Description of the Related Art In recent years, the influence of external radio waves on electronic devices such as electronic computers has become a problem, and various work rooms having an electromagnetic shield function have been developed to block such influences. There is. As a shield material for such an electromagnetically shielded room, a copper foil, a copper plate, or an iron plate is used, and a joint portion of these shield materials is soldered in a conventional method, and in the prefabricated method, the shield material is used. It used a metal panel that integrated the.

Therefore, there is a problem that it takes time and effort. In addition, if the tension of the wire net is not sufficient, there is a problem that the finishing material is loosened and the appearance is spoiled.

The second joint C may be formed together with the joint B, and the second joint C may be formed later when the required shield performance is changed. That is, when the shield effect required by the user is unknown, for example, the first wire netting material 11a as a shield material has a shield performance of 40 to 60 dB in one layer. If the radio wave interference occurs due to its small size, the second wire mesh material 11

Furthermore, since the wire mesh material 11 is pressed by the protrusions 22, the compressive force is concentrated on the tip, and a close contact is obtained. Moreover, since the cosmetic cover 25 covers the screws and the like, it does not impair the aesthetic appearance as in the conventional case.

で美観を損なうおそれが少なくなるThe present invention is constructed as described above,
The following effects can be achieved. (1) Since the wire mesh material is used as the shield material, the transparency is secured and the internal condition can be easily grasped from the outside. (2) By forming two independent shield layers,
The influence of electromagnetic wave leakage of each layer can be further reduced, and high shield performance can be obtained. (3) When medium shield performance is required from the middle of use, the second wire mesh material is attached from the outside so that the finishing material and the shield material can be removed without removing the finishing material as in the conventional case. -Since it is possible to appropriately change the shield performance, limit design of the shield effect according to the application, and select whether the wire mesh material as the shield material is single or double,
It can have a rational structure. (4) When the wire mesh material is doubled, the frame can serve as an insulating layer, and since the insulating material is required only at the joint portion and the middle portion can be omitted, the insulating material can be omitted. You can save. (5) Even if the wire netting material bends at the place where the screws are fastened, the underlying insulating packing material elastically deforms and gives a uniform tightening force to the wire netting material while maintaining the compressive force. It is unlikely to occur and can effectively prevent leakage of electromagnetic waves. (6) Since the presser foot is formed with the protrusions, the fixing interval can be set to be large, and since the protrusions press the wire mesh material, close contact can be obtained. (7) Since the cosmetic cover covers the screws and the like, it is possible to prevent the appearance from being spoiled. (8) When the unit elements E are used, it is only necessary to join the unit elements E to each other on site, so the construction is easy and the workability is improved, and the tension of the wire mesh material can be managed at the time of factory production. Since it can be done, there is less risk that the wire mesh material will loosen after construction and spoil the appearance.
