Elastic foundation

A support element with an elastically compressible stabiliser and a pre-stress element, wherein:

• the support element has a supporting surface,
• the elastically compressible stabiliser comprises an elastomer and connects to the supporting surface,
• the elastically compressible stabiliser extends between the supporting surface and the pre-stress element,
• in a compressed state of the stabilizer, the stabilizer is elastically compressed between said pre-stress element and the supporting surface,
• wherein the stabiliser has a bulge side which bulges out elastically in the compressed state of the stabiliser,
• wherein the stabiliser extends at least partly in a stabiliser chamber having a free space between the bulge side and a wall of the stabiliser chamber,
• wherein the bulge side of the stabiliser is free and its bulging is not hindered in a free position when a given authorised compression of the stabiliser is not exceeded,
• wherein the bulge side of the stabiliser bulges out up against the wall of the stabiliser chamber which prevents any further bulging in a blocked position when the stabiliser is being compressed and the given authorised compression is exceeded.

A method for fastening a support element to a base,

• wherein the support element is fastened to the base with a fastening element via a stabiliser and an insulator, wherein said stabiliser and said insulator comprise elastically compressible elastomer dampers,
• wherein the support element is not allowed to make direct contact with the fastening element and/or with the base and wherein a lower support face of the support element, via the insulator, is made to rest on a base support surface of the base,
• wherein the stabiliser is elastically compressed between a pre-stress element and the insulator and simultaneously the insulator is elastically compressed between the lower support face and the base support surface,
• wherein, when a load is exerted on the support element by a tensile force, the stabiliser will be elastically compressed and said stabiliser will bulge out elastically via a bulge side, or, when a load is exerted on the support element by a pressure force, the insulator will be elastically compressed and said insulator will bulge out elastically via a bulge side,
• wherein, as a result of the load exerted on the support element, the support element is subjected to a deflection,
• wherein, when the load includes the tensile force and said tensile force exceeds a limit value, the bulging of the bulge side of the stabiliser is restricted to up against a wall of a stabiliser chamber, as a result of which stiffness of the stabiliser drastically increases and any further deflection is prevented and restricted to an authorised deflection.

A method for securing an elastic support for uncoupling foundations and buildings and/or cores of buildings,

• wherein a support element is clamped between a stabiliser and an insulator, wherein said stabiliser and said insulator comprise elastically compressible elastomer dampers,
• wherein the support element is fixed to a base with a fastening element via said stabiliser and said insulator, such that the support element does not make direct contact with the fastening element and/or with the base and wherein the support element is made to rest on the base via the insulator,
• wherein the stabiliser and the insulator are compressed between a pre-stress element and the base,
• wherein, in case a load is exerted on the support element by an upward tensile force, the stabiliser will be elastically compressed and said stabiliser will bulge out elastically via a bulge side on the one hand, or, when a load is exerted on the support element by a downward pressure force, the insulator will be elastically compressed and said insulator will bulge out elastically via a bulge side on the other hand,
• as a result of which the support element is subjected to a vertical upward and/or a vertical downward deflection,
• wherein, when the load comprises the upward tensile force and said upward tensile force exceeds an upward limit value, the bulging of the bulge side of the stabiliser will be restricted to up against a wall of a stabiliser chamber, as a result of which the stiffness of the stabiliser will drastically increase and any further deflection will be prevented and restricted to an authorised deflection.
