seismic waves propagating through the solids and fluids are cancelled. A pressurized liquid has been introduced into part 'A' to cancel the transversal or secondary waves that propagate through the solids. 'F1' is the lateral force of the surface seismic wave acting upon the plate and producing a pressure on the liquid pressing against the base (1) with nil results. 'F4' is the decompensation of the faces pressing against the ground. The invention can be used in all types of foundations and large surfaces to preserve infrastructures, etc. It can alternatively be used for conical bases, buried walls, beam supports, etc.</p> |
