Description

  The present invention relates to an installation method of an electromagnetic wave shield room and an improvement of a shielded plywood panel used therefor.

As an installation method of an electromagnetic wave shielding room in which an electromagnetic wave shielding room is formed by stretching metal foil for electromagnetic wave shielding made of copper or the like in a building, a method using a so-called augmentation method is known.
When installing an electromagnetic shielding room by the building augmentation method, first, install a number of light-weight steel (light gauge studs) vertically between the floor slab and ceiling slab of the building at horizontal intervals. Then, with the rectangular plywood panel in contact with the lightweight steel from the room side, a tapping screw etc. is passed through from the surface side of the plywood panel and screwed into the pilot hole of the lightweight steel to make the plywood panel long Repeat the work of fixing to steel, arrange a number of plywood panels without gaps in the horizontal direction, and after installing all the plywood panels to be attached, place the metal for electromagnetic wave shielding on the plane formed by a series of plywood panels It is common to form each surface of the outer peripheral part of an electromagnetic shielding room by sticking foil using adhesives, such as a woodworking bond.
Moreover, the connection between the metal foils for electromagnetic shielding adhered to each plane forming the outer periphery of the electromagnetic shielding room, and the metal foil for electromagnetic shielding adhered to each plane forming the outer periphery of the electromagnetic shielding room and Interconnection with the electromagnetic shielding metal foil affixed to the surface of the plywood panel on the ceiling side, and the electromagnetic foil shielding metal foil affixed to each plane forming the outer periphery of the electromagnetic shielding room and the floor side plywood For interconnection with the electromagnetic shielding metal foil attached to the surface of the panel, the tape-like electromagnetic shielding metal foil is bent along the corners formed at the abutting portion of each plane, and the tape This is generally realized by soldering both sides of the metal foil for electromagnetic wave shielding in the width direction to each of the metal foil for electromagnetic wave shielding on each adjacent plane.
However, in the known method of installing an electromagnetic shielding room to which the building augmentation method is applied, it is necessary to stick a large-area electromagnetic shielding metal foil on a plane formed by a series of plywood panels. It is difficult to handle the metal foil, and high skill is required for the workers.
In addition, a large amount of adhesive must be uniformly applied to a plane formed by a series of plywood panels, and a curing time is required to wait for the adhesive to harden, resulting in an inconvenience that the work takes a long time. was there.
Furthermore, buildings with electromagnetic shielding rooms usually have few doors and windows, especially in the process of attaching electromagnetic shielding metal foil to a plane formed by a series of plywood panels. Since the property becomes high and ventilation becomes insufficient, there is also a disadvantage that the adhesive that can be used in the sticking operation is limited to a non-volatile adhesive such as an emulsion-type aqueous adhesive.

As another method for forming an electromagnetic wave shield room by stretching an electromagnetic wave shield metal foil in a building, a method using a shield panel for a magnetic / radio wave shield room as disclosed in Patent Document 1 is used. It has been known.
This is designed to define an electromagnetic shield room using a dedicated connecting member independent of the shield panel mounted with the shield plate, but to secure the independence by omitting the support column that supports the shield panel When combining shield panels along the same plane, an independent connecting member dedicated to plane connection is required, and the shield panel is installed at the corner butt. Requires an independent connecting member dedicated to corner connection, which has a substantially L-shape.
In addition, if the corner part of the room has a crossing angle other than a right angle, a connecting member having a dedicated angle corresponding to the angle is produced again, or the dimension inscribed in the specific shape of the room is maximized. Since there is no other way to install a rectangular electromagnetic shield room that is the limit, it is not suitable for installing an electromagnetic shield room that makes the most of the room shape and site area.
In Patent Document 1, no particular consideration is given to electrical connection between a shield plate attached to a shield panel installed upright and a ceiling-side shield or a floor-side shield.

  As another installation method, an electromagnetic wave shield room that can be moved up and down is constructed as Patent Document 2, but this does not allow the entire room to function as an electromagnetic wave shield room. It is intended to construct a simple electromagnetic shielding room part-time in a certain area of the room, and is not suitable for the installation of an electromagnetic shielding room that makes the most of the site area of the room.

Patent No. 3338826 (paragraphs 0029, 0038, 0007, 0036) Japanese Patent No. 4776015

  Therefore, the object of the present invention is to improve the disadvantages of the prior art, and can perform the installation work in a short time without requiring a high degree of skill, and without requiring a special connecting member, the shape of the room. It is another object of the present invention to provide an electromagnetic wave shield room installation method and a shielded plywood panel capable of installing an electromagnetic wave shield room by making the most of the site area.

The electromagnetic shielding room installation method in the present invention achieves the above-mentioned object,
When the electromagnetic shielding room is formed, a rectangular shape with an electromagnetic shielding metal foil attached to the surface with an overhanging portion for electrical connection with the electromagnetic shielding metal foil of a plywood panel installed at an adjacent position. On the back surface of the plywood panel, a plurality of locking members having an overall length comparable to the lateral width and a substantially L-shaped cross section are provided at regular intervals along the longitudinal direction of the plywood panel. A plurality of shielded plywood panels, which are orthogonal to each other and fixed in an aligned manner so that a corner portion of a substantially L-shaped cross section is concave toward one of the longitudinal directions of the plywood panel, Prior to the shield room installation work, pre-manufactured in the factory,
When installing the electromagnetic shielding room, first, install a plurality of lightweight steel bars vertically between the floor slab and ceiling slab of the building at intervals in the horizontal direction.
A plurality of long steels having a substantially L-shaped cross section on each of the plurality of light-weight shaped steels on a room-side surface, with a constant interval the same as the interval between the locking members in the vertical direction. After fixing it horizontally with the corner part of the cross section being concave upward,
Each of the plurality of shielded plywood panels is engaged with a concave portion of each corner portion of each of the plurality of long steel pieces from above, by engaging a concave portion of each corner portion of the plurality of long steels from above. Is fixed to each of the plurality of long steels,
By soldering the projecting portion of the electromagnetic shielding metal foil in each shielded plywood panel to the electromagnetic shielding metal foil attached to the surface of the adjacent plywood panel,
An electromagnetic wave shielding room defined by a metal foil for electromagnetic wave shielding is formed.

The electromagnetic shield room installation method according to the present invention is such that a plurality of light-weight shaped steels are installed vertically between a floor slab and a ceiling slab of a building at intervals in the horizontal direction, A plurality of long steels having a substantially L-shaped cross section are fixed horizontally on the surface of the steel plate so that the corner portions of the substantially L-shaped cross section are concave upward in the vertical direction at regular intervals. After that, a plurality of pieces fixed to the back surface of the rectangular plywood panel so as to be orthogonal to the longitudinal direction of the plywood panel at intervals equivalent to the vertical intervals in the long steel along the longitudinal direction thereof And engaging the concave portions of the respective corner portions of the engaging members on the back surface of the shield plywood panel with the concave portions of the respective corner portions of the plurality of long steel plates from above. By combining the locking member and the long steel Each of the plurality of plywood panels is fixed to a lightweight steel, and the lightweight steel itself can be installed at any position as long as it is between the floor slab and ceiling slab of the building. Install the electromagnetic shielding room by making the best use of the site area of the room by matching the shape of the outer periphery of the shielding room to an arbitrary shape, for example, a shape that follows the unique shape of the room or a desired rectangular shape. can do.
In addition, the electromagnetic foil shielding metal foil of the shielded plywood panel has an overhanging portion for electrically connecting to the electromagnetic shielding metal foil attached to the surface of the adjacent plywood panel. The shield metal foil can be freely bent and electrically connected to the electromagnetic shield metal foil adhered to the surface of the adjacent plywood panel by soldering, so the outer periphery of the electromagnetic shield room can be formed. Even if it is made to follow the unique shape of the room, that is, when adjacent plywood panels are abutted at a crossing angle other than a right angle, a metal foil for electromagnetic wave shielding is used without using an independent special connecting member. Can be easily stretched around the building.
In addition, the electromagnetic shielding metal foil is pre-adhered to the surface of the plywood panel in the factory prior to the installation work, so a large area is added to the series of plywood panels combined during the installation work of the electromagnetic shielding room. There is no need to attach a metal foil for electromagnetic shielding. Therefore, no special skill is required for the person in charge of the installation work on site, and no curing time is required to wait for the adhesive to harden, so the installation work can be completed in a short time. The labor of the person in charge is reduced.
Furthermore, even when a metal foil for electromagnetic wave shielding is stuck on a plywood panel using a volatile adhesive, the sticking work can be performed in advance in a factory where ventilation work is free. Since there is no need for affixing work in a poor building, there is no risk of adverse effects such as volatile solvents on the workers.

  If the metal foil for electromagnetic shielding is provided with a lateral overhanging portion for electrical connection with the metal foil for electromagnetic shielding attached to the surface of the plywood panel adjacent to the side, this side The overhanging portion is soldered to an electromagnetic shielding metal foil adhered to the surface of the plywood panel adjacent to the side.

  Even if the metal foil for electromagnetic wave shielding has only a laterally protruding portion, the tape-like metal foil for electromagnetic wave shielding is formed along the corner formed at the abutting portion between the shielded plywood panel and the ceiling side plywood panel. Installed by bending and soldering both sides of the tape-like metal foil for electromagnetic shielding to the electromagnetic shielding metal foil of the shielded plywood panel and the metal foil for electromagnetic shielding attached to the surface of the ceiling-side plywood panel In addition, the tape-shaped metal foil for electromagnetic shielding is bent and installed along the corner formed at the abutting part between the shielded plywood panel and the floor-side plywood panel, and both sides of the tape-shaped electromagnetic shielding metal foil are shielded. Solder to each of the electromagnetic foil shielding metal foil of the plywood panel and the electromagnetic shielding metal foil attached to the surface of the floor side plywood panel. It is possible to install an electromagnetic wave shielding room by case.

  If the metal foil for electromagnetic wave shielding is provided with an upper overhanging part for electrical connection with the metal foil for electromagnetic wave shielding adhered to the surface of the plywood panel on the ceiling side, the upper overhanging part is further provided. Is solder-bonded to the electromagnetic shielding metal foil adhered to the surface of the plywood panel on the ceiling side.

When such a configuration is applied, it is not necessary to bend and install the tape-shaped electromagnetic shielding metal foil along the corner formed at the butt portion of the shielded plywood panel and the ceiling-side plywood panel. The soldering operation is further simplified.
The reason for this is that the upper projecting part is integrated with the electromagnetic shielding metal foil of the shielded plywood panel, and the tip of the upper projecting part, that is, only one side, is attached to the surface of the ceiling side plywood panel. This is because solder bonding to the foil is sufficient.

  Further, when the electromagnetic shielding metal foil is provided with a downward projecting portion for electrical connection with the electromagnetic shielding metal foil attached to the surface of the floor-side plywood panel, this lower part is further provided. The overhanging portion is soldered to an electromagnetic shielding metal foil adhered to the surface of the plywood panel on the floor side.

When such a configuration is applied, it is not necessary to bend and install the tape-shaped electromagnetic shielding metal foil along the corner formed at the butt portion of the shielded plywood panel and the floor side plywood panel. The soldering operation is further simplified.
The reason is that the lower projecting part is integrated with the electromagnetic shielding metal foil of the shielded plywood panel, and the tip of the lower projecting part, that is, only one side, is adhered to the surface of the floor side plywood panel. This is because solder bonding to the foil is sufficient.

The shielded plywood panel in the present invention is a shielded plywood panel used for installation of an electromagnetic shielding room, and in order to achieve the same object as described above,
A rectangular plywood panel;
When the electromagnetic shielding room is formed, an overhanging portion for electrically connecting to the metal foil for electromagnetic shielding that is attached to the surface of the plywood panel that is installed at an adjacent position is provided on the surface of the plywood panel. A metal foil for electromagnetic wave shielding,

Moreover, the electromagnetic foil shielding metal foil of the shielded plywood panel is provided with an overhanging portion for electrically connecting to the electromagnetic shielding metal foil attached to the surface of the adjacent plywood panel. The shield metal foil can be freely bent and electrically connected to the electromagnetic shield metal foil adhered to the surface of the adjacent plywood panel by soldering, so the outer periphery of the electromagnetic shield room can be formed. Even if it is made to follow the unique shape of the room, that is, when adjacent plywood panels are abutted at a crossing angle other than a right angle, a metal foil for electromagnetic wave shielding is used without using an independent special connecting member. Can be easily stretched around the building.
In addition, the electromagnetic shielding metal foil is pre-adhered to the surface of the plywood panel in the factory prior to the installation work, so a large area is added to the series of plywood panels combined during the installation work of the electromagnetic shielding room. There is no need to attach a metal foil for electromagnetic wave shielding, and no special skill is required for the person in charge of the installation work on site. And since the curing time which waits for hardening of an adhesive agent is also unnecessary, installation work can be completed in a short time and the labor of a worker in charge is reduced.
Furthermore, even when a metal foil for electromagnetic wave shielding is stuck on a plywood panel using a volatile adhesive, the sticking work can be performed in advance in a factory where ventilation work is free. Since there is no need for affixing work in a poor building, there is no risk of adverse effects such as volatile solvents on the workers.

  It is desirable that the metal foil for electromagnetic wave shielding includes a side projecting portion for electrically connecting to the metal foil for electromagnetic wave shielding attached to the surface of the plywood panel adjacent to the side when installing the electromagnetic wave shielding room. .

  Even if the metal foil for electromagnetic wave shielding has only a laterally protruding portion, the tape-like metal foil for electromagnetic wave shielding is formed along the corner formed at the abutting portion between the shielded plywood panel and the ceiling side plywood panel. Installed by bending and soldering both sides of the tape-like metal foil for electromagnetic shielding to the electromagnetic shielding metal foil of the shielded plywood panel and the metal foil for electromagnetic shielding attached to the surface of the ceiling-side plywood panel In addition, the tape-shaped metal foil for electromagnetic shielding is bent and installed along the corner formed at the abutting part between the shielded plywood panel and the floor-side plywood panel, and both sides of the tape-shaped electromagnetic shielding metal foil are shielded.

The reason for this is that the upper projecting part is integrated with the electromagnetic shielding metal foil of the shielded plywood panel, and the tip of the upper projecting part, that is, only one side, is attached to the surface of the ceiling side plywood panel. This is because solder bonding to the foil is sufficient.

  Furthermore, the metal foil for electromagnetic wave shielding may be configured to have a downward projecting portion for electrically connecting to the metal foil for electromagnetic wave shielding attached to the surface of the plywood panel on the floor side when installing the electromagnetic wave shielding room. Good.

When such a configuration is applied, it is not necessary to bend and install the tape-shaped electromagnetic shielding metal foil along the corner formed at the butt portion between the shielded plywood panel and the floor side plywood panel. The joining operation is further simplified.
The reason is that the lower projecting part is integrated with the electromagnetic shielding metal foil of the shielded plywood panel, and the tip of the lower projecting part, that is, only one side, is adhered to the surface of the floor side plywood panel. This is because solder bonding to the foil is sufficient.

  Moreover, it is desirable that the plurality of locking members fixed to the back surface of the plywood panel are made of a free-cutting material that can be easily cut, such as wood.

  By using an easy-to-cut free-cutting material for the locking member that adheres to the back of the plywood panel, it is possible to easily cut and cut a shielded plywood panel with a metal foil for electromagnetic wave shielding and a locking member with a chain saw.

The plurality of locking members and the long steel are used, and the concave portion of each corner portion of the locking member on the back surface of the shielded plywood panel is raised above the concave portion of each corner portion of the plurality of long steel plates. By engaging from the locking part Each of the plurality of plywood panels is fixed to the lightweight shape steel through the steel and the long shape steel, and the light weight shaped steel itself is optional as long as it is between the floor slab and the ceiling slab of the building. Since the shape of the outer periphery of the electromagnetic shielding room can be adjusted to an arbitrary shape, for example, a shape that follows the unique shape of the room or a desired rectangular shape, the maximum area of the room can be utilized. Thus, an electromagnetic shielding room can be installed.
In addition, the electromagnetic foil shielding metal foil of the shielded plywood panel has an overhanging portion for electrically connecting to the electromagnetic shielding metal foil attached to the surface of the adjacent plywood panel. The shield metal foil can be freely bent and electrically connected to the electromagnetic shield metal foil adhered to the surface of the adjacent plywood panel by soldering, so the outer periphery of the electromagnetic shield room can be formed. Even if it is made to follow the unique shape of the room, that is, when adjacent plywood panels are abutted at a crossing angle other than a right angle, a metal foil for electromagnetic wave shielding is used without using an independent special connecting member. Can be easily stretched around the building.
In addition, the electromagnetic shielding metal foil is pre-adhered to the surface of the plywood panel in the factory prior to the installation work, so a large area is added to the series of plywood panels combined during the installation work of the electromagnetic shielding room. There is no need to attach a metal foil for electromagnetic wave shielding, and no special skill is required for a worker in charge of installation work on site. And since the curing time which waits for hardening of an adhesive agent is also unnecessary, installation work can be completed in a short time and the labor of a worker in charge is reduced.
Furthermore, even when a metal foil for electromagnetic wave shielding is stuck on a plywood panel using a volatile adhesive, the sticking work can be performed in advance in a factory where ventilation work is free. Since there is no need for affixing work in a poor building, there is no risk of adverse effects such as volatile solvents on the person in charge.

  In particular, in the case where the electromagnetic shielding metal foil has only a laterally protruding portion, the tape-shaped electromagnetic shielding metal is formed along the corner formed at the abutting portion between the shielded plywood panel and the ceiling-side plywood panel. Fold the foil and place both sides of the tape-shaped electromagnetic shielding metal foil on the electromagnetic shielding metal foil of the shielded plywood panel and the electromagnetic shielding metal foil attached to the surface of the ceiling side plywood panel. At the same time, both sides of the tape-shaped electromagnetic shielding metal foil are installed by bending the tape-shaped electromagnetic shielding metal foil along the corner formed at the abutting portion of the shielded plywood panel and the floor-side plywood panel. For each of the electromagnetic foil shielding metal foil of the shielded plywood panel and the electromagnetic shielding metal foil adhered to the surface of the floor side plywood panel So as to install the electromagnetic wave shielding room by Sunda bonding.

  In addition, when the electromagnetic shielding metal foil includes an upward projecting portion for electrically connecting to the electromagnetic shielding metal foil attached to the surface of the plywood panel on the ceiling side when installing the electromagnetic shielding room, This eliminates the need to fold and install a tape-shaped metal foil for electromagnetic shielding along the corner formed at the abutting part between the shielded plywood panel and the ceiling-side plywood panel, further simplifying the soldering operation.

The electromagnetic shielding metal foil 15 including the side projecting portion 15a, the upper projecting portion 15b, and the lower projecting portion 15c is formed of a copper foil having a thickness of about 0.07 mm, and is easily bent.

The locking member 16 is made of a free-cutting material that can be easily cut. In this embodiment, as shown in FIG. 4 (b), the locking member 16 has a rectangular cross section with a different total width and a total length comparable to the lateral width of the plywood panel 14. The two woods 16a and 16b are combined.
The locking member 16 made of wood 16a, 16b has a concave portion, that is, a corner portion 16c defined by a stepped portion of the wood 16a, 16b, in one of the longitudinal directions of the plywood panel 14, that is, FIG. In (d), the direction is aligned so as to be concave downward, and it is fixed to the back surface of the plywood panel 14 with a wood screw 17.
In some cases, the back surface of the plywood panel 14 and the wood 16a and the wood 16a and the wood 16b are bonded with a woodwork bond or the like.
Since the entire length of the locking member 16 is slightly shorter than the lateral width of the plywood panel 14 as shown in FIGS. 3 (b) and 5 (a), the laterally projecting portion of the metal foil 15 for electromagnetic wave shielding 15a can be tightly wound from the right edge of the plywood panel 14 to the back surface, and is useful for preventing damage to the electromagnetic shielding metal foil 15 when the shield plywood panel 27 is transported from the factory to the assembly site. In addition, although the redundant extension part 15d exists also in the other side of the metal foil 15 for electromagnetic wave shielding which provided the side protrusion part 15a, this extension part 15d is shown in FIG. 5 (a) and FIG. ), It is attached to the edge and back surface of the plywood panel 14.
The distance X1 from the lower edge of the plywood panel 14 to the lowermost locking member 16 in the longitudinal direction of the plywood panel 14 and the uppermost locking member 16 in the longitudinal direction of the plywood panel 14 The value of the separation distance X2 to the upper edge depends on the installation status of the long steel 26 used for attaching the shield plywood panel 27 and between the plywood panel 23 installed on the ceiling side and the plywood panel 19 installed on the floor side. The distance is adjusted according to the vertical distance required for the plywood panel 14.

  Next, assuming that the production of the number of shield plywood panels 27 required for the installation of the electromagnetic wave shield room has already been completed, an installation method of the electromagnetic wave shield room using the shield plywood panel 27 of this embodiment is shown in FIG. Will be described in detail.

  As already described, the hatched portion indicated by reference numeral 9 in FIG. 2 is an existing wall constituting a part of the building.

  In this embodiment, it is assumed that an electromagnetic wave shield room is installed along the inner wall of the MRI examination room 1 shown in FIG. 1, but the method of attaching the shield plywood panel 27 along the existing wall 9 is on any surface. Therefore, the existing wall 9 in FIG. 2 can be considered as any one of the existing walls 9 shown in FIG.

On the floor slab 18 in the MRI examination room 1, an electromagnetic shielding metal foil 20 made of copper or the like is attached to the upper surface of a plywood panel 19 having a waterproof sheet and a shield mesh on the surface, and MRI examination is performed. On the ceiling side of the chamber 1, an electromagnetic shielding metal foil 24 made of copper or the like is attached to a plywood panel 23 attached to a suspension bolt 21 whose base is fixed to a ceiling slab (not shown) via a light ceiling base 22. Install.
Since the installation work of the plywood panel 19 and the electromagnetic foil shielding metal foil 20 on the floor side and the installation work of the plywood panel 23 and the electromagnetic shielding metal foil 24 on the ceiling side are already known, detailed description thereof is omitted here.

When attaching the shielded plywood panel 27 along the existing wall 9, first, a plurality of light-weight shaped steel (light gauge studs) 25 are provided with a certain clearance between the existing wall 9 and the horizontal direction, i.e., FIG. 2 is installed vertically between the floor slab 18 and the ceiling slab of the building with an interval in the direction perpendicular to the paper surface, and a substantially L-shaped section 26a and a mounting portion 26b as shown in FIG. As shown in FIG. 3 (a), a plurality of long steel pieces 26 having a plurality of long steel pieces 26 are provided on the surface on the indoor side of each of the light weight steel pieces 25, as shown in FIG. In the vertical direction, X is fixed horizontally by a screw or spot welding or other known means so that the corner portion 26c of the substantially L-shaped cross section is concave upward.
Since it is necessary to prevent the vertical displacement in the vertical direction when installing the long steel 26, the installation height of the long steel 26 at each stage is a reference as shown in FIG. In general, it is indicated by an absolute value based on the surface height of the floor slab 18 or the like. The constant interval X is the same as the interval between the stop members 16.
In addition, the value of the separation distance X1 from the lower edge of the plywood panel 14 described in relation to the configuration of the plywood panel 14 to the lowermost locking member 16 is the longest length of the lowermost stage used for attaching the shield plywood panel 27. It is assumed that it has been optimized by processing in the factory according to the mounting height X3 of the shape steel 26.

  Next, in the shield plywood panel 27, the electromagnetic wave shielding metal foil 15 wound from the right side edge of the plywood panel 14 to the back surface of the electromagnetic shield metal foil 15 and the electromagnetic shield metal foil 15 wound from the upper edge to the back surface of the plywood panel 14. The upper projecting portion 15b and the lower projecting portion 15c of the electromagnetic shielding metal foil 15 wound from the lower edge to the back surface of the plywood panel 14 are appropriately bent from the storage position during conveyance as shown in FIG. In this state, the shield plywood panel 27 is lifted while being pulled out to the near side of the plywood panel 14, and the recesses 16 c at the corner portions of the locking members 16 fixed to the back surface of the plywood panel 14 are arranged in a plurality of long lengths. It is necessary for the construction of one wall surface by engaging with the concave portion 26c of each corner portion of the shape steel 26 from above. A plurality of shielded plywood panels 27 are arranged in close contact with each other in the horizontal direction along the longitudinal direction of the long steel 26, and a plurality of shielded plywoods are used by utilizing the concave and convex fitting between the locking member 16 and the long steel 26. Each of the panels 27 is fixed to the lightweight section steel 26 as shown in FIG. 2 and FIG.

  Then, the side projecting portion 15a of the electromagnetic shielding metal foil 15 in each shield plywood panel 27 is attached to the side of this shield plywood panel 27, that is, the surface of the plywood panel 14 located rearward in FIG. 5B, a polymerized portion 35 as shown in FIG. 5B is formed between the metal foil 15 for electromagnetic wave shielding and the leftmost portion of the surface of the metal foil 15 for electromagnetic wave shielding. By soldering the leading edge of 15a to the surface of the adjacent electromagnetic shielding metal foil 15, the electromagnetic shielding metal foils 15 and 15 of the adjacent shield plywood panels 27 and 27 are electrically connected. To do.

  Further, as shown in FIG. 6 (a), the electromagnetic wave attached to the surface (lower surface) of the plywood panel 23 on the ceiling side as shown in FIG. 6 (a). After bending toward the indoor side at a position in contact with the shielding metal foil 24 to form a superposed portion 28 of the electromagnetic shielding metal foil 24 and the upper overhanging portion 15b, the most advanced portion of the upper overhanging portion 15b is ceilingd The adjacent electromagnetic shielding metal foils 15 and 24 are electrically connected by soldering to the outer periphery of the electromagnetic shielding metal foil 24 on the side.

  Further, as shown in FIG. 6B, the electromagnetic wave shield adhered to the surface of the plywood panel 19 on the floor side with the downward projecting portion 15c of the metal foil 15 for electromagnetic wave shielding in each shielded plywood panel 27. The metal foil 20 is bent toward the indoor side at a position where it abuts the metal foil 20 to form a superposed portion 29 of the electromagnetic shielding metal foil 20 and the lower overhanging portion 15c, and then the most advanced portion of the lower overhanging portion 15c is placed on the floor side. These adjacent electromagnetic foil shielding metal foils 15 and 20 are electrically connected by soldering to the outer peripheral portion of the electromagnetic shielding metal foil 20.

  As described above, in this embodiment, each of the plurality of shielded plywood panels 27 is fixed to the lightweight shaped steel 25 via the locking member 16 provided on the shielded plywood panel 27 and the elongated steel 26. Since the light-weight shaped steel 25 itself can be installed at any position as long as it is between the floor slab 18 and the ceiling slab of the building, the outer periphery of the electromagnetic shielding room formed by combining the shield plywood panel 27 The electromagnetic wave shield room by making the most of the site area of the MRI examination room 1 by matching the shape of the part to an arbitrary shape, for example, a shape following the unique shape of the MRI examination room 1 or a desired rectangular shape Can be installed.

Moreover, the electromagnetic shielding metal foil 15 of the shielded plywood panel 27 includes a side projecting portion 15 a for electrically connecting to the electromagnetic shielding metal foil 15 attached to the surface of the adjacent plywood panel 14. Since the side projecting portion 15a can be freely bent and electrically connected to the electromagnetic shielding metal foil 15 attached to the surface of the adjacent plywood panel 14 by soldering, an MRI inspection room Even in the case where adjacent wall surfaces in FIG. 1 are abutted at an intersection angle other than a right angle, the electromagnetic shielding metal foil 15 can be easily stretched in the building without using an independent special connecting member. .
For example, the plurality of existing walls 9 defining the MRI examination room 1 are arranged in the clockwise direction in FIG. 1 as a first existing wall 9, a second existing wall 9, a third existing wall 9,. In this case, if the first existing wall 9 and the second existing wall 9 intersect at a right angle, the first existing wall 9 installed at a position adjacent to the second existing wall 9 is used. The side projecting portion 15a of the shielded plywood panel 27 is bent at a right angle and soldered to the electromagnetic shielding metal foil 15 attached to the surface of the plywood panel 14 of the second existing wall 9 adjacent thereto. For example, when the first existing wall 9 and the second existing wall 9 intersect at an acute angle (obtuse angle), the first existing wall 9 is installed at a position adjacent to the second existing wall 9. The side projecting portion 15a of the shielded plywood panel 27 of the first existing wall 9 has an acute angle (obtuse angle). The second electromagnetic shielding metal foil 15 stuck to the surface of the plywood panel 14 of the existing wall 9 adjacent by song Re 此 may be solder joints.

  Moreover, the electromagnetic shielding metal foil 15 is preliminarily pasted on the surface of the plywood panel 14 in the factory prior to the installation work, so that the series of plywood panels combined in the installation work of the electromagnetic wave shield room is large. It is not necessary to stick the metal foil for electromagnetic wave shielding of an area. Therefore, no special skill is required for the person in charge of the installation work on site, and no curing time is required to wait for the adhesive to harden, so the installation work can be completed in a short time. The labor of the person in charge is reduced.

  Further, even when the electromagnetic shielding metal foil 15 is attached to the plywood panel 14 using a volatile adhesive, the attaching work can be performed in advance in a factory where ventilation work is free. Since there is no need to perform the sticking work in the building where the ventilation is poor, there is no risk of adverse effects such as volatile solvents on the workers.

  In particular, the shield plywood panel 27 of this embodiment is provided with an upward projecting portion 15b for electrically connecting to the electromagnetic shielding metal foil 24 attached to the surface of the ceiling-side plywood panel 23. Further, it is not necessary to fold and install a tape-shaped electromagnetic shielding metal foil along the corner formed at the abutting portion between the shielded plywood panel 27 and the ceiling-side plywood panel 23, thereby further simplifying the soldering operation. Is done. The reason is that the upper projecting portion 15b is integrated with the electromagnetic shielding metal foil 15 of the shield plywood panel 27, and only the tip of the upper projecting portion 15b is attached to the surface of the plywood panel 23 on the ceiling side. This is because the electrical connection between the electromagnetic shielding metal foil 15 and the electromagnetic shielding metal foil 24 is completed by soldering to the metallic foil 24. (When a tape-shaped metal foil for electromagnetic shielding is installed along a corner formed at the abutting portion between the shielded plywood panel 27 and the ceiling-side plywood panel 23, one of the tape-shaped electromagnetic shielding metal foils is provided. The side of the shielded plywood panel 27 is soldered to the electromagnetic shielding metal foil 15, and the other side of the tape-like electromagnetic shielding metal foil is attached to the surface of the ceiling side plywood panel 23. It is inefficient because it must be soldered to

  Further, the shield plywood panel 27 of this embodiment is provided with a downward projecting portion 15c for electrically connecting to the electromagnetic shielding metal foil 20 attached to the surface of the floor-side plywood panel 19. Further, it is not necessary to fold and install the tape-shaped metal foil for electromagnetic shielding along the corner formed at the abutting portion between the shield plywood panel 27 and the floor side plywood panel 19, and the soldering work is further simplified. Is done. The reason is that the lower projecting portion 15 c is integrated with the electromagnetic shielding metal foil 15 of the shield plywood panel 27, and only the tip of the lower projecting portion 15 c is adhered to the surface of the floor side plywood panel 19. This is because the electrical connection between the electromagnetic shielding metal foil 15 and the electromagnetic shielding metal foil 20 is completed by soldering to the metallic foil 20. (When a tape-shaped metal foil for electromagnetic shielding is installed along the corner formed at the abutting portion between the shielded plywood panel 27 and the floor-side plywood panel 19, one of the tape-shaped electromagnetic shielding metal foils is provided. The electromagnetic foil shielding metal foil 20 is bonded to the electromagnetic shielding metal foil 15 of the shielded plywood panel 27 and the other side of the tape-like electromagnetic shielding metal foil is attached to the surface of the floor side plywood panel 19. It is inefficient because it must be soldered to

  Even if the metal foil 15 for electromagnetic wave shielding of the shield plywood panel 27 includes only the side projecting portions 15a, along the corner formed at the abutting portion between the shield plywood panel 27 and the plywood panel 23 on the ceiling side. The tape-shaped electromagnetic shielding metal foil is bent and installed, and both sides of the tape-shaped electromagnetic shielding metal foil are adhered to the surfaces of the electromagnetic shielding metal foil 15 of the shielding plywood panel 27 and the plywood panel 23 on the ceiling side. Soldering to each of the electromagnetic shielding metal foils 24, and bending the tape-like electromagnetic shielding metal foil along the corner formed at the abutting portion between the shielded plywood panel 27 and the floor side plywood panel 19 The electromagnetic foil shielding metal foil 15 of the shield plywood panel 27 is installed on both sides of the tape-shaped electromagnetic shielding metal foil. It is possible to install an electromagnetic wave shield room by soldered to each of the electromagnetic shielding metal foil 20 stuck to the surface side of the plywood panel 19.

  Here, as an example, a side projecting portion 15a for electrical connection with the electromagnetic shielding metal foil 15 attached to the surface of the adjacent plywood panel 14 is extended from the right side portion of the shield plywood panel 27. However, the side projecting portion 15 a may be extended from the left side portion of the shield plywood panel 27.

And finally, on the floor side plywood panel 19 to which the metal foil 20 for electromagnetic wave shielding is stuck, the plywood overlapping paste 33 is installed, and on the surface of the shield plywood panel 27 installed along the existing wall 9 A wood base 29 is attached, and an inner wall material 30 such as a vinyl cloth is attached through the wood base 29, while a wood base 31 is attached to the lower surface of the plywood panel 23 on the ceiling side, and a vinyl cloth or the like is attached through the wood base 31. A finishing ceiling 32 is attached.
Further, the outer peripheral portion of the long sheet 34 having a slightly larger area than the plywood overlap bonding 33 is polymerized on the lower end portion of the inner wall material 30, and the long sheet 34 is attached to the upper surface of the plywood overlap bonding 33. Work related to interior decoration.
Since the installation of the plywood stacking 33 and the long sheet 34 and the attaching work of the wood bases 29 and 31 and the inner wall material 30 and the finishing ceiling 32 are already known, detailed description is omitted here.

  Further, in an electromagnetic wave shield room such as the MRI examination room 1 shown in FIG. 1, it may be necessary to post-process an opening for the shield window 11 after the shield plywood panel 27 is installed. However, since the locking member 16 fixed to the back surface of the plywood panel 27 is made of wood that can be easily cut, the shield plywood panel 27 having the electromagnetic shielding metal foil 15 and the locking member 16 is used as a chain saw. It is possible to easily cut and cut by the above, and even when the dimensions of the shield plywood panel 27 are standardized, the air conditioning opening and other openings can be easily drilled by post-processing on site.
