Dämpfungsring (2) für Kanalschachtdeckel (4)DESCRIPTION
Rolf Liehr
Damping ring (2) for manhole cover (4)
Die Erfindung bezieht sich auf einen Dämpfungsring (2) mit rechtwinkliger Aufkantung (1) aus Polyäthylen, der in einem Schachtrahmen (3) zur Auflage für einen Kanalschachtdeckel (4) dient.The invention relates to a damping ring (2) with a rectangular edge (1) made of polyethylene, which serves in a manhole frame (3) to support a sewer manhole cover (4).
Dieser Ring, auch Antiklapperring genannt, ist seit Jahren im Einsatz, hat jedoch außenseitig keine rechtwinklige Aufkantung. Das zur Herstel lung zur Anwendung kommende Material besitzt nicht die notwendige Elastizität und wird bei kalter Jahreszeit steif und spröde.This ring, also known as an anti-rattle ring, has been in use for years, but does not have a right-angled edge on the outside. The material used to make it does not have the necessary elasticity and becomes stiff and brittle in the cold season.
Ein NachteSlbei den bisher zur Anwendung gekommenen Ringen ist das Fehlen der außenseitigen rechtwinkligen Aufkantung, wodurch der Kanalschachtdeckel (4-), der in dem Schacht rahm en (3) liegt, während des darüberrollenden Straßenverkehrs hin und her geschoben,wird. Das hat zur Folge, daß einerseits die. Auflagefläche des Kanalschachtdeckels und andererseits die des Schachtrahmens im Laufe der. Zeit einem Verschleiß unterliegen, wodurch das Klappern des Deckels hervorgerufen wird. ;A disadvantage of the rings used so far is the lack of a rectangular edge on the outside, which means that the manhole cover (4-), which lies in the manhole frame (3), is pushed back and forth by the traffic driving over it. This means that the support surface of the manhole cover and the manhole frame are subject to wear over time, which causes the cover to rattle.
Ein dazwischen gelegter Ring ohne Aufkantung wird durch beschriebenen Vorgang stark in Mitleidenschaft gezogen, wodurch nur eine kurze Lebensdauer für den Ring gegeben iot. Hinzu kommt, daß die ohne Aufkantung versehenen Ringe aus Materialien hergestellt werden, die nicht die entsprechende Shore Härte bei gleichzeitig notwendiger Elastizität besitzen, wodurch ein weiterer erhöhter Verschleiß, sowohl des Ringes als auch der Auflageflächen von Schachtrahmen (3) und Kanalschachtdeckel U) erfolgt»A ring without a raised edge placed between them is severely affected by the process described, which means that the ring only has a short lifespan. In addition, the rings without a raised edge are made of materials that do not have the appropriate Shore hardness and the necessary elasticity, which leads to further increased wear, both on the ring and on the contact surfaces of the manhole frame (3) and manhole cover (U)»
Der Erfindung liegt die Aufgabe zugrunde, vorstehend genannte Nachteile zu beseitigen und einen Ring zu schaffen, der ein Verschieben des Kanalschachtdeckels (O im Schachtrahmen (3) verhindert, in Verbindung mit hohen Festigkeiten und trotzdem elastischen Verhaltens. Hierdurch wird der Verschleiß des Ringes (2), des Schachtrahmens (3) und des Kanalschachtdegkels (O und das dadurch hervorgerufene Klappern beseitigt.The invention is based on the object of eliminating the above-mentioned disadvantages and of creating a ring which prevents the manhole cover (O ) from moving in the manhole frame (3), in conjunction with high strengths and yet elastic behavior. This eliminates the wear of the ring (2), the manhole frame (3) and the manhole cover (O) and the rattling caused thereby.

Dieses Ziel wird durch die außenseitige rechtwinklige Aufkantung (1) in Verbindung mit einem Polyäthylenmaterial, namens Lotrene, erreicht. Eine Shore D Härte von 55 und ein Elastizitätsmodul von 220 MPa geben die Gewähr für eine hohe Abriebfestigkeit in Verbindung mit einer höchstmöglichen Elastizität. In der Zeichnung ist der Erfindungsgegenstand in einem Ausführungsbeispiel im Schnitt dargestellt.This goal is achieved by the external right-angled edge (1) in conjunction with a polyethylene material called Lotrene. A Shore D hardness of 55 and an elastic modulus of 220 MPa guarantee high abrasion resistance in conjunction with the highest possible elasticity. The drawing shows the subject matter of the invention in section in an embodiment.
