Description

[Detailed Description of the Invention] This invention provides a method for shielding (protection) from radio wave interference.
Concerning the creation of the partition part.

Today, various shielding materials are being developed to prevent radio wave interference.

However, due to the overwhelming consideration that places the highest priority on the shielding effect itself, it can be seen that the indoor environment, work efficiency, cost economy, and other issues are somewhat neglected.

For example, a radio wave shield partition υ made of ferrite fiber
In the construction of the tail, the surface of the ferrite-treated fiber body is exposed inside the chamber, so it is aesthetically unappealing and gives the impression that it has been specially sectioned. As for the living room environment, it tends to give a feeling of being heavy. Next, the work of applying or pasting the shielding material on the wall surface, etc. is something that is added after the work of creating the wall surface, etc., and in order to obtain a uniform finishing effect. , which requires a considerable amount of time and effort.

The present invention is intended to prevent high-frequency pulse generation from a radio wave generation room to the outside, for example, in a computer room, from affecting radio reception in the pond room, and to transmit it from another room into the room, for example, from a computer room in the room. This is a shield invention to prevent the radio wave shield room from malfunctioning due to interference from the outside, and the interior and exterior of the radio wave shield room are in no way different from other ordinary rooms. In addition, the room can be created with the same ease as working in a normal room.

To explain this with reference to drawings according to an embodiment of the present invention, the shield panel 1 includes a surface plate 2, a backing material 3,
It's like shield cloth 4.

The left and right edges of the surface plate 2 are bent in an L shape, and the cross section is tJ.
take shape.

The lining material 3 is a reinforcing material for the surface plate 2, and the shield cloth 4
Glue it to the surface plate 2, leaving the middle thickness of the surface. That is, when the shield cloth 4 is applied to the backing material 3, the back side of the panel is a uniformly flat surface (the lower end surface 6 of the L-shaped folded part 5.5), as shown in FIG. .6, the surface of the shield cloth 4 is a saw line).

The intermediate column 7 is a rectangular, vertically elongated column frame and has a shield end surface 8.8 against which the joint shield cloth 9 abuts.

As shown in Figure 3, the joint shield cloth 9 is attached to the middle pillar 7,
Close up the joint groove 10 from the back side of the shield panel l\,
It is something that can be suppressed.

Now, the partitioning work according to the present invention includes shield panels 1.111. which form ceiling panels and floor panels. (If there is a joint groove 10, place the joint shield cloth 9 in that part.
(and hold it down with the shield end face 8 of the intermediate column 7), and then attach the ceiling rail, floor rail, and joint connecting material (none of which are shown) 9.

Next, shield panels 1.11. Insert the upper end into the ceiling rail and fix it on the floor rail in order.
, , , intermediate pillars 7.71., 71., 71., 71., 71., 71., 71., 71. Conventionally, the shield panels 1 and 11+ are connected to each other using joint material (not shown) or the like from the indoor side.
This is a common practice and does not change in the present invention. In this embodiment, two small protrusions of the folded portions 5.5 that are close to each other are closed with a joint connecting material.

As described above, the radio wave shield room of the present invention is completed. If you look at the situation from the other side of the room, it will look like Figure 4.

Next, on the other remaining surface (outdoor side), install and connect the partition shibane panels in the same way, and the appearance of the room will be completed. In addition, in other aspects of partition shibanel,
A shield panel 1 may also be used.

As mentioned above, it has been described that a -wave shielding room can be created extremely easily, but the effect is as follows. It is the same woven fabric.

In the process of dyeing non-hygroscopic fibers (such as acrylic fibers) with copper ions, copper ions are diffused into the cyan groups to chemically bond copper between molecules. It is. This conductive/electrical fiber has an average of 5.85×10
conductivity of Ω, cm; 15. It has an excellent corona release ability due to its diameter of <S microns.

The radio wave shielding effect largely depends on the frequency, but in order to increase the effect, it is said that a volume resistivity of at least 1 cm or less is essential. The specific resistance values of the shield cloth 4 and the joint shield cloth 9 of the present invention are as described above.

Also, the effect (S) of the radio wave shielding material is 5 (db) 几 + A 10 B R: Reflection loss A: Absorption loss B: Internal reflection of the shielding material, but as a guide to the effectiveness, S is: 10dl)~30
If it is attenuated to db, the shielding effect is considered to be poor.

In the shield cloth 4 and joint shield cloth 9 of the present invention, VHF band from 30 MHz to 150 MHz, 400 MHz
1Od in a wide frequency range of the main four-wave band, including the z UHF band and the 30H2 to l OHz band.
The data is 3°db from b.

It can be seen here that the '-wave shielding chamber according to the present invention has excellent internal and external radio wave shielding effects. Moreover, the ceiling in a general room,
The interior and exterior are completely the same, including the floor and partitions. Further, there is no need for difficult work such as first setting up a partition wall or the like and then applying or pasting a shielding material on the wall surface.

The present invention is useful in industry and in people's daily lives, since it is possible to easily enlarge or reduce a room, install a new door, etc., or change the pattern of sushi, etc.

Claims (1)

[Claims] The shield cloth 6 and the joint shield cloth 9 are made by incorporating relatively non-hygroscopic fibers (for example, acrylic fibers) with copper, and using fine copper wires extending horizontally across the fiber body. This shield cloth 4 is made into a woven fabric, and is used for partition wall panels.
Affix it to the back side of a panel body such as a ceiling panel, floor panel, partition panel, door panel, etc., without protruding from the frame of the panel body, so that the back side of the panel body is a flat surface with a uniform X. , In the joint groove part, the joint shield cloth 9 is brought into contact with the back side of the panel body, and this is held down by a frame material such as an intermediate pillar, and the shield cloth 4 and the joint shield cloth 9 are not exposed in the interior of the room.
