Abstract

Electromagnetic screen for rooms, comprising modules of rectangular metal sheets. The modules are flat, standard metal sheets. The metal sheets are joined to one another in an overlapping manner and screwed together. RF seals are inserted into the overlapping zones (Figure 1). <IMAGE>

Description

Beschreibung description

Die Erfindung betrifft eine elektromagnetische Abschirmung nach dem Oberbegriff des Anspruchs 1. Aus der DE-OS 31 29 582 ist eine elektromagnetisch geschirmte Kammer in Modulbauweise bekannt, mit Modulen aus rechteckigen Blechen mit abgewinkelten Kanten. Die Bleche werden an den abgewinkelten Kanten miteinander verlötet oder verschweißt. Diese Kammer ist sehr einfach und schnell aufzubauen und preisgünstig. Besonders die geschweißte Version hat jedoch den Nachteil, daß sie nach der Aufstellung nur schwer wieder demontierbar ist, und daß Schweißarbeiten in manchen Bereichen zu unerlaubten Störungen (Hitze, Gas, Lichtbogen, Funkstörungen) der Umwelt führen. The invention relates to an electromagnetic shield according to the Preamble of claim 1. From DE-OS 31 29 582 is an electromagnetic shielded chamber in modular design known, with modules made of rectangular sheets with angled edges. The sheets are joined together at the angled edges soldered or welded. This chamber is very easy and quick to assemble and inexpensive. However, the welded version in particular has the disadvantage that it is difficult to dismantle after installation, and that welding work in some areas to unauthorized interference (heat, gas, electric arc, radio interference) the environment.

Aufgabe der Erfindung ist es, eine weitere Lösung für eine Abschirmung der eingangs genannten Art anzugeben, die besonders einfach und wirtschaftlich herzustellen ist. Die Lösung dieser Aufgabe ist im Patentanspruch 1 gekennzeichnet. Die weiteren Ansprüche beinhalten vorteilhafte Ausführungen der Erfindung. The object of the invention is to provide a further solution for a shield Specify the type mentioned above, which are particularly easy and economical to manufacture is. The solution to this problem is characterized in claim 1. The others Claims contain advantageous embodiments of the invention.

Die Erfindung wird im folgenden anhand der Figuren näher erläutert. The invention is explained in more detail below with reference to the figures.

Fig. 1 zeigt einen Ausschnitt aus einer erfindungsgemäßen Abschirmung im Schnitt. Als Module werden Bleche aus zum Beispiel Aluminium, Kupfer, oder verzinktem Stahlblech in Jtandardgrößen des Metallgewerbes verwendet Die Bleche bleiben flach, sodaß nur ein minimaler Arbeitsaufwand erforderlich ist. Sie werden überlappend aneinandergefügt und verschraubt. In die Überlappungszonen sind HF-Dichtungen eingelegt. Fig. 1 shows a section of a shield according to the invention on average. Sheets made of, for example, aluminum, copper or galvanized are used as modules Steel sheet used in standard sizes in the metalworking industry The sheets remain flat, so that only a minimal amount of work is required. They become overlapping joined and screwed together. HF seals are inserted in the overlapping zones.

Die Eckmodule bestehen vorteilhafterweise aus rechtwinklig gebogenen Blechen, vergleiche Fig. 2, sodaß komplizierte Verschraubungen an den Ecken und Kanten entfallen. The corner modules are advantageously made of bent at right angles Sheet metal, compare Fig. 2, so that complicated screw connections at the corners and Edges are omitted.

Fig. 3 und 4 zeigen im Schnitt und in Draufsicht die Überlappungszonen vor vier benachbarten Blechen. Im schraffierten Bereich, Fig. 4, liegen alle vier Bleche übereinander. statt sonst immer nur zwei. In diesem Bereich kann ein Dickenausgleich mit Hilfe der HF-Dichtung geschaffen werden (zum Beispiel durch Weglassen der Dichtung zwischen den beiden mittleren Blechen). 3 and 4 show the overlap zones in section and in plan view in front of four neighboring sheets. All four are in the hatched area, FIG. 4 Sheets on top of each other. instead of always only two. A thickness compensation can be used in this area be created with the help of the HF seal (for example by omitting the seal between the two middle sheets).

Bei größeren Räumen kann es erforderlich sein, die Abschirmung auf ein Tragegerüst aufzuschrauben. In larger rooms, it may be necessary to open the shield to screw on a support frame.

Für einige Anwendungen ist es vorteilhaft, wenn schon vorbereitend an den Modulen Schrauben oder Muttern angeschweißt werden, zum Beispiel wenn Innenräume mit einem HF-Schirm ausgekleidet werden sollen. Die Montage wird dabei wesentlich erleichtert. For some applications it is advantageous if already preparatory Bolts or nuts are welded to the modules, for example in interiors should be lined with an HF shield. The assembly becomes essential relieved.

Die erfindungsgemäße Abschirmung zeichnet sich durch größte Einfachheit der Metallhaut aus. Sie ist leicht demontierbar, sodaß die Module ohne weiteres wiederverwendet werden können. The shield according to the invention is characterized by the greatest simplicity the metal skin. It is easy to dismantle so that the modules can be easily removed can be reused.
