Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This invention relates to the mounting structure of the radio wave absorber, and more specifically, the design relates to the mounting structure of the radio wave absorber. Radio wave absorption that can be firmly bonded and held on the wall of the cold room in a stable state. This relates to the mounting structure of the body.

0002

[Conventional technology]

Conventionally, as a structure for attaching a radio wave absorber to the wall of a shielded room, for example, As shown in FIGS. 5 and 6, a radio wave absorber 1 having a pyramid or wedge portion on its surface is When attaching to the wall 2 of the shield room with adhesive 6, the resin is placed between the recesses 3 on the surface. A rod-shaped body 4 such as a pipe made of It was fixed by a string 5 (or a rod-shaped body) with one end fixed to.

0003

[Problem that the invention attempts to solve]

However, when installing a radio wave absorber with a smooth surface, the rod-shaped body 4 as described above is used. There is a problem that the cables get in the way of construction, and the use of strings 5, etc. on the rod-shaped body 4 to absorb radio waves. When the storage object 1 is fixed, the string 5 will stretch over time and the mounting surface of the radio wave absorber 1 will become loose. The wall 2 of the shield room and the back of the radio wave absorber 1 are spaced apart, improving radio wave absorption performance. The problem was that it made things worse. Moreover, the rod-shaped body 4 exposed on the surface of the radio wave absorber is There was also the problem that they were not aligned and the appearance was bad.

0004 This idea was devised by focusing on such conventional problems, and it Can be sufficiently crimped and held on the wall of the cold room, improving stability after construction. It is possible to install a radio wave absorber that can maintain sufficient radio wave absorption performance. The purpose is to provide a mounting structure.

[0005]

[Means to solve the problem]

In order to achieve the above purpose, this idea has a threaded part at the tip on the wall of the shield room. The formed rod-shaped body is implanted, and the rod-shaped body is inserted through the through hole formed in the radio wave absorber. At the same time, a crimping member with a concave cross section is inserted into the tip of the rod, and the crimping part is tightened with a nut. The main idea is to tighten and fix the radio wave absorber to the wall of the shield room through the material. It is something that

[0006]

[Effect of invention]

This idea is constructed as described above, and the radio wave absorber is fastened to the wall of the shield room. When attaching and fixing, it is tightened and fixed with a nut through a crimp member with a concave cross section. , the radio wave absorber can be sufficiently crimped and held on the wall of the shield room, resulting in stability after installation. It is also possible to improve the radio wave absorber by attaching it to the wall of the shield room through adhesive. When adhering to a surface, the wall of the shield room and the radio wave absorbing It can be held in a crimped state with the body, improving workability.

[Example of idea]

Hereinafter, embodiments of this invention will be described based on the accompanying drawings. Note that the same components as those in the conventional example are given the same reference numerals, and the description thereof will be omitted. Figure 1 shows a state in which a radio wave absorber 1a with a smooth surface is attached to a wall 2 of a shield room. FIG. 2 is a cross-sectional view taken along the line A-A in FIG. The surface 2 is engaged with a hook or eye bolt (not shown) fixed to the wall surface 2. Rod-shaped bodies 7 made of resin are implanted at predetermined intervals, and a screw is attached to the tip of the rod-shaped body 7. A diagonal portion 7a is formed.

[0008] The rod-shaped body 7 is inserted through the through hole 8 formed in the radio wave absorber 1a, and the radio wave absorber 1a is inserted through the through hole 8. The portion protruding from the surface of the absorbent body 1a has a concave cross section as shown in FIGS. 3 and 4. The formed arch-shaped crimping member 9 is inserted through the through hole 10, and the tip of the rod-shaped body 7 is shaped. A nut 11 is screwed into the threaded portion 7a, and the radio wave absorber 1a is attached via the crimp member 9. is tightened and fixed to the wall surface 2 of the shield room. Note that the crimp member 9 is Similar to the rod-shaped body 7 above, it is made of synthetic resin material that does not affect the radio wave absorption performance. physically formed.

[0009] As described above, in this invention, a plurality of The rod-shaped body 7 of the book is inserted through the through hole 8 formed in the radio wave absorber 1a, and the radio wave absorber is further absorbed. An arch-shaped pressure bonding member 9 is formed with a concave cross section on a portion protruding from the surface of the body 1a. The nut 1 is inserted through the through hole 10 and attached to the threaded portion 7a formed at the tip of the rod-shaped body 7. 1 and attach the radio wave absorber 1a to the wall surface 2 of the shield room via the crimp member 9. Since it is tightened and fixed, the radio wave absorber 1a is sufficiently crimped to the wall surface 2 of the shield room. It can be maintained and the stability after construction can be improved. In addition, when the radio wave absorber 1a is bonded to the wall surface 2 of the shield room via adhesive, If the adhesive is hardened, the wall 2 of the shield room and the radio wave absorber 1a may be It can be held in a crimped state and workability is significantly improved.

[Effect of the idea]

This idea is based on a rod with a threaded end formed on the wall of the shield room as described above. A rod-shaped body is implanted, and the rod-shaped body is inserted through a through hole formed in the radio wave absorber, A crimp member with a concave cross section is inserted into the tip of the rod, and a nut is used to insert the crimp member through the crimp member. Since the radio wave absorber is tightened and fixed to the wall of the shield room, it can be It is effective. (a). When tightening and fixing the radio wave absorber to the wall of a shielded room, the pressure Since it is tightened and fixed with a nut through the attachment member, the radio wave absorber can be placed in a shield room. It can be sufficiently crimped and held on the wall surface, has good stability after installation, and has no loss of radio wave absorption performance. It can be held without any damage. (b). When attaching the radio wave absorber to the wall of the shield room using adhesive, Keep the wall of the shield room and the radio wave absorber pressed together until the adhesive hardens. It can be held and work efficiency is improved. (c). There is no need to continuously arrange rod-shaped bodies on the surface of the radio wave absorber as in the past. Therefore, construction workability is good.
