Description

[Detailed description of the device]

[0001]

[Industrial application]

 The present invention relates to a floor structure of a magnetic shield room and a magnetic shield panel used for the floor.

[0002]

[Prior Art]

 Similar to the radio wave shielded room that blocks the intrusion of radio waves, the magnetic shielded room that prevents the action of magnetism is widely used. The magnetic shield room may have a slightly rougher structure than the radio wave shield room, and a slight gap must be avoided there. Therefore, the performance (magnetic shield function) depends on the distance between the pitches of the screws attaching the panel. Does not mean that it will significantly affect.

By the way, in most conventional magnetic shielded rooms, a plate-shaped shield material is attached to a framed space with screws, nails, etc., and is attached not only to the side surface but also to the ceiling and floor surface. , It is designed to leave no gaps in the seams. However, such a construction method has a large number of on-site work factors, which causes variations in construction quality and adversely affects the shield performance. Since it is not an assembled room that is set as a set, the construction time is long and moving the magnetic shield room once installed is very troublesome. On the other hand, when the shield plate, which is attached to the side surface or the ceiling surface as well as the floor surface, is very expensive, when it is relocated, it will not be possible to leave marks on the shield plate such as screw holes. Remaining is difficult to reuse.

[0004]

[Problems to be solved by the present invention]

 As described above, the conventional type magnetically shielded room has the above-mentioned problems. The problems that the present invention intends to solve are these problems.The magnetic shield room is easy to install, can be easily disassembled and relocated, has high shielding performance, and has a good interior. The floor structure is targeted.

[0005]

[Means for Solving the Problems]

 The floor structure of the present invention is constructed by arranging magnetic shield panels attached on plywood while maintaining the continuity of the shield layer. The magnetic shield panel is bent vertically downward at its periphery to form an edge, and the lower end of the edge is further bent vertically to form the fastening piece and the overlapping piece horizontally. The fastening pieces are provided at opposite lateral edges and face each other outward, while the overlapping pieces are formed at the opposite longitudinal edges in the same direction. That is, one side is directed to the outside and the other side is directed to the inside, and the length of the edge having the inward facing overlapping piece is shortened by the plate thickness. Therefore, the bottoms of the fastening piece and the outwardly facing polymerized piece are on the same plane and coincide with the plywood bottom, but the thickness between the bottom of the inwardly facing overlapping piece and the plywood bottom is It leaves a minute gap.

By the way, since the magnetic shield plate configured as described above is arranged on the floor surface, a joint material is provided between the magnetic shield plates adjacent in the lateral direction, and the joint material presses the fastening piece. To fix. On the other hand, the vertically adjacent magnetic shield plates are arranged with their edges abutting each other and the overlapping pieces overlapping each other. Then, in order to maintain the continuity of the shield layer between the magnetic shield panel placed on the floor and the side surface, an L-shaped bent connection is brought into contact with and fixed to the magnetic shield panel on the side surface and the floor. .. Furthermore, a plywood is placed on the magnetic shield panel, and a floor sheet is attached to the upper surface of the plywood if necessary. Hereinafter, embodiments according to the present invention will be described in detail with reference to the drawings.

Are arranged in the horizontal direction and the vertical direction of the floor surface 6, but the joint materials 3, 3 are arranged between the magnetic shield panels 1, 1 ,. , And the magnetic shield panels 1, 1 ... Are screwed through the joint materials 3, 3.

FIG. 2 shows a specific example of the magnetic shield panel 1 of the present invention, and is a three-dimensional view from the bottom side. In this way, the magnetic shield panel 1 has edges 7, 7 ... Formed in its periphery, the edge 7 extends vertically downward with respect to the panel surface, and is the lower end of the edge 7 in the lateral direction (X-X direction). The fixing pieces 8 and 8 are horizontally extended outward, and the overlapping pieces 9 and 10 are horizontally formed in the vertical direction (Y-Y direction). The polymerized piece 9 extends outward, the other polymerized piece 10 faces inward, and the bottom surface 11 of the polymerized piece 10 is higher than the bottom surface 12 of the polymerized piece 9 by the plate thickness. ..

Showing. The magnetic shield panels 1 and 1 arranged in the lateral direction are provided with a joint material 3 between them, and by fixing the joint material 3 with a screw, the fastening pieces 8 and 8 are pressed and fixed. Although the shape of the jointing material 3 is not limited, the side pieces 15, 15 provided on the left and right sides press the fastening piece 8 while the side surface contacts the edge 7, and the distance between the magnetic shield panels 1, 1 is regulated. Control.

On the other hand, the magnetic shield panels 1, 1 arranged in the vertical direction have their edges 7, 7 abutting each other, and the overlapping pieces 9, 10 overlap each other. A gap corresponding to the plate thickness is left between the bottom surface 11 of the overlapped piece 10 and the floor surface 6, and the overlapped piece 9 is fitted into and overlaps with the gap. The shield angles 16 shown in FIG. 1 are fixed to the magnetic shield panels 1, 1 ... Arranged in this way and the side surfaces of the shield room to secure the continuity of the shield layer. Are brought into contact with the magnetic shield panel attached to the inside of the side surface and the magnetic shield panels 1, 1, ... On the floor surface.

[Effect of the device]

 The present invention arranges magnetic shield panels attached to the backing material on the floor surface and lays plywood on the upper surface to form a floor structure, and the installation work is extremely simple. In other words, the magnetic shield panel provided with the backing material is manufactured at the factory, and it is sufficient to bring it into the field, arrange it on the floor and fix it through the joint material, and disassemble and relocate it. It can be done easily. Furthermore, the standardized magnetic shield panel is only arranged on the floor and fixed by joints, so it can be reused after dismantling. On the other hand, the floor structure constructed by arranging the magnetic shield panels in this way has a high magnetic shield performance due to the continuous formation of the shield layer. The shield performance does not fluctuate.
