Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a technical field in which a space inside a building is constructed as an electromagnetically shielded space independent from the outside by surrounding the periphery with an electromagnetically shielded layer made of an electromagnetically shielded material.

[0002]

2. Description of the Related Art As office buildings become OA, communication information processing systems using LAN and other communication lines are constructed. However, as the system becomes larger, securing communication lines becomes an issue. If the wiring of cables becomes complicated and complicated with the increase in communication information, the amount of work of wiring change when rearranging rooms or devices increases. Therefore, adoption of a wireless communication system using radio waves has attracted attention as one method.

[0003] However, when a radio communication system using radio waves is adopted, regulations of the Radio Law regarding the frequency band to be used 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 described such an electromagnetically shielded building in, for example, Japanese Patent Publication No. 6-99972, Japanese Patent Publication No. 6-99973, Japanese Patent Publication No. 7-16118, and Japanese Patent Publication No. 6-76706. Proposed outer wall shielding structure, Japanese Patent Publication No. 6-99971, Japanese Patent Publication No. 6-33699, Japanese Patent Publication No. 6-13822.
Japanese Patent Publication No.
-63407, Japanese Patent Publication No. 5-79790, and Japanese Patent Publication No. 3-58557 propose a window opening shielding structure. Further, Japanese Patent Publication No. 3-62320, Japanese Patent Publication No. 3-45972, Japanese Patent Publication No. 3-62318, and Japanese Patent Publication No. 5-34159 propose a ceiling and a shielding structure for each layer.

As seen in these proposals, the electromagnetic shielding building uses an electromagnetic shielding material for a frame and a wall structure, and also uses an electromagnetic shielding material for openings such as windows and entrances along the outer wall of the building. By covering the entire surface with electromagnetic shielding material,
The space in the building can be configured as one electromagnetic shield space independent of the outside. Further, instead of using one electromagnetic shielded space in the building, the floors and ceilings on each floor are separated by electromagnetic shields, or the walls between rooms are separated by electromagnetic shields on each floor. Alternatively, a plurality of independent electromagnetic shielded spaces can be configured for each room.

[0005]

However, since the above-mentioned conventional electromagnetic shielding technology is mainly applied to a newly built building, an existing building having no electromagnetic shielding performance is used as an electromagnetic shielding building. , When building an independent electromagnetic shielded space for each floor or each room (hereinafter referred to as "renewal"), the frame or mist,
Since the structure of the building such as walls and slabs must be put into the hands, the construction work becomes large and it is not realistic in terms of cost and construction period. Therefore, in the case of renewal, new measures for constructing the electromagnetically shielded space are required.

In the renewal, providing the electromagnetic shielding material on the wall, the ceiling, the glass window, and the floor itself is performed by providing the electromagnetic shielding material such as the metal mesh, the metal foil, the conductive fiber sheet and the conductive paint on the inner surface thereof. It can be realized relatively easily, but the connection between the electromagnetic shields, especially along the window, a window member such as a fan coil unit or a decorative panel is provided, and when this window member is attached to the sash frame of the window, There is a problem that it is difficult to connect the electromagnetic shielding material between the window and the wall.

[0007] The present invention is to solve the above-mentioned problems, and an object of the present invention is to provide an electromagnetic shielding building capable of performing electromagnetic shielding with low cost and simple construction as a part of such renewal measures. And

[0008]

To this end, the electromagnetic shielding building of the present invention is an electromagnetic shielding building in which the entire inner space of the building is covered with an electromagnetic shielding material and electrically connected, and a metal fixed to a window portion. Made sash frame, an electromagnetic shield provided in the window portion and electrically connected to the sash frame, a vertical support wall formed on the indoor side of the sash frame, and formed horizontally on the support wall. A plurality of reinforcing ribs and a window member attached to the supporting wall, a conductive backup material is filled between the reinforcing ribs, and a metal is provided between the reinforcing ribs and the electromagnetic shielding material of the outer wall. It is characterized in that a connection member made of metal is fixed.

Embodiments of the present invention will be described below with reference to the drawings. 1 and 2 show one embodiment of an electromagnetic shielding building of the present invention, FIG. 1 is an enlarged sectional view, and FIG. 2 is a sectional view showing the entire structure.

In FIG. 2, a ceiling slab 1, a floor slab 2, an inner wall 3, an outer wall 4, a window portion 5 and a ceiling 6 constitute an existing frame having no electromagnetic shielding performance and are surrounded by these. In order to make the internal space R an electromagnetically shielded space,
Due to the renewal, the electromagnetic shield 7 is provided inside the inner wall 3 and the outer wall 4, the electromagnetic shield 8 is provided on the lower surface of the ceiling slab 1, and the electromagnetic shield 9 is provided on the window 5. Each electromagnetic shielding material 7, 8, 9 is formed by sticking a sheet using a metal mesh, a metal foil, or a conductive fiber or applying a conductive paint, and each electromagnetic shielding material 7, 8, 9 is formed. There is an electrical connection between them.

Regarding the floor, the existing tile carpet 1

As a result, the electromagnetic shielding material covers all six surfaces of the ceiling, the floor, and the surrounding walls, and an electromagnetic shielding space R independent from the outside is constructed. A window member 13 such as a fan coil unit or a decorative panel is provided along the window 5.

Next, the connection of the electromagnetic shields 9 and 7 between the window 5 and the outer wall 4, which is a feature of the present invention, will be described with reference to FIG. In the existing window portion 5, a sash frame 15 made of metal such as aluminum is fixed to the outer wall 4. A vertical support wall 15a is formed on the indoor side of the sash frame 15, and a plurality of reinforcing ribs 15b are horizontally formed on the support wall 15a.
A window member 13 such as a fan coil unit or a decorative panel is attached to the support wall 15a.

In order to make this window portion 5 an electromagnetic shield structure by renewal, a window glass 5a having an electromagnetic shield material 9 is fitted in the sash frame 15, and the electromagnetic shield material 9 is made of a conductive backup material 5b and a ground electrode 5c. Sash frame 15

A metallic connecting member 20 is fixed between the reinforcing rib 15b and the electromagnetic shield 7 by means of screws. Therefore, even if the sash frame 15 has the reinforcing rib 15b having a complicated shape, the electromagnetic shield 9 of the window 5 can be electrically connected to the electromagnetic shield 7 of the outer wall 4.

Note that the present invention is not limited to the above example, and various modifications are possible. For example, in the above example, the case where an existing building having no electromagnetic shielding performance is renewed as an electromagnetic shielding building has been described, but a newly constructed building may be similarly configured.
