[Problems to be solved by the device]

 Since the above conventional electromagnetic shield interior material uses a heavy material such as a metal foil made of electrolytic iron foil, etc. as an electromagnetic wave shield layer, workability for connecting the electromagnetic shield interior materials to each other is poor, and further soldering work is required. Therefore, the number of man-hours required for the work is large, and there is a problem in work safety.

Therefore, there are technical problems to be solved in order to improve workability and safety while mounting the electromagnetic shield interior material, and the present invention solves the problem. The purpose is to do.

[0006]

[Means for Solving the Problems]

 This invention is proposed in order to achieve the above-mentioned object, and an interior material having a glass fiber electromagnetic shield material as a main element is mounted on the surface of the building base material, and the interior material and the building base material are Electromagnetic shield in the space between the building base material and the interior material, with a metal tape with a conductive adhesive being interposed between the interior material and the interior material. It provides the structure.

[0007]

[Action]

 The interior material mainly composed of glass fiber electromagnetic shield material is installed on the surface of the building base material. At this time, a metal tape with a conductive adhesive is interposed between the back surface of the joint portion of the adjacent interior material and the front surface of the building base material and which is laid across both of the adjacent interior materials. The interior material is affixed to the building base material by being mounted and pressed from the surface. Therefore, the electromagnetic shielding acts over the entire surface of the interior material, so that the space defined by the building base material on which the interior material is mounted is effectively electromagnetically shielded.

[0008]

【Example】

 Hereinafter, an embodiment of the present invention will be described in detail with reference to FIGS. In FIG. 1, reference numeral 1 is a construction base material for forming a space to be shielded by an electromagnetic field. An interior material 2 is attached to the surface of the building base material 1 to protect the space from various electromagnetic waves. Thus, the interior material 2 is composed of the glass fiber electromagnetic shield material 3 as a main element, and the back adhesive material 4 is attached to the back surface of the electromagnetic shield material 3 and the finishing layer 5 is attached to the upper surface. ing. The end of the backing strip 4 is omitted, and a metal tape 6 made of copper foil with a conductive adhesive is attached thereto. Thus, the interior material 2 is formed as a wallpaper, but not limited thereto. The materials of the backing material 4 and the finishing layer 5 should not be specified, but nonflammable materials may be used.

Thus, the molded interior material 2 is attached to the surface of the building base material 1 as wallpaper. Therefore, the procedure will be described. First, the interior materials 2, 2 ... Are sequentially attached to the surface of the building base material 1, but the edges of the mutually adjacent interior materials 2, 2 ... are overlapped, and the overlapping portions are overlapped. The overlapping portion is cut from the upper surface of the cutter using a cutter (not shown). In that case, both interior materials 2, 2 can be butt-matched at the cut end of the cutter. Therefore, the abutting portion is lifted, and by the lifting operation, both the interior materials 2 and 2 form a predetermined gap, and a constant gap is generated between the interior base material 1 and the interior base material 1. Therefore, after inserting the metal tape 6a with a conductive adhesive into the space and adhering it to the surface of the building base material 1 at the portion corresponding to the joint 7 between the interior materials 2 and 2, the metal tape 6a is made to adjoin the lifted adjoining material. The edges of both the interior materials 2 and 2 are returned to their original positions and pressed from the upper surface to bond the interior materials 2 and 2 to the building base material 1. Then, the interior materials 2, 2 ... Are mounted on the surface of the building base material 1 partitioning a predetermined space by sequentially repeating such a procedure, and the space is electromagnetically shielded.

Next, another embodiment of the present invention will be described with reference to FIG. The same parts as those of the embodiment shown in FIG. 1 are designated by the same reference numerals and the description thereof will be omitted. In the figure, the metal tape shown in FIG. 1 is not attached to the edge portion of the back surface of the interior material 2 formed in the wall paper specification. Thus, of the interior materials 2 and 2 to be joined to each other, the interior backing material 4 is omitted at the edge of the back surface of one of the interior materials 2, and a metal made of the same material as that of the above-described embodiment is used here. The metal tape 6b is attached so as to project outward from the end.

Therefore, in this embodiment, the interior material 2 in which the metal tape 6b is adhered to the surface of the building base material 1 is abutted with the metal tape 6b being the lower surface, and further adjacent In the case of the mounting material 2, both of the interior materials 2 and 2 are applied by applying the lacking portion of the back lining material 4 at the edge of the interior material 2 without the metal tape 6b to the upper surface of the protruding portion of the metal tape 6b. And the joint 7 between the interior materials 2 and 2 and the interior materials 2 and 2 are reinforced by the metal tape 6b. It will be bonded to the material 1. By repeating such a procedure in sequence, the interior materials 2, 2 ... Are adhered to the surface of the building base material 1 in the form of wallpaper to electromagnetically shield a predetermined space.

However, the above-mentioned procedure should not be limited to the above-mentioned one, but the interior materials 2, 2 ... Affixed as wallpaper specifications have such an aesthetic appearance and the electrical performance as the electromagnetic shield material 3 is improved. Can hold enough. Originally, the metal tapes 6, 6a, 6b have better shielding performance than the glass fiber type electromagnetic shielding material 3, so that the performance does not decrease due to the connection, and the electromagnetic shielding performance is improved as the number of connecting points increases. Suru Then, an experiment was conducted on a space to be electromagnetically shielded by using the electromagnetic shield interior material 2 of the present invention, and a shielding performance of 40 dB or more was obtained in the electric field mode of 150 KHz to 1 MHz and the plane wave mode of 30 MHz to 1 GHz. Therefore, it was found that the present invention is suitable for electromagnetic shield enforcement in offices, computer rooms, research laboratories, etc., where a considerable degree of electromagnetic shield performance is required.

The present invention can be variously modified without departing from the spirit of the present invention, and it goes without saying that the present invention extends to the modified version.

[0014]

[Effect of device]

 As described in detail in the above embodiments, the present invention is nonflammable because it uses a glass fiber electromagnetic shield material as an electromagnetic shield material, and when it is attached to a building base material as wallpaper specifications, the interior material is extremely Since it is lightweight, it has good workability, and since it does not require work with a soldering iron as in the conventional case, the work is easy, quick, and safe, and a great cost reduction can be expected.

Furthermore, since the interior material itself can be formed thin, the effective area of a predetermined space to be electromagnetically shielded can be widely used, and the appearance as an interior material and the electrical performance as an electromagnetic shielding material can be improved. It constitutes an excellent device.
