Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an intelligent building having an electromagnetic shielding structure suitable for adopting an information network system using radio waves, and more particularly to an electromagnetic shielding at a window opening. It relates to an electromagnetic shielding window to be performed.

[Prior art] In general, in an intelligent building, information communication with the inside and outside of the building is performed jointly by using information communication equipment such as a complex electronic exchange and a computer. The amount of information is increasing with individualization. Under such circumstances, it is an issue in large-scale buildings how to transmit necessary information more quickly at a lower cost. To respond to such issues in intelligent buildings,
An information network using a data highway method using optical fiber cables and coaxial cables has been studied.
Proposed.

[Problems to be Solved by the Invention] However, in the data highway system using an optical fiber cable or a coaxial cable, the optical fiber cable or the coaxial cable must be stretched to every corner in the intelligent building, so that the cable laying is difficult. Therefore, floor ducts and double floors are required, and construction costs and construction periods cannot be ignored.

If radio waves are used for information communication in the building, there is no need to lay cables, but in this case, as shown in Fig. 4, on the other hand, noise waves are emitted to the outside. On the other hand, there is a problem that the system malfunctions due to external radio waves or the like.

Therefore, we proposed a proposal for an intelligent building that enabled wireless communication in the building by radio waves by making the entire building an electromagnetic shielding structure using electromagnetic shielding materials for the applicant, the building, windows and entrances and other openings. Is going.

In that case, in an intelligent building having a radio wave shielding structure, various measures and countermeasures are required particularly for windows and entrances that become openings of the building. For example, in the window 1, the electromagnetic shielding performance of the window 1 is secured by using an electromagnetic shielding window glass 2 provided with a mesh or other conductive material as shown in FIG. That is, the electromagnetic shielding glass 2 prevents radio waves from passing through the window 1.

By the way, from the design point of view, recently, as shown in FIG. 6, the electromagnetic glazing window 1 often employs a structural glazing system (SSG) construction method. 3 (two window glasses in the illustrated example) are often arranged side by side on substantially the same plane. In this case, the joint ends 2a, 3a of the electromagnetically shielded window glasses 2, 3 adjacent to each other are supported on the cubic portion 5 of the building via the backup material 4, and the joint between the cubic portion 5 and the electromagnetically shielded window glass 2, 3 End 2a,
3a is hermetically sealed with structural sealants 6 and 7.

However, since these structural sealants 6 and 7 do not have electromagnetic shielding performance, they are located between the joint ends 2a and 3a of the electromagnetic shielding window glass 2 and 3 and between the electromagnetic shielding window glass 2 and 3 and the cubic portion 5.
There is a gap between the building and the building that does not have electromagnetic shielding performance.
Conversely, it passes from inside to outside. Therefore,
As described above, there is a problem that even if the window glasses 2 and 3 have the electromagnetic shielding performance, the window 1 cannot reliably shield the electromagnetic waves.

The present invention has been made in view of such a problem, and an object of the present invention is to provide an electromagnetic shielding window that can reliably shield electromagnetic waves even at a joint portion of the electromagnetic shielding window glass.

[Means for Solving the Problems] In order to solve the above-mentioned problems, the present invention provides a plurality of electromagnetic shielding windowpanes arranged side by side on the same plane and the electromagnetic shielding windowpanes adjacent to each other. An electromagnetic shielding window in which a joint end is supported by a cubic portion via a backup material and a gap between the cubic portion and a joint end of the electromagnetic shielding window glass is sealed and adhered by a structural sealant, wherein the structural sealant is provided. Is a conductive sealant that electrically connects the conductive member provided on the cubic portion and grounded to the electromagnetic shielding member of the electromagnetic shielding window glass.

[Operation] In the electromagnetic shielding window according to the present invention having such a configuration, the conductive structural sealant is provided between the conductive member provided on the cubic portion and grounded and the electromagnetic shielding member of the electromagnetic shielding window glass. Since it is sealed and electrically connected, the joint part of the electromagnetic shielding window glass has an electromagnetic shielding structure. Therefore, even at the joint part of the window glass, the electromagnetic wave is reliably shielded.

Further, the conductive sealant of the present invention can be formed by imparting electromagnetic shielding performance to a conventional structural sealant. Therefore, the space between the cubic portion and the joint end of the electromagnetic shielding window glass can be sealed and bonded without using a special electromagnetic shielding member, and it can be easily adapted to windows of an existing building at low cost. become able to.

Embodiment An embodiment of the present invention will be described below with reference to the drawings. In the following embodiments, the same components as those in the above-described conventional example are denoted by the same reference numerals, and detailed description thereof will be omitted.

FIG. 1 is a partial sectional view of an embodiment of the electromagnetic shielding window according to the present invention.

As shown in Fig. 1, electromagnetic shielding window 1 by SSG construction method
Is provided with two electromagnetically shielded window glasses 2 and 3. Electromagnetic shielding members 8, 9 are disposed on the indoor side surfaces of the electromagnetic shielding window glasses 2, 3. Further, joint ends 2a, 3a of the electromagnetic shielding window glass 2, 3 are supported by a cubic portion 5 of a building via a backup material 4, and the cubic portion 5 and the electromagnetic shielding glazing are connected to each other.
A couple of joint ends 2a and 3a are hermetically fixed by structural seals 6 'and 7'. Further, a sealing material 10 for waterproofing is filled and sealed between the joint ends 2a and 3a.

On the other hand, the structural sealants 6 'and 7' contain a conductive material and are considered to be high modulus conductive sealants. These structural sealants 6 ′ and 7 ′ are electrically connected to each other using the electromagnetic shielding members 8 and 9 of the window glasses 2 and 3 and the metal sash of the cubic portion 5.

Therefore, if the electromagnetic wave α tries to leak from the room to the outside through the window glass 2, 3, the electromagnetic wave α
It strikes a few electromagnetic shielding members 8, 9 and its electromagnetic energy is transmitted to the cubicle 5 through conductive structural sealants 6 ', 7'. Therefore, the electromagnetic wave α is prevented from leaking out through the window. In addition, the electromagnetic wave α
When the electromagnetic wave α collides with the structural sealants 6 ′ and 7 ′, the energy is similarly transmitted to the cubic portion 5, and the electromagnetic wave α is transmitted to the joint portion 2 a. Leakage to the outside through the gap is also prevented. Conversely, the electromagnetic wave β from the outside is prevented from entering the room through the gaps between the window glasses 2 and 3 and the joint.

FIG. 2 is a sectional view similar to FIG. 1 showing another embodiment of the present invention.

In this embodiment, the electromagnetic shielding window glasses 2 and 3 are formed of multiple layers (two layers in the illustrated example) of glass,
Electromagnetic shielding members 8, 9 are arranged on the air-sealed side surface of the glass on the indoor side. Also, three backup materials 4, 4, 4 made of foamed polyethylene or the like are provided as backup materials. Further, a layer of metal foil or a layer 12 of, for example, an epoxy-based conductive paint is provided from the opposing surfaces of the joint ends 2a, 3a of the window glasses 2, 3 to the indoor side surface. This layer
Reference numeral 12 is connected to the electromagnetic shielding members 8, 9 and to the structural sealants 6 ', 7'.

Therefore, in this embodiment, when the electromagnetic wave α collides with the electromagnetic shielding members 8 and 9 of the window glasses 2 and 3, the energy is transferred to a metal foil layer or a layer of, for example, an epoxy-based conductive paint.
It flows into the cubicle 5 through 12 and the structural sealants 6 ', 7'. Further, the electromagnetic wave α that is going to pass through the gap between the joint ends 2a, 3a and the cubic portion 5 is the same as that described above, and will not be described. In this way, the gaps between the windowpanes 2, 3 and the joint ends 2a, 3a and the cubic portion 5 are electromagnetically shielded.

FIG. 3 is a partial sectional view similar to FIG. 1 showing still another embodiment of the present invention.

In this embodiment, the electromagnetic shielding window glasses 2 and 3 are formed of laminated glass, and electromagnetic shielding members 8 and 9 are disposed between the inner and outer glasses. Other configurations are the same as those of the embodiment shown in FIG.

Therefore, also in this embodiment, the joint portions of the window glasses 2 and 3 have an electromagnetic shielding structure.

[Effects of the Invention] As is clear from the above description, according to the electromagnetic shielding window of the present invention, not only can the electromagnetic shielding window glass reliably shield electromagnetic waves, but also at the joint portion of the window glass, Electromagnetic waves can be reliably shielded.

Further, by using a conductive sealant as the structural sealant, the conventional structural sealant can be provided with electromagnetic shielding performance. Therefore, the space between the cubic portion and the joint end of the electromagnetic shielding window glass can be sealed and bonded without using a special electromagnetic shielding member, and it can be easily adapted to windows of an existing building at low cost. An electromagnetic shielding structure can be provided.
