【考案の詳細な説明】
本考案は建築物の壁、床等におけるケーブル貫
通部の構造に関するものである。[Detailed Description of the Invention] The present invention relates to the structure of a cable penetration part in a wall, floor, etc. of a building.
従来、耐火性と延焼防止の為、気密性を必要と

を詰めて防火構造とすることが一般に行なわれて
いる。 Conventionally, in order to provide fire resistance and prevent the spread of fire, cable penetration holes in walls of buildings that require airtightness are filled with asbestos, etc., and a fireproof plate is used as a restraining plate at the cable entrance and exit of the penetration hole. It is common practice to fill the space between the plate and the cable with a non-hardening putty-like flame retardant composition to create a fireproof structure.
しかしながらこのケーブル貫通部は構成工事に
工数と経費を用し、しかも貫通孔に直接付着した
難燃性パテ状組成物は経時的に容易に軟化したり
脱落のおそれもあり、又ケーブルが貫通している
中心部のケーブル周囲に詰められた石綿は気密性
に劣る為十分な延焼防止性能を有していなかつ
た。 However, this cable penetration part requires man-hours and expenses for construction work, and the flame-retardant putty-like composition directly attached to the penetration hole may easily soften or fall off over time, and the cable may not pass through the hole. The asbestos packed around the central cable had poor airtightness and did not have sufficient performance to prevent the spread of fire.

出来るが少量しか充填出来ない厚みのない壁には
不向きであつた。 On the other hand, in recent years, flame-retardant polysiloxane foam has been known to have a sealing effect in general fireproof compartments. Generally, it does not have the same fire-resistance performance as that of other materials, and it is necessary to use a large amount to ensure sufficient fire-resistance performance.It can be used for cable penetrations in thick walls, but it is not suitable for thin walls where only a small amount can be filled. Ta.

ケーブル貫通部となしたものである。 That is, the present invention coats the entire or part of the periphery of a cable with a highly thermally conductive electrical conductor located in the cable through hole with a putty-like flame retardant composition to impart strong fire resistance to the part. At the same time, the remaining part of the cable in the through-hole and the space other than the cable are airtightly filled with liquid flame-retardant polysiloxane, which hardens and foams after a certain period of time, so that the inside of the through-hole is filled with flame-retardant polysiloxane foam. By making it airtight, it can be used as a cable penetration part for walls, floors, etc., with excellent fire resistance and airtightness.

貫通孔出入口から貫通孔内部に向つて50ｍ／ｍ以
上あれば実用的には十分である。 In the present invention, when using a putty-like flame retardant composition, the fireproofing of the area around the cable is most important, so it is preferable to cover the entire length of the cable in the longitudinal direction inside the through hole. A distance of 50 m/m or more from the entrance/exit of the through-hole to the inside of the through-hole is practically sufficient.

A two-component curing type liquid flame retardant polysilicon composition such as -1900 is usually used. Polysiloxane foam usually exhibits an expansion ratio of 2 to 6 times, but it is preferable to use one having an expansion ratio of 3 to 4 times from the viewpoint of economy and fire protection. The liquid flame-retardant polysilicon composition may consist of a silicone compound alone, or may contain a powdered filler such as silica, clay, or calcium carbonate.
又、施工現場で容易に工事を行う為に該液状シ
