報の提供がこれからのビルにおける１つの重要な課題と
なっている。(Conventional technology) Intelligent buildings generally share information and communication equipment such as complex electronic exchanges and computers to communicate information within the building and with the outside world. Along with this trend, the provision of faster and more accurate information has become an important issue for buildings in the future.
インテリジェントビルにおいてこのような課題に応える
ものとして、光ファイバー・ケーブルや同軸ケーブルを
利用したデータハイウェイ方式による情報ネットワーク
が検討され、提案されている。To address these issues in intelligent buildings, information networks based on data highway methods using optical fiber cables and coaxial cables have been studied and proposed.

がケーブル敷設のためにそれだけ余分にかかることにな
る。In this data highway method that uses optical fiber cables and coaxial cables, optical fiber cables and coaxial cables must be stretched to every corner (terminal equipment) in an intelligent building, and the construction cost and time required to lay the cables are high. It will cost you that much more.
その点、ビル内の通信に電波を使えばケーブル敷設は必

作するという問題が生じる。On that point, if radio waves are used for communication within a building, there is no need to lay cables, but in this case, on the other hand, noise radio waves are emitted to the outside, which is subject to regulations under the Radio Law. On the other hand, there is a problem in that the system malfunctions due to external radio waves, internal television intermediate frequency waves, radio waves from wireless microphones, and the like.

提案している。Therefore, the applicant has secured the electromagnetic shielding performance of the entire building by constructing the frame by pouring ferrite-containing concrete or mesh-containing concrete, or by using the sprayed tile coating itself, thereby ensuring that the building is subject to regulations under the Radio Law. We are separately proposing an intelligent building that allows wireless communication within a building by freely selecting any frequency.

という問題もある。However, if the electromagnetic shielding structure described above is adopted, the concrete becomes expensive, and additional steps are required to add ferrite and mesoche into the concrete, which not only increases the overall construction cost but also makes it difficult to improve the electromagnetic shielding performance. There are many technical problems. Another problem is that the method of making the frame itself an electromagnetic shielding structure cannot be applied to existing buildings.

る。In one embodiment of the present invention shown in FIG. 1, the electromagnetic shielding properties of the outer wall portion are enhanced by the way in which the inner wall heat insulating material and the conductive material are attached. That is, first, a concrete wall 2 is cast by incorporating reinforcing bars according to the conventional construction method, then a mesoche material 3 is cast on the inner wall side, and then a heat insulating material 4 is placed on top of it. In order to save labor, the mesh material 3 may be covered with the heat insulating material 4 in advance, and the mesh material 4 may be placed at the same time as the concrete is poured, with the mesh surface facing the concrete frame. By doing this, there is no need to change the appearance (it can be treated on the inner wall side, so the scaffolding is NJE and construction is easy.Also, since zinc plating is sufficient as the material for the mesh material 3, it is possible to reduce costs. You can also try it out.
