Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure of an electromagnetic wave shielding surface which can be constructed quickly and inexpensively with low cost and simple construction by attaching a conductive member to a general plaster board in advance as a building material. Method and electromagnetic shielding building components.

2. Description of the Related Art Buildings in the information age are designed to block unnecessary radiated radio waves from outside to protect internal equipment from malfunction.
Conversely, it is an essential requirement to secure information security by preventing information from leaking from the computer system or wireless LAN inside the building to the outside.

[0003] In recent years, since wireless LANs and the like have been rapidly introduced, it is important to solve the shortage of channels caused by mutual interference of communication carriers generated between adjacent wireless LANs. ing.

[0004] In order to achieve these required performances, the building body and the openings such as windows and doorways are constructed of an electromagnetic wave shielding material using expanded metal or conductive non-woven fabric, and the whole building is constructed. An electromagnetic shielding structure has been adopted, and 30 MHz at 1 MHz to 10 GHz.
It is necessary to provide an electromagnetic wave shield of about 40 dB.

As described above, in order to ensure the sound and reliable operation of OA equipment and wireless systems in a building and to prevent leakage of confidential information, the entire building must be completely shielded with electromagnetic waves according to predetermined specifications. However, the development of information and communications is not limited to the demand for electromagnetic shielding in office buildings, which have the above-mentioned performance requirements, and in rooms with special applications such as theaters, hospitals, and studios. New performance requirements have also begun to emerge, such as the need to block unnecessary electromagnetic waves without disturbing the original functions provided by.

[0006] With the above-mentioned demand expansion, in addition to shielding the entire building from electromagnetic waves, it is necessary to meet demands that meet various usage forms inside the building.

[0007] However, since such requirements did not exist in the conventional building members, there were almost no building members having functions capable of meeting the requirements in the building members related to various parts of the building. Was.

[0010] That is, as shown in FIG. 10, the conventional shielding treatment in an electromagnetic wave shielding building is performed by expanding an architectural member 41 supported on a general light iron (hereinafter abbreviated as LGS) 40 as a base. A shielding material 42 made of a conductive non-woven fabric such as a metal, an aluminum sheet, or a carbon fiber sheet is attached, and the ends of the shielding material 42 are connected to each other by 50 to 150.
After the superposition 43 of about mm, a conductive adhesive tape is further stuck thereon.

When the living room in contact with the outer wall surface is shielded by an electromagnetic wave, as shown in FIG. 11, an expanded metal or conductive nonwoven fabric 46 is superposed 47 on the inner side wall surface of the outer wall surface 45 to form an electromagnetic wave shield. After the layer 48 is constructed, it is necessary to separately construct a finishing wall 50 on the indoor side by using LGS or the rim material 49.

[0010] In particular, the outer wall surface 45 in a cold region or the like has a
It is necessary to construct a heat insulating material 51 such as urethane foam as shown in FIG. When such an outer wall surface is shielded by an electromagnetic wave, it is necessary to avoid interference between the heat insulating material 51 and the electromagnetic wave shield layer 52. Therefore, a wall 55 of an LGS 53 and a plaster board 54 is provided on the indoor side, and this is used as a base. The electromagnetic wave shielding layer 52 will be applied.

In this case, the shielding material 56 is also constructed by laminating its ends by about 50 to 150 mm and then bonding a conductive adhesive tape.

When a space shielded by electromagnetic waves is constructed by the above construction, the shielding performance of the building largely depends on the processing accuracy at the joints of the shielding members. Despite the troublesome processing, the skill level of the installer has a great influence on the electromagnetic wave shielding accuracy, resulting in a large increase in cost and a long construction period.

In particular, in the case where the living room in contact with the outer wall surface is shielded by an electromagnetic wave, the construction of the electromagnetic wave shield and the finishing of the interior around the outer wall are performed in separate steps, which causes a need for a construction period and cost. .

At the same time, the electromagnetic tape is sandwiched between the conductive tape 3 affixed to the metal sheet 12 and the metal surface of the LGS 6, thereby ensuring a predetermined electromagnetic wave shielding performance.

As described above, another construction method of the electromagnetic wave shielding surface according to the present invention uses a building member formed by extending a metal sheet attached to a front surface manufactured in advance from the front edge to the rear surface. Since it is constructed by supporting with a support member, there is no work to overlap the end while attaching the conductive member to the wall surface, and it is installed on the back surface while interposing the support member surface at the joint of the fore edge By improving the electromagnetic wave shielding performance by joining the metal sheet in a conductive state, the electromagnetic wave shielding work can be performed easily and with high precision even by ordinary board workers who are not specialized in electromagnetic wave shielding while using low-cost members. In this way, the construction cost and the construction period of the entire electromagnetic shielding work are reduced.

The electromagnetic wave shielding surface can be configured by constructing the plaster board 31 on the inner surface of the heat insulating material 35 by the GL method, and the subsequent construction is the same as in the above embodiment.

The heat insulating material 35 is commercially available as a processed board material in which urethane foam or the like is closed with a metal sheet. When this is used, the metal sheet can be used also as an electromagnetic wave shielding material. Therefore, it is cost effective.

As described above, the method of forming an electromagnetic wave shielding surface according to the present invention for a living room in contact with an outer wall surface can be performed simultaneously with interior finishing while omitting LGS and the like, by changing the electromagnetic wave shield of the living room in contact with the outer wall surface. By installing, it is possible to improve the electromagnetic wave shielding performance by a simple method of interposing the supporting member surface at the joint of the small edge surface, so that it can be constructed at low cost by omitting the used members, and specializing in electromagnetic wave shielding Even if it is not necessary, the electromagnetic wave shielding work can be performed easily and with high precision.
