Abstract
Description
Verstellbare Schachtabdeckung Adjustable manhole cover
Die Erfindung betrifft eine verstellbare Schachtabdeckung, wie vielfach im Strassenbau verwendet. Solche Schachtab -deckungen sollten mit der Strassenoberfläche möglichst bündig liegen und extreme Belastungen aufnehmen können, wie sie beim Überfahren durch Schwerfahrzeuge auftreten.The invention relates to an adjustable manhole cover, as is often the case used in road construction. Such manhole covers should be flush with the road surface lie as flush as possible and can withstand extreme loads such as those caused by driving over them occur through heavy vehicles.
Bei Reparaturen der Strassendecke oder einer Neubeschichtung der Bitumenauflage ist es notwendig die Schachtabdeckung auf die projektierte, veränderte Belagshöhe anzupassen. Dies erfordert ein umfangreiches Aufbrechen der Strassendecke, Herauslösen und erneutes Versetzen der Basisrahmen der Schachtabdeckungen, mit grossem Geld - und Zeitaufwand.For repairs to the road surface or a new coating of the bitumen layer it is necessary to adjust the shaft cover to the projected, changed covering height adapt. This requires extensive breaking up of the road surface, detachment and relocating the base frame of the manhole covers again, with a lot of money - and expenditure of time.
Der Erfindung liegt die Aufgabe zugrunde jegliche Änderungen des Niveaus solcher Schachtabdeckungen mit einem Mininrum an Arbeitsaufwand zu ermöglichen. Zudem sollten die Teile der Schachtabdeckung gusstechnisch leicht herzustellen sein.The invention is based on any changes in the level to enable such manhole covers with a minimum of work. In addition, the parts of the manhole cover should be easy to manufacture by casting.
Diese Aufgabe wird erfindungsgemäss dadurch gelöst, dass der Basisrahmen sich aus einem äusseren festbetonierten Rahmen und aus einem zweiten beweglichen inneren Rahmen zusammensetzt, wobei der innere Rahmen an seiner Aussenseite einen zahnradartigen Kranz von vertikal verlaufenden Er -hebungen aufweist welche von entsprechenden vertikalen Ver -tiefungen an der Innenseite des äusseren Ringes aufgenommen werden. Diese Verzahnung ist in ihrer unteren wie oberen Be -grenzung von Zahn zu Zahn. gestaffelt um den gleichen ert vertikal versetzt dergestalit, dass ein Herausheben des inneren Rahmens und das um eine Zahnbreite in Ansteigrichtung versetzte Einsetzen des Rahmens diesen in seinem Niveau an -hebt.According to the invention, this object is achieved in that the base frame consists of an outer concrete frame and a second movable one composed of inner frame, the inner frame on its outside a Gear-like ring of vertically extending elevations has which of corresponding vertical recesses on the inside of the outer ring will. This toothing is in its upper and lower boundaries from tooth to Tooth. staggered around the same vertically offset in such a way that it can be lifted out of the inner frame and the insertion offset by one tooth width in the direction of increase of the frame raises it in its level.
Um bei jeder Versetzungshöhe ringsum eine gleichmaßige verteilte Auflage zu bieten ist die Verzahnung im wieder -holungsfeld um jeweils eine Zahnbreite versetzt(Fig.3,4 & 5), so dass in Verzahnungsfeld I ( 4 a & b ) die Unterseite der Verzahnung, in Feld II ( 5 a & b ) die Oberseite der Ver -zahnung die Auflagefläche bildet.In order to have an evenly distributed support all around at every offset height the toothing in the repetition field is offset by one tooth width each (Fig. 3,4 & 5), so that in toothing field I (4 a & b) the underside of the toothing, in field II (5 a & b) the top of the toothing forms the support surface.
Für eine Höhenverstellung des ochachtabdeckung ist es nur mehr nötig eine relativ dünne Bitumenschicht um den inneren Rahmen zu lösen, soweit, dass dieser herSusgehoben werden kann.It is only necessary to adjust the height of the shaft cover a relatively thin layer of bitumen to loosen the inner frame, so that this can be lifted out.
Die beigefügte Zeichnung zeigt mit Figur 1 den aufbau der erfindungsgemässen Schachtabdeckung bestehend aus Schacht -deckel (1), innerem Rahmen (2) und äus,erem Rahmen (3).The attached drawing shows with Figure 1 the structure of the invention Manhole cover consisting of manhole cover (1), inner frame (2) and outer Frame (3).
Figur 2 zeigt in Draufsicht eine mögliche Form der Verzahn -ung der beiden ilahmen- In Figur 3 und 4 sind die in Ab -wicklung dargestellte Verzahnung der beiden Rahmen (2 & 3) zu sehen, mit dem jeweiligen Querschnitt rechts.FIG. 2 shows a possible form of the toothing in a plan view In Figure 3 and 4 are the teeth shown in the development of the two frames (2 & 3) can be seen with the respective cross-section on the right.
Die Funktionsweise der Verzahnung in angehobener Stellung ist aus Figur 5 ersichtlich. Figur 6 zeigt eine Variation mit nur einer kontinuierlichen Verzahnung auf 360°.The function of the toothing in the raised position is off Figure 5 can be seen. Figure 6 shows a variation with only one continuous Toothing at 360 °.
Figur 9, 10, 11, 12 & 13 zeigen mehrere normen der Ver -zahnungFigures 9, 10, 11, 12 & 13 show several standards for gearing
