Furthermore, technology that prevents electromagnetic waves from emitting or entering is also required in computer centers, hospitals, and AV conference rooms that handle precision electronic equipment. In particular, recently it has been discovered that radio waves emitted by computers and displays can be easily detected using relatively simple equipment, so the eavesdropping of radio waves leaking from computers and other electronic devices that handle information has become a problem.

以下に説明する。An application has already been filed for an intelligent building that uses electromagnetic shielding members to configure the frame and openings such as windows and doorways, making the entire building an electromagnetic shielding structure that enables communication within the building using radio waves. In this intelligent building, electromagnetic waves are shielded throughout the building by using mesh-filled glass or glass covered with conductive film for the windows and entrances that open into the building. An example of ensuring the electromagnetic wave shielding performance of a window by using glass containing mesh or glass to which a conductive film is attached (Japanese Patent Application Laid-Open No. 112886/1986) will be described below.
第４図及び第５図はガラス窓の電磁波遮蔽方法の１例を

45 indicates conductive rubber and sash.

電性を得ることができる。In FIG. 4, a window glass 41 has an electromagnetic wave shielding layer 42 made of a conductive material such as a mesh or a film therein, and a conductive paint is applied to the ends thereof. The conductive rubber 44 compresses and fixes the window glass 41 to the conductive sash 45. The conductive paint 43 and the conductive rubber 44 create electrical conductivity between the electromagnetic wave shielding layer 42 of the window glass 41 and the sash 45. gender is ensured. In particular, conductive rubber 4
4, the conductive paint 43 is electrically connected to the electromagnetic wave shielding layer 42 by compressing and fixing the window glass 4I.
Since the contact pressure between the sash 45 and the conductive rubber 44 becomes sufficiently large, and the contact pressure between the sash 45 and the conductive rubber 44 also becomes sufficiently large, the contact resistance becomes small and sufficient conductivity is obtained. be able to.

することができる。The example shown in FIG. 5 is an example in which a window glass 46 is vacuum-deposited with metal or a conductive film is attached to form the electromagnetic wave shield N41. In this case, since there is an electromagnetic wave shielding layer 47 on the surface of the window glass 46, the electromagnetic wave shielding layer 47 and the conductive rubber 44 can be directly connected to each other without applying conductive paint 43 to the edges as shown in FIG. It is possible to ensure conductivity between the two.

る。In FIG. 6, reinforcing bars 54 are used to reinforce the concrete of the frame 56, and are ultimately grounded through these reinforcing bars 54. Therefore, the embedded anchor 53 is embedded in the concrete of the frame 56 by integral casting, and an earth bond is established with the reinforcing bar 54 to the embedded anchor 53. Therefore, by welding the embedded anchor 53 from the sash frame 51 at one or more locations, the conductivity from the sash frame 51 to the reinforcing bars can be improved, and the electromagnetic wave shielding performance of the entire window can be improved.

充分確保できないという問題がある。When imparting magnetic wave shielding performance to glass as described above, a cloth-like material (mesh) woven from fine wires that has electromagnetic wave shielding performance is sandwiched between two pieces of glass, or a certain amount of film thickness is used. A metal film containing the material is attached to the glass surface. In order to improve the electromagnetic wave shielding performance of a window opening using such glass, it is generally necessary to increase the thickness of the electromagnetic wave shielding layer. However, there is a problem in that increasing the thickness of the electromagnetic wave shielding layer deteriorates the sunlight transmission performance. Further, depending on the composition and processing method of the electromagnetic wave shielding layer, there is a problem that sufficient electromagnetic wave shielding performance cannot be ensured at the target frequency.

The electromagnetic wave shielding performance can be improved by the other electromagnetic wave shielding layer. Furthermore, the electromagnetic wave shielding performance can be further enhanced by changing the interval between the electromagnetic wave shielding layers according to the characteristics and frequency of the electromagnetic wave shielding layers and effectively reflecting/absorbing and resonating 1 between the magnetic wave shielding layers.

る。The electromagnetic wave shielding transparent body with a multilayer structure of the present invention does not have a single electromagnetic wave shielding layer as shown in FIG. 1, but has a plurality of electromagnetic wave shielding layers arranged with distance between them. . In the example shown in FIG. 1 (al), the electromagnetic wave shielding film 1.3 is placed so as to sandwich the glass 2 from both sides, so that the electromagnetic wave shielding film 1.3 is separated by the thickness of the glass 2. In (b), a glass 4 is further stacked on top of the electromagnetic wave shielding film 3 via an interlayer film or an adhesive layer (not shown), and the electromagnetic wave shielding film 1 is covered with the glass 2.4.
It is designed to sandwich lI3. By doing so, the electromagnetic wave shielding films 1 and 3 are separated by at least the thickness of the glass 2, and the electromagnetic waves that have passed through one of the electromagnetic wave shielding films are absorbed between the electromagnetic wave shielding films 1 and 3. /Resonance is attenuated by reflection, and electromagnetic wave shielding performance can be further improved than in the case of only one electromagnetic wave shielding film. The figure fe) is the electromagnetic wave shielding film 1.3 shown in the figure Mt.
This figure shows a cross section of a laminated glass structure having a glass 2.4 and a laminated interlayer film or an adhesive layer as required.
A sealing space 12 is provided by adhering a sealing member 11 along the periphery between the glass plates 9 and 14.
It is of a multi-layer transparent type with an electromagnetic wave shielding film 10.13 provided on the inner surface. Therefore, in this example, the distance between the electromagnetic wave shielding films 10 and 13 can be set by the sealing member 11 regardless of the thickness of the glass 9.14.

させることができる。The electromagnetic wave shielding performance is inversely proportional to the resistance value of the electromagnetic wave shielding surface. However, increasing the film thickness increases the electromagnetic wave shielding performance, but reduces the sunlight transmission performance. Therefore, in order to maintain a certain degree of sunlight transmission performance, it is necessary to reduce the film thickness. Therefore, as shown in FIG. 2 (al), the thickness of the electromagnetic wave shielding film 21 is reduced to ensure the transmission performance, and the conductor 2 made of a good conductive wire material such as copper or silver is
2 is provided separately on the surface of the electromagnetic wave shielding film and each of the conducting wires 22 is connected to the electrodes 23 and 24, the surface resistance of the electromagnetic wave shielding layer is regulated by the distance to the nearest conducting wire 22, so that the resistance is further reduced. It is possible to improve the electromagnetic wave shielding performance. The same figure (bl) shows an example in which the surface of the electromagnetic wave shielding film is divided into a mesh shape by providing not only vertically divided conductors 25 but also horizontally divided conductors 25.Conductors 22 and 25
Unlike an electromagnetic shielding mesh, the material itself does not play the role of shielding electromagnetic waves, but rather reduces the resistance of the surface. Therefore, unlike electromagnetic wave shielding meshes, there is no need to arrange them as densely as possible, so it is possible to improve the electromagnetic wave shielding performance without reducing the sunlight transmission performance of the face material itself.

来のもつ透明感、光の透過率、反射率が異なってくる。By the way, for example, an electromagnetic wave shielding transparent body made of glass or the like whose surface is coated with a metal, a metal oxide, or a laminate thereof, depends on the type, amount, and amount of the coated metal, metal oxide, or laminate thereof. Due to stabilization treatments, etc., it has various hues and reflective colors, and the inherent transparency, light transmittance, and reflectance of transparent objects vary.

In such cases, it is possible to give the building a color tone and reflective performance that match the building's planning intent. FIG. 3 shows an example of this correspondence.

。FIG. 3 (Al is a tint/reflection performance adjusting layer 33 on an electromagnetic wave shielding transparent body consisting of a transparent glass 31 and an electromagnetic wave shielding film 32.
In the same figure (bl is i magnetic wave shielding film 32
This is an example in which the hue/reflection performance adjustment N33 is arranged on the opposite side. In addition, in the same figure (C1, +d+ is an example in which a heat ray absorbing glass 34 is used in place of the transparent glass 31 shown in ta+ in the same figure, and in the same figure +81, (fl) is an example in which a heat ray reflective glass consisting of glass 37 and reflective N38 is used. The heat ray absorbing glass 34 is made by adding trace amounts of metal oxides such as nickel, chromium, cobalt, iron, selenium, etc. to soda lime silicate glass, and it becomes color-absorbing glass. In Figures (C) and (d+), the tint/reflection performance adjustment layer 36 may be omitted. Similarly, for heat ray reflective glass, a metal or metal oxide thin film with excellent heat ray reflection performance is coated on one surface of the transparent body using a special method. Because it is coated with a mirror effect, a unique color tone is obtained.
In this case, the tint/reflection performance adjusting layer 40 can be omitted.

For example, in buildings called shield rooms that require a high degree of electromagnetic shielding performance, the buildings have no windows because the windows cannot provide sufficient electromagnetic shielding performance. However, as is clear from the above description, according to the present invention, since the electromagnetic wave shielding transparent body has a multilayer structure, high electromagnetic wave shielding performance can be obtained while maintaining sufficient sunlight transmission performance.
