Description

Description: TECHNICAL FIELD The present invention relates to an intelligent building suitable for adopting an information network system using radio waves, in which the entire building has an electromagnetic shield structure, and in particular, window glass. The present invention relates to an electromagnetic shielding method for a glass window which enhances the electromagnetic shielding performance of.

[Conventional technology]

Generally, in intelligent buildings, information communication facilities such as complex electronic exchanges and computers are shared, and information communication with the inside and outside of the building is carried out, but with increasing value sense of information, diversification of information needs, individualization, Providing information more quickly and accurately is one of the major issues in large-scale buildings. In the intelligent building, optical fiber
An information network based on a data highway method using a cable or a coaxial cable has been studied and proposed.

[Problems to be solved by the invention]

However, in the data highway method that uses optical fiber cables and coaxial cables, it is necessary to stretch the optical fiber cables and coaxial cables all over the interior of the intelligent building, which requires extra work time and labor for cable laying. This will be the case.

Also, if radio waves are used for information communication in the building, it is not necessary to lay cables, but in this case, on the other hand, noise radio waves are emitted to the outside, so up to 50 GHz will be regulated by the Radio Law. On the other hand, there arises a problem that the system malfunctions due to external radio waves, internal TV intermediate frequency, radio microphone radio waves, and the like.

Therefore, the applicant of the present application separately constructed an intelligent building that uses electromagnetic shielding members to construct the building and openings such as windows and entrances and exits, and made the entire building an electromagnetic shielding structure to enable communication inside the building by radio waves. is suggesting. In this case, for the windows and entrances and exits of the building, the glass with mesh or the glass with a conductive film attached is used to perform electromagnetic shielding of the entire building.

By the way, in order to secure the electromagnetic shielding performance of the window by using glass with mesh or glass with a conductive film attached, it is necessary to surely ground the mesh and the conductive film. However, since securing the electromagnetic shielding performance in a glass window has not been studied in itself, the technology for grounding the electromagnetic shielding layer of glass has not been established.

The present invention is based on the above consideration, and an object of the present invention is to provide an electromagnetic shielding method for a glass window, which is inexpensive and can easily ground the electromagnetic shielding layer of the window glass.

[Means for solving problems]

Therefore, the present invention is an electromagnetic shielding method for a glass window in an interregent building in which an opening such as a frame and a window or an entrance / exit is formed by using an electromagnetic shield member, and an electromagnetic shield is provided. By applying a conductive paint to the edge of the window glass having the layer and compressing and fixing the conductive rubber between the window glass and the sash, the electromagnetic shielding layer of the window glass and the sash are electrically connected. It is characterized in that it is integrated with and secures conductivity.

[Action]

In the electromagnetic shielding method of the glass window of the present invention, the conductive rubber is compressed to fix the window glass to the sash, so that the window glass and its electromagnetic shield layer and the conductive rubber are disposed between the sash and the conductive rubber. Since a sufficiently large contact pressure can be obtained with, the contact resistance can be lowered, and sufficient conductivity can be secured between the electromagnetic shield layer of the window glass and the sash. Therefore, connect this sash to the earth circuit. It will be good.

In FIG. 1, a window glass 1 has an electromagnetic shield layer 2 made of a conductive member such as a mesh or a film,
A conductive paint is applied to the end portion. The conductive rubber 4 is for fixing the window glass 1 to the conductive sash 5 by compression, and the conductive paint 3 and the conductive rubber 4 allow the conductive shield 3 to conduct between the electromagnetic shield layer 2 of the window glass 1 and the sash 5. Sex is secured. In particular, by compressing and fixing the window glass 1 with the conductive rubber 4, the contact pressure between the conductive paint 3 and the conductive rubber 4 electrically connected to the electromagnetic shield layer 2 becomes sufficiently large, and , Sash 5 as well
Since the contact pressure between the conductive rubber 4 and the
The contact resistance is reduced and sufficient conductivity can be obtained.

The example shown in FIG. 2 is another embodiment of the present invention in which a window glass 6 is vacuum-deposited with a metal or a conductive film is attached to form an electromagnetic shield layer 7. In this case, since the electromagnetic shield layer 7 is present on the surface of the window glass 6, the direct gap between the electromagnetic shield layer 7 and the conductive rubber 4 is not applied even if the conductive paint 3 is not applied as shown in FIG. The conductivity can be ensured.

FIG. 3 is a diagram for explaining one embodiment of a grounding method of a sash frame, 11 is a sash frame, 12 is a sash anchor, 13 is an embedded anchor, 14 is a reinforcing bar, 15 is a mortar,
16 indicates a body.

In FIG. 3, the reinforcing bar 14 is for reinforcing concrete of the frame 16, and is finally grounded through this reinforcing bar 14.
Therefore, the embedded anchor 13 is embedded in the concrete of the skeleton 16 by one shot, and the reinforcing bar 14 and the earth bond are formed in the embedded anchor 13. Therefore, by welding the embedded anchor 13 at one or more locations from the sash frame 11 by welding, the conductivity from the sash frame 11 to the reinforcing bar can be improved, and the electromagnetic shielding performance of the entire window can be enhanced.
