Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an electromagnetic wave absorber mounting structure, and more particularly to an electromagnetic wave absorber mounting structure capable of sufficiently crimping and holding an electromagnetic wave absorber on a wall of a shield room in a stable state.

[0002]

[Prior Art]

 Conventionally, as a structure for mounting a radio wave absorber on a wall surface of a shield room, for example, as shown in FIGS. 7 and 8, a radio wave absorber 1 having a pyramid or a wedge portion on the surface is provided with an adhesive 6 on a wall surface 2 of the shield room. At the time of attachment via a bar, a rod-shaped body 4 such as a resin pipe is arranged between the concave portions 3 on the surface, and the rod-shaped body 4 is fixed to the wall surface 2 of the shield room by a string 5 having one end fixed.

[0003]

[Problems to be solved by the device]

 However, since the string 5 is used for the fixing means as described above, the string 5 itself stretches and the fixing strength changes with time, and the mounting surface of the radio wave absorber 1 is loosened and the wall surface 2 of the shield room is removed. There is a problem in that the back surface of the radio wave absorber 1 is separated from the back surface, the workability of mounting is poor, and the radio wave absorbing performance is deteriorated.

The present invention has been devised in view of the above-mentioned conventional problems, and it is possible to sufficiently crimp and hold the electromagnetic wave absorber on the wall of the shield room, and improve the stability after installation and workability of installation. It is an object of the present invention to provide a mounting structure for a radio wave absorber that can be used.

[0005]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, this invention vertically implants a rod-shaped body having a low dielectric loss factor at a predetermined interval on the wall surface of the shield room, and at the same time, the dielectric loss factor is provided between the recesses on the surface of the electromagnetic wave absorber. A low-retaining rod-shaped member is arranged laterally orthogonal to the rod-shaped member, and the tip of the rod-shaped member is inserted into a through hole formed in the rod-shaped member, and is fastened and fixed via a locking member. This is the summary.

[0006]

[Function of the device]

 This invention is configured as described above, and when the electromagnetic wave absorber is fastened and fixed to the wall surface of the shield room, it is fixed by the rod-shaped body with a low dielectric loss factor and the locking member, so Can be sufficiently crimped and held on the wall surface of the shielded room without loosening, which can significantly improve the installation workability and improve the stability after construction, thus reducing the electromagnetic wave absorption performance. It can be worn without being forced to wear it.

[0007]

[Example of device]

 An embodiment of the present invention will be described below with reference to the accompanying drawings. The same components as those of the conventional example are designated by the same reference numerals and the description thereof will be omitted. 1 to 3 show a first embodiment of the present invention, and FIGS. 4 to 6 show a second embodiment of the present invention.

In the first embodiment of the present invention shown in FIGS. 1 to 3, the electromagnetic wave absorber 1 having a pyramid or a wedge portion on its surface is attached to the wall surface 2 of the shield room via the adhesive 6 in advance. On the wall surface 2 of the shield room, resin rods 7 having a screw portion 7a at the tip and having a low dielectric loss rate are vertically planted at predetermined intervals, and between the recesses 3 on the surface of the electromagnetic wave absorber 1. In addition, a restraining rod-shaped body 8 having a low dielectric loss rate is arranged in a lateral direction orthogonal to the rod-shaped body 7, and the locking member of the rod-shaped body 7 is fitted into a through hole (not shown) formed in the restraining rod-shaped body 8. The constituent screw portion 7a is inserted and tightened and fixed via a nut 9.

By fixing the radio wave absorber 1 to the wall surface 2 of the shield room by such means, the mounting strength of the radio wave absorber 1 is improved, and the workability is remarkably improved. In addition, in the second embodiment of the present invention shown in FIGS. 4 and 6, when the electromagnetic wave absorber 1 is attached to the wall surface 2 of the shield room via the adhesive 6, a pin is inserted into the wall surface 2 of the shield room in advance. Resin-made rod-shaped bodies 7 having a low dielectric loss rate and having holes 7b are vertically planted at a predetermined interval, and restraining rod-shaped bodies 8 having a low dielectric loss rate are provided between the concave portions 3 on the surface of the radio wave absorber 1. Is arranged in a lateral direction orthogonal to the rod-shaped body 7, and the pin 10 which constitutes the locking member by inserting the tip end portion of the rod-shaped body 7 into a through hole (not shown) formed in the holding rod-shaped body 8 is formed. It is fixed through.

[0010]

[Effect of the device]

 This device is As mentioned above, on the wall of the shield room, The rod-shaped bodies with a low dielectric loss rate are vertically planted with a predetermined space between them. Between the recesses on the surface of the radio wave absorber, a suppressing rod-shaped body having a low dielectric loss rate is disposed laterally orthogonal to the rod-shaped body, In the through hole formed in this restraining rod, Insert the tip of the rod-shaped body, Since it was tightened and fixed via the locking member, Fully crimp the wave absorber on the wall of the shielded room, Can hold, It is possible to improve stability and workability after installation, When attaching the electromagnetic wave absorber to the wall surface of the shield room with an adhesive, Until the adhesive hardens As a result, it can be held in a state of being crimped with the electromagnetic wave absorber, Workability has improved remarkably compared to the past. In addition, maintaining the electromagnetic wave absorption performance is also effective.
