Definitions

  • the invention relates to a shaft component with the further features of the preamble of claim 1 and a method for its production.
  • Sewer shafts and similar civil engineering structures are usually made by first excavating a pit, placing essentially ring-shaped prefabricated shaft components made of concrete or reinforced concrete on top of one another and then refilling the pit to such an extent that the soil on the outer wall of the stacked shaft components is present.
  • the individual shaft components are provided with upper and lower edges which are complementary to one another, so that a concentric alignment of the shaft rings is forced.
  • the force transmission of the dead weight of the column consisting of shaft components at the joints between the individual, stacked shaft rings takes place according to the prior art via an interposed mortar layer to compensate for dimensional tolerances.
  • the introduction of the mortar into the circular Joints between two stacked manhole rings not only cause difficulties on the construction site due to the workflow, but an uneven application of mortar can also have unfavorable effects on the watertightness and stability of the finished manhole.
  • the necessary sealing element in the form of a rubber ring inserted between the edges of two stacked manhole rings often leaks in conventional manholes manufactured in the prefabricated construction described, since it is contaminated with mortar or the like during assembly.
  • the undefined static conditions mean that stresses occur in the manhole rings made of concrete or reinforced concrete for which they are not designed.
  • manhole rings made of reinforced concrete are only provided with a so-called transport lock, but not with reinforcement that meets the stresses caused by the undefined static load described.
  • the invention is therefore based on the object of inexpensively modifying known shaft components so that when stacking shaft components or shaft rings to form a shaft, the above-mentioned static problems are eliminated.
  • the solution to the problem is characterized in that in a generic shaft component, the upper and lower edges are shaped with respect to one another in such a way that support surfaces are formed which are set apart from one another in the circumferential direction.
  • three support surfaces are formed evenly spaced apart from one another in the circumferential direction, these preferably being projections in the respective lower edge a shaft component are formed.
  • at least one of the edges, preferably the lower, is formed in the circumferential direction in such a way that it has a plurality of steps which are evenly spaced from one another, between which raised bearing surfaces are formed, while the respective other edge has the same radial cross section at all points on the circumference which, in particular, integrates an annular bearing surface on which the preferably three projections of the respective upper shaft component stand.
  • the shaft components according to the invention can be stacked one above the other or placed on top of one another in such a way that the load transfer of the weight on each shaft component and the traffic and earth loads of the shaft components arranged above it takes place in defined zones.
  • the shaft components cannot be tilted or placed obliquely, as a result of which the mortar layer to be introduced is easier and considerably more uniform to apply.
  • the circumferentially spaced support surfaces preferably each of the lower edge, consist of inserted strips of an elastic material, preferably a hard elastomer, which was inserted into the corresponding shape during concreting of the manhole component.
  • the shaft components preferably have an external marking which makes it easier for the shaft-executing construction workers to align the shaft components with one another in the circumferential direction in such a way that the force-transmitting bearing surfaces of each parting line are arranged vertically one above the other.
  • the manhole component according to the invention makes it possible to manufacture manholes with defined static conditions in which cracks in the wall are no longer to be feared under the internal water pressure or the weight of the manhole components or the traffic and earth loads.
  • a sewage shaft 10 consists of a plurality of manhole rings 12A, 12B (and no longer shown) 12C etc., which are closed at the top by a tapering manhole part 14 with a manhole cover 16.
  • the manhole cover 16 is located, for example, at the level of a road, while the shaft components 14, 12A, 12B, etc. shown are in the installed state in the soil, not shown.
  • Each shaft component has an upper edge 18 and a lower edge 20.
  • the upper edge 18 and lower edge 20 are essentially rotationally symmetrical and have radial cross sections such that a shaft component 12A can be placed onto a shaft component 12B.
  • the respective lower edge 20 has an inner circumferential groove 22, corresponding to each upper edge 18 an outer circumferential groove 24, so that the cross sections of the upper edge 18 and lower edge 20 of each shaft component are complementary to one another and, when assembled, engage in a centering manner .
  • a cavity is formed between the two edges, in which a seal 26 is arranged.
  • three strips 28 made of an elastic material are inserted in the lower edge 20 of each shaft component, which - as in FIG. 1 shows - are arranged rotationally symmetrically evenly spaced.
  • the three inserted strips 28 form defined support surfaces 28, which stand up in a defined manner on the annular support surface 30 of the respective upper edge 18.
  • the resilience of the bearing surfaces 28 consisting of an elastomer together with the defined static conditions ensures a defined flow of force which ensures that the individual shaft components remain undamaged despite the internal water pressure and the dead weight or possible traffic or earth loads.
