る。2. Description of the Related Art Heretofore, a well-established member has not been used as this kind of partition-piercing pipe member, but a pipe member to be piped through a partition wall forming a fire-prevention section by a method described below. Fire protection has been provided. That is, around the pipe material that is piped through the partition wall forming the fire prevention compartment, the partition pipe penetrating portion and a normal pipe portion connected to both ends thereof are formed as separate structures, and both of these connection portions are formed. Fire protection was applied throughout. A conventional structure will be described with reference to the drawings. FIG. 6 shows a conventional structure in which a piping material 2 is pierced through a partition wall 1 such as a fire wall or a floor. In the vicinity of the partition 1, a partition penetration part A whose outer wall is formed by a nonflammable sleeve 3 is provided, and normal piping parts B, B connected to both ends are provided. On the other hand, the normal piping portions B, B connected to the partition wall penetrating portion A are formed to have substantially the same diameter as the partition wall penetrating portion A. And the connection part C of both parts A and B is a non-combustible tape T,
It is coated in a double winding. The partition 1 and the sleeve 3
The space between them is backfilled with mortar or heat-resistant sealing material 7. With such a configuration, the entire piping material 2 between the normal piping parts B is fireproofed. However, in the above-described configuration, a complicated operation of covering the connection portion C with the non-combustible tape T is necessary, and particularly, the piping material 2 that is piped to a narrow corner portion or a ceiling portion at a high position is used in the above-described conventional configuration. When the fire prevention treatment is performed by the construction method, the coating work may be very complicated and workability may be poor. Therefore, the present applicant has proposed a device (Japanese Utility Model Application No. 1-1) capable of solving these disadvantages.
No. 17531) has been filed. That is, as shown in FIG. 7, this is a partition wall penetrating pipe member P composed of a noncombustible sleeve 3 and a pair of caps 4 and 4 attached to both ends of this sleeve 3, and penetrates the partition wall 1. When mounting the pipe member P on the pipe member 2 to be piped, caps 4 are attached to both ends of the sleeve 3 in a sealed state, and after the pipe member 2 is surrounded by the sleeve 3, the sleeve 3 and Partition wall 1 through which sleeve 3 penetrates
By simply filling the gap between them and the gap between the cap 4 and the pipe member 2 with the heat-resistant sealing material 7 or the like, the installation can be completed, and the pipe work can be completed without the complicated work of covering the incombustible tape T. It has been proposed that the fireproofing treatment of the material 2 can be performed and the fireproofing treatment can be easily performed even for the piping material 2 that is piped in a narrow corner portion or a ceiling portion at a high position.
Separately, as shown in FIG. 8, the piping member 2 penetrating the partition wall 1 and the partition wall penetrating piping member P are integrally assembled and unitized in advance, and this is inserted into the partition wall 1.
After that, it is proposed that the fireproofing can be performed by connecting the ends of the adjacent pipes 2 and the ends of the unitized pipes 2 by a simple joint or brazing.

的とする。However, in the above-mentioned partition-piercing pipe member which can solve the disadvantages of the prior art,
When filling the heat-resistant sealing material in the gap between the cap and the piping material, after the piping material is pierced through the sleeve in which the caps are attached to both ends in a sealed state, the operator is from the outside of the partition wall penetrating piping member, The heat-resistant sealing material is pressed into the gap between the cap of the partition wall penetrating piping member and the piping material, and the inner side of the gap is filled only by the feeling of the operator's hand and the appearance of the outer surface of the sealing material. Since it cannot be confirmed, it cannot be said that the heat-resistant sealing material can be surely filled uniformly over the entire circumference of the gap. Usually, in order to fill and seal the heat-resistant sealing material in the gap, it is necessary to have a predetermined thickness and depth, and if the thickness or depth is less than that, the sealing property is poor, for example,
There is a risk that smoke or air will easily pass through. However, in the above-mentioned case, even though the worker has filled the predetermined amount of the sealing material from the outside of the partition wall penetrating pipe member, the part with the gap is densely packed and the other part is sparsely dense. There is a risk of a thin film shape, which may cause a problem that the gap cannot be uniformly sealed in the circumferential direction. The present invention relates to a partition wall piping member that can easily perform fire protection of the piping material as described above, and has a heat-resistant sealing material in the gap between the cap and the piping material when the piping material is attached to the piping member. It is an object of the present invention to provide a partition wall penetrating pipe member that can be filled uniformly and reliably in the circumferential direction.

相互に確実に密接させることができる。[Function] A non-combustible cap is attached to both ends of the non-combustible sleeve in a sealed state, and a pipe material which is pierced through a partition forming a fireproof section is passed through the pipe insertion holes of the caps at both ends. Formed by the sleeve, a gap between partition walls penetrating the sleeve and a seal material filling recess formed on the inner cap side of the cap, and a pipe material and an inner peripheral surface of the outer cap. The heat-resistant sealing material is filled in the gap (hereinafter referred to as the sealing material filling space). By doing so, the pipe material can be surrounded by a fireproof material without any gap, and the fireproofing treatment can be performed. When the worker fills the heat-resistant seal material into the seal filling space, the seal material in the seal material filling space flows along the outer peripheral surface of the pipe material and the inner peripheral surface of the outer cap to form a recess in the inner cap. The sealing material is filled by coming into contact with the insertion portion. Therefore, when the operator presses and seals the sealing material until the operator feels it hits, the sealing material filling space can be filled without a gap. That is, only by filling the recessed portion of the inner cap with the seal material, the seal material in the rear direction and the pipe longitudinal direction can be surely brought into close contact with each other between the cap and the pipe member.

せることができる。[Effects of the Invention] Therefore, while realizing the partition pipe penetrating member that can easily perform the fire prevention treatment of the piping material penetrating the partition wall, the gap between the piping material and the cap can be sufficiently sealed. The heat-resistant seal material can be reliably filled, and the performance of the partition wall penetrating pipe member can be improved. or,
If the outer cap sufficiently surrounds the inner cap and the inner cap is not exposed on the outer surface, the inner cap can be made of an inexpensive material other than fireproof material, for example, resin other than fireproof material, and the outer cap can be inserted. By forming a large hole and variously forming the insertion hole of the inner cap in a shape corresponding to the outer diameter of the pipe material and the number of pipes, the outside of the pipe material surrounded by the partition penetrating pipe member is prepared. It can be easily dealt with according to the diameter and the number of pipes, and thus the economical efficiency and workability can be improved.

The partition wall penetrating pipe member P includes a cylindrical sleeve 3 made of slate,
The sleeve 3 is wrapped around the outer peripheral surface of the pipe material 2 and the non-combustible cap 4 which is attached in a sealed state over the entire circumference of the edge portions of the both ends so as to close a part of the openings at both ends.
The heat insulating material 5 made of foamed polyethylene is installed in the sleeve 3. As shown in FIG. 1, the cap 4 includes an outer cap 4B that fits over the entire edge of the sleeve 3 in a sealed state, and an inner cap 4A held between the inner surface of the outer cap 4B and the end edge of the sleeve 3. It consists of
The outer cap 4B is formed in a tubular shape, and the inner diameter on one end side is slightly larger than the outer diameter of the sleeve 3, so that this one end side is in a sealed state over the entire edge of the sleeve 3. It is configured so that it can be fitted over without any gap, and
An insertion hole 6 is provided in the center of the other end side for penetrating the piping material 2. The inner cap 4A is a plate-shaped disc, and an insertion hole 6 for penetrating the piping material 2 is arranged in the center of the inner cap 4A, and the peripheral portion of the insertion hole 6 has a two-step shape that is recessed in the sleeve longitudinal direction. When the dented portion is in a mounting posture in which the fireproof partition wall penetrating pipe portion P surrounds the pipe material 2,
It is configured to form a seal material-filling recess 4C that is recessed substantially along the axial direction of the sleeve 3. Therefore, when the partition wall penetrating piping member P is attached to the piping material 2 which is pierced through the partition wall 1, the partition wall 1 is first formed with an opening into which the partition wall penetrating piping member P can be inserted. Then, the partition wall penetrating pipe member P is inserted into this opening and is temporarily fixed appropriately. Next, the piping material 2 penetrating through the insertion holes 6 of both the inner and outer caps 4A and 4B of the partition wall penetrating piping member P and extending to the fireproof section is surrounded by the sleep 3, and the piping is performed.
Next, a gap is formed between the sleeve 3 and the partition wall 1 penetrating the sleeve 3, and is formed between the sealing material filling concave portion 4C of the inner cap 4A and the inner peripheral surface of the outer cap 4B and the piping material 2. The heat-resistant sealing material 7 is filled as a sealing material in the sealing material filling space. As described above, the pipe member 2 can be surrounded by the fire-resistant material without any gap, and the fire prevention processing can be completed. Therefore, the work can be easily performed. Then, when the worker fills the heat-resistant seal material 7 in the seal-material filling space, the heat-resistant seal material 7 in the seal-material filling space is easily and slightly filled with the heat-resistant seal material 7 in the recess 4C. By being pressed by the outer cap 4B, it flows along the outer peripheral surface of the pipe material 2 and the inner peripheral surface of the outer cap 4B, and abuts against the side wall of the seal material filling recess 4C of the inner cap 4A to be filled. Therefore, the heat-resistant sealing material 7 can be filled into the sealing material filling space without any clearance, and the clearance between the piping material 2 and the cap 4 can be reliably sealed.
