Outer circumference of the conductive film 5 is pressed by a conductive gasket 6 and connected electrically, and then the conductive gasket 6 is secured by a sealant 7. Accordingly to the structure, the window opening can be protected against leakages of electromagnetic waves and contamination, while enhancing durability at low cost.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention belongs to the technical field of an electromagnetic shielding building in which an electromagnetic shielding layer is formed on floors, ceilings, walls and window openings by using an electromagnetic shielding material to form an electromagnetic shielding space.

[0002]

2. Description of the Related Art When a radio communication system using radio waves is adopted, regulations of the Radio Law regarding the used frequency band pose a problem. Therefore, in order to freely select and set the frequency band to use and adopt a unique wireless communication method without being restricted by the Radio Law, the space inside the building was electromagnetically shielded from the outside. Construction of an electromagnetic shielding building is indispensable. The applicant has already disclosed such an electromagnetic shielding building, for example, in Japanese Patent Publication No. 6-99972 and Japanese Patent Publication No.
Japanese Patent Publication No. 9973, Japanese Patent Publication No. 7-16118, and Japanese Patent Publication No. 6-76706 propose a shielding structure of a building frame and an outer wall. Japanese Patent Publication No. Hei 6-13822 discloses a structure for shielding the entrance and exit of a building.
407, Japanese Patent Publication No. 5-79790, Japanese Patent Publication No. 3
Japanese Patent Application Laid-Open No. 58557/1999 proposes a shielding structure for a window opening. Further, Japanese Patent Publication No. 3-62320, Japanese Patent Publication No. 3-45772, Japanese Patent Publication No. 3-62318, and Japanese Patent Publication No. 5-34159 propose a ceiling and a shielding structure for each layer.

FIG. 2 is a diagram showing an outline of the configuration of an electromagnetic shielding building according to the present invention. The wall is, for example, a sheet using a metal mesh, a metal foil (film), a non-woven fabric, or other conductive fibers on the inner wall of a frame. The electromagnetic shielding layer is formed by applying a conductive paint or the like, or a board using such an electromagnetic shielding layer formed on one side is used. ceiling,
The floor is also constructed in the same manner as the wall or using a panel to which an electromagnetic shielding material is attached. The window forms an electromagnetic shielding film on one or both sides of the window glass using an electromagnetic shielding material in the same manner as described above, and by connecting this electromagnetic shielding film to a sash frame, the electromagnetic shielding layers of the wall and the window are electrically connected. Are connected integrally to each other.

[0004] In this way, the building is not divided into one electromagnetic shielding space, but each floor is partitioned by an electromagnetic shielding material on the upper and lower ceilings and floors, or a wall between rooms is partitioned on each floor by the electromagnetic shielding material. This makes it possible to configure a plurality of independent electromagnetic shielding spaces for each floor or each room.

[0005]

When a high-performance electromagnetic shield is to be achieved, the portion that greatly affects the performance is the window opening. However, the current electromagnetic shield glass is expensive and requires a low-cost construction method. Is required. The conventional method has a problem that the glass tone is inevitably changed to a multi-layer type glass, the groove width of the sash is increased, and the cost is increased. This problem,
In particular, this is a major problem in the case of a renovation in which a building is renovated.

The present invention has been made to solve the above problems, and provides an electromagnetic shielding window which can be applied at a low cost, and which can be applied at a low cost especially in the case of renewal. The purpose is to provide.

[0007]

In order to achieve the above object, the electromagnetic shielding window of the present invention has a conductive film 5 having a high translucency attached to an upper portion 5a of a glass window 1 and an ultraviolet ray to a lower portion 5b. A conductive film to be cut off is attached, and the outer periphery of the conductive film is electrically connected to the sash frame 2 via the conductive gasket 6. In addition, the conductive film 5
The metal tape 4 may be interposed between the outer periphery of the metal tape and the conductive gasket 6. Note that the numbers added to the above configuration are compared with the drawings for easy understanding of the present invention, and the present invention is not limited thereto.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows an electromagnetic shielding window 1 according to the present invention.
It is sectional drawing which shows embodiment.

The glass window 1 is fitted in a sash frame 2 via a setting block 3. A conductive film 5 is adhered to the surface of the glass window 1, and the conductive film 5
Are pressed and electrically connected by a conductive gasket 6, and the conductive gasket 6 is fixed with a sealing material 7. In order to shield high-frequency electromagnetic waves, the conductive gasket 6 is connected to a capacitor. The conductive gasket 6 prevents leakage of electromagnetic waves, prevents contamination of the conductive film 5, and improves durability. In order to further increase the conductivity on the conductive gasket 6, a metal tape 4 may be arranged in a U-shape around the conductive film 5 and pressed with the conductive gasket 5 or a normal gasket. .

In the present invention, the conductive film 5
The upper part 5a is formed of a conductive film having a high translucency, and the lower part 5b is made of an ultraviolet ray cut film. The lower portion of the glass window 1 blocks ultraviolet rays to prevent the adverse effects of the ultraviolet rays.

Although the embodiment of the present invention has been described above, the present invention is not limited to this, and various modifications can be made. For example, in the above embodiment, an example of a single-layer glass is shown as the electromagnetic shielding glass, but the electromagnetic shielding glass may be applied to a double-layer glass.
