Description

Die Erfindung bezieht sich auf eine Vorrichtung zum Formen von jeweils wenigstens zwei Anschlußmuffen aufweisenden Kanalisationsschächten, insbesondere von Unterteilen von Kanalisationsschächten, mit einem Muffeneinsätze aufweisenden Formmantel und einem in diesem angeordneten Formkern, an dessen einer Stirnseite eine an die Form eines Gerinnes im Boden des jeweiligen Kanalisatonsschachts angepaßte Schablone mit einem nach außen ragenden Vorsprung angeordnet ist, der eine an die Wand des Gerinnes im Boden des Schachts angepaßte Außenfläche aufweist.The invention relates to a device for forming sewer shafts each having at least two connecting sleeves, in particular the lower parts of sewer shafts, with a molded jacket having sleeve inserts and a mold core arranged in the latter, on one end face of which one conforms to the shape of a channel in the bottom of the respective sewer shaft adapted template is arranged with an outwardly projecting projection which has an outer surface adapted to the wall of the channel in the bottom of the shaft.

Es ist eine Vorrichtung zum Formen von Kanalisationsschächten bekannt, die wenigstens zwei Anschlußmuffen aufweisen. Diese bekannte Vorrichtung enthält wenigstens zwei, vorzugsweise gegeneinander verdrehbare Formmantelabschnitte und einen wenigstens ein Mantelsegment aufweisenden Formmantel, in dem ein Formkern angeordnet ist. Die Formmantelabschnitte sind mit Muffeneinsätzen versehen. Der Formkern ist ein Zylinder. Die Formmantelabschnitte und die Mantelsegmente sind durch koaxial zum Formmantel verlaufende Spannringe lagefixiert. Mit der bekannten Vorrichtung können die Anschlußmuffen an verschiedenen Stellen des Umfangs angebracht werden, so daß ein gewünschter Winkelverlauf entsteht. Da der Formkern zylindrisch ist, weisen die Kanalisationsschächte ebene, kreisförmige Böden auf (EP 0 489 302 A1).A device for forming sewer shafts is known which has at least two connecting sleeves. This known device contains at least two, preferably mutually rotatable molded jacket sections and a molded jacket having at least one jacket segment, in which a mold core is arranged. The shaped jacket sections are provided with socket inserts. The mandrel is a cylinder. The shaped jacket sections and the jacket segments are fixed in position by means of tension rings running coaxially to the shaped jacket. With the known device, the connecting sleeves can be attached at various points on the circumference, so that a desired angular profile is produced. Since the mandrel is cylindrical, the Sewerage shafts on flat, circular floors (EP 0 489 302 A1).

Um das Abwasser und die von ihm mitgeführten Abfälle durch die Kanalisationsschächte gezielt hindurchzuleiten, sind die Böden dieser Schächte vielfach mit Gerinnen versehen, die zwischen den seitlichen Wanddurchlässen verlaufen. Zu den Rändern der Gerinne hin, weisen die Böden der Schächte Gefälle auf, so daß Abwässer, die durch höher liegende Einlaßöffnungen in die Schächte gelangen, in das Gerinne am Boden des jeweiligen Schachts fließen und von dort zu der Auslaßöffnung des Schachts gelangen.In order to direct the waste water and the waste it carries through the sewage shafts, the bottoms of these shafts are often provided with channels that run between the side wall openings. The bottoms of the shafts have a slope towards the edges of the channels, so that waste water which enters the shafts through higher inlet openings flows into the channel at the bottom of the respective shaft and from there to the outlet opening of the shaft.

Nach dem Aufstellen des jeweiligen Schachts werden das Gerinne und die geneigten Bodenflächen durch Ausmauern hergestellt.After the installation of the respective shaft, the channel and the inclined floor surfaces are made by bricking.

Vorrichtungen der eingangs genannten Art sind dem DE 84 23 080 U1 bzw. der DE 41 20 483 C2 zu entnehmen. Die Schablonen umfassen Tunnelteile für Grundformen von auszubildenden Gerinnen. Ferner muß der Formkern einen Formboden aufweisen, um die Tunnelteile gegebenenfalls drehbar anzuordnen und zu positionieren. Um Gerinne mit gewünschtem Gefälle zu erhalten, muß auf die zuvor beschriebenen Techniken zurückgegriffen werden.Devices of the type mentioned at the outset can be found in DE 84 23 080 U1 and DE 41 20 483 C2. The templates include tunnel parts for basic forms of channels to be trained. Furthermore, the mold core must have a mold base in order to possibly arrange and position the tunnel parts rotatably. In order to obtain channels with the desired slope, the techniques described above must be used.

Der Erfindung liegt das Problem zugrunde, eine Vorrichtung zum Formen von zumindest zwei Anschlußmuffen aufweisenden Kanalisationsschächten oder Schachtunterteilen zu entwickeln, bei der Gerinne in ihren Gefällflächen bereits bei der Schachtherstellung ausgebildet werden können. Gleichzeitig soll sich eine konstruktiv einfach aufgebaute Vorrichtung ergeben, in der zum einen auf einfache Art das Gerinne hergestellt und zum anderen nach dessen Ausbilden der Formkern mit der Schablone problemlos entfernt und einer erneuten Verwendung zugeführt werden kann.The invention is based on the problem of developing a device for forming sewer shafts or manhole bases having at least two connecting sleeves, in which channels can be formed in their inclined surfaces during manhole manufacture. At the same time, a structurally simple device is to be produced, in which the channel can be produced in a simple manner and, after it has been formed, the mold core can be easily removed with the template and reused.

Das Problem wird bei einer Vorrichtung der eingangs beschriebenen Art erfindungsgemäß dadurch gelöst, daß der Vorsprung (50) einen ersten Abschnitt (100), der an seiner Basis in die Flächen für das Gefälle des Bodens des Schachts übergeht, und einen zweiten gewölbten Abschnitt (102) aufweist, der sattelförmig an das Gefälle des Gerinnebodens angepaßt und mit dem ersten Abschnitt (100) lösbar verbunden ist. Beim Gießen des jeweiligen Kanalisationsschachtes bzw. Schachtunterteils sorgt die Schablone dafür, daß am Boden des Schachts das Gerinne und die Gefällflächen ausgebildet werden. Schacht und Gerinne bilden ein Monolith. Es ist nicht mehr notwendig, nach dem Aufstellen des jeweiligen Schachts durch Ausmauern am Schachtboden ein Gerinne mit Gefällflächen anzufertigen. Damit erübrigen sich Arbeiten an den Schächten vor Ort, die nur mit einem gewissen Aufwand ausgeführt werden können. Dieser Aufwand besteht z.B. darin, daß geeignete Mauersteine zum Aufstellungsort transportiert werden müssen und Mörtel hergestellt werden muß. Für das Ausmauern ist handwerkliches Können notwendig, über das nur Fachpersonal verfügt. Durch die Erfindung läßt sich dieser Aufwand vermeiden, so daß die Erstellung der Kanalisation wirtschaflicher wird.The problem is solved according to the invention in a device of the type described in the introduction in that the projection (50) has a first section (100) which at its base merges into the areas for the slope of the bottom of the shaft and one has a second curved section (102) which is saddle-shaped to the slope of the channel bottom and is detachably connected to the first section (100). When pouring the respective sewage shaft or lower part of the shaft, the template ensures that the channel and the inclined surfaces are formed on the bottom of the shaft. The shaft and channel form a monolith. It is no longer necessary to create a channel with inclined surfaces by lining up the shaft base after the respective shaft has been erected. This eliminates the need to work on the shafts on site, which can only be carried out with a certain amount of effort. This effort consists, for example, in the fact that suitable bricks have to be transported to the installation site and mortar has to be produced. For the masonry, craftsmanship is required, which only specialist personnel have. This effort can be avoided by the invention, so that the construction of the sewage system becomes more economical.

Vorzugsweise hat die Schablone einen kreisrunden Rand und einen gegen diesen radial nach innen versetzten Absatz, der mit geringem Spiel in den hohlzylindrischen Formkern einsetzbar ist. Diese Ausführungsform stellt die Zentrierung und Fixierung der Schablone im Formkern sicher.The template preferably has a circular edge and a shoulder offset radially inward relative to this, which can be inserted into the hollow cylindrical mandrel with little play. This embodiment ensures that the template is centered and fixed in the mandrel.

Erfindungsgemäß ragt von der dem Absatz abgewandten Seite der Schablone wenigstens ein Vorsprung nach außen, der in seinem Querschnitt und Verlauf an das Gerinne im Boden des Schachts anpaßbar ist. Die Schablone hat also mindestens eine Wölbung oder Ausbauchung, die auf ihren Außenseiten die Flächen des Gerinnes und die Neigungsflächen des Schachtbodens festlegt.According to the invention, at least one protrusion protrudes outwards from the side of the template facing away from the heel and its cross-section and shape can be adapted to the channel in the bottom of the shaft. The template therefore has at least one curvature or bulge, which defines the surfaces of the channel and the inclined surfaces of the shaft floor on its outer sides.

Der Vorsprung umfaßt einen ersten Abschnitt, der an seiner Basis in die Flächen für die Bildung des Gefälles am Boden des Schachts übergeht und einen austauschbaren zweiten, gewölbten Abschnitt, der sattelförmig an das Gefälle des Gerinnebodens angepaßt und mit dem ersten Abschnitt lösbar verbunden ist. Hierdurch wird das Problem gelöst, auf wirtschaftliche Weise an Schächten oder Schachtunterteilen Gerinne mit gewünschten Neigungen herstellen zu können. Die zweiten Abschnitte der Vorsprünge sind auswechselbar und jeweils an ein bestimmtes Gefälle angepaßt. Daher ist es nicht notwendig, für die verschiedenen, vorgegebenen Gefälle jeweils eine Schablone vorrätig zu halten. Es reicht ein Satz an zweiten Abschnitten aus, die wesentlich einfacher ausgebildet sind als die kompletten Schablonen und deshalb kostengünstig hergestellt werden können.The projection comprises a first section, which at its base merges into the areas for the formation of the slope at the bottom of the shaft and an exchangeable second, arched section which is adapted in a saddle shape to the slope of the channel bottom and is detachably connected to the first section. This solves the problem of being able to produce channels with desired inclinations economically on manholes or manhole bases. The second sections of the protrusions are interchangeable and each adapted to a certain slope. It is therefore not necessary to keep a template in stock for the different, specified gradients. A set of second sections is sufficient, which are much simpler than the complete templates and can therefore be produced inexpensively.

Durch die erfindungsgemäße Lehre ist die Möglichkeit gegeben, eine Schablone mit austauschbaren, unterschiedliche Dimensionierungen aufweisenden zweiten Abschnitten zu versehen, um Schächte mit Gerinnen unterschiedlicher Gefälle herzustellen, ohne daß Änderungen an dem ersten als Basiskörper zu bezeichnenden Abschnitt der Schablone selbst erfolgen müssen.The teaching according to the invention makes it possible to provide a template with interchangeable second sections of different dimensions in order to produce manholes with channels of different slopes without changes to the first section of the template itself, which is to be referred to as the base body.

Es ist günstig, wenn der zweite Abschnitt eine an den Boden des Gerinnes angepaßte Wölbung hat, deren eines Ende mit einer sichelförmigen Wand verbunden ist, die eine Leiste trägt, die an, ersten Abschnitt anschraubbar ist. Die Abstände zwischen dem äußeren und inneren Rand in der Mitte der Wand legen hierbei das Gefälle des Gerinnes fest.It is favorable if the second section has a curvature which is adapted to the bottom of the channel, one end of which is connected to a crescent-shaped wall which carries a strip which can be screwed onto the first section. The distances between the outer and inner edge in the middle of the wall determine the slope of the channel.

Zweckmäßigerweise verläuft der Vorsprung gerade von einer Stelle des Rands der Schablone zu einer anderen Stelle am Rand und hat an seinen Stirnseiten Wände. Diese Wände befinden sich an Stellen, die bei der Herstellung der Schachtunterteile mit den Durchlaßöffnungen der Muffen fluchten.The projection expediently runs straight from one point on the edge of the template to another point on the edge and has walls on its end faces. These walls are located at locations that are aligned with the through openings of the sleeves during the manufacture of the manhole bases.

Die vorstehend beschriebene Schablone ist für Schachtböden bestimmt, die gerade Gerinne aufweisen, die sich quer längs eines Durchmessers über den Schachtboden erstrecken.The template described above is intended for manhole floors which have straight channels which extend across the shaft bottom transversely along a diameter.

Bei einer weiteren günstigen Ausführungsform verläuft der Vorsprung von einer Stelle des Rands der Schablone in einem runden Bogen zu einer anderen Stelle des Rands und hat an den Stirnseiten Wände. Vorzugsweise umfaßt der Boden einen Viertelkreis. Mit der vorstehend beschriebenen Schablone lassen sich Kanalisationsschächte bzw. Schachtunterteile herstellen, deren Gerinne am Schachtboden jeweils die Abwasserströme z.B. um 90° im Bogen umlenken. Solche Schächte befinden sich z.B. in Straßenkurven.In a further advantageous embodiment, the projection extends from one point on the edge of the template in a round arc to another point on the edge and has walls on the end faces. The base preferably comprises a quarter circle. With The template described above can be used to produce sewage shafts or manhole bases, the channels of which on the bottom of the shaft deflect the wastewater flows, for example by 90 ° in an arc. Such shafts are located, for example, in road curves.

Eine andere zweckmäßige Ausführungsform besteht darin, daß drei Vorsprünge, die je von einer Stelle am Rand der Schablone ausgehen, sich in der Mitte der Schablone vereinigen und an ihren Stirnseiten am Rand der Schablone jeweils Wände aufweisen. Mit dieser Schablone können sich gabelnde Rinnen in den Schachtböden hergestellt werden.Another advantageous embodiment is that three projections, each starting from a location on the edge of the template, unite in the middle of the template and each have walls on their end faces on the edge of the template. With this template, forked channels can be made in the shaft floors.

Die Abstände zwischen den Öffnungen der Vorsprünge sind vorzugsweise verschieden. Mit dieser Schablone können Kanalisationsschächte hergestellt werden, die am Boden an zwei oder drei Kanäle angeschlossen werden. Aufgrund der unterschiedlichen Abstände zwischen den Öffnungen ergeben sich unterschiedliche Umlenkwinkel für die Abwasserströme.The distances between the openings of the projections are preferably different. This template can be used to produce sewage ducts that are connected to two or three ducts on the floor. Due to the different distances between the openings, there are different deflection angles for the waste water flows.

Vorzugsweise sind die Deckel mit einem gegen den Deckelrand nach innen versetzten, axial auf der den Wölbungen entgegengesetzten Seiten vorspringenden Absatz versehen. Mit Hilfe des Absatzes werden die Deckel auf den Zylinderkernen fixiert. Der Aufbau der Form für die Herstellung der Kananlisationsschächte und der Ausbau der Teile im Inneren des Kanalisationsschachtes wird hierdurch erleichtert.The lids are preferably provided with a shoulder offset inwards against the lid edge and projecting axially on the side opposite the curvatures. With the help of the heel, the covers are fixed on the cylinder cores. This makes it easier to set up the mold for the manufacture of the sewerage shafts and to remove the parts inside the sewerage shaft.

Weitere Einzelheiten, Vorteile und Merkmale der Erfindung ergeben sich nicht nur aus den Ansprüchen und den diesen zu entnehmenden Merkmalen -für sich und/oder in Kombination-, sondern auch aus der nachfolgenden Beschreibung eines bevorzugten Ausführungsbeispiels.Further details, advantages and features of the invention result not only from the claims and the features to be extracted from them - individually and / or in combination - but also from the following description of a preferred exemplary embodiment.

Zur Herstellung von Kanalisationsschächten, insbesondere der Unterteile von aus einem Unterteil und weiteren Ringen bestehenden Kanalisationsschächten, wird eine Vorrichtung verwendet, die mit Abwandlungen der in der EP 0 489 302 A1 beschriebenen Vorrichtung entsprechen kann. Eine Vorrichtung (10) zur Herstellung von Kanalisationsschächten, insbesondere von Unterteilen von Kanalisationsschächten, weist einen hohlzylindrischen Formmantel (12) auf, in dem koaxial ein hohlzylindrischer Formkern (14) angeordnet ist.A device is used to manufacture sewer shafts, in particular the lower parts of sewer shafts consisting of a lower part and further rings used, which can correspond with modifications of the device described in EP 0 489 302 A1. A device (10) for producing sewer shafts, in particular the lower parts of sewer shafts, has a hollow cylindrical shaped jacket (12) in which a hollow cylindrical shaped core (14) is arranged coaxially.

Der Formmantel (12) besteht aus Seitenmuffen (16) aufweisenden Formmantelabschnitten oder Muffenspiegeln (18) sowie Formmantelsegmenten (20) und (22), die in einem Umfang überlappend angeordnet sind, daß sich ein Formmantel (12) in geschlossener Form ergibt.The shaped jacket (12) consists of side sleeves (16) having shaped jacket sections or sleeve mirrors (18) as well as shaped jacket segments (20) and (22) which are arranged so as to overlap to the extent that a shaped jacket (12) results in a closed shape.

Damit die Formmantelabschnitte (18) sowie die Formmantelsegmente (20) und (22) zur Bildung des Formmantels (12) lagefixiert werden können, sind Spannringe (24) und (26) vorgesehen, die in von den Formmantelabschnitten (18) und den Formmantelsegmenten (20), und (22) abragende Aufnahmen wie mit Schlitzen versehene Konsolen (28) und (30) einbringbar sind.So that the shaped jacket sections (18) and the shaped jacket segments (20) and (22) for forming the shaped jacket (12) can be fixed in position, clamping rings (24) and (26) are provided, which are formed by the shaped jacket sections (18) and the shaped jacket segments ( 20), and (22) protruding receptacles such as slotted brackets (28) and (30) can be introduced.

Von den Seitenmuffen (16) gehen Aussparkerne (32) aus, die eine Verbindung zu einer Schablone (34) bzw. Gießform herstellen, die auf der oberen Stirnseite des hohlzylindrischen Formkerns (14) aufliegt und diesen deckelförmig verschließt.From the side sleeves (16) there are recess cores (32) which create a connection to a template (34) or casting mold which rests on the upper end face of the hollow cylindrical mandrel (14) and closes it in a lid-like manner.

Da die den Formmantel (12) bildenden Elemente (18), (20) und (22) von den Spannringen (24) und (26) lagepositioniert sind, bedarf es keiner zusätzlichen Halteelmente bzw. Zahnkränze und mit diesen wechselwirkenden Ritzel, um die Elemente derart zueinander zu verscheiben, daß die Muffeneinsätze gewünschte Winkel zueinander beschreiben.Since the elements (18), (20) and (22) forming the shaped jacket (12) are positioned in position by the tension rings (24) and (26), no additional holding elements or toothed rings and pinions interacting with them are required to the elements to be glazed to one another in such a way that the socket inserts describe the desired angles to one another.

Wie insbesondere die Draufsicht der Vorrichtung (10) verdeutlicht, kann z.B. der dargestellte Winkel von 180° zwischen den gegenüberliegen Seitenmuffen (16) dadurch verändert werden, daß die als Muffenspiegel zu bezeichnenden Formmantelabschnitte (18) gegeneinander verdreht werden, wobei die Spannringe (24) und (26) Führungen bilden. In Abhängigkeit von dem Verdrehen der Muffenspiegel (18) gegeneinander überlappen sich die Formmantelsegmente (20) mit den von den Muffenspiegeln (18) ausgehenden segmentenförmigen Abschnitten (36) und (38) bzw. den als Winkelformbleche zu bezeichnenden Formmantelsegmenten (20) mehr der weniger.As is particularly clear from the top view of the device (10), the angle shown, for example, of 180 ° between the opposite side sleeves (16) can be changed in that the shaped jacket sections to be referred to as sleeve mirrors (18) are rotated against each other, the clamping rings (24) and (26) forming guides. Depending on the twisting of the socket mirrors (18) relative to one another, the shaped jacket segments (20) overlap with the segmented sections (36) and (38) starting from the socket mirrors (18) or with the shaped jacket segments (20) to be designated as angular shaped sheets .

Die Fig. 1 verdeutlicht, daß die mittleren Formmantelsegmente (22) in bezug auf die von den Muffenspiegeln (18) ausgehenden Mantelsegmentabschnitte (36) und (38) bzw. den Wechselformblechen innenliegend verlaufen. Dannoch bedarf es für die Formmantelsegemente (22) nur in deren Mittenbereich jeweils einer unteren bzw. oberen Spannringkonsole (28) und (30), die in der Fig. 1 allgemein mit den Bezugszeichen (40) und (42) versehen sind, ohne daß die Gefahr besteht, daß die Segmente (22) beim Ausfüllen der Form wegkippen; denn die Segmente (22) werden außenseitig von den Segmentabschnitten (36) und (38) bzw. von den Mantelsegmenten (20) abgestützt.Fig. 1 illustrates that the central molded jacket segments (22) with respect to the jacket segment sections (36) and (38) or the interchangeable shaped sheets extending from the socket mirror (18) run inside. Then, only one lower or upper clamping ring bracket (28) and (30) is required for the shaped jacket segments (22) in their central area, which are generally provided with the reference numerals (40) and (42) in FIG. 1, without there is a risk that the segments (22) will tip away when filling the mold; because the segments (22) are supported on the outside by the segment sections (36) and (38) or by the shell segments (20).

Die Gießform bzw. Schablone (34) ist so ausgebildet, daß am Boden des Schachtunterteils ein Gerinne entsteht. Die Form bzw. Schablone (34) besteht z.B. aus Metall und hat einen kreisrunden Rand (44). Auf einer Seite der Schablone (34) ist radial nach innen gegen den Rand (44) versetzt ein Absatz (46) vorgesehen, der an den Innendurchmesser des Formkerns (14) so angepaßt ist, daß der Absatz (46) mit geringem Spiel in den Hohlraum ragt, während sich die Schablone (34) mit der ringförmigen Fläche zwischen Rand (44) und Absatz (46) auf der einen Stirnfläche des hohlzylindrischen Formkerns (14) abstützt. Der kreisförmige Rand (44) und der Absatz (46) ist bei allen Ausführungsformen von Schablonen bzw. Gießformen in gleicher Weise vorgesehen. Deshalb sind diese Elemente bei den in den Fig. 3 bis 8 dargestellten Ausführungsformen von Schablonen mit den gleichen Bezugsziffern versehen.The casting mold or template (34) is designed such that a channel is formed on the bottom of the lower part of the shaft. The shape or template (34) consists e.g. made of metal and has a circular rim (44). On one side of the template (34) is offset radially inward against the edge (44), a shoulder (46) is provided which is adapted to the inner diameter of the mandrel (14) so that the shoulder (46) with little play in the Cavity protrudes, while the template (34) with the annular surface between the edge (44) and shoulder (46) is supported on one end face of the hollow cylindrical mandrel (14). The circular edge (44) and the shoulder (46) are provided in the same manner in all embodiments of templates or casting molds. Therefore, these elements are provided with the same reference numerals in the embodiments of stencils shown in FIGS. 3 to 8.

Die Schablone (34) ist deckelförmig ausgebildet und besitzt einen längs einer Durchmesserlinie (48) geradlinig verlaufenden Vorsprung (50), der auf der dem Absatz (46) entgegengesetzten Seite nach außen ragt. Der Vorsprung (50) erstreckt sich bis an den Rand (44) und ist an die Gerinneform angepaßt, d. h. er weist einen halbzylinderförmigen Teil (52) auf, dessen Längsränder in im wesentlichen ebene Flächenabschnitte (54) übergehen, die jeweils in abgewinkelte, muldenförmige Flächenabschnitte (56) übergehen, die zum Rand (44) hin geneigt sind. Die Flächenabschnitte (56) - auch als Gefällflächen bezeichnet -, sind kreissegmentförmig und ihre Neigung beträgt insbesondere 1:20, wobei der Rand (44) bei auf dem Formzylinder (14) aufliegender Schablone (34) tiefer als die unteren Enden der Flächenabschnitte (54) liegt. An beiden Stirnseiten des Vorsprungs (50) sind Wände (58) vorgesehen, die den Aussparkernen (32) gegenüberstehen, wenn die Schablone (34) auf dem Formkern (14) aufliegt.The template (34) is designed in the form of a lid and has a projection (50) which runs in a straight line along a diameter line (48) and projects outwards on the side opposite the shoulder (46). The projection (50) extends to the Edge (44) and is adapted to the channel shape, ie it has a semi-cylindrical part (52), the longitudinal edges of which merge into essentially flat surface sections (54), each of which merges into angled, trough-shaped surface sections (56) which lead to the edge ( 44) are inclined. The surface sections (56) - also referred to as sloping surfaces - are in the form of a segment of a circle and their inclination is 1:20 in particular, the edge (44) with the template (34) resting on the forme cylinder (14) lower than the lower ends of the surface sections (54 ) lies. Walls (58) are provided on both ends of the projection (50), which face the recess cores (32) when the template (34) rests on the mold core (14).

Beim Einfüllen von Beton in die Vorrichtung (10) formt die Schablone (34) ein über den Boden des Schachtunterteils verlaufendes Gerinne und geneigte ebene Gefälleflächen zwischen den Rändern des Bodens und den Rändern der Rinne. Nach dem Aushärten des Betons werden der Formzylinderkern (14) und die Schablone (34) aus dem Inneren des Schachtunterteils herausgenommen. Ein monolithischer Schacht mit Gerinne gewünschtem Gefälles steht zur Verfügung.When pouring concrete into the device (10), the template (34) forms a channel running over the bottom of the manhole base and inclined flat inclined surfaces between the edges of the bottom and the edges of the channel. After the concrete has hardened, the forme cylinder core (14) and the template (34) are removed from the interior of the manhole base. A monolithic shaft with a desired slope is available.

Durch anders ausgebildete Schablonen können unterschiedliche Gerinneformen hergestellt werden. In den Fig. 4a und b ist eine Form bzw. Schablone (60) dargestellt, die ebenso wie die Schablone (34) einen kreisförmigen Rand (44) mit gegen diesen radial nach innen versetzten Absatz (46) aufweist. Die Schablone (60) hat ebenfalls die Form eines kreisrunden Deckels und weist einen nach einer Seite ragenden Vorsprung (62) auf, der einen Bogen beschreibt, der einen Viertelkreis umfaßt. Der Vorsprung (62) setzt sich aus einem Abschnitt (64) mit im Querschnitt halbförmigem Bogen und aus einem Abschnitt (66) zusammen, der Wände hat, die jeweils ein Viertel eines Kegelstumpfmantels bilden. Von den Basen der Wände des Abschnitts (66) gehen geneigte, muldenförmige Flächen bzw. Gefällflächen (68, 70) aus, die zum Rand (44) hin verlaufen. Die Neigung dieser Flächen beträgt ebenso wie die der Flächen (56) 1:20.Different channel shapes can be produced using differently designed templates. 4a and b show a shape or template (60) which, like the template (34), has a circular edge (44) with a shoulder (46) offset radially inward relative to it. The template (60) also has the shape of a circular lid and has a protrusion (62) protruding to one side, which describes an arc which comprises a quarter circle. The projection (62) is composed of a section (64) with a semi-circular cross-section and a section (66) which has walls which each form a quarter of a truncated cone. Inclined, trough-shaped surfaces or inclined surfaces (68, 70) extend from the bases of the walls of section (66) and run towards the edge (44). The inclination of these surfaces, like that of surfaces (56), is 1:20.

Durch den Vorsprung (62) wird im Schachtboden eine Rinne erzeugt, durch die das Abwasser um 90° längs eines Bogens umgelenkt wird. Die Schablone (62) hat an ihren Stirnseiten Wände (72), die den entsprechend eingestellten Aussparkernen (32) gegenüberstehen.Through the projection (62) a groove is created in the shaft floor through which Waste water is deflected by 90 ° along an arch. The template (62) has walls (72) on its end faces, which face the correspondingly set recess cores (32).

Eine andere Ausführugsform einer Schablone ist in den Fig. 5a und b dargestellt. Die Schablone (74) gemäß Fig. 5a, b hat ebenfalls die Form eines Deckels mit kreisförmigem Rand (44) und einem Absatz (46) zur Lagefixierung.Another embodiment of a template is shown in FIGS. 5a and b. The template (74) according to Fig. 5a, b also has the shape of a cover with a circular edge (44) and a shoulder (46) for fixing the position.

Die Fig. 5a und b zeigen eine Schablone (74) für ein Schachtunterteil, das eine sich gabelnde Rinne aufweist. Die Schablone (74) bzw. Gießform für den Boden des Schachtunterteils ist ebenso wie die oben beschriebene Gießform als Deckel mit kreisförmigem Rand (44) ausgebildet, gegen den ein Absatz (46) radial nach innen versetzt ist. Der Absatz (46) ragt bei der komplett zusammengesetzten Gießform für das Schachtunterteil in das Innere das hohlzylindrischen Formzylinders (14) und fixiert so die Schablone (74). Von der dem Absatz (46) abgewandten Seite der deckelförmigen Schablone (74) ragt ein konvexer Vorsprung (76) vor, der drei Abschnitte (78), (80), (82) aufweist, die ungefähr in der Mitte der Schablone (74) ineinander übergehen und damit eine sich gabelnde Ausbauchung auf einer Schablonenseite bilden. Die drei Abschnitte (78), (80), (82) erstrecken sich bis an den Deckelrand (44) und weisen jeweils an den Stirnseiten Wände (84) auf, die bei montierter Gießform, d. h. bei auf dem Formzylinder (14) aufgesetzter Schablone (74), Aussparkernen (32) gegenüberstehen, sofern die Vorrichtung (10) mit drei Aussparkernen (32) versehen ist. Die Abschnitte (78), (80), (82) haben Querschnitte wie die oben beschriebenen Vorsprünge (50), (62), wobei die Abschnitte (78), (80), (82) bzw. Ausbauchungen in der Schablonenmitte durch den Übergang ineinander eine Zone mit größerem Querschnitt bilden. Die Mitten (86), (88), (90) der drei Stirnseiten (78), (80), (82) weisen unterschiedliche Abstände zueinander auf. Von den Basen der Vorsprünge (78), (80), (82) gehen muldenförmige Flächen (92), (94), (96) aus, die sich zu dem Rand (44) erstrecken und jeweils eine Neigung gegen den Rand (44) haben, so daß die Flächen (92), (94), (96) nahe an den Abschnitten (78), (80), (82) gegenüber dem Rand (44) ein zu den Mitten der Abschnitte (78), (80), (82) hin verschobenes Niveau haben. Die Neigungen der Flächen sind insbesondere 1:20.5a and b show a template (74) for a manhole base which has a forked channel. The template (74) or casting mold for the bottom of the manhole base, like the casting mold described above, is designed as a cover with a circular edge (44) against which a shoulder (46) is offset radially inwards. In the case of the completely assembled casting mold for the manhole base, the shoulder (46) projects into the interior of the hollow cylindrical form cylinder (14) and thus fixes the template (74). A convex projection (76) protrudes from the side of the lid-shaped template (74) facing away from the shoulder (46) and has three sections (78), (80), (82), which are approximately in the center of the template (74) merge into one another and thus form a bifurcating bulge on one side of the template. The three sections (78), (80), (82) extend to the lid edge (44) and each have on the end faces walls (84) which, when the casting mold is mounted, ie when the template is placed on the forme cylinder (14) (74), recess cores (32) face each other if the device (10) is provided with three recess cores (32). The sections (78), (80), (82) have cross sections like the projections (50), (62) described above, the sections (78), (80), (82) or bulges in the center of the template through the Form a transition into one another with a larger cross-section. The centers (86), (88), (90) of the three end faces (78), (80), (82) are at different distances from one another. Trough-shaped surfaces (92), (94), (96) extend from the bases of the projections (78), (80), (82) and extend to the edge (44) and each incline towards the edge (44 ) so that the surfaces (92), (94), (96) close to the sections (78), (80), (82) opposite the edge (44) towards the centers of the sections (78), (80), (82) have shifted levels. The slopes are especially 1:20.

Die Schablone (74) bzw. Gießform erzeugt im Schachtuntertiel eine sich gabelnde Rinne, die zum Zusammenführen von Abwasserströmen verwendet werden kann, die aus verschiedenen Richtungen im Schacht vereinigt und in einem einzigen Kanal weitergeleitet werden sollen.The template (74) or casting mold creates a forked channel in the manhole base, which can be used to bring together wastewater streams that are to be combined from different directions in the manhole and to be passed on in a single channel.

Die Schablone (74) kann auch bei Schachtunterteilen verwendet werden, die nur zwei Kanaleingänge aufweisen. In Abhängigkeit von den Richtungen, unter denen die Kanäle am Schachtunterteil zusammengeführt werden, können dann zwei der drei Teilrinnen ausgewählt werden, die für das Zusammenführen der Abwasserströme geeigent sind.The template (74) can also be used for manhole bases that only have two channel entrances. Depending on the directions in which the channels are brought together on the lower part of the shaft, two of the three partial channels can then be selected which are suitable for bringing together the waste water flows.

Gerinne an den Böden von Schächten müssen vielfach in ihren Neigungen von einer Schachtöffnung zur anderen an die jeweilige Neigung der an den Schacht angrenzenden Kanalrohre angepaßt werden. In einer erfindungsgemäßen Weiterbildung wird eine Schablone (98) verfügbar gemacht, die in den Fig. 6 bis 8 näher dargestellt ist und aus einem ersten Abschnitt (100) der unabhängig vom Gefälle des Gerinnebodens verwendet werden kann, und aus einem zweiten Abschnitt (102) besteht, der lösbar am ersten Abschnitt (100) befestigt ist und in seiner Neigung an die gewünschte Neigung bzw. das Gefälle des Gerinnebodens angepaßt ist. Die Schablone (98) ist für ein längs einer Durchmesserlinie des kreisrunden Schachtbodens verlaufendes Gerinne ausgebildet und enthält in Übereinstimmung mit der Schablone (34) den Rand (44) und den Absatz (46). Wie bei der Schablone (34) gehen ebene Flächenabschnitte (54) von muldenförmigen Flächenabschnitten (56) aus, die in der Form an den Boden des Schachtunterteils angepaßt sind. Die ebenen Flächenabschnitte (54) sind einem Teil der beiden Seitenwände eines Gerinnes nachgebildet, der in etwa die halbe Höhe des Gerinnes ausmacht. Der untere Teil des Gerinnes wird mittels des sattelförmigen Abschnitts (102) beim Gießen des Schachtunterteils hergestellt. Der Abschnitt (102) ist entsprechend dem Boden des Gerinnes gewölbt und weist eine Wölbung mit zwei geraden Längsrändern (104) auf, die auf die Enden (106) der Wände der Flächenabschnitte (54) gesetzt werden, um die Schablone (98) zu vervollständigen, d.h. für die Herstellung der Gießform zu montieren. An einem Ende des Abschnitts (102) ist eine sichelförmige Wand (108) in die Wölbung eingesetzt und mit dem sattelförmigen Teil verbunden. Das andere Ende des Abschnitts (102) weist keinen derartigen sichelförmigen Abschnitt auf. Der Abschnitt (100) hat an beiden Enden jeweils eine Wand (110), (111), die über die Enden (106) in einem an die Wölbung des Abschnitts (102) angepaßten Bogen, z.B. halbkreisförmig hinausragt, jedoch um die Stärke der die Flächenabschnitte (54) aufweisenden Wände radial nach innen versetzt ist.Channels on the bottoms of shafts often have to be adjusted in their inclinations from one shaft opening to another to the respective inclination of the sewer pipes adjacent to the shaft. In a further development according to the invention, a template (98) is made available, which is shown in more detail in FIGS. 6 to 8 and consists of a first section (100), which can be used regardless of the slope of the channel bottom, and a second section (102) exists, which is releasably attached to the first section (100) and its inclination is adapted to the desired inclination or the slope of the channel bottom. The template (98) is designed for a channel running along a diameter line of the circular shaft bottom and, in accordance with the template (34), contains the edge (44) and the shoulder (46). As with the template (34), flat surface sections (54) emanate from trough-shaped surface sections (56) whose shape is adapted to the bottom of the manhole base. The flat surface sections (54) are modeled on part of the two side walls of a channel, which makes up approximately half the height of the channel. The lower part of the channel is produced by means of the saddle-shaped section (102) when casting the lower part of the manhole. The section (102) is curved in accordance with the bottom of the channel and has a curvature with two straight longitudinal edges (104), which are placed on the ends (106) of the walls of the surface sections (54) in order to complete the template (98), ie to assemble it for the production of the casting mold. At one end of the section (102), a crescent-shaped wall (108) is inserted into the arch and connected to the saddle-shaped part. The other end of section (102) has no such crescent section. The section (100) has a wall (110), (111) at both ends, which protrudes beyond the ends (106) in an arc, for example semicircular, adapted to the curvature of the section (102), but by the thickness of the Walls having surface sections (54) is offset radially inwards.

An der sichelförmigen Wand (108) ist eine Leiste (112) befestigt, die den inneren konkaven Rand der Wand (108) überragt. Die auf die Außenseite der Wand (108) aufgesetzte, z.B. angeschweißte Leiste (112) erstreckt sich etwa bis zu dem Niveau, das die Längsränder (104) aufweisen, und hat nahe an ihrem freien Ende ein Loch (114), in das eine Schraube (116) eingesetzt wird. Der Abstand in der Mitte zwischen dem äußeren und inneren Rand der sichelförmigen Wand (108) bestimmt das Gefälle, das das Gerinne zwischen den Seitenmuffen hat.A strip (112) is attached to the crescent-shaped wall (108) and projects beyond the inner concave edge of the wall (108). The placed on the outside of the wall (108), e.g. welded strip (112) extends approximately to the level that the longitudinal edges (104) have, and has a hole (114) near its free end into which a screw (116) is inserted. The distance in the middle between the outer and inner edge of the crescent-shaped wall (108) determines the slope that the channel has between the side sleeves.

Die Schablone (98) wird montiert, indem der Abschnitt (102) auf den Abschnitt (100) gesetzt wird. Dabei legen sich die Längsränder (104) des Abschnitts (102) auf die Enden (106) der Wände der Flächenabschnitte (54). Der konkave Rand der sichelförmigen Wand (108) legt sich auf den die Enden (106) überragenden Bogen, z.B. Halbkreis, der Wand (110). Das der sichelförmigen Wand (108) entgegengesetzte Ende des Abschnitts (102) legt sich auf den die Enden (106) überragenden Bogen, z.B. Halbkreis, der Wand (111). In der Wand (110) befindet sich eine Gewindebohrung (118), mit der das Loch (114) bei montiertem Abschnitt (102) fluchtet. Mittels der in das Loch (114) eingesetzten Schraube (116) wird die Leiste (112) und damit der Abschnitt (102) am Abschnitt (100) befestigt.The template (98) is assembled by placing the section (102) on the section (100). The longitudinal edges (104) of the section (102) lie on the ends (106) of the walls of the surface sections (54). The concave edge of the crescent-shaped wall (108) lies on the arch protruding from the ends (106), e.g. Semicircle, the wall (110). The end of the section (102) opposite the sickle-shaped wall (108) lies on the arch projecting over the ends (106), e.g. Semicircle, the wall (111). In the wall (110) there is a threaded hole (118) with which the hole (114) is aligned when the section (102) is mounted. By means of the screw (116) inserted into the hole (114), the strip (112) and thus the section (102) are attached to the section (100).

Die Fig. 7 zeigt die Schablone (98) bzw. Form in montiertem Zustand von vorne. In Fig. 8 ist die Schablone (98) in montiertem Zustand in Seitenansicht dargestellt. Die konkave Innenwand des Abschnitts (102) kann eine Verstärkung (122) aufweisen, wie aus Fig. 8 ersichtlich ist. In der Fig. 8 ist auch deutlich die muldenförmige Ausbildung der Flächenabschnitte (56) zu ersehen, die etwa in der Mitte eine Stelle (124) aufweisen, die einen kürzeren Abstand vom Abschnitt (102) hat als die an die Wände (110), (111) angrenzenden Flächenbereiche.Fig. 7 shows the template (98) or shape in the assembled state from the front. In Fig. 8 shows the template (98) in the assembled state in a side view. The concave inner wall of the section (102) can have a reinforcement (122), as can be seen from FIG. 8. FIG. 8 also clearly shows the trough-shaped design of the surface sections (56), which have a point (124) approximately in the middle, which has a shorter distance from the section (102) than that to the walls (110), (111) adjacent surface areas.

Für verschiedene Gerinneneigungen sind für jeweils den gleichen Schachtdurchmesser verschiedene Abschnitte (102) mit unterschiedlichen sichelförmigen Wänden (108) erforderlich. Die Abstände (120) dieser Wände (102) sind jeweils an die gewünschten Gerinneneigungen angepaßt. Der Abschnitt (100) mit dem übrigen Teil der Schablone (98) ist unabhängig von dem Gerinnegefälle und wird in Verbindung mit dem jeweils benötigten Abschnitt (102) verwendet.For different channel inclinations, different sections (102) with different crescent-shaped walls (108) are required for the same shaft diameter. The distances (120) of these walls (102) are each adapted to the desired channel inclinations. The section (100) with the remaining part of the template (98) is independent of the channel slope and is used in connection with the section (102) required in each case.

Die Schablonen (60) und (74) sind vorzugsweise ebenso wie die Schablone (98) zweiteilig ausgebildet, d.h. die weisen einen vom Gefälle des Gerinnes unabhängigen Abschnitt und einen mit diesem Abschnitt lösbar verbundenen weiteren Abschnitt auf, der jeweils eine das gewünschte Gefälle erzeugende Form hat.The templates (60) and (74), like the template (98), are preferably formed in two parts, i.e. they have a section which is independent of the slope of the channel and a further section which is detachably connected to this section and each has a shape which produces the desired slope.

Die weiteren Abschnitte der Schablonen (60) und (74) sind dabei an ihren Enden in gleicher Weise ausgebildet wie der Abschnitt (102), d.h. das Gefälle wird mit einer sichelförmigen Wand erzeugt, an der sich eine Befestigungsleiste befindet, die an den Stirnseiten des für die Gerinneausbildung vorgesehenen Teils der anderen Abschnitte angeschraubt wird. Die Krümmungen der weiteren Abschnitte der Schablonen (60) und (74) sind dabei an die jeweils gewünschte Gerinneform angepaßt.The further sections of the templates (60) and (74) are formed at their ends in the same way as section (102), i.e. the slope is created with a crescent-shaped wall, on which there is a fastening strip which is screwed onto the end faces of the part of the other sections intended for channel formation. The curvatures of the other sections of the templates (60) and (74) are adapted to the desired channel shape.
