The present invention relates to an electromagnetic shielding structure for an outer wall using an improved curtain wall.

[Conventional technology]

Generally, in intelligent buildings, information communication facilities such as complex electronic exchanges and computers are shared to perform information communication with the inside and outside of the building, but with the increasing sense of value for information, diversification of needs, and individualization The amount of information is increasing. Under such circumstances, how to transmit necessary information more quickly at a low cost has become an issue in large-scale buildings. Information networks based on a data highway method using optical fiber cables or coaxial cables have been studied and proposed as solutions to such problems in intelligent buildings.

[Problems to be solved by the invention]

However, in the data highway method that uses optical fiber cables and coaxial cables, the optical fiber cables and coaxial cables must be spread around every corner (each communication device) in the intelligent building, and the construction cost required for cable laying And the construction period will be a problem.

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 one hand, noise radio waves are emitted to the outside, so it is regulated by the Radio Law up to 50 GHz. Then, there arises a problem that the system malfunctions due to an external radio wave, an internal TV intermediate frequency, a radio wave of a wireless microphone, or the like.

Therefore, the applicant of the present application has constructed various types of intelligent buildings that use electromagnetic shielding materials to form the body and openings such as windows and entrances and exits, and have electromagnetic shielding structure for all screws to enable communication inside the building by radio waves. is suggesting. However, even if the outer wall is composed of a curtain wall using an electromagnetic shielding material, the conventional curtain wall has a cushion material (annular ring) made of synthetic resin or the like, which is made of synthetic resin or the like, and is mounted on the upright surface. The curtain wall edge is placed on top, and the anchor bolts are fixed and fastened to the fastener fixed to the body side. Therefore, there is a problem that adjacent curtain walls are not electrically integrated with each other, radio waves leak from the gaps between the curtain walls, and the outer wall as a whole does not form a complete electromagnetic shielding layer.

The present invention is to solve the above problems and to provide an electromagnetic shielding structure for an outer wall using a curtain wall, in which the outer wall using the curtain wall having the same structure as the conventional one can be configured as a complete electromagnetic shielding layer. It is intended to be provided.

[Means for solving problems]

Therefore, the present invention is an electromagnetic shielding structure of an outer wall using a curtain wall that is configured by using an electromagnetic shielding material and is fixed to a frame with an anchor bolt through a metal fastener, and is an electrically conductive structure on the upright of the curtain wall. A cushion material is attached and electrically conductive layers of adjacent curtain walls are electrically connected and integrated via a conductive cushion material, and
It is characterized in that a backup material made of an electromagnetic shielding material is embedded between the curtain walls, and a caulking material is embedded on the backup material.

[Action]

In the electromagnetic shielding structure for the outer wall using the curtain wall of the present invention, a curtain wall having electromagnetic shielding performance is used,
Since a conductive cushion material is attached on the upright of the curtain wall and the conductive layers of the adjacent curtain walls are electrically connected via the conductive cushion material, the curtain wall can be made into a frame with anchor bolts via metal fasteners. By fixing, the adjacent curtain walls can be electrically integrated. In addition, when electrically connecting the conductive layers of the curtain wall through the conductive cushion material, if the conductive cushion material is pasted on the upright without the insulating layer interposed, they are electrically connected as they are. However, when the conductive cushion material is attached via the insulating layer, the conductive cushion material and the anchor bolt may be electrically connected. Therefore, the electromagnetic shielding performance of the entire outer wall can be secured at the same time by the same construction method as the conventional one, that is, the construction method in which the curtain wall is fixed to the metal fastener with the anchor bolt and the outer wall is assembled.

〔Example〕

 Hereinafter, embodiments will be described with reference to the drawings.

FIG. 1 is a diagram showing an embodiment of an electromagnetic shielding structure for an outer wall using a curtain wall according to the present invention. 1 and 9 are PC curtain walls, 2 and 10 are anchor bolts, 3 is a fastener, 4 is an annular shape. A ring, 5 is a backup material, 6 is a caulking material, 7 is a beam steel frame, and 8 is a crossover connecting line.

FIG. 1 shows a cross section of the connection between the upper PC curtain wall 1 and the lower curtain wall 9.
In the outer wall structure using the PC curtain wall shown in FIG. 1, the fastener 3 is fixed to the beam steel frame 7, and the PC curtain wall 1 and 9 are fixed to the fastener 3 with anchor bolts 2 and 10. This PC curtain wall 1, 9
Has an annular ring 4 affixed to the top of the cube, and by fixing the PC curtain walls 1 and 9 to the fastener 3 with anchor bolts 2 and 10, the gap between them is raised to the top of the cube as shown. It is designed to be closed by the wound annular ring 4. Then, the backup material 5 is embedded in the gap close to the outer wall surface, and the caulking material 6 is further embedded on the backup material 5.

The electromagnetic shielding structure of the outer wall using the curtain wall according to the present invention uses an electromagnetic shielding material for the PC curtain walls 1 and 9 and makes the main body an electromagnetic shielding layer, and also uses a conductive cushion material for the annular ring 4. . Furthermore, the annular ring 4
In the case of a PC curtain wall that is attached on top of a cube with an electrically insulating layer sandwiched between them, the PC curtain wall 1 is connected by connecting the annular ring 4 and the anchor bolt 2 with a crossover connecting wire 8. , 9 main body electromagnetic shield layer is electrically integrated with anchor bolts 2, 10 and fasteners 3,
The annular ring 4 is electrically integrated with the anchor bolt 2 by a connecting wire 8. Further, an electromagnetic shielding material is also used for the backup material 5 to form an electrically integrated structure.

Since the annular ring is wound on the upright side of the PC curtain wall, the gap between the left and right PC curtain walls is closed by the annular ring, the backup material, and the caulking material, as shown in Fig. 1. Be integrated into one.

The present invention can be modified in various ways and is not limited to the above-mentioned embodiments. For example, in the above embodiment, the annular ring and the anchor bolt are connected only on the lower side of the curtain wall, but the same connection may be made on the upper side. Further, when the annular ring is attached on the upright without the insulating layer interposed, the connecting connecting wire between the annular ring and the anchor bolt may be omitted.

〔The invention's effect〕

As is clear from the above description, according to the present invention, since the conductive cushion material is used for the annular ring wound on the upright side of the curtain wall, the entire outer wall surface using the curtain wall is used as the electromagnetic shielding layer. Can be configured. Even if an insulating layer is interposed between the conductive cushioning material and the electromagnetic shielding layer of the curtain wall, the conductive cushioning material and the anchor bolt can be connected with a connecting wire to ensure a reliable connection. Therefore, the electromagnetic shielding performance of the outer wall can be secured. Moreover, by connecting the conductive cushion material and the anchor bolt in advance before building the outer wall,
As in the past, the outer wall can be constructed by simply fixing the PC curtain wall to the fastener with anchor bolts, and at the same time the electromagnetic shielding performance can be secured.
