Definitions
- the invention relates to sewerage articles, in particular manhole covers and street attachments, which consist of a frame embedded in the carriageway surface and an insert, in particular an inlet grate or a manhole cover.
- plan-level processing of the two contact surfaces did not lead to the desired success.
- the level support can be disturbed by warping or the ingress of dirt, which in turn leads to the tilting of the insert and finally to the abrasive wear of the contact surfaces.
- a further improvement in the form of a damping insert made of elastomer integrated in at least one support surface does not bring a permanent solution to the problem in many cases. It has been shown that the damping insert incorporates the penetrating dirt, so to speak, and then has a sanding effect on the counter surface with this dirt. The result is also selective wear of the contact surface in the frame.
- the depressions can be molded in and do not require any machining.
- the depressions can have the shape of troughs or blind holes.
- the covering is applied after the connection or filling. This can compensate for the distortion that may have occurred due to the setting of the concrete.
- the contact surfaces are then absolutely flat.
Abstract
Description
Die Erfindung befaßt sich mit Kanalisationsartikeln, insbesondere Schachtabdeckungen und Stra- ßenaufsätzen, die aus einem in der Fahrbahnfläche eingebetteten Rahmen und einem Einlegteil, also insbesondere einem Einlaufrost oder einem Schachtdeckel, bestehen.The invention relates to sewerage articles, in particular manhole covers and street attachments, which consist of a frame embedded in the carriageway surface and an insert, in particular an inlet grate or a manhole cover.
Die Belastungen des modernen Schwerlast- und Schnellverkehrs stellen hohe Anforderungen an die Lagerung des Einlegteils im Rahmen. Ist die Lagerung nicht absolut eben und vollflächig, dann kommt es durch die dynamischen Vertikal- (Federn) und Horizontalkräfte (Bremsen, Kurvenfahrt) zu Mikrobewegungen des Einlegteils, die einen Verschleiß der beiden beteiligten Auflageflächen zur Folge haben. Der Deckel bzw. Rost schlägt hörbar im Rahmen. Ein verschlissener Rahmen muß in mühevoller Arbeit ausgetauscht werden.The loads of modern heavy and fast traffic place high demands on the storage of the insert in the frame. If the bearing is not absolutely flat and full-surface, then the dynamic vertical (springs) and horizontal forces (braking, cornering) lead to micro-movements of the insert, which result in wear on the two contact surfaces involved. The lid or grate beats audibly in the frame. A worn frame has to be laboriously replaced.
Das planebene Bearbeiten der beiden Auflageflächen hat nicht zu dem gewünschten Erfolg geführt. Während des Betriebs kann die ebene Auflage durch Verzug oder das Eindringen von Schmutz gestört werden, was wiederum zum Kippen des Einlegteils und schließlich zum abrasiven Verschleiß der Auflageflächen führt.The plan-level processing of the two contact surfaces did not lead to the desired success. During operation, the level support can be disturbed by warping or the ingress of dirt, which in turn leads to the tilting of the insert and finally to the abrasive wear of the contact surfaces.
Auch eine weitere Verbesserung in Form einer in mindestens eine Auflagefläche integrierten dämpfenden Einlage aus Elastomer bringt in vielen Fällen keine dauerhafte Lösung des Problems. Es hat sich nämlich gezeigt, daß die dämpfende Einlage den eindringenden Schmutz sozusagen inkorporiert und dann mit diesem Schmutz auf die Gegenfläche schmirgelnd einwirkt. Die Folge ist auch hierein punktueller Verschleiß der Auflagefläche im Rahmen.A further improvement in the form of a damping insert made of elastomer integrated in at least one support surface does not bring a permanent solution to the problem in many cases. It has been shown that the damping insert incorporates the penetrating dirt, so to speak, and then has a sanding effect on the counter surface with this dirt. The result is also selective wear of the contact surface in the frame.
Ein weiterer Nachteil dieser Abdeckungen und Straßenaufsätze sind die hohen Herstellkosten. Das Bearbeiten der Auflageflächen und das Einarbeiten der Nut für die dämpfende Einlage ist sehr teuer. Die Aufgabe, diese Kosten zu sparen und eine sichere auf Dauer klapper- und verschleißfreie Lagerung des Einlegteils zu erreichen, wird gemäß der Erfindung nunmehr dadurch gelöst, daß die unbearbeiteten Auflageflächen vollflächig mit einer in einer Form gegossenen elastomeren Beschichtung überzogen werden. Durch das Beschichten in einer Präzisionsform ergibt sich an beiden zusammenwirkenden Flächen eine Ebenheit, die einer Bearbeitung gleichkommt und für eine absolut ruhige Lage des Einlegteils sorgt. Die Beschichtung kann so weit um den Rand des Einlegteils herumgezogen werden, daß Schmutz nicht mehr bis zur Auflagefläche vordringen und dort inkorporiert werden kann.Another disadvantage of these covers and street attachments are the high manufacturing costs. The machining of the contact surfaces and the incorporation of the groove for the damping insert is very expensive. The task of saving these costs and achieving a secure rattle and wear-free storage of the insert part in the long run is now achieved according to the invention in that the unprocessed contact surfaces are completely covered with an elastomeric coating cast in a mold. Coating in a precision mold results in a flatness on both interacting surfaces, which is equivalent to machining and ensures an absolutely quiet position of the insert. The coating can be drawn around the edge of the insert part so that dirt can no longer penetrate to the support surface and can be incorporated there.
Da es sich bei den Kanalisationsartikeln fast durchweg um Gußteile handelt, ist es zweckmäßig, den Belag sofort nach dem Erkalten der Gußteile und dem Putzen der gußrauhen Auflageflächen aufzubringen. Diese ergibt eine hervorragende Dauerbindung des Belags mit dem Metall.Since the sewerage articles are almost always cast parts, it is advisable to apply the covering immediately after the cast parts have cooled and the rough-cast support surfaces have been cleaned. This results in an excellent permanent bond between the covering and the metal.
Um die Bindung des Elastomers mit den metallisehen Auflageflächen zu verbessern, wird vorgeschlagen, in die Auflageflächen rundum- oder abschnittsweiselaufende Vertiefungen einzubringen, die mit dem Elastomer ausgegossen werden. Die Vertiefungen können mit eingeformt sein und bedürfen keiner Bearbeitung. Die Vertiefungen können die Form von Rinnen oder Sacklöchern haben.In order to improve the binding of the elastomer to the metallic support surfaces, it is proposed to provide recesses which run all around or in sections and which are poured out with the elastomer in the support surfaces. The depressions can be molded in and do not require any machining. The depressions can have the shape of troughs or blind holes.
Bei Schachtabdeckungen, deren Metallteile noch mit Beton verbunden bzw. gefüllt werden, wird der Belag nach dem Verbinden bzw. Füllen aufgebracht. Hierdurch kann der Verzug, der durch das Abbinden des Betons ggf. entstanden ist, wieder ausgeglichen werden. Die Auflageflächen sind anschließend absolut eben.In the case of manhole covers, the metal parts of which are still connected or filled with concrete, the covering is applied after the connection or filling. This can compensate for the distortion that may have occurred due to the setting of the concrete. The contact surfaces are then absolutely flat.
Das Aufbringen einer gegossenen Beschichtung ist von Steinzeugrohren her bekannt. Dort dient die Beschichtung aber der Verbesserung der Gleit- und Anlagefläche für die Muffendichtung.The application of a cast coating is known from stoneware pipes. There, however, the coating serves to improve the sliding and contact surface for the sleeve seal.
Die Beschichtung bei Kanalisationsartikeln als dämpfende Einlage und Ersatz für die mechanische Bearbeitung einzusetzen, ist überraschend neu und äußerst vorteilhaft.Using the coating for sewerage articles as a damping insert and replacement for mechanical processing is surprisingly new and extremely advantageous.
