Abstract

1. A polygonal, particularly rectangular, frame for man-hole covers assembled from a number of frame members (1, 2, 3, 4) extending lengthwise of the frame sides, the frame members being provided with supporting and/or inclined sealing faces for a cover, at least two opposed frame members (1, 3) being identical, characterized in that one pair of opposed frame members (1, 3) is interchangeable after turning it by 180 degrees about an axis (X) extending parallel with the frame plane, and in that the other pair of opposed frame members (2, 4) is interchangeable after turning it by 180 degrees about an axis (Y) parallel with the frame plane and rotating it about an axis (Z) normal to the frame plane.

Description

Die Erfindung betrifft einen mehreckigen, insbesondere rechteckigen Rahmen für Schachtabdeckungen, der aus mehreren längs der Rahmenseite verlaufenden Rahmenteilen zusammengesetzt ist, an denen Auflage- und/oder geneigte Dichtflächen für einen Deckel ausgebildet sind, wobei wenigstens zwei sich gegenüberliegende Rahmenteile identisch ausgebildet sind.The invention relates to a polygonal, in particular rectangular frame for manhole covers, which is composed of a plurality of frame parts running along the frame side, on which support and / or inclined sealing surfaces for a cover are formed, at least two frame parts lying opposite one another being of identical design.

Ein solcher Rahmen ist beispielsweise in der US-A-1820127 beschrieben. Die längsseitigen Rahmenteile sind jedoch nicht gegeneinander austauschbar wegen am einen Ende derselben angeformter Schrägführungen für den Deckel. Nur die Rahmenteile an den Schmalseiten können durch Drehen um eine zur Rahmenebene senkrechte Achse gegeneinander ausgetauscht werden, da sie identisch ausgebildet sind. Das gleiche trifft zu auf den Rahmen nach der US-A-2 194 221.Such a frame is described, for example, in US-A-1820127. However, the longitudinal frame parts are not interchangeable because of inclined guides for the cover formed on one end of the same. Only the frame parts on the narrow sides can be exchanged for each other by rotating about an axis perpendicular to the frame plane, since they are identical. The same applies to the frame according to US-A-2 194 221.

Die Rahmenteile dieser bekannten Rahmen für Schachtabdeckungen können durch Wenden und Drehen nicht so gegeneinander ausgetauscht werden, daß zwei verschiedene Deckelformen bei gleichen Rahmenteilen verwendet werden können. Da zwei von den sich gegenüberliegenden Rahmenteilen unterschiedlich geneigte Dichtflächen aufweisen, ist bei den bekannten Rahmen dieses Paar der Rahmenteile verschieden ausgebildet. Es müssen daher pro Rahmen drei verschiedene Rahmenteile gefertigt und auf Lager gehalten werden. Bei einem kompletten Programm von nach lichter Weite gestaffelten und nach Belastbarkeit klassifizierten Abdeckungen erfordert dies eine Vielzahl von Gußmodellen und eine sehr umfangreiche Lagerhaltung. Diese vermehrt sich noch, wenn Rahmen für Deckel mit unterschiedlicher Einlegetiefe und/oder Neigung der Seitenflächen vorgesehen werden sollen.The frame parts of these known frames for manhole covers cannot be interchanged by turning and turning so that two different cover shapes can be used with the same frame parts. Since two of the opposite frame parts have differently inclined sealing surfaces, this pair of frame parts is designed differently in the known frames. Therefore, three different frame parts must be manufactured per frame and kept in stock. With a complete range of covers that are staggered by light width and classified according to load capacity, this requires a large number of cast models and a very extensive inventory. This increases when frames for lids with different insertion depths and / or inclinations of the side surfaces are to be provided.

Der Erfindung liegt die Aufgabe zugrunde, bei Rahmen für Schachtabdeckungen der eingangs genannten Art die Rahmenteile so zu gestalten, daß mit den gleichen Rahmenteilen Rahmen zusammengesetzt werden können, die Deckel mit zwei verschiedenen Einlegetiefen aufnehmen können.The invention has for its object to design the frame parts for frames for manhole covers of the type mentioned so that frames can be assembled with the same frame parts that can accommodate lids with two different insertion depths.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß das eine sich gegenüberliegende Paar von Rahmenteilen nach Wenden um 180° um eine zur Rahmenebene parallele Achse (X) miteinander austauschbar ist und daß das andere sich gegenüberliegende Paar von Rahmenteilen nach Wenden um 180° um eine zur Rahmenebene parallele Achse (Y) und Drehen um eine zur Rahmenebene senkrechte Achse (Z) miteinander austauschbar ist.This object is achieved in that the opposite pair of frame parts after turning through 180 ° about an axis parallel to the frame plane (X) is interchangeable and that the other opposite pair of frame parts after turning through 180 ° around the frame plane parallel axis (Y) and rotation about an axis perpendicular to the frame plane (Z) is interchangeable.

Dadurch wird zunächst der Vorteil erzielt, daß ein und dasselbe Rahmenteil auch auf der gegenüberliegenden Rahmenseite eingebaut werden kann. Man kann also z. B. zwei einander gegenüberliegende Rahmenteile identisch ausbilden, so daß man gegenüber der bisher bekannten Konstruktion mit zwei unterschiedlichen Rahmenteilen auskommt, wodurch sich Herstellung und Lagerhaltung entsprechend vereinfachen. Trotz identischer Ausbildung der Rahmenteile des einen Paares wird durch die Maßnahme, daß das eine Rahmenteil um 180° gewendet gegenüber dem gegenüberliegenden Rahmenteil eingebaut wird, die gewünschte unterschiedliche Orientierung der Neigung der Dichtflächen erzielt. Es wird ferner erreicht, daß die einander gegenüberliegenden Rahmenteile des anderen Paares nach dem Wenden um die zur Rahmenebene parallele Achse und nach Drehen um die zur Rahmenebene senkrechte Achse einen Deckel mit anderen Einlegetiefe und/oder Neigung der Seitenflächen aufnehmen. Durch anderen Zusammenbau läßt sich somit der Rahmen an eine andere Deckelform anpassen.This initially has the advantage that one and the same frame part can also be installed on the opposite side of the frame. So you can z. B. form two opposing frame parts identically, so that one can make do with the previously known construction with two different frame parts, which simplifies manufacture and storage accordingly. Despite the identical design of the frame parts of the one pair, the measure that the one frame part is turned through 180 ° relative to the opposite frame part achieves the desired different orientation of the inclination of the sealing surfaces. It is also achieved that the opposing frame parts of the other pair after turning about the axis parallel to the frame plane and after rotating about the axis perpendicular to the frame plane receive a cover with a different insertion depth and / or inclination of the side surfaces. The frame can be adapted to a different cover shape by a different assembly.

Der in Fig. 1-4 dargestellte Rahmen ist rechteckig und aus vier Rahmenteilen 1, 2, 3,4 zusammengesetzt, die an den Ecken miteinander verschraubt sind. Diese Rahmenteile weisen an der Rahmeninnenseite glatte Dichtflächen 11, 12, 13, 14 auf. Diese Dichtflächen sind gegenüber der Rahmenebene (X-Y-Ebene in Fig.4) schräg geneigt, und zwar haben die Dichtflächen 11, 12 und 14 eine nach außen bzw. oben gerichtete Neigung, während die Dichtfläche 13 nach innen bzw. unten geneigt, also unterschnitten ist. Die Dichtflächen 11 und 13 verlaufen parallel zueinander, die Dichtflächen 12 und 14 divergieren nach oben. Diese Dichtflächen wirken mit den in gleicher Weise geneigten seitlichen Stoßflächen eines (nicht dargestellten) Deckels zusammen, der in den Rahmen eingelegt werden kann, wobei er die Dichtfläche 13 untergreift. Die Rahmenteile 2 und 4 haben außerdem nach innen vorspringende Flansche zur Bildung je einer parallel zur Rahmenebene verlaufenden Auflagefläche 22, 24, auf der der Deckel aufsitzen kann.The frame shown in Fig. 1-4 is rectangular and composed of four frame parts 1, 2, 3.4, which are screwed together at the corners. These frame parts have smooth sealing surfaces 11, 12, 13, 14 on the inside of the frame. These sealing surfaces are inclined relative to the frame plane (XY plane in FIG. 4), specifically the sealing surfaces 11, 12 and 14 have an outward or upward inclination, while the sealing surface 13 is inclined inward or downward, that is to say undercut is. The sealing surfaces 11 and 13 run parallel to one another, the sealing surfaces 12 and 14 diverge upwards. These sealing surfaces interact with the equally inclined lateral abutting surfaces of a cover (not shown) which can be inserted into the frame, engaging under the sealing surface 13. The frame parts 2 and 4 also have inwardly projecting flanges to form a respective support surface 22, 24 which runs parallel to the frame plane and on which the cover can rest.

Beim Herstellen der Schachtabdeckung werden die mit geringem Untermaß gefertigten Rahmenteile 1, 2, 3, 4 zuerst lose miteinander verschraubt, dann der Deckel auf die Auflageflächen 22, 24 aufgelegt und dann die Verschraubung der Rahmenteile festgezogen, bis die Dichtflächen 1, 12, 13, 14 satt abdichtend gegen die seitlichen Stoßflächen des Deckels anliegen.When manufacturing the manhole cover, the frame parts 1, 2, 3, 4 manufactured with a small undersize are first loosely screwed together, then the cover is placed on the bearing surfaces 22, 24 and then the screw connection of the frame parts is tightened until the sealing surfaces 1, 12, 13, 14 fit tightly against the side abutting surfaces of the cover.

In die Stoßfugen zwischen den Rahmenteilen an den Rahmenecken kann eine Dichtungsmasse eingefügt werden, die dann erstarrt.A sealing compound, which then solidifies, can be inserted into the butt joints between the frame parts at the frame corners.

Die einander gegenüberliegenden Rahmenteile 1 und 3 haben eine identische Form, und ebenso die Rahmenteile 2 und 4. Das Rahmenteil 3 ist gegenüber dem Rahmenteil 1 um 180° bezüglich einer Achse gedreht, die parallel zur Rahmenebene und parallel zur Längsmittellinie des Rahmenteils 1 bzw. 3 verläuft, d. h. um eine zur in Fig. 4 angegebenen X-Achse parallele Achse. Dadurch gelangen die Dichtflächen 11, 13 in die gewünschte parallele Anordnung. Diese Rahmenteile 1 und 3 haben keine Auflageflächen für den Deckel.The opposite frames parts 1 and 3 have an identical shape, and also the frame parts 2 and 4. The frame part 3 is rotated relative to the frame part 1 by 180 ° with respect to an axis which runs parallel to the frame plane and parallel to the longitudinal center line of the frame part 1 or 3, ie about an axis parallel to the X axis indicated in FIG. 4. As a result, the sealing surfaces 11, 13 reach the desired parallel arrangement. These frame parts 1 and 3 have no support surfaces for the lid.

Das Rahmenteil 2 hat nicht nur einen nach innen vorspringenden Flansch, der die Auflagefläche 22 bildet, sondern auch einen nach außen vorspringenden Flansch, der eine weitere Auflagefläche 22' bildet. Entsprechendes gilt für das identisch ausgebildete Rahmenteil 4. Das Rahmenteil 4 ist gegenüber dem Rahmenteil 2 um 180° bezüglich einer Achse gedreht, die parallel zur Rahmenebene und senkrecht zur Längsmittellinie des Rahmenteils 2 bzw. 4 verläuft, also um eine zur angegebenen X-Achse parallele Achse.The frame part 2 has not only an inwardly projecting flange which forms the support surface 22, but also an outwardly projecting flange which forms a further support surface 22 '. The same applies to the identically designed frame part 4. The frame part 4 is rotated relative to the frame part 2 by 180 ° with respect to an axis which runs parallel to the frame plane and perpendicular to the longitudinal center line of the frame part 2 or 4, that is to say about a parallel to the specified X axis Axis.

Zum Zwecke der Eckverschraubung sind lediglich die Rahmenteile 2 und 4 mit rechtwinklig abstehenden Flanschen 8, 9 versehen, die ebenfalls zur Rahmenebene (X-Y-Ebene) schräg geneigt sind, so daß sie sich an die geneigten Rahmenteile 1, 3 anlegen. Die Flansche 8, 9 gehen nicht über die ganze Höhe der Rahmenteile 2, 4 durch, sondern lassen den für die Auflage des Deckels benötigten Raum oberhalb der Auflageflächen 22, 24 bzw. unterhalb der Auflageflächen 22', 24' frei. Dasselbe gilt von etwaigen Versteifungsrippen 16, 17 der Rahmenteile 2 bzw. 4, die ebenfalls auf beiden Seiten, aber nicht über die ganze Höhe durchgehend angeordnet sind.For the purpose of corner screwing, only the frame parts 2 and 4 are provided with flanges 8, 9 projecting at right angles, which are also inclined to the frame plane (X-Y plane), so that they abut the inclined frame parts 1, 3. The flanges 8, 9 do not extend over the entire height of the frame parts 2, 4, but rather leave the space required for supporting the cover above the support surfaces 22, 24 or below the support surfaces 22 ', 24'. The same applies to any stiffening ribs 16, 17 of the frame parts 2 and 4, which are also arranged on both sides, but not continuously over the entire height.

Dagegen haben die Rahmenteile 1, 3 Versteifungsrippen 18, 19 nur auf einer Seite, wobei die senkrecht verlaufenden Rippen 19 über die ganze Höhe durchgehen können. An den Ecken haben die Rahmenteile 1 und 3 keine Flansche. Zur Herstellung der Rahmenteile 1, 3 brauchen daher nur entsprechende Stücke von einem längeren Profilstreifen abgeschnitten und mit Bohrungen zur Aufnahme der Schrauben für die Eckverschraubung versehen werden.In contrast, the frame parts 1, 3 have stiffening ribs 18, 19 only on one side, the perpendicular ribs 19 being able to pass over the entire height. At the corners, frame parts 1 and 3 have no flanges. To produce the frame parts 1, 3, therefore, only corresponding pieces need to be cut off from a longer profile strip and provided with bores for receiving the screws for the corner screw connection.

Änderungen der dargestellten Ausführungsform sind im Rahmen der Erfindung möglich. So brauchen die einzelnen Rahmenteile nicht über die ganze Seitenlänge des Rahmens durchzugehen, sondern es können auch mehrere kürzere Rahmenteile aneinandergesetzt werden. Ferner ist es möglich, auch an den beiden Rahmenteilen 1 und 3 einen nach innen vorspringenden Flansch zur Bildung einer Auflagefläche für den Deckel vorzusehen. Dieser Flansch muß natürlich kürzer sein als die Länge der Rahmenteile 1, 3 und außerdem setzt eine solche Ausführungsform voraus, daß die Einlegetiefe des Deckels kleiner als die halbe Rahmenhöhe ist, damit ein mittiger Flansch auf beiden Seite eine Auflagefläche bilden kann.Changes to the illustrated embodiment are possible within the scope of the invention. Thus, the individual frame parts do not have to go through the entire side length of the frame, but several shorter frame parts can also be put together. Furthermore, it is also possible to provide an inwardly projecting flange on the two frame parts 1 and 3 to form a support surface for the cover. This flange must of course be shorter than the length of the frame parts 1, 3 and also such an embodiment requires that the insertion depth of the cover is less than half the frame height, so that a central flange can form a bearing surface on both sides.

Die Ausführungsform nach Fig. 5 unterscheidet sich von der nach Fig. 4 lediglich dadurch, daß die Auflageflächen 22, 24 tiefer gelegt sind, so daß der Abstand der Auflageflächen 22, 24 von der Oberkante der Rahmenteile 2, 4 größer ist als der Abstand der (in dieser Einbaustellung nicht benötigten) Auflageflächen 22', 24' von er Unterkante der Rahmenteile 2,4. Die Rahmenteile 2, 4 sind daher zueinander zwar spiegelsymmetrisch bezüglich der Achse Y, aber nicht mehr identisch. Werden die Rahmenteile 2,4 um 180° bezüglich der Achse X gedreht und dann miteinander vertauscht, dann kommen die Auflageflächen 22', 24' in die Betriebslage an der Rahmeninnenseite, und können dann als Auflageflächen für einen Deckel mit geringerer Einlegetiefe dienen.The embodiment of FIG. 5 differs from that of FIG. 4 only in that the support surfaces 22, 24 are placed lower, so that the distance of the support surfaces 22, 24 from the upper edge of the frame parts 2, 4 is greater than the distance of the (In this installation position not required) support surfaces 22 ', 24' from the lower edge of the frame parts 2,4. The frame parts 2, 4 are therefore mirror-symmetrical to one another with respect to the axis Y, but are no longer identical. If the frame parts 2, 4 are rotated by 180 ° with respect to the axis X and then exchanged with one another, then the support surfaces 22 ', 24' come into the operating position on the inside of the frame and can then serve as support surfaces for a cover with a lower insertion depth.
