Abstract

An electromagnetically screened chamber of modular construction and consisting of prefabricated rectangular metal plates having bent edges which are soldered or welded to one another. The metal plates are bent at right angles at the edges of the chamber.

Description

Elektromagnetisch geschirmte KammerElectromagnetically shielded chamber

Die Erfindung betrifft eineelektromagnetisch geschirmte Kaninier in Modulbauweise, wie sie aus der DE-OS 31 29 582 bekannt ist. Zum Aufbau dieser bekannten Kammer werden aus vorzugsweise ferromagnetischem Material, z. B. Stahlblech von 1 mm Stärke, rechteckige Bleche mit abgewinkelten Kanten gefertigt. Die Fläche dieser Module kann z. B.The invention relates to an electromagnetically shielded rabbit in Modular construction, as it is known from DE-OS 31 29 582. To build this well-known Chamber are preferably made of ferromagnetic material, e.g. B. sheet steel from 1 mm thick, rectangular sheets made with angled edges. The area of this Module can e.g. B.

150 x 150 cm betragen. Die Bleche werden an den Kanten miteinander verlötet oder verschweißt. Eine besonders leichte Montage ergibt sich bei halbautomatischem Punktschweißen, wobei der Punktabstand die Qualität der HR-Dichtigkeit bestimmt.150 x 150 cm. The sheets are joined together at the edges soldered or welded. A particularly easy assembly results with the semi-automatic Spot welding, where the point spacing determines the quality of the HR tightness.

Aufgabe der Erfindung ist es, eine Kammer der eingangs genannten Art anzugeben, bei welcher weniger Schweißnähte bzw. Lötungen erforderlich sind. Die Lösung dieser Aufgabe ist im Patentanspruch 1 gekennzeichnet. Der Unteranspruch beschreibt eine Weiterbildung der Erfindung.The object of the invention is to provide a chamber of the type mentioned at the beginning indicate which fewer welds or soldering are required. the The solution to this problem is characterized in claim 1. The subclaim describes a further development of the invention.

Die Erfindung wird im folgenden anhand der Figuren näher erläutert. Die Figuren 1 und 2 zeigen Ausschnitte aus den Kanten zweier Ausführungen der erfindungsgemäßen Kammer.The invention is explained in more detail below with reference to the figures. Figures 1 and 2 show excerpts from the edges of two embodiments of the invention Chamber.

Diese besteht aus Blechen 1 mit abgewinkelten Kanten 2, welche miteinander verschweißt oder verlötet sind, 3.This consists of sheets 1 with angled edges 2, which with each other are welded or soldered, 3.

Bei Figur 1 weisen die Kanten 2 ins innere der Kaninier, bei Figur 2 nach außen. Erfindungsgemäß werden nun für die Kanten der Kammer vorgefertigte Bleche 4 verwendet, welche im rechten Winkel 5 gebogen sind. Diese Bleche 4 können vorzugsweise die doppelte Fläche der Bleche 1 aufweisen.In Figure 1, the edges 2 point into the interior of the rabbit, in Figure 2 to the outside. According to the invention are now prefabricated for the edges of the chamber Metal sheets 4 are used, which are bent at right angles 5. These sheets 4 can preferably have twice the area of the metal sheets 1.

Es wird eine Schweiß- bzw. Lötnaht eingespart.A weld or solder seam is saved.

Figur 3 zeigt ein Eckmodul für die erfindungsgemäße Kammer. Es besteht aus einem Blech 6, welches zweimal im rechten Winkel gebogen ist, mit senkrecht aufeinanderstehenden Biegekanten 5. Die dritte Kante 7 ist in der bekannten Art verschweißt oder verlötet. Das Blech 6 kann vorzugsweise die dreifache Fläche der Bleche 1 aufweisen.FIG. 3 shows a corner module for the chamber according to the invention. It exists from a sheet 6, which is bent twice at right angles, with perpendicular superposed bending edges 5. The third edge 7 is of the known type welded or soldered. The sheet 6 can preferably be three times the area of the Have sheets 1.

Es werden zwei Schweiß- bzw. Lötnähte eingespart.Two welding or soldering seams are saved.
