Description
Die Erfindung betrifft eine demontierbare und wieder montierbare Wärmedämmung, insbesondere für nukleare Anlagen, bestehend aus einzelnen Wärmedämmelementen, die mit jeweils benachbarten Wärmedämmelementen mittels eines Flachstahlrahmens unmittelbar zusammengebaut sind und deren Wärmedämm-Material mit einer metallischen Umhüllung staubdicht umgeben ist.The invention relates to a removable and remountable thermal insulation, especially for nuclear Systems consisting of individual thermal insulation elements directly with adjacent thermal insulation elements by means of a flat steel frame are assembled and their thermal insulation material is dustproof with a metallic casing is surrounded.
Ein zum Aufbau einer solchen Wärmedämmung verwendetes Wärmedämmelement ist offenkundig vorbenutzt und besteht aus einem starren, mit Wärmedämm-Material gefüllten Hohlkörper aus Biech. der auf einer Seite mit einem Flachstahlrahmen versehen ist.A thermal insulation element used to build up such thermal insulation is evident previously used and consists of a rigid hollow body made of Biech, filled with thermal insulation material. which is provided with a flat steel frame on one side.
Bei einem solchen Wärmedämmelement können wegen der starren Wände der Wärmedämmschicht Verformungen infolge Temperatureinwirkung nicht aufgenommen werden, so daß es zur Spaltenbildung zwischen den einzelnen Wärmedämmelementen bzw. zum Verklemmen derselben untereinander kommen kann.In such a thermal insulation element, because of the rigid walls of the thermal insulation layer Deformations as a result of the action of temperature are not absorbed, so that gaps are formed come between the individual thermal insulation elements or to jam them together can.
Aufgabe der Erfindung ist es. die Wärmedämmung der eingangs genannten Art so auszubilden, daß diese Spaltenbildung zwischen den einzelnen Wärmedämmelementen bzw. ein Verklemmen derselben untereinander verhindert wird.It is the object of the invention. to train the insulation of the type mentioned so that this Formation of gaps between the individual thermal insulation elements or jamming of the same with one another is prevented.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst. daß jedes Wärmedämmelement aus einer Metallkassette und einer kissenartig ausgebildeten Wärmedämmschicht besteht, die an der Rückseite der Metallkassette befestigt ist, daß die Wärmedämmschicht von einem mit einer Metallfolie umhüllten Wärmedämm-Maierial gebildet ist und daß die Seitenwände der Kassette den Flaehstahlrahmen bilden.This object is achieved according to the invention. that each thermal insulation element from a metal cassette and a cushion-like thermal insulation layer, which is on the back of the metal cassette is attached that the thermal barrier coating of one with a metal foil covered thermal insulation maierial is formed and that the side walls of the cassette form the Flaehstahlrahmen.
Die kissenartige Ausbildung der Wärmedämmschicht ermöglicht die Aufnahme der infolge der Temperatureinwirkung auftretenden Verformungen. Durch die Ausbildung des Flachstahlrahmens als Teil einer Metallkassette ist für das nur von einer Metallfolie umhüllte Wärmedämm-Material auf seiner der Objektwand abgewandten Seite ein ausreichender Oberflächenschutz vorhanden.The cushion-like design of the thermal insulation layer enables the absorption of the temperature effects occurring deformations. By forming the flat steel frame as part of a The metal cassette is for the thermal insulation material on the object wall, which is only covered by a metal foil there is sufficient surface protection on the opposite side.
Von besonderem Vorteil ist die erfindungsgemäße Wärmedämmung deshalb, weil sie sich hervorragend für den Einsatz in nuklearen Anlagen eignet. In solchen Anlagen werden an Wärmedämmelemente und die daraus zu erstellenden Wärmedämmungen besondere Anforderungen gestellt. Die Wärmedämmung muß bis zu hohen Temperaturen temperaturbeständig sein und muß insbesondere staubfrei abdichten. Sie darf nicht aus Materialien bestehen, die bei Abrieb Staub absondern, der als solcher bereits gesundheitsschädlich sein kann, in nuklearen Anlagen aber darüber hinaus noch nuklear verseucht wäre. Dies gilt insbesondere dann, wenn die Umhüllung statt aus einer Metallfolie, wie beim Gegenstand der Erfindung, aus einem Gewebe, insbesondere aus einem Asbestgewebe besteht Die Zeichnungen zeigen inThe thermal insulation according to the invention is particularly advantageous because it is excellent for suitable for use in nuclear plants. In such systems, thermal insulation elements and the The thermal insulation to be created from it has special requirements. The thermal insulation must be up to be temperature resistant to high temperatures and must in particular seal dust-free. You mustn't go out There are materials that, when rubbed, emit dust, which as such can already be harmful to health nuclear facilities but would also be nuclear contaminated. This is especially true if the Wrapping instead of a metal foil, as in the subject matter of the invention, made of a fabric, consists in particular of an asbestos fabric. The drawings show in

F i g. 2 und 3 zwei einzelne Elemente ebenfalls in der Perspektive;F i g. 2 and 3 two individual elements also in perspective;
F i g. 2a und 3a zwei Seitenansichten der Elemente nach F i g. 2 und 3.F i g. 2a and 3a are two side views of the elements according to FIG. 2 and 3.
Die Erfindung besteht im wesentlichen aus einzelnen vorgefertigten Dämmelementen 1, aus umhülltem Wärmedämm-Material 3 und einer Metallkassette 2. Die Elemente können entsprechend der Form des Antagenteiles gestaltet und geforn·,. sein. Die Kassetten können zusätzlich mit einem stabilen Flachstahlrahmen 2b verstärkt sein, der entsprechende Flanschbohrungen 2c zur gegenseitigen Befestigung aufweist. Ebenso ist vorgesehen, die Wärmedämmung 3 als Teil für sich über eine Spannfederverbindung 5 und Haken 5a mit der Kassette 2 zu befestigen. In der Wärmedämmung 3 können gegebenenfalls mehrere Distanzhalterungen 6 vorgesehen sein, die auf der Objektwand 9 anliegen und einen Wärmedehnungsausgleich 6a aufweisen. Die Metallkasseite 2 kann, gemäß Fig. 3a. mit den Distanzhalterungen 6 über die Befestigungsbolzen 6b verbunden sein. Zur gegenseitigen Abdichtung der Kassette 2 ist zwischen den Seitenwänden 2b' eine Dichtung 7 vorgesehen, die vorzugsweise in bekannter Weise aufgebracht sein kann. Die Befestigung der einzelnen Kassetten kann in jeder beliebig lösbaren Weise erfolgen, vorzugsweise ist jedoch an eine Schraubverbindung 8 gedacht. Abschließend sei noch erwähnt, daß der Erfindungssegenstand mit jeder konventionellen Wärmedämmung kombiniert werden kann und daß selbstverständlich der Einsatz auch bei Kälteanlagen stattfinden kann.The invention consists essentially of individual prefabricated insulating elements 1, of wrapped thermal insulation material 3 and a metal cassette 2. The elements can be designed and shaped in accordance with the shape of the antagonist part. be. The cassettes can additionally be reinforced with a stable flat steel frame 2b , which has corresponding flange bores 2c for mutual fastening. Provision is also made for the thermal insulation 3 to be fastened to the cassette 2 as a part by itself via a tension spring connection 5 and hooks 5a. In the thermal insulation 3, several spacer brackets 6 can optionally be provided, which rest on the object wall 9 and have a thermal expansion compensation 6a. The metal cash register side 2 can, according to FIG. 3a. be connected to the spacer brackets 6 via the fastening bolts 6b . For mutual sealing of the cassette 2, a seal 7 is provided between the side walls 2b ', which seal can preferably be applied in a known manner. The individual cassettes can be fastened in any detachable manner, but a screw connection 8 is preferred. Finally, it should be mentioned that the subject of the invention can be combined with any conventional thermal insulation and that it can of course also be used in refrigeration systems.
