Definitions

  • the invention relates to a bearing for a ball container, which has a lower spherical support section, with a concrete foundation, the surface facing the support section is curved substantially parallel to the spherical support section, a support layer of elastomeric elements being arranged between the curved surface and the support section.
  • Such storage is known from CH-PS 600 110.
  • the elements forming the support layer consist of thin plates which are firmly connected to the spherical support section, leaving narrow joints, for example by gluing.
  • the joints between the support plates are necessary to allow the support plates to deform under load and are filled with a soft plastic sealant.
  • the elastomeric material of the support plates is homogeneous, which means that it is incompressible, so that the support plates have only a limited spring travel in the event of elastic deformation while maintaining the volume. This can have an adverse effect on the behavior of the ball container resting on the support layer, for example when earthquakes occur.
  • the manufacturing the support layer is very labor-intensive, as a result of which the production costs are relatively high.
  • the invention has for its object to improve the storage of the type mentioned in such a way that it can be manufactured more easily and therefore at significantly lower cost, and that the storage behavior of the ball container on the support layer is more stable even in the event of earthquake loads.
  • the elements consist of bodies which touch one another at least at some points on their circumference and which deform elastically when subjected to a load with a decrease in volume.
  • This design of the elements makes it easier to build up the support layer, because it is no longer necessary for them to have a regular outline, because there must be no joints between them to make room for the elements to rebound. This also eliminates the need to fill joints with soft plastic sealant.
  • the use of an elastomeric material, the volume of which decreases under load, results in a greater spring travel for the elements, which has a favorable effect on the damping behavior of the support layer and thus on the stability of the ball container resting on it.
  • a ball container 1 has in its lower region a spherical support section 2 which extends over a central angle ⁇ of approximately 75 °.
  • the ball container 1 is made of steel and is welded together in a manner known per se from a large number of appropriately curved plates. It is used to store gases, liquefied gases and / or liquids.
  • a foundation 3 which in its lower part consists of a compacted gravel bed 4 and above that of reinforced concrete 5.
  • the surface 6 of the concrete foundation 5 facing the support section 2 is concavely curved, so that there is an intermediate space of substantially constant thickness between this surface 6 and the underside of the support section 2.
  • This intermediate space is filled with a support layer 7, which consists of a layer of elastomeric elements 8 (Fig. 2).
  • a seal 13 which surrounds the support layer 7 and which protects the intermediate space filled with the elements 8 against the ingress of liquids.
  • the elements 8 have a regular hexagonal contour and are arranged so as to be touching one another in the contact area, which is delimited by the somewhat smaller central angle ⁇ (FIG. 1).
  • the other quadrants in FIG. 2 are therefore also covered with elements 8.
  • the elements 8 consist of an elastomeric material which has a cellular structure, so that it deforms elastically when loaded with a decrease in volume.
  • the elements 8 are relieved, for example as a result of the decreasing filling weight of the ball container 1, the volume of the elements increases again. This behavior of the material results in a relatively large spring travel for the elements 8.
  • a cellular polyurethane elastomer can be used, which is commercially available, for example, under the registered brand name "Cellasto".
  • the storage is made approximately as follows. After excavating a correspondingly large construction pit, the gravel bed 4 is first created and then the concrete foundation 5 is created with the help of a formwork (not shown).
  • the curved surface 6 is expediently smoothed out by means of a template which is rotatably mounted in a tube 9 which, after completion of the storage, can serve as drainage because it opens out at the lowest point of the curved surface 6.
  • the hexagonal elements 8 are then - as can be seen from FIG. 2 - attached to the curved surface 6, the sections of the elements projecting beyond the edge of the surface being cut off.
  • the spherical support section 2 of the ball container is welded together and checked and then provided on its outside with a thin plastic layer as corrosion protection.
  • the support section is then placed on the support elements 8 and fixed relative to the foundation 3 with the aid of brackets 10 attached to the concrete foundation 5.
  • the ball container 1 is then further constructed by welding on further steel plates.
  • the seal 13 is finally introduced, which can consist of an elastic mass or an elastomeric profile strip.
  • an annular collar 12 is welded to the outside of the support section 2, which ensures that rainwater or condensed water running outside the spherical container drips off before the seal 13 is reached.
  • the ball container 1 In the event that the ball container 1 has to be stress-relieved before being placed on the foundation, the ball container is first completely welded together on a special assembly frame, checked and then stress-relieved. The support section 2 is then sandblasted on the outside and provided with the thin plastic layer. The elements 8 are then glued onto this plastic layer. The foundation 3, which has already been prepared as far as possible, is then concreted up to the elements 8. The assembly frame is then removed, the ball container 1 being deposited on the elastic support layer 7 of the foundation.
  • the elements 8 can also have an outline other than hexagonal, for example triangular, quadrangular, pentagonal or octagonal. They can also have a ring shape or the shape of round disks and have diameters of different sizes.
  • the elements 8 can also be designed as identical bodies made in one mold, it then being expedient to design the outer surface of the elements so that the imaginary cone tip of each element lies approximately in the center of the spherical container in the assembled state is coming.
  • the size, the thickness and the elasticity of the elements 8 can be selected differently depending on the weight of the ball container and its filling.
  • the elasticity can vary within the layer 7, e.g. in the edge area of the surface 6 larger than in the central area.
