  • these connections are designed in such a way that the connections on the building side have at least one element 22 filled with granulate, via which the frictional connection takes place. Examples for a lower connection are shown in FIGS. 18 and 19, an example for an upper connection is shown in FIG. 20.
  • an elastic element 48 is provided below the at least one element 22 filled with granules. This can often be preferred, but is not always mandatory.
  • this or the elements 22 filled with granulate are received in a recess in the support body 12.
  • the supporting body itself can absorb lateral forces, so that the elements filled with granulate, whose covers usually consist of cardboard or a similar non-rigid material, are also used in supports of heavy concrete or reinforced concrete stairs that can.
  • a housing element 120 can alternatively or additionally be provided. This applies to both the upper and lower end supports.
  • a cavity can also extend into the wall or the bottom of the housing, in which the granulate (which can also be in the form of an element filled with granulate but also in the form of a sand bed) is arranged so that a lateral evasion is excluded.
  • An enclosure element can also be provided here. Due to the greater weight, in the case of a concrete or reinforced concrete staircase, the lateral enclosure (housing) (through the supporting body, through the building or through a separate housing element) is even more important than in the case of a lightweight staircase.
  • a connection in particular a lateral connection, can be made via a peg-shaped connection 16 on the supporting body side, which extends laterally from the supporting body 12.
  • the seal 56 can be a foam.
  • the seal does nothing to exclude the force.
  • a housing element 120 should also be provided here.
  • At least some of the elements 22 filled with granulate can also be constructed as shown in FIGS. 25 and 26:
  • This element has a structural body made of an elastic material, through which at least one cavity is formed (usually several cavities), which are filled with granules. The end faces are closed with closures.
  • An element with this structure could be installed horizontally (with horizontally extending cavities) or vertically (with vertically extending cavities).
  • the frictional connection takes place partly (usually predominantly) through the granulate, although some of the frictional connection can also take place via the structural body, its elasticity ensuring that some of the frictional connection takes place via the granulate, which is necessary, to enter the sound energy to be dissipated into it.
  • the outer shell of the element 22 filled with granules is "automatically" watertight.
  • Such an element 22 filled with granules could (even if after current state of knowledge is not regarded as ideal) can also serve as a decoupling element 44 or as part of such a element.
  • damping takes place both in the area of the tread elements and in the area of the building connections, but this is not mandatory, in particular the provision of step elements such as they were described for example in FIGS. 1 to 4a, and / or the use of pipes filled with granulate in the area of the connections brings about a strong improvement in the acoustic properties.
  • FIGS. 32 and 33 show the application of the invention to a single step, in which a single step element 18 is connected to a wall W by means of support elements 16.
  • the individual step element 18 can be designed as a step element as described in FIGS. 2 to 4a, or it can be an ordinary single step element made of flolz.
  • the connection of the support elements 16 to the wall takes place as described above with reference to FIGS. 5 to 7.
