Im folgenden werden Ausführungsbeispiele der Erfindung unter Bezugnahme auf die Zeichnung näher erläutert.In the following, exemplary embodiments of the invention are referred to explained in more detail on the drawing.

Es zeigen: Figur 1 eine Draufsicht auf die Außenseite eines aufgeklappten Segmentbogens gemäß einer Ausführungsform der Erfindung; Figur 2 einen Querschnitt in einer Ebene II-II der Figur 1 und Figur 3 eine vergrößerte, etwas schematische und teilweise auseinandergezogene Ansicht einer bevorzugten Ausführungsform des Oberflächenabschlusses für das Dämmelement gemäß der Erfindung.The figures show: FIG. 1 a plan view of the outside of an unfolded one Segment arc according to an embodiment of the invention; Figure 2 a cross section in a plane II-II of Figure 1 and Figure 3 is an enlarged, somewhat schematic and partially exploded view of a preferred embodiment of the surface finish for the insulating element according to the invention.

In Figur 1 ist ein sogenannter Segmentbogen im aufgeklappten Zustand und in Draufsicht auf die Außenseite dargestellt.In Figure 1, a so-called segment arch is in the unfolded state and shown in plan view of the outside.

Der Segmentbogen besteht in bekannter Weise aus zwei Halbschalen, die jeweils aus drei Segmenten 10a, 12a bzw. 14a und 1Ob, 12b bzw. 14b zusammengesetzt sind.The segment arch consists in a known way of two half-shells, each composed of three segments 10a, 12a or 14a and 10b, 12b or 14b are.

Figur 2 zeigt einen Querschnitt durch die mittleren Segmente 12a und 12b; gleichzeitig stellt Figur 2 einen Querschnitt durch ein gerades rohrförmiges Dämmelement zur Ummantelung eines geraden Rohrleitungsstückes dar.Figure 2 shows a cross section through the middle segments 12a and 12b; at the same time, Figure 2 shows a cross section through a straight tubular Insulating element for sheathing a straight pipe section.

Wie aus Figur 2 ersichtlich ist, enthält das Dämmelement eine rohrförmige , diametral geteilte Dämmschale, die also aus zwei Halbschalen 16a und 16b besteht. Die Dämmschale besteht aus Gründen der Feuersicherheit vorteilhafterweise aus Mineralfaser, insbesondere Glasfaser.As can be seen from Figure 2, the insulating element contains a tubular , diametrically divided insulation shell, which therefore consists of two half-shells 16a and 16b. The insulation shell is advantageously made of mineral fiber for reasons of fire safety, especially fiberglass.

Mit der Aussenseite der Halbschalen 16a und 16b ist ein folienförmiger Oberflächenabschluß oder Mantel 18 betestigt, der in Figur 3 schematisch genauer dargestellt ist. Der Mantel 18 besteht aus zwei Aluminiumfolien 20 und 22, deren Dicke vorteilhafterweise etwa 50 ßm beträgt. Die beiden Aluminiumfolien 20 und 22 bilden mit einer zwischen ihnen angeordneten und mit ihnen verbundenen lockeren Glasfaserarmierung 24 eine Schichtstruktur. Die Glasfaserarmierung 24 besteht vorzugsweise aus einem weitmaschigen, quadratischen Gitter aus multifilen Glasfaserfäden. Die Glasfaserfäden können einen Durchmesser von z.B. 25 bis 50 ßm, insbesondere 35 ßm haben. Die Maschenweite beträgt vorteilhafterweise etwa 10 mm. Das Glasfaserfadengitter kann ein offenes Gewebe mit Leinenbindung sein, wie es in Figur 3 dargestellt ist.With the outside of the half-shells 16a and 16b is a film-shaped Surface termination or jacket 18 affixed, which is shown in more detail schematically in FIG is shown. The jacket 18 consists of two aluminum foils 20 and 22, whose Thickness is advantageously about 50 µm. The two aluminum foils 20 and 22 form with a loose one arranged between them and connected to them Glass fiber reinforcement 24 has a layer structure. The fiberglass reinforcement 24 is preferably made the end a wide-meshed, square grid made of multifilament fiberglass threads. The fiberglass threads can have a diameter of e.g. 25 to 50 µm, in particular 35 µm. The mesh size is advantageously about 10 mm. The fiberglass mesh can be an open one Be fabric with plain weave, as shown in FIG.

Um eine möglichst hohe Feuersicherheit zu erreichen, sind die beiden Aluminiumfolien 20 und 22 miteinander und mit dem Glasfaserfadengitter 24 durch ein schwer entflammbares Material verbunden. Cit eignet sich auch eine dünne und damit dem Feuer kaum Nahrung gebende Schicht aus Kleber oder Lack, z.B. einem Lack auf Polyurethanbasis.In order to achieve the highest possible fire safety, the two are Aluminum foils 20 and 22 with each other and with the fiberglass mesh 24 through a flame-retardant material connected. Cit is also suitable a thin and So that the fire is hardly nourished by a layer of glue or varnish, e.g. a varnish based on polyurethane.

Die Glasfaserfäden der Glasfaserarmierung 24 sind nicht brennbar und außerdem können sie mehrfach gebogen werden, ohne zu brechen. Der aus der Schichtstruktur bestehende, mit der Außenseite der Dämmschale 16 verbundene Mantel bildet also ein stabiles Scharnier 26 zwischen den beiden Halbschalen 16a und 16b (Figur 2), so daß die Halbschalen mehrmals auf- und zusammengeklappt werden können, ohne daß der Mantel an der Knickstelle reißt.The fiberglass threads of the fiberglass reinforcement 24 are not flammable and they can also be bent several times without breaking. The one from the layer structure existing jacket connected to the outside of the insulating shell 16 thus forms a stable hinge 26 between the two half-shells 16a and 16b (Figure 2), see above that the half-shells can be opened and folded several times without the Coat tears at the kink.

Bei Verwendung von Steinwolle, Glasfasern, Asbestgewebe oder -vlies und dgl. als Material für die Dämmschale und dem anhand von Figur 3 beschriebenen Schichtstruktur-Mantel ist das Dämmelement gemäß der Erfindung nicht brennbar und genügt daher den höchsten Anforderungen an die Feuersicherheit.When using rock wool, glass fibers, asbestos fabric or fleece and the like.
