Description

Die Erfindung bezieht sich auf Verfahren und Vorrichtungen zur Herstellung von Schachtunterteilen mit variablen Gerinneausführungen mit den Merkmalen im Oberbegriff des Anspruches 1 und 16.The invention relates to methods and apparatus for producing manhole bases with variable Gerinneausführungen with the features in the preamble of claim 1 and 16.

Betonfertigteile wie Rohre, Schachtelemente und Schachtunterteile werden in großen Stückzahlen mit weitgehend automatisierten Anlagen hergestellt. Dabei wird der Beton bei gleichzeitiger Rüttlung in die Form eingefüllt und verdichtet. Zusätzlich erfolgt eine weitere Formgebung und Verdichtung durch das Einpressen der Obermuffe im Bereich der Formeinfüllöffnung. Anschließend erfolgt sofort die Entschalung und der Weitertransport der frischen Betonteile auf Profilringe oder Paletten. Mit dem Rüttelpressverfahren lassen sich alle Massenprodukte gleicher Form und Struktur rationell herstellen. Schachtunterteile sind ebenfalls Massenprodukte, wobei jedoch das Gerinne eine Variantenvielfalt aufweißt, die eine automatische rationelle Produktion bisher nicht zulässt.Precast concrete parts such as pipes, manhole elements and manhole bases are produced in large numbers with largely automated systems. The concrete is poured into the mold with simultaneous shaking and compacted. In addition, there is a further shaping and compression by the pressing of the upper sleeve in the region of the Formeinfüllöffnung. Subsequently, the demoulding and the further transport of the fresh concrete parts to profile rings or pallets takes place immediately. With the vibrating press process, all mass products of the same shape and structure can be produced efficiently. Manhole bases are also mass products, but the channel has a variety of variants, which does not allow automatic rational production so far.

Bei einem bekannten Verfahren gemäß DE 696 04 961 T2 wird das Schachtelement vor dem Bohren der seitlichen Öffnungen mit einem härtbaren Füllmaterial gefüllt. Nach ausreichender Erhärtung dieses Füllmaterials wird das Gerinne von oben herausgefräst. Nachteilig hierbei ist, dass das Schachtunterteil nicht monolithisch in einem Guss hergestellt ist und mindestens zwei Vorgänge für das Betonieren des Schachtes erforderlich sind. Außerdem dauert der Fräsvorgang von oben sehr lange, da größere Mengen Beton oder Füllmaterial abgetragen und entfernt werden müssen.In a known method according to DE 696 04 961 T2 For example, the well element is filled with a curable filler prior to drilling the side openings. After sufficient hardening of this filler, the channel is milled from above. The disadvantage here is that the manhole base is not monolithically produced in one casting and at least two operations for concreting the shaft are required. In addition, the milling process from the top takes a very long time, as larger amounts of concrete or filler material must be removed and removed.

Bei einem weiteren Verfahren gemäß DE 198 28 094 C1 wird ein Schachtunterteil-Rohling durch Verdichten des erdfeuchten Betons geformt. Nach dem Entschalen des Schachtunterteil-Rohlings steht dieser mit seiner dicken Sohlplatte (Bodenplatte) auf dem Untergrund. In dieser Position wird in den noch erdfeuchten (noch nicht erhärteten) Beton mittels eines Fräswerkzeugs ein Rohgerinne gefräst. Nachteilig ist, dass der Fräsvorgang durch den abgetragenen Beton stark beeinträchtigt wird und die Gerinneoberfläche beschädigt wird. Das Absaugen des abgefrästen, noch erdfeuchten Betons ist nur zum Teil möglich und sehr aufwendig. Durch das Entschalen im Wendeverfahren des Schachtunterteil-Rohlings aus noch erdfeuchtem Beton und das Herausziehen der Aussparkerne und das Fräsen des Rohgerinnes entstehen am Spitzende Deformierungen (Unebenheiten), welche die Dichtheit und Statik des Schachtbauwerks beeinträchtigen. DE 198 28 094 C1 offenbart deswegen ein Verfahren und eine Vorrichtung zu Herstellung von Schlachtunterteilen gemäß dem Oberbegriff der Ansprüche 1 und 16.In another method according to DE 198 28 094 C1 For example, a manhole blank is formed by compacting the earth-moist concrete. After demoulding the manhole base blank, it stands with its thick base plate (base plate) on the ground. In this position, a raw channel is milled into the still earth-moist (not yet hardened) concrete by means of a milling tool. The disadvantage is that the milling process is greatly affected by the removed concrete and the channel surface is damaged. The suction of the milled, still earth-moist concrete is only partially possible and very expensive. By demoulding in the turning process of the manhole base blank from still earth-moist concrete and the extraction of the Ausspar cores and the milling of the Rohgerinnes arise at the spigot deformations (Bumps), which affect the tightness and statics of the shaft structure. DE 198 28 094 C1 discloses therefore a method and an apparatus for producing slaughter bases according to the preamble of claims 1 and 16.

Bei einem weiteren Verfahren gemäß DE 103 17 321 A1 wird für jedes Gerinne ein Modell aus Styropor hergestellt. Dieses Modell wird in den Gießformen befestigt und anschließend der flüssige Beton eingegossen. Die Entschalung erfolgt nachdem der Beton weitgehend abgebunden ist und die erforderliche Festigkeit aufweist. Das Modell wird nach dem Entschalungsvorgang zerstört. Nachteilig bei diesem Verfahren ist, dass es nur für das Gießverfahren geeignet ist. Es werden also sehr viele Formen benötigt, deren Handhabung aufwendig ist und die hohe Investitionen voraussetzen. Die Herstellung der Modelle kann nicht vollkommen automatisiert werden. Es bleibt also noch viel Handarbeit übrig. Die Materialkosten für die verlorenen Modelle sind sehr hoch. Eine wirtschaftliche rationelle Fertigung mit diesem Verfahren ist nicht gegeben.In another method according to DE 103 17 321 A1 For each channel a Styrofoam model is produced. This model is fixed in the molds and then poured the liquid concrete. The demoulding takes place after the concrete has largely set and has the required strength. The model is destroyed after the demoulding process. A disadvantage of this method is that it is only suitable for the casting process. So it requires a lot of forms, their handling is complex and require high investment. The production of the models can not be completely automated. So there is still a lot of manual work left. The material costs for the lost models are very high. An economic rational production with this method is not given.

In der Regel werden deshalb die Gerinne manuell nachträglich in Schachtunterteilrohlinge eingebracht. Diese Arbeit ist anstrengend und zeitaufwendig. Die Kosten liegen jedoch immer noch weit unter den Kosten für die bisherigen bekannten Verfahren.As a rule, therefore, the channels are manually introduced later in manhole base blanks. This work is exhausting and time consuming. However, the cost is still far below the cost of the previous known methods.

Die Aufgabe ist bei dem Verfahren, der im Oberbegriff des Anspruches 1 definierten Art gemäß der Erfindung, durch die Merkmale im Kennzeichnungsteil des Anspruches 1 gelöst.The object is achieved in the method defined in the preamble of claim 1 according to the invention, by the features in the characterizing part of claim 1.

Die Herstellung der Schachtunterteile, jedoch noch ohne variablem Gerinne, erfolgt im Rüttelpressverfahren oder Gießverfahren. Hierbei werden die Schachtunterteile in umgekehrter natürlicher Lage in Formeinrichtungen hergestellt. Das Herstellen der variablen Gerinne erfolgt durch schichtweises Abtragen von Beton ebenfalls in umgekehrter natürlicher Lage. Der Beton kann schnell und ohne großen Energieaufwand abgetragen werden, weil der Beton nur zum Teil erhärtet ist. Der abgetragene Beton fällt durch die Schwerkraft nach unten, sodass der Fräsvorgang selbst durch die Betonreste nicht behindert wird. Der Betonabtrag wird aufgefangen und zur Weiterverwertung verwendet. Die Schachtunterteile sind monolithisch aus einem Guss hergestellt. Zur Herstellung der Gerinne werden keine Modelle benötigt. Der gesamte Fertigungsablauf kann mit diesem Verfahren automatisiert werden. Die Gerinne selbst sind maßgenau und können strömungstechnisch optimiert ausgeführt werden. Es sind beliebige Formen der Gerinne machbar. Die Spitzenden der Schachtunterteile sind sehr maßgenau, da die Schachtunterteile auf den Profilringen in umgekehrter natürlicher Lage abbinden.The production of the manhole bases, but still without variable flume, takes place in the vibrating or casting process. Here, the manhole bases are made in reverse natural position in molds. The production of the variable channel is done by stratified removal of concrete also in reverse natural position. The concrete can be removed quickly and without much energy, because the concrete is only partially hardened. The removed concrete falls down by gravity, so that the milling process itself is not hindered by the concrete residues. The concrete removal is collected and used for further processing. The manhole bases are made monolithically from a single casting. For the production of the channels no models are needed. The entire production process can be automated with this procedure. The channels themselves are dimensionally accurate and can be designed to be optimized in terms of flow. Any forms of channels are possible. The spigots of the manhole bases are very accurate, as the manhole bases on the profile rings set in the reverse natural position.

Die Erfindung bezieht sich auf Schachtunterteile 1 aus Beton, die in umgekehrter natürlicher Lage in Formen 19 gerüttelt oder gegossen werden. Das variable Gerinne 3 wird dabei jedoch noch nicht hergestellt, sondern lediglich die komplette Auftrittsfläche ohne Gerinne 13, die in der Regel kegelförmig ist. In diesen Formeinrichtungen 19 sind auch die Aussparkerne 10 für die Zuläufe und den Ablauf eingebracht. Das variable Gerinne 3 wird in einem zweiten Arbeitsgang durch Betonabtrag 4 hergestellt, wobei sich auch das Schachtunterteil bei diesem Vorgang in umgekehrter natürlicher Lage befindet, sodass in kurzer Zeit große Mengen Beton abgetragen werden können, der durch die Schwerkraft nach unten fällt und den Fräsvorgang nicht behindert. Wie im schematischen Schnitt der Figur 1 dargestellt wird der rotierende Fräser 5 geführt und programmgesteuert 18 über die Betonoberfläche geführt und der Beton 4,14,16 somit schichtweise abgefräst.The invention relates to manhole bases 1 made of concrete, which are shaken or cast in reverse natural position in molds 19. However, the variable channel 3 is not yet made, but only the complete tread surface without channel 13, which is usually conical. In these mold devices 19 and the Aussparkerne 10 are introduced for the inlets and the drain. The variable channel 3 is produced in a second operation by concrete removal 4, whereby the manhole base is in this process in reverse natural position, so that in a short time large quantities of concrete can be removed, which falls by gravity down and not the milling process with special needs. As shown in the schematic section of Figure 1, the rotating cutter 5 is guided and guided programmatically 18 on the concrete surface and the concrete 4,14,16 thus milled in layers.

Gemäß Figur 2 ist die Formeinrichtung 19 zur Herstellung der Schachtunterteile noch ohne Gerinne zu sehen. Die Form kann sowohl für das Gießverfahren mit selbstverdichtendem Beton 16, als auch für das Rüttelpressverfahren für Beton 14 ausgelegt werden.According to FIG. 2 is the molding device 19 for producing the manhole bases still seen without flumes. The mold can be designed both for the self-compacting concrete pouring method 16 and for the concrete vibrating compacting method 14.

Mit der Vertikalhubeinrichtung 44, die in vorteilhafter Weise mit einem Hydraulikzylinder 45 betätigt wird, wird der Stützkern 11 mit dem Deckel 12 und dem Profilring 6 vertikal in den Formmantel 9 abgesenkt und nach erfolgtem Füll- und Verdichtungsvorgang des Betons 14; das Schachtunterteil 1 nach oben ausgestoßen.With the Vertikalhubeinrichtung 44, which is actuated in an advantageous manner with a hydraulic cylinder 45, the support core 11 is lowered with the lid 12 and the profile ring 6 vertically into the mold jacket 9 and after completion of filling and compacting process of the concrete 14; the manhole base 1 is ejected upwards.

Gemäß Anspruch 2 erfolgt das Abtragen des Betons 4,14,16 im Bereich der variablen Gerinne 3 nach einer Teilerhärtung von 1 bis 10 Stunden. Erst nach einer Teilerhärtung von 1 bis 3 Stunden kann der Deckel 12 vom Schachtunterteil 1 entfernt werden, sodass die Auftrittsfläche ohne Gerinne 13 zur Betonabtragung 4 zugänglich ist. Die Teilerhärtung kann beschleunigt werden, indem die Schachtunterteile 1 durch eine Härterkammer geführt werden.According to claim 2, the removal of the concrete 4,14,16 takes place in the region of the variable channel 3 after a Teilerhärtung from 1 to 10 hours. Only after a Teilerhärtung of 1 to 3 hours, the cover 12 can be removed from the manhole base 1, so that the tread surface without channel 13 for concrete removal 4 is accessible. The Teilerhärtung can be accelerated by the manhole bases 1 are passed through a hardener chamber.

Das Schneidwerkzeug 47 rotiert nicht wie der Fräser 5, sondern schneidet ganze Schichten und Stücke aus dem teilerhärteten Beton heraus.The cutting tool 47 does not rotate like the cutter 5 but cuts whole layers and pieces out of the partially cured concrete.

Gemäß Anspruch 3 ist dargelegt, dass der Betonabtrag 4 durch mindestens einen rotierenden Fräser 5 erfolgt. Der Fräser 5 hat einen Durchmesser von ca. 140 mm und ist bestückt mit 8 bis 40 Hartmetallzähnen. Der Fräser 5 kann sowohl links als auch rechts rotieren und arbeiten. Mit dem Fräser 5 können Betonmengen 4 von etwa 0,1 bis 1,0 dcm3 pro Sekunde abgetragen werden, sodass ein variables Gerinne 3 innerhalb von 3 bis 10 Minuten herausgefräst ist. Der teilerhärtete Beton 14,16 kann schnell und mit geringer Antriebsleistung und geringem Verschleiß abgetragen werden.According to claim 3, it is stated that the concrete removal 4 is effected by at least one rotating cutter 5. The cutter 5 has a diameter of approx. 140 mm and is equipped with 8 to 40 carbide teeth. The cutter 5 can rotate and work both left and right. With the cutter 5, concrete quantities 4 of about 0.1 to 1.0 dcm 3 per second can be removed so that a variable channel 3 is milled out within 3 to 10 minutes. The hardened concrete 14,16 can be removed quickly and with low drive power and low wear.

Gemäß Anspruch 4 wird das Schachtunterteil 1 in umgekehrter natürlicher Lage auf Profilringe 6 gehalten, dies ermöglicht einen sicheren Transport und eine genaue Position der Schachtunterteile 1 beim Fräsen. Außerdem entstehen dadurch sehr maßhaltige Spitzenden. Die Profilringe 6 werden erst nach endgültigem Aushärten der Schachtunterteile 1 vom Spitzende entfernt. Unter umgekehrter natürlicher Lage des Schachtunterteils 1 ist zu verstehen, dass das Spitzende 30 waagerecht oder schräg nach unten zeigt.According to claim 4, the manhole base 1 is held in reverse natural position on profile rings 6, this allows for safe transport and accurate position of the manhole bases 1 during milling. In addition, this creates very accurate spikes. The profile rings 6 are removed only after final curing of the manhole bases 1 from the spigot end. Under reverse natural position of the manhole base 1 is to be understood that the spigot 30 shows horizontally or obliquely downwards.

Gemäß Anspruch 5 ist dargelegt, dass die variablen Gerinne 3 programmgesteuert 18 in jeder verlangten geometrischen Vielfalt herstellbar sind. Die Maßhaltigkeit und Geometrie der variablen Gerinne 3 ist sehr genau, da die teilerhärteten Schachtunterteile 1 bereits formstabil sind. Der Betonabtrag 4 der teilerhärteten Schachtunterteile 1 erfolgt in wesentlich höherer Geschwindigkeit als bei ausgehärteten Schachtunterteilen 1.According to claim 5 it is stated that the variable channels 3 can be produced program-controlled 18 in any desired geometric diversity. The dimensional accuracy and geometry of the variable channel 3 is very accurate, since the semi-hardened manhole bases 1 are already dimensionally stable. The concrete removal 4 of the part-hardened manhole bases 1 takes place at a substantially higher speed than with hardened manhole bases 1.

Gemäß Anspruch 6 wird das Schachtunterteil 1 in vorteilhafter Weise aus feinkörnigem Material hergestellt. Dies hat den Vorteil, dass beim Abfräsen des teilerhärteten Betons eine möglichst saubere Oberfläche erzielt wird, die zusätzlich durch einen nachfolgenden Glättvorgang besser geglättet werden kann, als der Beton, der üblicher Weise für Schachtunterteile verwendet wird. Bisher wird ein Beton für Schachtunterteile verwendet, mit einer Korngröße bis 16 mm. Insgesamt gesehen, werden alle Oberflächen des Schachtunterteiles durch Verwendung des feinkörnigen Betons besser.According to claim 6, the manhole base 1 is advantageously made of fine-grained material. This has the Advantage that the best possible clean surface is achieved when milling the partially cured concrete, which can be better smoothed by a subsequent smoothing process, in addition to the concrete that is commonly used for manhole bases. So far, a concrete is used for manhole bases, with a grain size up to 16 mm. Overall, all surfaces of the manhole base are better by using the fine-grained concrete.

Gemäß Anspruch 7 werden die variablen Anschlüsse, die bereits bei der ersten Formgebung in Formen hergestellt wurden, vermessen und aufgrund dieser Daten wird das Fräsprogramm für die dazu passenden variablen Gerinne erzeugt. Dies hat den Vorteil, dass das variable Gerinne 3 zu den variablen Anschlüssen 2 sehr maßgenau fluchtet.According to claim 7, the variable terminals, which have already been manufactured in molds during the first shaping, are measured and on the basis of these data the milling program for the matching variable channels is produced. This has the advantage that the variable channel 3 is aligned very accurately to the variable terminals 2.

Gemäß Anspruch 8 und 9 werden die variablen Anschlüsse 2 nicht mehr bei der ersten Formgebung durch die Aussparkerne 10 hergestellt und geformt, sondern ebenfalls mit der Fräsvorrichtung aus dem teilerhärteten Beton ausgefräst. Der Industrieroboter 22 ist so angeordnet, dass er mit dem Fräser 5 sowohl die variablen Gerinne, als auch alle variablen gefrästen Anschlüsse fräsen kann. Hierzu wird zusätzlich das Schachtunterteil um seine vertikale Achse 34 gedreht, sodass am gesamten Umfang des Schachtunterteiles variabel gefräste Anschlüsse angebracht werden können.According to claim 8 and 9, the variable terminals 2 are no longer manufactured and formed in the first shaping by the Aussparern 10, but also milled with the milling device of the partially cured concrete. The industrial robot 22 is arranged so that with the milling cutter 5 it can mill both the variable channels and all the variable milled connections. For this purpose, the manhole base is also rotated about its vertical axis 34, so that variable milled connections can be attached to the entire circumference of the manhole base.

Gemäß Anspruch 10 wird die Oberfläche des variablen Gerinnes unmittelbar nach dem Fräsvorgang glattgestrichen. Um die Glättwirkung zu verbessern, kann zusätzlich Wasser aufgespritzt werden.According to claim 10, the surface of the variable channel is smoothed immediately after the milling process. In order to improve the smoothing effect, additional water can be sprayed on.

Gemäß Anspruch 11 wird unmittelbar nach dem Fräsvorgang eine Flüssigkeit aufgespritzt. Dies erfolgt programmgesteuert, in sehr gleichmäßiger und exakter Schichtdicke.According to claim 11, a liquid is sprayed immediately after the milling process. This is program-controlled, in a very even and exact layer thickness.

Gemäß Anspruch 12 wird die Oberfläche des variablen Gerinnes 3 durch Sandstrahlen nachbehandelt. Dabei kann zusätzlich auch die Auftrittsfläche 41 sandgestrahlt werden, sodass eine rutschhemmende, aufgeraute Oberfläche sowohl im variablen Gerinne 3 als auch auf der Auftrittsfläche 41 entsteht.According to claim 12, the surface of the variable channel 3 is aftertreated by sandblasting. In this case, in addition, the tread surface 41 may be sandblasted, so that a slip-resistant, roughened surface is formed both in the variable channel 3 and on the tread surface 41.

Gemäß Anspruch 13 ist dargelegt, dass der Betonabtrag 4, der in großen Mengen in kurzer Zeit anfällt, selbsttätig durch die Schwerkraft entfernt wird, nämlich durch Herabfallen in einen Behälter 7. Der Weitertransport dieses Betonabtrages 4 ist einfach, zum Beispiel über ein Förderband 8, sodass diese Betonreste 4 in der Fertigungsmaschine oder Mischanlage weiter verwertet werden können.According to claim 13 it is stated that the concrete removal 4, which occurs in large quantities in a short time, is automatically removed by gravity, namely by falling into a container 7. The further transport of concrete removal 4 is easy, for example via a conveyor belt 8, so that these concrete residues 4 can be further utilized in the production machine or mixing plant.

Die Erfindung umfasst ferner eine Vorrichtung zur Herstellung von Schachtunterteilen mit den Merkmalen des unabhängigen Anspruchs 16.The invention further comprises an apparatus for producing manhole bases with the features of independent claim 16.

Die Aussparkerne 10 sind am Formmantel 9 variabel befestigt, sodass jeder Anschlusswinkel realisiert werden kann. Der Stützkern 11 weist einen Deckel 12 zur Bildung des Auftrittes 13 auf, jedoch im ersten Arbeitsgang also bei der Herstellung ohne Gerinne, wobei der Deckel 12 flach oder kegelförmig ist. In die Vorrichtung ist die Fräsvorrichtung 17 und / oder die Schneidvorrichtung 46 integriert, die das variable Gerinne 3 nach einer Teilerhärtung von ca. 1 bis 10 Stunden herausarbeitet.The Aussparkerne 10 are variably attached to the mold jacket 9, so that each connection angle can be realized. The support core 11 has a lid 12 for the formation of the appearance 13, but in the first operation so in the production without channel, wherein the lid 12 is flat or conical. In the device, the milling device 17 and / or the cutting device 46 is integrated, which works out the variable channel 3 after a Teilerhärtung of about 1 to 10 hours.

Gemäß Anspruch 19 ist die Formeinrichtung 19 so ausgeführt, dass der Beton 14 durch Rütteln der Formeinrichtung 19 verdichtet wird und gegebenenfalls durch zusätzliches Einpressen der Pressplatte 15. Beim so genannten Rüttelpressverfahren hat der Beton 14 schon eine so große Grünstandsfestigkeit, dass sofort nach dem Verdichtungsvorgang der Formmantel 9 und die Pressplatte 15 entfernt werden können. Anschließend werden die Aussparkerne 10 herausgezogen, sodass diese ebenfalls gleich wieder verwendet werden können. Bei der Verwendung von integrierten Dichtungen in den Anschlüssen 2 verbleiben lediglich noch Aufsteckkerne 20 bis zum endgültigem Abbinden im Betonteil. Das Schachtunterteil 1 wird auf dem Profilring 6 gemeinsam mit dem Stützkern 11 und dem Deckel 12 weiter transportiert und gegebenenfalls durch eine Härtekammer geführt, sodass die Teilerhärtung schneller erfolgt.According to claim 19, the molding device 19 is designed so that the concrete 14 is compacted by shaking the molding device 19 and optionally by additional pressing of the pressing plate 15. In the so-called Rüttelpressverfahren the concrete 14 already has such a large green strength, that immediately after the compression process of Form jacket 9 and the pressing plate 15 can be removed. Subsequently, the Aussparkerne 10 are pulled out, so that they can also be used immediately again. When using integrated seals in the terminals 2 remain only Aufsteckkerne 20 until the final setting in the concrete part. The manhole base 1 is further transported on the profile ring 6 together with the support core 11 and the lid 12 and optionally passed through a curing chamber, so that the Teilerhärtung takes place faster.

Nach ca. 1 bis 5 Stunden wird der Stützkern 11 mit dem Deckel 12 herausgezogen und das Schachtunterteil 1 steht nur noch auf dem Profilring 6, sodass das variable Gerinne 3 durch schichtweises Herausfräsen und / oder Herausschneiden des Betons 4,14,16 hergestellt werden kann.After about 1 to 5 hours, the support core 11 is pulled out with the lid 12 and the manhole base 1 is only on the profile ring 6, so that the variable channel 3 can be made by layering out and / or cutting out of the concrete 4,14,16 ,

Gemäß Anspruch 20 werden mehrere Formeinrichtungen 19 benötigt, die mit selbstverdichtendem Beton 16 befüllt werden. Nach der gewünschten Teilerhärtung des Betons 16 können die Stützkerne 11, die Deckel 12 und die Aussparkerne 10 entfernt werden, sodass auch hier das Schachtunterteil 1 nur noch auf dem Profilring 6 in umgekehrter natürlicher Lage steht und auch hier das variable Gerinne 3 schnell und problemlos herausgefräst werden kann.According to claim 20, a plurality of mold devices 19 are required, which are filled with self-compacting concrete 16. After the desired Teilerhärtung of the concrete 16, the support cores 11, the cover 12 and the Aussparkerne 10 can be removed so that here the manhole base 1 is only on the profile ring 6 in the reverse natural position and also the variable channel 3 milled out quickly and easily can be.

Gemäß Anspruch 21 wird das Schachtunterteil 1 relativ zum Formmantel 9 nach oben entformt. Dies erfolgt mit der Vertikalhubeinrichtung 44, die das Schachtunterteil 1 samt Stützkern 11, Deckel 12, Profilring 6 und Aussparkernen 11 nach oben aus dem Mantel 9 herausschiebt. Dies ist ein sehr einfacher und sicherer Entschalungsvorgang und das Schachtunterteil 1 ist zum Herausnehmen der Aussparkerne 11 und zum Weitertransport von oben sehr gut zugänglich.According to claim 21, the manhole base 1 is removed from the mold 9 relative to the top. This is done with the Vertikalhubeinrichtung 44, which pushes the manhole base 1 together with the support core 11, cover 12, profile ring 6 and Aussparkernen 11 upwards out of the jacket 9. This is a very simple and safe demoulding process and the manhole base 1 is very accessible for removing the Aussparkerne 11 and for further transport from the top.

Gemäß Anspruch 23 erfolgt das Drehen des Profilrings 6 samt Schachtunterteil 1 mit mindestens drei Bundrollen 26 und elektrischem Drehantrieb. Es besteht auch die nicht gezeigte Variante, dass zu jedem Drehantrieb mehrere Bundrollen zugeordnet sind, die dann zur Aufnahme von Schachtunterteilen 1 mit verschiedenen Nenndurchmessern, z. B. Nennweite 1000, 1200 und 1500 mm ausgelegt sind.In accordance with claim 23, the turning of the profile ring 6 together with manhole base 1 with at least three flange rollers 26 and electric rotary drive. There is also the variant, not shown, that for each rotary drive a plurality of coil rollers are assigned, which then for receiving shaft bottoms 1 with different nominal diameters, z. B. nominal width 1000, 1200 and 1500 mm are designed.

Gemäß Anspruch 24 ist eine Messeinrichtung 27 vorgesehen, zum Vermessen der vorgefertigten variablen Anschlüsse 2. Hierzu wird das Schachtunterteil 1 um seine vertikale Achse 34 gedreht und mit der Messeinrichtung die Umfangsfläche des Schachtunterteiles 1, entweder durch Ultraschall oder durch Laserstrahlen, abgetastet. Damit können die Messdaten der variablen Gerinne 3 in Bezug auf Durchmesser, Höhenlage und Winkel exakt erfasst werden, sodass das Herausfräsen des variablen Gerinnes 3 gemäß den Istabmessungen der Anschlüsse 2 erfolgt.According to claim 24, a measuring device 27 is provided for measuring the prefabricated variable connections 2. For this purpose, the manhole base 1 is rotated about its vertical axis 34 and scanned with the measuring device, the peripheral surface of the manhole base 1, either by ultrasound or by laser beams. Thus, the measurement data of the variable channel 3 with respect to diameter, altitude and angle can be accurately detected, so that the milling out of the variable channel 3 according to the actual dimensions of the terminals 2 takes place.

Gemäß Anspruch 25 wird der rotierende Fräser 5 und / oder das Schneidwerkzeug mit dem Industrieroboter 22 programmgesteuert geführt. Üblicher Weise hat ein solcher Industrieroboter sechs Achsen. Damit lassen sich das variable Gerinne 3, als auch variabel gefräste Anschlüsse 24 schnell und exakt aus dem teilerhärteten Beton 14, 16 ausfräsen. Durch die Anordnung des Industrieroboters 22 unterhalb und seitlich zu dem Schachtunterteil 1 kann sowohl außen als auch innen im Schachtunterteil 1 gefräst werden und der Betonabtrag 4 kann frei in die Auffangwanne 29 herunter fallen.According to claim 25, the rotating cutter 5 and / or the cutting tool is guided programmatically with the industrial robot 22. Usually, such an industrial robot has six axes. Thus, the variable channel 3, as well as variably milled connections 24 can be quickly and accurately milled from the partially cured concrete 14, 16. Due to the arrangement of the industrial robot 22 below and laterally to the manhole base 1 can both outside and inside in Manhole base 1 are milled and the concrete removal 4 can fall freely into the sump 29 down.

Gemäß Anspruch 26 ist der rotierende Fräser 5 mit Hartmetall oder Diamantzähnen bestückt. Die Schneidkanten 38 dieser Zähne tangieren eine gedachte Kugel 36.According to claim 26 of the rotating cutter 5 is fitted with carbide or diamond teeth. The cutting edges 38 of these teeth affect an imaginary sphere 36.

Gemäß Anspruch 27 und 28 kommt ein Schneidwerk 47 zum Einsatz, das mit der Schneidkante den feinkörnigen, teilerhärteten Beton 14, 16 schichtweise herausschneidet. Der Betonabtrag 4 wird dabei nicht zerkleinert und wird in großen Mengen und mit noch geringerem Verschleiß abgetragen. Die Schneidkante besteht vorzugsweise aus einem dünnen Blech und ist kreisförmig. Das Schneidwerkzeug 47 ist einfach und kostengünstig und das Verschleißblech 49 kann schnell gewechselt werden.According to claims 27 and 28, a cutting unit 47 is used, which cuts the fine-grained, semi-hardened concrete 14, 16 in layers with the cutting edge. The concrete removal 4 is not crushed and is removed in large quantities and with even less wear. The cutting edge is preferably made of a thin sheet and is circular. The cutting tool 47 is simple and inexpensive and the wear plate 49 can be changed quickly.

Gemäß Anspruch 29 und 30 ist die Glättkugel 23 etwas größer als die gedachte Kugel 36 des rotierenden Fräsers 5. Damit kann für den Glättvorgang nahezu noch mal das gleiche Programm abgefahren werden, wie beim Fräsvorgang. Lediglich die Vorschubgeschwindigkeit und Drehzahl der Glättkugel 23 wird variiert. Durch die Durchmesserdifferenz der Glättkugel 23 zum Fräser 5 wird der Anpressdruck beim Glätten auf dem Beton vorgegeben.According to claim 29 and 30, the smoothing ball 23 is slightly larger than the imaginary ball 36 of the rotating cutter 5. Thus, almost the same program can be traversed for the smoothing process, as in the milling process. Only the feed rate and speed of the smoothing ball 23 is varied. Due to the difference in diameter of the smoothing ball 23 to the cutter 5, the contact pressure is set when smoothing on the concrete.

Bei dem gemäß erfindungsgemäßem Verfahren und erfindungsgemäßer Vorrichtung hergestellten Schachtunterteil 1 handelt es sich um ein monolithisches Teil, das homogen aus Beton hergestellt ist. Sowohl das Gerinne als auch die Schachtwand ist aus einem Stück gegossen oder gerüttelt. Es wird ein feinkörniger Beton 14, 16 verwendet. Korngröße etwa 0 - 4 mm. Dieser Beton 14, 16 lässt sich in vorteilhafter Weise gut verarbeiten und ist besonders gut für das neue automatische Fertigungsverfahren geeignet. Das gesamte Schachtunterteil 1 hat eine gleichmäßige feine Oberflächenstruktur.The manhole base 1 produced in accordance with the method and device according to the invention is a monolithic part which is manufactured homogeneously from concrete. Both the channel and the shaft wall are cast or vibrated in one piece. It is a fine-grained concrete 14, 16 used. Grain size about 0 - 4 mm. This concrete 14, 16 can be processed well in an advantageous manner and is particularly well suited for the new automatic manufacturing process. The entire manhole base 1 has a uniform fine surface structure.

Das variable Gerinne 3 weist aufgrund des neuen Verfahrens eine Formgenauigkeit und Oberfläche auf, die bisher nicht möglich war. Dies insbesondere durch den exakten maschinellen automatischen Fräsvorgang bei teilerhärtetem, feinkörnigen Beton 14, 16.The variable channel 3 has due to the new process on a dimensional accuracy and surface that was previously not possible. This is particularly due to the exact automatic automatic milling process in the case of semi-hardened, fine-grained concrete 14, 16.

Die variablen Gerinne 3 können gemäß dem neuen Verfahren durch eine weitere Nachbehandlung verbessert werden können, insbesondere auch deshalb, weil durch die programmgesteuerte Bearbeitung exakte Daten über die Geometrie des Gerinnes 3 vorhanden sind und so eine weitere automatische Bearbeitung der Teile möglich wird.The variable channels 3 can be improved according to the new method by a further treatment, in particular also because the program-controlled processing exact data on the geometry of the channel 3 are present and so a further automatic machining of the parts is possible.

Auch wird das variable Gerinne 3 nach vollständigem Aushärten der Schachtunterteile 1 und Wenden in natürlicher Lage, zur Verbesserung der Oberfläche mit einer Beschichtung oder mit Mörtel versehen, oder die Oberfläche des Gerinnes 3 wird durch Schleifen oder Fräsen weiter verbessert. Hierbei muss nur noch eine dünne Schicht abgetragen werden, da bereits ein geometrisch einwandfreies Gerinne 3 vorhanden ist, das lediglich noch geglättet wird.Also, the variable channel 3 after complete curing of the manhole bases 1 and turning in a natural position, the Improvement of the surface provided with a coating or mortar, or the surface of the channel 3 is further improved by grinding or milling. In this case, only a thin layer has to be removed, since a geometrically perfect channel 3 is already present, which is merely smoothed.

Das variable Gerinne 3 und auch die Auftrittsfläche 41 können durch Sandstrahlen nachbehandelt werden. Dadurch entsteht eine aufgeraute, rutschsichere Struktur.The variable channel 3 and also the tread surface 41 can be aftertreated by sandblasting. This creates a roughened, non-slip structure.

Durch das neue Fertigungsverfahren lassen sich sehr maßhaltige Teile erzielen.The new manufacturing process can achieve very dimensionally stable parts.

Die Gerinnekanäle 43 sind strömungstechnisch optimal ausgeführt, durch eine einfache Gesetzmäßigkeit, die besagt, dass die Gerinnekanalachsen 42 immer Radien (R) sind, die in etwa senkrecht auf die Achsen der Anschlüsse 2, 24 treffen, bzw. senkrecht auf die innere Schachtwand auftreffen. Diese einfache Gesetzmäßigkeit lässt es zu, dass nur aufgrund der Position und des Durchmessers der Anschlüsse 2, 24, das Fräsprogramm automatisch erzeugt und berechnet werden kann, sodass der Programmieraufwand für das Fräsprogramm gering ist. Der Fräsvorgang selbst wird in vorteilhafter Weise durch einen Industrieroboter 22 durchgeführt. Dieser kann zusätzlich auch Anschlüsse 24 von außen in den teilerhärteten Beton 14, 16 fräsen und auch die Nachbehandlung der Schachtunterteile 1 übernehmen, wie z. B. Glätten und Beschichten oder auch Beschriften. The channel channels 43 are optimally designed in terms of flow, by a simple law, which states that the channel channel axes 42 are always radii (R), which meet approximately perpendicular to the axes of the terminals 2, 24, or perpendicular to the inner shaft wall. This simple law allows only because of the position and the diameter of the terminals 2, 24, the milling program can be automatically generated and calculated, so that the programming effort for the milling program is low. The milling process itself is advantageously performed by an industrial robot 22. This can additionally connections 24 from the outside in the semi-hardened concrete 14, 16th mill and also take over the treatment of the manhole bases 1, such. B. smoothing and coating or labeling.
