Abstract

Die Erfindung besteht darin, dass geschnittenes oder geraspeltes Altgummi, vorzugsweise von Autoreifen, unter Zusatz von Verfestigungsmitteln, vorzugsweise Phenolharz oder Frischgummi, bei Waermezufuhr in staehlernen Formen zu von Hand verlegbaren Tafeln in den durch die Konstruktion der Verkehrsflaechen bestimmten geometrischen Abmessungen geformt wird, die an Stelle bisheriger Fugeneinlagen eingesetzt werden.The invention consists in that sliced or shredded waste rubber, preferably of car tires, with the addition of solidifying agents, preferably phenolic resin or fresh rubber, is molded into heat-transferable shapes in the form of staves to manually laid panels in the geometrical dimensions determined by the construction of the traffic surfaces Place previous joint inserts are used.

Description

Die Erfindung besteht darin, daß aus bisher wenig verwendeten Altgummi, vorzugsweise Autoreifen, Fugeneinlagen für Verkehrsflächen aus Zementbeton gewonnen und eingesetzt werden, die vorzugsweise für die konstruktiv erforderlichen Raumund Verschiebefugen verwendet werden.The invention consists in obtaining and using joint linings for traffic surfaces made of cement concrete from scrap rubber, which has hitherto been little used, preferably car tires, which are preferably used for the constructionally required space and sliding joints.

Seit Beginn des Zementbetonstraßenbaues werden als Fugeneinlagen Holzbretter, vorzugsweise aus Weichholz, eingesetzt. Mit der Verknappung und Verteuerung dieses Rohstoffes werden hinreichend verformbare Ausweichstoffe gesucht.Since the beginning of the cement concrete road construction wooden boards, preferably made of softwood, are used as joint inlays. With the scarcity and increase in price of this raw material, sufficiently deformable substitutes are being sought.

Es wurde gefunden, daß Fugeneinlagen aus zerkleinertem Altgummi die erforderlichen Eigenschaften aufweisen und eine Kompressibilität von etwa 60% besitzen.It has been found that joint inserts made of shredded waste rubber have the required properties and have a compressibility of about 60%.

Die Erfindung ist dadurch gekennzeichnet, daß geschnittenes oder geraspeltes Altgummi von verwendungsunfähigen Gummierzeugnissen, vorzugsweise alten Autoreifen, mit Hilfe von Phenolharzen oder Frischgummi unter Wärmezufuhr in elektrisch beheizten Stahlformen zu tafelförmigen Erzeugnissen verfestigt wird, die von Hand verlegbar sind.The invention is characterized in that sliced or shredded waste rubber of unusable rubber products, preferably old car tires, by means of phenolic resins or fresh rubber with heat input in electrically heated steel molds is solidified into tabular products which can be laid by hand.

Die technische Aufgabe der Erfindung liegt darin, den technisch wertvollen Rohstoff Holz durch ein geeignetes Produkt aus Sekundärrohstoff zu ersetzen, welches übereine geeignete Formänderungsfähigkeit verfügt.The technical object of the invention is to replace the technically valuable raw material wood by a suitable product of secondary raw material, which has a suitable shape change ability.

Durch die Erfindung werden die bisher notwendigen Deponien für Altgummi entsprechend dem erreichbaren Verwendungsumfang abgebaut.By the invention, the previously necessary landfills for waste rubber are reduced according to the achievable scope of use.

Im Gegensatz zum bisher verwendeten Holz ist die neue Fugeneinlage absolut verrottungsfest.In contrast to the wood used so far, the new joint inlay is absolutely rot-proof.
