Abstract

Der Schacht, dessen Schachtwände aus übereinander angeordneten Wandelementen bestehen, in die Rohreinführungen eingebracht werden können, durch diese wiederum Kabel, Rohrverbänder und/oder Rohre in den Schacht eintreten und/oder den Schacht verlassen können, ist dadurch gekennzeichnet, dass wenigstens eine Wandelement in wenigstens einer Schachtwand in einen oberen und einen unteren Wandelementteil geteilt ist, die lösbar zusammengesetzt sind, wobei die Trennlinie etwa mittig durch das Wandelement verläuft.The shaft, the shaft walls of which consist of wall elements arranged one above the other, into which pipe entries can be made, through which cables, pipe bracings and / or pipes can in turn enter the shaft and / or leave the shaft, is characterized in that at least one wall element is in at least a shaft wall is divided into an upper and a lower wall element part, which are detachably assembled, the dividing line running approximately centrally through the wall element.

Description

Die Erfindung betrifft einen Schacht, dessen Schachtwände aus aus Kunststoff im Spritzgussverfahren hergestellten Wandelementen bestehen, die aufeinander aufgesetzt sind. Meist werden zwei oder drei Reihen von Wandelementen übereinander angeordnet, wobei der obere Abschluss der so gebildeten Schachtwände aus einem aufliegenden Stahlrahmen besteht, in den ein oder mehr Schachtdeckel angeordnet werden. An den Ecken des Schachtes sind die so aus Wandelementen zusammengesetzten Schachtwände aneinander befestigt.The invention relates to a shaft, the shaft walls of which consist of wall elements made of plastic in an injection molding process, which are placed on top of one another. Usually two or three rows of wall elements are arranged one above the other, the upper end of the shaft walls formed in this way consisting of an overlying steel frame in which one or more manhole covers are arranged. The shaft walls thus composed of wall elements are fastened to one another at the corners of the shaft.

Die Wandelemente können integrierte Sollbruchflächen haben, die üblicherweise kreisrund sind und so ausgebildet sind, dass sie bei Bedarf ausbrechbar sind, um Wandöffnungen auszubilden, durch die Kabel, Rohrverbände und/oder Rohre in den Schacht eintreten und/oder den Schacht verlassen können. Wenn die Rohre oder Kabel kleinere Querschnittsabmessungen als die Wandöffnungen haben, durch die sie hindurchgeführt werden, können sie durch Stopfen hindurchgeführt werden, die in die Wandöffnungen eingesetzt werden, so dass die Schachtwände auch an den Wandöffnungen gegen eintretendes Wasser und/oder Sand, Schlamm oder Geröll aus dem Erdreich, in das ein Schacht der betrachteten Art eingelassen ist, abgedichtet ist. Wenn der Durchmesser der Rohre bzw. Kabel mit demjenigen der Wandöffnungen übereinstimmt, entfällt das Erfordernis der Abdichtung durch Stopfen.The wall elements can have integrated predetermined breaking surfaces, which are usually circular and are designed so that they can be knocked out if necessary in order to form wall openings through which cables, pipe assemblies and / or pipes can enter and / or exit the manhole. If the pipes or cables have smaller cross-sectional dimensions than the wall openings through which they are passed, they can be passed through plugs which are inserted into the wall openings so that the shaft walls also protect the wall openings against ingress of water and / or sand, mud or rubble from the ground into which a shaft of the type under consideration is let is sealed. If the diameter of the pipes or cables corresponds to that of the wall openings, there is no need for sealing with plugs.

Es kommt in der Praxis vor, dass dort, wo ein Schacht in das Erdreich eingebaut werden soll, bereits Rohre und/oder Kabel verlaufen. Wenn ein vormontierter Schacht der betrachteten Art auf die Rohre oder Kabel aufgesetzt wird, hat dies zur Folge, dass der Boden des Schachtes schwerlich gegen eintretendes Wasser abgedichtet werden kann. Es ist bei herkömmlichen Schächten der betrachteten Art nicht möglich, die Rohre und/oder Kabel durch Wandöffnungen in den Schachtwänden hindurchzuführen, die durch Bohren oder Ausschneiden der Wandöffnungen oder Ausbrechen von Sollbruchflächen geöffnet werden können.In practice, it happens that pipes and / or cables already run where a shaft is to be built into the ground. If a preassembled shaft of the type under consideration is placed on the pipes or cables, the result is that the bottom of the shaft can hardly be sealed against the ingress of water. With conventional manholes of the type under consideration, it is not possible to pass the pipes and / or cables through wall openings in the manhole walls which can be opened by drilling or cutting out the wall openings or breaking out predetermined breaking surfaces.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, einen Schacht der betrachteten Art so weiter zu entwickeln, dass das obige Problem gelöst ist.The present invention is based on the object of further developing a shaft of the type under consideration in such a way that the above problem is solved.

Diese Aufgabe wird erfindungsgemäß durch die Merkmale des Patentanspruchs 1 gelöst.According to the invention, this object is achieved by the features of claim 1.

Vorteilhafte Ausgestaltungen der Erfindung sind in den Unteransprüchen gekennzeichnet.Advantageous embodiments of the invention are characterized in the subclaims.

Die Erfindung sieht vor, dass wenigstens ein Wandelement in der Einbaulage in einen oberen und einen unteren Wandelementteil geteilt ist, die lösbar zusammengesetzt sind, wobei die Trennlinie etwa mittig durch das Wandelement, bevorzugt durch Sollbruchflächen des Wandelements verläuft. Bevorzugt ist ferner, dass das wenigstens eine geteilte Wandelement das unterste Wandelement einer Schachtwand ist.The invention provides that at least one wall element in the installation position is divided into an upper and a lower wall element part, which are detachably assembled, the dividing line running approximately centrally through the wall element, preferably through predetermined breaking surfaces of the wall element. It is also preferred that the at least one divided wall element is the lowermost wall element of a shaft wall.

Bevorzugt ist dabei, dass die untersten Wandelemente von zwei Schachtwänden, die einander gegenüber liegen, geteilt ausgebildet sind, wobei auch drei oder vier Schachtwände aus Wandelementteilen zusammengesetzt sein können.It is preferred that the lowermost wall elements of two shaft walls that are opposite one another are designed to be divided, with three or four shaft walls also being able to be composed of wall element parts.

Durch diese Ausbildung wird erreicht, dass der Schacht bei seinem Einbau in das Erdreich auf durchlaufende Rohre und/oder Kabel aufgesetzt werden kann, nachdem bevorzugt an den beiden einander gegenüberliegenden kurzen Schachtwänden die unteren Wandelementteile der untersten Wandelemente abgenommen sind. Bei den beiden oberen und unteren Wandelementteilen können nun die im wesentlichen halbierten integrierten Sollbruchflächen herausgebrochen werden, woraufhin die unteren Wandelementteile mit den oberen Wandelementteilen wieder zusammengesetzt werden, wobei die Rohre und/oder Kabel angehoben werden und durch die so gebildeten Wandöffnungen verlaufen. Diese Wandöffnungen können erforderlichenfalls durch Stopfen verschlossen werden, die verbleibende Zwischenräume der Wandöffnung ausfüllen.This design ensures that the shaft can be placed on continuous pipes and / or cables when it is installed in the ground, after the lower wall element parts of the lowermost wall elements have preferably been removed from the two opposite short shaft walls. In the two upper and lower wall element parts, the essentially halved integrated predetermined breaking surfaces can now be broken out, whereupon the lower wall element parts are reassembled with the upper wall element parts, the pipes and / or cables being lifted and running through the wall openings thus formed. If necessary, these wall openings can be closed by stoppers which fill the remaining spaces in the wall opening.

Bevor der vormontierte Schacht auf die beschriebene Weise auf die durchlaufenden Rohre und/oder Kabel aufgesetzt wird, wird eine zugehörige Bodenplatte des Schachtes unter den Rohren und/oder Kabeln positioniert, woraufhin der vormontierte Schacht auf die Bodenplatte aufgesetzt wird.Before the preassembled shaft is placed on the running pipes and / or cables in the manner described, an associated base plate of the shaft is positioned under the pipes and / or cables, whereupon the preassembled shaft is placed on the base plate.

Mit großem Vorteil wird dabei vorgeschlagen, dass der untere Wandelementteil des geteilten Wandelements mit Hilfe von beidseitigen Federverschlüssen lösbar an dem oberen Wandelementteil befestigt ist. Die Federverschlüsse können dabei an seitlichen Rahmenabschnitten des Wandelements befestigt sein. Die Federverschlüsse können so ausgebildet sein, dass sie gegen die Kraft ihrer Federn seitlich von dem unteren Wandelementteil zurückziehbar sind, um das untere Wandelementteil frei zu geben, so dass es abgenommen werden kann. Wenn das untere Wandelementteil wieder befestigt werden soll, wird es auf die seitlichen Rahmenabschnitte aufgesetzt, wobei die Federverschlüsse in dieser Lage durch Federkraft auf den unteren Wandelementteil vorgeschoben werden.It is proposed with great advantage that the lower wall element part of the divided wall element is releasably fastened to the upper wall element part with the aid of spring locks on both sides. The spring locks can be attached to the side frame sections of the wall element. The spring locks can be designed in such a way that they can be laterally withdrawn from the lower wall element part against the force of their springs in order to release the lower wall element part so that it can be removed. When the lower wall element part is to be fastened again, it is placed on the side frame sections, the spring locks in this position are advanced by spring force on the lower wall element part.

Auf diese Weise sind die unteren Wandelementteile ohne die Hilfe von Werkzeugen schnell und einfach abnehmbar und wieder anbringbar, um durchlaufende Rohre und/oder Kabel in ausgewählte Wandöffnungen der unteren Wandelemente der Schachtwände aufzunehmen.In this way, the lower wall element parts can be removed and reattached quickly and easily without the aid of tools in order to accommodate continuous pipes and / or cables in selected wall openings in the lower wall elements of the shaft walls.

Figur 1 zeigt den unteren Bereich einer Schachtwand 1, die aus drei übereinander angeordneten Wandelementen 2, 3 und 4 besteht. Die Wandelemente 2, 3 und 4 sind aus Kunststoff im Spritzgießverfahren hergestellt und haben eine Rippenstruktur, die bei geringem Gewicht den Wandelementen eine hohe Stabilität verleiht. Auf halber Höhe jedes Wandelements sind drei kreisförmige Sollbruchflächen 5 integriert, die ausbrechbar sind, um Wandöffnungen auszubilden, durch die bei Bedarf Rohre, Kabel oder dergleichen in den Schacht eintreten können oder den Schacht verlassen können. Figure 1 shows the lower area of a shaft wall 1, which consists of three wall elements 2, 3 and 4 arranged one above the other. The wall elements 2, 3 and 4 are made of plastic in an injection molding process and have a rib structure that gives the wall elements a high level of stability while being light. Halfway up each wall element, three circular predetermined breaking surfaces 5 are integrated, which can be knocked out to form wall openings train through which pipes, cables or the like can enter the shaft or leave the shaft if necessary.

Das unterste Wandelement 2 ist auf halber Höhe in zwei Wandelementteile 2' und 2" geteilt, wobei die Trennlinie in der Figur mit dem Bezugszeichen 6 bezeichnet ist. Die Trennlinie 6 halbiert im wesentlichen die Sollbruchflächen 5.The lowermost wall element 2 is divided halfway up into two wall element parts 2 ′ and 2 ″, the dividing line being denoted by the reference number 6 in the figure.

Der untere Wandelementteil 2' ist durch einen linken Federverschluss 7 und einen rechten Federverschluss 8 an seitlichen Rahmenabschnitten 9 bzw. 10 befestigt. Mit diesen Federverschlüssen 7, 8 ist der untere Wandelementteil 2' lösbar befestigt, so dass der untere Wandelementteil 2' bei Bedarf abgenommen werden kann, damit die Schachtwand 1 bzw. der gesamte Schacht auf in Bodennähe durchgehende Rohre oder Kabel aufgesetzt werden kann. Nachdem Sollbruchflächen 5 ausgebrochen sind, wird der untere Wandelementteil 2' wieder mit Hilfe der Federverschlüsse 7, 8 an den Rahmenabschnitten 9, 10 befestigt, wobei die Rohre und/oder Kabel so angehoben werden, dass sie durch die Wandöffnungen verlaufen.The lower wall element part 2 ′ is fastened to lateral frame sections 9 and 10 by a left spring lock 7 and a right spring lock 8. With these spring locks 7, 8, the lower wall element part 2 'is releasably attached so that the lower wall element part 2' can be removed if necessary so that the shaft wall 1 or the entire shaft can be placed on pipes or cables extending through near the ground. After predetermined breaking surfaces 5 have broken out, the lower wall element part 2 'is again attached to the frame sections 9, 10 with the aid of the spring locks 7, 8, the pipes and / or cables being raised so that they run through the wall openings.

Figur 2 zeigt den Zustand, in dem der unter Wandelementteil 2' abgenommen wurde. Dabei wird eine aus Metallprofilen bestehende Bodenwand 11 sichtbar, auf die der Schacht aufgesetzt wird. Figure 2 shows the state in which the lower wall element part 2 'has been removed. A bottom wall 11 made of metal profiles, onto which the shaft is placed, becomes visible.

Die Federverschlüsse haben jeweils einen Abschnitt, der unbeweglich an den zugehörigen Rahmenabschnitt 9 oder 10 befestigt ist, und einen beweglichen Verschlussabschnitt, der von einer Feder vorgespannt ist und horizontal zwischen einer Freigabestellung des unteren Wandelementteil 2' und seiner Befestigungslage bewegbar ist. Hierzu greift der in der Figur linke Federverschluss 7 in eine Aussparung 12 und der rechte Federverschluss 8 in eine Aussparung 13 der Rippenstruktur des unteren Wandelementteils 2' ein. Um das untere Wandelementteil 2' abnehmen zu können, schiebt ein Monteur die beiden Federverschlüsse 7, 8 gleichzeitig gegen Federkraft nach rechts bzw. links, wodurch das untere Wandelementteil 2' zur Abnahme freigegeben ist. Zu dessen erneuter Befestigung wird das untere Wandelementteil 2' auf die Federverschlüsse 7, 8 aufgesetzt, wobei durch schräge Wandabschnitte die beiden Federverschlüsse in die Öffnungsstellung verschoben werden und dann, wenn das untere Wandelementteil an den Rahmenelementen 9, 10 anliegt, in die Verschlussstellung einschnappen.The spring locks each have a section which is immovably attached to the associated frame section 9 or 10, and a movable locking section which is pretensioned by a spring and can be moved horizontally between a release position of the lower wall element part 2 'and its fastening position. For this purpose, the spring lock 7 on the left in the figure engages in a recess 12 and the right spring lock 8 in a recess 13 of the rib structure of the lower wall element part 2 '. In order to be able to remove the lower wall element part 2 ', a fitter pushes the two spring locks 7, 8 at the same time against spring force to the right and left, whereby the lower wall element part 2' is released for removal. To re-attach it, the lower wall element part 2 'is placed on the spring locks 7, 8, the two spring locks being moved into the open position by inclined wall sections and then, when the lower wall element part rests against the frame elements 9, 10, snap into the closed position.

Die Figuren 3 und 4 zeigen den rechten Federverschluss 8 zuerst in der Schließstellung und dann in der nach rechts verschobenen Freigabestellung, die durch Pfeile angedeutet ist.the Figures 3 and 4th show the right spring lock 8 first in the closed position and then in the release position shifted to the right, which is indicated by arrows.

Entsprechend zeigen die Figuren 5 und 6 den Federverschluss 7 in der Schließstellung bzw. Blockierstellung und in der nach links zurück gezogenen Freigabestellung.The show accordingly Figures 5 and 6th the spring lock 7 in the closed position or blocking position and in the release position pulled back to the left.

Es wird betont, dass die Erfindung nicht auf die beschriebenen und dargestellten Ausführungsformen beschränkt ist, Vielmehr sind alle offenbarten Merkmale auf jede sinnvolle Weise einzeln miteinander kombinierbar.It is emphasized that the invention is not limited to the described and illustrated embodiments; rather, all of the disclosed features can be individually combined with one another in any meaningful way.
