Beschreibung description
Die Erfindung betrifft einen Schachtdeckel zum provisorischen Abdecken eines Strassenschachtes. Er kann z.B. verwendet werden: The invention relates to a manhole cover for the provisional covering of a street shaft. He can e.g. be used:
a. als provisorische Abdeckung während der Bauphase; a. as a temporary cover during the construction phase;
b. als provisorischer Hilfsdeckel während des Schwarzbelagseinbaues, wenn der Originaldeckel kein ovales Pickelloch aufweist oder der verlangten Negativbelastung (Zug nach oben) nicht standhalten kann; b. as a temporary auxiliary cover when installing the black coating if the original cover does not have an oval pimple hole or cannot withstand the required negative load (upward pull);
c. als tieferliegender Hilfsdeckel bei Belagsabfrä-sungen, um genügend Frästiefe zu erreichen. c. as a lower-lying auxiliary cover when milling the base in order to achieve sufficient milling depth.
Im Vergleich mit einem gleich stark belastbaren Normalgussdeckel soll er in Leichtbauweise durch die besondere Formgebung eine ebenbürtige Tragfähigkeit von oben und von unten besitzen. Zur Lösung dieser Aufgabe weist der Schachtdeckel die Merkmale gemäss Anspruch 1 auf. Durch Verwendung besserer Gussqualitäten kann der Deckel speziell im Zwischenbereich und Randbereich leichter dimensioniert werden. In comparison to a normal cast lid with the same load capacity, its lightweight design means that it has an equal load-bearing capacity from above and below due to its special shape. To achieve this object, the manhole cover has the features according to claim 1. By using better casting qualities, the lid can be dimensioned more easily, especially in the intermediate area and edge area.
Diese Leichtbauweise darf dem normalen Strassenverkehr nicht ohne Zusatzbaiast ausgesetzt werden, da ein leichter Deckel bei der schnellen Überfahrung herausspringen könnte. Die im Zwischenbereich vorhandenen Segmentaussparungen machen jeden Laien darauf aufmerksam, dass diese Abdek-kung entweder umfahren werden muss (durch Absperrung signalisiert) oder aber mit einem Füllstoff wie Schwarzbelag oder Beton bis auf die bestehende Fahrbahnfläche aufgefüllt werden muss. This lightweight construction must not be exposed to normal road traffic without an additional bast, since a light cover could pop out during the quick passage. The segment recesses in the intermediate area make every layperson aware that this cover either has to be bypassed (signaled by a barrier) or that it has to be filled up with a filler such as black coating or concrete to the existing road surface.
Ein Ausführungsbeispiel des Schachtdeckels wird nachfolgend anhand der Zeichnungen näher erläutert. An embodiment of the manhole cover is explained in more detail below with reference to the drawings.
Es zeigen: Show it:
Fig. 1 einen Axialschnitt durch den Schachtdek-kel gemäss der Linie A-A in Fig. 2. 1 shows an axial section through the manhole cover according to line A-A in FIG. 2.
Fig. 2 eine Draufsicht auf einen Viertel des Dek-kels Fig. 2 is a plan view of a quarter of the lid
Fig. 3 eine Ansicht von unten Fig. 3 is a bottom view
Fig. 4 einen Teilquerschnitt gemäss der Linie B-B in Fig. 2. 4 shows a partial cross section along the line B-B in FIG. 2.
Der gegossene Schachtdeckel weist einen Zentrumsbereich 1 auf, in welchem der Schachtdeckel die grösste Wandstärke besitzt, welche gegen den Mittelbereich abnimmt. Ferner einen Randbereich 2 mit etwa 1/5 der Wandstärke des Zentrumsbereiches und dazwischen einen Mittelbereich 3 mit oben und unten so tiefen abwechselnden Aussparungen, womit eine noch geringere Wandstärke besteht als im Aussenwandbereich. The cast manhole cover has a center area 1, in which the manhole cover has the greatest wall thickness, which decreases towards the central area. Furthermore, an edge area 2 with about 1/5 of the wall thickness of the center area and in between a middle area 3 with alternating recesses so deep at the top and bottom, whereby there is an even smaller wall thickness than in the outer wall area.
Dieser Mittelbereich ist oben und unten segmentflächig bündig mit dem Zentrumsbereich. This middle area is flush with the center area at the top and bottom of the segment.
Der Zentrumsbereich weist in der Mitte ein den Deckel durchsetzendes, ovales Pickelloch auf, um den Deckel mittels eines Hebegeätes vom Schacht abheben zu können, das von unten mit einer Einzellast angreift, welche grösser ist als die von oben wirkende Verkehrslast. The center area has an oval pick hole through the lid in order to be able to lift the lid off the shaft by means of a lifting device, which acts from below with a single load that is greater than the traffic load acting from above.
