Abstract

The polyurethane foam for the cavity between two welded steel plates making up the wall unit is augmented by coarse-grain waste material from old vehicle tyres or similar products. The purpose is to reduce material costs, and to add greater stiffness and stability to the wall unit.

Description

Bauelement Die Erfindung bezieht sich auf ein aue luftundurchlässigen* vorzugsweise motallischen Werkstoffen bestehenden Platten in Verbindung mit Kunststoffen hergestelltes Bauelement nach Patent ........ (Patentanmeldung B 82 986 V/37b). Component The invention relates to an outside air-impermeable * preferably metal-based panels in connection with plastics Manufactured component according to patent ........ (patent application B 82 986 V / 37b).

Das Hauptpatent bezieht sich auf Wandelemente, die aus im wesentlichen luftundurchlässigen Platten bestehen, wobei der Zwischenraum zwischen diesen Platten mit schäumbarem Kunatstoff ausgeschäumt ist. In den Platten sind d&bei Öffnungen vorgesehen, die einen Luftdurchtritt durch das Wandelement gestatten und darüber hinaus eine Verankerung des ausgeschäumten Kunststoffes gewährleisten. Die vorliegende Erfindung bezweckt, die Eigenschaften solcher Platten zu verbessern und vor allem ihre Heratellung wesentlich zu serbilligen. Die Erfindung besteht insbesondere darin, daß dem schäumbaren Kunststoff grobkörnige Füllkörper beigefügt sind, die aus billigem Werkstoff, vorzugsweise Altmaterial bestehen. Als Füllstoffe kommen vorzugsweiee Körner au Altgummi, Kunstkautschukabfällen oder ähnlichem Material in Frage. Beispielsweise können nach der Erfindung alte Autoreifen verwendet werden, die durch Reißen, Stanzen oder Schneiden su entsprechenden geeigneten Körnungen zerkleinert werden. Durch geeignete Dosierung und geeignete Wahl der Zuschlagstoffe und der verwendeten Körnungen ist dabei eine beliebige Anpassung an die jeweiliges Aniorderungen von Schalldichtung und Wärmeisolierung möglich. Im Ubrigen kann durch Beimischung von Fasern, vorzugsweise Kunststofffasern, zum schäumenden Kunststoff eine zusätzliche Versteigung der Wandelemente gegen Schubkräfte erreicht werden.The main patent relates to wall elements that essentially consist of air-impermeable panels are made, with the space between these panels is filled with foamable plastic. In the plates there are d & at openings provided that allow air to pass through the wall element and above also ensure anchoring of the foamed plastic. The present Invention aims to improve the properties of such panels and above all to substantially discount their manufacture. The invention consists in particular in that the foamable plastic coarse-grained packing are attached, which are cheap Material, preferably old material. The fillers used are preferably white Grains from old rubber, synthetic rubber waste or similar material in question. For example old car tires can be used according to the invention, which by tearing, punching or cutting su appropriate suitable grain size. By suitable dosage and suitable choice of aggregates and the grain sizes used is any adaptation to the respective requirements of soundproofing and thermal insulation possible. Otherwise, by admixing fibers, preferably Plastic fibers, an additional reinforcement of the wall elements in addition to the foaming plastic can be achieved against shear forces.

Nach der vorliegenden Erfindung können auch luftundurchlässige, vorzugsweise aue Stahlblech bestehende Platten einseitig mit geeigneten Püllstoffen vermengten schäumbsren Kunststoffen beschichtet werden. Die Stärke der verwendeten perforierten Platten wird dabei Je nach der Qualität des verwendeten schäumbaren Kunststoffes so bemessen, daß die erforderliche Festigkeit der beschichteten Platte gewährleistet ist. In besonderen Fällen können, wenn der schäumbare Kunststoff mit dem verwendeten Füllstoff selbst eine ausreichende Festigkeit ergibt, geringe Wand stärken ausreichen.According to the present invention, air-impermeable, preferably Existing sheets of steel were mixed on one side with suitable fillers foamed plastics are coated. The strength of the perforated used Plates are made depending on the quality of the foamable plastic used dimensioned so that the required strength of the coated plate is ensured is. In special cases, when the foamable plastic is used with the Filler itself gives sufficient strength, small wall thicknesses are sufficient.

Gemäß einem weiteren Schritt der erfindung sollen die perforierten Platten auf der Seite, auf der sie it 6chäumbarem Kunststoff beschichtet werden, vor dem Äufschäumen eie Vorbehandlung erhalten, durch die Höcker oder Noppen gebildet werden, die die Haftfähigkeit und Stützfähigkeit zwischen schäumbarem Kunststoff und Platte verbeasern.According to a further step of the invention, the perforated Panels on the side on which they are coated with foamable plastic, Receive a pre-treatment before foaming, formed by bumps or knobs that the adhesiveness and support ability between foamable plastic and spoil the record.

Diese Vorbehandlung kann dadurch erfolgen, daß auf diese Flächen ein treibfähiger Spachtel, z.B, ein Spachtel auf Polyurethanbasis autgebracht wird oder daß auf diese Flächen ein treibiähiges, schnell reagierende Polyurethan-Schäumstoff-Rohgemisch aufgespritzt wird.This pretreatment can be done by applying a driftable spatula, e.g. a spatula based on polyurethane is applied or that on these surfaces a foaming, fast-reacting polyurethane-foam raw mixture is sprayed on.

Die Zeichnung zeigt als Ausführungsbeispiel des Erfindungsgegenstandes einen Längsechnitt durch eine Wandplatte. Hierbei sind it 1 und 2 zwei Bleche bezeichnet, die mit ihren Rändern 3, 4 bzw. 5 und 6 umgebördelt und an den Stoßstellen 7 und 8 miteinander verschweißt sind. Der auf diese Weise gebildete Hohlkörper, dessen Innenraum 9 mit schäumbarem Kunststoff, vorzugsweise Polyurethan, ausgeschäumt ist, enthalt außerdem Füllstoffkörner 10, die aus Altgummi bestehen. Die.. Körner werden durch Zerreißen alter Autoreifen hergestellt.The drawing shows an exemplary embodiment of the subject matter of the invention a longitudinal section through a wall panel. Here 1 and 2 are two sheets, the flanged with their edges 3, 4 or 5 and 6 and at the joints 7 and 8 are welded together. The hollow body formed in this way, its Inner space 9 is foamed with foamable plastic, preferably polyurethane, also contains filler grains 10, which consist of scrap rubber. The .. grains will be made by tearing old car tires.

Mit 11 sind in daß Blech 1 eingestanzte Löcher bezeichnet, die wesentlich größer als die in dem Blech 2 eingestanzten Löcher 12 und auch gegenüber diesen Löchern versetzt angeordnet sind. Der schäumbare Kunststoff quillt beim Ausschäumen des Innenraums 9 durch diese Locher nach außen, wodurch sich eine Verankerung der Kunststoffschicht ergibt.With 11 punched holes are designated in that sheet 1, which is essential larger than the holes 12 punched in the sheet metal 2 and also in relation to these Holes are arranged offset. The foamable plastic swells when it is foamed of the interior 9 through these holes to the outside, whereby an anchoring of the Plastic layer results.

Mit 13 und 14 sind Holzrahmen bezeichnet, die zur Verstärkung der Ränder der Wandplatten dienen.With 13 and 14 wooden frames are referred to to reinforce the The edges of the wall panels are used.
