Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a penetration part of a fireproof compartment arranged in a through hole of a conduit formed in the penetration part of the fireproof compartment to connect a conduit member made of a thermoplastic synthetic resin material. The present invention relates to a joint, a fire protection equipment, and a fire protection structure.

[0002]

2. Description of the Related Art A fireproof section is a partition (slab) on the upper and lower sides of a floor, a ceiling, etc., and a left and right side of a wall, etc. in an apartment building, and refers to a partition which should not spread fire when a fire breaks out. Therefore, JIS A1304 requires a structure in which the surface temperature on the side where the spread of the partition occurs is 260 ° C. or less, which is the wood ignition temperature.

As a conventional technique relating to such a fireproof compartment penetrating portion, there is, for example, one disclosed in Japanese Utility Model Laid-Open No. 6-7755. That is, the publication discloses a fireproof structure for suppressing the propagation of flames between the chambers on both sides of the fireproof compartment. The fireproof structure is equipped with a refractory thermal expansion material as a retrofit so that the pipe member made of a combustible thermoplastic material such as vinyl chloride is wound around the pipe member at the portion penetrating the penetration section of the fireproof compartment. On the other hand, in the event of a fire, the thermal expansion material expands due to the heat of the fire and blocks the pipeline, blocking both sides of the compartment.

The way of mounting is to wrap a pipe member with a fire resistant expansive material and cover it with an expansion holding member which is a separate member for holding it.

[0005]

However, in such a conventional technique, since the pipe member is limited to the case where the pipe member penetrates the penetration portion of the fire protection compartment, it cannot be used as a joint, and it is easy to use. There was a problem that there is a bad case.

Further, the expansion holding member, which is a separate member, has to have a special structure in order to hold a thermal expansion material having no strength since it is attached to the pipe member later, and the cost of the member is high. There is a problem in that it becomes expensive and costs a lot because of the number of man-hours required for construction.

The present invention has been made by paying attention to the problems of the prior art as described above, and is not limited to the case where the pipe member penetrates the penetration portion of the fire protection compartment, but is also used for the joint. It is also an object of the present invention to provide a joint for a penetration portion of a fireproof compartment, a fireproof structure, and a fireproofing equipment, which is easy to use, easy to handle and easy to construct, and can be reduced in cost as a member in construction.

A pipe line formed by the pipe line members P, P made of a thermoplastic synthetic resin material and the joint 1 penetrates through the through hole F1, and the joint 1 is arranged in the through hole F1 and then the joint is formed. 1 has a fireproof structure in which a gap between the through hole F1 and the through hole F1 is closed by a fireproof filler S.

The joint 1 is formed by covering a synthetic resin core tube 20 with an outer coat layer 30 made of a non-metal non-combustible material, and the middle portion 11 of the joint 1 has the same inner diameter as the conduit member P. Connection ends 12 to which a horizontal pipe similar to the pipe member P is connected are formed laterally from the intermediate portion 11, and connection ends 14 and 15 to which the pipe members P and P are fitted are formed above and below. ing.

The core tube 20 is generally made of vinyl chloride material, but other synthetic resin such as polypropylene may be used. The jacket layer 30 is, for example, a fiber-containing mortar, and if one example of the composition is shown, it is a normal Portland cement 5
2%, aggregate 25%, inorganic fiber 20%, organic fiber 3%
It is. In addition, ceramic-based materials, cement-based materials, and other materials can be used.

A holding metal fitting 16 formed of a metal material having good heat conductivity is extended.

The holding metal fitting 16 forms a ring-shaped groove-shaped expansion holding portion 40 in which the conduit member P fits. The expansion holding portion 40 extends from the outer periphery of the end portion 35 of the jacket layer 30 and has a holding piece 41 formed by bending the tip toward the center side, and the holding piece 41 holds the holding piece 41 in a groove shape to prevent heat of a fire. A refractory thermal expansion member 45 is mounted which expands at 1 to block the conduit and prevent the flame from being transmitted.

The thermal expansion member 45 is formed by winding a mat-shaped or sheet-shaped member into a cylindrical shape.
The inner circumference is fitted around the entire circumference of the conduit by the outer fitting end 21 of the core tube 20 of the connecting end portion 15, and is indirectly fitted to the conduit member P.

The thermal expansion member 45 has several commercialized compositions, and has the composition and characteristics shown in FIG. 21, for example. The mat is a ceramic fiber composite and the sheet is a flame retardant rubber composite. There is also putty.

Further, as the thermal expansion member 45, there are the ones shown in FIGS. 22, 23, and 24 disclosed in "Building Letter" magazine published by the Japan Building Center, manufactured by Furukawa Material Co., Ltd. Trademarks such as Danseal D, Danseal P, and Danseal FT are attached respectively.

Next, the operation will be described. The joint 1 of the fireproof compartment penetrating portion A is used by being disposed in the through hole F1 of the pipeline formed in the fireproof compartment penetrating portion A. The joint 1 is used for building piping or the like made of a thermoplastic synthetic resin material. The conduit members P, P are connected from above and below. Since the core tube 20 made of synthetic resin is covered with the jacket layer 30 made of a non-metal non-combustible material, the conduit member P is fitted to the outer fitting end 21 of the core tube 20 at the time of construction.

Since the joint 1 is covered with the covering layer 30 made of a non-metal non-combustible material, it does not burn by itself with a flame. A fire resistant thermal expansion member 45 mounted on the expansion holding portion 40 of the connection end 15 with which the conduit member P is fitted.

That is, when a fire occurs and a thermal state in which there is a risk of fire spread, the thermal expansion member 45 expands due to the heat of the fire and blocks the pipeline. As a result, the conduction between the fireproof compartments is cut off so that the flame is not transmitted and the spread of fire is prevented.

The ring-shaped groove-shaped expansion holding portion 40 is used as the outer cover layer 3.
However, in the present embodiment, the covering layer 3 is formed.

When a fire occurs in one of the fireproof compartments, and the fire spreads and there is a risk of fire spreading through the penetration portion A of the fireproof compartment, as shown in FIG. Starts to soften, and the core tube 20 of the joint 1 also starts to soften. This heat is also transmitted to the outside of the expansion holding portion 40 of the thermal expansion member 45, and when the temperature exceeds a predetermined temperature, the thermal expansion member 4
5 begins to expand.

The thermal expansion member 45 is in contact with the outer periphery of the conduit member P via the outer fitting end 21 of the core tube 20 of the joint 1,
As shown in (b), the thermal expansion member 45

When the flame approaches and becomes extremely hot, the thermal expansion member 45 expands sufficiently to reach the center of the pipe, and the pipe is closed, as shown in FIG. 2 (c). At that time, the synthetic resin conduit member P is melted. Since the pipe is closed by the heat resistant thermal expansion member 45, the through hole F1 of the fireproof section closes the gap between the outer cover layer 30 of the joint 1 made of an incombustible material and the joint 1 and the through hole F1. It is blocked by the material S and the thermal expansion member 45, and is blocked so that the flame does not propagate beyond the fireproof section.

FIG. 3 and FIG. 4 show a second embodiment of the present invention. It should be noted that, in the following, the same types of parts as those in the first embodiment will be designated by the same reference numerals, and redundant description will be omitted.

In the present embodiment, the fire protection equipment 2 is combined with the ordinary joint 5 having the same structure as the joint 1 without the thermal expansion member 45, and the fire prevention equipment 2 and the ordinary joint 5 are connected to the through hole F1.
A fireproof structure is provided in which the gap between the joint 1 and the through hole F1 is closed by a fireproof filler S after being disposed inside.

The ordinary joint 5 is formed by covering a synthetic resin core tube 20 with an outer coat layer 30 made of a non-metallic non-combustible material, and a horizontal tube similar to the conduit member P is connected laterally from the intermediate portion 11. Is formed, and connection ends 14 and 15a to which the pipe line members P and P are fitted are formed above and below. At the connection end 15a, the core tube 20 and the jacket layer 30 have the same edge 1
It stops at 5b.

The fire protection equipment 2 is formed by covering the core tube 20 with an outer coat layer 30 made of a non-metal non-combustible material, has a connecting end 17a to the joint 5 and is fitted with a conduit member P. It has a connection hole 17. An expansion holding part 40 is provided around the connection hole 17 of the fire protection equipment 2, and the expansion holding part 40 is made of a fire-resistant material that expands due to the heat of the fire and closes the pipeline to prevent the flame from being transmitted. The thermal expansion member 45 is attached.

At the connection end 15 of the fire protection equipment 2, the jacket layer 30 is interrupted at the base of the connection hole 17, and the jacket layer 3
The base portion is externally fitted to the end portion 35 of No. 0, the holding metal member 16 formed of a metal material having good heat conductivity is extended, and the ring-shaped groove-shaped expansion holding member for fitting the pipe member P toward the center is held. The part 40 is formed. The thermal expansion member 45 is mounted so as to be held in the groove shape by the holding piece 41. The ring-shaped groove-shaped expansion holding portion 40 is arranged so as to protrude into the room from the surface of the fireproof compartment.

The thermal expansion member 45 is formed by winding a mat-shaped or sheet-shaped member into a cylindrical shape.
It may be putty-like. The inner circumference is externally fitted so as to wind the entire circumference of the conduit formed by the end portion of the core tube 20 forming the connection hole 17, and is indirectly fitted to the conduit member P.

Usually, the joint 5 and the fire protection equipment 2 are connected via a connecting tube 6. That is, the outer fitting end 21 a is formed at the connecting end 15 a of the normal joint 5, and the outer fitting end 2 a is formed.
One end side 6a of the connecting cylinder 6 is fitted in the la 1a, and the other end side 6b projects from the outer fitting end 21a. The connecting end 17a of the fire protection equipment 2 is fitted to the other end side 6b to connect the fire protection equipment 2. The end portion P1 of the conduit member P fits into the connection hole 17.
A positioning rib 23 is provided at the center of the core tube 20 of the fire protection equipment 2 so as to protrude toward the center.

Next, the operation of the second embodiment will be described.
The fireproofing equipment 2 is applied to the fireproof compartment penetrating portion A for a pipe line that penetrates through a fireproof compartment made of a thermoplastic synthetic resin material. In the fire protection compartment penetration portion A, the fire protection equipment 2 is mounted so that the conduit member P fits into the connection hole 17. When a fire occurs and there is a risk of fire spread, the fire-resistant thermal expansion member 45 mounted around the connection hole 17 of the fire protection equipment 2 expands due to the heat of the fire and closes the pipeline. Prevent the flame from transmitting.

The fire protection equipment 2 has an outer cover layer 30 made of a non-metallic non-combustible material, and does not burn by itself in a fire. The fire-resistant thermal expansion member 45 attached to the connection hole 17 into which the conduit member P is fitted functions to prevent the spread of fire between the fireproof compartments when a fire occurs. That is, when a fire occurs and a thermal state in which there is a risk of fire spread, the thermal expansion member 45 expands due to the heat of the fire and blocks the pipeline. As a result, the conduction between the fireproof compartments is cut off so that the flame is not transmitted and the spread of fire is prevented.

The thermal expansion member 45 is preferably arranged so as to wind around the entire circumference of the pipe line. Therefore, the pipe-shaped member P fits into the connecting end portion 15 and is expanded and retained in the shape of a ring groove oriented toward the center. The portion 40 is provided to support the thermal expansion member 45.

The ring-shaped groove-shaped expansion holding portion 40 is used as the outer cover layer 3.
However, if it is formed of a metal material having good thermal conductivity extended from the outer cover layer 30, heat transfer to the thermal expansion member 45 is good and expansion is promoted. Also, a good heat transfer state can be obtained by disposing the ring-shaped groove-shaped expansion holding portion 40 so as to project into the room from the surface of the fireproof compartment. The fire protection equipment 2 is used by arranging it in the through hole F1 of the penetration portion A of the fire protection compartment and then closing the gap between the fire protection equipment 2 and the through hole F1 with the fire resistant filler S.

The state in which the conduit is closed by the thermal expansion member 45 will be described in more detail with reference to FIG. In the normal state shown in FIG. 3, the pipeline is connected by the normal joint 5 and the fire protection equipment 2 at the penetration portion A of the fire protection compartment, and the normal joint 5 and the fire protection equipment 2 are arranged in the through hole F1 through which the pipeline is passed. In addition, the gap between the joint 1 and the through hole F1 is closed by the refractory filling material S, and the pipeline is used for drainage or piping.

When a fire occurs in one of the fireproof compartments and the fire spreads and there is a risk of fire spreading through the penetration portion A of the fireproof compartment, as shown in FIG. As a result, the core tube 20 of the fire protection equipment 2 also begins to soften. This heat is applied to the expansion holding portion 40 of the thermal expansion member 45.
The thermal expansion member 45 starts to expand when the temperature exceeds a predetermined temperature.
