Abstract

The invention relates to a method for producing a manhole element, particularly a manhole ring (4), from concrete or reinforced concrete, comprising an upper edge (4c) and a lower edge (4b), whereby the upper and lower edges (4c; 4b) are designed for centrally engaging inside the edges (4b; 4c) of adjacent manhole rings (4). One edge (4c) has spacing areas (4d), which are distributed along the periphery and which, in the direction of the longitudinal axis (4a), jut out or are set back with regard to the remaining adjacent surrounding edge area. The lower edge (4b) of a fixed lower sleeve (3) and the upper edge (4c) of a lowerable upper sleeve (1d; 1e) of a manhole ring finisher (1), said upper sleeve being able to swivel in an alternating manner about the axis of symmetry of the manhole element, are formed by compacting the concrete located inside a manhole ring mold. The spacing areas (4d) are provided on the upper edge (4c) formed by the upper sleeve (1d; 1e), and the upper sleeve (1d; 1e) is subdivided into two different areas (1e and 1d), the first (1e) of which being designed so that it cannot swivel with regard to the upper edge (4c) and being provided for forming the spacing areas (4d). The second area (1d), together with the first area (1e), is arranged so that it can be lowered and can swivel in an alternating manner with regard to the first area. The upper edge (4c) is formed by the separately constructed upper sleeve (1d; 1e) in such a manner that the spacing areas (4d) are formed by the non-swiveling first area (1e) of the upper sleeve (1d; 1e), and the remaining upper edge (4e) is formed by the second area (1d) of the upper sleeve (1d; 1e), said second area being able to swivel in an alternating manner.

TECHNISCHE GEBIETTECHNICAL AREA
Die Erfindung betrifft ein Verfahren nach dem Oberbegriff des Patentanspruchs 1 und eine Obermuffe zur Verwendung bei dem erfindungsgemäßen Verfahren und einen nach dem erfindungsgemäßen Verfahren mit der neuen Obermuffe hergestellten Schachtring.The invention relates to a method according to the preamble of patent claim 1 and an upper sleeve for use in the method according to the invention and a manhole ring produced by the method according to the invention with the new upper sleeve.
STAND DER TECHNIKSTATE OF THE ART
Es ist ein Schachtring bekannt (EP 0 759 488 AI) , der aus Beton oder Stahlbeton besteht und einen rotationssymmetrischen oberen Rand sowie einen unteren Rand aufweist. Der obere Rand wird bei Schachtringen als Spitzende bezeichnet, der untere Rand als Muffenende. Die oberen und unteren Ränder des bekannten Schachtbauteils sind so geformt, daß im aufgesetzten Zustand zweier benachbarter Schachtbauteile in Umfangsrichtung voneinander abgesetzte Auflagerflächen gebildet werden. Hierzu sind am unteren Rand, also am Muffenende, erhabene Auflagerflächen ausgebildet und zur Auflage auf einer im wesentlichen ringförmigen Auflagerfläche des oberen Randes des zweiten Schachtbauteils geeignet. Der untere Rand hat eine innere Kehle und der obere Rand einen im wesentlichen komplementär zu dieser Kehle ausgebildeten radialen Querschnitt. Im aufeinandergesetzten Zustand zweier Schachtbauteile wird zwischen den beiden Rändern ein Hohl- räum zur Aufnahme einer Dichtung gebildet. Um statisch einwandfreie Verhaltnisse zu erhalten, werden an den Auflagerstellen Dreipunktauflagen gebildet. Diese Dreipunktauflagen sind beim gesamten Schacht über die gesamte Bauhohe inner- halb gemeinsamer vertikaler Ebenen angeordnet.A shaft ring is known (EP 0 759 488 AI), which consists of concrete or reinforced concrete and has a rotationally symmetrical upper edge and a lower edge. The upper edge of shaft rings is referred to as the spigot end, the lower edge as the socket end. The upper and lower edges of the known shaft component are shaped in such a way that in the attached state of two adjacent shaft components, support surfaces which are offset from one another in the circumferential direction are formed. For this purpose, raised bearing surfaces are formed at the lower edge, that is to say at the end of the sleeve, and are suitable for bearing on an essentially annular bearing surface of the upper edge of the second shaft component. The lower edge has an inner throat and the upper edge has a radial cross section which is essentially complementary to this throat. When two shaft components are placed one on top of the other, a hollow formed to accommodate a seal. In order to maintain statically perfect conditions, three-point supports are formed at the support points. These three-point supports are arranged in the entire shaft over the entire height within common vertical levels.
Die Fertigung eines solchen Schachtbauteils erfolgt in der bisher üblichen bekannten Art und Weise: Das Muffenende wird auf einer ortsfesten Untermuffe gebildet, das Spitzen- de von einer Obermuffe, die Teil eines Schachtringfertigers ist und bei der Formung des Spitzendes gleichzeitig um die Langsachse des Schachtrings alternierend hin und her verschwenkt wird und bei dieser alternierenden Verschwenkbewe- gung abgesenkt wird. Die Bildung der erhabenen Auflagerfla- chen kann bisher nur am Muffenende mit einer feststehenden Untermuffe erfolgen. Die Anordnung von Auflagerflachen an der Unterseite, also am Muffenende, erweist sich jedoch als nachteilig, weil die nach unten vorspringenden Auflagerflachen beim Transport der Schachtringe an dieser Stelle be- sonders anfallig gegen Belastungen sind und leicht zerstört werden können. Außerdem ist die Herstellung von Schachtringen mit Auflagerflachen am Muffenende kostspielig, weil hierzu eine große Anzahl von speziell ausgebildeten Untermuffen, die die Formbereiche für die Auflagerflachen auf- weisen müssen und nicht einfach rotationssymmetrisch sind, vorgehalten werden muß. DIE ERFINDUNGSuch a manhole component is manufactured in the previously known manner: the socket end is formed on a stationary lower sleeve, the tip end is formed by an upper sleeve, which is part of a manhole ring manufacturer and alternates around the longitudinal axis of the manhole ring when the pointed end is formed is pivoted back and forth and is lowered during this alternating pivoting movement. Up to now, the raised support surfaces could only be formed at the end of the socket with a fixed lower socket. However, the arrangement of support surfaces on the underside, that is to say at the end of the socket, proves to be disadvantageous because the support surfaces projecting downwards are particularly susceptible to loads at this point when the manhole rings are being transported and can be easily destroyed. In addition, the production of manhole rings with bearing surfaces at the end of the socket is expensive because a large number of specially designed lower sleeves, which must have the shaped areas for the bearing surfaces and are not simply rotationally symmetrical, have to be kept available. THE INVENTION
Ausgehend von diesem Stand der Technik liegt der Erfindung die Aufgabe zugrunde, ein Verfahren der als bekannt voraus- gesetzten Art so auszubilden, daß es die Bildung von Distanzbereichen am oberen Rand, also am Spitzende erlaubt.Proceeding from this prior art, the object of the invention is to develop a method of the type presupposed as known in such a way that it is possible to form distance regions at the upper edge, that is to say at the tip end.
Die Losung dieser Aufgabe erfolgt mit den Merkmalen des Patentanspruchs 1.This problem is solved with the features of claim 1.
Dadurch, daß die Obermuffe nicht mehr einteilig ausgebildet ist, sondern in zwei unterschiedliche Bereiche unterteilt ist, deren erster unverschwenkbar gegenüber dem oberen Rand ausgebildet ist, wahrend der zweite Bereich verschwenkbar bleibt, ergibt sich die Möglichkeit, eine Ausbildung mit einem Spitzende vorzunehmen, das nicht rotationssymmetrisch ist. Vielmehr können die Distanzbereiche in einer anderen Hohe angeordnet sein als der verbleibende übrige umlaufende Rand, und zwar sowohl nach oben vorspringend als auch ge- genuber dem übrigen Rand eingezogen. Bei einem gegenüber dem übrigen Rand zurückspringenden Niveau werden Distanzelemente in die Distanzbereiche eingelegt und bilden dann mit ihren Oberseiten die Auflagerflachen, die am unteren Rand des darüber angeordneten Schachtrings anliegen. KURZBESCHREIBUNG DER ZEICHNUNGSABBILDUNGBecause the upper sleeve is no longer formed in one piece, but is divided into two different areas, the first of which is designed to be non-pivotable relative to the upper edge, while the second area remains pivotable, there is the possibility of carrying out training with a pointed end that does not is rotationally symmetrical. Rather, the spacing areas can be arranged at a different height than the remaining remaining peripheral edge, both projecting upwards and being drawn in relative to the remaining edge. At a level that is set back relative to the rest of the edge, spacer elements are inserted into the spacer areas and then form with their upper sides the support surfaces which abut the lower edge of the shaft ring arranged above them.

BESTER WEG ZUR AUSFÜHRUNG DER ERFINDUNGBEST WAY TO CARRY OUT THE INVENTION
In den Zeichnungen sind gleiche Teile mit den gleichen Bezugszeichen versehen, die sich im Bedarfsfall durch Hoch- striche voneinander unterscheiden.In the drawings, the same parts are provided with the same reference numerals, which differ from one another in the case of needles if necessary.
In Figur 1 ist zum besseren Verständnis des Verfahrens ein Schachtringfertiger 1 mit seinen wesentlichen Teilen dargestellt. Auf einer Untermuffe 3 liegt ein frisch geformter Schachtring 4 mit einer vertikalen Längsachse 4a. Die Untermuffe 3 ist rotationssymmetrisch ausgebildet. Die Untermuffe 3 hat das Muffenende des Schachtrings 4 gebildet.FIG. 1 shows a manhole ring manufacturer 1 with its essential parts for a better understanding of the method. A freshly formed shaft ring 4 with a vertical longitudinal axis 4a lies on a lower sleeve 3. The lower sleeve 3 is rotationally symmetrical. The lower sleeve 3 has formed the sleeve end of the shaft ring 4.
Von dem Schachtring 4 ist ein Spitzendformer abgehoben, der an einer Preßglocke lc befestigt ist. Der Spitzendformer wird als Obermuffe bezeichnet. Oberhalb der Preßglocke lc wird der Formmantel lb zum Absenken für den folgenden Fertigungszyklus bereitgehalten. Am als Spitzende bezeichneten oberen Rand 4c sind gleichmäßig am Umfang verteilt üblicherweise drei Distanzbereiche 4d vorgesehen. Die Auflagerflächen des Distanzbereichs 4d ragen gegenüber dem restlichen, sich anschließenden umlau- fenden Rand 4e vor.From the shaft ring 4 a tip end former is lifted, which is attached to a press bell lc. The tip end former is called the upper sleeve. Above the press bell 1c, the shaped jacket 1b is kept ready for lowering for the following production cycle. At the upper edge 4c, referred to as the tip end, three spacing areas 4d are usually provided evenly distributed over the circumference. The bearing surfaces of the spacing area 4d protrude from the rest of the adjoining peripheral edge 4e.
Die Zeichnungsfiguren 2 bis 6 zeigen, daß die Distanzbereiche 4d unterschiedlich ausgebildet sein können. Üblicherweise sind sie erhaben, wie in den Figuren 2 und 4 bis 6. Bei der Ausführungsform gemäß Figur 3 sind sie abgesenkt. Um aus den abgesenkten Distanzbereichen 4d' Auflager bilden zu können, müssen Einlagestücke eingelegt werden, die über das Niveau des kreisringförmigen Randes 4e nach oben vorstehen .The drawing figures 2 to 6 show that the distance areas 4d can be designed differently. They are usually raised, as in FIGS. 2 and 4 to 6. In the embodiment according to FIG. 3, they are lowered. In order to be able to form supports from the lowered spacing areas 4d ', insert pieces must be inserted which protrude upward above the level of the annular edge 4e.
Es ist möglich, die Auflagerbereiche vollständig aus Beton zu bilden, wie dies in Figur 2 bei 4d dargestellt ist. Es ist aber auch möglich, die Auflagerbereiche zumindest teilweise aus anderen Materialien herzustellen und einzuformen bzw. anzuformen. Bei der Ausführungsform gemäß Figuren 6 und 7 ist der Kern des Auflagerbereichs durch Beton gebildet, der von einer aus Kunststoff bestehenden Kappe 6 umschlossen ist.It is possible to form the support areas entirely from concrete, as shown in FIG. 2 at 4d. However, it is also possible to at least partially produce the support areas from other materials and to mold or to mold them. In the embodiment according to FIGS. 6 and 7, the core of the support area is formed by concrete, which is enclosed by a cap 6 made of plastic.
Das wesentliche Merkmal der Obermuffe besteht darin, daß sie geteilt ausgebildet ist. Der Aufbau ist aus Figur 8 ersichtlich:The main feature of the upper sleeve is that it is split. The structure is shown in Figure 8:
Ein erster Obermuffenbereich le wird über eine nicht genau- er dargestellte Mechanik unverdrehbar an einer vertikalen Stütze 7 gehalten. Innerhalb der Stütze 7 findet sich eine zentrale Welle 8, die alternierend um die Achse 7a nach beiden Seiten verschwenkbar ist. Die innere Stütze 8 ist mit einem korbartigen Element verbunden, welches den zur Bildung des Spitzendes vorgesehenen Profilring 9 trägt. Der erste Obermuffenbereich le, der unverschwenkbar ist, ist über Halter 10 mit dem beim Formen feststehenden Bereich 11 verbunden. Damit erster und zweiter Obermuffenbereich gegeneinander verschwenkbar beweglich sind, sind am ersten Obermuffenbereich kreisbogenförmige Langlöcher lf vorgesehen, welche von den Haltern 10 durchsetzt werden. Auf diese Weise ergibt sich die relative Schwenkbeweglichkeit zwischen dem ersten Obermuffenbereich le und dem zweiten Obermuffenbereich ld.A first upper sleeve area le becomes non-rotatable on a vertical via a mechanism that is not shown in more detail Support 7 held. A central shaft 8 is located within the support 7 and can be pivoted alternately about the axis 7a to both sides. The inner support 8 is connected to a basket-like element which carries the profile ring 9 provided for forming the tip end. The first upper sleeve area le, which cannot be swiveled, is connected via holder 10 to the area 11 which is fixed during molding. So that the first and second upper sleeve areas can be pivoted relative to one another, circular arc-shaped elongated holes 1f are provided on the first upper sleeve area, through which the holders 10 pass. This results in the relative pivoting mobility between the first upper sleeve area le and the second upper sleeve area ld.
In Figur 7 ist dargestellt, daß der unverdrehbare Obermuffenbereich le eine mit Unterdruck beaufschlagbare Aufnahme für eine Kappe 6 aufweist. Auf diese Weise wird die Kappe 6 beim Formen des Spitzendes festgehalten ohne abfallen zu können.In FIG. 7 it is shown that the non-rotatable upper sleeve area le has a receptacle for a cap 6 which can be acted upon by negative pressure. In this way, the cap 6 is held when the tip end is formed without being able to fall off.
In den verschiedenen Schnittdarstellungen gemäß Figur 10 sind unterschiedliche Ausführungen sowohl der Verbindung als auch der Anordnung vom ersten Obermuffenbereich le und zweiten Obermuffenbereich ld dargestellt. Selbstverständlich sind in der Praxis nur jeweils gleiche Ausführungen an einer Obermuffe vorgesehen. Figur A-A zeigt die Form, die zur Bildung von Figur 3 benutzt wird, Figur A'-A' die Form, die zur Bildung von Figur 2 verwendet wird. Figur 4 wird mit einer Form gemäß Figur B-B gebildet und Figur 5 mit einer Form gemäß Figur B'-B'.In the different sectional representations according to FIG. 10, different designs of both the connection and the arrangement of the first upper sleeve area le and the second upper sleeve area ld are shown. In practice, of course, only the same designs are provided on an upper sleeve. Figure AA shows the shape used to form Figure 3; Figure A'-A 'shows the shape used to form Figure 2. Figure 4 will formed with a shape according to Figure BB and Figure 5 with a shape according to Figure B'-B '.
Figur C-C zeigt eine einfache Lagerung des als Ring ausge- bildeten, unverdrehbaren Obermuffenbereichs le gegenüber dem zweiten Obermuffenbereich ld mittels einer senkrechten Schraube. Bei Figur D-D ist der unverschwenk bare Obermuffenbereich le' über einen Seitenflansch am verschwenkbaren zweiten Obermuffenbereich ld' gelagert. Figur E-E zeigt ei- ne einfache Führung des ersten Obermuffenbereichs le in einer umlaufenden Längsnut des zweiten Obermuffenbereichs ld. Figur F-F zeigt die Übertragung der Andruckkraft vom zweiten verschwenkbaren Obermuffenbereich ld auf den ersten Obermuffenbereich le mit Hilfe eines Kugellagers lg und ei- nes Lagerbolzens lh. FIG. C-C shows a simple mounting of the non-rotatable upper sleeve area le, which is designed as a ring, in relation to the second upper sleeve area ld by means of a vertical screw. In FIG. D-D, the non-pivotable upper sleeve area le 'is mounted on the pivotable second upper sleeve area ld' via a side flange. Figure E-E shows a simple guidance of the first upper sleeve area le in a circumferential longitudinal groove of the second upper sleeve area ld. FIG.
