Figure 00010001
Knauf Gipsplatten-Deckensysteme D11 ", January 1997) This type of facing is the panel elements placed in front of the supporting profiles a fire protection board material strip is assigned to a gap between two adjacent fire protection building boards, which strips lies against the back of the fire protection building board and is at a distance from the two associated support profiles. Properties unsatisfactory.

Eine Aufgabe der Erfindung ist es, eine Bauvorsatzschale der eingangs genannten Art zu schaffen, bei der unter Wahrung der befriedigenden Feuerschutz-Eigenschaften die Schallschutz-Eigenschaften verbessert sind. Die erfindungsgemäße Bauvorsatzschale ist, diese Aufgabe lösend, dadurch gekennzeichnet, daß die Tragprofile jeweils an der Außenseite mit Feuerschutz-PlattenmaterialStücken bemantelt sind und zwischen allen Tragprofilen, sich von Tragprofil zu Tragprofil erstreckend, den Grundprofilen Feuerschutz-Plattenmaterial-Streifen vorgesetzt sind, wobei die Feuerschutz-Plattenmaterial-Stücke an den Tragprofilen und die Feuerschutz-Plattenmaterial-Streifen an den Grundprofilen festgelegt sind, und daß die den Tragprofilen vorgesetzten Plattenelemente Schallschutz-Lochplatten sind.An object of the invention is to provide a front facing shell to create the type mentioned, while maintaining the satisfactory Fire protection properties the sound insulation properties are improved. The facing shell according to the invention is solving this problem, characterized in that the support profiles each with pieces of fire protection board material on the outside are covered and between all support profiles, from Support profile extending to support profile, the basic profiles fire protection board material strips are in front, with the fire protection plate material pieces on the support profiles and the fire protection plate material strips fixed to the basic profiles are, and that the plate elements in front of the support profiles Perforated soundproof panels are.

Bei der erfindungsgemäßen Bauvorsatzschale sind durch die vorgesetzten Lochplatten die Schallschutz-Eigenschaften verbessert bzw. befriedigend, wobei die Lochplatten, abgesehen vom Bereich der Tragprofile, auf der Rückseite schalldämmend frei sind. Das Feuerschutz-Plattenmaterial ummantelt die Tragprofile und ist im übrigen zurückverlegt zu den Grundprofilen. Die Bauhöhe der Bauvorsatzschale mit der Beplankung des Gitters ist relativ gering gehalten und nicht wesentlich vergrößert. Nur im Bereich der Tragprofile sind die Ummantelung mit Feuerschutz-Plattenmaterial und Schallschutz-Lochplatte geschichtet. Die Lochplatten entfalten die gewünschte Schalldämmwirkung, obwohl sie von den Tragprofilen hinterlegt sind. Das Feuerschutz-Plattenmaterial verläuft, entlang dem Grundprofil gesehen, nicht durchgehend eben, sondern um die Tragprofile herum ausgebogen bzw. herumgeführt. Der Raum zwischen den Tragprofilen ist genutzt.In the construction shell according to the invention are by the superior Perforated panels improve the soundproofing properties or satisfactory, the perforated plates, apart from the area of Support profiles are sound-free on the back. The fire protection board material encased the support profiles and is otherwise moved back to the basic profiles. The overall height of the facing shell with the planking of the grid is kept relatively low and not significantly enlarged. Only in the area of the support profiles are the cladding with fire protection plate material and soundproof perforated plate layered. The perforated plates unfold the desired one Soundproofing effect, although from the support profiles are deposited. The fire protection board material runs along seen the basic profile, not continuously flat, but around the Support profiles bent out or led around. The space between the support profiles is used.

Besonders zweckmäßig und vorteilhaft ist es, wenn jeweils zwischen den Feuerschutz-Plattenmaterial-Streifen und den Schallschutz-Lochplatten eine Mineralfaserlage vorgesehen ist. Die Mineralfaserlage dient primär dem Feuerschutz und hat auch Schallschutz-Wirkung. Sie nützt den Hohlraum zwischen den Tragprofilen und verbessert die Feuerschutz-Eigenschaften, ohne die Bauhöhe der Beplankung zu vergrößern. Die Mineralfaserlage ist eine Wolle" und zumeist Steinwolle.It is particularly expedient and advantageous if a mineral fiber layer is provided in each case between the fire protection plate material strips and the soundproofing perforated plates. The mineral fiber layer serves primarily for fire protection and also has a soundproofing effect. It uses the cavity between the support profiles and improves the fire protection properties without increasing the overall height of the cladding. The mineral fiber layer is one Wool "and mostly rockwool.

Besonders zweckmäßig und vorteilhaft ist es dabei, wenn die Feuerschutz-Plattenmaterial-Streifen und die Mineralfaserlagen jeweils einen geklebten Verbund bilden. Der Verbund vereinfacht die Montage der Bauvorsatzschale. Es ist das Feuerschutz-Plattenmaterial nach hinten, zum Gitter hin angeordnet und ist die Mineralfaserlage nach vorne hin, d.h. zur Sichtseite der Bauvorsatzschale gewendet angeordnet. Die Verbundplatte ist ein an sich bekanntes Bauelement und wird hier in einer neuartigen Anordnung eingesetzt. It is particularly expedient and advantageous if the fire protection plate material strips and the mineral fiber layers each form a bonded bond. The network simplifies the Assembly of the facing shell. It is the fire protection board material to the rear, arranged towards the grid and is the mineral fiber layer forward, i.e. to the visible side of the facing shell arranged upside down. The composite panel is a known one Component and is used here in a new arrangement.

Besonders zweckmäßig und vorteilhaft ist es sodann, wenn die Feuerschutz-Plattenmaterial-Streifen, auch im Verbund mit den Mineralfaserlagen, entlang den Längskanten Schnittkanten mit Schnittstruktur aufweisen. Die Streifen und gegebenenfalls die Verbundstreifen sind also durch Zerschneiden großer Platten erzeugt, wie sie zu anderen Zwecken sowieso hergestellt werden. Auch hier werden bereits vorhandene bzw. produzierte Bauelemente in einer neuartigen Anordnung eingesetzt.It is then particularly expedient and advantageous if the fire protection plate material strips, also in combination with the mineral fiber layers, along the longitudinal edges cut edges with cut structure exhibit. The strips and possibly the composite strips are generated by cutting large plates, like they are made for other purposes anyway. Here too are already existing or produced components in one new arrangement used.

Die Bauvorsatzschale wird an einer Rohbauwandung demontierbar angebracht. Die Rohbauwandung ist z.B. eine senkrechte Raumwand oder bevorzugt eine Raumdecke. An der Rohbau-Raumdecke wird die Bauvorsatzschale abgehängt und als Unterdecke bezeichnet. Die als Abhängeeinrichtungen ausgebildeten Gitteranbringungsmittel sind an sich bekannt. Bei dem Gitter sind die Grundprofile und die Tragprofile an jeder Kreuzungsstelle miteinander verbunden. Die Grundprofile und die Tragprofile bestehen in der Regel aus Metall, sind in der Regel im Querschnitt rechtwinkelig gewinkelt und bilden zumeist im Querschnitt ein U, wobei das U an den Schenkelenden frei enden kann oder mit Abwinkelungen (sogenanntes C-Profil) versehen sein kann.The facing shell can be removed from a shell appropriate. The shell is e.g. a vertical wall of the room or preferably a ceiling. On the unfinished ceiling the facing shell is suspended and called the suspended ceiling. The lattice attachment means designed as suspension devices are known per se. The basic profiles are for the grille and the support profiles at each intersection with each other connected. The basic profiles and the support profiles consist of Usually made of metal, are generally rectangular in cross section angled and usually form a U in cross section, the U can end freely at the leg ends or with bends (so-called C-profile) can be provided.

Besonders zweckmäßig und vorteilhaft ist es, wenn an der dem Gitter zugewendeten Seite der Schallschutz-Lochplatte eine Vlieslage vorgesehen ist. Die Vlieslage dient als Rieselschutz und überdeckt die Löcher der Lochplatte, ohne deren Schallschutz-Eigenschaften zu beeinträchtigen. Die Vlieslage ist z.B. im Verbund mit der Schallschutz-Lochplatte vorgesehen.It is particularly expedient and advantageous if on the grid a non-woven layer on the side of the perforated soundproofing plate is provided. The fleece layer serves as a trickle protection and covers the holes in the perforated plate, without their soundproofing properties to affect. The fleece layer is e.g. in association with the Soundproof perforated plate provided.

Eine besonders zweckmäßige und vorteilhafte Ausführungsform der Erfindung liegt vor, wenn das Gitter zwischen den den Gitteranbringungsmitteln zugeordneten Grundprofilen von Gitteranbringungsmitteln freie zusätzliche Grundprofile aufweist, an denen die Feuerschutz-Plattenmaterial-Streifen ebenfalls festgelegt sind. Diese zusätzlichen Grundprofile, die ebenfalls an den Tragprofilen festgelegt sind, dienen der Versteifung der Feuerschutz-Plattenmaterial-Streifen, die insbesondere wenn sie ummantelt sind, im Brandfall die Neigung haben, sich durchzubiegen.A particularly useful and advantageous embodiment the invention is present when the grid is between the grid attachment means assigned basic profiles of lattice attachment means has free additional basic profiles on which the fire protection board material strips are also set. These additional basic profiles, which are also on the support profiles are used to stiffen the fire protection plate material strips, which, especially if they are covered, in Fire tend to sag.

Besonders zweckmäßig und vorteilhaft ist es, wenn auf der dem Gitter zugewendeten Seite der Schallschutz-Lochplatte bzw. auf der der Lochplatte zugewendeten Seite der Feuerschutz-Plattenmaterial-Streifen zwischen den Tragprofilen Freiräume vorhanden sind, in denen Kühl/Heiz-Einrichtungen angeordnet sind. Die Kühl/Heiz-Einrichtungen, die z.B. Wärmeheizrohre oder elektrische Flächenheizelemente sind, dienen der Vervollkommnung der Bauvorsatzschale, nützen vorhandenen Freiraum in der Bauvorsatzschale und geben die Wärme/Kälte-Energie durch die Löcher der Schallschutz-Lochplatte in den Raum.It is particularly useful and advantageous if on the Grid facing side of the soundproof perforated plate or on the the side of the fire protection plate material strips facing the perforated plate there are clearances between the support profiles, in which cooling / heating devices are arranged. The cooling / heating devices, e.g. Heat pipes or electrical surface heating elements serve to perfect the facing shell, use existing space in the facing shell and give the heat / cold energy through the holes of the soundproof perforated plate in the room.

Besonders zweckmäßig und vorteilhaft ist es weiterhin, wenn die jeweils eines der Tragprofile ummantelnden Feuerschutz-Plattenmaterial-Stücke ein Quer-Streifen und zwei dazu rechtwinkelige Schenkel-Streifen sind, jeder Schenkel-Streifen unter Gehrung mit dem Quer-Streifen aneinanderliegt, die Streifen beidseitig bemantelt sind und diese Bemantelung an der Außenecke der Gehrung vom Quer-Streifen zum Schenkel-Streifen ohne Unterbrechung durchgehend ist. Es werden hier an sich bekannte (DE-Prospekt Knauf Design-Decken D19, November 1996) Bauelemente verwendet. Die beiden Schenkel-Streifen und der Querstreifen sind zunächst ein flaches Gebilde, indem sie durch V-Ausfräsungen getrennt sind, die nur an der Spitze des V die eine Bemantelung belassen. Im eingebauten Zustand sind die aneinanderliegenden Flächen der Gehrung miteinander verklebt.It is also particularly expedient and advantageous if the pieces of fire protection plate material encasing one of the support profiles are a transverse strip and two perpendicular strip strips, each miter strip lying miter with the transverse strip, the strips coated on both sides are and this cladding on the outer corner of the miter from the transverse strip to the leg strip is continuous without interruption. There are known here (DE prospectus Knauf design ceilings D19, November 1996). The two thigh stripes and the transverse stripe are initially a flat structure in that they are separated by V-shaped milled sections that only leave one covering at the tip of the V. When installed, the surfaces of the miter are glued together.

Besonders zweckmäßig und vorteilhaft ist es, wenn die Feuerschutz-Plattenmaterial-Streifen von bemantelten Bauplatten gebildet sind. Die Streifen haben dann die gleichen Eigenschaften wie die Feuerschutz-Plattenmaterial-Stücke, die die Tragprofile bedecken. Die bemantelten Bauplatten sind z.B. Gipskartonplatten oder mit Glasfaserschichten bemantelte Platten. Das Feuerschutz-Plattenmaterial der neuerungsgemäßen Bauvorsatzschale ist aber auch z.B. eine Cellulosefaserplatte oder eine zementgebundene Platte. It is particularly expedient and advantageous if the fire protection plate material strips formed by coated building boards are. The strips then have the same properties as the fire protection panels that cover the support profiles. The coated building boards are e.g. Plasterboard or panels covered with layers of glass fiber. The fire protection board material but the new construction shell is also e.g. a cellulose fiber board or a cement-bound board.

Besonders zweckmäßig und vorteilhaft ist es sodann, wenn Schrauben, welche die Feuerschutz-Plattenmaterial-Streifen an den Grundprofilen festlegen, mit den Köpfen an Durchgängen durch die Mineralfaserlage liegen. Die Durchgänge sind durch Aufreißen der Mineralfaserlage gebildet, wenn die Schrauben am Elektroschrauber durch die vorher unbeschädigte Mineralfaserlage getrieben werden.It is then particularly expedient and advantageous if screws, which the fire protection board material strips on the basic profiles fix with your heads on passages through the mineral fiber layer lie. The passages are by tearing open the Mineral fiber layer formed when the screws on the electric screwdriver through the previously undamaged mineral fiber layer.

Besonders zweckmäßig und vorteilhaft ist es weiterhin, wenn ein breiter Randbereich parallel zu den Tragprofilen oder den Grundprofilen zusätzlich vorgesehen ist, über den sich das Gitter hin erstreckt und bei dem den Tragprofilen eine Doppellage von Feuerschutz-Plattenmaterial vorgesetzt ist. Dieser zusätzliche Randbereich ist von besonderen Schallschutz-Maßnahmen, d.h. von Lochplatte frei. Es sind auch die Plattenmaterial-Streifen und die ummantelnden Plattenmaterial-Stücke weggelassen, da zum Feuerschutz die Doppellage von Feuerschutzmaterial vorgesehen ist. Der zusätzliche schallschutzfreie Randbereich an der Bauvorsatzschale dient der Regulierung der insgesamt erreichten Schallschutz-Wirkung.It is also particularly expedient and advantageous if a Wide edge area parallel to the support profiles or the basic profiles is additionally provided, over which the grid extends and in the case of the support profiles, a double layer of fire protection plate material is set. This additional border area is of special noise protection measures, i.e. of perforated plate free. There are also the strips of sheet material and the sheathing Pieces of sheet material left out because of fire protection the double layer of fire protection material is provided. The additional noise-free edge area on the facing shell serves to regulate the overall sound insulation effect achieved.

An jeder Kreuzungsstelle eines der Grundprofile 3, 4 mit einem der Tragprofile 5 ist ein Profilverbindungsmittel 7 montiert. Die Tragprofile 5 liegen mit den freien Enden der U-Schenkel 6 bzw. mit den Biegungen der C-Abwinkelungen am U-Quersteg der Grundprofile an.The facing shell according to the drawing is a suspended ceiling formed on a horizontal, not shown in Fig. 1 Unfinished ceiling suspended and enclosed by vertical Room walls 1 arranged, of which only two are shown. The Building shell has a metal grid 2, the basic profiles 3, 4 and supporting profiles 5. The basic profiles 3, 4 and Carrier profiles 5 are of identical cross-section, namely C-shaped, with a U-crossbar, two U-legs and two C-angles form. Grab on every second basic profile 3 dependent lattice attachment means 6, which lead to the structural shell ceiling to lead. At each crossing point one of the basic profiles 3, 4 with one of the support profiles 5 is a profile connection means 7 mounted. The support profiles 5 lie with the free ends of the U-legs 6 or with the bends of the C bends on the U crossbar of the basic profiles.

Jedes Tragprofil 5 ist über seine Länge an der gesamten Außenseite, d.h. an den beiden U-Schenkeln und an dem U-Quersteg mit einer Bemantelung 8 von Feuerschutz-Plattenmaterial versehen, das aus drei Stücken 9, 10, 11 zusammengesetzt ist. Das jeweils einem U-Schenkel zugeordnete Stück 9, 10 und das dem U-Quersteg zugeordnete Stück 11 stoßen unter Gehrung 12 aneinander und sind entlang der Gehrung miteinander verklebt. Die Bemantelung 8 ist mittels nicht gezeigter Schrauben an das Tragprofil 5 geheftet. Zwischen je zwei benachbarten Tragprofilen 5 ist jeweils ein Streifen 13 von Feuerschutz-Plattenmaterial vorgesehen, der einerseits gegen die Bemantelung 8 des einen Tragprofils und andererseits gegen die Bemantelung des anderen Tragprofils stößt und zwar gegen Stücke 9 bzw. 10.
