BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electromagnetic wave shield room constructed in a building, and relates to an electromagnetic wave shield room construction method suitable for application to a construction in which a metal-plated non-woven fabric is arranged on the entire interior surface.

[0002]

2. Description of the Related Art At present, with the rapid increase in OA equipment, harmful electromagnetic waves are generated from personal computers and the like, and there are many problems that cause malfunction of electric equipment. Therefore, an electromagnetic wave shielded room having a function of preventing the intrusion of electromagnetic waves generated outdoors or the leakage of electromagnetic waves generated indoors has been developed.

In order to block electromagnetic waves, the electromagnetic wave shielded room is basically provided with a shield material made of a highly conductive material without gaps over the entire interior surface including the walls, ceiling and floor of the room. It is constructed by grounding the shield material. Conventionally, as the shield material, a plate-shaped or foil-shaped material made of a metal having good conductivity such as copper has been used.

However, while these plate-shaped and foil-shaped metal materials are difficult to be cut and processed in an actual work site, in order to arrange and connect them on the indoor surface, soldering is not required. I shouldn't have. Moreover, various problems have arisen in that these operations require skill and require time for construction.

Therefore, recently, a non-woven fabric plated with a metal such as copper has been developed, and its use is being studied and researched as a substitute for a plate material or a foil material which has been conventionally used. This non-woven fabric is lightweight and can be easily processed such as cutting, and connection between non-woven fabrics can be completed by applying adhesive to one non-woven fabric and stacking the other non-woven fabric on it. Since it is easy to handle, it has the advantages that no skill is required for the work and that the construction time is short. Research and development of an electromagnetic wave shielded room constructed by using this non-woven fabric is currently underway.

FIG. 3 is an enlarged vertical sectional view showing a wall portion of a conventional electromagnetic wave shield room. Conventionally, the non-woven fabric 6 is not directly arranged on the light iron substrate 2, but before the non-woven fabric 6 is arranged, the plaster board 4 is first provided, and this is used as a substrate to form the non-woven fabric 6 on the surface of the plaster board 4. Was laid, and the plaster board 8 was provided on the non-woven fabric 6, and finishing such as cloth pasting and painting was performed using this surface.

Therefore, at the construction site, the plasterboard 4 is arranged on the light iron substrate 2 and the non-woven fabric 6 as the shield material is fixed with the plasterboard 4 as the substrate. However, since it is necessary to carry out the construction twice, which is time-consuming, there is a problem that it takes a very long time.

The present invention has been made in view of the above circumstances, and is a method for constructing an electromagnetic shield room that does not require much labor for constructing a shield material and can save labor in construction or shorten the construction period. To provide.

SUMMARY OF THE INVENTION According to the present invention, a dry panel in which a metal-plated non-woven fabric is struck on the surface is integrally molded in advance, and then the dry panels are arranged side by side with the non-woven fabric surface facing the indoor side. Then, the non-woven fabric surface is overlapped over the side edges of the dry panels adjacent to each other, a joint tape made of the same material as the non-woven fabric is attached, and further, a coating material is applied on the non-woven fabric and the joint tape surface. It is characterized by having done.

[0010]

The operation of the present invention will be described. A dry panel in which a metal-plated non-woven fabric is struck on the surface is integrally molded beforehand. Therefore, when the dry panel is molded, the non-woven fabric is arranged and driven to impregnate the inside of the non-woven fabric with gypsum or the like, and when this is solidified, the non-woven fabric is securely fixed to the dry panel. Next, the dry panels are arranged side by side with the non-woven fabric surface facing the indoor side. Therefore, most of the construction of the dry panel and the construction of the non-woven fabric as the shield material can be performed at the same time. As the construction of the remaining shield material, the construction of the shield material is completed by laminating the non-woven fabric surface over the non-woven fabric surface between the edges of the adjacent dry type panels and adhering the joint tape made of the same material as the non-woven fabric. Therefore, compared to the case where the plasterboard is first placed on the construction site as in the past and then the nonwoven fabric is fixed to the indoor surface from the beginning, the construction area of the shield material on the site is reduced and it does not take time and effort. Therefore, the time required to construct a shielded room is shortened.

Further, the finishing can be completed by applying a paint on the surface of the non-woven fabric and the joint tape which can be handled like cold chill, and the paint is a non-woven fabric and a joint formed of the same material as the non-woven fabric. The inside of the tape is impregnated, and the nonwoven fabric and the joint tape are integrated as reinforcements to form a strong paint film.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT A preferred embodiment of the present invention will be described in detail below with reference to the accompanying drawings. An electromagnetic wave is a wave that propagates in space as a set of an electric field and a magnetic field. In order to block the propagation of this electromagnetic wave, a conductor such as metal is placed in the direction of the source of the electromagnetic wave,
There is a way to ground it. This is because the electromagnetic wave propagates and collides with the grounded conductor to be absorbed. However, since electromagnetic waves are waves and spread concentrically from the source, if there is an obstacle in the direction of its propagation, it may be reflected and transmitted by the obstacle, so it is not always directly transmitted from the source. Not exclusively. Moreover, since some sources come from other sources,
It is necessary to arrange conductors in all directions. Therefore, in order to construct a shielded room in which electromagnetic waves are blocked, it is necessary to dispose a conductive material such as metal so that there is no gap on the entire interior surface and ground it.

1 and 2 are a perspective view and a vertical sectional view showing an embodiment of an electromagnetic wave shield room according to the present invention. A dry panel 12 having a metal-plated non-woven fabric 14 stamped on its surface is integrally molded in advance, and then the dry panel 12 is formed.
The non-woven fabric 14 surface is lined up toward the room 18 side, and is fixed to the ceiling surface and the floor surface using the runner 30 so as not to cause a deviation due to a screw or the like to construct a wall. Then, the non-woven fabric 1 is provided between the side edges of the dry panels 12 adjacent to each other.
A joint tape 16 made of the same material as the non-woven fabric 14 is stuck on the four surfaces, and a paint is applied to the surfaces of the non-woven fabric 14 and the joint tape 16. Further, the concrete 20 surface is exposed on the ceiling or floor of the room 18, the plaster board 22 is arranged on the ceiling surface, the non-woven fabric 14 is fixed on the plaster board 22 surface, and then the ziptone (trade name) ) 24 to complete the finish, while the floor surface has a floor coat (trade name) 2
6 is provided, the non-woven fabric 14 is laid and fixed thereon, and a vinyl tile 28 is laid on the non-woven fabric 14 to complete the finishing. Each of the non-woven fabrics 14 fixed to the ceiling, floor and wall is the same as the neighboring non-woven fabrics 14 and the joint tape 1.
It is possible to block electromagnetic waves by connecting them without any gap by means of 6 or the like and grounding them.

The non-woven fabric 14 is a fabric made by treating synthetic fibers mechanically, chemically and thermally and joining them by the adhesive force of an adhesive or the fusion force of itself, and the surface thereof is made of copper or the like. It is plated with a metal with good conductivity and plays the role of a shield material. As the non-woven fabric 14, there is Flextron (trade name), which is used in this embodiment to construct an electromagnetic shield room. Since the material is porous like gauze and rich in extensibility, it can be followed even in the event of an earthquake or other vibrations, so that cracks etc. can be prevented from occurring after construction.

The dry type panel 12 is a gypsum board or the like formed by driving plaster or mortar into a mold.
The dry type panel 12 is formed by driving plaster or the like into the non-woven fabric 14 when it is not yet dried, and at the same time, integrally molded. Further, in this embodiment, since it is constructed as a wall, it has a size suitable for the room and is molded in a plate shape, but depending on the shape of the room to be constructed, it may be bent to have a roundness. You may.

The joint tape 16 is made of the same material as the non-woven fabric 14 and is formed into a strip shape. Like the non-woven fabric 14, the joint tape 16 is plated with a metal having good conductivity, and the material is porous like gauze. is there. In addition, it is extremely lightweight and can be easily cut and processed compared with the metal plate used as a conventional shield material, and it has a finger grip compared to a metal foil that causes wrinkles or breaks. Easy to handle without damaging In addition, the non-woven fabrics 14 can be adhered to each other by using an adhesive such as emulsion type, synthetic rubber or starch paste by utilizing the porous property like this gauze, and excess glue is removed through the holes at this time. Since it is possible to have good conductivity when it is stacked on the surface of the non-woven fabric 14, it is possible to carry out the work as if handling paper without the need for soldering work.

As is clear from the above, the dry type panel 12 having the surface plated with the metal-plated nonwoven fabric 14 is integrally molded in advance. Therefore, when the dry panel 12 is molded, the non-woven fabric 14 that is a porous material such as gauze can be formed by placing the non-woven fabric 14 on the surface and driving it before the plaster or the like that is the material is solidified. When the inside is impregnated and the gypsum or the like is solidified, the non-woven fabric 14 is securely fixed to the dry panel 12. Therefore, as compared with the case where the nonwoven fabric 14 is fixed to the already-molded dry type panel 12 afterwards, the adhesive force does not decrease, and therefore, the deviation does not occur later.

Next, the dry panel 12 is attached to the non-woven fabric 1 thereof.
The four surfaces are arranged side by side toward the room 18 side. Nonwoven fabrics 14 are fixed in advance on the surfaces of the dry panels 12 juxtaposed with each other, and a gap is formed between adjacent dry panels 12 to which the nonwoven fabrics 14 are not connected. Therefore, the joint tape 16 made of the same material as the non-woven fabric 14 is juxtaposed on the non-woven fabric 14 surface of the dry type panel 12 so as to be juxtaposed over the side edges of the adjacent dry type panels 12 in which the gaps are formed. The dry panels 12 can be connected to each other. The nonwoven fabric 14 is grounded and has a function of blocking electromagnetic waves. Further, by arranging the dry panels 12 in which the non-woven fabric 14 is integrally molded in advance, the dry panel 12 and the non-woven fabric 14 as the shield material can be installed almost at the same time. As the construction of the remaining shield material, the joint tape 16 made of the same material as the non-woven fabric 14 is attached to the surface of the non-woven fabric 14 so as to overlap between the side edges of the adjacent dry type panels 12, and the construction of the shield material is completed. .
Therefore, as compared with the conventional case where the nonwoven fabric 14 is fixed from the beginning to the plaster board surface arranged on the indoor surface where no shield material is applied at the construction site, the construction area of the shield material is reduced. However, since it does not take time and effort, the time required for constructing the shield room is shortened.

Further, the finishing can be completed by applying the coating material on the surface by using the non-woven fabric 14 and the joint tape 16 like cold chills. Further, this paint is impregnated into the nonwoven fabric 14 and the joint tape 16 formed of the same material as the nonwoven fabric 14 and is integrated by reinforcing the nonwoven fabric 14 and the joint tape 16 to form a strong paint film 32. Thereby, the non-woven fabric 14
And the joint tape 16 is sufficiently protected. Further, after the shield room is constructed, the adhesive ability is lowered at the connecting portion between the non-woven fabric 14 and the joint tape 16,
And paint film 3 integrated with joint tape 16
When an abnormality such as a crack occurs in 2, it can be found directly from the room 18, and the non-woven fabric 14 can be fixed again or repaired using the joint tape 16 or the like. it can. Therefore, it is possible to easily recognize the deterioration of the shield performance visually and immediately repair it, so that it is possible to reliably maintain the shield performance.

[0020]

According to the present invention, a dry panel having a surface coated with a metal-plated nonwoven fabric is integrally molded in advance.
Therefore, since the non-woven fabric is securely fixed to the dry type panel, the adhesive strength does not decrease compared to the case where the non-woven fabric is fixed to the already solidified dry type panel by retrofitting. Can be maintained for a long time.

Next, the dry panels are arranged side by side with their non-woven fabric surfaces facing the interior. Therefore, the construction of the dry panel and the construction of the non-woven fabric as the shield material can be carried out almost at the same time. As the construction of the remaining shield material, the construction of the shield material is completed by laminating the non-woven fabric surface over the non-woven fabric surface between the edges of the adjacent dry type panels and adhering the joint tape made of the same material as the non-woven fabric. Therefore, compared to the case where the non-woven fabric is fixed to the indoor surface from the beginning at the construction site as in the past, the construction area of the shield material is reduced, and since it does not take time and labor, the time required for the shield material construction is shortened. It As a result, it is possible to save labor in the construction of the shield room and shorten the construction period.

Further, a paint is applied on the surface of the non-woven fabric and the joint tape, and the paint is impregnated inside the non-woven fabric and the joint tape formed of the same material as the non-woven fabric and the non-woven fabric and the joint tape to form a strong paint film. Since it is formed, the nonwoven fabric and the joint tape are sufficiently protected. Furthermore, after the construction of the shield room, if the adhesive capacity at the connection between the non-woven fabric and the joint tape deteriorates and cracks occur in the paint film that is integrated with the non-woven fabric, this should be found directly from the room. Then, the non-woven fabric can be re-fixed or repaired using joint tape or the like again. Therefore, it becomes possible to easily recognize the deterioration of the shield performance visually and immediately repair it, so that it is possible to reliably maintain the shield performance.
