Definitions

  • the invention relates to a device according to the preamble of claim 1 and a transmission device and a shaft according to claims 14 and 15.
  • a shaft In wastewater technology and wherever a shaft is needed for a lower substructure (e.g. the manhole of a grease separator), at least the manhole cover and the uppermost manhole element must be installed at a fixed distance relative to the substructure.
  • the manhole cover can be walked on or even driven over.
  • shafts typically inspection shafts
  • the manhole element must be held relatively firmly with the manhole cover so that the installation can be carried out without problems. In practice, therefore, the shaft element is mostly rigidly supported against the substructure.
  • adjustment elements are used to adjust the manhole cover exactly to the ground level or to readjust it when placing the soil. Damage to the substructure can result when walking or driving over it.
  • the invention has for its object to provide a device of the type mentioned and a transmission device or a shaft to a substructure, with which damage to the substructure can be avoided in spite of pressure forces exerted when walking or driving over.
  • the transmission device keeps the shaft element in the stable position necessary for the installation as well as later when walking and driving over. However, if a force that is harmful to the substructure occurs, the transmission device decouples the shaft element from the substructure without relinquishing the holder of the shaft element. This protects the substructure from damage. A stable mounting and support of the shaft element is nevertheless guaranteed under forces that are harmless to the substructure.
  • the clamping ring forms, so to speak, a coupling that yields under overload between the shaft element and the substructure, but even after giving in to protect the substructure, a sufficient holding force for the shaft element is still maintained.
  • the shaft according to claim 15 is ultimately predestined for those applications in which protection is required for the substructure.
  • the upper part of the shaft element adapts well to a sinking floor level, in which the loads rolling over it push the projecting shaft element back onto the level without the substructure being damaged or the position being changed.
  • the frictional connection according to claim 2 can be made with structurally simple means and is reliably maintained even over a long service life. It can be exactly according to claim 3 adjust to the force that is still acceptable for the substructure.
  • the transmission device represents a clutch that can be released in the event of an overload, it can also be used particularly expediently for adjusting the height or leveling the shaft element or the shaft cover. This means that when installing the shaft, the required height and orientation of the shaft element are set by means of the transmission device before the soil around the shaft is filled in and, if necessary, the ground level is established. For leveling, the frictional connection can be temporarily released and restored after leveling. However, it is also conceivable to maintain the frictional connection and to actuate the transmission device with other means for leveling.
  • the embodiment according to claim 5 has proven particularly useful in practice because a clamping ring can be produced simply and inexpensively and can be easily attached to any position.
  • the feature of claim 6 is also important because the height adjustment elements allow the position of the clamping ring to change relative to the support and thus the leveling or adjustment of the shaft element or shaft cover is easily possible without the clamping ring having to be released. For a rough setting, however, it is advisable to roughly adjust and tighten the clamping ring on the shaft element. It would also be conceivable to fix the adjusting elements on the support and put on the clamping ring.
  • the embodiment according to claim 7 is also expedient, in which the clamping ring rigidly supports the shaft element, itself, however, on the support or the substructure with the frictional connection, optionally combined with a positive connection, is defined such that it yields when the force limit is reached Shaft element permitted.
  • the clamping ring can be used with this Embodiment to be pre-assembled on the support or on the base.
  • the shaft element is now only placed on top of it, if necessary via the adjustment elements which permit height adjustment.
  • the embodiment according to claim 8 is useful.
  • the reducing ring ensures that the clamping ring does not have to compensate for large differences in diameter which may be detrimental to its function.
  • the embodiment according to claim 9 is structurally simple and reliable.
  • the ring segments can be attached to the shaft element separately from the side and joined to form the tension ring and clamped to the shaft element.
  • the division of the clamping ring into several segments has the advantage of being easy to manufacture and of individual adaptation of the clamping ring to the circumference of the shaft element.
  • the tension ring does not necessarily have to be round; Different geometrical configurations are conceivable, depending on the circumference of the shaft element or the support.
  • the multi-part structure also has the advantage of a uniform pressure force on the shaft element and a large-area force transmission without local load concentration which may be harmful to the shaft element.
  • the short segments are easier to transport.
  • the clamping ring is designed from the outset for the fine height adjustment.
  • the feature of claim 11 is important because the recordings are thus close to the areas of the clamping ring in which it is pressed particularly firmly against the shaft element. This results in stable support even under high forces.
  • the embodiment according to claim 12 is important. Since the holding force for the shaft element is transmitted via the clamping surface, structuring leads to an improved holding effect. If necessary, the structuring by means of the frictional connection also achieves a slight form fit because the ribs are pressed into the shaft element. This positive connection supports the holding effect of the clamping ring.
  • the embodiments according to claim 13 are inexpensive and lightweight.
  • the ring segments can be the same. If the clamping ring is composed of a large number of such ring segments, any diameter of the shaft element can be covered with one ring segment type.
  • a shaft S to a substructure U can be seen in FIG. 1, the substructure having an annular part which is either anchored in the ground or on an underlying object, e.g. a container 2, for example a fat separator or a sewage system, is supported.
  • a container 2 for example a fat separator or a sewage system
  • FIG. 1 shows the concept of a relatively deep shaft.
  • a top piece 3 is placed and fixed with an annular clamp 4.
  • the attachment piece 3 tapers upwards and has at the upper end a circumferential flange forming a support 5 with depressions 6 or a circumferential groove.
  • an approximately tubular shaft element 7 which has a seat 8 for a shaft cover 9.
  • the manhole cover 9 is to be adjusted flush with the floor level N and must be walkable or, if necessary, passable and therefore kept stable.
  • a support A is provided for the shaft element 7, which is formed in the left half of Figure 1 by the top piece 3 and a transmission device B.
  • the transmission device B consists of a clamping ring 11 (see FIG. 2), which is composed of several, in the present case three, segments and rests with a clamping surface 12 on the outer peripheral wall 10 of the shaft element 7.
  • the ring segments R are connected to each other with clamping elements 14, for example clamping screws, and are tightened with selectable pressure on the shaft element 7, so that there is a frictional connection between the clamping ring 11 and the shaft element 7, thanks to which the shaft element 7 in the set height position relative to the substructure U is held.
  • the clamping surface 12 of the clamping ring can be provided with a structure (13), for example with circumferential ribs, which under the clamping force penetrate into the outer peripheral wall 10 of the Press in shaft element 7.
  • the clamping ring 11 is composed of a plurality of ring segments R, in the present case three ring segments R which are identical to one another.
  • Each ring segment R has at least one receptacle 15 for a height adjustment element 17, in the present case a height adjustment screw.
  • Locking nuts 16 are fixed in the receptacles 15, in which the height adjustment elements 17 can be screwed for fine adjustment of the position of the manhole cover 9. With their lower ends, the height adjustment elements 17 are supported in the recesses 6 of the top piece 3.
  • the attachment piece 3 is first fixed on the substructure U with the annular clamp 4. Then the clamping ring 11 is roughly fixed on the shaft element 7. The shaft element 7 is then placed on the support 5 with the clamping ring 11. Then the height of the shaft element 7 is roughly adjusted before the clamping ring 11 is tightened with a predetermined clamping force. The fine adjustment is then carried out by means of the height adjustment elements 17. Then the soil is filled in and the ground level N is built. When the manhole cover 9 is walked on or passed over, a force is exerted on the manhole element 7 in the direction of an arrow 18.
  • the selectable frictional connection of the clamping ring 11 ensures that only a limited value of the force is transmitted to the substructure U, which is still harmless to the substructure. If the acting force exceeds this limit value, then the shaft element 7 slides down relative to the clamping ring 11, whereby it is still held securely. However, the substructure is secured against damage.
  • a seal 20 indicated by dashed lines can be attached to the attachment piece 3.
  • the lower part of the shaft can be built from several stacked top pieces 3.
  • the uppermost shaft element 7 is then placed on the uppermost attachment piece in the aforementioned manner by means of the clamping ring 11.
  • each ring segment R has two ends 21, 22.
  • the receptacle 15 for the adjusting element 17 is not set in the middle, but closer to the one end 22, because in the joint areas between the mutually facing ends 21, 22 the greatest contact pressure may be exerted the shaft element 7 is present and it is expedient to transmit the pressure down as close as possible to the parting line.
  • the ring segments R are expediently formed from plastic, and reinforced plastic can also be used.
  • the structuring 13 of the clamping surface 12 of the clamping ring 11 can also be designed in a different way in such a way that a combined positive and positive connection results on the shaft element.
