The present invention relates to a waist structure of a type electromagnetic wave shielding curtain wall.

2. Description of the Related Art In the modern information society, various radio waves, such as the Internet, mobile phones, BS broadcasts, digital broadcasts, and radio waves, fly through space. The use of such radio waves is expected to increase further in the future.

However, this has the following adverse effects at the same time. For example, when a computer system device, an OA device, or the like that supports advanced information is installed inside a building, radio waves from outside the building may cause problems such as malfunction and data loss. When an extension telephone based on the PHS system or the wireless system is constructed in a building instead of a conventional wired extension telephone, communication may be affected by an external radio wave. A similar possibility exists in places where sound and image radio waves fly, such as in theaters and studios. Further, if highly confidential information is scattered as radio waves inside the building, such information may leak to the outside of the building, causing a problem that confidentiality cannot be maintained.

Therefore, in order to solve such a problem,
It becomes necessary to make the interior of the building an electromagnetic wave shielding space. As a method of making the interior of a building an electromagnetic wave shielding space, there is known a method of covering a floor, a wall, a ceiling, etc., of all six surfaces with a conductive member, and grounding them on a certain floor of the building. ing.

[0005]

However, this method is to be referred to as an interior type electromagnetic wave shielding method. In the treatment of the wall surface, the inner wall provided inside the outer wall or the outer wall is provided. It is necessary to manually attach the electromagnetic wave shielding material to the inner surface with an adhesive or metal, and connect the electromagnetic wave shielding material attached to the wall surface to the electromagnetic wave shielding material attached to the floor. further,
The electromagnetic wave shielding material to be attached to the floor needs to be attached by an operator to a portion other than the floor, for example, a steel frame stair.

[0006] Therefore, the cost is increased and the construction period is lengthened, which imposes a heavy burden on making each floor of the building an electromagnetic wave shielding space. In addition, since this method requires renovation of the inner wall, when the interior of an existing building is used as an electromagnetic shielding space, it cannot be renovated while using the interior, and hesitates to start the renovation itself There is also a problem.

[0007] Therefore, a first object of the present invention is to provide an electromagnetic wave shielding space not for each individual space, but for an exterior type instead of an interior type, so that at least a plurality of buildings or a multi-storey building can be constructed. An object of the present invention is to enable the entire floor to be constructed as an exterior electromagnetic shielding space, thereby reducing costs and shortening the construction period.

[0008] A second problem is that the structure of the outer wall portion is devised in order to secure conductivity, and that the construction can be performed easily and with excellent workability.

[0009] Other problems will be clarified in relation to the functions and effects described later.

[0010]

Then, the electromagnetic wave shielding material 2 is directly attached to the base material, and the waterproof layer and the pressing concrete 17 are provided thereon.

In either case of the outside roof roof slab insulation method and the inside roof roof slab insulation method, the pressing concrete 17
It is conceivable to attach the electromagnetic wave shielding material 2 on the upper surface of the substrate, but this method requires some protection material on the upper portion in terms of weather resistance. In addition, if it is based on the exposure waterproofing without the holding concrete 17, the roof slab 12c is directly
The electromagnetic wave shielding material 2 is adhered, and an exposure waterproofing process is performed thereon.

On the other hand, when a bent plate type is used as the metal panel 1, as shown in FIG. 19, a seal is provided between joints between the metal panel 1 bent into a lunch box shape and the glass support frame 4. A material 43 and a conductive backer material 41 are provided, and a conductive gasket 45 is provided at the joint bottom. The effect of this is
This is similar to the case where a cut-plate type is used as the metal panel 1.

<Connection between Glass Support Member and Electromagnetic Shield Glass> The glass support frame 4 connected to the metal panel 1 in this way is further connected to the electromagnetic shield glass 5.

First, when the glass supporting structure is of a dry type, as shown in FIG. 32, a conductive sheet 44 is provided at the floor side end of the electromagnetic wave shielding glass 5 and a conductive gasket 45 is provided outside the building room. Thus, the electromagnetic shield glass 5 and the glass support frame 4 are electrically connected to the conductive sheet 44 and the conductive gasket 45. In addition, the conductive gasket 45 ensures watertightness.

On the other hand, when the glass supporting structure is a wet type, as shown in FIGS. 33 and 34, a conductive sheet 44 is provided on the floor side end of the electromagnetic wave shielding glass 5 and a conductive gasket spacer 46 is provided on the outside of the building room.

The electromagnetic wave shielding glass 5 used in the above is a double-layer glass in which a metal film exhibiting electromagnetic wave shielding properties is applied to the outdoor surface of the inner glass, the indoor surface of the outer glass, or each of these surfaces. Examples thereof include an intermediate layer of laminated glass with an electromagnetic wave shielding sheet sandwiched therebetween, and a general glass provided with an electromagnetic wave shielding film on the indoor surface, but are not limited to these examples.

<Method of Using Glass Curtain Wall as Outer Wall> The case where a metal panel is attached to the outer wall has been described above. In addition, it is considered that a curtain wall made of electromagnetic shielding glass is used as the outer wall. Can be

In this case, the work on the side of the building is as shown in FIG.
As shown in FIG. 5 and FIG.

Between the joint 7 and the conductive gasket 4 with airtightness
5, 45, 45 are provided.

<Structure Attached as Single Window> Further, an opening can be provided in the conductive metal panel, and the window can be formed by the glass support frame and the electromagnetic wave shielding glass 5. In this case, as shown in FIGS. 39 and 40, a seal material 41 and a conductive backer material 43 are provided between joints between the metal panel 16 and the metal glass support frame 4. Thereby, the metal panel 16
And the glass support frame 4 are electrically connected.

The glass support frame 4 is electrically connected to the electromagnetic shield glass 5 by a conductive gasket 45 for fixing the electromagnetic shield glass 5.

<Method of Parallel Window> The electromagnetic shielding glass used in the above has an electromagnetic shielding property of 4
Although it is necessary to have a high performance of 0 db or more, a case where the electromagnetic wave shielding property is a low performance of about 25 db to 30 db will be described below.

In this case, as shown in FIGS. 41 and 42, the electromagnetic shielding performance is improved by installing two low-performance electromagnetic shielding glasses 31 in parallel. A conductive gasket 4 is provided between the electromagnetic wave shielding surfaces 31a, 31a provided on the low-performance electromagnetic wave shielding glasses 31, 31 and the joint of the metal glass support frame 4 and the shoji frame 22.

In this case, the low-performance electromagnetic wave shielding glass 31 on the indoor side is a one-way opening type for maintenance.
Alternatively, it is recommended to use an open / close type such as an inner lift type. As the method, low performance electromagnetic wave shielding glass 3
A conductive gasket 45 having airtight performance is provided between joints between the electromagnetic wave shielding processing surface 31a and the shoji frame 22 provided in 1. Thereby, the low-performance electromagnetic shielding glass 3
1 and the shoji frame 22 are electrically connected. The shoji frame 22 is also electrically connected to the lower frame 26 and the vertical frame 24 by the conductive gasket 45.

At present, the electromagnetic wave shielding property is 40d.
Electromagnetic shielding glass with a high performance of b or more is very expensive due to the complexity of the manufacturing process. Therefore, if low-performance electromagnetic wave shielding glasses are installed in parallel at a certain distance as in the present embodiment, it is possible to secure an electromagnetic wave shielding property of 40 db or more at low cost. In addition, by installing the blinds 32 inside, it is possible to reduce the load on the window space such as an office or a hospital. Furthermore, since the glass is installed in two layers, a sound insulation effect can be expected.

<Method of Making Outer Wall Structure Fire-Resistant> When the outer wall structure is made of fire-resistant type, the glass provided in the opening can be made of general glass 33 as shown in FIGS. 43 and 44. In this case, a metal panel 1 made of aluminum, steel, stainless steel, or the like is attached to a refractory material 34 made of a calcium silicate plate, rock wool, or the like.
The electromagnetic wave shield panel is electrically connected to the cubic 27 and the blanks 23 by the conductive gasket 45.

FIG. 4 shows the electromagnetic wave shielding panel.
As shown in FIG. 5 and FIG. 46, a refractory material having a surface to which an electromagnetic wave shielding sheet 29 and an electromagnetic wave shielding tape 30 are adhered may be used.

<Aluminum Window Frame> As shown in FIG. 26, an aluminum glass support member used in the present embodiment is provided in parallel with the electromagnetic wave shielding glass at the portion where the electromagnetic wave shielding glass is fitted along the longitudinal direction of the mold. The stripped portions 35 are formed by forming the thin portions 35A, 35A of the strips, and the alumite film (bake coating may be applied) on the surface of the glass support frame 4.
And the like. However, since an alumite film is not generated in the hollow portion during the surface treatment, when the peeling portion 35 of the glass support frame 4 is peeled off during use, a high electric conduction surface 36 close to an aluminum base is generated. The stripping portion 35 is preferably provided at a portion where the conductive gasket is fitted as shown in FIG. 27, and at a portion where the electromagnetic wave shielding material is fitted as shown in FIG.

When the electromagnetic wave shielding glass is fitted into the glass support frame 4 shown in FIG. 26, as shown in FIG. 29, a conductive sheet 44 is provided at the end of the electromagnetic wave shielding glass 5 on the floor side. A conductive gasket 45 is provided between 44 and the glass support frame 4. As a result, the electromagnetic wave shielding glass 5 and the glass support frame 4 are electrically connected by the conductive sheet 44, the conductive gasket 45, and the highly conductive surface 36 near the base of the aluminum frame. When the electromagnetic shielding glass is embedded in the glass supporting frame 4 shown in FIG. 27, the electromagnetic shielding glass 5 and the glass supporting frame 4 are connected to each other at the floor side end of the electromagnetic shielding glass 5 as shown in FIG. Conductive sheet 44, conductive gasket 45, and high electrical conduction surface 36 close to the base of aluminum frame

As shown in FIG. 23, the end portion of the gasket, which is connected at the site, has a concave shape and a convex shape made of a conductive material such as conductive silicon. After the connection, as shown in FIG. The ends of the two gaskets are fitted and integrated. FIG. 25 shows this conductive gasket 45.
