Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a connection structure for a panel material for a shield room, which can connect panel materials in a good manner and can easily realize high electromagnetic shielding performance.
[0002]
[Prior art]
When creating a shield room in a room, it is common to use a panel material having electromagnetic shielding performance to form a floor surface, a wall surface of four circumferences, and a ceiling surface.
[0003]
The panel material can be connected in a required number by screwing a joint plate on the indoor side or the outdoor side or screwing a notch portion on the side end surface via a bolt.
[0004]
[Problems to be solved by the invention]
When such a conventional technique is used, the panel material uses bolts and is connected via joint plates or notches, so the adhesion of the connecting portion tends to be insufficient, and the head of the bolt protrudes indoors. It was difficult to attach an interior material made of an electromagnetic wave absorbing material, it was difficult to obtain sufficient electromagnetic shielding performance, and the surface appearance was not good.
[0005]
Therefore, in view of the problems of the prior art, an object of the present invention is to connect the panel material in a form-like manner by connecting flanges protruding from the panel material by connecting frames on the indoor side and the outdoor side. An object of the present invention is to provide a connection structure for a panel material for a shield room, which can easily realize a shielding performance.
[0006]
[Means for Solving the Problems]
The configuration of the present invention for achieving such an object includes a flange projecting in the connecting direction of the two panel members and a connecting bolt attached from the indoor side, but the flange is abutted in the same plane on the indoor side, And a pair of connecting frames that are sandwiched and connected from the outdoor side, and the flange is formed by overlapping the indoor side of the panel material and the surface material made of steel plates on the outdoor side and extending in the connecting direction. The gist of the present invention is that the channel material is made of a steel plate that forms an opening on the indoor side over the entire length.
[0007]
The connecting frame can be formed with flange portions on both sides of the opening.
[0008]
In addition, each connecting frame can form a gap for attenuation of electromagnetic waves that opens to the indoor side and the outdoor side, respectively, between the panel material and each flange. A gap for attenuating the electromagnetic wave opening in the outer connecting frame can be formed.
[0009]
Furthermore, a soft shield sheet material can be interposed between one or both of the connection frames and the flange.
[0010]
The connecting frame may form the same plane as the indoor and outdoor surfaces of the panel together with a removable cover member that closes the opening of the indoor connecting frame.
[0011]
[Action]
According to the configuration of the invention, the pair of connecting frames are connected to each other by connecting the flanges of the panel material in the same plane with the connecting bolts attached from the indoor side, sandwiched from the indoor side and the outdoor side, and connected to the indoor side. Together with the cover material that closes the opening of the frame, the same surface is formed on the indoor and outdoor surfaces of the panel material. That is, the panel material can be electrically and integrally connected through the flanges and the indoor and outdoor connecting frames sandwiching the flanges, and good electromagnetic shielding performance can be obtained. The connection bolt is screwed into the connection frame on the outdoor side from the indoor side in the connection frame on the indoor side through the opening of the connection frame on the indoor side, and is closed on the indoor side by closing the opening through the cover material. It is not exposed to any outdoor side.
[0012]
The flange formed by extending the surface material of the panel material is mechanically and electrically completely integrated with the surface material. At the connection portion of the panel material, both the indoor side to the outdoor side and the outdoor side to the indoor side Electromagnetic leakage can be minimized.
[0013]
By forming a gap between each connection frame and the panel material, a labyrinth for electromagnetic wave attenuation can be formed through the gap, and the electromagnetic shielding performance at the connection portion of the panel material can be improved. The gap is preferably formed to have a width of about 1 to 5 mm and a depth of about 20 to 30 mm or more.
[0014]
Each flange forms a labyrinth for attenuating electromagnetic waves by forming a gap via a sub-flange at each end, and can further improve the electromagnetic shielding performance at the connecting portion of the panel material. In this case, the gap should be about 1 to 5 mm in width, the depth should be about 10 mm or more, and less than half the thickness of the panel material.
[0015]
If a soft shield sheet material is interposed between the connection frame and the flange, the shield sheet material can uniformly and uniformly contact the connection frame and the flange. The arrangement pitch of the connecting bolts is preferably set to about 40 to 100 mm. If the arrangement pitch is smaller than 40 mm, the required number of connecting bolts becomes excessive and the assembling work becomes complicated. If the arrangement pitch is larger than 100 mm, the adhesion between the connecting frame and the flange is poor, and the electromagnetic shielding performance may be lowered. .
[0016]
The detachable cover material can simplify wiring work and maintenance inspection work when the inside of the connecting frame on the indoor side is used as a storage space for the wiring cable.
[0017]
