本発明は床、壁その他の建造物の隔壁に設けられるケー
ブル貫通部に関する。DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a cable penetration provided in a floor, wall or other bulkhead of a building.
［発明の技術的背量］
一般にビルその他の建造物の床にケーブルを貫通させる

ことが行われている。[Technical weight of the invention] Generally, when a cable is passed through the floor of a building or other structure, the cable is passed through a cable penetration hole provided in the floor, and then a fireproof bulkhead is installed between the floor and the cable. Formation is taking place.
このような耐火隔壁の形成方法としては、ＢＣＪ工法と
呼ばれる方法が知られている。As a method for forming such fireproof partition walls, a method called the BCJ method is known.

。In the BCJ construction method, the cable is first passed through the penetration hole in the floor, and then the cable penetration hole is covered from the underside of the floor with a fireproof plate made of calcium silicate that forms the cable insertion part, and this fireproof plate is used as the anchor bolt. It is fixed to the floor.

完成する。Next, rock wool is filled into the cable passage from the top side of the floor, and then covered with a fireproof board made of calcium silicate that forms the cable passage part from the top side of the floor.
This fireproof plate is fixed to the floor with anchor bolts, and fireproof putty is filled between the cable and the fireproof plate to complete the cable penetration.

なければならないため、床に対する施工も必要になると
いう欠点があった。[Problems in the background art] However, such conventional cable penetrations are mostly formed on-site, and work must be done from both the top and bottom of the floor, which makes work easier, and furthermore, Since anchor bolts had to be embedded in advance around the through-holes, there was a drawback that construction work on the floor was also required.

ての（幾能が低下するという欠点もあった。M/C cables are subjected to heat cycles during use, and the cables repeatedly expand and contract due to heat.As a result, when used for a long period of time, gaps may form between the cables and the fireproof putty, and between the cables and the rock wool. It also had the disadvantage of decreasing its functionality as a fireproof bulkhead.

着剤を用い−（繊維相互を結着させＣもよい。The heat insulating molded body 4 is formed by molding, for example, a press, using a fire-resistant amorphous fiber such as rock wool, and forming it into a cylindrical shape that is vertically divided into two parts that fit around the outer circumference of the -C cable 2. It is also possible to use a shape C that is simply pressure-molded, but if necessary, it is also possible to use a 'C* 8M 'j'i adhesive to bind the fibers together.

してもよい。Further, the foamable fireproof tape 5 is a glass tape or other inorganic tape coated with a heat-resistant foamable composition that foams due to high temperatures during a fire, on one or both sides, and is prevented from drying. Note that this foamable fireproof tape may be omitted if necessary.
このような発泡性組成物としては、例えば高分子エマル

支持作用が良好であるので特に本発明には適している。A corrugated metal tube 7 split vertically into two, whose inner grooves are coated and filled with foamable fireproof putty 6, is fitted onto the outer periphery of the foamable fireproofing tape 5, and fixed with a fixing fitting 8 made of, for example, aluminum. Although a smooth metal tube made of metal may be used, a corrugated metal tube has a good supporting effect and is therefore particularly suitable for the present invention.
符号９は、波付金属管７の両端を封止する耐火パテであ
る。この耐火パテ９は発泡性ぐある必要はない。Reference numeral 9 denotes fireproof putty for sealing both ends of the corrugated metal tube 7. This fireproof putty 9 does not need to be foamable.

ある。Therefore, even if a gap forms between the cable and the heat insulating molded body after long-term use, in the event of a fire, it will not be possible for the cable to be damaged. In this embodiment, an example was explained in which a heat insulating molded body and a metal tube on the outer periphery were split vertically into two. However, since the effect of the present invention is exhibited in the event of a fire, it is also possible to use a cylindrical shape that is not split into two.
