Abstract

The manhole covering comprises a casing, a base frame and an adjusting device. A two-part base frame has a plurality of bores, which are aligned with pockets located in the base part of the casing. In each pocket is inserted a screw nut, into which is screwed and secured the lower end of a threaded bolt extended through the assigned bore of the base frame. The base frame is adjusted in height and slope by a pair of nuts. The adjustment of a particular slope is made possible due to the shape of the bores, which widen to either end and by convexly curved washers cooperating with the bores at their ends. The screw connection of the base frame constitutes a positive connection, which prevents breaking out of the base frame even in the case of a high, eccentric force application to the manhole covering.

Description

Die Erfindung betrifft eine Schachtabdeckung, insbesondere an Kanalschächten und Wassereinläufen, welcher am oberen Ende eines vorzugsweise senkrechten Schachtes verlegt ist und einen im Boden eingebetteten Rahmen oder ein im Boden eingebettetes Gehäuse und einen Grundrahmen zur Lagerung eines Schachtdeckels oder Schachtrostes aufweist, welcher mit Verstellmitteln versehen ist, mit denen der Grundrahmen in seiner Höhe und in seiner Neigung einstellbar ist.The invention relates to a manhole cover, in particular on manholes and water inlets, which is laid at the upper end of a preferably vertical manhole and has a frame embedded in the floor or a housing embedded in the floor and a base frame for storing a manhole cover or manhole grate, which is provided with adjusting means with which the base frame can be adjusted in height and inclination.

Die Erfindung liegt auf dem Gebiet des Baus und der Abdeckung von Schächten sowie der Ableitung von Regenwasser und anderen Flüssigkeiten von Bauwerken verschiedener Art, insbesondere von befahrenen Strassen, Plätzen und Brücken. Als Deckschicht weisen diese Bauwerke eine Bitumen-, Beton- oder Zementschicht auf, unter welcher ein Unterbau liegt, der aus verschiedenen Materialien, beispielsweise Kies, Sand, Beton od. dgl. bestehen kann. Zwischen dem Unterbau und der Deckschicht wird in verschiedenen Fällen, zum Beispiel bei Brücken und Fahrbahnen, eine Abdichtungsfolie gelegt, um den Unterbau vor dem Eindringen von Feuchtigkeit zu schützen.The invention relates to the construction and covering of shafts and the drainage of rainwater and other liquids from buildings of various types, in particular from streets, squares and bridges used. As a cover layer, these structures have a bitumen, concrete or cement layer, under which there is a substructure, which can consist of different materials, for example gravel, sand, concrete or the like. In various cases, for example in the case of bridges and carriageways, a sealing film is placed between the substructure and the top layer to protect the substructure from the ingress of moisture.

Das auf den genannten Bauwerken anfallende Regenwasser und andere Flüssigkeiten müssen abgeleitet werden, wozu Kanalschächte und Wassereinläufe verschiedener Art verwendet werden. Die Oeffnungen solcher Schächte und Einläufe müssen durch eine Schachtabdeckung abgedeckt werden, die sich im wesentlichen aus einem Schachtrahmen und einem, im Schachtrahmen eingelegten Schachtdeckel oder Schachtrost zusammensetzt. Bei der ersten Verlegung einer solchen Abdeckung wird der Schachtrahmen bündig mit der Bodenoberfläche verlegt, was im Hinblick auf eine ungestörte Begehung oder Befahrung erforderlich ist.The rainwater and other liquids accumulating on the above-mentioned structures must be drained off, using sewer shafts and water inlets of various types. The Openings of such manholes and inlets must be covered by a manhole cover, which essentially consists of a manhole frame and a manhole cover or manhole grate inserted in the manhole frame. When such a cover is laid for the first time, the manhole frame is laid flush with the floor surface, which is necessary with a view to undisturbed inspection or access.

Bei befahrenen Strassen und Plätzen tritt nun das Problem auf, dass die Deckschicht ganz oder teilweise erneuert werden muss. Bei einer solchen Erneuerung kann im allgemeinen das ursprüngliche Niveau der Oberfläche nicht mehr eingehalten werden. Dies bedeutet, dass dann der Schachtrahmen auf das neue Niveau der Deckschicht angehoben oder abgesenkt werden muss. Dies stellt eine recht aufwendige Arbeit dar, die nicht nur mit hohen Kosten verbunden ist, sondern auch eine unerwünschte Beeinträchtigung des Verkehrsflusses mit sich bringt. Dasselbe Problem tritt auch beim Neubau von Strassen auf, denn man kennt gewöhnlich das endgültige Niveau nicht genau. Die Einstellung in der Höhe und in der Neigung kann auch vor oder nach der Verlegung der Deckschicht vorgenommen werden. Dieses Problem ist schon längst erkannt worden, und es hat deshalb nicht an Vorschlägen gefehlt, mit denen der Aufwand und damit die Kosten für eine Neuausrichtung des Schachtrahmen nach erfolgter Verlegung einer neuen Deckschicht gesenkt werden können.The problem now arises on busy streets and squares that the cover layer has to be completely or partially renewed. With such a renewal, the original level of the surface can generally no longer be maintained. This means that the manhole frame must then be raised or lowered to the new level of the top layer. This is a very complex work, which is not only associated with high costs, but also has an undesirable impact on the flow of traffic. The same problem arises when new roads are built, because the final level is usually not known exactly. The height and the inclination can also be adjusted before or after the covering layer has been laid. This problem has long been recognized, and there has therefore been no lack of proposals with which the effort and thus the costs for realigning the shaft frame can be reduced after a new covering layer has been laid.

Ein wesentliches Erfordernis bei solchen verstellbaren Schachtrahmen besteht darin, dass der Schachtrahmen nicht nur in verschiedenen Lagen positioniert, sondern auch zuverlässig gehalten ist, damit er sich nicht, auch bei grösstem darüber rollendem Verkehr, in seiner Lage nach oben verschieben kann.
Auch das Einsetzen und Entfernen der Verstellvorrichtung soll leicht erfolgen können.An essential requirement with such adjustable manhole frames is that the manhole frame is not only positioned in different positions, but is also held reliably so that it cannot shift upwards in its position, even with the heaviest traffic rolling over it.
The insertion and removal of the adjustment device should also be easy.

Hier setzt die Erfindung ein, der die Aufgabe zugrunde liegt, eine Schachtabdeckung der eingangs beschriebenen Art so weiter auszugestalten, dass die Verstellung des Schachtrahmens nicht nur in der Höhe, sondern auch in der Neigung in einfacher Weise einstellbar ist. Diese Aufgabe wird gemäss der Erfindung dadurch gelöst, dass die Verstellmittel drei oder mehr im Grundrahmen verteilte und den Grundrahmen in Bohrungen durchquerende Gewindebolzen sind, die am in dem Rahmen oder in dem Gehäuse, festsitzend abgestützt sind und ein paar Gewindemuttern tragen, welche den Grundrahmen von oben und unten formschlüssig halten und positionieren. Dadurch wird erreicht, dass der Grundrahmen sowohl in der Höhe also auch in seiner Neigung beliebig eingestellt werden kann, ohne dass eine Ausmörtelung des unter dem Grundrahmen liegenden freien Raumes erforderlich ist.This is where the invention comes in, which is based on the object of further developing a manhole cover of the type described at the outset such that the adjustment of the manhole frame can be adjusted in a simple manner not only in height but also in inclination. This object is achieved according to the invention in that the adjusting means are three or more threaded bolts distributed in the base frame and passing through the base frame in bores, which are firmly supported on the frame or in the housing, and carry a pair of threaded nuts which support the base frame from Hold and position positively at the top and bottom. The result of this is that the base frame can be freely adjusted both in height and in its inclination, without the need to fill in the free space underneath the base frame.

Zur Verbesserung der Einstellmöglichkeit ist es zweckmässig, dass zwischen den Schraubenmuttern und dem Grundrahmen Unterlagscheiben angeordnet sind, die auf der gegen den Grundrahmen angerichteten Seitenfläche eine konvexe Wölbung aufweisen. Damit wird ein klemmfreies Einstellen einer bestimmten Neigung des Grundrahmens gewährleistet. Die Neigungseinstellung kann zudem erweitert werden, wenn die Bohrungen für die Gewindebolzen im Grundrahmen gegen die beiden Enden mit einer konischen Erweiterung versehen sind.To improve the setting possibility, it is expedient that washers are arranged between the screw nuts and the base frame, which have a convex curvature on the side surface directed against the base frame. This ensures that a certain inclination of the base frame is set without jamming. The inclination setting can also be expanded if the holes for the threaded bolts in the base frame are provided with a conical extension against the two ends.

Zwei Ausführungsbeispiele der Erfindung sind in der Zeichnung dargestellt und nachfolgend beschrieben. Es zeigen:

  • Fig. 1 einen Vertikalschnitt einer schematischen, teilweisen Darstellung einer Schachtabdeckung,
  • Fig. 2 einen Schnitt längs der Linie II-II in Fig. 1 und
  • Fig. 3 einen Vertikalschnitt einer schematischen, teilweisen Darstellung einer weiteren Schachtabdeckung.
Two embodiments of the invention are shown in the drawing and described below. Show it:
  • 1 is a vertical section of a schematic, partial representation of a manhole cover,
  • Fig. 2 shows a section along the line II-II in Fig. 1 and
  • Fig. 3 is a vertical section of a schematic, partial Representation of another manhole cover.

Die in Fig. 1 dargestellte Schachtabdeckung setzt sich aus einem Gehäuse 1, einem in das Gehäuse einführbaren Grundrahmen 2 und Verstellmitteln 3 zusammen. Das Gehäuse 1 kann auch einen Aussenflansch 4 aufweisen, an den sich ein annähernd senkrechter oder mit einer Neigung versehener Wandteil 5 anschliesst. Am unteren Ende des Wandteils 5 schliesst ein Bodenteil 6 an, in dessen Mitte ein Ablauf 7 mit einem Ablaufstutzen 8 angeordnet ist. Wird das Gehäuse 1 für die Ableitung von Bodenwasser beispielsweise in einer Brücke oder an einem Flachdach verwendet, das heisst an einer Stelle, wo nur ein verhältnismässig dünner Unterbau vorliegt, kann der Ablauf 7 auch seitlich am Wandteil 5 vorgesehen werden.The shaft cover shown in FIG. 1 is composed of a housing 1, a base frame 2 which can be inserted into the housing and adjusting means 3. The housing 1 can also have an outer flange 4, which is adjoined by an approximately vertical or inclined wall part 5. At the lower end of the wall part 5 there is a bottom part 6, in the middle of which an outlet 7 with an outlet connector 8 is arranged. If the housing 1 is used for draining soil water, for example in a bridge or on a flat roof, that is to say at a point where there is only a relatively thin substructure, the outlet 7 can also be provided on the side of the wall part 5.

Im Bodenteil 6 sind in der Nähe des Wandteils 5 Taschen 9 vorgesehen, welche nach oben teilweise durch eine Ausnehmung 10 geöffnet sind. Die Taschen 9, von denen mindestens drei am Innenumfang des Wandteils 5 angeordnet sind, weisen eine rechteckige Form auf (Fig. 2), während die Ausnehmung 10 Schlitzform mit einem gerundeten Grund aufweist. Im Bereich der Taschen 9 kann der Bodenteil 6 eine grössere Wandstärke aufweisen, die sich über den ganzen Innenumfang des Gehäuses 1 erstreckt oder nur örtlich vorgesehen werden kann.In the bottom part 6 5 pockets 9 are provided in the vicinity of the wall part, which are partially opened upwards by a recess 10. The pockets 9, of which at least three are arranged on the inner circumference of the wall part 5, have a rectangular shape (FIG. 2), while the recess 10 has a slot shape with a rounded base. In the area of the pockets 9, the base part 6 can have a greater wall thickness, which extends over the entire inner circumference of the housing 1 or can only be provided locally.

In Fig. 1 ist der Grundrahmen 2 aus zwei Teilen zusammengesetzt, von denen der eine Teil als Grundrahmenoberteil 11 und der andere Teil als Grundrahmen und Unterteil 12 ausgebildet ist. Es ist jedoch auch möglich, den Grundrahmen 2 aus einem Stück herzustellen. Die Unterteilung in Oberteil 11 und Unterteil 12 erfolgt aus praktischen Gründen, beispielsweise zur Vereinfachung der Herstellung. Der Grundrahmenoberteil 11 und der Grundrahmenunterteil 12 können auch miteinander fest verbunden sein, beispielsweise durch Verschrauben oder Schweissen (nicht dargestellt).In Fig. 1, the base frame 2 is composed of two parts, one part of which is designed as a base frame upper part 11 and the other part as a base frame and lower part 12. However, it is also possible to manufacture the base frame 2 from one piece. The division into upper part 11 and lower part 12 is done for practical reasons, for example to simplify the manufacture. The base frame upper part 11 and the base frame lower part 12 can also be firmly connected to one another, for example by screwing or welding (not shown).

Im Grundrahmenunterteil 12 sind senkrechte Bohrungen 13 eingearbeitet. Die Bohrungen 13 können zylindrische Form oder wie in Fig. 1 dargestellt ist, eine nach beiden Seiten sich erweiternde Trichterform aufweisen. Die Zahl der Bohrungen 13 stimmt mit der Zahl der Taschen 9 überein und zudem fluchten die Bohrungen 13 mit den Taschen 9.Vertical bores 13 are machined in the base frame lower part 12. The bores 13 can have a cylindrical shape or, as shown in FIG. 1, a funnel shape that widens on both sides. The number of holes 13 coincides with the number of pockets 9 and, moreover, the holes 13 are aligned with pockets 9.

Durch die Bohrungen 13 erstreckt sich ein Schraubenbolzen 14, dessen unteres Ende 15 durch die Ausnehmungen 10 in die Taschen 9 ragt. In den Taschen 9 ist eine Schraubenmutter 16 eingelegt, deren Aussenkontur rechteckig oder quadratisch ist und mit geringem Seitenspiel in die Tasche 9 passt. Wird nun das untere Ende 15 des Schraubenbolzen 14 in die Schraubenmutter 16 eingeschraubt, kann sich die Schraubenmutter 16 nicht in der Tasche 9 drehen, so dass sie soweit auf das untere Ende 15 aufgeschraubt werden kann, bis sie an der Decke der Tasche 9 satt anliegt und eine feste Verbindung mit dem Bodenteil 6 bildet.A screw bolt 14 extends through the bores 13, the lower end 15 of which projects through the recesses 10 into the pockets 9. In the pockets 9, a screw nut 16 is inserted, the outer contour of which is rectangular or square and fits into the pocket 9 with little side play. If the lower end 15 of the screw bolt 14 is now screwed into the screw nut 16, the screw nut 16 cannot rotate in the pocket 9, so that it can be screwed onto the lower end 15 until it fits snugly against the ceiling of the pocket 9 and forms a firm connection with the bottom part 6.

Auf den Schraubenbolzen 14 wird ein Paar Schraubenmuttern 17,18 geschraubt, von denen die eine Schraubenmutter 17 auf der Unterseite und die andere Schraubenmutter 18 auf der Oberseite des Grundrahmenunterteils 12 liegt. Zwischen den Schraubenmuttern 17,18 und dem Grundrahmenunterteil ist je eine Unterlagscheibe 19 eingelegt, deren gegen den Grundrahmenunterteil 12 gerichtete Seitenfläche bombiert, das heisst mit einer konvexen Kugelfläche 20 versehen ist.A pair of screw nuts 17, 18 are screwed onto the screw bolts 14, of which one screw nut 17 lies on the underside and the other screw nut 18 lies on the upper side of the base frame lower part 12. Between the screw nuts 17, 18 and the base frame lower part, a washer 19 is inserted, the side surface of which is directed toward the base frame lower part 12, that is to say is provided with a convex spherical surface 20.

Die Verstellmittel 3, das heisst die Schraubenbolzen 14, die Schraubenmuttern 17,18 und die Unterlagsscheiben 19, erlauben eine exakte Einstellung der Höhe des Grundrahmens 2. Aber auch eine bestimmte Neigung kann durch die kugeligen Flächen 20 der Unterlagsscheiben 19 und durch die nach beiden Seiten sich erweiternden Partien der Grundrahmen 2 klemmfrei eingestellt werden.The adjustment means 3, that is, the bolts 14, the nuts 17, 18 and the washers 19, allow an exact adjustment of the height of the base frame 2. But also a certain inclination can be achieved by the spherical surfaces 20 of the washers 19 and by the two sides expanding parts of the base frame 2 can be adjusted without jamming.

Am oberen Ende 22 des Schraubenbolzens 14 kann eine Innensechskant-, eine Kreuzschlitzbohrung 21 oder ein Schlitz zum Anziehen des Schraubenbolzens 14 mit einem entsprechenden Schlüssel oder Schraubenzieher vorgesehen werden. Das obere Ende 22 kann jedoch auch als Aussensechskant ausgebildet sein.At the upper end 22 of the screw bolt 14, a hexagon socket, a cross-slot bore 21 or a slot for tightening the screw bolt 14 can be provided with an appropriate key or screwdriver. However, the upper end 22 can also be designed as an external hexagon.

Die in Fig. 3 dargestellte Schachtabdeckung weist dieselben Verstellmittel 3 auf wie die Schachtabeckung nach Fig. 1, weshalb die gewählten Bezugszeichen dieselbe Bedeutung wie in Fig. 1 besitzen. Auch die Befestigung der Schraubenbolzen 14 im Grundrahmen 2 erfolgt in derselben Weise wie bei der Schachtabdeckung nach Fig. 1. In der Nebenfigur von Fig. 2 ist eine weitere Befestigung der Schraubenbolzen 14 dargestellt, bei der die Fixierung derselben mit einer Abstützung 16′, z.B. einer Schulter, einem Stellring oder einer Kontermutter erfolgt.The manhole cover shown in FIG. 3 has the same adjustment means 3 as the manhole cover according to FIG. 1, which is why the chosen reference symbols have the same meaning as in FIG. 1. The fastening of the screw bolts 14 in the base frame 2 is carried out in the same way as for the manhole cover according to FIG. a shoulder, a collar or a lock nut.

Der Unterschied liegt darin, dass bei der Ausführung nach Fig. 3 der Grundrahmen 2 einteilig ausgebildet ist, der anstelle des Gehäuses 1 in Fig. 1 in einem Rahmen 23 angeordnet ist, welcher das obere Ende eines senkrechten Schachtes 24 abgrenzt. Der Rahmen 23 weist am Aussenumfang angeordnete Rippen 25 auf, wobei sein schachtseitiges Ende einen Aussenflansch 26 und einen Innenflansch 27 grösserer Wandstärke aufweist, in welch letzteren auch die Taschen 9 für Befestigung der Schraubenbolzen 14 liegen.The difference is that in the embodiment according to FIG. 3, the base frame 2 is formed in one piece, which is arranged in place of the housing 1 in FIG. 1 in a frame 23 which delimits the upper end of a vertical shaft 24. The frame 23 has ribs 25 arranged on the outer circumference, its shaft-side end having an outer flange 26 and an inner flange 27 of greater wall thickness, in which the pockets 9 for fastening the screw bolts 14 also lie.

Sowohl bei der Schachtabdeckung nach Fig. 1 als auch nach Fig. 3 ist der obere Rand des Grundrahmens 2 als Sitz 30 ausgebildet, in welchem ein Schachtdeckel oder ein Schachtrost (nicht dargestellt) eingesetzt werden kann.1 and 3, the upper edge of the base frame 2 is designed as a seat 30, in which a manhole cover or a manhole grate (not shown) can be used.

Die beiden beschriebenen, in ihrer Höhe und ihrer Neigung einstellbaren Schachtabdeckungen nach Fig. 1 und 2 weisen eine einfache Konstruktion auf. Der Grundrahmen 2 kann mittels der Schraubenmuttern 17,18 exakt eingestellt werden, wobei die Schraubenmutter 18 als Kontermutter eine Verschiebung der Lage des Grundrahmens 2 auch bei grossen Belastungen und exzentrischem Kraftangriff verhindert. Dasselbe gilt auch für die Verschraubung der Schraubenbolzen 14 im Bodenteil 6 des Gehäuses 1 beziehungsweise im Innenflansch 27 des Rahmens 23.The two described, in height and inclination adjustable manhole covers according to FIGS. 1 and 2 have a simple construction. The base frame 2 can by means of Screw nuts 17, 18 can be set exactly, the screw nut 18, as a lock nut, preventing the position of the base frame 2 from shifting even under high loads and eccentric force application. The same also applies to the screwing of the screw bolts 14 in the base part 6 of the housing 1 or in the inner flange 27 of the frame 23.

Die Zahl der Schraubenbolzen bestimmt sich auf Grund der Grösse der Schachtabdeckung und der aufzunehmenden Belastung. Der Hohlraum unter dem Grundrahmen 2 kann ggf. ausgemörtelt werden; was aber nicht erforderlich ist.The number of bolts is determined by the size of the manhole cover and the load to be borne. The cavity under the base frame 2 can optionally be mortared; but this is not necessary.

Dadurch, dass der Grundrahmen 2 in dem Gehäuse 1 angeordnet ist, kann das Gehäuse 1 für sich allein verlegt und der Grundrahmen 2 nachträglich eingesetzt werden. Dies erleichtert das Verlegen der Schachtabdeckung in den Boden.Because the base frame 2 is arranged in the housing 1, the housing 1 can be installed on its own and the base frame 2 can be used subsequently. This makes it easier to lay the manhole cover in the ground.
