Description

Die Erfindung bettrift 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 are made of plastic injection-molded wall elements that are placed one on top of the other. Two or three rows of wall elements are usually arranged one above the other, with the upper end of the shaft walls formed in this way consisting of a steel frame on which one or more manhole covers are arranged. The shaft walls composed of wall elements are fastened to one another at the corners of the shaft.

Die Wandelemente haben integrierte Sollbruchflächen, 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 have integrated breakaway surfaces, which are usually circular and are designed to be broken out if necessary to form wall openings through which cables, tubing bundles and/or pipes can enter and/or exit the duct. If the pipes or cables have smaller cross-sectional dimensions than the wall openings through which they pass, they can be passed through plugs that are inserted into the wall openings, so that the shaft walls also at the wall openings against ingress of water and/or sand, mud or Rubble from the ground, in which a shaft of the type under consideration is embedded, is sealed. If the diameter of the pipes or cables matches that of the wall openings, the need for sealing with plugs is eliminated.

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, there are already pipes and/or cables running where a shaft is to be installed in the ground. If a pre-assembled manhole of the type under consideration is placed on the pipes or cables, this has result in the bottom of the shaft being difficult to seal against the ingress of water. With conventional shafts of the type under consideration, it is not possible to guide the pipes and/or cables through wall openings in the shaft walls, which can be opened by drilling or cutting out the wall openings or by breaking out predetermined breaking surfaces.

Die EP 2 631 370 A2 offenbart einen Schacht, dessen Schachtwände aus übereinander angeordneten Wandelementen bestehen, in die Rohreinführungen eingebracht werden können, durch die wiederum Kabel, Rohrverbände und/oder Rohre in den Schacht eintreten und/oder den Schacht verlassen können, wobei wenigstens einige Wandelemente integrierte Sollbruchflächen haben, die ausbrechbar sind, um Wandöffnungen für Kabel und/oder Rohre auszubilden, wobei wenigstens ein 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, und wobei das wenigstens eine geteilte Wandelement das unterste Wandelement einer Schachtwand ist. Zur Verbindung der übereinander angeordneten Wandelementteile werden Drehriegel eingesetzt, die vertikal verlaufende, zueinander fluchtende Durchgangsöffnungen in den Wandelementteilen durchgreifen.The EP 2 631 370 A2 discloses a shaft, the shaft walls of which consist of wall elements arranged one above the other, into which pipe entries can be introduced, through which in turn cables, pipe bundles and/or pipes can enter and/or leave the shaft, with at least some wall elements having integrated predetermined breaking surfaces which can be broken out in order to form wall openings for cables and/or pipes, with at least one wall element in at least one shaft wall being divided into an upper and a lower wall element part which are detachably assembled, with the dividing line running approximately centrally through the wall element, and with the at least a split wall element is the lowest wall element of a shaft wall. To connect the wall element parts arranged one above the other, rotary bolts are used, which pass through vertically running, mutually aligned through-openings in the wall element parts.

Die KR 100 543 660 B1 schlägt zur Befestigung von geteilten Wandelementteilen eine Niet- und Bolzenverbindung vor.The KR 100 543 660 B1 proposes a rivet and bolt connection for fastening divided wall element parts.

Die KR 100 949 742 B1 schlägt zur Festlegung einer Schachtabdeckung eine Feder-Bolzen-Konstruktion vor, wobei die Druckschrift keinen Hinweis auf den Einsatz dieser Konstruktion als Wandverbinder gibt.The KR 100 949 742 B1 proposes a spring-bolt construction for fixing a manhole cover, with the publication giving no indication of the use of this construction as a wall connector.

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 patent claim 1 .

Vorteilhafte Ausgestaltungen der Erfindung sind in den Unteransprüchen gekennzeichnet.Advantageous developments of the invention are characterized in the dependent claims.

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. Erfindungsgemäß ist das wenigstens eine geteilte Wandelement das unterste Wandelement einer Schachtwand.The invention provides that at least one wall element is divided in the installed position into an upper and a lower wall element part, which are releasably assembled, the dividing line running approximately centrally through the wall element, preferably through predetermined breaking surfaces of the wall element. According to the invention, the at least one divided wall element is the lowest 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 lie opposite one another are designed to be divided, it also being possible for three or four shaft walls 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 means 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 lowest wall elements are preferably removed from the two opposite short shaft walls. The two upper and lower wall panel parts can now have the substantially bisected integrated frangible surfaces broken out, whereupon the lower wall panel parts are reassembled with the upper wall panel parts, with the pipes and/or cables being lifted and passing through the wall openings thus formed. If necessary, these wall openings can be plugged be closed, filling the remaining gaps 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 manhole is placed onto the running pipes and/or cables in the manner described, an associated bottom plate of the manhole is positioned under the pipes and/or cables, whereupon the preassembled manhole is placed on the bottom plate.

Erfindungsgemäß ist außerdem vorgesehen, 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.According to the invention, it is also provided that the lower wall element part of the divided wall element is detachably 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 pulled back laterally from the lower wall element part against the force of their springs in order to free the lower wall element part so that it can be removed. If the lower wall element part is to be fastened again, it is placed on the side frame sections, with the spring locks in This position can be advanced by spring force on the lower part of the wall element.

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 member parts can be quickly and easily removed and reattached without the aid of tools to accommodate passing pipes and/or cables in selected wall openings of the lower wall members 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 using the injection molding process and have a ribbed structure which gives the wall elements high stability while being lightweight. Halfway up each wall element, three circular predetermined breaking surfaces 5 are integrated, which can be broken out around wall openings form, through which pipes, cables or the like can enter the shaft or can leave the shaft if required.

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 bottom 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. The dividing line 6 essentially bisects the predetermined breaking surfaces 5.

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 by a left spring fastener 7 and a right spring fastener 8 to side frame sections 9 and 10, respectively. The lower wall element part 2' is detachably fastened with these spring locks 7, 8 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 running through near the ground. After frangible surfaces 5 have been broken out, the lower wall element part 2' is reattached to the frame sections 9, 10 by means of the spring fasteners 7, 8, the pipes and/or cables being lifted so that they pass 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 consisting of metal profiles becomes visible, on which the shaft is placed.

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.The spring latches each have a portion immovably fixed to the associated frame portion 9 or 10 and a movable latch portion which is spring biased and movable horizontally between a release position of the lower panel part 2' and its fixed position. For this purpose, the spring fastener 7 on the left in the figure engages in a recess 12 and the right spring fastener 8 engages in a recess 13 of the ribbed structure of the lower wall element part 2'.

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.In order to be able to remove the lower wall element part 2', a fitter pushes the two spring locks 7, 8 simultaneously against spring force to the right or left, as a result of which the lower wall element part 2' is released for removal. To fasten it again, the lower wall element part 2' is placed on the spring locks 7, 8, with the two spring locks being pushed into the open position by inclined wall sections and then snapping into the closed position when the lower wall element part rests against the frame elements 9, 10.

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 4 show the right spring lock 8 first in the closed position and then in the released position, which is shifted to the right and 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 6 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 im Rahmen des Schutzbereichs der Ansprüche miteinander kombinierbar.It is emphasized that the invention is not limited to the described and illustrated embodiments, but all disclosed features can be combined with each other in any reasonable way within the scope of the claims.
