Description

TECHNISCHES GEBIETTECHNICAL AREA

Die Erfindung betrifft einen Tragkorb zum Fertigen eines Schachtbodenteils aus Beton nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a carrier basket for manufacturing a shaft bottom part made of concrete according to the preamble of patent claim 1.

STAND DER TECHNIKSTATE OF THE ART

Bekannte Tragkörbe bestehen in der Regel aus einem zylindrischen, in seinem Durchmesser veränderbaren Grundelement. Dieses Grundelement besitzt vier Kreissegmente, die mehr oder weniger weit nach außen bzw. innen gefahren werden können. An diesen Kreissegmenten, die sämtlich eine gemeinsame zentrale Achse aufweisen, werden außerhalb der Maschine die Halteleisten mit den daran fixierten Formstücken befestigt. Hierzu haben die Kreissegmente an ihren unteren Enden am gesamten Umfang und in kurzen Winkelabständen voneinander Aufnahmestücke, die jeweils um eine horizontale Achse klappbar sind. In diese Aufnahmestücke werden die Halteleisten mit den daran befestigten Formstücken in horizontaler Ausrichtung der Halteleisten eingeschoben und anschließend nach oben in vertikale Ausrichtung hochgeklappt. In dieser nach oben geklappten vertikalen Ausrichtung der Halteleisten besteht also der Tragkorb aus dem Grundelement mit den vier Kreissegmenten und den Halteleisten mit daran passend befestigten Formstücken.Known support baskets are usually made of a cylindrical, variable in diameter element. This basic element has four circle segments, which can be driven more or less far to the outside or inside. At these circle segments, all of which have a common central axis, outside the machine, the retaining strips are fixed with the fittings fixed thereto. For this purpose, the circle segments at their lower ends on the entire circumference and at short angular intervals from each other receiving pieces, which are each hinged about a horizontal axis. In this recording pieces, the retaining strips are inserted with the attached fittings in the horizontal orientation of the retaining strips and then folded upwards in vertical alignment. In this folded-up vertical orientation of the retaining strips thus consists of the support basket of the basic element with the four circular segments and the retaining strips with fittingly attached fittings.

Die Tragleisten des bekannten Tragkorbs sind lose mit den schwenkbaren Aufnahmen der Kreissegmente verbunden. Sie ruhen unter dem Eigengewicht in den nach oben und in die vertikale Position verschwenkten Aufnahmestücken an den Kreissegmenten. Diese lose Befestigung ist für den weiteren Ablauf des bekannten Verfahrens unerläßlich:The support rails of the known basket are loosely connected to the pivotal receptacles of the circle segments. They rest under their own weight in the upward and in the vertical position pivoted receiving pieces on the circle segments. This loose attachment is indispensable for the further course of the known process:

Der Tragkorb mit den von oben in die hochgeschwenkten Aufnahmestücke eingesteckten Halteleisten wird nun in den Formmantel eingefahren oder der Formmantel wird über den Tragkorb gefahren. Der Formmantel besitzt an seinem Umfang verteilt radial in das Innere weisende, zurückziehbare Bolzen mit Kopfplatten. Diese Bolzen mit Kopfplatten sind exakt in der gleichen Anordnung am Umfang vorgesehen, wie die schwenkbaren Halteelemente an den Kreissegmenten. Es befinden sich also die Bolzen an exakt den gleichen Stellen, an denen die Tragleisten angeordnet werden können. In jedem Fall ist damit ein Bolzen, der am Formmantel befestigt ist, an einer Stelle vorgesehen, wo er die dahinter liegende Tragleiste des eingesetzten Tragkorbs übernehmen kann. Ein solches Übernehmen ist deshalb möglich, weil die Tragleisten an ihrem oberen Ende einen achsparallelen Aufnahmeschlitz haben, in die der passende Bolzen beim Absenken bzw. bei der Relativbewegung zwischen Traggestell und Formmantel von oben bis auf das Schlitzende eingefahren werden kann. In dieser von oben eingefahrenen Position wird der eingetauchte Bolzen durch den zugehörigen Hydraulikzylinder, der sich außen am Formmantel befindet, nach außen gezogen. Dabei drückt die Kopfplatte von innen auf die Tragleiste und klemmt diese Tragleiste in der vorgesehenen Position am Formmantel fest. Solche nach innen weisende Bolzen des Formmantels, die kein Widerlager finden, weil sich an ihrer Stelle keine Tragleiste befindet, werden gleichzeitig ebenfalls nach außen gezogen, und zwar in der Weise, daß deren Kopfplatten eine ungestufte Innenkontur mit der Innenwand des Formmantels bilden.The basket with the inserted from above into the swung-up receiving pieces retaining strips is now retracted into the mold jacket or the mold jacket is moved over the basket. The mold shell has distributed on its circumference radially into the interior facing, retractable bolt with head plates. These bolts with head plates are provided exactly in the same arrangement on the circumference, as the pivotable holding elements on the circle segments. So there are the bolts at exactly the same places where the support strips can be arranged. In any case, so that a bolt which is attached to the mold shell, provided at a point where it can take over the underlying support bar of the inserted support basket. Such a takeover is possible because the support strips have at their upper end an axially parallel receiving slot into which the matching bolt when lowering or relative movement between the support frame and mold jacket can be retracted from the top to the end of the slot. In this position retracted from above, the immersed pin is pulled outward by the associated hydraulic cylinder, which is located on the outside of the mold jacket. The top plate presses from the inside on the support bar and clamps this support bar in the intended position firmly on the mold jacket. Such inwardly facing bolts of the mold jacket, which find no abutment, because there is no support bar in their place are also pulled outward at the same time, in such a way that their top plates form an unestimated inner contour with the inner wall of the mold shell.

Sobald die Tragleisten vom Formmantel übernommen worden, also am Formmantel festgeklemmt sind, wird der verbleibende Rest des bekannten Tragkorbs, der aus den Kreissegmenten mit den unteren klappbaren Aufnahmen besteht, nach unten aus dem Formmantel herausgefahren, und zwar in eine Position, in der die Kreissegmente mit neuen Halteleisten bestückt werden können. Nach dem Ausfahren der Kreissegmente erfolgt die Bildung des Ringraums. Hierzu wird der Formkern hochgefahren und der Formmantel mit den angeklemmten Halteleisten über den Formkern abgesenkt. Anschließend erfolgt die Befüllung des Schlitzraums, in dem sich die Halteleisten mit den Formstücken befinden, in der Weise, daß der Boden des Schachtbodenteils nach oben weist. Das offene Ende des Schachtbodenteils wird dabei von einer Untermuffe gebildet.Once the support strips have been taken from the mold shell, so clamped to the mold jacket, the remaining remainder of the known basket basket, which consists of the circle segments with the lower hinged recordings, drove down out of the mold shell, in a position in which the circle segments can be equipped with new retaining strips. After the extension of the circle segments, the formation of the annular space takes place. For this purpose, the mandrel is raised and lowered the mold shell with the clamped retaining strips on the mandrel. Subsequently, the filling of the slot space, in which the retaining strips are located with the fittings, in such a way that the bottom of the shaft bottom portion facing upward. The open end of the shaft bottom part is formed by a lower sleeve.

Sobald das Formteil fertig gerüttelt ist, wird der Formmantel wieder nach oben abgezogen. Hierzu muß zunächst die Klemmwirkung zwischen den Kopfplatten und den Halteleisten aufgehoben werden. Hierzu reicht es, den Betätigungszylinder drucklos zu machen. Es kann dann der Bolzen aus dem vertikalen Aufnahmeschlitz der Halteleisten beim Anheben des Formmantels nach oben herausgleiten.Once the molding is shaken ready, the mold jacket is pulled back up. For this purpose, the clamping action between the top plates and the retaining strips must first be repealed. For this purpose, it is sufficient to depressurize the actuating cylinder. It can then slide out the bolt from the vertical receiving slot of the retaining strips when lifting the mold shell upwards.

Der so gebildete frische Formling enthält nach dem Abnehmen des Formmantels und nach dem Herausziehen des Formkerns die Tragleisten und die an den Tragleisten fixierten Formstükke. Der Formling liegt mit seinem unteren offenen Ende auf der Untermuffe. Es können nun die Tragleisten mit den Formstücken entweder bis zum Aushärten des Formlings am Formling belassen werden oder man kann auch die Tragleisten und die Formstücke im frischen Zustand aus dem Formling entnehmen.The thus-formed fresh molded article contains after removing the mold shell and after pulling out the mold core, the support strips and fixed to the support strips Formstükke. The molding lies with its lower open end on the lower sleeve. It can now be left to the molding either the support strips with the fittings either to cure the molding or you can also remove the support strips and the fittings in the fresh state from the molding.

Aus EP 1 175 983 A2 ist ein Tragkorb nach dem Oberbegriff des Anspruchs 1 bekannt. Der bekannte Tragkorb weist an den Seiten Schalungselemente auf. Zur Formung eines Betonteils muß der bekannte Tragkorb mit einer Formvorrichtung zur Deckung gebracht werden, um die Schalungselemente an die Formvorrichtung zu übergeben.Out EP 1 175 983 A2 is a carrying basket according to the preamble of claim 1 is known. The known carrying basket has on the sides shuttering elements. To form a concrete part of the known basket carrier must be made to coincide with a shaping device to pass the formwork elements to the molding apparatus.

Der vorstehend genannte bekannte Tragkorb läßt sich zusammen mit einer komplexen Maschine verwenden, so daß die Vorrichtung aufwendig und teuer ist.The aforementioned known basket can be used together with a complex machine, so that the device is complicated and expensive.

DIE ERFINDUNGTHE INVENTION

Ausgehend von diesem Stand der Technik liegt der Erfindung die Aufgabe zugrunde, einen Tragkorb der als bekannt vorausgesetzten Art so auszubilden, daß er mit einfachen Fertigungseinrichtungen eine preisgünstige und effektive Fertigung ermöglicht. Gelöst wird diese Aufgabe durch einen Tragkorb mit den Merkmalen des Anspruchs 1.Based on this state of the art, the invention has the object, a support basket of the type assumed to be known form so that it allows a simple and efficient production with simple manufacturing facilities. This object is achieved by a carrying basket with the features of claim 1.

Erfindungsgemäß wird ein fix und fertig außerhalb der Maschine bestückter Tragkorb verwendet, der im unzerlegten Zustand in den Schlitzraum eingeführt wird und darin während der Bildung des Formlings unzerlegt verbleibt. Ein solches Belassen des vormontierten und auch im Montagezustand verbleibenden Tragkorbs unter Verzicht auf das Entfernen der Tragleisten, hat den entscheidenden Vorteil, daß ein derartiger Tragkorb besonders preisgünstig ist. Er bedarf weder irgendwelcher zusätzlicher Elemente am Formmantel, also Spannzylinder und Spannbolzen, noch ist es erforderlich, mit radial verstellbaren Kreissegmenten zu arbeiten. Der durch die Erfindung mögliche Verzicht auf Änderungen sowohl am Formmantel als auch am Formkern schafft einen enormen Vorteil dadurch, daß ein Schachtringfertiger auch zum Fertigen von Schachtböden verwendet werden kann. Hierzu genügt es, den Tragkorb in den Schlitzraum des Schachtringfertigers einzusetzen und im übrigen ähnlich zu arbeiten, wie bei der Fertigung eines Schachtrings. Der einzige Unterschied besteht darin, daß bei der Fertigung eines Schachtbodenteils auf einem Schachtringfertiger statt eines Obermuffenrings eine Obermuffenplatte vorgesehen wird.According to the invention, a carrier basket which is fitted out and ready outside the machine is inserted into the slot space in the un-decomposed state and remains undivided therein during the formation of the shaped article. Such a leave the preassembled and remaining in the mounting state support basket waiving the removal of the support strips, has the distinct advantage that such a basket is particularly inexpensive. He needs neither any additional elements on the mold shell, so clamping cylinder and clamping bolt, nor is it necessary to work with radially adjustable circular segments. The possible by the invention waiver of changes to both the mold shell and the mandrel creates a huge advantage in that a Schachtringfertiger can also be used for the manufacture of manhole bottoms. For this purpose, it is sufficient to use the carrier basket in the slot space of the Schachtringfertigers and otherwise similar to work, as in the production of a chess ring. The only difference is that in the manufacture of a shaft bottom part on a Schachtringfertiger instead of a Obermuffenrings an upper sleeve plate is provided.

Oberhalb des Formkerns 4 ist am Maschinengestell 3 ein Formmantel 6 angeordnet. Die Längsachsen des Formmantels 6 und des Formkerns 4 fluchten miteinander. Formkern 4 und Formmantel 6 bilden gemeinsam einen mit Beton zu befüllenden Schlitzraum.Above the mold core 4, a mold jacket 6 is arranged on the machine frame 3. The longitudinal axes of the mold shell 6 and the mold core 4 are aligned. Mold core 4 and mold jacket 6 together form a concrete space to be filled with slotted space.

Auf einer mit 9 bezeichneten Produkttragplatte befindet sich ein Tragkorb. Dieser Tragkorb, der genauer aus Figuren 2 bis 4 ersichtlich ist, weist vertikale Halteleisten 5a auf. Im dargestellten Ausführungsbeispiel sind insgesamt drei vertikale Halteleisten 5a vorgesehen, die um 90° zueinander versetzt angeordnet sind. Jede Halteleiste 5a trägt ein Formstück 8, mit dem der Durchlaß in der Seitenwand des Schachtbodenteils gebildet wird. Das Formstück 8 erstreckt sich zwischen der Innenwand des Formmantels 6 und der Außenwand des Formkerns 4 quer durch den Schlitzraum.On a designated 9 product carrying plate is a carrying basket. This basket, the more accurate figures 2 to 4 can be seen, has vertical retaining strips 5a. In the illustrated embodiment, a total of three vertical retaining strips 5a are provided, which are arranged offset by 90 ° to each other. Each retaining strip 5a carries a fitting 8, with which the passage is formed in the side wall of the shaft bottom part. The molding 8 extends between the inner wall of the mold shell 6 and the outer wall of the mold core 4 across the slot space.

Die Halteleisten 5a liegen mit ihren unteren Enden auf der ringförmigen Untermuffe 7 auf.The retaining strips 5a lie with their lower ends on the annular lower sleeve 7.

Am oberen Bereich des Tragkorbs ist ein Innenring 5b vorgesehen, der zwei zueinander parallele, horizontale Flansche 5b' und 5b" aufweist. Der Innenring 5b weist radial nach außen offene Nuten 5d auf, und zwar in miteinander fluchtender Anordnung in beiden Flanschen 5b' und 5b".An inner ring 5b having two mutually parallel horizontal flanges 5b 'and 5b "is provided at the upper portion of the support basket 12. The inner ring 5b has radially outwardly open grooves 5d in an aligned arrangement in both flanges 5b' and 5b ".

Zur Sicherung der eingesetzten oberen Endbereiche 5c werden die oberen Endbereiche und der Innenring 5b von einem aufgeschobenen Haltering 5e übergriffen.In the radially outwardly open grooves 5d of the inner ring 5b engage the upper Endbreiche 5c of the retaining strip 5a a form-fitting and non-rotatable. To secure the inserted upper end portions 5c, the upper end portions and the inner ring 5b are overlapped by a deferred retaining ring 5e.

Die Formstücke 8 zur Bildung der Durchlässe sind mittels einer nicht näher dargestellten Verriegelungseinrichtung jeweils an der zugehörigen Halteleiste 5a fixiert. Die Verriegelungseinrichtung besitzt einen Drehriegel 5i, der ein leichtes und schnelles Trennen der Halteleisten 5a von den Formstücken 8 ermöglicht.The fittings 8 for forming the passages are fixed by means of a locking device not shown in each case on the associated retaining strip 5a. The locking device has a rotary latch 5i, which allows a quick and easy separation of the retaining strips 5a of the fittings 8.

Die unteren Enden der Halteleisten 5a besitzen einen elastischen Auflagebereich 5h (siehe Figur 4b), dessen Elastizität durch eine Feder 5g erzeugt wird. Der elastische Bereich 5h stützt sich auf der Untermuffe 7 ab und die Feder 5g kann so weit zusammengedrückt werden, bis der feste Auflagebereich 5f der Halteleiste auf der Untermuffe 7 aufliegt. Der feste Auflagebereich 5f begrenzt also den Verschiebeweg des elastischen Auflagebereichs 5h.The lower ends of the retaining strips 5a have an elastic support region 5h (see FIG. 4b), whose elasticity is generated by a spring 5g. The elastic region 5h is supported on the lower sleeve 7 and the spring 5g can be compressed until the fixed support portion 5f of the retaining strip rests on the lower sleeve 7. The fixed support area 5f thus limits the displacement of the elastic support area 5h.

Der Ablauf des Verfahrens wird nun anhand der Figur 1 im einzelnen beschrieben:The sequence of the method will now be described in detail with reference to FIG. 1:

Der vollständig bestückte Tragkorb wird außerhalb des Schachtringfertigers vorbereitet und in der dargestellten Position auf der Produkttragplatte 9 abgesetzt. Die Produkttragplatte 9 besitzt eine zentrale Durchgangsöffnung 9a. Unmittelbar neben dem Rand der Durchgangsöffnung 9a liegt ein Versteifungsflansch 7a auf der Oberseite der Produkttragplatte 9 auf.The fully loaded carrying basket is prepared outside of the chess manufacturer and placed in the position shown on the product support plate 9. The product support plate 9 has a central through-opening 9a. Immediately adjacent to the edge of the passage opening 9a is a stiffening flange 7a on top of the product support plate 9.

Die Produkttragplatte 9 ist mit dem Maschinengestell 3 verbunden und kann in der Höhe verfahren werden.The product support plate 9 is connected to the machine frame 3 and can be moved in height.

Aus der in Figur 1 ersichtlichen Position wird zunächst der höhenverstellbare Formkern 4 angehoben, bis dessen Oberteil durch die Durchgangsöffnung 9a der Produkttragplatte 9 in den Tragkorb 5 eingreift. Während dieses Vorgangs senkt sich der zuvor angehobene Formkern 4 zeitgleich in seine Fertigungsposition in der Grube. Anschließend wird der Tragkorb 5 zusammen mit der Produkttragplatte 9 so weit auf den angehobenen Formkern 4 abgesenkt, daß die Untermuffe 7 auf dem Rüttelring 4a aufliegt. Danach wird der Formmantel 6 über den Tragkorb 5 und den Formkern 4 abgesenkt. In der abgesenkten Position ist dann der Hohlraum gebildet, der den Beton des Formlings aufnimmt.From the position shown in FIG. 1, the height-adjustable mandrel 4 is first lifted until its upper part engages through the through-opening 9a of the product carrier plate 9 into the carrier basket 5. During this process, the previously raised mandrel 4 lowers simultaneously into its production position in the pit. Subsequently, the support basket 5 is lowered together with the product support plate 9 so far on the raised mold core 4, that the lower sleeve 7 rests on the Rüttelring 4a. Thereafter, the mold jacket 6 is lowered over the support basket 5 and the mandrel 4. In the lowered position, the cavity is then formed, which receives the concrete of the molding.

Während der Befüllung des Hohlraums erfolgt die Verdichtung des Betons durch einen im Formkern 4 befindlichen, nicht dargestellten Zentralrüttler. Nach der Befüllung des Hohlraums wird unter fortwährender Rüttlung mit einer Kolben-Zylinder-Einheit 10 eine in der Zeichnung nicht sichtbare Oberplatte so weit auf den Tragkorb 5 abgesenkt, daß sie mit ihrer Unterseite die Außenwand des Bodens des Schachtbodenteils bilden kann.During the filling of the cavity, the compression of the concrete is carried out by a core 4 located in the core, not shown, central vibrator. After filling the cavity is under continuous shaking with a piston-cylinder unit 10 is not visible in the drawing top plate lowered so far on the carrier basket 5 that it can form the outer wall of the bottom of the shaft bottom part with its bottom.

Zur Entnahme des frischen Formlings werden die Oberplatte und der Formmantel 6 vom Tragkorb 5 nach oben abgezogen und der frische Formling mittels der Produkttragplatte 9 wieder auf das Niveau des Hallenbodens angehoben. Aus der in Figur 1 ersichtlichen Lage wird der frische Formling mit Tragkorb und Untermuffe 7 seitlich neben die Maschine gefahren. In der seitlich neben der Maschine befindlichen Position kann dann der Tragkorb zerlegt werden. Hierzu wird der Haltering 5e nach oben vom Innenring 5b abgezogen. Anschließend können die Halteleisten 5a durch Lösen der Verriegelung von den Formstücken getrennt werden. Das Aushärten des frischen Formlings erfolgt in jedem Fall auf der ringförmigen Untermuffe 7. In welcher Zeit die Zerlegung der übrigen Tragkorbteile erfolgt, hängt von den Betriebsbedingungen, Materialien und anderen Einflußfaktoren ab.For removal of the fresh molded article, the top plate and the mold jacket 6 are removed from the support basket 5 upwards and raised the fresh molded article by means of the product support plate 9 back to the level of the hall floor. From the position shown in FIG. 1, the fresh molded article with carrying basket and lower sleeve 7 is moved laterally next to the machine. In the position located laterally next to the machine, the carrier basket can then be disassembled. For this purpose, the retaining ring 5e pulled up from the inner ring 5b. Subsequently, the retaining strips 5a can be separated by releasing the lock of the fittings. The curing of the fresh molded article takes place in any case on the annular lower sleeve 7. The time during which the decomposition of the remaining basket parts depends on the operating conditions, materials and other factors.

Statt des vorstehend beschriebenen Ablaufs bei der Entschalung gibt es auch andere Möglichkeiten: Wenn der frische Formling vom Formkern 4 gezogen wird, sind die Formstücke 8 mit den Halteleisten verriegelt. Die beim Entschalen auftretende Reibung kann dazu führen, daß der Beton über den Formstücken 8 reißt. In diesem Fall ist es zweckmäßig, in anderer Weise zu Entschalen: Zur Entnahme des frischen Formlings werden die nicht dargestellte Oberplatte, der Formmantel 6, der Tragkorb 5, der Formkern 4 und der frische Formling mit der Produkttragplatte 9 gemeinsam auf das Niveau des Hallenbodens angehoben. Bei diesem Vorgang entsteht keine relative Reibung zwischen den Formteilen. Danach werden die Oberplatte und der Formmantel 6 nach oben abgezogen. Der Formling ist jetzt von außen frei zugänglich. In seinem Inneren befindet sich noch der Formkern 4. In diesem Zustand werden die Verriegelungen zwischen den Formstücken 8 und den Halteleisten 5a gelöst. Anschließend wird der Formkern 4 in die Grube 2 abgesenkt.Instead of the above-described procedure in the demoulding, there are other possibilities: When the fresh molding is pulled from the mold core 4, the fittings 8 are locked with the retaining strips. The friction occurring during demoulding can cause the concrete to break over the fittings 8. In this case, it is expedient to peel in another way: For removal of the fresh molded article, the top plate, the mold jacket 6, the support basket 5, the mandrel 4 and the fresh molded article with the product support plate 9 are not raised together raised to the level of the hall floor , In this process, there is no relative friction between the moldings. Thereafter, the top plate and the mold jacket 6 are pulled upwards. The molding is now freely accessible from the outside. In its interior is still the mold core 4. In this state, the locks between the fittings 8 and the retaining strips 5a are released. Subsequently, the mandrel 4 is lowered into the pit 2.

Schließlich ist auch noch eine weitere Alternative für das Entschalen denkbar. Nach Beendigung des Rüttlungsvorgangs wird der Formmantel 6, in dem sich der frische Formling und der darin befindliche Tragkorb 5 befinden, vom Formkern 4 abgezogen. Anschließend erfolgt das Abziehen des Formmantels 6 mit Anheben der Oberplatte und danach das Zerlegen des Tragkorbs.Finally, another alternative for demoulding is conceivable. After completion of the shaking process, the mold shell 6, in which the fresh molded article and located therein carrying basket 5 are subtracted from the mandrel 4. Subsequently, the removal of the mold jacket 6 takes place with lifting the top plate and then the disassembly of the support basket.

Es ist sowohl möglich, die Zerlegung des Tragkorbs in einem sehr frischen Zustand des Formlings vorzunehmen, als auch erst dann, wenn der Beton des Formlings relativ weit abgebunden hat.It is both possible to carry out the dismantling of the support basket in a very fresh state of the molding, as well as only when the concrete of the molding has set relatively far.

Das Verfahren wurde beschrieben anhand eines Schachtringfertigers. Wenn dieser zur Fertigung von Schachtringen eingesetzt wird, trägt die Kolben-Zylinder-Einheit statt der beschriebenen Oberplatte einen Preßkopf, mit dem eine ringförmige Obermuffe, die den ringförmigen Formraum oben abschließt, aufgedrückt.The method was described using a pawn ring paver. If this is used for the production of manhole rings, carries the piston-cylinder unit instead of the top plate described a pressing head, with an annular upper sleeve, which closes the annular mold space at the top, pressed.

Das beschriebene Verfahren zeigt also, daß mit einem vorhandenen Schachtringfertiger unter Verwendung nur geringer Änderungen, nämlich Oberplatte statt Obermuffe, Schachtbodenteile aus Beton mit seitlichen Auslässen gefertigt werden können.The described method thus shows that with an existing manhole ring paver using only minor changes, namely top plate instead of top sleeve, manhole base parts made of concrete can be made with side outlets.
