    The invention relates to a height-adjustable shaft ring element comprising an upper part and a lower part, the upper part being arranged above the lower part, the upper part having at least a first support element and the lower part having at least a second support element, the first support element interacting with the second support element, especially cooperates directly.
    Numerous shaft installations are still being built in street bodies. The surface heights of their covers, i.e. of the lampholders including lids should, if possible, not be above and only slightly below the level of the finished road surface. In the course of time, the road body thickens; Weather, high temperature differences and the traffic volume have an unpredictable impact on the road and also on its built-in components. The mostly different settlements of the roadway and shaft installations are the main cause of shaft covers that are too high or too low, followed by inaccuracies during installation.
    Any manhole cover, the surface of which is above or significantly below the road level, is not only an inconvenience for man and machine, but also represents a potential danger, especially for drivers of single-track vehicles. Driving over multi-lane vehicles with shaft covers that are too high or too low triggers sudden inclinations of the vehicle axles, which can have an unfavorable effect on tall vehicles, in curves and on slippery roads. Manhole covers that are not laid or set flush with the road surface cause much more noise than flush covers and are often the reason for risky evasive maneuvers. When driving over or over, high thrust and pressure forces often act on exposed edges of the roadway or shaft, which in the long run leads to their damage.
    In the usual shaft construction in this country, the surface heights of the manhole covers are achieved after measuring the depth of the sole by a certain combination of manhole rings, which are available in different heights; in the fine area, you can still touch up with leveling mortar. The surface height of such shaft constructions is practically unchangeable after their completion. The previous design of shaft installations in road bodies does not provide for the possibility of precisely regulating their surface height.
    In the course of a renovation of a street with manhole installations, it is therefore often difficult to change the surface heights of the manhole covers, which are no longer corresponding, or to adapt them to the new road surface; in the case of large deviations, excavation work must be carried out in order to be able to replace manhole rings; smaller differences are tolerated.
    When building a new road with manhole internals, the manhole covers are generally set slightly below the level of the finished carriageway in order to take account of the fact that the carriageway has been lowered.
    However, shafts are already known from the prior art, which allow height adjustment. For example, the DD 239234 A1 describes a guided, three-part manhole cover height and slope compensation ring, which consists of three conically arranged rings, the middle ring being of different thicknesses in the middle ring thickness and used for height adjustment, the three rings being evenly arranged around the periphery Have plug holes and are rotatably supported against each other around the vertical axis with the aid of steel mandrels that are inserted into the plug holes, whereby any multi-axis gradient of the shaft cover to the road surface can be set.
    Height-adjustable manhole covers are known, for example, from DE 202 04 332 U1 or DE 10 2015 002 753 A.
    The KR 100925258 B1 describes a height-adjustable shaft structure with which the height of the top of a shaft cover can be adjusted according to the height of the road surface. This includes an upper shaft bracket, a lower shaft bracket and a block element. On the outer periphery of the block element, a spiral toothing is formed, which interacts with a corresponding toothing of the shaft holder.
    The present invention has for its object to provide a height-adjustable shaft ring element that is easy to use.
    The object of the invention is achieved in the aforementioned chess ring element in that the first support element is formed as a series of first tubular jacket sections with a section height in the axial direction, the section heights of two in a circumferential direction immediately following first tubular jacket sections in the The circumferential direction becomes smaller, and the second support element is formed by a sequence of second tubular casing sections with a section height in the axial direction, the section heights of two second tubular casing sections immediately following one another in the circumferential direction becoming larger in the circumferential direction.
    The advantage here is that with the tube mat sections an "inclined plane" can be formed, which is divided into individual intermediate steps, so that the upper part is again in a secure support after each small twisting step. The rotation of the upper part relative to the lower part can thus be divided into several steps without the upper part having to be secured again after a first partial rotation. In addition, the change in height caused by a twisting step can be set relatively finely by means of the number of pipe jacket sections, as a result of which the accuracy of the height leveling can be improved.
    According to a preferred embodiment variant of the shaft ring element, several of the first and second support elements are arranged distributed over the circumference, with which a further simplification of the height adjustment can be achieved, since the upper part is supported several times over the circumference at the same height in each case.
    For easier adjustability can be further provided according to another embodiment that the number of first and second tubular jacket sections per first support element and per second support element is between 5 and 50.
    According to a further embodiment of the invention it can be provided that transitions between the first and the second tubular jacket sections are bevelled or rounded, so that the respective areas of the upper part can “slide” more easily from a second tubular jacket section to the following second tubular jacket section.
    End faces of the first and second tubular jacket sections can be provided with a surface structure according to an embodiment of the invention, whereby the total contact surface for the upper part can be increased and thus the upper part can be better secured against unwanted twisting.
    For easier assembly of the shaft ring element can be provided according to further embodiments that the lower part is connected to or has a mounting ring and / or that the upper part is connected to or has a cover carrier.
    According to another embodiment variant of the invention, it can preferably be provided that the lower part and / or the upper part at least partially have or have a casing. The penetration of sand, gravel, earth, etc. into the area of the pipe jacket sections can thus be better prevented, so that the function of the height adjustment is still provided even after the shaft ring element has been installed for a long time and often passed over with heavy motor vehicles.
    To reduce the individual components and thus for faster installation can be provided according to one embodiment of the invention that the sheath or sheaths is formed by the mounting ring and / or the cover bracket.
    To make it easier to rotate the upper part relative to the lower part, it can be provided that an outer surface of the casing or casings has a surface roughness Ra according to DIN EN ISO 4287 of at most 25 µm, that is to say is relatively smooth. The frictional resistance between the shaft ring element and, for example, the road body can thus be reduced.
    According to a further embodiment of the shaft ring element, it can also be provided that the sheathing of the lower part is at least partially arranged within the sheathing of the upper part, whereby the shaft ring element can also be better protected against foreign particles penetrating from above into the area of height adjustability.
    The lower part and / or the upper part can have at least one locking element, so that this can be better protected against unintentional rotation, for example as a result of crossings with heavy vehicles.
    Preferably, the at least one locking element is designed as a relatively easy-to-use folding latch or as a locking pin.
    It can further be provided that the locking element has an engagement element for the engagement of a rotating device for rotating the upper part relative to the lower part. This makes it possible to dispense with additional tools, for example for the engagement of a rotary motor, which in particular also makes it easier to readjust as a result of inspection work.
    In order not only to be able to compensate for the height, but also to be able to carry out a comparison with inclinations of the shaft environment, it can be provided according to a further embodiment variant that the lower part and / or the upper part has or have an inclination compensation element that has a set ring plate and has a tilting ring plate arranged concentrically therewith, the stacking ring plate and the tilting ring plate having a plurality of recesses on the body surfaces facing one another.
    Furthermore, the assembly of the shaft ring element on the spot can be simplified if, according to an embodiment of the invention, the lower part and / or the upper part has or have a device for preventing the rotation of the shaft cover during the height adjustment.
    It is further possible that the upper part has a light-reflecting element. With this embodiment variant, it is easier to detect subsequent roadway settings, etc., more easily.
    For a better understanding of the invention, this will be explained in more detail with reference to the following figure.

    As an introduction, it should be noted that in the differently described embodiments, the same parts are provided with the same reference numerals or the same component names, and the disclosures contained in the entire description can be applied analogously to the same parts with the same reference numerals or the same component names. The location information selected in the description, e.g. above, below, on the side, etc., referring to the figure described and illustrated immediately, and if the position is changed, these are to be applied accordingly to the new position.
    All standards that are mentioned in this description relate to the latest version of the application on the filing date.
    1 and 2, a manhole ring element 1 is shown with integrated, permanent height adjustability. The shaft ring element 1 makes it possible to set the shaft surface height very precisely already during the completion of the shaft and immediately before the application of the road surface and, moreover, allows the shaft surface height to be adapted at any time later, if necessary, to changed circumstances, such as the settlement Shaft works or the lane area around the shaft. It can take over the function of the top shaft (s) (compensation) rings (s) and can also be subsequently exchanged for these (s); for example in the course of a renovation.
    The shaft ring element 1 preferably consists of only a few individual parts, is simple to manufacture and easy to install.
    The manhole ring element 1 comprises an upper part 2 and a lower part 3, the upper part 2 being arranged above the lower part 3. The height is adjusted by rotating the (unlocked) upper part 2 on the supporting lower part 3, coaxially to the latter, with an open shaft using a suitable tool. For this purpose, the upper part 2 has at least one first support element and the lower part 3 has at least one second support element, the first support element interacting with the second support element, in particular interacting directly. For the most frequently constructed manholes with an outer diameter of around 80 cm, the setting range can be, for example, over a decimeter, with larger diameters the setting range can also be increased. This information is only of an exemplary nature.
    The shaft ring element is preferably at least approximately largely maintenance and wear-free.
    The installation of the height-adjustable shaft ring element 1 also makes it possible to use models of the most varied types and designs or from different manufacturers as the uppermost shaft end elements, provided that these, as previously, correspond to certain standards.
    For the height adjustability it is provided that the first support element of the upper part 2 is formed in a circumferential direction 4 as by a sequence of first tubular jacket sections 5 with a section height 6 in the axial direction 7, with the section heights 6 of two each in the circumferential direction 4 immediately successive first tubular jacket sections 5 (also referred to as tubular jacket segments) becomes smaller in the circumferential direction, as can be seen from FIGS. 1 and 2.
    Furthermore, the second support element in the circumferential direction 4 is formed by a sequence of second tubular jacket sections 8 (also referred to as tubular jacket segments) with a section height 9 in the axial direction 7, the section heights 9 of two second tubular jacket sections immediately following one another in the circumferential direction 4 8 becomes larger in the circumferential direction 4, as can also be seen from FIGS. 1 and 2.
    The first and second tubular jacket sections 5, 8 each extend only over a partial area of the full (circular) circumference of the shaft ring element 1. For example, they can extend over an angular range between 1 ° and 30 °, in particular between 1 ° and 20 ° , extend. All tubular jacket sections 5, 8 preferably have the same width in the circumferential direction 4.
    All tubular jacket sections 5 and / or tubular jacket sections 8 preferably have the same width in the radial direction, i. H. an equal wall thickness, on. Depending on the type and size of the design of the shaft ring element 1, this can be, for example, between 2 cm and 10 cm.
    It should be mentioned that regardless of the type and size of the design of the shaft ring element 1, in the respective individual contact surfaces of the tubular jacket sections 5 and / or tubular jacket sections 8 practically the entire wall thickness and thus preferably a large part of the total wall thickness of the entire component for load and power transmission can be used, which in addition to the generally high load-bearing capacity also allows or favors small widths in the circumferential direction of these surfaces and thus a higher number of gradations. This makes it possible for the level compensation to be carried out with greater accuracy.
    In other words, the shaft ring element 1 has an annular body as the lower part 3 with a plurality of obliquely arranged or extending casing body recesses and an annular body, the lower casing body recesses of which are designed to be complementary to those of the lower part 3, as the upper part 2 or consists of it.
    Due to the construction, which preferably provides relatively large dimensions, and in particular as flat as possible, support surfaces for load and power transmission between the movable upper part 2 and the non-movable lower part 3, safe operation is also possible with high traffic volumes and with high loads, guaranteed by heavy vehicles.
    When using the height-adjustable shaft ring element 1 in the course of a new road construction with shaft internals, there is no need to intentionally lower the shaft surfaces, since an adjustment need only be made if necessary. This increases driving comfort and safety from the outset, and both the shafts and the adjacent lane area are significantly less stressed than would be the case with more or less small but still tolerable height differences between the road surface and shaft surface .
    The first support element is preferably complementary to the second support element. This means that in the zero position, i.e. with zero height compensation, the sum of the section heights 6, 9 of the first and second tubular jacket sections 5, 8 is the same size for each pair of first and second tubular jacket sections 5, 8, as is particularly evident from FIG 2 can be seen.
    According to an embodiment variant of the shaft ring element 1, a plurality of first support elements are preferably arranged on the upper part 2 and, accordingly, a plurality of second support elements are arranged on the lower part 3. For example, three such first receiving elements and three second receiving elements can be arranged as shown in FIG. 1. Generally, between 2 and 8 first receiving elements and between 2 and 8 second receiving elements can be formed, the number of first receiving elements corresponding to the number of second receiving elements.
    The plurality of first and second receiving elements are preferably arranged symmetrically distributed over the circumference of the upper part 2 and the lower part 3. It is further preferred if the plurality of first receiving elements each connect directly to one another and if the plurality of second receiving elements likewise each connect directly to one another. However, there is the possibility that distances are formed between the first and between the second receiving elements.
    In the embodiment variant of the shaft ring element 1 shown in FIGS. 1 and 2, the first and second support elements each have 20 first and second tubular jacket sections 5, 8. In general, the first and second support elements can each have between 5 and 50 first and second tubular jacket sections 5, 8. The number of first and second tubular jacket sections can be selected depending on the diameter of the shaft ring element 1 and the desired step height between the tubular jacket sections 5, 8.
    The transitions between the first and second tubular jacket sections 5, 8 can each be stepped. According to another embodiment variant of the shaft ring element 1, these transitions can be chamfered (chamfered) or rounded, as can be seen from FIGS. 1 and 2.
    The upper part 2 and / or the lower part 3 is / are preferably formed in one piece. For example, they can consist of concrete, a metallic material, etc.
    The lower part 3 is preferably connected to a mounting ring 10 or integrally formed therewith. With this mounting ring 10, the lower part 3 can be connected to a further, underneath shaft structure 11, for example further shaft rings, for example by means of clamping, screwing or similar methods. The connection can be fixed. If necessary, it can also be designed to be tiltable. With the inclinable design, a simple possibility can be created in order to be able to compensate for an axis error or an inclination of the shaft in relation to the roadway level already at the mounting ring 10. For example, several (ideally three) radially distributed recesses can be provided on the underside of the mounting ring 10 in order to be able to effect a plane correction with wedges and / or other spacers which are pushed into the recesses from the inside of the shaft. The resulting gaps between the shaft and the mounting ring 10 can be filled, for example with a mortar.
    The diameter and the geometry of the mounting ring 10 per se can be adapted to the shaft structure 11 underneath.
    The upper part 3 can be fixedly or also rotatably connected to an attached, in particular ring-plate-shaped, cover carrier 12 (for example for a manhole cover) or can be formed integrally therewith. If necessary, the upper part 3 itself can be designed as a cover-bearing shaft closure element.
    The upper part 2 lies with the contact surfaces, i.e. the end faces, the pipe jacket sections 5 on the respective contact surfaces, i.e. End faces, the pipe jacket sections 8 of the lower part 3.
    The upper part 2 can be connected to the lower part 3. Depending on the position relative to each other, the upper part 2 and the lower part 3 connected thereto can form a unit with a variable overall height in the form of a more or less complete pipe section.
    The simple height adjustment by a rotational displacement of the upper part 2 is favored by the shape of the load and force-transmitting contact surfaces (= end faces of the tubular jacket sections 5, 8) of the upper part 2 and lower part 3, which each have different cross-sectional heights in their radially distributed position areas - or have a descending order. These contact surfaces of the stepped position planes can each have smooth surfaces. According to an embodiment variant of the shaft ring element 1, however, it can also be provided that the cooperating end faces of the first and second tubular jacket sections 5, 8 are provided with a surface structure. This surface structuring can, for example, only have surfaces that are profiled in the direction of movement and / or complementarily, flat and horizontal, or inclined surfaces.
    This surface structuring can, for example, have a complementary profiling of the interacting end faces which runs in the circular circumferential direction 4, which enables improved centering, or else a complementary profiling which runs in the radial direction and which can lock an adjustment.
    Instead of or in addition to the possible profiles in the circumferential and radial directions, identical inclinations of the entire end faces in the direction of or against the shaft axis (= axial direction 7) are possible for the purpose of improved centering. A uniform inclination of these entire cooperating end faces against the vertical along their circular direction of movement in such a way that the outer edges or transitions of the adjacent tubular jacket sections 5, 8 have an acute-angled cross-section can support the entire upper part 2 on individual inclined (part) planes of the lower part 3 and thus, depending on the steepness of the individual support surfaces, cause its more or less effective locking or stabilization by gravity and also by loads.
    Designs with complementarily designed profiles of the support surfaces in the radial direction and also those with support surfaces inclined at an acute angle in the circumferential direction 4 relative to the vertical downward require a raising of the upper part 2 and are corresponding to the profile shape or the individual gradient of the support surfaces mainly advantageous for small shafts and also for slide fittings.
    The surface structure can have surfaces which are inclined by up to +/- 20 ° with respect to the shaft axis. Furthermore, it can have surfaces which are inclined up to −30 ° against the vertical in the circumferential direction 4. These inclinations are preferably used in smaller road installations such. B. water slides applied.
    The surface roughness Ra according to DIN EN ISO 4287 of these end faces of the tubular jacket sections 5, 8 can be between 1 μm and 50 μm.
    The gradation of the tubular jacket sections 5, 8 allows a gradual rotation of the upper part 2 about its central axis (in the axial direction 7), lying on the lower part 3 without having to lift it beforehand, i.e. solely by an effective rotation with, depending on the number of steps (= number of pipe jacket sections 5, 8) and step height (= section height 6, 9), more or less, briefly more or less increased torque, the upper part 2 together with its Superstructures and attachments.
    Locking (and fixing) the height adjustment (ie the relative position of the upper part 2 to the lower part 3) can be done easily and quickly according to one embodiment of the shaft ring element 1 with at least one locking element, in particular a folding latch 13 and / or a movable locking pin or extendable latches or extendable rails or similar devices. To illustrate this embodiment variant, three folding latches 13 are shown in FIGS. 1 and 2. However, this number should not be understood as limiting. Fewer or more locking elements can also be arranged.
    Preferably, the folding latch 13 are pivotally attached to the upper part 2 (or in general the at least one locking element is fastened to the upper part) and, in the locked position, engage behind the lower part 3 on the inside thereof. However, there is also the possibility that, in addition or as an alternative, at least one locking element is attached to the lower part 3.
    The folding latches 13 can have a trapezoidal shape with an angled portion on the short side.
    As an alternative to this arrangement, there is also the possibility that the locking elements of the upper part 2 interact with the further shaft construction located on the upper part 2, in particular the cover support 12. For this purpose, for example, the cover carrier 12 can have a recess 14 in a ring web 15 per folding latch, into which the respective folding latch 13 can engage in a locking or latching manner.
    Furthermore, the at least one locking element according to another embodiment variant can also be fastened to one of the components of the shaft arranged above the upper part 2, for example the cover support 12, and pivoted downward for locking.
    However, the at least one locking element can also be completely removable from the elements of the shaft, that is to say in particular the upper part 2 or the cover carrier 12, that is to say it cannot be fixedly mounted on one of the components of the shaft. For example, the at least one locking element can also be designed as a clamp or clip.
    For locking the height position of the upper part 2, corresponding recesses 16 or receiving devices can be provided on the lower part 3, into which the at least one locking element can engage or engage, whereby both the upper part 2 and the lower part 3 can be combined and centered. These recesses 16 can be, for example, bores in the tubular jacket sections 8, wherein each tubular jacket section 8 can have such a bore.
    It can further be provided that the outer, engaging ends 17 of locking bodies, in particular the latch bolt 13 or bolts, are conical, those of rod-shaped or rail-shaped bolts have corresponding circumferential bevels or a decreasing profile cross section in order to provide a guided, to achieve angular symmetrical centering, or an exact and play-free engagement in the setting positions.
    The movable locking element (s) and connecting parts or locking body of the upper part 2 or lower part 3 can by mounting measures, such as. Screws 18, which can effectively and permanently prevent their movement, are secured to the respective add-on part and can also be used, for example, between the upper part 2 and the cover support 12, provided that these parts have corresponding recesses.
    According to another embodiment variant of the shaft ring element 1, it can be provided that the locking element has an engagement element for the engagement of a rotating device for rotating the upper part 2 relative to the lower part 3. For this purpose, the movable part of the locking element or the movable parts of the locking elements upper part 2 can be mounted on the cover carrier 12 or in between. The engagement element for receiving a suitable tool (not shown) for adjusting the surface height of the shaft after completion of the road surface, i.e. for rotating the upper part 2, there can be, for example, a recess or an opening 19 in the locking element, for example folding latch 13.
    Alternatively or in addition to this, further engagement elements for height adjustment of the upper part 2 can be arranged, for example in the form of horizontal bores in the radial direction in the inner upper edge region of the upper part 2 or of the cover support 12 or similar recesses, which can each also serve as a tool holder.
    According to another embodiment variant of the shaft ring element 1, it can be provided that the lower part 3 at least partially has a casing 20 and / or the upper part 3 at least partially has a casing 21. At least one of the two jackets 20, 21, preferably both, can be made of sheet metal or plastic. The penetration of earth, sand, asphalt or concrete into the shaft ring element 1 or into the shaft can thus be better prevented.
    A centering of the upper part 2 and lower part 3 can also be achieved with the jackets 20, 21. In addition, it can be achieved that the upper part 2 is guided coaxially to the lower part 3 during its adjustment.
    Preferably, the two sheaths 20, 21 are formed like an apron.
    The upper casing 21 of the upper part 2 can slide sleeve-like downward over the lower casing 20 of the lower part 3 during the height adjustment, so that according to a further embodiment variant of the shaft ring element 1, the casing 20 of the lower part 3 at least partially within the casing 21 of the upper part 2 is arranged.
    According to a further embodiment, an outer surface 22 of the casing 21 of the upper part 2 and / or an outer surface 23 of the casing 20 of the lower part 3 can have a surface roughness according to Ra according to DIN EN ISO 4287 of at most 25 µm, in particular between 1 µm and 25 µm, in order to keep the frictional resistance between it and the ground surrounding it, for example a road body 24, as low as possible during the adjustment.
    The casing 21 of the upper part 2 preferably extends at least approximately, in particular precisely, up to the surface of the manhole cover.
    According to a further embodiment of the shaft ring element 1, the upper outer edge or the casing 21 of the upper part 2 and / or the upper part 2 can be provided or coated with a light-reflecting material which, in the event of a lowering of the adjacent (roadway) Area serves as an indicator.
    The sheathing 21 of the upper part 2 can also be used for fastening an inserted manhole cover, the sheathing 20 of the lower part 3 also for connecting it to the underlying shaft construction 11.
    Preferably, a gap between the upper casing 21 and the adjacent area of the road body 24 or the floor is closed after installation or after adjustment with a suitable sealant.
    According to a further embodiment variant, it can be provided that the casing 20 is formed by the mounting ring 10 and / or the casing 21 by the cover carrier 12.
    As an additional embodiment variant, it can be provided that the upper part 2 (or the entire construction or the shaft ring element 1) has an inclination device for adapting the plane to the road surface.
    Such a device is preferably positioned between the upper part 2 and the manhole cover to be used and can (essentially) consist of two load and force-transmitting, equally dimensioned disk-shaped pipe sections or ring plates which, in the zero position, lie flat on one another concentrically and over the entire surface and which can be deliberately spread apart by inserting wedges at several, radially distributed positions.
    A preferred exemplary embodiment of such an inclination compensation element 25 (as an additional shaft ring element) is shown in FIG. 3.
    A stacking ring plate 26, which is mounted or fastened concentrically on the upper part 2 or the cover carrier 12 or on the mounting ring plate 10 (all shown in FIG. 1) or on the existing shaft construction, has the shape of a disk-shaped tube section, the outer diameter of which in the axial direction 7 increases towards the top. The set ring plate 26 can also be integrated in the upper part 2 or in the cover carrier 12 or in the mounting ring plate 10. An inclination 27 of the outer, conically inclined jacket wall of the set ring plate 26 can be selected depending on its body height in the axial direction 7 and / or as a function of the greatest possible inclination angle of the inclination compensation element 25. For example, the slope 27, i.e. the angle of inclination is between 5 ° and 25 ° from the vertical to the shaft axis in the axial direction 7.
    The beveling is intended to prevent the circular cross-section of the inclination compensation element 25, which is circular in the zero position, from increasing as an ellipse after a plane adjustment in the inclined position.
    A tilt ring plate 28, preferably of the same dimensions as the stacking ring plate 26, but with an outside diameter decreasing upwards in the direction of the shaft axis 7, which can also be a component of the cover support 12 or of the lower part 3, is concentric, even in the zero position of the inclination compensation element 25 and over the entire surface, in mirror image in cross section on the stacking ring plate 26.
    The stacking ring plate 26 and the tilt ring plate 28, which preferably consist of reinforced concrete or a metallic material, are surrounded by a tubular section-shaped encircling ring 29 over their outer circumference. The surrounding ring has a height which is not greater than the sum of the heights of the tilt ring plate 28 and the set ring plate 26 (in each case in the axial direction 7), but preferably corresponds in height to the total height of the two ring plate parts in the zero position. The encircling ring 29 can be made of iron or steel, for example. The wall thickness of this encircling ring 29 and the radial width of the set ring plate 26 and / or the tilt ring plate 28 together result in the total radial width of the inclination compensation element 25, the radial width of the set ring plate 26 and / or the tilt ring plate 28 being at least twice as large as that of the encircling ring 29.
    On the inside of the encircling ring 29, a plurality of threaded bolts 30 (for example made of iron or steel), which are uniformly distributed over the circumference and positioned at half the height of the jacket, are preferably welded in the radial direction and normal to the shaft axis in the axial direction 7 point towards the center of the shaft and which are no longer than the radial width of the stacking ring plate 26 and / or the tilting ring plate 28.
    The stacking ring plate 26 and the inclining ring plate 28 have on the mutually facing body surfaces a plurality of recesses 31 and 32, preferably of the same size and preferably of mirror-symmetrical cross-section with respect to their plane of contact, which together produce the minimally enlarged cross-sectional shape of the threaded bolts 30 and in the same Number, at the same distance and in the same radial position as these are arranged.
    This makes it possible to use the surrounding ring 29 by means of its radially attached threaded bolts 30, which are placed in the recesses 31, precisely, radially stabilized and concentrically between the set ring plate 26 and the tilt ring plate 28.
    Further recesses or recesses 33 of the top of the set ring plate 26, and just as many recesses 34 of the bottom of the tilt ring plate 28, which in relation to those of the set ring plate 26 in their entirety, preferably in a mirror-symmetrical manner to the plane support or contact plane of the set ring plate 26 and tilt ring plate 28 are designed in the zero position and ax head sections are similar in their respective paired overall shape, can be located in the area around the threaded bolts 30, mostly in the inner area, ie in the direction of the center of the shaft.
    These recesses 33 and 34 all have a continuously tapering cross-section towards the outside of the shaft and make it possible, each in cooperation, partially complementary to the overall shape of the pairs of recesses 33 and 34 designed ax head-like wedge bodies or insertion wedges 35, which in their radial direction of thrust completely and the minimally enlarged diameter of the threaded bolts 30 are drilled through, from the inside of the shaft all the way onto the threaded bolts 30, in order to position these insertion wedges 35 between the setting ring plate 26 and the tilting ring plate 28 in the zero position and by means of screw nuts 36 which are on the threaded bolts 29 screwed on to secure.
    If, after securing an insertion wedge 35, a screw nut 36 is further screwed onto a threaded bolt 30, then it pushes the insertion wedge 35, which is preferably made of metallic material, between the set ring plate 26 and the tilt ring plate 28 in the direction of the encircling ring 29, which, due to the at least partially complementary Form of insertion wedge 35 and recesses 33 and 34, spreading apart the ring plate parts 26 and 28 in their radial area around the threaded bolt 30.
    The preferred embodiment with three wedge bodies or insertion wedges 35 distributed uniformly over the circumference enables an exact and stable plane adjustment.
    The settings can be secured by lock nuts 37.
    According to another embodiment variant, it can also be provided that the upper part 2 (the entire construction or the shaft ring element 1) has a device for preventing the (co) rotation of the shaft cover during an adjustment process.
    Such a device is preferably positioned directly under the manhole cover and is useful if a (co) rotation of the manhole cover during the adjustment is not desired or is to be difficult, e.g. B. with square covers.
    Such an element for the rotational stabilization of manhole covers essentially consists of two load and force-transmitting, concentric ring plates, which are coaxial in the shaft direction (in the axial direction) by one or more profiling (s) and / or chamfer (s) and / or a casing 7) are rotatably supported on one another and coaxially against one another, in that there are guided or loose round bodies between their mutually facing body surfaces.
    FIG. 4 shows a section from a possible embodiment of a torsion stabilization element 38 as an additional shaft ring element.
    A base ring plate 39 in the form of a tubular disk section has a flat, channel-like depression 40 in the surface over its entire upper side of the body. A roller ring 41 (for example made of iron or steel) is inserted into this circular recess 40, which preferably has a flat and preferably relatively smooth surface (Ra according to DIN EN ISO 4287 = 10 µm - 100 µm), the total height of which is greater than the height of the Depression 40 (in the axial direction 7), preferably between 5% and 50% larger than the height of the depression 40.
    The roller ring 41 shown in FIG. 5 preferably consists of three to thirty, preferably identically dimensioned, circular cylindrical rollers 42 distributed radially over the entire circumference. The rollers 42 can be formed on both sides with conical ends 43, which on the outside of the ring an outer perforated band ring 44 and on the inside of the ring engage in an inner perforated band ring 45 in order to maintain their radial alignment and their spacing from one another with each rotation of the upper part 2 together with its possible structures.
    The diameter of the outer perforated band ring 44 is larger than that of the inner perforated band ring 45 by one roller length in the radial direction of the roller ring 41. Both perforated band rings 44, 45 preferably have the same number of perforated holes 46 (or recesses or openings) at half the jacket height on, which corresponds to the amount of rollers 42, and are firmly connected to one another by webs 47 distributed radially between the rollers 42.
    The cross-sectional heights (in the axial direction 7) of the perforated band rings 44 and 45 and the webs 47 are lower than those of the rollers 42, preferably between 5% and 75% lower than those of the rollers 42.
    An upper support ring plate 48 (FIG. 4) has an outer diameter of the same size or greater than that of the base ring plate 39, but is preferably provided with a conical bevel 49 which runs obliquely downwards and outwards and then lies like a cover on the other Share.
    When the upper part 2 is adjusted and rotated upward about the shaft axis, the rotational stabilization element 38 converts the rotary movement under the shaft cover into a vertical thrust force, whereby the shaft cover is raised without rotating itself. When the lowering is deliberately lowered, or when the upper part 2 is adjusted and rotated downward about the shaft axis, gravity or a reinforcement of this by loading the shaft cover causes the shaft cover to be lowered to the desired setting depth.
    The base ring plate 39 and / or the entire anti-rotation element 38 can also be built or integrated in the upper part 2 or in the cover support 12 or in the inclination compensation element 25.
    The manhole cover can be round or square.
    [0111] If the given installation height is very limited, the shaft ring element 1, which is adjustable in height, can be designed as the top shaft closure part itself as a cover support.
    The exemplary embodiments show or describe possible design variants of the shaft ring element 1, it being noted at this point that combinations of the individual design variants with one another are also possible.
    Finally, for the sake of order, it should be pointed out that, for a better understanding of the structure of the shaft ring element 1, this or its components are not necessarily shown to scale.
