Abstract

PURPOSE:To abate an adverse effect to various apparatus due to jamming by interposing an electromagnetic wave absorbing shield sheet between the back of a wall or the like in a living space and a body. CONSTITUTION:In a structure such as a building, a house or the like made of wooden and steel, it is made up of interposing an electromagnetic wave absorbing shield sheet 19 between at least the back of an inner wall 10 in bodies 20 and each body 20 and surrounding the backside of a living space. With the above constitution, jamming is abatable up to 40dB or so, so that any type of noise- piano, din, rain noise or the like- will not come to nuisance against the living space.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a structure for suppressing radio interference to the inside and outside of a living space made of wood or steel.

(Prior Art) Conventionally, no measures have been taken to prevent radio wave interference in the residential environment of this structure.

[Problem to be solved by the invention]

However, in this type of structure, interference radio waves are emitted from glow discharge equipment, TVs, information processing equipment, and electronic office equipment from inside and outside the structure, and these can cause so-called radio wave interference that impairs the operation of IJ2 equipment. [Means for Solving the Problems] In order to eliminate such drawbacks, the present invention has the following disadvantages: This paper proposes a structure in which an electromagnetic wave-absorbing IS shielding sheet is interposed between the back surface of a wall or the like of a living space and the frame, thereby reducing the adverse effects of radio wave interference on various devices.

〔Example〕

Hereinafter, one embodiment of the construct according to the present invention will be described in detail using the drawings.

FIG. 1 is a schematic structural diagram showing an example of the present invention. The structure shown above is made of one of wooden and steel structures. Examples of wooden structures include passive air cycle structure, active air cycle structure, prefabricated structure, and 2×4 structure. , consisting of one of the frame structures. 2 is a roof, for example, as shown in No. 2171, roofing material 3
, waterproof sheet 4, roof board 5, rafters 6, etc., 7 is the attic space, 8 is the attic space (Q air volume, 9 is the ceiling board, 10 is the interior wall, 11 is the floor, 12 is the exterior wall, 13 is the interior) , space between outer walls, 1
4 is a living space, 15 is an underfloor space, 16 is a foundation, 17 is an underfloor ventilation opening, 18 is a dirt floor, 19 is an electromagnetic wave absorption shielding sheet (
(hereinafter simply referred to as a sheet), 20 is a frame consisting of pillars, studs, etc., 21 is the ground, and 22 is a waterproof and moisture-proof sheet.

To explain further, the earthen floor 18 is made of concrete, the ground as it is, or concrete from the upper layer, waterproof,
The moisture-proof sheet 22 and the ground 21 are arranged in this order.

In addition, the sheet 19 is made of stainless steel fiber, conductive polymer fiber, ferrite, ferromagnetic metal, conductive fiber, amorphous magnetic material fiber, graphite, or metal foil mixed, bound, or attached. Made of noncombustible sheet, synthetic resin sheet, etc., thickness is about 0.1~0°5H, width is 200~
It is 1000m penetration.

Of course, the metal foil etc. described above and the sheet-like material can also be formed integrally. The intervening position of the sheet 19 is at least between the frame 20 and the inner wall 10 as shown in FIG.
It is also placed between the floorboards and the joists. In particular, the sheet 19 is preferably made of a moisture-proof and breathable material.

〔Effect of the invention〕

As described above, according to the structure according to the present invention, (1) an electromagnetic wave absorbing and shielding sheet is interposed between the inner wall forming the living space and the frame, so that radio wave interference can be reduced by about 40 dB. ■
Piano, noise, rain sounds, etc. do not interfere with the living space. It has the following characteristics.
