Isolierhüllen aus Schaumstoff werden insbesondere Isolationszwecke gegen Kälte oder Wärme, z.B. für die gesamte Sanitärinstallation wie Heißwasser-, Kaltwasser-, Abwasser-Foam insulation sleeves are used in particular for insulation purposes against cold or heat, e.g. for the entire sanitary installation such as hot water, cold water, sewage
20Heizungsleitungen usw. verwendet. Des weiteren werden solche Isolierhüllen auch für Polsterungszwecke eingesetzt, beispielsweise als Schutz gegen Erdreich, bei Wanddurchführungen, zum Bewegungsausgieich von ggf. bereits isolierten Rohrleitungen, Kabeln etc. Solche Isolierhüllen vorzugsweise in rohrförmiger Gestalt können entweder direkt extrudiert werden oder aus vorgefertigten Schaumstoffbahnen hergestellt werden. Verfahren dieser Art sind beispielsweis20 heating pipes etc. used. Furthermore will Such insulating sleeves are also used for upholstery purposes, for example as protection against the ground, for wall penetrations, for movement compensation of possibly already isolated Pipelines, cables, etc. Such insulating sheaths, preferably in a tubular shape, can either directly be extruded or made from prefabricated foam sheets. Methods of this type are for example
in der DE-OS 19 15 768 oder DE-OS 25 32 406 beschrieben. Das Herstellen von Isolierhüllen insbesondere für Rohre mit großen Dicken materialsparend und guter Paßform ist z.B. in der DE-OS 29 51 660 beschrieben, bei der an der Innenseite der Isolierhülle parallel zur Längsachse des Rohres verlaufende Rippen ausgebildet sind. Hierbei hat sich jedoch als nachteilig erwiesen, daß die zwischen den Stegen nach der Verformung zum Rohrquerschnitt verbleibenden Hohlräume den Isolationswert der gesamten Isolierhülle noch erheblich erniedrigen, so daß die gewünschte Funktion beeinträchtigt wird.in DE-OS 19 15 768 or DE-OS 25 32 406 described. The manufacture of insulating sleeves, especially for pipes with large thicknesses, material-saving and a good fit is described, for example, in DE-OS 29 51 660, in which at the Ribs running parallel to the longitudinal axis of the pipe are formed on the inside of the insulating sleeve. Here has However, it has been found to be disadvantageous that the remaining between the webs after the deformation to the pipe cross-section Cavities significantly lower the insulation value of the entire insulating sleeve, so that the desired function is affected.
Der Neuerung liegt die Aufgabe zugrunde, dickwandige Isolierhüllen materialsparend mit verbesserter Isolieröl 5 wirkung und ausreichender Stabilität zu schaffen. Gemäß der Neuerung wird die gestellte Aufgabe durch eine Isolierhülle gelöst, die aus mehreren miteinander ggf. vollflächig verbundenen Schaumstoffbahnen besteht, wobei die die äußere Schicht bildende Schaumstoffbahn eine höhere Raumdichte als die die inneren Schichten bildenden Schaumstoffbahnen aufweist und die Rippen durch wellenförmige Profilierung im Bereich der Schaumstoffbahnen mit der niedrigeren Raumdichte gebildet sind.The innovation is based on the task of making thick-walled insulating sleeves material-saving with improved insulating oil 5 effect and sufficient stability. According to the innovation, the task is given by an insulating cover solved, which consists of several mutually possibly full-surface connected foam webs, the the The foam sheet forming the outer layer has a higher density than the foam sheets forming the inner layers has and the ribs by wave-shaped profiling in the area of the foam sheets with the lower Spatial density are formed.
Der neuerungsgemäß vorgeschlagenen mehrschichtige Aufbau aus Schaumstoffen unterschiedlicher Raumdichte bewirkt, daß die äußere Schicht mit hoher Raumdichte genügende Stabilität und Steifigkeit vermittelt und als eine Art Druckverteilerplatte wirkt, während die inneren Schichten mit der niedrigeren Raumdichte die Leichtgewichtigkeit, di< elastische Iblsterung und Isolierwirkung gewährlexsten und zudem eine bessere Verformung zum Rohrquerschnitt ermöglichen. Durch die wellenförmige Profilierung der Innenseite wird einerseits. Material gespart, zum anderen jedoch das Anpassen der Isolierhülle an unterschiedliche Rohrdurchmesser ermöglicht, da die wellenförmigen Rippen sichThe multilayer structure of foams of different spatial densities proposed according to the invention has the effect of that the outer layer with high density provides sufficient stability and rigidity and as a kind Pressure distribution plate works, while the inner layers with the lower bulk density are responsible for the light weight, di < elastic Iblsterung and insulating effect and also enable a better deformation to the pipe cross-section. Due to the undulating profile of the inside, on the one hand. Material saved, but on the other hand the adaptation of the insulating sleeve to different pipe diameters allows, since the wave-shaped ribs
^ ,je nach Rohrdurchmesser durch entsprechende flächige Berührung anpassen.^, depending on the pipe diameter by corresponding flat contact adjust.
Für alle diejenigen Fälle, in denen die neuerungsgemäßen Isolierhüllen als zusätzliche Polsterung bzw. Schutz gegen äußere Einwirkungen auf die umhüllte Rohrleitung dienen, kann es zweckmäßig sein, gemäß einem weiteren Vorschlag der Neuerung das Eindringen von Wasser, Feuchtigkeit, Verschmutzung o.dgl. insbesondere an den Stirnflächen der Isolierhülle dadurch zu vermeiden, daß die Isolierhülle außenseitig mit einer weiteren insbesondere schrumpfbaren Kunststoffolie umwickelt bzw. umhüllt ist. Durch Behandlung mit einer Gasflamme kann zu jedem beliebigen Zeitpunkt das Aufschrumpfen der KunststofüLie, beispielsweise einer PoIy-Ethylenfolie auf die Isolierhülle bewirkt werden. Eine nur aufgewickelte Kunststoffolie kann mit einem Bindedraht·, Klebeband o.dgl. fixiert werden.For all those cases in which the Insulating covers serve as additional padding or protection against external influences on the covered pipeline, it may be useful, according to a further suggestion of the innovation, the penetration of water, moisture, pollution or the like. in particular to avoid at the end faces of the insulating sleeve that the insulating sleeve is wrapped or enveloped on the outside with a further, in particular, shrinkable plastic film. Through treatment a gas flame can be used to shrink the plastic, for example a poly-ethylene film, at any point in time be effected on the insulating sleeve. A plastic film that has only been wound up can be tied with a binding wire, Tape or the like. be fixed.
Die Neuerung ist in der Zeichnung an einem Ausführungcbeispiel dargestellt und wird anhand dessen näher erläutert.The innovation is shown in the drawing in an exemplary embodiment and is explained in more detail on the basis of this.

Which can already be insulated or a multi-layered one may have a structure not shown in detail, additionally with the innovation according to the invention shown here schematically Insulating sleeve 2 provided. The insulating sleeve 2 is preferably made of closed-cell soft foam, such as, for example cross-linked polyol ef made in foam. TJm to provide thick-walled insulating sleeves 2 as possible, which at different pipe cross-sections 1 can be adapted,
wird die Isolierhülle 2 auf der Innenseite mit einer wellenförmigen Profilierung 4- versehen. Hierbei entstehen Rippen 21, die auf der Kopfseite abgerundet sind und wobei die Übergänge von einer Rippe zu der anderen ebenfalls abgerundet ausgebildet sind. Derartig gestaltete Isolierhüllen passen sich leicht an unterschiedlich Rohrquerschnitte an, wobei sie entsprechend im Bereich der Oberfläche des Rohres 1 aufliegen und die Rippen untereinander längs der Fläche 3 Berührung finden. Lediglich die Hohlräume 7 und 8, die je nach Durchmesser des Rohres 1 unterschiedlich groß sind, verbleiben. Die Isolierhülle 2 kann beispielsweise aus einem ebenen Zuschnitt um das Rohr 1 gewickelt werden und beispielsweise mittels eines Klebebandes zusammengehalten werden.the insulating sleeve 2 is provided on the inside with a wave-shaped profile 4-. This creates ribs 21 which are rounded on the head side and the transitions from one rib to the other are also rounded. Insulating sheaths designed in this way easily adapt to different pipe cross-sections, whereby they correspondingly rest in the area of the surface of the pipe 1 and the ribs come into contact with one another along the surface 3. Only the cavities 7 and 8, which are of different sizes depending on the diameter of the tube 1, remain. The insulating sleeve 2 can be wrapped around the pipe 1 from a flat blank, for example, and held together, for example, by means of an adhesive tape.
In der Figur 2 ist dargestellt, wie Isolierhülle 2 aus einem mehrschichtigen Sandwich-Aufbau von Schaumstoffbahnen 2a bis 2e hergestellt werden kann. Beispielsweise sind für die beiden äußeren Schichten 2a und 2e vernetzte Polyolefinschaumstoffbahnen einer Raumdichte von 150 bis 200 kg/nr mit einer Dicke von 10 mm vorgesehen, während für die inneren Schichten 2e bis 2d Schaumstoffbahnen aus vernetzten Polyolefinschaumstoffen mit einer Raumdichte von 30 kg/nr mit einer Dicke bis zu 20 mm vorgesehen sein können. Alle Bahnen 2a bis 2e können beispielsweise durch Flammkaschieren vollflächig miteinander verbunden sein. Mittels eines elektrisch beheizten Widerstanddrahtes, der die wellenförmige Profilierung 4- aufweist, kann dann der Trennschnitt 4-erfolgen, so daß, wie dargestellt, zwei Isolierhüllen aus dem gezeigten Sandwich-Aufbau hergestellt werden können.In the figure 2 it is shown how insulating sleeve 2 made of a multilayer sandwich structure of foam webs 2a to 2e can be produced. For example, 2a and 2e are crosslinked for the two outer layers Polyolefin foam sheets with a density of 150 to 200 kg / nr and a thickness of 10 mm are provided, while for the inner layers 2e to 2d foam sheets made of crosslinked polyolefin foams with a bulk density of 30 kg / nr with a thickness of up to 20 mm can be provided. All of the webs 2a to 2e can be applied over the entire surface, for example by flame lamination be connected to each other. By means of an electrically heated resistance wire that forms the wave-shaped Profiling 4-, the separating cut 4-can then be made, so that, as shown, two insulating sleeves are made from the sandwich structure shown can.
