Abstract

The frame (1) is composed of a pipe section (2) and a marginal part (3) arranged on the outside of the pipe section (2) and projecting outwards. Provided on the inside of the pipe section (2) are projections (4) on which a cover or grating can be supported. The marginal part (3) is designed as a cohesive collar which projects horizontally outwards. The marginal part (3) is arranged at a height (h) below the top margin (8), the height (h) being one third to one half of the overall height (H) of the pipe section (2). Owing to the fact that the marginal part (3) is arranged at a distance from the top margin (8) of the pipe section (2), it will be surrounded on all sides by the material of the roadway paving when the frame (1) is installed, as a result of which the frame (1) is solidly connected to the ground material and cannot be substantially displaced by the traffic flow. <IMAGE>

Description

Die Erfindung betrifft einen Rahmen einer Abdeckung für eine Oeffnung, die durch einen im Rahmen gelagerten Deckel oder Rost geschützt ist, wobei der Rahmen als Rohrstück mit im wesentlichen senkrechter Achse ausgebildet ist und eine Umrandung der Oeffnung bildet.The invention relates to a frame of a cover for an opening, which is protected by a lid or grate mounted in the frame, the frame being designed as a tube piece with a substantially vertical axis and forming a border of the opening.

Die Erfindung betrifft das Gebiet von Einrichtungen, das als Zubehör von Strassenanlagen bezeichnet werden kann. Darunter sind beispielsweise Schachtabdeckungen zur Abdeckung von Schächten, Kanälen und Abläufen zu verstehen. Solche Abdeckungen können jedoch auch auf Plätzen, in Höfen, aber auch in Böden von Gebäuden verwendet werden und dienen dort zum Schutz von Mannlöchern, Kontrollschächten u.dgl. Solche Abdeckungen sind in vielen Ausführungen bekannt und setzen sich im wesentlichen aus einem Rahmen und einem in dem Rahmen eingesetzten Deckel oder Rost zusammen. Insbesondere kann der Rahmen in sehr verschiedener Weise ausgeführt sein, was vor allem vom Einsatzort abhängt. Im wesentlichen besteht der Rahmen aus einem Rohrstück mit einer im wesentlichen senkrecht verlaufenden Rohrachse, an dem eine Auflage für den Deckel oder Rost angeordnet ist. Der Querschnitt des Rohrstückes kann kreisförmig, oval, quadratisch, rechteckig, dreieckig u.dg. sein.The invention relates to the field of facilities, which can be referred to as accessories for road systems. This includes, for example, manhole covers to cover manholes, channels and drains. However, such covers can also be used in squares, in courtyards, but also in the floors of buildings, where they serve to protect manholes, inspection shafts and the like. Such covers are known in many designs and essentially consist of a frame and a lid or grate inserted in the frame. In particular, the frame can be designed in very different ways, which mainly depends on the place of use. The frame essentially consists of a piece of pipe with a substantially vertical pipe axis, on which a support for the cover or grate is arranged. The cross section of the pipe section can be circular, oval, square, rectangular, triangular and the like. be.

Unabhängig von der Form des Querschnittes des Rahmens stellt sich das Problem, den Rahmen zuverlässig in dem umgebenden Bodenbereich so einzubauen, dass er sozusagen formschlüssig mit dem Boden verbunden ist. Bei den bekannten Rahmen ist meistens am obern Ende des Rohrstückes ein Rand vorgesehen. Dieser ebenerdige Rand hat den Nachteil, dass der Rahmen auf dem umgebenden Boden aufliegt, so das er "schwimmend" ist. Dadurch ist keine zuverlässige Verbindung mit dem umliegenden Boden erreichbar.Regardless of the shape of the cross section of the frame, the problem arises of reliably installing the frame in the surrounding floor area in such a way that it is, so to speak, connected to the floor in a form-fitting manner. In the known frames, an edge is usually provided at the upper end of the pipe section. This ground-level edge has the disadvantage that the frame rests on the surrounding floor, so that it is "floating". As a result, no reliable connection to the surrounding soil can be achieved.

Hier setzt die Erfindung ein, der die Aufgabe zugrundeliegt, einen Rahmen der eingangs beschriebenen Art so weiter auszugestalten, dass das Rohrstück des Rahmens einfach im Boden verlegt und eine zuverlässige Verbindung mit dem umgebenden Bodenbereich erreicht wird.This is where the invention comes in, which is based on the object of further developing a frame of the type described at the outset in such a way that the tubular piece of the frame is simply laid in the ground and a reliable connection with the surrounding ground area is achieved.

Diese Aufgabe wird gemäss der Erfindung dadurch gelöst, dass an der Aussenfläche des Rohrstückes mindestens eine auswärts ragende Randpartie vorgesehen ist, die von dem obern Ende des Rohrstückes entfernt angeordnet ist. Dadurch, dass die Randpartie nicht am obern Rand des Rohrstückes angeordnet ist, wird erreicht, dass der Kragen in seiner Formgebung frei ausgebildet werden kann und zudem die zuverlässige Verbindung mit dem umgebenden Bodenbereich erreicht wird.This object is achieved according to the invention in that at least one outwardly projecting edge section is provided on the outer surface of the pipe section and is arranged at a distance from the upper end of the pipe section. The fact that the edge section is not arranged on the upper edge of the pipe section means that the shape of the collar can be freely formed and, moreover, the reliable connection to the surrounding floor area is achieved.

Der in Fig. 1 teilweise dargestellte Rahmen 1 ist ein Teil eines Rechteck- oder Kreis-Rahmens, welcher sich aus einem entsprechend geformten Rohrstück 2 und einem an der Aussenseite des Rohrstückes 2 angeordneten Kragen 3 zusammensetzt. An der im wesentlichen senkrecht verlaufenden Innenwand sind eine Anzahl Vorsprünge 4 (nur einer dargestellt) vorgesehen, auf denen ein Deckel oder ein Rost (nicht dargestellt) abgestützt werden kann. Hierzu weist der Vorsprung 4 auf seiner Oberseite eine Lagerfläche 5 auf, die in Fig. 1 horizontal verläuft. Die Lagerfläche 5 kann jedoch auch geneigt ausgebildet sein, wie dies in Fig. 2 gestrichelt dargestellt ist.The frame 1 partially shown in FIG. 1 is part of a rectangular or circular frame, which is composed of a correspondingly shaped pipe section 2 and a collar 3 arranged on the outside of the pipe section 2. There are a number on the essentially vertical inner wall Protrusions 4 (only one shown) are provided, on which a lid or a grate (not shown) can be supported. For this purpose, the projection 4 has on its upper side a bearing surface 5 which runs horizontally in FIG. 1. However, the bearing surface 5 can also be designed to be inclined, as shown in broken lines in FIG. 2.

Der an der Aussenseite des Rohrstückes 2 angeordnete Kragen 3 erstreckt sich im wesentlichen in horizontaler Richtung und liegt zwischen dem obern Rand 8 und dem untern Rand 9 des Rohrstückes 2. In Fig. 1 ist der Kragen 3 etwa ein Drittel der Höhe H des Rohrstückes 2 vom obern Rand 8 entfernt angeordnet. Zweckmässig ist es, die Distanz h des Kragens 3 vom obern Rand 8 etwa 0,2 - 0,8 H auszuführen. Ebenso kann die Breite W des Kragens 3 variieren, er beträgt jedoch zweckmässig nicht mehr als die Hälfte der Gesamthöhe H des Rohrstückes 2.The collar 3 arranged on the outside of the pipe section 2 extends essentially in the horizontal direction and lies between the upper edge 8 and the lower edge 9 of the pipe section 2. In FIG. 1, the collar 3 is approximately one third of the height H of the pipe section 2 arranged from the upper edge 8. It is expedient to carry out the distance h of the collar 3 from the upper edge 8 of approximately 0.2-0.8 H. The width W of the collar 3 can likewise vary, but it is expediently not more than half the total height H of the pipe section 2.

In Fig. 2 ist der Einbau des Rahmens 1 in einem künstlich angelegten Boden 10, beispielsweise in einer Fahrbahn dargestellt. Die vom Rahmen 1 umrandete Oeffnung 11, beispielsweise eines Schachtes, ist entweder von einer Betonschicht 12 oder von einer Lage von Blöcken 15 umgeben. Zur Abdichtung des Schachtes zu der den Rahmen 1 umgebenden Schicht ist an der Aussenseite des Rohrstückes 2 eine Umfangsrille 16 eingearbeitet, in welche ein Weichdichtungsring 17, beispielsweise ein O-Ring, eingelegt ist. Der Weichdichtungsring 17 hat die Aufgabe, das Eindringen von Feuchtigkeit aus dem Schacht mit der Oeffnung 11 zu verhindern.2 shows the installation of the frame 1 in an artificially created floor 10, for example in a roadway. The opening 11 surrounded by the frame 1, for example a shaft, is either surrounded by a concrete layer 12 or by a layer of blocks 15. To seal the shaft to the layer surrounding the frame 1, a circumferential groove 16 is incorporated on the outside of the pipe section 2, into which a soft sealing ring 17, for example an O-ring, is inserted. The soft sealing ring 17 has the task of preventing the ingress of moisture from the shaft with the opening 11.

Wird der Rahmen 1 in den Boden 10 eingesetzt, der beispielsweise eine Schicht aus Asphalt, Beton oder aus einem andern Material bestehen kann, kann diese Schicht sich oberhalb und unterhalb des Kragens 3 erstrecken, wodurch der Rahmen sicher gehalten wird. Dadurch dass der Kragen 3 unterhalb des oberen Randes 8 liegt, ist die Installation, das Entfernen und Anpassen des Rahmens verhältnismässig einfach. Da der Kragen 3 vollständing und allseits vom Bodenmaterial umgeben ist, wird der Rahmen 1 stabil im Boden gehalten, so dass die Gefahr, dass er durch Verkehrsbelastungen beeinträchtigt wird, sehr gering ist.If the frame 1 is inserted into the floor 10, which can consist, for example, of a layer of asphalt, concrete or another material, this layer can extend above and below the collar 3, as a result of which the frame is held securely. The fact that the collar 3 lies below the upper edge 8 is the installation, removal and adjustment of the frame relatively easy. Since the collar 3 is completely and surrounded on all sides by the floor material, the frame 1 is held stable in the floor, so that the risk of it being impaired by traffic loads is very low.

In Fig. 3 weist der Rahmen 1 eine von der Form nach Fig. 1 und 2 abweichende Form auf. Der obere Rand 8 ist gegenüber dem unteren Rand 9 zurückgesetzt und geht in eine geneigte Lagerfläche 19 über, auf welcher ein Rost oder ein Deckel 18 abgestützt werden kann, eine entsprechend geneigte Auflagefläche 20 wie die Lagerfläche 19 aufweisen kann. Der an der Aussenseite angeordnete Kragen 3 liegt ungefähr ein Drittel der Gesamthöhe des Rohrstückes unter dem obern Rand 8. Auch in diesem Fall ist eine Rille 16 zur Aufnahme eines Weichdichtungsringes 17 vorgesehen. Auch bei dieser Ausführungsform des Rahmens ist der Kragen 3 allseits vom Bodenmaterial umgeben.In Fig. 3, the frame 1 has a shape different from the shape of Figs. 1 and 2. The upper edge 8 is set back from the lower edge 9 and merges into an inclined bearing surface 19, on which a grate or a cover 18 can be supported, and can have a correspondingly inclined bearing surface 20 as the bearing surface 19. The collar 3 arranged on the outside lies approximately one third of the total height of the pipe section below the upper edge 8. In this case too, a groove 16 is provided for receiving a soft sealing ring 17. In this embodiment of the frame, the collar 3 is surrounded on all sides by the base material.

Der in Fig. 4 dargestellte weitere Rahmen 1 weist eine abwärts und einwärts geneigte Lagerfläche 19 auf, die sich die Auflagefläche eines nicht dargestellten Deckels abstützt. Da das Rohrstück 2 auf der Aussenseite als gerader Zylinder 21 ausgebildet ist, weist der untere Teil der Innenwand des Rohrstückes 2 eine abwärts und auswärts geneigte Form auf. Der Kragen 3 ist im vorliegenden Fall ungefähr in der Mitte der Höhe des Rohrstückes 2 angeordnet. Der Rahmen 1 ist mit seinem unteren Teil in ein Mauerwerk eingepasst, während der Kragen 3 sich im Material der Fahrbahn befindet, das unterhalb und oberhalb des Kragens 3 aufgefüllt wird. Auch in diesem Fall wird der Rahmen zuverlässig im Material der Fahrbahn gehalten, so dass er auch bei grossem Verkehrsfluss nicht leicht verschoben werden kann. Muss jedoch der Rahmen 1 für Unterhaltszwecke entfernt werden, ist dies möglich, ohne dass an der Fahrbahn grosse Veränderungen vorgenommen werden müssen.The further frame 1 shown in FIG. 4 has a bearing surface 19 which is inclined downwards and inwards and which supports the bearing surface of a cover, not shown. Since the pipe section 2 is formed on the outside as a straight cylinder 21, the lower part of the inner wall of the pipe section 2 has a downward and outward inclined shape. The collar 3 is arranged approximately in the middle of the height of the pipe section 2 in the present case. The lower part of the frame 1 is fitted into masonry, while the collar 3 is in the material of the roadway, which is filled in below and above the collar 3. In this case too, the frame is held reliably in the material of the roadway, so that it cannot be moved easily even when there is a large flow of traffic. However, if the frame 1 has to be removed for maintenance purposes, this is possible without major changes to the roadway.

In dem in Fig. 5 schematisch dargestellten Rahmen ist das Rohrstück 2 ein im wesentlichen rechteckiger, hohler Kasten, der den nach aussen ragenden Kragen 3 aufweist. Der Kragen 3 ist ungefähr ein Drittel der Gesamthöhe unterhalb dem obern Rand 8 angeordnet und weist eine Anzahl Durchgänge 25 auf.In the frame shown schematically in Fig. 5, the pipe section 2 is a substantially rectangular, hollow box, which has the collar 3 projecting outwards. The collar 3 is arranged approximately one third of the total height below the upper edge 8 and has a number of passages 25.

Wie aus Fig. 6 ersichtlich ist, die einen Schnitt durch die Wand 2 des Rahmens 1 nach Fig. 5 zeigt, ist der Kragen 3 mit einem abwärts gerichteten nach aussen konvexen Profil versehen, durch welches die Verankerung im Bodenmaterial verbessert wird. Durch die Durchgänge 25 kann Asphalt oder Schotter oder flüssiger Beton und anderes Strassenmaterial eingebracht werden. Das konvex abgerundete Profil des Kragens 3 stellt einen Vorteil sowohl bei der Erstinstallation als auch bei der Befestigung des Rahmens 1 bezüglich der Verkehrsbelastungen dar.As can be seen from FIG. 6, which shows a section through the wall 2 of the frame 1 according to FIG. 5, the collar 3 is provided with a downwardly outwardly convex profile, by means of which the anchoring in the floor material is improved. Asphalt or gravel or liquid concrete and other road material can be introduced through the passages 25. The convexly rounded profile of the collar 3 represents an advantage both in the initial installation and in the fastening of the frame 1 with regard to the traffic loads.

In den Figuren 7, 8 und 9 sind Varianten für die Ausbildung des Kragens 3 dargestellt, der auf der Aussenseite des Rohrstückes 2 anstelle des in Fig. 5 dargestellten Kragens angeordnet ist. In Fig. 7 ist der vorstehende Kragen im wesentlichen horizontal angeordnet und weist nur am äussersten Teil seines freien Endes eine nach unten ragende Partie 26 auf.FIGS. 7, 8 and 9 show variants for the design of the collar 3, which is arranged on the outside of the pipe section 2 instead of the collar shown in FIG. 5. In Fig. 7 the projecting collar is arranged essentially horizontally and has a portion 26 projecting downward only at the outermost part of its free end.

In Fig. 8 weist der Kragen 3 ein gerades Profil auf, das jedoch dachförmig schräg nach abwärts gerichtet ist.8, the collar 3 has a straight profile, which, however, is directed obliquely downwards in a roof shape.

Der Kragen 3 nach Fig. 9 erstreckt sich im wesentlichen horizontal, wobei eine Partie 27 des Kragens 3 vertikal nach unten gerichtet ist.The collar 3 according to FIG. 9 extends essentially horizontally, a part 27 of the collar 3 being directed vertically downwards.

In Fig. 10 ist ein Rahmen 1 mit einem rechteckförmigen Rohrstück 2 dargestellt. Der Kragen 3 ist hier in Einzelpartien aufgelöst und weist griffartige Lappen 30 auf, die im wesentlichen dasselbe Profil aufweisen wie der Kragen 3 in Fig. 6. Die griffartigen Lappen 30 können entweder zusammen mit dem Rohrstück 2 gegossen oder getrennt hergestellt und an die Aussenseite des Rohrstückes 2 angeschweisst, angeschraubt oder angenietet werden.10 shows a frame 1 with a rectangular tube section 2. The collar 3 is here broken up into individual parts and has handle-like tabs 30, which have essentially the same profile as the collar 3 in FIG. 6. The handle-like tabs 30 can either be cast together with the pipe section 2 or manufactured separately and welded, screwed or riveted to the outside of the pipe section 2.

Der in Fig. 11 dargestellte Rahmen 1 weist ebenfalls ein rechteck- oder quaderförmiges Rohrstück 2 auf, wobei ähnlich wie in Fig. 10 der Kragen 3 in einzelne, mit Abstand voneinander angeordnete Lappen 30 unterteilt ist. Bei der Ausführung nach Fig. 11 ist der Lappen 30 horizontal nach aussen gerichtet, die auf der Höhe h unterhalb des oberen Randes 8 des Rahmens 1 angeordnet sind. Auf der Unterseite der Lappen 30 sind nach abwärts und einwärts geneigte Flanken 31 befestigt, welche kegel- oder pyramidenförmig zu einer Spitze 32 auslaufen. Dadurch wird erreicht, dass das Rohrstück 2 leicht nach unten in das Bodenmaterial eingepresst werden kann, während der im wesentlichen horizontale Lappen 30 eine wirksame Verankerung des Rahmens 1 im Bodenmaterial liefert, wenn das Strassenmaterial aufgefüllt ist. Die kegel- oder pyramidenförmig ausgebildeten Flanken 31 können entweder aus einem Stück gefertigt oder aus mehreren Stücken zusammengesetzt sein. Beide Ausführungen sind in Fig. 11 dargestellt.The frame 1 shown in FIG. 11 also has a rectangular or cuboid tubular piece 2, with the collar 3 being divided into individual tabs 30 spaced apart from one another, as in FIG. 10. 11, the tab 30 is directed horizontally outwards, which are arranged at the height h below the upper edge 8 of the frame 1. On the underside of the tabs 30, downwardly and inwardly inclined flanks 31 are fastened, which end in a cone or pyramid shape to a tip 32. It is thereby achieved that the pipe section 2 can be easily pressed down into the floor material, while the substantially horizontal tab 30 provides an effective anchoring of the frame 1 in the floor material when the road material is filled.
