Definitions

  • the invention relates to a bearing for structures according to the preamble of claim 1.
  • large cantilevered structures in particular bridges, it is necessary to provide a compensation for the occurring elongations at the support points.
  • length changes of more than 1 meter may occur.
  • at least at one support point, usually at several, the building or the bridge against the foundation is displaced.
  • slide bearings are known from the prior art, wherein a fixedly mounted first bearing element is arranged on a structure or a bridge, which is supported on an opposite, connected to the foundation, second bearing element.
  • the shorter bearing element As a rule, it is required that the smaller of the two bearing elements always rests completely on the other bearing element.
  • the length of the longer bearing element on both sides must be longer than the shorter bearing element by the extent of the expansion path. In an exemplary case, an elongation of approximately 1 m is expected for a bridge length of 1 km. In this respect, therefore, in this example, with a length of the shorter bearing element of 2 m, the longer bearing element must be at least 4 m long. In this case, it is necessary that further the bearing elements have sufficient rigidity. Furthermore, it should be noted that the bearing elements have sufficient inherent rigidity, so that point-like or local loads on the sliding surface are avoided. This is the only way to ensure trouble-free gliding over a long period of use.
  • a related problem is that the assembly of a long bearing element resulting from the requirements in a massive design and the associated high weight in the case of particularly high pillars as a foundation only with considerable technical effort is possible.
  • roller bearings were often used in the prior art.
  • a roller is arranged between the upper and the lower bearing element.
  • the upper bearing element moves under a rolling movement of the roller along the lower bearing element.
  • comparatively short bearing elements are sufficient to ensure the necessary displaceability.
  • the longevity of the roller bearings can not, as expected, can be guaranteed.
  • the present high loads lead, in particular under the function-related rolling motion, often to a continued material damage of the soft inner core with a subsequent tearing of the hardened outer periphery. This in turn requires a bridge renovation, which in turn is associated with extremely high costs. Therefore, under all circumstances, it is important to preserve the longevity of appropriate bearings.
  • the object of the present invention is to enable a bearing for structures, in particular bridges, in which, in relation to the leadership can be used with the known plain bearings significantly reduced bearing elements.
  • a bearing for structures initially comprises a first directly or indirectly connected to the building, substantially plate-shaped bearing element. Furthermore, the bearing has a second support element which is supported on the foundation and essentially plate-shaped.
  • the first bearing element has a second bearing element facing sliding surface and the second bearing element facing the first bearing element sliding surface.
  • the first bearing element with the structure or the bridge relative to the second bearing element and the foundation is displaceable.
  • connection of the first bearing element with the building and the second bearing element with the foundation does not necessarily relate to a rigid and firm assembly. Rather, the bearing elements can also be coupled resting or articulated with the building or foundation. At least, the first bearing element is also moved in a longitudinal displacement of the structure, whereas, where the second bearing element remains with the foundation in place.
  • a third substantially plate-shaped bearing element is now arranged between the first and second bearing element.
  • the third bearing element is displaceable, both with respect to the first bearing element, as well as with respect to the second bearing element. This is realized by the opposite sliding surfaces on the third bearing element. This creates a first sliding pair between the Sliding surface on the first bearing element and the associated sliding surface on the third bearing element and a second sliding pair between the sliding surface on the second bearing element and the associated sliding surface on the third bearing element.
  • the total founded path of the first bearing element relative to the second bearing element by adding the Gleitweges from the first to the third bearing element with the sliding path of the second bearing element to the third bearing element, whereby it is possible to use significantly lighter bearing elements. Due to the now largely halved storage paths in the individual slip planes, this consequently also leads to a reduction of the eccentricity with regard to the transfer of the load from the building to the foundation. Especially with high pillars, the buckling load is significantly reduced. To enable appropriate sliding movement in a primary
  • the sliding surfaces in this primary direction basically linear. It is particularly advantageous if the sliding surfaces are flat overall. Thus, in particular the costs in the manufacture and assembly of the bearing elements can be kept low, at the same time the proper investment of the sliding surfaces can be ensured together.
  • the sliding surface of the first bearing element and the associated sliding surface of the third bearing element and / or the sliding surface of the second bearing element and the associated sliding surface of the third bearing element in a cylinder to execute form.
  • the longitudinal displacement is unchanged guaranteed, with a displacement of the sliding surfaces is ensured to each other in deformations of the structure or the bridge transversely to the longitudinal movement, without causing uneven loading conditions in the sliding layers.
  • first and / or second bearing element and / or the third bearing element has guide means which substantially prevent a corresponding relative movement between the bearing elements in the direction of the secondary sliding movement.
  • guide means ensures that, in the case of repeated transverse loading of the first bearing element relative to the second bearing element, there is no displacement of the third bearing element beyond the bearing surfaces.
  • a linear guide can be provided on the one hand in both sliding planes.
  • the first friction coefficient between the mutually facing sliding surfaces of the first and third bearing element is selected differently to the second coefficient of friction between the mutually facing sliding surfaces of the second and third bearing element.
  • this solution can specifically cause a preferred sliding movement.
  • the gliding will take place predominantly in a gliding plane.
  • the third bearing element remains in relative rest to the corresponding bearing element.
  • the first coefficient of friction is smaller than the second coefficient of friction.
  • the third bearing element in the present case remains substantially at rest and is thus arranged in the middle of the pillar.
  • the sliding thus takes place mainly between the first bearing element and the third bearing element.
  • the load lying on it is mainly transmitted to the center of the pillar.
  • the first bearing element in each case has at least one follower-like stop in the direction of the sliding movement at both ends of the sliding surfaces.
  • the follower-like stop comes to rest on the third bearing element and limits the movement of the sliding path between the first bearing element relative to the third bearing element.
  • the follower-like stop ensures that no sliding of the third bearing element takes place beyond the sliding surface of the first bearing element.
  • the second bearing element in the direction of the sliding movement at both ends of the sliding surfaces in each case at least one driver-like stop.
  • the follower-like stop of the second bearing element comes to rest on the third bearing element.
  • the sliding path between the third bearing element is limited relative to the second bearing element. So is the same ensures that no sliding of the third bearing element can take place beyond the sliding surface of the second bearing element.
  • Fig. 1 shows an embodiment of the bearing according to the invention
  • FIG. 4 shows a cross section to the embodiment according to FIG. 1.
  • a bearing 01 for buildings 02 is an example sketched.
  • the bearing 01 comprises a first bearing element 10, which is attached to the structure 02.
  • the bearing 01 has a second bearing element 12, which in this case is connected to the foundation 03.
  • the third bearing element 14 is provided according to the invention.
  • the bearing elements 10, 12 and 14 corresponding sliding surfaces 1 1, 13, 15 and 16.
  • the primary direction of movement is outlined. It is obvious how a sliding between the first bearing element 10 and the third bearing element 14, as well as a sliding of the third bearing element 14 relative to the second bearing element 12 can take place.
  • Figure lb shows a first deflection of the structure 02 relative to the foundation 03.
  • the length LI Q of the first bearing element 10 is substantially greater than the length L14 of the third bearing element. The same applies to the length Li 2 of the second bearing element 12 in relation to the third bearing element 14.
  • a first bearing element 22 is connected to the structure 02.
  • the second bearing element 23 is in this case connected to the foundation 03 accordingly.
  • the roller 24 is located between the first bearing element 22 and the second bearing element 23. It is obvious that a movement 04 of the structure 02 relative to the foundation 03 is made possible by rolling the roller 24.
  • a plain bearing 3 1 is sketched from the prior art for comparison in Figure 3a.
  • a first bearing element 32nd firmly connected to the structure 02.
  • the second bearing element 34 is likewise arranged on a foundation 03.
  • a displacement of the structure 02 in the direction of movement 04 relative to the foundation 03 leads to a sliding of the sliding surface 33 of the first bearing element 32 relatively along the sliding surface 35 of the second bearing element 34. It is obvious that to realize a large range of motion at least one bearing element must be significantly larger , provided that the other bearing element should always rest completely with its sliding surface.
  • FIG. 3 b outlines the structure 02 in FIG. 3 a in a position displaced by the path X. It is obvious that in order to realize the maximum movement space, the length L 32 of the first bearing element 32 has to be longer by the total path than the length L 34 of the second bearing element. In this respect, this leads to considerable lengths, which leads to considerable expense in the production of storage, especially for long bridges.
  • the weight distribution on the second bearing element 34 is dependent on the design of the bearing elements 32 and 34, and the rigidity of the substructure or superstructure. In this respect, it may well come to a center of gravity distribution in a displacement of the first bearing element 32. As a result, a large eccentricity E34 can act on a pillar 03.
  • FIG. 4 a possible cross-section to an embodiment according to the embodiment from FIG. 1 is sketched by way of example.
  • the width Bi o of the first bearing element 10 is made larger than the width Bi 2 and B 14 of the sliding surfaces 13 and 16 of the second and third bearing element 12 and 14.
  • Bearing element 12 is provided.
  • the third bearing element 14 always remains in the central position with respect to the second bearing element 12. It is obvious that the third bearing element 14 can only perform a movement in the primary direction of movement 04. Notwithstanding a solution according to FIG. 4, it is likewise possible to provide guiding means on the first bearing element 10 too, so that a transverse movement 05 of the structure 02 is prevented. Likewise, it is possible to turn the assembly over and allow sliding between the second and third bearing element in the transverse direction 05. Taking into account a usually required angle compensation between the structure 02 and the foundation 03, it is also conceivable (when looking at the section in Fig.
  • At least one bearing point between the first and third bearing element 10 and 14 and / or the second and third bearing elements 12 and 14 instead of a planar shape as a cylinder jacket surface to choose.
  • an angular compensation can take place in the transverse direction.
  • the choice of a cylinder jacket surface allows the guide of the third bearing element 14 in the middle relative to the first and / or second bearing element.
