A plurality of panels formed of a ferromagnetic material, the other wall side of which is formed of a dielectric material, and a plurality of connection fittings for connecting the panels together to form a shield wall composed of the plurality of panels, Each connection fitting includes a pair of holding plates that are respectively in contact with the ferromagnetic body side wall surface and the conductor side wall surface of the panel along the edge of the panel, and connection means for fastening the pair of holding plates together. It is.

The side structure of a magnetically shielded room described in Japanese Utility Model Laid-Open Publication No. 6-12605 is such that a magnetically shielded panel is arranged inside a general partition panel, and adjacent left and right panels are connected via studs. At the upper and lower ends of the magnetic shield panel, joints are formed, and they are engaged with each other to form an upper and lower connection structure, which can be installed, dismantled or moved, and has high magnetic shield performance, and the attached magnetic shield The panel can be reused, and a magnetic shield panel having a preferable appearance as a shield room can be obtained.

[0004]

However, each of the above-mentioned shield panels is composed of a. A dedicated connection tool or connection means for connecting the panels is required. b. The latter shield panel has a structure in which a shield plate is attached to one side of a general partition, so the size of the shield panel is limited, making it difficult to configure a shield room of any size. is there. c. The latter shield panel body has a complicated shape and the manufacturing cost is high. d. The shape and structure of the partition are complicated, and there is a problem in uniting.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a plan view and a side view of a shield plate and a frame of a unit type shield panel, and FIG. 2 is an assembled state. FIG. 3 is a plan view and a sectional side view of the unit-type shield panel, FIG. 3 is an explanatory view of the assembly of the unit-type shield room, and FIG. 4 is an explanatory view of the assembly of the unit-type shield panel.

1 and 2, U denotes a unit-type shield panel, 1 denotes a square frame constituting the unit-type shield panel, and 2 and 3 denote shield plates attached to both sides of the frame. The frame 1 is made of a material such as a metal or a synthetic resin. The frame has a substantially U-shaped cross section, and is formed in a predetermined shape (a square here) through which a central portion 1a penetrates.
A step 1b having a depth substantially equal to the thickness of a shield plate to be described later is formed around both surfaces thereof, and a screw hole 1c for fixing the shield plate is provided.
A flange portion of a shield plate described later is fitted and fixed.

The shield plates 2 and 3 are standardized. The shield plates 2 and 3 have the same shape, and two adjacent sides have flange portions 4 fitted to the step portions 1b formed on the frame.
Are formed. The flange portion 4 is formed as a step portion 5 which is recessed by a plate thickness from the surface of the shield plate 2 so as to fit into the step portion 1b of the frame 1, and the shield plates 2 and 3 are formed around the frame. A screw hole 6 for fixing is formed. The shield plate 1 is made of a material that blocks radio waves or magnetism.

As shown in FIG. 2, the frame 1 and the shield plates 2 and 3 are arranged such that the flange portions 4 and 6 of the shield plates 2 and 3 provided on both sides of the frame do not overlap as shown in FIG. It is fixed using the screw holes locked to the shield plates 2 and 3. Other fixing means include welding,
Naturally, appropriate means such as bonding can be used. The shield plates 2 and 3 may be made of a material that blocks radio waves and magnetism, such as a material that blocks radio waves on both sides of the frame, a material that blocks magnetism on one side, and a material that blocks magnetism on both sides. The unit type shield panel U is used for a wall portion forming a shield room as shown in FIGS. 3 and 4, and the flange portions 45 of the shield plates 2 and 3 are connected to the step portion 1b of the frame 1 as shown in FIG. While assembling and fixing.

In the assembling, an L-shaped unit having a stepped portion as shown in FIG. 5 is used at the ridge portion where the walls contact each other, as shown in FIG. FIG. 5 is a three-sided view of the shield plate of the L-type unit and an assembled perspective view of the L-type unit. This L-type unit also has one frame and shields attached to both sides of the frame similarly to the flat plate-type shield panel. The flange 10b can be fitted to the step of the frame. In the case where the flange portion of the adjacent wall interferes with the flange portion of the L-shaped unit, one of the interference flange portions can be cut as necessary.

Further, a corner unit C having a shape shown in FIG. 6 having a step portion into which a flange portion of an L-shaped unit constituting each ridge portion can be fitted is used also at a corner portion where three walls abut. . FIG. 6 shows a three-sided view of the shield plate used for the corner unit and an assembled perspective view of the corner unit. This corner unit C is also composed of one frame and shield plates 11 attached to both sides of the frame, similarly to the flat unit-type shield panel U, and the flanges of the adjacent L-type units are fitted to the steps of the frame. It is a configuration that can be combined. In the case where adjacent flange portions interfere with each other, one of the interference flange portions can be cut as necessary.

By combining the unit-type shield panel, the L-type unit, and the corner unit C configured as described above, a shield room is assembled and configured as shown in FIG. FIG. 7 is a sectional view of the assembled state. As is apparent from this cross-sectional view, the adjacent shield plates have the front shield plate 2 and the rear shield plate 3 overlapped, and the ends of the shield plates are displaced in plan view as shown in FIG. Therefore, radio waves and magnetism do not enter the overlapping portion of the shield plate. In addition, since the adjacent shield plates are connected by providing a step, the surface of the shield room becomes flat. The shield plate and the frame are fixed by using screws, bolts and the like with the holes aligned. As shown in FIG. 4, when adjacent frames are fixed with bolts or the like, the strength of the shield room is increased. In addition,
A part of the wall constituting the shield room may be provided with a door for entering and exiting the shield room.

As described above, according to the present invention, a shield room can be easily constructed using a unit type shield panel. In the above embodiment, the frame is a square, but a rectangle and other polygons can be used. Further, the flange portion provided to protrude from the frame is not limited to two adjacent sides, but may be two opposite sides. In the above embodiment, the overlapping portions of the shield plates are formed so as to be on the inner side of the wall, but it is also possible that a step corresponding to the plate thickness appears on the front side. In addition, the present invention can be embodied in other various forms without departing from the spirit or main features thereof, and the above-described embodiments are merely exemplifications in all respects, and Not be.

[0016]

As described in detail above, according to the present invention,
Since a unit-type shield panel is used, a shield room can be constructed extremely easily. Since the unit type shield panel also uses a standardized frame and shield plate, the manufacturing cost can be reduced and the handling becomes easy. Panels can be connected easily. The size of the unit type shield panel can be freely selected only by changing the size of the frame and the shield plate. Units are easy to use because there is no need for a partition or the like. It has excellent effects.
