Description

Die Erfindung betrifft eine Revisionsabdeckung mit einem Rahmen für Wand- und Deckeneinbau, mit einem in den Revisionsrahmen einsetzbaren Revisionsdeckel, wobei zum Abdichten des Spaltes zwischen Rahmenprofilen von Revisionsrahmen und Revisionsdeckel ein umlaufendes Dichtungsprofil vorhanden ist, welches bei Hitzeentwicklung aufquillt.The invention relates to a revision cover with a frame for wall and ceiling installation, with a revision cover that can be inserted into the revision frame, with a circumferential sealing profile being provided to seal the gap between the frame profiles of the revision frame and revision cover, which swells when heat develops.

Es ist eine derartige Revisionsabdeckung bekannt, bei welcher das im Brandfall aufschäumende Dichtungsprofil in einer außenliegenden Nut entweder der Rahmenprofile für den Revisionsrahmen oder für den Revisionsdeckel untergebracht ist. Diese außenliegende Unterbringung des Dichtungsprofils ist schon deshalb unbefriedigend, weil mechanische Beschädigungen nicht ausgeschlossen sind. Auch ein selbständiges Lösen des Dichtungsprofiles liegt im Bereich des Möglichen. - Hier will die Erfindung Abhilfe schaffen.Such a revision cover is known in which the sealing profile which foams up in the event of fire is accommodated in an external groove either of the frame profiles for the revision frame or for the revision cover. This external placement of the sealing profile is unsatisfactory because mechanical damage can not be excluded. Independent loosening of the sealing profile is also possible. - The invention seeks to remedy this.

Der Erfindung liegt die Aufgabe zugrunde, eine Revisionsabdeckung der eingangs beschriebenen Ausführungsform zu schaffen, bei welcher das Dichtungsprofil einwandfrei entweder in dem Revisionsrahmen oder in dem Revisionsdeckel untergebracht ist.The invention has for its object to provide a revision cover of the embodiment described above, in which the sealing profile is properly housed either in the inspection frame or in the inspection cover.

Diese Aufgabe löst die Erfindung bei einer gattungsgemäßen Revisionsabdeckung dadurch, daß das Dichtungsprofil auf der Innenseite der Rahmenprofile des Revisionsrahmens und/oder des Revisionsdeckels angeordnet ist und die den Spalt zwischen Revisionsrahmen und Revisionsdeckel bildenden Rahmenschenkel der Rahmenprofile Durchbrechungen zum Hindurchtreten des bei Hitzeeinwirkung aufquillenden bzw. im Brandfall aufschäumenden Dichtungsmaterials aufweisen. - Diese Maßnahmen der Erfindung haben zur Folge, daß das Dichtungsprofil gleichsam auf der Innenseite der Rahmenprofile von entweder Revisionsrahmen oder Revisionsdeckel angeordnet und folglich gegen Beschädigungen geschützt und gegen selbständiges Lösen gesichert ist. Die Erfindung geht von der Erkenntnis aus, daß sich die den Spalt zwischen Revisionsrahmen und Revisionsdeckel begrenzenden Rahmenschenkel derart mit Durchbrechungen versehen werden können, daß das aufquillende bzw. aufschäumende Dichtungsmaterial durch diese Durchbrechungen zur Abdichtung des Spaltes unschwer hindurchtreten kann und im übrigen diese Durchbrechungen eine Sichtkontrolle ermöglichen, ob das Dichtungsprofil tatsächlich eingelegt worden ist. Insoweit wird im Rahmen der Erfindung eine optische Qualitätskontrolle sowohl für die Fertigung als für den Benutzer verwirklicht. Das alles gelingt mit verhältnismäßig einfachen und funktionsgerechten Mitteln. - Darin sind die wesentlichen durch die Erfindung erreichten Vorteile zu sehen.This object is achieved by the invention in the case of a generic revision cover in that the sealing profile is arranged on the inside of the frame profiles of the revision frame and / or the revision cover and the frame legs of the frame profiles forming the gap between the revision frame and the revision cover have openings for the passage of heat have swelling or, in the event of fire, foaming sealing material. - These measures of the invention have the consequence that the sealing profile, as it were, arranged on the inside of the frame profiles of either inspection frames or inspection covers and consequently protected against damage and secured against independent loosening. The invention is based on the knowledge that the frame limbs delimiting the gap between the inspection frame and the inspection cover can be provided with openings such that the swelling or foaming sealing material can easily pass through these openings to seal the gap and in addition these openings provide a visual inspection enable whether the sealing profile has actually been inserted. In this respect, an optical quality control is implemented both for the production and for the user within the scope of the invention. All this can be done with relatively simple and functional means. - This shows the main advantages achieved by the invention.

Weitere erfindungswesentliche Merkmale sind im folgenden aufgeführt. So lehrt die Erfindung, daß die spaltbildenden bzw. begrenzenden Rahmenschenkel der Rahmenprofile mit einer in den Revisionsdeckel bzw. Revisionsrahmen eingesetzten Dämmplatte eine Kammer zur Aufnahme des Dichtungsprofils bilden, insoweit also eine einwandfreie Positionierung des Dichtungsprofils auf der Innenseite der Rahmenschenkel gewährleistet ist. Das gilt nach einer bevorzugten Ausführungsform der Erfindung mit selbständiger Bedeutung insbesondere dann, wenn die spaltbildenden Rahmenschenkel der Rahmenprofile mit einem umlaufenden Z-Profil eine Kammer zur Aufnahme des Dichtungsprofils bilden, wobei das Z-Profil mit seinem einen Z-Schenkel auf der in den Revisionsdeckel bzw. Revisionsrahmen eingesetzten Dämmplatte aufliegt, mit seinem anderen Z-Schenkel gegen die Rahmenschenkel anliegt bzw. gerichtet ist und mit seinem Querschenkel die Dämmplatte übergreift. Bei dieser Ausführungsform kann die Befestigung des Z-Profils sowohl an den Rahmenprofilen als auch an den Dämmplatten von Revisionsrahmen bzw. Revisionsdeckel erfolgen. - Vorzugsweise sind die Durchbrechungen in den spaltbildenden Rahmenschenkeln als Lochreihen oder Schlitzreihen ausgebildet, wobei vorgegebene Lochdurchmesser bzw. Schlitzbreiten gewählt sind, die im Brandfall ein einwandfreies Hindurchtreten des aufquillenden bzw. aufschäumenden Dichtungsprofils gewährleisten.Further features essential to the invention are listed below. Thus, the invention teaches that the gap-forming or delimiting frame legs of the frame profiles form a chamber for receiving the sealing profile with an insulating plate inserted in the inspection cover or revision frame, so that a correct positioning of the sealing profile on the inside of the frame legs is ensured. According to a preferred embodiment of the invention, this applies with independent meaning particularly when the gap-forming frame legs of the frame profiles with a circumferential Z profile Form chamber for receiving the sealing profile, the Z-profile rests with its one Z-leg on the insulation panel inserted in the inspection cover or revision frame, with its other Z-leg abuts or is directed against the frame legs and with its cross leg the insulation panel spreads. In this embodiment, the Z-profile can be attached both to the frame profiles and to the insulation panels of the inspection frame or inspection cover. - The openings in the gap-forming frame legs are preferably designed as rows of holes or rows of slots, predetermined hole diameters or slot widths being selected which ensure that the swelling or foaming sealing profile can pass through in the event of a fire.

Nach einer anderen Ausführungsform der Erfindung, der selbständige Bedeutung zukommt, ist vorgesehen, daß zumindest auf einem Rahmenprofil des Revisionsrahmens zumindest eine in Rahmenebene aufspreizbare Sicherungsfeder angeordnet ist, daß das zugeordnete Rahmenprofil des Revisionsdeckels eine Tasche zur Aufnahme eines aufgespreizten Federschenkels der Sicherungsfeder aufweist, und daß der aufspreizbare Federschenkel auf dem Rahmenprofil des Revisionsrahmens mittels eines Schmelzlotes in Ausgangsstellung zurückgehalten bzw. gespannt ist. Zwar ist es bereits bekannt, daß der Revisionsdeckel auf seiner Rückseite zumindest im Bereich eines stählernen Eckwinkels ein aufspreizbares Federblatt aufweist, welches in Ausgangsstellung mittels eines Schmelzriegels zurückgehalten ist und bei aufgeschmolzenem Schmelzriegel über den betreffenden Eckwinkel des Revisionsrahmens aufspreizt, jedoch wird dadurch eine einwandfreie Halterung des Revisionsdeckels im Brandfalle dann nicht erreicht, wenn die Revisionsabdeckung beispielsweise in eine Wand eingebaut ist. Denn dann kann der Revisionsdeckel unkontrolliert nach innen oder außen öffnen. Das wird im Rahmen der erfindungsgemäßen Maßnahmen vermieden. Stets wird der Revisionsdeckel unabhängig von seinem Scharnier und dem Deckelverschluß einwandfrei arretiert. Aus diesem Grunde empfiehlt die Erfindung weiter, daß für die Sicherungsfeder eine zum Revisionsdeckel hin offene Abdeckung vorgesehen ist, die zugleich als Niederhalter und Führung für den aufspreizbaren Federschenkel funktioniert, so daß der aufgespreizte Federschenkel tatsächlich einwandfrei in die gegenüberliegende Tasche auf dem zugeordneten Rahmenprofil des Revisionsdeckels eintritt.According to another embodiment of the invention, which is of independent importance, it is provided that at least one safety spring that can be expanded in the frame plane is arranged on at least one frame profile of the revision frame, that the associated frame profile of the inspection cover has a pocket for receiving a spread-out spring leg of the safety spring, and that the spreadable spring leg on the frame profile of the inspection frame is held back or tensioned in the starting position by means of a fusible link. Although it is already known that the inspection cover has an expandable spring leaf on its rear side, at least in the area of a steel corner bracket, which is retained in the starting position by means of a melting bar and spreads over the relevant corner bracket of the revision frame when the melting bar is melted, but this will ensure that the inspection bracket is held properly Inspection cover in Fire trap not reached if the revision cover is installed in a wall, for example. Because then the inspection cover can open inwards or outwards in an uncontrolled manner. This is avoided as part of the measures according to the invention. The inspection cover is always locked properly regardless of its hinge and the cover lock. For this reason, the invention further recommends that a cover which is open towards the inspection cover is provided for the securing spring and which also functions as a hold-down and guide for the expandable spring leg, so that the spread spring leg actually fits perfectly into the opposite pocket on the associated frame profile of the inspection cover entry.
