Abstract

A vehicle roof, partic. of a bus, is sound- and heat-insulated, using an inner ceiling of polyurethane foam. This is pressed during heat-treatment so as to reduce its thickness by half at least, glass-fibre cloth being glued to its top and bottom surfaces, together with a sound-permeable cover on the visible side. The foam is initially about 20mm thick, and it is perforated before compression. The max. wt. of the glass-fibre cloth is roughly 200 g/m2, and glass fibres of predetermined thickness are inserted in it to give a sound-permeable structure. This allows sound to penetrate to panels of open-pored sound-absorbent and heat-insulating foam material, behind and clear of the inner ceiling, and fixed by supports to the inside of the roof. ADVANTAGE - Lightweight, easy handling, and increases usable height of internal space.

Description

Die Erfindung betrifft eine Vorrichtung zur deckenseitigen Ge­ räusch- und Wärmedämmung in einem Fahrzeug, insbesondere Omni­ bus, bestehend aus einer Innendecke aus wärme- und schalldäm­ menden PU-Schaum, dem im Zuge eines mit einer Wärmebehandlung einhergehenden Freßvorgangs, bei dem die Schaumstoffstärke min­ destens um die Hälfte reduziert wird, ober- und unterseitig ein Glasfaservlies und zur Sichtseite darüber hinaus noch eine schalldurchlässige Abdeckung unter Klebstoffbeigabe angelagert wird.The invention relates to a device for ceiling Ge Noise and thermal insulation in a vehicle, especially Omni bus, consisting of an inner ceiling made of heat and sound insulation PU foam, which in the course of a heat treatment accompanying eating process, in which the foam thickness min is reduced by half at the top and bottom a glass fiber fleece and one more on the visible side Sound-permeable cover attached with the addition of adhesive becomes.

Eine derartige, als "Thermoformschaumdecke" bezeichnete Innen­ decke mit selbsttragenden Eigenschaften, bei der die Ausgangs­ dicke des PU-Schaumes ca. 80 mm beträgt, die auf ca. 40 mm re­ duziert wird, ist bekannt. Durch die verbleibende PU-Schaum­ dicke weist diese Innendecke eine ausreichende Schallabsorpti­ onsfähigkeit auf, jedoch tritt eine merkbare Reduzierung der nutzbaren Innenraumhöhe auf und die verhältnismäßig schwere Innendecke ist infolge ihres insbesondere beim Einsatz in ei­ nem Omnibus gegebenen Gewichtes nur schwer handhabbar und da­ mit montierbar.Such an interior, referred to as a "thermoforming foam blanket" ceiling with self-supporting properties where the output The thickness of the PU foam is approx. 80 mm, which is approx. 40 mm right is known. Through the remaining PU foam thick, this inner ceiling has sufficient sound absorption ability, but there is a noticeable reduction in usable interior height and the relatively heavy Inner ceiling is due to their particular use in egg nem given weight omnibus difficult to handle and there with mountable.

Aufgabe der Erfindung ist es, die nutzbare Innenraumhöhe zu vergrößern und durch eine Gewichtsreduzierung die Handhabbar­ keit der Innendecke bei zumindest gleichbleibenden Trageigen­ schaften zu verbessern und gleichzeitig dafür Sorge zu tragen, daß die Geräusch- und Wärmedämmung keine Verschlechterung er­ fährt.The object of the invention is to increase the usable interior height enlarge and manageable by reducing weight speed of the inner ceiling with at least constant stretcher improve and at the same time ensure  that the noise and thermal insulation no deterioration he moves.

Diese Aufgabe wird bei einer Vorrichtung zur deckenseitigen Geräusch- und Wärmedämmung in einem Kraftwagen gemäß dem Ober­ begriff des Patentanspruches durch dessen kennzeichnende Merk­ male gelöst.This task is carried out in a device for the ceiling Noise and heat insulation in a motor vehicle according to the waiter Concept of the claim by its characteristic note times solved.

Die erfindungsgemäße Innendecke, deren PU-Schaum von einer Aus­ gangsstärke von ca. 20 mm auf ca. 6 mm zusammengepreßt wird, ist äußerst formstabil und weist immer noch wärme- und schall­ dämmende Eigenschaften in begrenztem Umfange auf. Die dachsei­ tig in den durch Quer-, Längs- und/oder Diagonalspriegeln be­ grenzten Feldern angeordneten schallabsorbierenden und wärme­ isolierenden Schaumplatten beanspruchen keinen zusätzlichen Raum und der zwischen Innendecke und Schaumplatten angestrebte Abstand von ca. 20 mm läßt sich leicht dadurch einhalten, daß die Querspriegel um dieses Maß über die Längs- und Diagonal­ spriegel überstehen und als Befestigungsbasis für die Innen­ decke herangezogen werden.The interior ceiling according to the invention, the PU foam of one is compressed from approx. 20 mm to approx. 6 mm, is extremely dimensionally stable and still exhibits heat and sound insulating properties to a limited extent. The badger tig be in the by transverse, longitudinal and / or diagonal brackets bordered fields arranged sound absorbing and heat insulating foam sheets do not require any additional Space and the desired between the interior ceiling and foam panels Distance of approx. 20 mm can easily be maintained by the fact that the crossbars by this dimension over the longitudinal and diagonal protrude bow and as a fastening base for the interior ceiling can be used.

Ein Ausführungsbeispiel der Erfindung wird nachfolgend anhand der Zeichnung näher erläutert.An embodiment of the invention is described below the drawing explained in more detail.

Die Darstellung zeigt einen in Fahrzeuglängsrichtung verlaufen­ den Schnitt durch einen Deckbereich eines nicht näher darge­ stellten Omnibusses und gibt einen Abschnitt einer Innendecke 1 wieder, der an einem Querspriegel 2 zur Anlage gebracht und dort durch nicht dargestellte Mittel wie Klammern befestigt ist. Der Querspriegel 2 bildet einen Teil eines Spriegelver­ bandes 3, der noch Längsspriegel 4 und nicht gezeigte Diago­ nalspriegel umfaßt. Überdeckt wird der Spriegelverband 3 durch eine Dachbeplankung 5, an deren Dachinnenseite 6 in den durch den Spriegelverband 3 umgrenzten Feldern ein geräusch- und wärmedämmender Schaum 7 angelagert ist.The illustration shows a running in the vehicle longitudinal direction, the section through a deck area of a bus, not shown, and shows a section of an inner ceiling 1 , which is brought to bear on a transverse bow 2 and fastened there by means not shown, such as clips. The cross bow 2 forms part of a Spriegelver band 3 , the longitudinal bow 4 and Diago nalspriegel includes. The bow frame 3 is covered by a roof covering 5 , on the inside of the roof 6 in which a noise and heat-insulating foam 7 is deposited in the fields delimited by the bow frame 3 .

Die Höhe der Längsspriegel 4 entspricht der Dicke des Schaumes 7 und da die Querspriegel 2 die Längsspriegel 4 überragen, ist der Schaum 7 mit Abstand der Innendecke l nachgeschaltet. Diese besteht aus einem PU-Schaum 8, dessen Ausgangsstärke etwa 20 mm beträgt und der mit einer gleichmäßigen Lochung 9 versehen ist. Ober- und unterseitig wird der PU-Schaum 8 von jeweils einem Glasfaservlies 10 begrenzt, das eine Gewichtsobergrenze von ca. 200 g/m2 aufweist und das mit einer schalldurchlässigen Struk­ tur versehen ist, was dadurch erreicht ist, daß die Glasfaser­ stärke so gewählt wird, daß bezogen auf die vorgegebene Ge­ wichtsobergrenze zwischen den einzelnen Glasfasern gerade noch eine freie Schalldurchtrittsmöglichkeit verbleibt.The height of the longitudinal bow 4 corresponds to the thickness of the foam 7 and since the transverse bow 2 projects beyond the longitudinal bow 4 , the foam 7 is connected at a distance from the inner ceiling 1. This consists of a PU foam 8 , the initial thickness of which is approximately 20 mm and which is provided with a uniform perforation 9 . The top and bottom of the PU foam 8 is each limited by a glass fiber fleece 10 , which has an upper weight limit of about 200 g / m 2 and which is provided with a sound-permeable structure, which is achieved in that the glass fiber strength is chosen so is that based on the predetermined weight limit Ge between the individual glass fibers just a free passage of sound remains.

Zum Fahrgastraum 11 hin folgt auf das zugeordnete Glasfaser­ vlies 10 eine Abdeckung 12, die aus einer gelochten Dekor­ schicht oder einem Stoffbezug bestehen kann. Unter Beigabe von Klebstoff sind die Glasfaservliese 10 und die Abdeckung 12 am PU-Schaum 8 bzw. untereinander angelagert und werden im Zuge eines mit einer Wärmebehandlung einhergehenden Freßvorganges, bei dem unter Beibehaltung des Lochdurchmessers der Lochung 9 der PU-Schaum 8 bis auf 6 mm zusammengedrückt wird, fest mit­ einander verbunden, so daß eine vorgefertigte, leicht hand­ habbare und durch rückseitig angeklebte, nicht gezeigte Halter leicht befestigbare Baueinheit geschaffen wird.Towards the passenger compartment 11 , the associated glass fiber fleece 10 is followed by a cover 12 , which may consist of a perforated decor layer or a fabric cover. With the addition of adhesive, the glass fiber nonwovens 10 and the cover 12 are attached to the PU foam 8 or to one another and are in the course of a seizure process associated with a heat treatment in which the PU foam 8 is maintained down to 6 mm while maintaining the hole diameter of the perforation 9 is compressed, firmly connected to each other, so that a prefabricated, easy-to-handle and easily attachable by rear-mounted, not shown holder is created.

Die durch die geringere Masse und die verhältnismäßig hohe Dichte des komprimierten PU-Schaumes 8 verbleibende Schallab­ sorptionsfähigkeit wird dadurch auf das gewünschte Maß ge­ bracht, daß Schall durch die Lochung 9 in den nachfolgenden Hohlraum 13 tritt und vom nachgeschalteten Schaum 7, der zudem noch gute Wärmedämmeigenschaften aufweist, absorbiert wird.The remaining mass due to the lower mass and the relatively high density of the compressed PU foam 8 Schallab sorption is brought to the desired level that sound passes through the perforation 9 in the subsequent cavity 13 and from the downstream foam 7 , which is also still good Has thermal insulation properties is absorbed.
