Abstract

Plastic material for prodn. of covers, joints, seals etc. e.g. in buildings, by shrinking under the influence of temp. changes is associated with a device for temp. transfer and distribution. The device allows accurate heating of the plastic material, thus avoiding damage to the material, and more accurate placing in position. Use of gas flames and hot air blowers avoided. Specif. the device consists of a conductor, esp. a metal conductor, which is embedded in or surrounds the plastic material, and increases the mechanical stability of the plastic material.

Description

Kunststoffmaterial, welches bei Temperaturänderung schrumpft. Plastic material that shrinks when the temperature changes.

Die Erfindung betrifft ein Kunststoffmaterial, welches zur Herbeiführung seiner Funktion, beispielsweise als Ummantelung, Dichtung oder Verbindung von Teilen, erwärmt wird und hierdurch schrumpft.The invention relates to a plastic material which is used to induce its function, for example as a casing, seal or connection of parts, is heated and thereby shrinks.

Bekannt sind Schrumpfschlauche, Schrumpfmanschetten oder Schrumpfforalinge aus Kunststoff, die mittels einer Flamme (z.B. Gasflamme) oder mittels Heissluft (z.B. Föhn) erwärmt werden und dadurch in gewünschter Weise auf die betreffenden Teile dicht und/oder fest aufschrumpfen. Der Nachteil dieser Methode liegt darin, dass die Montageorte für derartige Arbeiten meistens Baustellen (Wohn- und Fabirkrohbauten) oder im bau befindliche Umspannwerke, Trafostationen etc. sind, an denen kein Gas oder Strom zur Verfügung steht.Shrink tubes, shrink sleeves or shrink troalings are known made of plastic, which is produced by means of a flame (e.g. gas flame) or hot air (e.g. hair dryer) and thus in the desired manner on the relevant Shrink parts tightly and / or firmly. The disadvantage of this method is that that the assembly locations for such work are mostly construction sites (residential and factory shells) or substations, transformer stations, etc. under construction that do not have gas or electricity is available.

Es wird somit vorausgesetzt, dass der Monteur, um die Schrumpfungen durchführen zu können, eine Gasflasche mit Brenner bei sich führen muse oder einen heissluft-Föhn, für dessen Betätigung er in aufwendiger Weise von oft weither über Verlängerunskabel Strom beschaffen muss.It is thus assumed that the fitter to remove the shrinkage to be able to carry a gas cylinder with a burner with you or a muse hot air hair dryer, for the operation of which he is often from far and wide in an elaborate manner Extension cable must procure electricity.

Bei der Verwendung einer offenen Flamme besteht die Gefahr der Beschädigung der Wanddurchführung von Schaltkästen oder dergl.There is a risk of damage when using an open flame the wall duct of switch boxes or the like.

Die Aufgabe der Erfindung ist es, diese Mängel und Nachteile zu beseitigen.The object of the invention is to eliminate these shortcomings and disadvantages.

Die Lösung de Aufgabe ist den P a t e n t a n s p r ü c h e n zu entnehmen.The solution to the problem can be found in the p a t e n t a n t r ü c h e n.

Es sind zahlreiche Ausführungsformen zur Verwirklichung der Erfindung möglich. die Erfindung ist nicht auf die besch@iebenen Ausführungsbeispiele beschrünkt, sondern umfasst alle nach den P a t e n t a n s p r ü c h e n denkbaren Möglichkeiten.There are numerous embodiments for practicing the invention possible. the invention is not limited to the exemplary embodiments described, but includes all possible possibilities according to the P a t e n t a n s p r ü c h e n.

Bei einem Ausführungsbeispiel wird bei der Nerstellung des Schrumpfformlings in das Kunststoffmaterial eine Drahtkonstruktion aus besonders gut wärmeleitfühigem Metall eingebettet. Diese ist nach Art eines Scherengitters, spiralenförmig oder einer anderen Zweckform zur Anpassung an die beim Schrumpfvorgang eintretende Durchmesseränderung ausgebildet, Vorzugsweise mehrere Enden dieser Drahtkonstruktion werden mit einer oder mehreren Wärmequellen wie einem gut brennenden Ester, flartspiritus oder dergl. verbuiden. Nach Abschluss der Montage wird der wärmeerzeugende Stoff angezündet. Die erwärmte Drahtkonstruktion bewirkt die Schrumpfung des Kunststoffmaterials und bildet zusammen mit diesem die Ummantelung, Dichtung oder die Verbindung von Teilen.In one embodiment, when the shrink molding is produced in the plastic material a wire construction made of particularly good heat-conducting material Metal embedded. This is like a concertina gate, spiral or another form of purpose for adapting to the change in diameter occurring during the shrinking process Preferably several ends of this wire construction are made with one or several heat sources such as a well-burning ester, flartspiritus or the like verbuiden. After the assembly is completed, the heat-generating material is set on fire. The heated wire construction causes the plastic material to shrink and forms together with this the casing, seal or the connection of parts.

Bei einem anderen Ausführungsbeispiel wird die Metallkontruktion an der Oberfläche des Kunststoffmaterials angeordnet. Ausser der Erhöhung der mechanischen Stabilität wird dadurch ein ausgezeichneter Oberflächenschutz gegen mechanische Beschädigungen erzielt.In another embodiment, the metal construction is on arranged on the surface of the plastic material. Except for increasing the mechanical This makes stability an excellent surface protection against mechanical Damage achieved.

Bei einer weiteren Äusftihrung wird für die Drahtkonstruktion ein Widerstandsdralit verwendet welcher sich mit einer elektrichen Stromquelle verbunden erwärmt und die Schrumpfung des Kunststoffmaterials bewirkt.In another case, a wire construction will be used Resistive wire used which connects to an electrical power source heated and causes the shrinkage of the plastic material.
