Description of the Related Art A fireproof compartment penetrating member is used to prevent flame, gas, black smoke, etc. from spreading through a through hole such as a pipe or cable provided in the fireproof compartment when a fire occurs. It is attached to a pipe or a cable at the through hole. Then, when a fire occurs, this fireproof compartment penetrating member thermally expands due to its heat and closes the inside of the through hole, and the material is heat-expandable graphite or heat-expandable rubber or heat-expandable resin. It is used.

とから取り付けるため、製造に手間がかかる。The conventional fire compartment penetrating member is housed in a metal case having a square shape or a circular shape. In addition, as for a simple structure, the applicant of the present invention is Japanese Patent Application No. 8-245.
No. 833 is pending. The fireproof partition penetrating member in this application is a one-touch type in which a thermal expansion material is mounted in a C-shaped elastic metal plate. However, although this fire protection compartment penetrating member is easy to mount, it takes time and effort to manufacture because the thermal expansion material is mounted later in the metal plate.

る。Therefore, the applicant of the present invention has made a long-slit cylindrical body into a ring slice so as to reduce the cost as much as possible, and at the same time, to install it with a split groove, in a fireproof compartment. Japanese Patent Application No. 2000-92609 (Japanese Patent Application Laid-Open No. 2001-280550) is pending for the penetrating member.

間がかかって面倒である。However, in this fireproof compartment penetrating member, the thermal expansion material is extruded from the extruder to form a cylindrical long body, and this is cut into slices. If the material lacks elasticity or if a metal plate is attached to the surface, it is necessary to attach the metal plate later. Also, in this fire compartment penetrating member, the split groove is 1
Because it is only formed in the book, when mounting on the pipe,
Although it is necessary to open the split groove to a size that allows this pipe to pass through, both hands must be used to open the split groove to the outside diameter of the pipe, and mounting is very troublesome. Furthermore, when removing from the pipe, a driver or a dedicated opening tool has to be inserted into the split groove, which is troublesome and troublesome to remove.

If it is larger than that, it will not shift after it is installed. However, if the outer diameter of the pipe to be mounted is smaller than the inner diameter of the penetration member for the fire protection compartment, the position is not fixed during the construction because it is in a so-called loose state. In particular, if it is attached to a vertical pipe, it may fall downstairs due to gravity, so at this time it is necessary to temporarily fix it until it is treated with mortar or putty. Takes a lot of work. In addition, it is necessary to prepare a large number of partition penetrating members having different sizes, which increases the number of types and increases the production unit price.

Open from the cut side. Then, when the fireproof partition penetrating member is pressed against the pipe or the like while being slanted along the split groove, the split groove gradually opens from the side that is diagonally cut, so that the pipe or the like easily fits inside. When removing, the fire protection compartment penetrating member is pulled away from the pipe introducing portion side. If the cylindrical body has an elliptical shape, the applicable range is more than the pipe to be attached, which has the same outer diameter as the small diameter part, and the cylindrical body can be opened by the split groove. The allowable range for use is up to the outer diameter.
