Description

Die Erfindung betrifft eine Revisionsabdeckung zum Verschluss einer Revisionsöffnung an Wänden, Decken, Schächten, Installations- oder Lüftungskanälen gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a revision cover for closing an inspection opening on walls, ceilings, shafts, installation or ventilation ducts according to the preamble of claim 1.

Nach der DIN 4102 - in dieser Norm ist das Brandverhalten von Baustoffen und Bauteilen geregelt - werden Baustoffe in die beiden Baustoffklassen A und B eingeteilt. Zur Baustoffklasse A gehören die nicht brennbaren Baustoffe. Die brennbaren Baustoffe werden in die Klasse B eingestuft. Die Klasse A wird weiter unterteilt. A1-Baustoffe müssen in ihrer Zusammensetzung vollständig unbrennbar sein, während A2 Baustoffe in geringem Maße brennbare Bestandteile enthalten dürfen. Hierzu gehören Bauteile, die zwar nicht selbst entzündbar sind, aber in geringem Maße brennbare Anteile enthalten: Gipskartonplatten nach DIN 18180 mit geschlossener Oberfläche oder auch Gipsfaserplatten (siehe http://www.baumarkt.de, © pw-Internet-Solutions-GmbH). Im folgenden ist mit "nicht brennbarem" Plattenmaterial stets mindestens ein Baustoff der Klasse A2 gemeint.According to DIN 4102 - in this standard the fire behavior of building materials and components is regulated - building materials are divided into the two building material classes A and B. Building material class A includes non-combustible building materials. The combustible building materials are classified in class B. Class A is subdivided further. A1 building materials must be completely non-combustible in their composition, while A2 building materials may contain a small amount of flammable components. These include components that are not themselves flammable, but contain flammable fractions to a small extent: gypsum plasterboard to DIN 18180 with a closed surface or gypsum fiber boards (see http://www.baumarkt.de, © pw-Internet-Solutions-GmbH) , In the following, "non-combustible" board material always means at least one building material of class A2.

Aus der DE 40 05 128 A1 ist eine Revisionsabdeckung bekannt, die aus einer ebenen, nicht brennbaren Platte besteht, die bis auf einen im Randbereich der Revisionsöffnung verbleibenden Spalt passgenau zu dieser ausgebildet ist, wobei im Spalt ein im Brandfall aufschäumender Dämmschichtbildner angeordnet ist. Derartige Revisionsöffnung für den Wand- und Deckeneinbau werden beispielsweise in Verbindung mit der Abdeckung von hinter einer Wand oder einer Decke eines Gebäudes befindlichen elektrischen oder sanitären Installationen eingesetzt. Da die Installationen zumindest im Notfall frei zugänglich sein müssen, werden üblicher Weise an der Wand- oder Deckenverkleidung Ausnehmungen (sogenannte Revisionsöffnung) vorgesehen, die mit einer Revisionsabdeckung versehen sind.From DE 40 05 128 A1 a revision cover is known, which consists of a flat, non-combustible plate which is formed except for a gap remaining in the edge region of the inspection gap precisely to this, wherein in the gap a frothy in case of fire intumescent is arranged. Such inspection opening for wall and ceiling installation are used for example in conjunction with the cover of located behind a wall or a ceiling of a building electrical or sanitary installations. Since the installations must be freely accessible at least in an emergency, recesses (so-called inspection opening) are usually provided on the wall or ceiling paneling, which are provided with a revision cover.

Genau wie die Wand- oder Deckenverkleidungen (siehe beispielsweise DE 201 03 972 U1) müssen die Revisionsabdeckungen eine ausreichende Feuerwiderstandsdauer aufweisen. Diese Feuerwiderstandsdauer beträgt bei feuerhemmenden Konstruktionen mindestens 30 Minuten, bei feuerbeständigen sogar mindestens 90 Minuten. Im folgenden wird stets davon ausgegangen, dass die vorgeschlagene Lösung mindestens feuerhemmend ausgebildet ist, was aber logischer Weise feuerbeständige Konstruktionen mit einschließt.Just like the wall or ceiling coverings (see, for example, DE 201 03 972 U1), the inspection covers must have a have sufficient fire resistance duration. This fire resistance time is at least 30 minutes for fire-retardant constructions, and at least 90 minutes for fire-resistant constructions. In the following, it is always assumed that the proposed solution is at least fire-retardant, but this logically includes fire-resistant constructions.

Weiterer Stand der Technik ist im übrigen in der DE-AS 16 59 608, DE 35 17 836 A1, DE 83 13 202 U1 und der DE 196 08 529 C2 offenbart.Further prior art is otherwise disclosed in DE-AS 16 59 608, DE 35 17 836 A1, DE 83 13 202 U1 and DE 196 08 529 C2.

Ausgehend von der eingangs genannten DE 40 05 128 A1, bei die Revisionsabdeckung aufwendig mittels eines metallischen Rahmens in die Revisionsöffnung eingepasst ist, liegt der Erfindung die Aufgabe zugrunde, unter Gewährleistung der geforderten Feuerwiderstandsdauer den Installations- und Materialaufwand zu verringern.Based on the aforementioned DE 40 05 128 A1, in which the inspection cover is fitted in a complicated manner by means of a metallic frame in the inspection opening, the invention has for its object to reduce the installation and material costs while ensuring the required fire resistance period.

Diese Aufgabe wird mit einer Revisionsabdeckung der eingangs genannten Art durch die im Kennzeichen des Anspruchs 1 aufgeführten Merkmale gelöst.This object is achieved with a revision cover of the type mentioned by the features listed in the characterizing part of claim 1.

Nach der Erfindung ist also vorgesehen, dass an der nicht brennbaren Platte sichtseitig eine den Spalt zwischen dem Revisionsöffnungsrand und der Platte überdeckende, vorgefertigte Abdeckplatte angeordnet und die Platte rahmenlos in die Revisionsöffnung einsetz- und mittels Befestigungselementen an deren Rand befestigbar ausgebildet ist.According to the invention it is thus provided that on the non-combustible plate on the visible side a gap between the inspection opening edge and the plate covering, prefabricated cover plate arranged and the plate frameless insertion into the inspection opening and is fastened by fasteners at the edge.

Gemäß der Erfindung entfällt somit jeglicher Rahmen für die Fixierung der Revisionsabdeckung in der Revisionsöffnung. Diese Funktion wird durch den Einsatz der erfindungsgemäß vorgefertigen Platte einschließlich der vorzugsweise aus Metall bestehenden Abdeckplatte sowie der vielfältig ausbildbaren Befestigungselemente (siehe weiter unten) realisiert, wobei die Abdeckplatte darüber hinaus zur Abdeckung des Spaltes dient.According to the invention thus eliminates any frame for the fixation of the revision cover in the inspection opening. This function is realized by the use of the prefabricated plate according to the invention, including the cover plate, which is preferably made of metal, as well as the diverse designable fastening elements (see below), the cover plate also serving to cover the gap.

Ein weiterer wesentlicher Aspekt bei einer Weiterbildung der Erfindung besteht ferner darin, dass die Revisionsabdeckung als vorgefertigtes Bauteil ausgebildet ist, d. h. vor Ort wird beim Aufbau der feuerhemmenden bzw. feuerbeständigen Wand die entsprechende Stelle gemäß den Maßen der erfindungsgemässen Revisionsabdeckung umbaut bzw. es wird ein vorgefertigtes Trennwandelement mit Revisionsöffnung aufgestellt, das einerseits genau zur ebenfalls vorzugsweise vorgefertigten Revisionsabdeckung passt und das andererseits unmittelbar mit anderen Trennwandelementen umbaubar ist. Das Trennwandelement mit Revisionsöffnung ist somit gleichzeitig Trennwand und Aufnahme für die Revisionsabdeckung. Es muss bei dieser bevorzugten Ausführungsform weder nachträglich eine entsprechende Öffnung mittels einer Säge eingebracht werden, noch muss ein Rahmen in der Öffnung fixiert werden. Diese Montagemethode wird weiter unten nochmals näher erläutert.Another essential aspect of a development of the invention further consists in that the inspection cover is designed as a prefabricated component, d. H. On site, the corresponding point according to the dimensions of the inventive revision cover is rebuilt in the construction of the fire-retardant or fire-resistant or it is a prefabricated partition wall element set up with revision that fits exactly the prefabricated revision cover on the one hand and on the other hand directly with other partition elements can be converted , The partition wall element with inspection opening is thus at the same time partition and recording for the inspection cover. It must be introduced in this preferred embodiment neither subsequently a corresponding opening by means of a saw, nor a frame must be fixed in the opening. This mounting method will be explained in more detail below.

Andere vorteilhafte Weiterbildungen ergeben sich aus den abhängigen Ansprüchen.Other advantageous developments emerge from the dependent claims.

Die erfindungsgemäße Revisionsabdeckung einschließlich ihrer vorteilhaften Weiterbildungen wird nachfolgend anhand der zeichnerischen Darstellung von mehreren Ausführungsbeispielen näher erläutert.The revision cover according to the invention including its advantageous developments will be explained in more detail with reference to the drawing of several embodiments.

Die jeweils in den Figuren 1 bis 15 dargestellte Revisionsabdeckung zum Verschluss einer Revisionsöffnung 1 an Wänden und Decken besteht im allgemeinen aus einer ebenen, nicht brennbare Platte 2, die bis auf einen im Randbereich der Revisionsöffnung 1 verbleibenden Spalt 3 passgenau zu dieser ausgebildet ist. Dabei ist vorzugsweise, aber nicht zwingend, im Spalt 3 ein im Brandfall aufschäumender Dämmschichtbildner 4, vorzugsweise sogenanntes Blähgraphit oder ein anderes Intumeszenzmaterial, angeordnet. Der Dämmschichtbildner 4 kann dabei wahlweise am Rand der Revisionsöffnung 1 oder an der Revisionsabdeckung angeordnet sein (siehe insbesondere Figuren 1, 2 und 5).The inspection cover shown in each of FIGS. 1 to 15 for closing an inspection opening 1 on walls and ceilings generally consists of a flat, non-combustible plate 2 which, with the exception of a gap 3 remaining in the edge region of the inspection opening 1, is designed to fit precisely thereto. In this case, preferably, but not necessarily, in the gap 3, an intumescent film-forming agent 4 which foams in the event of fire, preferably so-called expanded graphite or another intumescent material, is arranged. The intumescent layer 4 may optionally be arranged at the edge of the inspection opening 1 or on the inspection cover (see in particular Figures 1, 2 and 5).

Wesentlich für alle dargestellten Revisionsabdeckungen ist nun, dass an der bei einer Ausführungsform bevorzugt als vorgefertigtes Bauteil ausgebildeten Platte 2 sichtseitig (d. h. abgewandt vom abzutrennenden Revisionsraum) eine den Spalt 3 überdeckende, vorgefertigte und vorzugsweise aus Metall oder Kunststoff bestehende Abdeckplatte 5 angeordnet und die Platte 2 rahmenlos in die Revisionsöffnung 1 einsetz- und mittels der Befestigungselemente 14, vorzugsweise Schrauben 9, an deren Rand 6 befestigbar ausgebildet ist.It is essential for all illustrated inspection covers that on the preferred in one embodiment as prefabricated component plate 2 on the visible side (ie facing away from the inspection space to be separated) a gap 3 covering, prefabricated and preferably made of metal or Plastic existing cover plate 5 is arranged and the plate 2 frameless insertion into the inspection opening 1 and by means of the fastening elements 14, preferably screws 9, at the edge 6 is fastened fastened.

Mit Bezug auf die Figuren 1, 2, 5 und 11 ist dabei vorteilhaft vorgesehen, dass die Platte 2 mindestens aus zwei zueinander abgestuften Schichten 7, 8 besteht und dass der Rand 6 der Revisionsöffnung 1 zum formschlüssigen Einsatz der Abdeckung entsprechend stufig ausgebildet ist. Dem entsprechend weist auch der Spalt 3 bei zwei- oder mehrschichtiger Ausbildung der Platte 2 einen stufigen Verlauf auf. Dies ist einerseits bezüglich des Brandschutzes vorteilhaft (verbesserte Abdichtung), andererseits entspricht dies vorteilhaft auch der üblichen Aufbauweise von feuerbeständigen Wänden, die nämlich regelmäßig aus zwei zueinander versetzt montierten Schichten bestehen.With reference to FIGS. 1, 2, 5 and 11, it is advantageously provided that the plate 2 consists of at least two mutually stepped layers 7, 8, and that the edge 6 of the inspection opening 1 is configured in a correspondingly stepped manner for the positive insertion of the cover. Accordingly, the gap 3 in two- or multi-layered design of the plate 2 has a gradual course. This is on the one hand in terms of fire protection advantageous (improved sealing), on the other hand, this advantageously also corresponds to the usual structure of fire-resistant walls, namely regularly consist of two mutually offset layers mounted.

Ferner ist vorzugsweise, wie in Figur 5 dargestellt, vorgesehen, dass zwischen den Schichten 7, 8 mehrere, vorzugsweise metallische Platten 19 angeordnet sind, die zum kraftschlüssigen Verbund der Schichten 7, 8 beidseitig mit die Schichten 7, 8 durchdringenden Schrauben 20 verbunden sind, wobei zur Abstützung der Schrauben 20 auf der der vorzugsweise metallischen Abdeckplatte 5 abgewandten Seite der Revisionsabdeckung 1 weitere, vorzugsweise ebenfalls metallische Platten 21 angeordnet sind.Furthermore, it is preferably provided, as shown in FIG. 5, that several, preferably metallic, plates 19 are arranged between the layers 7, 8, which are connected to the non-positive connection of the layers 7, 8 on both sides with the screws 7, 8 penetrating through the layers 7, 8. wherein for supporting the screws 20 on the preferably metallic cover plate 5 facing away from the inspection cover 1 more, preferably also metallic plates 21 are arranged.

Bezüglich der Platte 2 ist ferner vorteilhaft vorgesehen, dass diese aus nicht brennbarem Material wie Kalziumsilikat und Kalziumsulfat besteht und mindestens 20 mm dick ausgebildet ist. Der Spalt 3 weist in diesem Fall vorzugsweise eine Breite von etwa 1 bis 8 mm auf. Wird die Revisionsöffnung vorort in die Trennwand eingebracht, kann dies beispielsweise mit einer Stich- oder Kreissäge oder einem Kreisschneider (bei runden Revisionsabdeckungen) geschehen. In diesem Fall wird der Rand der Revisionsöffnung regelmäßig nicht stufig ausgebildet sein (siehe beispielsweise Figur 12 und 14).With respect to the plate 2 is also advantageously provided that it consists of non-combustible material such as calcium silicate and calcium sulfate and is at least 20 mm thick. The gap 3 in this case preferably has a width of about 1 to 8 mm. If the inspection opening is introduced suburb in the partition, this can for example be done with a jigsaw or circular saw or a circle cutter (round inspection covers). In this case, the edge of the inspection opening will not regularly be formed in stages (see, for example, Figure 12 and 14).

Zur Befestigung der Revisionsabdeckung ist, wie besonders deutlich in Figur 2 dargestellt, vorgesehen, dass die Platte 2 mit Schrauben 9 am Rand 6 der Revisionsöffnung 1 befestigt ist. Dabei sind am Rand der Abdeckplatte 5 Durchgriffsöffnungen 13 für die Schrauben 9 eingebracht.For fastening the inspection cover is, as shown particularly clearly in Figure 2, provided that the plate 2 is secured with screws 9 at the edge 6 of the inspection opening 1. In this case, 5 through openings 13 for the screws 9 are introduced at the edge of the cover plate.

Ferner ist vorzugsweise vorgesehen (siehe Figur 5), dass die Befestigungselemente bzw. Schrauben 9 mit am Rand der Revisionsöffnung 1 angeordneten Klammern 17 in Eingriff bringbar sind, wobei die Klammern 17 den Rand der Revisionsöffnung 1 u-förmig umgreifen und an diesem vorzugsweise mit Schrauben 18 befestigt sind.Furthermore, it is preferably provided (see FIG. 5) that the fastening elements or screws 9 can be brought into engagement with clamps 17 arranged on the edge of the inspection opening 1, wherein the clamps 17 surround the edge of the inspection opening 1 in a U-shape and preferably with screws 18 are attached.

Der technische Vorteil der erfindungsgemäßen Revisionsabdekkung wird besonders deutlich, wenn man den Montagevorgang einer feuerbeständigen Trennwand mit Revisionsabdeckung betrachtet:The technical advantage of the invention Revisionsabdekkung is particularly clear when the assembly process of a fire-resistant partition with revision cover considered:

Zur feuerhemmenden bzw. feuerbeständigen Abdeckung von Rohren und Leitungen 12 (siehe Figur 1) werden zunächst vor einer Wand (oder Decke) u-förmige Schienen 11 senkrecht aufgestellt (bzw. waagerecht aufgehängt). An diesen wird eine erste Lage nicht brennbarer Platten befestigt.For fire-retardant or fire-resistant covering of pipes and conduits 12 (see FIG. 1), U-shaped rails 11 are first erected vertically (or horizontally suspended) in front of a wall (or ceiling). At these a first layer of non-combustible plates is attached.

Bei einer bevorzugten Ausführungsform mit vorgefertigem Rahmen 15, der in seinem Aufbau genau wie die Trennwand selbst ausgebildet ist, wird dieser an der gewünschten Stelle und in Fortsetzung der Trennwandplatten an den Schienen 11 befestigt. Nach dieser ersten Aufbauphase besteht die Trennwand somit aus einer ersten Schicht mit einer Revisionsöffnung, die aus einem vorgefertigen, zweischichtigen Rahmen 15 gebildet ist. Da die zweite Schicht des vorzugsweise an die Ständerkonstruktion größenangepassten Rahmens 15 stufig zur ersten angeordnet ist, kann nun die zweite Schicht der Trennwand vorteilhaft mit Versatz aufgebracht werden. In die am vorgefertigen Rahmen 15 vorgesehene Revisionsöffnung kann schließlich die ebenfalls vorzugsweise zweischichtige, abgestuft ausgebildete Revisionsabdeckung eingesetzt werden.In a preferred embodiment with prefabricated frame 15, which is formed in its structure as well as the partition itself, this is fixed at the desired location and in continuation of the partition plates on the rails 11. After this first construction phase, the partition thus consists of a first layer with a revision opening, which is formed from a prefabricated, two-layer frame 15. Since the second layer of the frame 15, which is preferably sized to the frame construction, is arranged in steps to the first one, the second layer of the separating wall can now advantageously be applied with offset. Finally, the likewise preferably two-layered, graduated-trained inspection cover can be inserted into the inspection opening provided on the prefabricated frame 15.

Bei einer anderen bevorzugten Ausführungsform (siehe Figur 6 bis 15) wird zunächst die zweite Trennwandschicht mit Versatz aufgebracht. Anschließend wird beispielsweise mit einer Sticksäge oder Kreisschneider eine Öffnung in die Wand oder Decke eingebracht, wobei der ausgeschnittene Teil um die Abdeckplatte 5 und geeignete Befestigungselemente 14 ergänzt als erfindungsgemäße Revisionsabdeckung Verwendung findet. In diesem Fall ist der Rand der Revisionsöffnung aufgrund der Schneidebearbeitung zwar nicht stufig ausgebildet, die erforderliche Abdichtfunktion wird aber auch mittels der Abdeckplatte 5 und im Spalt 3 angeordnetem Dämmschichtbildner 4 gewährleistet.In another preferred embodiment (see FIGS. 6 to 15), the second partition wall layer is first applied with offset. Subsequently, for example, with an embroidery saw or circle cutter an opening in the wall or ceiling is introduced, wherein the cut-out part to the cover plate 5 and suitable fasteners 14 complements finds invention revision cover use. In this case, the edge of the inspection opening is not staged due to the cutting processing, but the required sealing function is also ensured by means of the cover plate 5 and arranged in the gap 3 Dämmschichtbildner 4.
