KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Den Gegenstand der Erfindung bildet ein j in der Höhenlage verstellbarer Schachtdeckel j mit Unterlagsrahmen für Schächte jeglicher Art, wie sie im städtischen Tiefbau vielfach Verwendung finden.The subject of the invention is a manhole cover j adjustable in height with support frames for manholes of any kind, as is often the case in urban civil engineering Find use.
Das Neue an der Erfindung ist, daß der Deckel samt dem Rahmen, auf dem er ruht, auf einfache Weise in der Höhenlage verändert werden kann. Durch diese Erfindung ίο wird dem Übelstand entgegengetreten, daß die Schachtdeckel, wenn das sie umgebende Pflaster im Laufe der Zeit sackt oder wenn bei einer mit Schotter befestigten Straße starke Abnutzung eingetreten ist, über die Straßenoberfläche mehr oder weniger herausragen und so ein erhebliches Verkehrshindernis bilden, ganz abgesehen davon, daß auch die Schachtdeckel selbst durch die eingetretene Veränderung erhöhter Inanspruchnahme ausgesetzt sind, welche zu deren Zerstörung führen kann. Diesem Ubelstand hilft die vorliegende Neuerung durch die Verstellbarkeit des Deckels ab.The novelty of the invention is that the lid, including the frame on which it rests, can easily be changed in altitude. Through this invention ίο the evil is countered that the manhole cover, if the surrounding them Pavement sags over time or when on a gravel road heavy wear has occurred, more or less protruding from the road surface and thus constitute a considerable obstacle to traffic, quite apart from the fact that the Manhole cover itself exposed to increased use due to the change that has occurred which can lead to their destruction. The present one helps with this problem Innovation through the adjustability of the lid.
Wie diese bewirkt wird, veranschaulicht die Zeichnung, und zwar zeigtHow this is effected, the drawing illustrates, namely shows
Fig. ι einen Vertikalschnitt in der Mittellinie des Schachtdeckels mit dem Unterlagsrahmen, Fig. Ι a vertical section in the center line of the manhole cover with the support frame,
Fig. 2 eine Draufsicht auf den Unterlagsrahmen unter Fortlassung des in Fig. 1 im Schnitt dargestellten Straßenpflasters sowie des Schachtdeckels und des Schachtrahmens.Fig. 2 is a plan view of the support frame omitting the in Fig. 1 in Section shown street pavement as well as the manhole cover and the manhole frame.
Der Schachtdeckel 1 ruht auf dem Schachtrahmen 2. Der Schachtrahmen 2 liegt auf einer Sandbettung 3, welche den Unterlagsrahmen 4 ausfüllt.The manhole cover 1 rests on the manhole frame 2. The manhole frame 2 lies on one Sand bedding 3, which fills the support frame 4.
Der Unterlagsrahmen 4 ist mit einem nach unten gerichteten Steg 12 versehen, welcher mit Versteifungsrippen 5 ausgestattet ist und eine seitliche Verschiebung des Unterlagsrahmens hintanhält. Um die Sandbettung 3 nach oben hin abzuschließen, wird diese mit einer Goudronschicht 6 gedichtet. Der Unterlagsrahmen 4 ruht mittels eines Zementringes 7 auf dem bei Schachtbauten meist verwandten Zementbetonformstück S und wird außerdem durch eine Betonunterlage 9 gehalten. Bei gemauerten Schächten ist die Ausbildung des Unterlagsrahmens eine entsprechend einfachere.The support frame 4 is provided with a downwardly directed web 12, which is equipped with stiffening ribs 5 and a lateral displacement of the support frame stops. In order to complete the sand bed 3 towards the top, this is done with a Goudron layer 6 sealed. The support frame 4 rests by means of a cement ring 7 on the cement-concrete fitting S, which is mostly used in shaft constructions, and is also held by a concrete base 9. In the case of masonry manholes, the formation of the Underlay frame a correspondingly simpler one.
Die Wirkungsweise dieses Schachtdeckels mit Unterlagsrahmen ist die folgende:The mode of action of this manhole cover with support frame is as follows:
Tritt eine Sackung des Straßenpflasters ein, welche eine Absenkung des Schachtdeckels wünschenswert erscheinen läßt, so wird die Dichtung 6 beseitigt, und von der Sandbettung 3 wird so viel entfernt, wie zur richtigen Einstellung des Schachtdeckels erforderlich ist. Die Dichtung wird alsdann erneuert.If the pavement subsides, which causes the manhole cover to sink appears desirable, the seal 6 is eliminated, and from the sand bed 3 is removed as much as is necessary for correct adjustment of the manhole cover. The seal is then renewed.
