The molded part is designed in the form of a puncture molded part that comprises a guide made of displaced plastic material, where the guide defines the openings on both sides.

Description

Die Erfindung betrifft eine Revisionsabdeckung, gemaß Anspruch 1.The invention relates to a revision cover, according to claim 1.

Eine solche Revisionsabdeckung wird im Großen und Ganzen in der DE 35 17 836 A1 vorgestellt. Dort erkennt man in der Fig. 13 eine umlaufende Nut, welche als Ausformung im zugehörigen Deckelprofil für die teilweise oder vollständige Halterung bzw. Festlegung der Dämmplatte im Revisionsdeckel sorgt.Such a revision coverage will be broadly in the DE 35 17 836 A1 presented. There, one recognizes in Fig. 13 a circumferential groove, which provides as a molding in the associated cover profile for the partial or complete support or fixing the insulation board in the inspection cover.

Bekanntermaßen finden sich Revisionsabdeckungen in Wänden, Decken oder sogar auch Böden, um den Zugang zu beispielsweise elektrischen oder sanitären Installationen hinter korrespondierenden Verkleidungen zu ermöglichen. Da solche Verkleidungen vielfach und in wachsender Stückzahl eingesetzt werden, ist mit einem ständig steigenden Bedarf an Revisionsabdeckungen zu rechnen.As is known, there are inspection covers in walls, ceilings or even floors to allow access to, for example, electrical or sanitary installations behind corresponding panels. Since such panels are used many times and in increasing quantities, a constantly increasing demand for inspection covers can be expected.

Dabei kommt es bei sämtlichen Anwendungsfällen darauf an, die üblicherweise in den Revisionsdeckel eingesetzte Dämmplatte fluchtend im Vergleich zum Deckelprofil anzuordnen. Vergleichbares gilt natürlich auch für mit dem Rahmenprofil gegebenenfalls zu verbindende Dämmplatten. Eine solche fluchtende Anordnung ist schon aus optischen Gründen nicht nur wünschenswert, sondern unbedingt erforderlich. Um dies zu erreichen, liefert der Stand der Technik mit der EP 0 567 731 B1 eine überzeugende Lösung. Hier verfügt der Deckelrahmen bzw. das Deckelprofil über eine Füllung aus Spachtelmasse. Die Dämmplatte wird nun derart in die Spachtelmasse eingedrückt, dass sie in der erhärtenden Spachtelmasse mit dem Deckelprofil bzw. einem zugehörigen Rahmenschenkel des Deckelprofils fluchtet und so das gewünschte Erscheinungsbild erzeugt und dauerhaft realisiert wird. Das hat sich bewährt.It depends on all applications, it is important to arrange the insulation board usually used in the inspection cover in alignment with the cover profile. Of course, the same also applies to the frame profile optionally to be connected insulation boards. Such an aligned arrangement is not only desirable for optical reasons, but absolutely necessary. To achieve this, the prior art provides with the EP 0 567 731 B1 a convincing solution. Here, the lid frame or the lid profile has a filling made of filler. The insulation board is now pressed into the filler so that they are in the hardening putty with the cover profile or an associated frame legs of the cover profile is aligned and thus produces the desired appearance and is permanently realized. That has proven itself.

In der praktischen Umsetzung bei der Herstellung der Revisionsabdeckung hat sich jedoch herausgestellt, dass während der Abbindezeit der Spachtelmasse bzw. allgemein eines an dieser Stelle eingesetzten Adhäsivmittels eine Weiter verarbeitung der Revisionsabdeckung nicht oder nur schwerlich möglich ist. Andernfalls würde man riskieren, dass die flächenbündige und zumeist auch zentrierte Ausrichtung der Dämmplatte im Vergleich zum Revisionsdeckel bzw. dessen Deckelprofil verloren geht und im Extremfall die Revisionsabdeckung aus optischen Gründen nicht mehr verbaut werden kann. Da heutzutage zunehmend kurze Fertigungs- und Montagezeiten gefordert werden, stellt sich die beschriebene Abbindezeit als Hindernis auf dem Weg dorthin dar.In the practical implementation in the preparation of the inspection cover has been found, however, that during the setting time of the filler or generally used at this point adhesive agent further processing of the inspection cover is not or only with difficulty. Otherwise you would risk that the flush and mostly centered orientation of the insulation board is lost in comparison to the inspection cover or its cover profile and in extreme cases, the inspection cover for visual reasons can not be installed. Since nowadays increasingly short production and assembly times are required, the described setting time presents itself as an obstacle on the way there.

Das gilt grundsätzlich auch für die ebenfalls gattungsbildende Lehre nach der EP 1 514 980 A1 . Denn an dieser Stelle verfügt ein Auflagerschenkel beispielsweise über eine Riffelung unter Bildung einer Aufnahmenut für Klebstoff. Alternativ hierzu kann der Auflagerschenkel auf seiner Innenseite mit gegen die Dämmplatte gerichteten Distanzkrallen ausgerüstet werden, die bis zum Fluchten der Dämmplatte mit dem Rahmenschenkel in die Dämmplatte eingedrungen sind. Der zwischen dem Auflagerschenkel und der Dämmplatte verbleibende Zwischenraum dient zur Aufnahme von Klebstoff.This also applies in principle to the likewise generic teaching according to the EP 1 514 980 A1 , Because at this point has a support leg, for example, a corrugation to form a receiving groove for adhesive. Alternatively, the support leg can be equipped on its inside with directed against the insulation board spacer claws, which have penetrated to the alignment of the insulation board with the frame legs in the insulation board. The remaining between the support leg and the insulating plate gap is used to hold adhesive.

Der Erfindung liegt das technische Problem zugrunde, eine Revisionsabdeckung der eingangs beschriebenen Ausgestaltung so weiter zu entwickeln, dass insbesondere die Herstellungszeit verringert ist und eine einwandfreie Halterung der Dämmplatte gelingt. Außerdem soll ein zugehöriges Herstellungsverfahren angegeben werden.The invention is based on the technical problem of further developing a revision cover of the embodiment described at the beginning in such a way that, in particular, the production time is reduced and a perfect mounting of the insulating panel succeeds. In addition, an associated manufacturing process should be specified.

Zur Lösung dieser technischen Problemstellung schlägt die Erfindung bei einer gattungsgemäßen Revisionsabdeckung vor, dass die wenigstens eine Ausformung in dem Profil (Rahmenprofil und/oder Deckelprofil) als Durchstoßausformung ausgebildet ist, welche zwei beidseitig einer Öffnung definierte Zungen aus plastisch verdrängtem Material des Profils aufweist, wobei die Durchstoßausformung jeweils punktuell am Sichtschenkel angeordnet ist. - Meistens sind mehrere Durchstoßausformungen in Längserstreckung des Profils realisiert.To solve this technical problem, the invention proposes in a generic revision cover, that the at least one formation in the profile (frame profile and / or cover profile) is formed as Durchstoßausformung, which has two sides of an opening defined tongues of plastically displaced material of the profile, said the puncture formation is arranged in each case at points on the leg view. - In most cases, several Durchstoßausformungen be realized in the longitudinal extension of the profile.

Eine solche Durchstoßausformung meint im Rahmen der Erfindung eine Ausformung im Profil, die durch einen plastischen Umformvorgang des Profils hervorgerufen wird, und zwar mit Hilfe eines Werkzeuges, welches zu diesem Zweck das fragliche Profil durchdringt bzw. durchstößt. Bei dem Werkzeug mag es sich um einen Dom und hier beispielsweise und nicht einschränkend um einen sogenannten Crimpstichel handeln. In jedem Fall ist die wenigstens eine Durchstoßausformung nur punktuell sowie seitlich des Profils (Rahmenprofil und/oder Deckelprofil) vorgesehen und ausdrücklich nicht als durchlaufende Nut ausgeführt, wie sie die DE 35 17 836 A1 als gattungsbildender Stand der Technik lehrt.Such Durchstoßausformung means in the context of the invention, a molding in the profile, which is caused by a plastic forming process of the profile, with the aid of a tool which penetrates or pierces the questionable profile for this purpose. The tool may be a dome and here, for example and not by way of limitation, may be a so-called crimping stylus. In any case, the at least one puncture formation is provided only at points and laterally of the profile (frame profile and / or cover profile) and expressly not designed as a continuous groove, as they DE 35 17 836 A1 teaches as a generic state of the art.

Dadurch sind keine besonderen Anforderungen an die Fertigungsgenauigkeit zu stellen, weil die Dämmplatte und das zugehörige Profil letztlich nur punktuell miteinander durch jeweils plastische Verformung verbunden werden. Es kommt lediglich darauf an, das Profil und die Dämmplatte vor dem beschriebenen Fügeverfahren gegenseitig auszurichten. Meistens wird man die Dämmplatte gegenüber dem umlaufenden Profil zentriert anordnen und im Übrigen flächenbündig, was die Oberfläche der Dämmplatte im Vergleich zum Rahmenschenkel bzw. Sichtschenkel des Profils angeht, wie dies grundsätzlich in der EP 0 567 731 B1 beschrieben wird. Sobald diese gegenseitige Ausrichtung vorgenommen wurde, sorgen die mehreren Durchstoßausformungen im Profil dafür, dass die Dämmplatte und das Profil in dieser zentrierten und flächenbündigen gegenseitigen Ausrichtung miteinander verbunden werden.As a result, no special demands on the manufacturing accuracy to make because the insulation board and the associated profile are ultimately only selectively connected to each other by each plastic deformation. It is only important to align the profile and the insulation board before the described joining process each other. In most cases, you will arrange the insulation board centered with respect to the circumferential profile and, moreover, flush, as far as the surface of the insulation board in comparison to the frame leg or leg of the profile, as this basically in the EP 0 567 731 B1 is described. Once this alignment has been made, the multiple puncture shapes in the profile provide ensuring that the insulation board and the profile are connected together in this centered and flush alignment.

Tatsächlich werden bei dem beschriebenen Fügeverfahren beide Komponenten, d. h. das Profil (Rahmenprofil und/oder Deckelprofil) und die Dämmplatte, durch plastische Verformung miteinander verbunden. Insofern kann man bei diesem Verfahrensschritt auch von einem Crimpen bzw. einem Crimpverfahren sprechen. Denn die fragliche Verbindung lässt sich nur bedingt lösen und ist meistens nicht reparabel. Solche Anforderungen spielen für den vorliegenden Verwendungszweck ohnehin keine Rolle.In fact, in the described joining process both components, i. H. the profile (frame profile and / or cover profile) and the insulation board, connected by plastic deformation. In this respect one can also speak of a crimping or a crimping process in this process step. Because the connection in question can be solved only conditionally and is usually not repairable. Such requirements play no role for the present purpose anyway.

Jedenfalls lassen sich durch die gegenseitige Ausrichtung von Profil und Dämmplatte problemlos Fertigungstoleranzen sowohl des jeweiligen Profils als auch der zugehörigen Dämmplatte (in gewissen Grenzen) ausgleichen. Im Vergleich zu bisherigen Vorgehensweisen kann sogar mit größeren Fertigungstoleranzen für das Profil sowie gegebenenfalls die Dämmplatte gearbeitet werden, so dass die Herstellungskosten der erfindungsgemäßen Revisionsabdeckung verringert sind. - Grundsätzlich wird natürlich auch eine Halterung der Dämmplatte an dem jeweiligen Profil mit abgedeckt, bei welcher die Dämmplatte nicht plastisch verformt wird, sondern nur das Profil im Bereich der Durchstoßausformung.In any case, can be easily compensated by the mutual alignment of profile and insulation board manufacturing tolerances of both the respective profile and the associated insulation board (within certain limits). Compared to previous approaches can be used even with larger manufacturing tolerances for the profile and optionally the insulation board, so that the manufacturing cost of the revision cover according to the invention are reduced. - Basically, of course, a holder of the insulation board is covered with the respective profile, in which the insulation board is not plastically deformed, but only the profile in the area of Durchstoßausformung.

Nach vorteilhafter Ausgestaltung ist die Durchstoßausformung bzw. sind die mehreren Durchstoßausformungen jeweils rahmeninnenseitig des Profils (Rahmenprofil und/oder Deckelprofil) realisiert. Meistens finden sich jeweils zwei Durchstoßausformungen über Eck, wobei wenigstens zwei Ecken des Profils eine Berücksichtigung erfahren bzw. entsprechend ausgebildet sind.According to an advantageous embodiment, the puncture formation or the multiple puncture formations in each case frame inside the profile (frame profile and / or cover profile) is realized. In most cases, there are in each case two puncture formations over the corner, wherein at least two corners of the profile are given consideration or are designed accordingly.

Die jeweilige Zunge der beiden beidseitig der Öffnung definierten Zungen aus dem plastisch verdrängten Material des Profils greift in die Dämmplatte zu deren Halterung am Profil (Rahmenprofil und/oder Deckelprofil) ein. Bei diesem Vorgang wird die Dämmplatte meistens (aber nicht notwendigerweise) ebenfalls plastisch verformt, so dass beide Komponenten (Dämmplatte und Profil) durch das beschriebene Fügeverfahren miteinander die gewünschte Verbindung eingehen.The respective tongue of the two tongues defined on both sides of the opening from the plastically displaced material of the profile engages in the insulating panel their support on the profile (frame profile and / or cover profile) a. In this process, the insulating board is usually (but not necessarily) also plastically deformed, so that both components (insulation board and profile) by the joining method described together enter into the desired connection.

Nach einer Ausgestaltung der Erfindung, welcher besondere Bedeutung zukommt, ist vorgesehen, dass die Dämmplatte mittels eines Adhäsivmittels und zusätzlich unter Rückgriff auf die wenigstens eine Durchstoßausformung am Profil gehalten wird. In der Regel wird zunächst das Adhäsivmittel auf das betreffende Profil aufgebracht, dann die Dämmplatte vorteilhaft ausgerichtet (beispielsweise zentriert und/oder flächenbündig) und abschließend mit Hilfe der einen oder der mehreren Durchstoßausformungen fixiert. Dadurch kann die Adhäsiwerbindung zwischen der Dämmplatte und dem Profil problemlos abbinden und es besteht beispielsweise nicht die Gefahr, dass sich während dieses Vor ganges die Dämmplatte gegenüber dem Profil verschiebt. Auch ein Absinken der Dämmplatte innerhalb des Profils durch Verlust oder Schwund von Klebstofflösungsmittel wird im Rahmen der Erfindung verhindert.According to one embodiment of the invention, which is of particular importance, it is provided that the insulating board is held by means of an adhesive agent and additionally by resorting to the at least one Durchstoßausformung the profile. As a rule, the adhesive agent is first applied to the respective profile, then the insulation board is advantageously aligned (for example, centered and / or flush-mounted) and finally fixed with the aid of the one or more puncture formations. As a result, the Adhäsiwerbindung between the insulation board and the profile easily set and, for example, there is no risk that shifts the insulation board relative to the profile during this transition before. Also, a sinking of the insulation board within the profile by loss or loss of adhesive solvent is prevented in the invention.

Des Weiteren ist es nicht oder nicht mehr erforderlich, prozessbeschleunigende Maßnahmen für das Abbinden einzusetzen, wie z. B. eine Wärmebehandlung. Vielmehr kann auf einfache und kostengünstig strukturierte Adhäsivmittel zurückgegriffen werden. In jedem Fall reicht die Fixierung der Dämmplatte im Profil oder am Profil aus, damit an diese Fixierung anschließende Fertigungsprozesse unmittelbar vollzogen werden können, ohne dass die Abbindezeit des Adhäsivmittels abgewartet werden muss. Für die endgültige Stabilität der Adhäsiwerbindung kann dann gegebenenfalls noch der Lagerzeitraum der Revisionsabdeckung genutzt werden. - Dabei versteht es sich, dass die Adhäsivverbindung und der damit verbundene Rückgriff auf ein Adhäsivmittel nur eine Option darstellen und für die Funktionsweise nicht zwingend erforderlich sind.Furthermore, it is not or no longer necessary to use process-accelerating measures for the setting, such. B. a heat treatment. Rather, it is possible to resort to simple and inexpensive structured adhesive. In any case, the fixation of the insulation board in the profile or on the profile, so that subsequent to this fixation manufacturing processes can be performed immediately without the setting time of the adhesive must be awaited. For the final stability of the Adhäsiwerbindung then possibly the storage period of the revision cover can be used. It is understood that the adhesive connection and the associated use of an adhesive agent are only an option and are not absolutely necessary for the mode of operation.

Gegenstand der Erfindung ist auch ein Verfahren zur Herstellung einer Revisionsabdeckung, wie sie zuvor im Detail beschrieben worden ist. Bei dem Verfahren wird die Ausformung als Durchstoßausformung mit zwei beidseitig einer Öffnung definierten Zungen aus plastisch verdrängtem Material des Profils ausgebildet, wodurch das Profil (Rahmenprofil und/oder Deckelprofil) und die Dämmplatte (oder die mehreren Dämmplatten) unter jeweiliger plastischer Verformung miteinander verbunden werden. Bei dem Werkzeug, um die jeweilige Durchstoßausformung definieren zu können, handelt es sich vorteilhaft um einen Dom, beispielsweise einen Crimpstichel. Dieser Dom bzw. Crimpstichel durchstößt das Profil und erzeugt wenigstens eine in die Dämmplatte eindringende Zunge infolge der damit verbundenen Materialverdrängung.The invention also provides a method for producing a revision cover, as has been described in detail above. In the method, the molding is formed as Durchstoßausformung with two defined on both sides of an opening tongues of plastically displaced material of the profile, whereby the profile (frame profile and / or cover profile) and the insulation board (or the plurality of insulation boards) are connected to each other under respective plastic deformation. The tool in order to be able to define the respective puncture formation is advantageously a dome, for example a crimping stylus. This dome or crimp pierces the profile and generates at least one tongue penetrating into the insulation board due to the associated material displacement.

Insgesamt wird das Profil vorteilhaft zunächst mit der bereits angesprochenen Füllung aus dem Adhäsivmittel ausgerüstet. Daran anschließend wird die Dämmplatte in das Profil ein- oder auf dieses aufgelegt und gegebenenfalls ausgerichtet (zentriert und/oder flächenbündig). Um nun diese Ausrichtung zu fixieren, wird die Dämmplatte mit Hilfe der eingebrachten Durchstoßausformung oder der mehreren Durchstoßausformungen mit dem Profil zusätzlich (zu dem Adhäsivmittel) verbunden. Dadurch lässt sich der Herstellungsvorgang verkürzen und sind insgesamt die Kosten verringert.Overall, the profile is advantageously equipped first with the already mentioned filling of the adhesive agent. Subsequently, the insulation board in the profile on or placed on this and optionally aligned (centered and / or flush). In order to fix this alignment, the insulation board is additionally connected to the profile (with the aid of the introduced puncture formation or the multiple puncture formations) (to the adhesive agent). As a result, the manufacturing process can be shortened and the overall costs are reduced.

Der Revisionsrahmen 1 verfügt über ein Rahmenprofil 3 mit Auflagerschenkel 3a und Sichtschenkel 3b. In gleicher Weise ist der Revisionsdeckel 2 mit einem Deckelprofil 4 ausgerüstet, welches in vergleichbarer Weise einen Auflagerschenkel 4a und einen Sichtschenkel 4b aufweist.In the figures, a revision cover is shown, which is equipped in its basic structure with a revision frame 1 and an insertable into the inspection frame inspection cover 2.

In dem Revisionsdeckel 2 wird im Rahmen des Ausführungsbeispiels und nicht einschränkend eine Dämmplatte 5 aufgenommen, bei welcher es sich um eine Gipskartonplatte oder eine andere Platte aus einem geräusche- und/oder feuerdämmenden Material handelt. Im Rahmen des Ausführungsbeispiels ist lediglich das Deckelprofil 4 mit einer in die Dämmplatte 5 eingreifenden Ausformung 6 ausgerüstet. Grundsätzlich könnte auch das Rahmenprofil 3 mit einer solchen Ausformung 6 versehen werden, um hiermit weitere Dämmplatten 5 zu verbinden. Das ist jedoch nicht dargestellt.In the inspection cover 2, an insulating plate 5 is included within the scope of the embodiment and not limiting, which is a gypsum board or other plate of a noise and / or fire-retardant material. In the context of the embodiment, only the cover profile 4 is equipped with a recess 6 engaging in the insulating panel 6. In principle, the frame profile 3 could be provided with such a molding 6, to hereby connect more insulation boards 5. This is not shown.

Bei der Ausformung 6 handelt es sich erfindungsgemäß um eine Durchstoßausformung 6, also eine solche, die mit Hilfe eines in der Fig. 3 dargestellten Werkzeuges in dem Profil 3, 4 (Rahmenprofil 3 und/oder Deckelprofil 4) definiert wird, indem das betreffende Profil 3, 4 bzw. 4 im Beispielfall durchstoßen wird. Bei dem Werkzeug handelt sich um einen Dom 7, im Ausführungsbeispiel einen Crimpstichel 7, welcher in der Lage ist, das meistens aus Aluminium gefertigte Profil 4 bzw. 3, 4 zu durchdringen. Bei diesem Vorgang wird die Durchstoßausformung 6 definiert, weiche ausweislich einer vergleichenden Betrachtung der Fig. 2 und 3 mit einer Öffnung 6a und beidseitigen Zungen 6b aus plastisch verdrängtem Material des Deckelprofils 4 im Ausführungsbeispiel ausgerüstet ist.In the formation 6 is according to the invention to a puncture formation 6, that is, one with the aid of a in the Fig. 3 Tool shown in the profile 3, 4 (frame profile 3 and / or cover profile 4) is defined by the respective profile 3, 4 and 4 is pierced in the example case. The tool is a dome 7, in the embodiment a crimping die 7, which is able to penetrate the profile 4 or 3, 4, which is usually made of aluminum. In this process, the puncture formation 6 is defined, which can be seen from a comparative analysis of the FIGS. 2 and 3 is equipped with an opening 6a and two-sided tongues 6b of plastically displaced material of the cover profile 4 in the embodiment.

Die jeweilige Zunge 6b bzw. die beiden beidseitig der Öffnung 6a der Durchstoßausformung 6 vorgesehenen Zungen 6b greifen in die Dämmplatte 5 zu deren Halterung am Deckelprofil 4 ein. Die Fig. 1 macht deutlich, dass jeweils zwei Durchstoßausformungen 6 über Eck des Deckelprofils 4 realisiert sind. Außerdem hat sich bewährt, wenigstens zwei und darüber hinaus gegenüberliegende Ecken des Deckelprofils 4 mit den entsprechenden und Ober Eck angeordneten Durchstoßausformungen 6 auszurüsten.The respective tongue 6b or the two tongues 6b provided on both sides of the opening 6a of the puncture formation 6 engage in the insulation board 5 for mounting on the cover profile 4. The Fig. 1 makes it clear that two Durchstoßausformungen 6 are realized on the corner of the cover profile 4. It has also proven itself, at least two and beyond opposite corners of the cover profile 4 with the corresponding and upper corner arranged puncture moldings 6 equip.

Denn auf diese Weise ist es möglich, die Dämmplatte 5 im Vergleich zum umlaufenden Deckelprofil 4 zentriert auszurichten, d. h. unter Berücksichtigung eines gleichen oder nahezu gleichen umlaufenden Spaltes zwischen der Dämmplatte 5 und dem Deckelprofil 4. Außerdem gewährleistet eine solche Anordnung und punktuelle Verbindung der Dämmplatte 5 mit dem Deckelprofil 4, dass die Dämmplatte 5 flächenbündig im Vergleich zum Sichtschenkel 4b des Deckelprofils 4 angeordnet ist, wie die Schnittdarstellung nach Fig. 2 deutlich macht. Das heißt, die Oberfläche der Dämmplatte 5 und eine kopfseitige Stirnfläche des Sichtschenkels 4b sind in etwa in einer Ebene angeordnet, woraus die Flächenbondigkeit resultiert.Because in this way it is possible to align the insulation board 5 centered compared to the circumferential cover profile 4, ie, taking into account a same or almost the same circumferential gap between the insulation board 5 and the cover profile 4. In addition, such an arrangement and selective connection of the insulation board 5 ensures with the cover profile 4, that the insulation board 5 is arranged flush with the surface in comparison to the visible leg 4b of the cover profile 4, as the sectional view to Fig. 2 makes it clear. That is, the surface of the insulating board 5 and a head-side end face of the sighting leg 4b are arranged approximately in a plane, resulting in the surface bonding.

Beim Eindringen des Domes bzw. Crimpstichels 7 in das Deckelprofil 4 werden nicht nur die beiden Zungen 6b aus plastisch verdrängtem Material beidseitig der Öffnung 6a der Durchstoßausformung 6 definiert, sondern dringen die Zungen 6b auch in die Dämmplatte 5 ein und verformen diese ebenfalls plastisch. Das ist jedoch nicht zwingend, weil die Dämmplatte 5 im Eindringbereich grundsätzlich auch mit einer Einformung ausgerüstet werden kann.When penetrating the dome or crimping pin 7 in the cover profile 4 not only the two tongues 6b are defined by plastically displaced material on both sides of the opening 6a of Durchstoßausformung 6, but penetrate the tongues 6b also in the insulation board 5 and deform them also plastically. However, this is not mandatory, because the insulation board 5 in the penetration can basically be equipped with a molding.

Mit dem Dom bzw. Crimpstichel 7 wird allgemein ein Fügeverfahren vorgenommen, bei dem zwei Komponenten (die Dämmplatte 5 und das Deckelprofil 4 im Beispielfall) durch eine plastische Verformung miteinander im Sinne einer Crimpverbindung eine Kopplung eingehen. Dazu sind die Durchstoßausformungen 6 jeweils punktuell am Deckelprofil 4 und gegebenenfalls am Rahmenprofil 3 angeordnet, und zwar größtenteils mittig im Vergleich zur Querschnittshöhe des zugehörigen Sichtschenkels 4b respektive 3b. Ihre Verteilung in Längsrichtung des Sichtschenkels 4b bzw. 3b ist so gewählt, dass die Durchstoßausformungen 6 jeweils über Eck angeordnet sind, wie dies die Fig. 1 andeutet.With the dome or crimping die 7, a joining process is generally carried out in which two components (the insulating panel 5 and the cover profile 4 in the example case) undergo a coupling by means of a plastic deformation in the sense of a crimped connection. For this purpose, the puncture formations 6 are each arranged at points on the cover profile 4 and possibly on the frame profile 3, largely centrally in comparison to the cross-sectional height of the associated visible leg 4b and 3b, respectively. Their distribution in the longitudinal direction of the leg 4b and 3b is so chosen that the Durchstoßausformungen 6 are each arranged over the corner, as the Fig. 1 suggests.

Bevor die Durchstoßausformungen 6 definiert werden und hierdurch die Fügeverbindung zu der Dämmplatte 5 hergestellt und diese eine Fixierung gegenüber dem Deckelprofil 4 respektive dem Revisionsdeckel 2 im Ganzen erfährt, wird zunächst das Profil 3, 4 bzw. das Deckelprofil 4 mit einer Füllung aus einem Adhäsivmittel 8 ausgerüstet, die man in der Fig. 2 erkennt. Bei dieser Füllung aus dem Adhäsivmittel 8 mag es sich um Spachtelmasse oder ein vergleichbares aushärtendes Adhäsivmittel handeln. Auf das Adhäsivmittel 8 wird die Dämmplatte 5 aufgelegt bzw. in dieses eingelegt. Anschließend wird die Dämmplatte 5 gegenüber dem Deckelprofil 4 im Beispielfall zentriert ausgerichtet und flächenbündig platziert. Erst dann erfährt die Dämmplatte 5 die beschriebene Fixierung mit Hilfe der Durchstoßausformungen 6 im Deckelprofil 4.Before the Durchstoßausformungen 6 are defined and thereby produces the joint connection to the insulation board 5 and this undergoes a fixation relative to the cover profile 4 respectively the inspection cover 2 as a whole, first the profile 3, 4 or the cover profile 4 with a filling of an adhesive agent equipped in the Fig. 2 recognizes. This filling of the adhesive 8 may be putty or a comparable hardening adhesive. On the Adhäsivmittel 8, the insulation board 5 is placed or inserted into this. Subsequently, the insulation board 5 is aligned with respect to the cover profile 4 centered in the example and placed flush. Only then undergoes the insulation board 5 described fixation using the puncture moldings 6 in the cover profile. 4

Auf diese Weise kann das zunächst noch flüssige Adhäsivmittel 8 aushärten (auch auf langen Zeitskalen), ohne dass sich die zentrierte und flächenbündige Ausrichtung der Dämmplatte 5 gegenüber dem Deckelprofil 4 nachfolgend noch ändert. Das heißt, der Revisionsdeckel 2 ist unmittelbar für weitere Verarbeitungsschritte geeignet und vorbereitet, beispielsweise für die Anbringung von scharnieren. Verschlüssen, Fangvorrichtungen etc,. Etwaige Herstellungs- und Verfahrensverzögerungen werden nicht beobachtet.In this way, the first still liquid adhesive agent 8 cure (even on long time scales), without the centered and flush alignment of the insulation board 5 relative to the cover profile 4 below changes. That is, the inspection cover 2 is immediately suitable and prepared for further processing steps, for example for the attachment of hinges. Closures, safety gears etc ,. Any manufacturing and process delays are not observed.
