<p>PURPOSE:To construct efficiently a plurality of electromagnetic wave shielding rooms in the same building. CONSTITUTION:Electromagnetic wave shielding rooms 31 and 32 in the same building 2 are made to communicate with each other via an electromagnetic wave shielding duct 12, both sides of the duct 12 are respectively connected electrically with each one of electromagnetic wave shielding surfaces 3a of both rooms 31 and 32 and at the same time, a power use filter 6 and a signal conductor filter 7 are provided on one of the shielding surfaces 3a of the room 31 and an electromagnetic wave shielding piping 10 is provided in one of the shielding surfaces 3a of the room 31. An outdoor power cable 8a is connected with an indoor power cable 8b via the filter 6, an outdoor signal cable 9a is connected with an indoor signal cable 9b via the filter 7 and with a water supply and exhaust pipe 11 made to insert in the piping 10, the cables 8b and 9b and part 1 la of the pipe 1 1 are made to insert in the duct 1 2 to introduce in the other room 32.</p> |
