Layered support

A method to restrict the compression of a layered elastomeric support supporting a building structure alternately comprising one or several elastomeric layers and one or several reinforcing layers,

• wherein at least one elastomeric layer comprises an elastically compressible elastomeric block with a top surface and a bottom surface situated opposite each other and with at least one bulging surface in between them,
• wherein the elastomeric block has a height amounting to the distance between the top surface and the bottom surface,
• wherein the bulging surface of the elastomeric block bulges out elastically in a free space when the elastomeric block is compressed between the top surface and the bottom surface by a load of the building structure, such that the height of the elastomeric block amounts to a compressed height,
• wherein at least a first reinforcing layer comprises a rigid top plate which abuts against the top surface of the elastomeric block and at least a second reinforcing layer comprises a rigid bottom plate which abuts against the bottom surface of the elastomeric block,
• wherein at least one of the top plate and the bottom plate is provided with a raised edge, wherein the raised edge has a surface extending at least partly opposite the bulging surface,
• wherein elastic compression of the elastomeric block is restricted by making the bulging surface of the elastomeric block that bulges out elastically in the free space, rest at least partly against the raised edge when a specific elastic compression of the elastomeric block is exceeded.

A method for manufacturing a layered support for supporting a building structure which alternately comprises one or several elastomeric layers and one or several reinforcing layers, wherein at least one elastomeric layer comprises an elastically compressible elastomeric block with a top surface and a bottom surface situated opposite each other and with at least one bulging surface in between them, wherein the elastomeric block has a height amounting to the distance between the top surface and the bottom surface, wherein the bulging surface of the elastomeric block bulges out elastically in a free space when the elastomeric block is compressed between its top surface and its bottom surface by a load of the building structure, such that the height of the elastomeric block amounts to a compressed height, wherein at least a first reinforcing layer comprises a rigid top plate which abuts against the top surface of the elastomeric block and at least a second reinforcing layer comprises a rigid bottom plate which abuts against the bottom surface of the elastomeric block, wherein at least the top plate and/or the bottom plate are/is provided with a raised edge, wherein the raised edge has a surface extending at least partly opposite the bulging surface and wherein the bulging surface bulges out elastically in the free space until the bulging surface abuts at least partly against said surface of the raised edge when the elastomeric block is compressed between the top surface and the bottom surface and the height is decreased to a minimum height,

• and providing the raised edges with a curved surface opposite the bulging surface, and forming a curvature of the curved surface of the raised edges so as to correspond with curvature of the surface of the bulging surface in the free space when the elastomeric block is compressed to a certain height.
