Abstract

Parent Patent No.2652001 described a structural element which has an improved heat insulation by air spaces of 4 mm left between the individual panels. The insulation capacity can be further improved by making at least the outer panel itself of insulating material. The pref. addn. is up to 95 wt.% of shredded used tyres. The rest consists of fibres, such as asbestos, wood or textiles, with an adhesive binder. In the case of concrete or gypsum, a max. of 30 wt.% of shredded rubber is recommended. Such panels are easy to cut and to install. They create a useful application for otherwise wasted used tyres.

Description

Zusatzanmeldung zur Hauptanmeldung 265001 Additional registration to main registration 265001

In der deutschen Offenlegungsch@ift Nr. 2652001 ist eine Baukonstruktion mit verbesserter Wärmeisolation beschrieben, die dadurch gekennzeichnet ist, dass die tragende Konstruktion im Abstand von etwa 4 mm mit Platten versehen ist.In the German Offenlegungssch @ ift No. 2652001 there is a building construction described with improved thermal insulation, which is characterized in that the supporting structure is provided with panels at a distance of about 4 mm.

Die verliegende Erfindung bezieht sich auf e-ine Weiterentwicklung dieser Wärmeisolation.The present invention relates to a further development this thermal insulation.

Es hat sich gezeigt,dass die Stagnation der Luft zwischen Platten und der Tragkonstruktion nach besonders unterstützt wird, wenn die Platten, vernehmlich die aussenliegenden, isolierend wirken. Dadurch wird die Aufwärmung bzw. Abkühlung einer Mauer sj stark vermindert, dass eine Wärmeübertragung auf die latten oder Tragkonstruktion zur Luftschicht Nin entweder ganz unterbunden oder zunindest stark reduziert wird. Es gibt eine grosse Anzahl van wärmedämmenden Materialien, die hierfür geeignet wären. Einer der zu verwendendel Stoffe ist Abfallgummi. Es ist bereits bekannt,Gummiabfälle ven Altreifen auf die verschiedenste Art weiter zu verwendens Vorgeschlagen wurde bereits, derartige Abfälle als Baumaterial zu benutzen. Diese Vorschläge sind jedoch in einzelnen nicht so beschrieben,dass eine tatsächliche Verwendung im Bauwesen vorgenommen werden kann.It has been shown that the stagnation of air between panels and the supporting structure is particularly supported when the panels are audible the external ones have an insulating effect. This will warm up or cool down a wall sj greatly diminished that heat transfer to the slats or Support structure to the air layer Nin either completely prevented or at least strong is reduced. There are a large number of insulating materials that can be used for this would be suitable. One of the materials to use is scrap rubber. It is already known to continue to use rubber waste ven old tires in a wide variety of ways It has already been proposed to use such waste as building material. These However, the individual suggestions are not described in such a way as to be actual Use in construction can be made.

Aufgabe der Erfindung ist es deshalb, die Verwendung van Gummiabfällen aus Altreifen im Bauwesen durch genaue Konstruktionsangabe zu ermöglichen. Erfindungsgemäss wird die3 dadurch erreicht, dass die in der Hauptmeldung beschriebenen Platten bis zu 95 Gew % Gummianteile aus Altreifen enthalten. Bei Ausgestaltung mit anorganischen Stoffen, wie Zement,Gips und dgl., sollen verzugsweise ca 30 Gew % Gummianteile nicht überschritten werden. Andere organ. Abfälle z.B.The object of the invention is therefore the use of rubber waste from used tires in the construction industry through precise design information. According to the invention die3 is achieved in that the plates described in the main message to Contains 95% by weight of rubber from old tires. When designing with inorganic Materials such as cement, plaster of paris and the like should preferably be about 30% by weight of rubber not be exceeded. Other organ. Waste e.g.

Textilfasern, Kunststoffe, die bei der Aufbereitung abfallen, können bei der herstellung der Platten mit einbezogen werden und bewirken sogar eine Verbesserung der Eigenschaften. In einer besonderen Ausgestaltung der Erfindung werden derartige Platten, z.B. in einer Starke von 6 ca, als verlorene Schalung ausgebildet.Textile fibers, plastics that can fall off during processing are included in the production of the panels and even bring about an improvement of properties. In a particular embodiment of the invention, such Plates, e.g. 6 approx. Thick, designed as permanent formwork.

Die Erfindung soll anhand von Beispielen beschrieben werden. Die zu verwendende Platte kann enthalten: Bei einer Stärke der Platte von einen Gummiabfall der Grösse ven 30 mm 12/20 mm 40 " 20/30 " 1 " 3o/4o rt Verbessernd wirken sicn die Eigenschaften aus, je kliner die verendeten Schnitzel sind. Wünschenswert ist ogar ei Anteil an Granulat mit einer Kerngrösse von 3-5 mm in Hshe von etwa 2o Gew % der Schnitzel. Besonders vorteilhaft ist eine Deckschicht mit Granulat oder Gummimehl, wodurch eine bessere Struktur erhältlich ist. Die Hauptbetsandteile sind Zement, Kies und Sand. Diese Platten lassen sich sauber in der üblichen Weise verputzen, wobei dem Putz ebenfalls Gummianteile in Form von Granulat oder Gummimehl oder auch Glasfasern oder Kunststoffe zugesetzt weruen kann. Durch diesen Zusatz ergibt sich gegenilber dem Normalputz eine rhöhte Rissfestigkeit und Frostbeständigkeit. Weiterhin haben diese Platten den Vorteil, dass sie sehr gut nagelbar sind und auch Schrauben ohne schwierigkeit eingebracht werden können. Desgleichen können die Platten auf einfache Weise zerschnitten werden.The invention is to be described by means of examples. The too The plate to be used may contain: With a thickness of the plate of a rubber waste the size ven 30 mm 12/20 mm 40 "20/30" 1 "3o / 4o rt They have an improving effect the smarter the schnitzel that is dead, the more difficult it is. Is desirable ogar a proportion of granules with a core size of 3-5 mm in height of about 20 wt % the schnitzel. A top layer with granules or rubber powder is particularly advantageous, whereby a better structure can be obtained. The main sandblasting parts are cement, Gravel and sand. These panels can be plastered clean in the usual way, with the plaster also rubber parts in the form of granules or rubber powder or also Glass fibers or plastics can be added. This addition results in compared to normal plaster, increased crack resistance and frost resistance. Farther these plates have the advantage that they can be nailed very well, as can screws can be introduced without difficulty. Likewise, the plates can easy way to be cut up.

Platten, die aus Gummiabfällen im Gemisch mit Textilfasern und Holzfasern hergestellt werden, können bis zu 95 Gew ?o dieser Materialien enthalten und sind äusserst elastisch.Sheets made from rubber waste mixed with textile fibers and wood fibers can contain and are up to 95% of these materials extremely elastic.

In der zuerst beschriebenen Platte sollen die in den Altreifen enthaltenen und dann in den Zerkleinerungsanlagen mit anfallenden Metall und Textilanteile mit verwendet werden. Dadurch ergibt sich eine bessere Stabilität. Im Gegensatz dazu ist es wünschenswert, dass die mit Klebstoffen hergestellten Platten möglichst frei vcn derartigen Metallteilen sind, was beispielsweise über magnetische Abseneider vorgenommen werden kann. Diese Platten haben den Vorteil der Unzerbrechlichkeit sowie der Elastizttät. Ganz besonders sind die wärmeiselierenden und schalldämpfenden Eigenschaften herverzuheben. Die Eigenschaften der oben erwähnten Platten und Steine sind z.-r. verschieden, was damit zusammenhängt,dass die Bindung dr Altgummiabfälle mit verschiedenen Mittels vorgenomen wird. Zement v rhält sich anders als organischer Kleber. Das bedeutet, das eine kombinierte Platte ergänzende Eigenschaften besituzt. Die hervorragend isolierende mit Klebstoff hergestellte Platte geringerer Stabilität kombiniert mit einer zementgebundenen Platte geringerer wärme und schalldämpfender Isolation vereinigt eine Reihe von hervorragenden Eigenschaften.In the plate described first, those contained in the old tires should be and then in the shredding plants with accruing metal and textile parts be used. This results in better stability. In contrast to it is desirable that the panels made with adhesives be as free as possible Such metal parts are what, for example, magnetic filters can be made. These panels have the advantage of being unbreakable as well as the elasticity. The heat insulating and sound absorbing ones are very special Features to highlight. The properties of the above-mentioned slabs and stones are z.-r. different, which is related to the fact that the bond dr scrap rubber with different Is done by means. Cement holds up unlike organic glue. This means that a combined plate is complementary Properties possessed. The excellent insulating made with glue Slab of lower stability combined with a cement-bonded slab of lower strength thermal and sound-absorbing insulation combines a number of excellent properties.
