Description

  The present invention relates to an exterior type electromagnetic shield building.

In the modern information society, various radio waves such as the Internet, mobile phones, BS broadcasts, digital broadcasts, and radio waves fly around the space. The use of such radio waves is expected to increase further in the future.
However, this also has the following adverse effects. For example, when a computer system device or OA device that supports advanced information is installed inside a building, problems such as malfunction and data loss may occur due to radio waves from outside the building. When building a PHS or wireless extension telephone in a building instead of a conventional wired extension telephone, communication may be affected by external radio waves. There is a similar possibility in places where sound and radio waves fly like theaters and studios. Furthermore, if very sensitive information is made to fly around in the building as radio waves, such information may leak outside the building, and there is a possibility that the confidentiality cannot be maintained.
Therefore, in order to solve such problems, it is necessary to make the inside of the building an electromagnetic shielding space. As a method of making the inside of a building an electromagnetic shielding space, a method is known in which all six surfaces such as a floor, a wall, a ceiling, etc. are covered with a conductive member for grounding a building and grounded. ing.

However, this method should be referred to as an interior-type electromagnetic shielding method. In the treatment of the wall surface, an electromagnetic shielding material is bonded to the inner wall that is additionally provided inside the outer wall or to the inner surface of the outer wall. An operation is required in which the electromagnetic wave shielding material affixed to the wall surface is connected to the electromagnetic wave shielding material affixed to the floor by human affixing with an agent or hardware. Furthermore, the electromagnetic 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 staircase.
Therefore, the cost is high and the construction period is long, which is a great burden on making all the floors of the construction into an electromagnetic shielding space. In addition, this method requires renovation of the inner wall, so when the interior of an existing building is used as an electromagnetic shielding space, it cannot be refurbished while using the interior, and it is reluctant to start renovation itself. There is also a problem.
Therefore, the first problem of the present invention is not to constitute an electromagnetic shielding space for each individual space, but also to an exterior type rather than an interior type, so that the entire building or at least a plurality of floors of a hierarchical building It can be constructed as an exterior type electromagnetic shielding space, and the cost can be reduced and the construction period can be shortened.
Other issues will be clarified in relation to the effects described below.

The present invention that has solved the above problems is as follows.
In the outer wall of the curtain wall structure of the building,
The outer wall of the curtain wall structure has a conductive frame member as a supporting member, and an exterior surface is formed by a conductive metal panel, a conductive aluminum window frame, and an electromagnetic wave shielding glass provided in the window frame opening,
On the exterior surface of the target electromagnetic wave shield height range, the conductive metal panel, the conductive window frame, and the electromagnetic wave shield glass are connected in a conductive state to form an electromagnetic wave shield external surface, and the electromagnetic wave shield external surface is an electromagnetic wave shield. An exterior type electromagnetic shielding structure characterized in that it constitutes the wall of the space.

(Functions and effects of claims 1 to 3)
In the conventional example, as shown in FIG. 47, the electromagnetic wave shielding material 2 is attached to the floor slab 12a, the ceiling slab 12b, and the inner surface of the outer wall individually for the floor as the electromagnetic wave shielding space.
However, in the present invention, as illustrated in FIG. 3, the entire exterior surface of a building (including a hierarchical building) or the exterior surface of a necessary layer is made conductive to constitute the wall surface of the electromagnetic wave shield space. The installation area of the electromagnetic shielding material 2 is greatly reduced, the amount of the electromagnetic shielding material 2 used is reduced, and the construction period is shortened, so that the cost is remarkably reduced. In addition, in the case of renovation, renovation is possible without hindering residence and work in each floor.
Further, when forming the exterior surface, the outer wall of the curtain wall structure is used, the conductive frame member is used as a support member, the conductive metal panel, the conductive aluminum window frame, and the electromagnetic wave shielding glass provided in the window frame opening. A configuration form is provided. However, when the constituent members of these exterior surfaces are connected in a conductive state, an electromagnetic wave shielding surface can be obtained.
Conventionally, even if an electromagnetic wave shielding glass is provided, the aluminum window frame with an anodized coating has a fixed idea that it has no electrical conductivity. Glass was connected to an electromagnetic shielding material in which a conductive band material or sheet material was laid on the floor without interposing a window frame or a metal panel. Therefore, the electromagnetic wave shielding glass is required to be fixed.
Compared to this conventional example, an aluminum window frame or opening frame with an alumite film, a conductive metal panel, an electromagnetic shielding glass or a conductive face plate, a conductive sealing material, a conductive backer, a conductive gasket. It has been found that even when assembled with a normal outer wall construction using a connecting material such as the above, it has satisfactory electromagnetic shielding performance.
For this reason, even if the conductive band material or sheet material is connected to the electromagnetic shielding material laid on the floor, if the electromagnetic shielding material laid on the floor is connected in a conductive state with a component on the exterior surface, the conductive band material Alternatively, the sheet material can be made inconspicuous from the room.

<Outline for making electromagnetic shielding space>
In the embodiment, as shown in FIG. 1 and FIG. 3, the entire interior of the building is used as an electromagnetic shielding space, or as shown in FIG. 2, FIG. 5, and FIG. Then, the case where the 2nd to 4th floors are used as electromagnetic shielding spaces) can be used as the electromagnetic shielding space. And the form made into an electromagnetic wave shield space in this way can be applied when renovating an existing building or when building a new building. The building structure may be steel or concrete. In the figure, 3 is an electromagnetic shielding glass window, and 1 is a conductive metal panel portion.
FIG. 5 shows a case where a predetermined predetermined floor of a steel building is used as an electromagnetic shielding space, and FIG. 6 shows a case where a predetermined predetermined floor of a concrete building is used as an electromagnetic shielding space. When the predetermined predetermined floor is used as the electromagnetic shielding space, the electromagnetic shielding material 2 is attached to the floor slab 12a on the lowermost floor and the ceiling slab 12b on the uppermost floor, and attached to the outer wall, in addition to the work on the outer wall. It is sufficient to electrically connect the member, the conductive metal panel 1, the window frame, and the electromagnetic wave shielding glass 3. However, when building a new building and the floor to be used as an electromagnetic shielding space is not determined, an electromagnetic shielding material can be attached to all floor slabs and roof slabs to facilitate later work.

<Working on the outer wall with an opening>
When the building outer wall is provided with the opening 3 as shown in FIG. 1 and FIG. 2, as the work on the side of the building, as shown in FIGS. 7 and 20, the outer wall of the building is replaced with the metal panel 1 for curtain wall. A metal glass support frame 4 is attached to the opening 3 provided on the outer wall to cover, and an electromagnetic wave shielding glass 5 is attached to the glass support frame 4.
This work is no different with or without existing buildings, new buildings or exterior walls. However, when a metal panel or the like is already used for an existing building, the existing metal panel may be used.

<Connection between metal panel / glass support member and electromagnetic shielding material>
And the said metal panel 1 and the said glass support frame 4 and the said electromagnetic wave shielding material 2 are attached as follows.
First, when the building is a steel structure, as shown in FIGS. 7 and 9, the electromagnetic wave shielding material 2 is the floor slab 12a (the ceiling slab is the same as the floor slab except for the roof. The deck plate 13 provided in the section is used later). The deck plate 13 is electrically connected to the metal panel 1 and the glass support frame 4 through the concrete stopper 14 and the conductor 20. In this regard, the conductor 20 may be configured to be connected to the deck plate 13 in the middle of the floor slab 12a as shown in FIG. 8, but this method requires that the floor slab 12a be cut in the middle. Resulting in structural difficulties. Therefore, the form using the concrete stopper 14 is desirable.
On the other hand, when the building is made of concrete, as shown in FIGS. 10 and 20, the electromagnetic shielding material 2 is attached to the surface of the floor slab 12 a, and the electromagnetic shielding material 2 is connected to the metal panel 1 via the conductor 20. -It is electrically connected to the glass support frame 4.
In this case, a metal sheet, a metal nonwoven fabric, or the like can be used as the electromagnetic shielding material 2, and a metal mesh, a metal film, a metal nonwoven fabric, or the like can be used as the conductor 20.

<Working on the roof>
On the other hand, when the top floor of the building is included as a floor serving as an electromagnetic shielding space, the following work is performed as work on the roof slab, unlike the work on the floor slab or ceiling slab.
In particular, in the present embodiment, first, as shown in FIGS. 11, 12, and 21, in addition to the metal panel 1 and the electromagnetic shielding material 2, a case where a rooftop parapet conductive metal headboard 15 is used is shown. . In this case, a conductive joint material 6 is provided between the joints of the metal panel 1 and the rooftop parapet metal headboard 15 and between the joints of the rooftop parapet metal headboard 15 and the electromagnetic shielding material 2, respectively. Connecting.
FIG. 11 and FIG. 21 correspond to the roof slab outer heat insulating method, and is a case where the heat insulating layer 18 is provided directly on the roof slab 12c. In this case, when the building is a steel structure (FIG. 11) or a concrete structure (FIG. 21), the electromagnetic wave shielding material 2 is pasted on the heat insulating layer 18 in both cases, and the waterproof layer and the pressing concrete are formed thereon. 17 will be provided.
On the other hand, FIG. 12 corresponds to the heat insulation method in the roof slab, and is a case where the heat insulating layer 18 is provided directly under the roof slab 12c. In this case, the electromagnetic wave shielding material 2 is directly attached to the roof slab 12c, and the waterproof layer and the pressing concrete 17 are provided thereon.
In either case of the heat insulation method outside the roof slab or the heat insulation method inside the roof slab, it is conceivable that the electromagnetic wave shielding material 2 is pasted on the holding concrete 17. Necessary. Moreover, if it is based on exposure waterproofing which does not provide the pressing concrete 17, the electromagnetic wave shielding material 2 will be affixed directly on the roof slab 12c, and exposure waterproofing processing will be performed on it.
In addition to the above, various forms of rooftop work are conceivable. For example, as shown in FIG. 13, when the steel roof is the folded plate 19, the folded plate 19 and the rooftop parapet A conductive joint material 6 is provided between joints with the metal headboard 15 and is electrically connected.
As the joint material 6 used above, there is a silicon sealing mixed with conductive carbon, a silicon gasket having conductivity, a backer including a metal mesh, a metal film, a metal nonwoven fabric, or the like.

<Connection between metal panels>
By the way, since it is difficult for the metal panel 1 to cover the entire outer wall with a single sheet, in practice, a plurality of sheets are connected to cover the entire building outer wall.
Thus, the method of connecting the metal panels 1 is as follows. First, when using a cut-panel type metal panel 1, as shown in FIGS. A four-sided frame 21, 21 is attached, and a seal material 41, a conductive backer material 43, and a conductive gasket 45 are provided between the joints of the metal four-sided frames 21, 21. Thereby, the metal panels 1 and 1 are electrically connected. Further, the sealing material 41 and the conductive backer material 43 ensure water tightness, and the conductive gasket 45 ensures air tightness.
On the other hand, when using a bent plate type as the metal panel 1, as shown in FIGS. 17 and 18, the sealing material 41 and the conductive material between the joints of the metal panels 1 and 1 bent into a lunch box shape are used. The backer material 43 is provided with a conductive gasket 45 on the joint bottom. The effect by this is the same as the case where a cut-panel type metal panel 1 is used.

<Connection between metal panel and glass support member>
The metal panel 1 thus electrically connected is further connected to the glass support frame 4 provided in the opening as follows.
First, when using a cut plate type as the metal panel 1, as shown in FIG. 16, a metal four-sided frame 21 is attached to the metal panel 1, and the joint between the metal four-sided frame 21 and the glass support frame 4. Are provided with a sealing material 41, a conductive backer material 43, and a conductive gasket 45. Thereby, the metal panel 1 and the glass support frame 4 are electrically connected. Further, the sealing material 41 and the conductive backer material 43 ensure water tightness, and the conductive gasket 45 ensures air tightness.
On the other hand, when using a bent plate type as the metal panel 1, as shown in FIG. 19, between the joint between the metal panel 1 bent into a lunch box shape and the glass support frame 4, the sealing material 41 and The conductive backer material 43 is provided with a conductive gasket 45 on the joint floor. The effect by this is the same as the case where a cut-panel type metal panel 1 is used.

<Connection between glass support member and electromagnetic shielding glass>
In this way, the glass support frame 4 connected to the metal panel 1 is further connected to the electromagnetic wave shielding glass 5.
First, when the glass support 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. Thereby, the electromagnetic shielding glass 5 and the glass support frame 4 are electrically connected via the conductive sheet 44 and the conductive gasket 45. Further, the watertightness is ensured by the conductive gasket 45.
On the other hand, when the glass support structure is wet, as shown in FIGS. 33 and 34, a conductive sheet 44 is provided at the floor side end of the electromagnetic wave shielding glass 5, and a conductive gasket spacer 46 is provided outside the building room. Thereby, the electromagnetic shielding glass 5 and the glass support frame 4 are electrically connected through the conductive sheet 44 and the conductive gasket spacer 46.
As the electromagnetic wave shielding glass 5 used above, in the multi-layer glass, the inner surface of the inner glass, the inner surface of the outer glass, or each of these surfaces provided with a metal film exhibiting electromagnetic shielding properties, laminated glass Examples include those in which an electromagnetic wave shielding sheet is sandwiched between intermediate layers, and those in which an electromagnetic wave shielding film is provided on the indoor surface of general glass, but are not limited to these examples.

<Method of using glass curtain wall as outer wall>
Although the case where a metal panel is attached to the outer wall has been described above, it is possible to use a curtain wall made of electromagnetic wave shielding glass as the outer wall.
In this case, as the work on the side of the building, as shown in FIGS. 35 and 36, the electromagnetic wave shielding glass 5 is fixed with the conductive gasket 45.
On the other hand, when the electromagnetic wave shielding glass is used as the curtain wall, when it is desired to make a part of the electromagnetic wave shielding glass openable / closable, as shown in FIGS. In addition, the conductive gaskets 45, 45, 45 having airtightness are provided between the joints of the plain material 23 and the shoji 22, the shoji 22 and the vertical frame 24, and the vertical frame 24 and the vertical 27. Is provided.

<Structure to install as a single window>
Moreover, an opening can be provided in the conductive metal panel, and a window can be constituted 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 of 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 wave shielding glass 5 by a conductive gasket 45 that fixes the electromagnetic wave shielding glass 5.

<Method of using parallel windows>
By the way, although the electromagnetic wave shielding glass used above needs to have a high performance with an electromagnetic wave shielding property of 40 db or more, the following shows a case where the electromagnetic wave shielding property has a low performance of about 25 db to 30 db. .
In this case, as shown in FIG. 41 and FIG. 42, the electromagnetic shielding performance is improved by installing two low performance electromagnetic shielding glasses 31 in parallel. Conductive gaskets 45, 45 are provided between the electromagnetic shielding surfaces 31 a, 31 a provided in the low-performance electromagnetic shielding glass 31, 31, the metal glass support frame 4, and the joint of the shoji frame 22. Thereby, the low-performance electromagnetic wave shield glasses 31 and 31, the glass support frame 4, and the shoji 22 are electrically connected.
In this case, it is recommended that the low-performance electromagnetic wave shielding glass 31 on the indoor side be a single-opening type or an open-and-close type such as an internal raising type for maintenance. As a method thereof, a conductive gasket 45 having an airtight performance is provided between the joints of the electromagnetic shielding surface 31 a provided in the low performance electromagnetic shielding glass 31 and the shoji frame 22. Thereby, the low performance electromagnetic wave shield glass 31 and the shoji 22 are electrically connected. The shoji 22 is also electrically connected to the lower frame 26 and the vertical frame 24 by the conductive gasket 45.
At present, high-performance electromagnetic shielding glass having electromagnetic shielding properties of 40 db or more is very expensive due to the complexity of the manufacturing process. Therefore, if low performance electromagnetic wave shielding glass is installed in parallel at a certain distance as in the present embodiment, an electromagnetic wave shielding property of 40 db or more can be secured at a low cost. Further, by installing the blind 32 inside, it is possible to reduce the load on a window space such as an office or a hospital. Furthermore, since the glass is installed twice, a sound insulation effect can be expected.

<Method to make outer wall structure fireproof>
When the outer wall structure is fireproof, the glass provided in the opening can be a 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 calcium oxalate plate, rock wool or the like, and this is placed on the back surface of the general glass 33 as an electromagnetic wave shield panel. The electromagnetic wave shield panel is electrically connected to the vertical 27 and the blanks 23 and 23 by the conductive gasket 45.
As the electromagnetic wave shielding panel, as shown in FIG. 45 and FIG. 46, a material obtained by attaching an electromagnetic wave shielding sheet 29 and an electromagnetic wave shielding tape 30 to the surface of the refractory material 34 may be used.

<About aluminum window frames>
As shown in FIG. 26, the aluminum glass support member (glass support frame 4) used in the present embodiment has two thin-walled portions parallel to the portion in which the electromagnetic wave shielding glass is fitted along the longitudinal direction of the mold material. The peeled portion 35 is formed by forming 35A and 35A, and a normal surface treatment such as an alumite film (may be baked on) is added to the surface of the glass support frame 4. However, since the alumite film is not generated at the time of the surface treatment of the hollow portion, the glass support frame 4 generates a high conductive surface 36 close to an aluminum substrate when the peeling portion 35 is peeled off during use. As shown in FIG. 27, the stripping portion 35 is preferably provided in a portion into which the conductive gasket is fitted, and also in a portion into which the electromagnetic wave shielding material is fitted as shown in FIG.

A conductive gasket 45 is provided between the glass support frames 4. Thereby, 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 high electrical conduction surface 36 close to the base of the aluminum frame. When the electromagnetic wave shielding glass is embedded in the glass support frame 4 shown in FIG. 27, the electromagnetic wave shielding glass 5 and the glass support frame 4 are provided on the floor side end of the electromagnetic wave shielding glass 5 as shown in FIG. The conductive sheet 44, the conductive gasket 45, and the high conductive surface 36 close to the base of the aluminum frame are electrically connected. Further, when the electromagnetic wave shielding glass 5 is embedded in the glass support frame 4 shown in FIG. 28, as shown in FIG. 31, the electromagnetic wave shielding material 2 and the glass support frame 4 are connected to the high conductive surface 36 close to the base of the aluminum frame. The electrical connection is made with the conductive gasket 45.

<About gasket type>
22 to 25 show a form of a conductive gasket and a shape of a field connection part used when connecting bent plate type metal panels. The conductive gasket 45 is integrally connected at the factory using a + -type and T-type forming material, and has a mesh shape as shown in FIG. As shown in FIG. 23, the end portion of the gasket that is connected in the field has a concave shape and a convex shape due to a conductive material such as conductive silicon, and after connection, as shown in FIG. The ends of the two gaskets fit together. FIG. 25 shows a case where the metal panels 1 and 1 are connected to the conductive state by the conductive gasket 45.

  Use aluminum panel and aluminum glass support member after anodizing (14μ or more) or aluminum composite coating (9 + 7μ), aluminum panel joint, aluminum panel and aluminum glass support As shown in Tables 1 to 4, when the joints between the members and the joints were connected, it was confirmed that an electromagnetic wave shielding performance of 40 db to 50 db could be secured in 200 MHZ to 3 GHz (see Tables 1 to 4). ).
