- the manhole cover is inserted into the framework offset in the frame and screwed to the frame.
- upstanding sleeves are provided in the tub corners of the tub bottom of the manhole cover, which are penetrated by the mounting screws to engage in a provided in the frame area female thread.
- a sealing cord which is inserted in a circumferential Zargen- or lid groove, resulting in the odor and water resistance of the manhole cover.
- a disadvantage is the comparatively high weight of the concrete filling of the manhole cover.
- a tub which is composed of a profile frame and a trough bottom used in the profile frame, the trough bottom, especially the function of a lost formwork for the subsequent filling of the tub with concrete or lightweight concrete, but should not fulfill carrier functions.
- US 6 036 401 A a manhole cover of a honeycomb structured, bolted to a cover plate body for a height-adjustable shaft part.
- the cover plate is sealed in the region of a protruding edge via a seal with the adjustable shaft part.
- This manhole cover can take over the loads of the cover plate due to the concavely curved base body and its honeycomb-like structure.
- JP-2002201657-A and CN-2719923-Y Further disclose each manhole covers with a support plate from a honeycomb core, while GB-2308148-A discloses a generic manhole cover.

Description
Die Erfindung bezieht sich auf eine Schachtabdeckung mit einer in einem Baukörper versetzbaren Zarge sowie mit einem in die Zarge einsetzbaren und mit der Zarge verschraubbaren Schachtdeckel, der einen Profilrahmen und eine vom Profilrahmen umschlossene Tragplatte zur Aufnahme eines Bodenbelages umfaßt.The invention relates to a manhole cover with a displaceable in a building frame and with a usable in the frame and screwed to the frame manhole cover comprising a profile frame and a frame enclosed by the profile support plate for receiving a floor covering.
Bei üblichen Schachtabdeckungen dieser Art weist der Schachtdeckel eine Blechwanne auf, die mit Beton ausgegossen wird und auf der Betonfüllung einen Fußbodenbelag aufnimmt, um eine sich über den Bereich der Schachtabdeckung erstreckende einheitliche Bodenausgestaltung des Baukörpers zu ermöglichen. Der Schachtdeckel wird in die im Baukörper versetzte Zarge eingesetzt und mit der Zarge verschraubt. Zu diesem Zweck sind in den Wannenecken vom Wannenboden des Schachtdeckels aufragende Hülsen vorgesehen, die von den Befestigungsschrauben durchsetzt werden, um in ein im Zargenbereich vorgesehenes Muttergewinde einzugreifen. Durch eine Dichtungsschnur, die in eine umlaufende Zargen- oder Deckelnut eingelegt ist, ergibt sich die Geruchs- und Wasserdichtheit der Schachtabdeckung. Nachteilig ist allerdings das vergleichsweise hohe Gewicht der Betonfüllung des Schachtdeckels. Es ist zwar bereits bekannt, die Wanne mit Leichtbeton zu füllen, doch bleibt die damit erreichbare Gewichtseinsparung beschränkt, weil auf eine Bewehrung der Betonfüllung nicht verzichtet werden kann, wenn der Bodenplatte der Wanne des Schachtdeckels nicht die Aufgabe zukommen soll, einen wesentlichen Anteil der Lastabtragung zu übernehmen. Im Hinblick auf eine einfache Fertigung wird eine Wanne angestrebt, die sich aus einem Profilrahmen und einem in den Profilrahmen eingesetzten Wannenboden zusammensetzt, wobei der Wannenboden vor allem die Funktion einer verlorenen Schalung für die nachträgliche Befüllung der Wanne mit Beton bzw. Leichtbeton, nicht aber Trägerfunktionen erfüllen soll.In conventional manhole covers of this type, the manhole cover a sheet pan, which is poured with concrete and receives on the concrete filling a floor covering to allow over the area of the manhole cover extending uniform floor design of the building. The manhole cover is inserted into the framework offset in the frame and screwed to the frame. For this purpose, upstanding sleeves are provided in the tub corners of the tub bottom of the manhole cover, which are penetrated by the mounting screws to engage in a provided in the frame area female thread. By a sealing cord, which is inserted in a circumferential Zargen- or lid groove, resulting in the odor and water resistance of the manhole cover. However, a disadvantage is the comparatively high weight of the concrete filling of the manhole cover. Although it is already known to fill the tub with lightweight concrete, but the achievable weight savings remains limited, because a reinforcement of the concrete filling can not be waived if the bottom plate of the tub of the manhole cover should not be given the task, a significant proportion of load transfer to take over. In terms of ease of manufacture, a tub is sought, which is composed of a profile frame and a trough bottom used in the profile frame, the trough bottom, especially the function of a lost formwork for the subsequent filling of the tub with concrete or lightweight concrete, but should not fulfill carrier functions.
Darüber hinaus offenbart die
Die
Der Erfindung liegt somit die Aufgabe zugrunde, eine Schachtabdeckung der eingangs geschilderten Art so auszugestalten, daß bei einem geringen Eigengewicht einfache Konstruktionsbedingungen für die Wanne des Schachtdeckels gewährleistet werden können, ohne auf eine wasser- und geruchsdichte Schachtabdeckung verzichten zu müssen.The invention is therefore the object of a manhole cover of the type described in such a way that at a low weight simple design conditions for the tub of the manhole cover can be guaranteed without having to give up a water and odor-tight manhole cover.
Die Erfindung löst die gestellte Aufgabe dadurch, daß die unter Zwischenlage einer Dichtung in den Profilrahmen eingesetzte Tragplatte aus einem Wabenkern mit einer oberen und einer unteren Deckschicht besteht.The invention solves this problem by the fact that the support plate used with the interposition of a seal in the profile frame consists of a honeycomb core with an upper and a lower cover layer.
Da zufolge dieser Maßnahmen auf eine Betonfüllung überhaupt verzichtet und die bewehrte Betonplatte durch eine Tragplatte aus einem Wabenkern mit einer oberen und einer unteren Deckschicht ersetzt wird, bedarf es nicht einmal eines eine verlorene Schalung bildenden Wannenbodens, so daß die entsprechend den lichten Innenabmessungen des Profilrahmens zugeschnittene Tragplatte lediglich in den Profilrahmen eingesetzt zu werden braucht. Damit sind alle Voraussetzungen für eine außergewöhnliche Gewichtseinsparung erfüllt, weil nicht nur die Tragplatte aufgrund des Wabenkernes ein selbst im Vergleich zu einer bewehrten Leichtbetonfüllung erheblich geringeres Gewicht aufweist, sondern zusätzlich auch auf einen sonst erforderlichen Wannenboden verzichtet werden kann. Der Wabenkern bildet mit den anliegenden, einen Ober- und einen Untergurt ergebenden Deckschichten einen Verbundkörper, der die Auflasten ohne weiteres über den Profilrahmen auf die Zarge und über die Zarge auf den Baukörper abtragen kann, so daß keine unzulässige Abnahme der Traglast zu befürchten ist. Trotz des Fehlens eines Wannenbodens bleibt die Wasser- und Geruchsdichtheit des Schachtdeckels gewahrt, wenn die Tragplatte unter Zwischenlage einer Dichtung in den Profilrahmen eingesetzt wird. Diese Dichtung kann sowohl auf der Oberseite als auch auf der Unterseite der Tragplatte vorgesehen sein. Besonders einfache Konstruktionsverhältnisse ergeben sich in diesem Zusammenhang, wenn die Dichtung aus einer Klebeschicht besteht, weil in diesem Fall keine zusätzlichen Maßnahmen erforderlich werden, um die Tragplatte im Profilrahmen festzuhalten. Die Aufgabe der flüssigkeits- und geruchsdichten Verbindung zwischen der Tragplatte und dem Profilrahmen kann durch die Klebeschicht vorteilhaft übernommen werden.As a result of these measures dispensed with a concrete filling at all and the reinforced concrete slab is replaced by a support plate from a honeycomb core with an upper and a lower cover layer, it does not even require a permanent formwork forming tub bottom, so that tailored according to the clear internal dimensions of the profile frame Support plate needs to be used only in the profile frame. Thus, all the requirements for an extraordinary weight saving are met, because not only the support plate due to the honeycomb core has a considerably lower weight even compared to a reinforced lightweight concrete filling, but also can be dispensed with an otherwise required pan bottom. The honeycomb core forms with the adjacent, a top and a bottom flange resulting cover layers a composite body that can pay off the loads easily on the profile frame on the frame and on the frame on the building so that no unacceptable decrease in the load is to be feared. Despite the lack of a tub floor, the water and odor-tightness of the manhole cover is maintained when the support plate is inserted with the interposition of a seal in the profile frame. This seal can be provided both on the top and on the underside of the support plate. Particularly simple construction conditions arise in this context, when the seal of a Adhesive layer is because in this case no additional measures are required to hold the support plate in the profile frame. The task of liquid and odor-tight connection between the support plate and the profile frame can be advantageously taken over by the adhesive layer.
In der Zeichnung ist der Erfindungsgegenstand beispielsweise dargestellt, und zwar wird eine erfindungsgemäße Schachtabdeckung in einem vereinfachten Axialschnitt gezeigt.In the drawing, the subject invention is illustrated, for example, and that a manhole cover according to the invention is shown in a simplified axial section.
Die Schachtabdeckung gemäß dem dargestellten Ausführungsbeispiel besteht aus einer im Bereich einer Schachtöffnung 1 in einem Baukörper 2 versetzten Zarge 3, in die ein Schachtdeckel 4 eingesetzt wird. Dieser Schachtdeckel 4 umfaßt einen aus einzelnen stranggepreßten Profilen 5 vorzugsweise aus Aluminium zusammengesetzten Profilrahmen 6, der auf seiner Unterseite Auflageflansche 7 für eine in den Profilrahmen 6 eingesetzte Tragplatte 8 bildet. Dieser Tragplatte 8 ist als Verbundkörper mit einem Wabenkern 9 und einer oberen und unteren Deckschicht 10 ausgebildet. Der Wabenkern 9 kann mit im Querschnitt sechseckigen Waben hergestellt werden, obwohl selbstverständlich auch andere Wabenformen möglich sind. Es kommt ja lediglich darauf an, daß entsprechende Auflasten über die Tragplatte 8 auf den Profilrahmen 6 und von diesem über die Zarge 3 auf den Baukörper 2 abgetragen werden, ohne eine Überlastung der Tragplatte 8 befürchten zu müssen. Die Deckschichten 10 wirken nicht nur als Ober- und Untergurt eines durch die Tragplatte 8 gebildeten Trägers, sondern machen die Tragplatte auch wasser- bzw. geruchsdicht. Abgesehen davon kann auf die Tragplatte 8 ein Bodenbelag unmittelbar in den Deckel 4 eingeklebt werden. In der Zeichnung ist ein solcher Bodenbelag in Form einer Verfließung 11 des Baukörpers 2 angedeutet. Die Verfließung 11 kann sich demnach im wesentlichen unbeeinträchtigt über den Schachtdeckel 4 fortsetzen. Der über die Tragplatte 8 vorstehende, die Umfangsbegrenzung des Schachtdeckels 4 bildende Rand des Profilrahmens ist aus diesem Grund auch in seiner Höhe an übliche Dicken eines Bodenbelages angepaßt.The manhole cover according to the illustrated embodiment consists of a in the region of a
Damit der Schachtdeckel 4, der gegenüber der Zarge 3 mit Hilfe einer in eine Nut 12 des Profilrahmens 6 eingelegten Dichtungsschnur 13 abgedichtet wird, selbst wasser- und geruchsdicht ausgebildet werden kann, ist die Tragplatte 8 unter Zwischenlage einer Dichtung 14 in den Profilrahmen 6 eingesetzt. Diese Dichtung 14 ist als Klebeschicht ausgebildet, mit deren Hilfe die Tragplatte 8 im Profilrahmen 6 gehalten wird, so daß sich gesonderte Halterungen erübrigen, was eine Konstruktionsvereinfachung mit sich bringt.So that the
Die Verschraubung des Schachtdeckels 4 mit der Zarge 3 erfolgt in üblicher Weise mit Hilfe von Befestigungsschrauben 15, die im Eckbereich des Schachtdeckels 4 vorgesehen sind und in Gewindemuttern 16 eingreifen, die in einer Hohlkammer der Zarge 3 eingegossen sind.The screwing of the
Aufgrund der lediglich in den Profilrahmen 6 eingesetzten Tragplatte 8 wird eine einfache, gewichtssparende Konstruktion erreicht, wobei die Tragplatte 8 zufolge ihres Aufbaus ohne zusätzliche Bewehrung die auftretenden Auflasten aufnehmen kann. Dies bedeutet außerdem eine wesentliche Montagevereinfachung, weil die Notwendigkeit entfällt, eine mit einer Bewehrung versehene Wanne vor Ort mit Beton ausgießen zu müssen, bevor nach einem Aushärten der Betonfüllung ein Bodenbelag verlegt werden kann. Der jeweilige Bodenbelag kann ja unmittelbar auf die Tragplatte zum Beispiel durch ein Kleben aufgebracht werden.Due to the
