ABSTRACT:
In a building having electromagnetically shielded sections formed by using electromagnetic shielding members as structural members for outer walls, floors an so forth, a zone partitioned with a bearing wall structure having walls such as a fire wall (12) reaching a floor slab is formed as a unit of the electromagnetically shielded space, thereby eliminating the need for an additional process of forming a rising portion or a partition formed on a partition wall formed below a double-ceiling. At the connection between the floor slab and the wall, a space formed therebetween is filled with asbestos (42), and the floor slab and the wall are integrally connected electrically, and a space between a column (51) and a floor decking plate (52) is covered with a shielding plate (54) while the floor slab is fabricated in an ordinary manner, thus forming electromagnetically shielded sections. A core 104 is disposed between office rooms (102, 103), and doors in the partition wall provided between these rooms are formed with an electromagnetic shielding structure so that an electromagnetically shielded zone is formed for each room by shutting off propagation of noises from the core section and preventing interference between electric waves used in adjacent stories.
