Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an electromagnetic shielding surface structure that can be constructed quickly and inexpensively at low cost and with simple construction by using a general light iron base or plaster board as a building material.
[0002]
[Prior art]
Buildings in the information age block unnecessary radiation from outside to protect internal devices from malfunctions, and on the other hand, block information leakage from computer systems and wireless LANs inside buildings. Therefore, ensuring information security is an essential requirement.
Recently, since the introduction of wireless LAN and the like has been rapidly deployed, it has become an important issue to eliminate channel shortage caused by mutual interference of communication carriers generated between adjacent wireless LANs.
[0003]
In order to achieve these required performances, it is carried out by constructing the building frame and openings such as windows and doorways with an electromagnetic shielding material, and making the entire building an electromagnetic shielding structure. It is necessary to provide an electromagnetic wave shield of 20 dB to 40 dB at 3 GHz.
As described above, in order to ensure the sound and reliable operation of office automation equipment and wireless systems in buildings, and to prevent secret leaks, the entire building may be completely shielded against electromagnetic waves with a predetermined specification. Is the best.
[0004]
However, the advancement of information communication is not limited to the demand for the electromagnetic shielding of office buildings that have the above performance requirements, but each room is also equipped with special purpose buildings such as theaters, hospitals, studios, etc. New performance requirements are beginning to emerge that require blocking unnecessary electromagnetic waves without impeding functionality.
[0005]
In addition to the electromagnetic shielding of the entire building, it is necessary to meet the demands that meet various usage patterns inside the building.
However, since there was no such requirement for conventional building members, there were almost no building members related to various parts of the building having a function capable of meeting the requirements.
[0006]
When constructing an electromagnetically shielded space, the shielding performance of the building is greatly affected by the processing accuracy at the joint portion of the shielding member.
Conventionally, the shielding treatment of the wall surface in the electromagnetic wave shielding building is carried out by stacking a shielding material such as an aluminum sheet and a carbon fiber sheet about 50 to 150 mm, and further bonding a conductive adhesive tape thereon. . Such superposition work is a very troublesome process, but greatly affects the electromagnetic shielding accuracy depending on the skill level of the installer.
[0007]
In addition, when building a wall surface by building multiple layers of building materials such as plaster boards in general construction, the construction material is laterally oriented so that the joint portions of the building materials do not match between adjacent layers. “Missing eyes” is used to overlap and overlay.
The “Missing” method has been used to achieve the desired results when the laminated construction method is used to ensure the strength of the wall and fire resistance measures, and is used in acoustic rooms where soundproofing is required. Because the mechanism for propagating in space is different, it is impossible to cut off radio waves by simply “sticking wrong” for electromagnetic wave shielding.
[0008]
[Problems to be solved by the invention]
The present invention has been improved in view of the above situation, and by adding some functions to general building members, by effectively combining the building members, electromagnetic shielding work in buildings It is an object of the present invention to provide a structure of a low-cost electromagnetic shielding surface that can be easily and reliably constructed.

DETAILED DESCRIPTION OF THE INVENTION
The structure of the electromagnetic wave shielding surface according to the present invention is basically constructed by a surface constituent member in which a conductor is pasted on one side and a metal base of a predetermined length, and the conductors are arranged in a bonded or misplaced manner. Therefore, it is configured in an electromagnetic shielding state.

I am trying.
Embodiments of the present invention will be described below with reference to the drawings.
[0017]
FIG. 1 is a perspective view showing the basic shape of the structure of an electromagnetic wave shielding surface according to the present invention. In the figure, 1 is an electromagnetic shielding surface, 2 is a light iron (hereinafter abbreviated as LGS) base as a building member, and 3 is a plaster board processed for electromagnetic shielding.
In the electromagnetic wave shielding surface 1 according to the present invention, a plurality of LGS substrates 2 are installed in parallel, and a plurality of plaster boards 3 are arranged between the LGS substrates 2. Since the plaster board 3 is mounted and installed in the lateral direction with the long side 35 superimposed on the surface 20 of the LGS base 2 as shown in the figure, the metal plate on one side of the plaster board is electrically conductive to the LGS base. It arrange | positions so that it may join in a state. In addition, since the plaster board is installed in a state in which the respective small openings 32 form the joint portion 4, the plaster board attached to each of the small openings is joined to the conductive state. Will be.
[0018]
Therefore, in the present embodiment, the metal plate on one side of the plaster board is joined in an electrically conductive state with the metal plate 20 of the fore edge 32 and the metal surface 20 of the LGS base 2 interposed therebetween, so the LGS base 2 and the plaster board The electromagnetic wave shielding surface 1 constituted by 3 is constituted as an integral metal plate over the whole, and forms a complete electromagnetic wave shielding surface.
[0019]
FIG. 2 is a perspective view showing an LGS base and a plaster board forming the electromagnetic wave shielding surface 1 according to the present invention.
The LGS base 2 shown in FIG. 2A is a general building member and is a metal channel, so that it can be used as it is as an electromagnetic shielding material. In order to shield the electromagnetic wave, it is necessary to secure an overlapping width of the metal surfaces of 50 mm or more, and therefore, an appropriate width is selected and used.
The LGS base 2 is electrically conductively joined to the metal surface pasted on one side of the plaster board as described above when constructing the structure of the electromagnetic wave shielding surface. It may be necessary to coat the kimono so that it does not exist.
[0020]
In the plaster board 3 shown in FIG. 2 (b), thin metal plates 33 and 34 are pasted on the surface of one side 31 and the small edge 32 of the plaster board 30 which is a normal building member, and the other side 36 is left as a base. Thus, a single electromagnetic wave shielding member is configured.
When the wall surface is formed by the plaster board 3, the LGS base 2 is essential to support the plaster board 3. For this reason, since the joining on the long side 35 of the plaster board 3 is performed on the surface 20 of the LGS base 2, there is no problem in the conductive joining at the joining portion without arranging a metal plate on the long side of the plaster board. .
In the illustrated plaster board, a metal plate 34 continuous with the metal plate 33 is attached to the forehead. However, as will be described later, it is clear that the structure of the electromagnetic wave shielding surface is formed by overlapping the plaster boards. In this case, since the conductive bonding at the small edge of the plaster board is not necessary, it is possible to reduce the cost by omitting the metal plate 34 at the small edge portion.
[0021]
3 to 5 show structures of various electromagnetic wave shielding surfaces in which the LGS base 2 and the plaster board 3 are combined.
FIG. 3 shows an embodiment in which another plaster board 5 is overlapped on the metal plate side and “misplaced” on the basic shape of the electromagnetic wave shielding surface 1 shown in FIG.
In the case of the electromagnetic wave shielding surface 6 in the present embodiment, the electromagnetic wave shielding surface 1 established by the LGS base 2 and the one-layer plaster board 3 is constructed. In addition to this, since the plaster board 5 is laminated so that the single-sided metal plate 33 is in contact with the first-layer plaster board 3, the joint surface 4 between the plaster boards 3 and 5 is the other layer that is “misplaced”. It is closed by a metal plate 33 on one side of the plaster board.
For this reason, since the joining surface of each plaster board is configured so as not to generate a gap directly or with a thickness of the plaster board, a more reliable electromagnetic wave shielding treatment is performed.
[0022]
Further, the laminated structure described above is such that the metal plate 33 of the plaster board 5 is joined to the metal plate 34 attached to the edge of the first-layer plaster board 3, so that the electromagnetic wave shielding surface 6 has a double structure. Since the electromagnetic wave shield state is formed, the embodiment can be applied to an electromagnetic wave shield having a large attenuation rate.
[0023]
FIG. 4 shows an embodiment of “mis-sticking” in which another plaster board 5 is superposed on the substrate side on the electromagnetic wave shielding surface 6 shown in FIG.
In the case of the electromagnetic wave shielding surface 7 in the present embodiment, the electromagnetic wave shielding surface 1 established by the LGS base 2 and the one-layer plaster board 3 is constructed, but the plaster board 5 is the base side on which the metal plate 33 is not attached. Are stacked so as to be in contact with the first plaster board 3.
For this reason, the joint surfaces 4 of the plaster boards 3 are closed with a gap corresponding to the thickness of the two layers of the plaster board by a metal plate 33 on one side of the other layer of the plaster board that is “misplaced” to each other. The shield treatment is strengthened.
[0024]
In the above laminated structure, the metal plates 33 of the plaster boards 3 and 5 are separated from each other, and thus are not joined to the metal plate 34 attached to the forehead. This is an embodiment in which the attenuation rate is increased because a heavy electromagnetic shielding state is formed.
[0027]
In the example of the electromagnetic wave shielding surface 9 shown in FIG. 5 , the plaster board 3 is in contact with the LGS base 2 on the substrate side where the metal plate 33 is not attached. For this reason, a conductive state through the LGS base 2 is not formed between the plaster boards 3, but the plaster board 5 is laminated so that the metal plate 33 contacts the metal plate 33 on one side of the plaster board 3. The joint surfaces 3 and 5 are directly closed by the metal plate 33 on one side of the other-layer plaster board that is “misplaced”.
For this reason, it can be constructed without care when installing the LGS substrate and the plaster board. Therefore, the joint surface of each plaster board is configured so as not to generate a gap, and a reliable electromagnetic wave shielding treatment is performed.
[0028]
As described above, the structure of the electromagnetic wave shielding surface according to the present invention is constructed by a surface constituent member having a conductor pasted on one side and a metal base of a predetermined length, and the conductors are arranged in a joint or misplaced manner. Because it is configured to be in an electromagnetic shielding state, it can be constructed easily and with high accuracy by a general boarder who is not an electromagnetic shielding specialist using low-cost members, so the entire electromagnetic shielding construction Cost reduction and construction period are shortened.
[0029]
As mentioned above, although the present invention has been described in detail based on the embodiment, the structure of the electromagnetic wave shielding surface according to the present invention is not limited to the above embodiment at all, and is within the scope of the gist of the invention. Naturally, various changes are possible.
