JOINT STRUCTURE OF ELECTROMAGNETIC WAVE SHIELD MEMBER
PROBLEM TO BE SOLVED: To provide a joint structure of an electromagnetic wave shield member having an electromagnetic wave shield performance of 100 dB or more in a wide frequency range even when an earthquake causes a large interlaminar deformation angle in an electromagnetic shielding room.MEANS: A slit w is provided between the edge portions of mutually adjacent shield members 2, 2, ... in which the our peripheral edges are clamped by a vertical bar 3a, a horizontal bar 3b, and a pressing edge member 4, and in a state where a wool-like gasket 5 is stacked so as to cover the slit w from both sides or one side, mutual electrical continuity of the shield members 2, 2, ... separated by the slit w is ensured and generation of gaps where electromagnetic waves leak is suppressed even during earthquakes by piercing and fastening the vertical bar 3a, the horizontal bar 3b, and the pressing edge member 4 with the binding materials 6, 6, ... and crushing the wool-like gasket 5 to bring the shield members into tight contact with each other.SELECTED DRAWING: Figure 2
【課題】地震により、電磁波シールドルームに大きな層間変形角を生じても、広い周波数域において、100dB以上の電磁波シールド性能を有する電磁波シールド部材の接合部構造を提供する。【手段】縦桟3aおよび横桟3bと押え縁材4とにより縁端部四周が挟持されている相隣接するシールド部材2、2、…の縁端部間にスリットｗを設け、そのスリットｗを両面もしくは片面から覆うように、ウール状ガスケット5を重ねた状態で、綴り材6、6…にて、縦桟3aおよび横桟3bと押え縁材4とを貫通して締め付け、ウール状ガスケット5を押しつぶすことにより密着させて、スリットｗで分断されているシールド部材2、2、…相互の電気的導通性を確保すると共に、地震時においても電磁波が漏洩する隙間の発生を抑制する。【選択図】 図２
