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.

Description

TECHNISCHE GEBIETTECHNICAL AREA

Die Erfindung betrifft ein Verfahren nach dem Oberbegriff des Patentanspruchs 1 und eine Obermuffe zur Verwendung bei dem erfindungsgemäßen Verfahren.The invention relates to a method according to the preamble of patent claim 1 and an upper sleeve for use in the inventive method.

STAND DER TECHNIKSTATE OF THE ART

Es ist ein Schachtring bekannt (EP 0 759 488 A1), 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 Hohlraum zur Aufnahme einer Dichtung gebildet. Um statisch einwandfreie Verhältnisse zu erhalten, werden an den Auflagerstellen Dreipunktauflagen gebildet. Diese Dreipunktauflagen sind beim gesamten Schacht über die gesamte Bauhöhe innerhalb gemeinsamer vertikaler Ebenen angeordnet.There is a manhole ring known (EP 0 759 488 A1), which consists of concrete or reinforced concrete and has a rotationally symmetrical upper edge and a lower edge. The upper edge is called Schachentringen as a spigot, the lower edge as Muffenende. The upper and lower edges of the known manhole member are shaped so that in the mounted state of two adjacent manhole components circumferentially spaced bearing surfaces are formed. For this purpose, at the lower edge, ie at the socket end, raised bearing surfaces are formed and suitable for bearing on a substantially 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 substantially complementary to this throat formed radial cross-section. In the superimposed state of two manhole components, a cavity is formed between the two edges formed to receive a seal. In order to obtain statically perfect conditions, three-point supports are formed at the bearing points. These three-point supports are arranged throughout the shaft over the entire height within common vertical planes.

Die Fertigung eines solchen Schachtbauteils erfolgt in der bisher üblichen bekannten Art und Weise: Das Muffenende wird auf einer ortsfesten Untermuffe gebildet, das Spitzende von einer Obermuffe, die Teil eines Schachtringfertigers ist und bei der Formung des Spitzendes gleichzeitig um die Längsachse des Schachtrings alternierend hin und her verschwenkt wird und bei dieser alternierenden Verschwenkbewegung abgesenkt wird. Die Bildung der erhabenen Auflagerflächen kann bisher nur am Muffenende mit einer feststehenden Untermuffe erfolgen. Die Anordnung von Auflagerflächen an der Unterseite, also am Muffenende, erweist sich jedoch als nachteilig, weil die nach unten vorspringenden Auflagerflächen beim Transport der Schachtringe an dieser Stelle besonders anfällig gegen Belastungen sind und leicht zerstört werden können. Außerdem ist die Herstellung von Schachtringen mit Auflagerflächen am Muffenende kostspielig, weil hierzu eine große Anzahl von speziell ausgebildeten Untermuffen, die die Formbereiche für die Auflagerflächen aufweisen müssen und nicht einfach rotationssymmetrisch sind, vorgehalten werden muß.The production of such a manhole component takes place in the usual manner known so far: The socket end is formed on a stationary lower sleeve, the spigot of an upper sleeve, which is part of a Schachtringfertigers and at the same time to form the spigot about the longitudinal axis of the chess ring out and is pivoted forth and lowered in this alternating pivoting movement. The formation of the raised support surfaces can be done so far only at the socket end with a fixed lower sleeve. However, the arrangement of bearing surfaces on the underside, so the sleeve end, proves to be disadvantageous because the downwardly projecting bearing surfaces during transport of the manhole rings at this point are particularly vulnerable to stress and can be easily destroyed. In addition, the production of manhole rings with bearing surfaces at the socket end is expensive, because this is a large number of specially trained lower sleeves, which must have the shape of the bearing surfaces and are not simply rotationally symmetric, must be kept.

DIE ERFINDUNGTHE INVENTION

Ausgehend von diesem Stand der Technik liegt der Erfindung die Aufgabe zugrunde, ein Verfahren der als bekannt vorausgesetzten Art so auszubilden, daß es die Bildung von Distanzbereichen am oberen Rand, also am Spitzende erlaubt.Based on this prior art, the present invention seeks to provide a method of known as presupposed type so that it allows the formation of distance ranges at the top, so at the tip end.

Die Lösung dieser Aufgabe erfolgt mit den Merkmalen des Patentanspruchs 1.The solution of this object is achieved by the features of patent 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, während 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 Höhe angeordnet sein als der verbleibende übrige umlaufende Rand, und zwar sowohl nach oben vorspringend als auch gegenüber 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 Auflagerflächen, die am unteren Rand des darüber angeordneten Schachtrings anliegen.The fact that the upper sleeve is no longer integrally formed, but is divided into two different areas, the first is formed without pivoting relative to the upper edge, while the second area remains pivotable, there is the possibility to make a training with a spigot, not is rotationally symmetric. Rather, the distance ranges can be arranged at a different height than the remaining remaining peripheral edge, both projecting upwards and fed in with respect to the rest of the edge. In a respect to the rest of the edge recessed level spacers are inserted into the distance ranges and then form with their tops the bearing surfaces, which bear against the lower edge of the overlying chess ring.

BESTER WEG ZUR AUSFÜHRUNG DER ERFINDUNGBEST MODE FOR CARRYING OUT THE INVENTION

In den Zeichnungen sind gleiche Teile mit den gleichen Bezugszeichen versehen, die sich im Bedarfsfall durch Hochstriche voneinander unterscheiden.In the drawings, like parts are given the same reference numerals, which are different from each other when needed by high marks.

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.In Figure 1, a chess ring paver 1 is shown with its essential parts for a better understanding of the method. On a lower sleeve 3 is a freshly shaped manhole ring 4 with a vertical longitudinal axis 4a. The lower sleeve 3 is rotationally symmetrical. The lower sleeve 3 has formed the socket end of the chess ring 4.

Von dem Schachtring 4 ist ein Spitzendformer abgehoben, der an einer Preßglocke 1c befestigt ist. Der Spitzendformer wird als Obermuffe bezeichnet. Oberhalb der Preßglocke 1c wird der Formmantel 1b zum Absenken für den folgenden Fertigungszyklus bereitgehalten.From the manhole ring 4 a Spitzendformer is lifted, which is attached to a Preßglocke 1c. The Spitzenendformer is referred to as upper sleeve. Above the press bell 1c, the mold shell 1b is kept ready for lowering for the following production cycle.

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 umlaufenden Rand 4e vor.At the designated as a spigot upper edge 4c are distributed uniformly on the circumference usually three distance regions 4d provided. The support surfaces of the distance range 4d protrude with respect to the remaining, 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 ranges 4d can be formed differently. Usually, they are 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 distance regions 4d ', inserts must be inserted which protrude upward beyond 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 completely from concrete, as shown in Figure 2 at 4d. But it is also possible to produce the bearing areas at least partially made of other materials and mold or mold. In the embodiment according to FIGS. 6 and 7, the core of the support region 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 essential feature of the upper sleeve is that it is designed to be split. The structure can be seen in FIG. 8:

Ein erster Obermuffenbereich 1e wird über eine nicht genauer 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 1e, 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 1f vorgesehen, welche von den Haltern 10 durchsetzt werden. Auf diese Weise ergibt sich die relative Schwenkbeweglichkeit zwischen dem ersten Obermuffenbereich 1e und dem zweiten Obermuffenbereich 1d.A first upper sleeve portion 1e is non-rotatably on a vertical via a mechanism not shown in detail Support 7 held. Within the support 7 there is a central shaft 8, which is alternately pivotable 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 spigot end. The first upper sleeve portion 1e, which is non-pivotable, is connected to the molding-fixed portion 11 via holders 10. Thus, the first and second upper sleeve area are pivotally movable relative to each other, arcuate slots 1f are provided on the first upper sleeve area, which are penetrated by the holders 10. In this way, the relative pivoting mobility between the first upper sleeve portion 1e and the second upper sleeve portion 1d results.

In Figur 7 ist dargestellt, daß der unverdrehbare Obermuffenbereich 1e 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.FIG. 7 shows that the non-rotatable upper sleeve region 1e has a receptacle for a cap 6 which can be pressurized with negative pressure. In this way, the cap 6 is held in forming the spigot end 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 1e und zweiten Obermuffenbereich 1d 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'.Different embodiments of both the connection and the arrangement of the first upper sleeve region 1e and the second upper sleeve region 1d are shown in the various sectional views according to FIG. Of course, in practice only the same versions are provided on an upper sleeve. Figure AA shows the mold used to form Figure 3, Figure A'-A 'shows the mold used to form Figure 2. Figure 4 is 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 ausgebildeten, unverdrehbaren Obermuffenbereichs 1e gegenüber dem zweiten Obermuffenbereich 1d mittels einer senkrechten Schraube. Bei Figur D-D ist der unverschwenk bare Obermuffenbereich 1e' über einen Seitenflansch am verschwenkbaren zweiten Obermuffenbereich 1d' gelagert. Figur E-E zeigt eine einfache Führung des ersten Obermuffenbereichs 1e in einer umlaufenden Längsnut des zweiten Obermuffenbereichs 1d. Figur F-F zeigt die Übertragung der Andruckkraft vom zweiten verschwenkbaren Obermuffenbereich 1d auf den ersten Obermuffenbereich 1e mit Hilfe eines Kugellagers 1g und eines Lagerbolzens 1h.Figure C-C shows a simple storage of trained as a ring, non-rotatable upper sleeve portion 1e relative to the second upper sleeve portion 1d by means of a vertical screw. In Figure D-D is the unverschwenk bare upper sleeve portion 1e 'via a side flange on the pivotable second upper sleeve portion 1d' stored. Figure E-E shows a simple guidance of the first upper sleeve portion 1e in a circumferential longitudinal groove of the second upper sleeve portion 1d. Figure F-F shows the transmission of the pressing force from the second pivotable upper sleeve portion 1d on the first upper sleeve portion 1e by means of a ball bearing 1g and a bearing pin 1h.

    the spacer zones (4d) are provided on the upper edge (4c) formed by the upper sleeve (1d; 1e) and the upper sleeve (1d; 1e) is divided into two different regions (le and 1d) of which the first region (1e) is designed so that it cannot turn relative to the upper edge (4c) but forms the spacer zones (4d) wherein the second region (1d) is mounted able to drop down jointly with the first region (1e) and able to turn relative to same in alternation wherein the shaping of the upper edge (4c) is carried out by means of the divided upper sleeve (1d; 1e) in such a way that the spacer zones (4d) are formed through the non-rotatable first region (1e) of the upper sleeve and the remaining upper edge (4e) is formed by the second region (1d) of the upper sleeve which can rotate in opposite directions.
  2. Upper sleeve for producing a manhole ring (4) according to the method according to claim 1,
    characterised in that
    a second upper sleeve region (1d) which is able to rotate in opposite directions about the axis of symmetry of the manhole ring has the profile to shape the upper edge (4c) and that a first non-rotatable upper sleeve region (1e) has a holder (10) which passes through the second upper sleeve region (1d) and supports the shaping area for the spacer zone (4d).
  3. Upper sleeve according to claim 2,
    characterised in that
    the holder (10) for the shaping area of the spacer zone (4d) passes through a circular arc-shaped oblong hole of the second upper sleeve region (1d).
  4. Upper sleeve according to claim 2 or 3,
    characterised in that
    the second upper sleeve region (1d) is designed for entrainment of the first upper sleeve region (1e) during the formation of the upper edge (4c).
