Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure in which a light iron base material of a building made of lightweight steel frame is attached so as to be insulated from the body side.

[0002]

2. Description of the Related Art In a multi-story building made of steel or reinforced concrete, such as a building, when a wall is installed, a concrete wall or pillar on the side of the body is attached with a base material made of lightweight steel, and this base material is used for interior decoration. It is designed to mount a panel board.

[0003]

However, in such a conventional steel frame base material mounting structure, the lightweight steel frame to be mounted as the base material is directly fixed to the frame side and short-circuited to the frame steel frame or reinforcing bars. It is like this. At this time, since the steel frame and the reinforcing bar are grounded at the bottom, the light iron base material is electrically connected to the body side, and when the lightweight steel frame part used for the base material becomes long, the antenna function is improved. As a result, it resonates with a radio wave having a wavelength corresponding to ¼ of the length, and various radio wave obstacles occur.
Further, since the light iron base material is grounded via the steel frame and the reinforcing bar as described above, there is a problem that electric shock may occur in some cases.

In view of the above-mentioned conventional problems, the present invention prevents the base material from exerting an antenna function by mounting the light iron base material formed of lightweight steel frame while being insulated from the grounded body. It is an object of the present invention to provide an insulating structure of a light iron base material, which is intended to prevent electric shocks as well as to prevent electric shocks.

[0005]

In order to achieve the above object, the insulation structure of the steel frame base material of the present invention is such that a light iron base material formed of lightweight steel frame is attached to the skeleton side, and this light iron base material is used as an interior material. In the structure that attaches the panel board,
An insulator is partially interposed between the light iron base material and the side of the body, and an appropriate space is provided between the light iron base material and the body by the insulator, and the light iron base material and the insulation are provided. A bolt having a high-strength insulating material arranged at least on the back surface of the head penetrating the body is provided, and the light iron base material is fixed to the skeleton side at the insulating material arrangement portion via the bolt.

Further, it is desirable that the high-strength insulating material be integrally coated on the bolt.

Further, a tubular portion is formed on the insulator to cover the outer periphery of the insertion portion of the bolt, and the tip end of the tubular portion is projected from a bolt mounting hole formed in the light iron base material, and It is desirable that a tapered portion that gradually increases in diameter be formed near the head of the shaft portion of the bolt, and that the protruding portion of the tubular portion be pushed open by the tapered portion as the bolt is tightened.

[0008]

With the above structure, in the insulating structure of the light iron base material of the present invention, the light iron base material is partially bolted to the body side with the insulator interposed. At this time, an appropriate space is provided between the light iron base material and the side of the body to prevent the light iron base material from directly contacting the side of the body. Further, since the high-strength insulating material is disposed on at least the back surface of the head of the bolt, it is possible to insulate the bolt from the light iron base material when the bolt is screwed to the body side. Coupled with the fact that the insulator is interposed between the iron base material and the body side, the light iron base material can be reliably insulated from the body side. Therefore, since the light iron base material is prevented from being electrically connected to the grounded body side, it is possible to prevent the light iron base material from exerting an antenna function and to be electrocuted by the light iron base material. Can be prevented.

Further, by coating the high-strength insulating material integrally with the bolt, it is possible to reduce the number of parts when mounting the light iron base material.

Further, a tubular portion is formed on the insulator so as to cover the outer periphery of the portion through which the bolt is inserted, and the tip end of the tubular portion is projected from the bolt mounting hole formed in the light iron base material, and By forming a taper portion that gradually expands in diameter in the vicinity of the head of the shaft of the bolt and pushing the protruding portion of the cylindrical portion open with the taper portion as the bolt is tightened, With the protruding part of the tubular part pushed open on the front side of the light iron base material, this protruding part is sandwiched between the bolt head and the light iron base material, so that it is insulated from the light iron base material. The bond with the body can be performed more firmly.
