ABSTRACT:
An earthquake resistant mount is made up of two monoblock elements of a hard rotproof material possessing great resistance to abrasion for supporting buildings and constructions. The earthquake resistant mount is secured to the infrastructure and to the superstructure of the building. A first monoblock element is formed of a preferably circular horizontal rubbing plate including a cone frustrum at its center. A second monoblock element has the shape of a circular cap with a flat blind end and covers the first element so that said blind end of the concavity is in contact with the horizontal plane situated at the top of the cone frustrum, and the horizontal peripheral edge is in contact with the rubbing plate. An annular space is furnished between the internal lateral wall of the circular cap and the lateral wall of the cone frustrum, and the horizontal peripheral edge is in contact with the rubbing plate. The annular space between the internal lateral wall of the cone frustrum allows a relative lateral displacement and of at least one damping ring secured or not secured to the internal lateral wall of the circular cap and/or the lateral wall of the cone frustrum. The damping ring fills all or some of said annular space. A layer of a resilient and crush-resistant polymer is interposed horizontally at any level through the entire thickness of the material of said elements. The layer allows to absorb low-amplitude tremors before the monoblock elements slip.
