[Industrial application field]

This invention allows piping to penetrate through bulkheads that form fireproof partitions, such as firewalls and floors. The present invention relates to a partition wall penetrating piping member that protects piping materials.

0002

[Conventional technology]

Conventionally, established materials for this type of bulkhead penetrating piping have been used. Instead of installing piping through the bulkhead that forms the fireproof division using the construction method described below. Fire protection has been provided for piping materials used in the past few years. In other words, it penetrates the bulkhead that forms the fireproof compartment. The area around the piping material that is piped is the normal piping that connects to its bulkhead penetration and both ends. are formed as separate structures, and fire protection treatment is applied across both of these connections. It had been applied. A conventional structure will be explained based on the drawings. The conventional structure is shown in Figure 6. Here, piping material 2 is piped through a partition wall 1 such as a fire wall or floor. . In the vicinity of the partition wall 1, the outer wall is made of a non-combustible sleeve 3 that penetrates the partition wall. A section A is provided, and normal piping sections B and B connected to both ends are provided. one The normal piping parts B and B connected to this partition wall penetration part A have approximately the same diameter as the partition wall penetration part A. is formed. The connecting part C between both parts A and B is double-wound with non-combustible tape T. coated at the same time. Also, the space between the partition wall 1 and the sleeve 3 is covered with mortar or It is backfilled with heat sealing material 7. With this kind of configuration, the piping material between piping section B is usually The entire building was fireproofed. However, in the above configuration, the non-combustible tape T A complicated work is required to cover the connection part C, especially in narrow corners or in high positions. When fireproofing the piping material 2 installed in the ceiling using the above-mentioned conventional method, The coating work may be very complicated and have poor workability. Therefore, the present applicant has proposed a device (Utility Application Hei 1-1) that can eliminate these drawbacks. No. 17531) has been filed. In other words, this is a non-flammable three-dimensional structure as shown in Figure 7. It consists of a sleeve 3 and a pair of caps 4, 4 attached to both ends of the sleeve 3. The partition wall penetrating piping member P has a structure in front of the piping material 2 that penetrates the partition wall When installing the piping member P mentioned above, attach caps to both ends of the sleeve 3 in a sealed state. A sleeve 4 is attached, and after surrounding the piping material 2 with this sleeve 3, this sleeve 3 is attached. The gap between the rib 3 and the partition wall 1 through which the sleeve 3 passes, and the cap 4 and the piping material 2 The installation can be completed by simply filling the gap between the parts with heat-resistant sealant 7, etc. , the fire prevention treatment of the piping material 2 can be carried out without the complicated work of covering it with non-combustible tape T. For piping material 2 installed in narrow corners or high ceilings, We are proposing something that can be easily fireproofed. Also, as shown in Figure 8 The piping material 2 penetrating the partition wall 1 and the above-mentioned partition wall penetrating piping member P are assembled together, It is made into a unit in advance, which is inserted into the bulkhead 1, and then inserted into the adjacent arrangement. Connect the ends of the pipe material 2 and the ends of the unitized piping material 2 with a simple joint or filter. It has been proposed that fireproofing can be achieved by connecting them with a weld.

[Problem that the idea aims to solve]

However, in the above-mentioned partition wall penetrating piping member that can eliminate the drawbacks of the conventional technology, When filling the gap between the cap and the piping material with heat-resistant sealing material, seal at both ends. After passing the piping material through the sleeve with the cap attached, the operator From the outside of this bulkhead penetrating piping member, check the operator's hand feel and the appearance of the outer surface of the sealing material. Simply press the heat-resistant sealant into the gap between the cap of the bulkhead piping member and the piping material. It is made to close by basting, and the inside of the gap cannot be visually checked. Therefore, it is possible to reliably fill the heat-resistant sealing material evenly over the entire circumference of the gap. cannot be said. Normally, to seal the gap by filling it with a heat-resistant sealant, If the thickness and depth are required to be greater than the specified value, and if the thickness or depth is less than that, the They have poor sealing properties and may allow smoke and air to pass through them easily, for example. place In the above case, the operator fills the specified amount of sealant from the outside of the bulkhead penetrating piping member. However, the gap is filled with high density, and the other parts are filled with high density. There is a risk that the density will be sparse and it will form a thin film, so it is necessary to seal this gap evenly in the circumferential direction. There is a risk that a problem may occur where this is not possible. This invention is based on piping as described above. In bulkhead piping members whose materials can be easily fireproofed, the piping materials are attached to the piping members. Place a heat-resistant sealant around the gap between the cap and the piping material when it is attached. The purpose is to provide a bulkhead penetrating piping member that can be filled evenly and reliably in all directions. shall be.

0004

[Means to solve the problem]

The characteristic structure of the present invention in the partition wall penetrating piping member having the above structure is that the cap is removed. It is composed of a cap and an inner cap, and a shaft of the sleeve is attached to the inner cap. A recessed portion for filling the sealing material recessed approximately along the center direction is formed, and the recessed portion The point is that the insertion hole is arranged at the bottom of the entrance part.

[0005]

[Effect]

Attach a sealed nonflammable cap to each end of the nonflammable sleeve, and The piping material that passes through the bulkhead that forms the fire compartment is While passing through the tube insertion hole, surround the sleeve with the sleeve and the sleeve. a gap between the partition walls passing through the tube and a seal formed on the inner cap side of the cap; The gap formed by the material filling recess and the inner peripheral surface of the piping material and outer cap (hereinafter The lower sealant filling space (referred to as the lower sealant filling space) is filled with heat-resistant sealant. By doing so, Piping materials can be surrounded with fireproof materials without gaps, and fireproofing can be performed on them. and work When a person fills the heat-resistant sealing material into the sealing filling space, the inside of the sealing material filling space The sealing material flows along the outer circumferential surface of the piping material and the inner circumferential surface of the outer cap, and The sealant will be in contact with the concave part of the cup and will be filled. Press the sealant until you feel it fill, and the sealant filling space will be filled without any gaps. can be filled. In other words, just fill the recessed part of the inner cap with sealing material. Then, apply sealant between the cap and the piping member in both the rear direction and the longitudinal direction of the piping. It is possible to ensure that people are in close contact with each other.

[0006]

[Effect of the idea]

Therefore, it is possible to easily perform fire prevention treatment on piping materials that penetrate through the bulkhead. While realizing the pipe material, it is also possible to sufficiently seal the gap between the piping material and the cap. In addition, the gap can now be reliably filled with heat-resistant sealant, making it possible to securely fill the gap with the bulkhead-penetrating piping member. Performance can be improved. Also, the outer cap sufficiently surrounds the inner cap, and the inner cap If the structure is such that it is not exposed to the surface, the inner cap can be replaced with a non-fire-retardant inexpensive material, e.g. It can be made from resin other than fire-retardant materials, and the insertion hole of the outer cap can be made larger. Then, the insertion hole of the inner cap is shaped according to the outer diameter of the piping material and the number of piping. The outer diameter and arrangement of the piping material surrounded by the bulkhead penetrating piping member can be determined by forming and preparing the It can be easily adapted depending on the number of pipes, thus improving economic efficiency and workability. Wear.
