ことにより上下階の電磁遮蔽を行うようにしている。However, if the building is being constructed using RCM construction or SRC construction, for example,
Reinforced concrete structures, such as structures, have the property of transmitting electromagnetic waves well, so conventionally, electromagnetic shielding materials were used to protect walls,
Electromagnetic shielding is provided for openings such as windows and the floor. That is, as shown in FIG. 7, in the wall 102 and window 103,
Electromagnetic shielding material 101 is placed on walls 102 and windows 103 to prevent electromagnetic waves from entering from outside.
Since a grounded deck plate 105 made of a steel plate is employed in the building, this deck plate 1o5 is used to provide electromagnetic shielding between the upper and lower floors.

Therefore, the space between room B and the adjacent room A is completely electromagnetically shielded. Therefore, from adjoining room A to floor 3
The electromagnetic wave γ that enters through the concrete slab 4 of
is completely blocked, and electromagnetic waves leaking from room B into adjacent room A are also completely blocked.
