Gegenstand der Erfindung ist ein Element zur Errichtung von gegen elektromagnetische Störungen abgeschirmten Räumen.The invention relates to an element for the construction of rooms shielded against electromagnetic interference.
Um eine optimale Bodennutzung zu gewährleisten, werden heute vorzugsweise Hochbauten errichtet. In solchen modernen Großbauten, wie z. B. Krankenhäusern, Rechenzentren usw. kommt es aus räumlichen Gründen zwangsläufig zu einer unmittelbaren Nachbarschaft von Energieversoigungsanlagen und elektronischen Geräten bzw. Rechenanlagen. Dies bedeutet, daß mit dem Zusammenwirken vieler Funktionen in einem eng umgrenzten Bauwerk auch die hiefür notwendigen energietechnischen Komponenten, besonders die elektrische Energieversorgung in hochkonzentrierter Form vorhanden sind. Dabei werden einerseits immer größere Energiemengen bereitgestellt und umgesetzt, anderseits sollen mechanische Feinstmeßgeräte und höchstempfindliche elektronische Einrichtungen, wie sie Regelungs- und Steuerungstechnik, Medizintechnik, Meßtechnik u. ä. heute kennen, klaglos funktionieren. Diese Forderungen sind a priori widersprüchlich. Diesbezüglich auftretende Schwierigkeiten bedingen die Durchführung von Abschirmungsmaßnahmen - die Schirmung von Räumen bzw. Teilbereichen, die Erdung von Rohrleitungen, Geländern und ausgedehnten Metallteilen -.In order to ensure optimal use of the land, high-rise buildings are preferably erected today. In such modern large buildings, such as. B. hospitals, data centers, etc., for spatial reasons, there is inevitably a direct vicinity of power supply systems and electronic devices or computer systems. This means that with the interaction of many functions in a narrowly defined building, the necessary energy technology components, especially the electrical energy supply, are also available in a highly concentrated form. On the one hand, ever larger amounts of energy are made available and implemented, on the other hand, mechanical precision measuring instruments and highly sensitive electronic devices such as regulating and control technology, medical technology, measuring technology and the like. know today, function without complaint. These demands are contradictory a priori. Difficulties arising in this regard require the implementation of shielding measures - the shielding of rooms or partial areas, the grounding of pipelines, railings and extensive metal parts -.
Wenn auch zur Dämpfung störender mechanischer Schwingungen Vorkehrungen getroffen werden sollen, sind dafür geeignete schwingungsdämpfende Verbundelemente im Stand der Technik bekannt, etwa aus der EP 0 027 945, der AT-PS 232.694 sowie der DE-OS 27 52 095. Diese weisen in der Regel eine, an oder zwischen versteifenden Deckschichten angeordnete, aus spezifischen thermoplastischen Materialien verfertigte und/oder mit zahlreichen Hohlräumen versehene Kemschichten auf, die das Auftreten von Transversal- oder Scherwellen begünstigen und somit die Schwingungsenergie durch Scherung der Kemschicht vernichten oder aber die Scherkomponente der zu dämpfenden Biegeschwingung verstärkt auf eine weitere schwingungsdämpfende Schicht übertragen. Die Deckschichten) kann (können) aus Metall bestehen, das jedoch hinsichtlich optimaler Werte des Elastizitätsmoduls auszuwählen istIf precautions are also to be taken to dampen interfering mechanical vibrations, suitable vibration-damping composite elements are known in the prior art, for example from EP 0 027 945, AT-PS 232.694 and DE-OS 27 52 095. These generally have a core layer arranged on or between stiffening cover layers, made of specific thermoplastic materials and / or provided with numerous cavities, which favor the occurrence of transverse or shear waves and thus destroy the vibrational energy by shearing the core layer or else the shear component of the bending vibration to be damped increasingly transferred to another vibration-damping layer. The cover layers) can be made of metal, which, however, must be selected with regard to optimal values of the elastic modulus
Die Anforderungen an Feinstmeßräume, z. B. für Elektronenmikroskope liegen bei einer maximalen Induktion von 0,5 μΤ bis 1 μΤ bei Frequenzen um 50 Hz. Die Dämpfung von Gittern nimmt mit wachsender Frequenz ab, da die Querimpedanz elektrisch unendlich gut leitender Gitter rein induktiv ist. Im Gegensatz dazu ist bei homogenen Schirmen mit einer Schichtdicke wesentlich kleiner als die Wellenlänge die Dämpfung bis zu sehr hohen Frequenzen konstant. Es sind also homogene Schirme den Abschirmgittem vorzuziehen.The requirements for precision measuring rooms, e.g. B. for electron microscopes are at a maximum induction of 0.5 μΤ to 1 μΤ at frequencies around 50 Hz. The attenuation of gratings decreases with increasing frequency, since the cross-impedance of electrically infinitely conductive grids is purely inductive. In contrast, with homogeneous umbrellas with a layer thickness much smaller than the wavelength, the attenuation is constant up to very high frequencies. Homogeneous shields are therefore preferable to the shielding grids.
Zur Schaffung elektromagnetisch abgeschirmter Räume war es eine Methode der Wahl, vorzugsweise ca. 0,1 mm dicke Kupferfolie wie eine Tapete auf die mit glatter Oberfläche hergestellte Wand aufzubringen. Wegen des relativ hohen Gewichtes der metallischen Folie ist dazu ein geruchsintensiver Spezialkleber zu verwenden, der eine unangenehme Geruchsbelästigung für die Monteure verursachte. Wegen der relativen Steifheit der Metallfolie und der deshalb nach dem Aufkleben erforderlichen Glättungsaibeit war der Arbeitsaufwand relativ hoch. An den überlappend angeordneten Stoßkanten waren die Folien zu verlöten. Bei der Verlötung der Folien und noch mehr bei der neuerdings bevorzugten Verschweißung mittels Kupferdrahtes in einem Schutzgasverfahren, durch die Inhomogenitäten im Schirmwiderstand vermeidbar sind und daher eine bessere Störstromableitung erzielbar ist, kann es durch lokale Überhitzungen zu einer störenden Aufblähung der Kleberschicht kommen.To create electromagnetically shielded rooms, it was a method of choice to apply approximately 0.1 mm thick copper foil like wallpaper to the wall made with a smooth surface. Due to the relatively high weight of the metallic foil, an odor-intensive special adhesive must be used, which caused an unpleasant smell for the fitters. Because of the relative stiffness of the metal foil and the smoothing required after gluing, the work involved was relatively high. The foils had to be soldered to the overlapping edges. When the foils are soldered and even more so with the recently preferred welding using copper wire in a shielding gas process, by means of which inhomogeneities in the shield resistance can be avoided and therefore better interference current dissipation can be achieved, local overheating can lead to a disruptive bloating of the adhesive layer.
Aufgabe der Erfindung war es daher, ein Element zu schaffen, um im Einklang mit der heute bevorzugt angewandten Trockenbauweise für den Innenausbau eine vereinfachte Herstellung von mit Kupferfolie geschirmten Räumen zu ermöglichen und sie löst diese Aufgabe dadurch, daß das Element aus einem Trägerelement in Form einer Leichtbauplatte vorzugsweise einer an sich bekannten Gipskartonplatte mit einer auf einer Fläche aufkaschierten Kupferfolie besteht, daß die Kupferfolie aus Elektrolytkupfer hoher Leitfähigkeit besteht, daß die Kupferfolie die eine Fläche der Leichtbauplatte zur Gänze bedeckt und an mindestens zwei aneinander stoßenden Kanten der Leichtbauplatte über diese Kanten hinausragt.The object of the invention was therefore to provide an element in order to enable a simplified production of rooms shielded with copper foil in accordance with the dry construction method which is preferred today for interior construction, and it achieves this object in that the element consists of a carrier element in the form of a Lightweight construction board, preferably a gypsum board known per se, with a copper foil laminated on one surface, that the copper foil consists of electrolytic copper of high conductivity, that the copper film completely covers one surface of the lightweight construction board and protrudes beyond these edges on at least two abutting edges of the lightweight construction board.
Die mit dem erfindungsgemäßen Element erzielbaren Vorteile liegen darin, daß durch seine Verwendung sehr rasch nach Art der heute verbreiteten Trockenputztechnik, geschirmte Räume mit glatten Sichtflächen hergestellt werden können, daß dabei jegliche mit unangenehmer Geruchsbildung bzw. gesundheitschädigender Einwirkung verknüpfte Klebearbeiten vor Ort entfallen können, daß durch die spezielle Anordnung der Vorstöße der Kupferfolie eine senkrechte Stapelbarkeit der Elemente ohne Beschädigung der Kupferfolie möglich ist, ebenso eine leichte Transportierbarkeit durch Anfassen der beiden Kanten, an denen die Kupferfolie bündig abschließt. Nach einer vorteilhaften Ausführungsform kann die Verbindung der Kupferfolie mit der Fläche der Leichtbauplatte im Randbereich der Leichtbauplatte ausgespart sein. Dadurch wird mit Sicherheit vermieden, daß bei der Herstellung der nahtlosen Schirmung durch Verlötung oder die neuerdings vorgezogene Verschweißung der Randbereiche der Folie durch lokale Überhitzung eine störende Aufwerfung der Kupferfolie durch Blasenbildung eines Klebestoffes auftritt.The advantages that can be achieved with the element according to the invention are that, through its use, very quickly in accordance with the type of dry cleaning technique that is common today, shielded rooms with smooth visible surfaces can be produced, so that any adhesive work associated with unpleasant odor or harmful effects can be omitted on site Due to the special arrangement of the advances of the copper foil, the elements can be stacked vertically without damaging the copper foil, as is easy transportability by touching the two edges at which the copper foil is flush. According to an advantageous embodiment, the connection of the copper foil to the surface of the lightweight building board can be left out in the edge region of the lightweight building board. It is thereby avoided with certainty that in the manufacture of the seamless shielding by soldering or the recently preferred welding of the edge regions of the foil by local overheating, a disturbing throwing up of the copper foil by blistering of an adhesive occurs.
