Definitions

  • the invention relates to a reinforced elastomer bearing for supporting heavy components, in particular for bridges, the elastomer material of which is penetrated by reinforcement plates which are separated from one another by elastomer layers and are connected to them in a shear-resistant manner by vulcanization.
  • Previously known armored elastomer bearings of this type which generally serve to support heavy components, primarily for bridges, consist of a rubber-like elastic material, such as elastomer or natural rubber, which is interspersed with layers of reinforcement plates are connected to each other in a shear-resistant manner by vulcanization with the elastomer.
  • a reinforced elastomeric bearing When such a reinforced elastomeric bearing is loaded, each elastomer layer between the reinforcement plates is known to endeavor to swell out between the two adjacent reinforcement plates, but is prevented from doing so thanks to the shear-resistant connection between the reinforcement plates and the elastomer. This creates a state of compressive stress in the elastomer.
  • the invention has for its object to form an elastomeric bearing of the type mentioned in such a way that such unevenness and in particular a non-parallelism between the building surface and the foundation can be accommodated.
  • a flat capsule press which can be placed under pressure is embedded in the elastomer of the bearing between two adjacent reinforcement plates and which, in a manner known per se, consists of two sheets welded to one another at their edges via an articulated bead which, together with the beads, form a cavity which receives the pressure medium and is variable under pressure, and elastically surrounds the capsule press in the elastomer of the bearing by vulcanization.
  • liquid, oil or cement mortar is pumped under pressure into the capsule press by means of a hydraulic pump.
  • This causes the capsule press to expand and push the upper and lower halves of the reinforced elastomer bearing apart.
  • the elastomer bearing can adapt to unevenness and non-parallelism of the two contact surfaces, as described above in a) and b), so that the elastomer bearing according to the invention comes into perfect contact with the building.
  • CH-PS 439371 tilt-resistant reinforced elastomer bearing
  • CH-PS 439371 tilt-resistant reinforced elastomer bearing
  • the height adjustability is already known for steel roller bearings (DE-PS 1 036 487) and is achieved in a generally known manner by cavities filled with liquid.
  • pure plain bearings have already been proposed (FR-PS 2 118 057), which have a hollow body, the walls of which slide against one another and into which a lubricant can be injected in order to reduce the frictional resistance;
  • the hollow body is not used to lift the structure or to move tion of the elastomer part, but only the sliding process.
  • Elastic building construction bearings (DE-OS 1658939), tilting bearings for bridges (DE-PS 1160873), bridge bearings (FR-PS 1516939), hydraulic tilting bearings (DE-AS 2918781) as well as slide and deformation bearings (DE-OS 21 54630 ) already known, which are formed, for example, by a capsule press, and in some cases also have pressurizable cavities in order to cope with various movements. a. To enable height adjustments of the warehouse in question. In the elastomer bearing according to the invention, however, the capsule press by vulcanization is an integrated part of the bearing and not only brings about the height adjustability, but also forms a reinforcement similar to the reinforcement plates.
  • such a capsule press can also be pressed with liquid cement mortar as a pressure medium, the cement mortar hardening and the lifting height achieved with it remaining unchanged.
  • the capsule press is usually cemented between two sheets.
  • the elastomer bearing according to the invention is a composite body produced by vulcanization, which unites the structural elements of a reinforced elastomer bearing with a capsule press.
  • the steel sheets between the beads of the capsule press which, as already mentioned, remain without tension during normal use of the capsule press, additionally take on the function of steel reinforcement for the elastomer bearing in the elastomeric bearing according to the invention, by balancing the pressure forces in the elastomer layer absorb the required tensile forces.
  • the elastomer layer between the sheets of the capsule press and the reinforcement plates of the elastomer bearing adjacent to them is kept thinner than the elastomer layer that follows next to the outside.
  • This first relatively thin elastomer layer ensures that the tensile forces introduced into the sheets of the capsule press remain relatively low, since it is known that the tensile forces in the reinforcement plates of an elastomer bearing are proportional to the thickness of the enclosed elastomer layer.
  • the relatively small layer thickness of the first elastomer layer prevents the capsule press from inflating irregularly.
  • this thin elastomer layer ensures good guidance of the deformation of the capsule press through the first reinforcement plate of the bearing.
  • a further advantage of the elastomer bearing according to the invention is given when the reinforcement plates next to the sheets of the capsule press protrude outwardly beyond the bead of the capsule press.
  • the structure thus achieved is covered by elastomer to protect against corrosion and mechanical attacks at the edge area and over the outer reinforcement plate.
  • a liquid such as oil or water can be provided as the pressure medium for the capsule press, with which the capsule press contained in the bearing according to the invention is pressurized.
  • a liquid cement mortar is used as the pressure medium for the capsule press, it hardens after it has put the capsule press under pressure, the elastomeric bearing according to the invention then acting like a reinforced elastomeric bearing with an enclosed hard mortar core.
  • the shape of the capsule press and thus of the entire elastomer bearing according to the invention can be round, oval or even rectangular.
