本考案は、ケーブル（電線）の耐火壁等の貫通

応しきれていなかつた。 Conventionally, for cable penetrations in fireproof walls, etc., the cable penetration hole in the wall was filled with a noncombustible material such as rock wool, and the openings on both sides of the through hole were closed with noncombustible plates (the noncombustible plate was made using supporting materials such as bolts). (installation),
The tiny gap between the noncombustible plate and the cable that passes through it was sealed with a flame-resistant sealant.
In the above-mentioned non-combustible sealed structure, once it is constructed, the non-combustible plate and non-combustible material cannot be removed unless the flame-resistant sealing material that has been filled with it is destroyed, and when resealing, the once-broken sealed part cannot be removed. It was necessary to prepare a new flame-resistant sealing material and recreate it, and the dismantling and resealing process required a large amount of man-hours and time, making it difficult to easily accommodate the need to add or relocate cables.
本考案は、上記した従来技術の問題点に鑑み、
不燃材の充填密閉とこれの取外しを著しく容易に

たものである。 In view of the problems of the prior art described above, the present invention
It is an object of the present invention to provide a penetrating portion of this type of cable through a fireproof wall, etc., which can be filled and sealed with a non-combustible material and removed, making it easy to accommodate the addition or relocation of cables.
即ち、本考案の貫通部は、不燃材料製袋に粉

するものである。 In other words, the penetrating portion of the present invention is constructed by inserting a large number of self-deformable bags made of noncombustible materials into a bag made of noncombustible material, filled with about 60 to 80% of amorphous noncombustible materials such as powder or fibers, and inserted into a fireproof wall, etc. The bag made of non-combustible material is loaded between the through-hole and the cable passed through the through-hole in such a manner that they are in close contact with each other so that they can be separated.
以下本考案の一実施例を添付図面を参照して説
明する。 An embodiment of the present invention will be described below with reference to the accompanying drawings.
耐火壁１にはケーブル３の径よりも充分に大き

材２には、不燃材料の袋２ｂに粉末、繊維等の不
定形不燃材２ａを60〜80％程度詰めて自己変形可
能にした袋詰め不燃部材として、これの多数個
２，２…をそれら袋２ｂ同志が離反可能に密着し
て充填してなるものである。 A through hole 4 having a diameter sufficiently larger than the diameter of the cable 3 is provided in the fireproof wall 1.
Through which the cable 3 is installed through the wall. Therefore, a noncombustible member 2 is used in the wall through hole 1 to fill and seal the gap between the cable and the cable. This is a self-deformable bag-packed noncombustible material filled with about 60 to 80% of the material, which is made by filling a large number of the materials 2, 2, etc. in close contact so that the bags 2b can be separated from each other.
袋２ｂへの不定形不燃材２ａの充填度を、60〜
80％程度とすることにより、不燃材２ａを詰めた
袋２ｂの自己形状変化の自由度を増して、ケーブ

できる。 The degree of filling of the bag 2b with the amorphous noncombustible material 2a is set to 60~
By setting it to about 80%, the degree of freedom in self-shape change of the bag 2b filled with the noncombustible material 2a can be increased, and the area around the cable 3 can be filled to seal the through hole 4.

における効果は大きい。 As described above, the penetrating portion of the present invention consists of a large number of self-deformable bag-packed noncombustible materials made by storing amorphous noncombustible materials such as powder or fibers that can be shaped into any shape in a noncombustible material bag. Since the bagging noncombustible members 2 are filled and sealed, it is extremely easy to seal the through hole by self-deformation of each bagging noncombustible member 2, and these bagging noncombustible members 2 are simply brought into close contact with each other with the bags 2b. can be removed from the through hole 4 as desired while still packed in a bag,
The through-hole can be sealed by simply repacking the bagging material, and therefore, adding or relocating cables can be easily accommodated by extremely simple measures such as attaching/detaching the bagging material and adjusting the number of cables. ,
The structure can also be greatly simplified. etc., the effect in reducing the number of work hours is significant.
