高い周波数の領域において優れたシールド特性を有する
電磁シールド窓のシールド装置を提供することにある。In recent years, wireless systems and the like used inside and outside buildings have been developed, and the number of attempts to effectively use radio waves as information transmission means is rapidly increasing. Along with this, measures for preventing eavesdropping by radio waves and preventing malfunctions of various OA devices due to radio waves have been highlighted. As one of the countermeasures, demand for what is called a shield building, which shields the building space from electromagnetic waves, is rapidly increasing. The basic theory of constructing an electromagnetic shield is to electrically enclose a floor, wall, and ceiling hexahedron with a conductive material. Of course, the "windows" that compose the building space must also be electromagnetically shielded, and each glass manufacturer is developing "electromagnetic shield glass." The effect of the electromagnetic shield cannot be expected only by fixing the electromagnetic shield glass to an ordinary aluminum, stainless steel or steel sash (window frame) by the conventional construction method. The reason is that the electrically conductive portion of the electromagnetic shield glass and the sash are electrically insulated. The above-mentioned conventional shield device for an electromagnetic shield window has the holding groove 2
The surface of the inner annular frame 1a and the annular frame 3 of the electromagnetic shield glass 3
and a surface of the ring-shaped frame 1b in the holding groove 2 and a surface of the ring-shaped frame 3e of the electromagnetic shield glass 3 are respectively filled with conductive backup materials 4 and the inside of the backup material 4 is held. The seal ring material 5 is filled between the surface of the annular frame 1a in the groove 2 and the surface of the electromagnetic shield glass 3 and between the surface of the annular frame 1b in the holding groove 2 and the surface of the electromagnetic shield glass 3, respectively. However, the close contact between the surfaces of the annular frames 1a and 1b and the surface of the annular frame 3e of the electromagnetic shield glass 3 and the surface of the conductive backup material 4 is insufficient, so that a sufficient electric conduction state is established. However, in such a non-tightened state, only the performance shown by the two-dot chain line and the one-dot chain line in FIG. 6 can be obtained, and in a building space where high electromagnetic shielding property at high frequency is required, The drawback of not being able to adequately meet the demand A. The problem to be solved by the present invention is to provide a shield device for an electromagnetic shield window which does not have the above-mentioned drawbacks of the prior art, in other words,
An object of the present invention is to provide a shield device for an electromagnetic shield window having excellent shield characteristics in a high frequency region.

易い。As shown in FIGS. 2 to 5, a large number of through holes are formed in one of the groove-shaped rising portions 11b of the first frame body 11 at intervals in the longitudinal direction, and each through hole corresponds to each through hole. Then, the long nuts 17 are fixed by a fixing means such as welding, the tightening bolts 18 are screwed into the long nuts 17, and the tightening bolts 18 are screwed in. The back surface 14b 2 of the side portion 14b can be pressed. A large number of long holes 14a 1 are formed in the side portion 14a of the fourth frame body 14 at intervals in the longitudinal direction thereof, and a large number of long holes 14a 1 are formed in the side portion 13a of the third frame body 13 in the longitudinal direction thereof in accordance with the intervals. The screw hole 13a 1 is formed. The screw Bs 2 inserted into each long hole 14a 1 of the side portion 14a of the fourth frame body 14 is screwed into the screw hole 13a 1 of the side portion 13a of the third frame body 13 to move the fourth frame body 14 into the third frame body. Thirteen
It can be fixed to. The interval between the long nuts 17 of the first frame 11 and the long nuts 17 is set to, for example, 125
and mm, the distance between the elongated holes 14a 1 and the elongated hole 14a 1 of the fourth frame 14, for example, to 200 mm. The reason for doing the above is that the integer ratio (15
This is to avoid 0 mm). Radio waves easily leak at 150 mm intervals.
