Abstract

PROBLEM TO BE SOLVED: To provide a pass-through structure across a fire compartment, capable of reducing transmission of heat caused by fire or the like from one side of the compartment of a structure with fire occurring or the like to another side of the compartment of the structure without occurrence of fire or the like, having excellent fire resistance and maintainability.SOLUTION: A pass-through structure across a fire compartment comprises at least piping passing through a through-hole across the compartment arranged at a partition part of a structure, an annular thermally-expansible fireproof sheet installed on the external surface of the piping, and a sealant which closes the gap between the through-hole and the thermally-expansible fireproof sheet along a plane in parallel with the surface of the compartment. The piping includes a synthetic resin member. The piping passes through the through-hole, with a predetermined spacing between the internal surface of the through-hole and the external surface of the piping.

Description

  The present invention relates to a fireproof compartment penetration structure.

Even when a fire occurs on one side of a partition part of a structure such as a building or a ship, a partition is usually provided on the partition part of the building or the like in order to prevent flames and smoke from spreading to the other side.
When piping is installed inside the building, it is necessary to provide a hole penetrating this section and to insert the piping through the through hole.
However, simply inserting a pipe through the through hole causes a problem that flame, smoke, etc. diffuse from one side of the compartment to the other through the through hole when a fire or the like occurs.

Various structures have been proposed to cope with this problem.
FIG. 18 is a schematic cross-sectional view for explaining a first conventional fireproof compartment penetration structure 300.
As shown in FIG. 18, a synthetic resin pipe 52 is inserted into a through hole 51 provided in the section 50, and a thermally expandable refractory material 53 is disposed on the outer surface portion of the synthetic resin pipe 52 inside the through hole 51. Furthermore, a first conventional fireproof compartment penetration structure in which a gap between the through hole and the thermally expandable refractory material is closed with a mortar 54 is known (Patent Document 1).
When the first conventional fireproof compartment penetration structure 300 is exposed to heat from a fire or the like, the thermally expandable refractory material 53 expands to form a thermal expansion residue and is softened by heat from the fire or the like. The synthetic resin pipe 52 is crushed by the thermal expansion residue. Since the through-hole 51 is blocked by the thermal expansion residue, it is possible to prevent the flame, smoke, and the like from diffusing from one side of the compartment to the other.
However, in the case of the conventional fire prevention compartment penetration structure 300 shown in FIG. 18, the synthetic resin pipe 52 that is inserted through the through hole 51 provided in the compartment 50 is fixed by the mortar 54. For this reason, there is a problem that it is not easy to replace the synthetic resin tube 52 even when a defect is found in the synthetic resin tube 52.

On the other hand, a structure in which a fixed conduit is installed inside the through hole and a synthetic resin pipe is inserted into the fixed conduit is also known (Patent Document 2).
FIG. 19 is a schematic cross-sectional view for explaining a second conventional fire prevention compartment penetration structure 310.
As shown in FIG. 19, a fixed conduit 62 is installed in a through hole 61 provided in the section 60, and a synthetic resin pipe 63 is inserted into the fixed conduit 62.
A sealing material 64 is installed at the opposite end of the through hole 61 where the fixed conduit is installed. A thermally expandable refractory material layer 65 is installed in an annular space between the inner surface of the through hole 61 and the outer surface of the synthetic resin pipe 63.
A gap 66 is provided between the thermally expandable refractory material layer 65 and the outer surface of the synthetic resin pipe 63.

  However, in the case of the second conventional fire prevention compartment penetration structure 310, the position of the synthetic resin pipe 63 that passes through the through hole 61 provided in the compartment 60 is fixed by the fixed conduit 62. For this reason, in the case of the second conventional fire prevention compartment penetration structure 310, there is a problem that the addition and removal of the synthetic resin pipe 63 is not easy.

  In order to cope with this problem, it is also conceivable to install a sheath tube called a sleeve in the through hole 61 of the section 60 in place of the fixed conduit 62. If the synthetic resin pipe 63 is inserted into the sleeve, the synthetic resin pipe 63 can be easily added and removed.

JP 2002-119608 A Special table 2010-530945

However, when a sleeve is used, heat such as a fire may be transmitted from one of the sections where a fire or the like is generated to the other of the sections where a fire or the like is not generated through the sleeve.
This heat causes new problems such as combustibles in a section where no fire or the like is ignited.
Furthermore, when the present inventors examined, even if it uses the thermally expansible refractory material which shows a favorable result in test results, such as a fire resistance test, the actual 1st conventional fire prevention division penetration part structure is used. I noticed that in some cases, the fire performance may not be sufficient.
The object of the present invention is to reduce the transfer of heat such as fire from one of the sections of a structure where a fire or the like has occurred to the other of the section of a structure where no fire or the like has occurred. Another object of the present invention is to provide a fireproof section through structure that is excellent in maintainability.

  As a result of intensive studies by the inventor in order to solve the above-described problem, a synthetic resin member-containing pipe is inserted through a through-hole of a compartment provided in a partition portion of a structure, A fireproof compartment penetration structure in which the synthetic resin member-containing piping is inserted through the through hole with a predetermined interval between the inner surface and the outer surface of the synthetic resin member-containing piping is suitable for the purpose of the present invention.

  The fireproof compartment penetration structure of the present invention uses piping including a synthetic resin member. Even when the synthetic resin member contained in the piping is deformed, melted, or burned out due to heat from a fire or the like, the annular thermally expandable fireproof sheet installed on the outer surface of the piping is expanded by the heat from a fire or the like.

On the other hand, in the case of the fireproof compartment penetrating structure of the present invention, the thermally expandable fireproof sheet and the inner surface of the through hole provided in the compartment are installed at a predetermined interval.
As a result, it is possible to avoid a case in which heat such as a fire is taken away by the compartments due to the existence of the compartments, and the heat-expandable fireproof sheet is not sufficiently expanded and the heat-expandable fireproof sheet does not expand. For this reason, the thermally expandable fireproof sheet used in the present invention smoothly expands in response to heat of a fire or the like, so that flames such as fire and smoke are prevented from spreading through the pipes and through the pipes. Heat can be prevented from being transmitted.

  Furthermore, since the fire prevention compartment penetration part structure of the present invention does not require fixing piping inside the through hole of the compartment, the piping can be easily replaced and expanded, so that maintenance management of the fire prevention compartment penetration part structure is also possible. It becomes easy.

  EXAMPLES Next, although this invention is demonstrated in detail based on drawing based on an Example, this invention is not limited at all by these Examples.

  Hereinafter, the piping 3 will be described based on a case similar to FIG. 1 in which the through hole 2 of the section 1 is horizontally inserted. However, the piping 3 is inserted through the through hole 2 of the section 5 vertically. 2 can also be formed in the same manner.

FIG. 3 is a schematic cross-sectional view showing the fireproof compartment penetration structure 100 according to the first embodiment.
In Example 1, the hollow wall 11 of a building is used as the section 1 provided in the partition part of the structure.
The hollow wall 11 is formed by installing two gypsum boards at a distance from each other.
A circular through hole 12 is provided in the hollow wall 11. The shape of the through-hole 12 is not limited to a circle and can be selected as appropriate.
As shown in FIG. 3, piping 13 is inserted through the through hole 12. The piping is formed of a cylindrical tube made of synthetic resin such as polyvinyl chloride.

The pipes 13 are inserted through the through holes 12 with a predetermined gap between the inner surface of the through holes 12 and the outer surface of the pipes 13.
A heat-expandable fireproof sheet 14 is annularly installed on the outer surface of the piping 13. The heat-expandable fireproof sheet 14 is formed by laminating an aluminum foil laminated glass cloth layer and a heat-expandable resin composition layer, and the aluminum foil laminated glass cloth layer with the heat-expandable resin composition layer inside. A heat-expandable fireproof sheet 14 is installed on the outer surface of the pipes 13 (not shown).
When the thermally expandable refractory sheet 14 used in the present invention is installed in the through hole 12, the outermost surface of the thermally expandable refractory sheet 14 is spaced from the inner surface of the through hole 12 by a predetermined distance. Installed.
Thereby, the said thermally expansible fireproof sheet 14 does not contact with the inner surface of the said through-hole 12, and when the fireproof division penetration part structure concerning this invention is exposed to heat, such as a fire, a fire etc. are made to the division 1. The heat is never taken away. For this reason, since the said thermally expansible fireproof sheet 14 expand | swells rapidly with the heat | fever of the said fire etc., the fireproof division penetration part structure which concerns on this invention is excellent in fire resistance.

  Further, the predetermined interval between the inner surface of the through hole 12 and the outer surface of the pipes 13 can be appropriately set according to the purpose and application of the fire prevention compartment through portion structure actually used. Is preferably within a range of 1 to 99% of the distance from the inner surface of the through-hole 12 to the center of gravity of the cross section obtained by cutting the through-hole 12 with respect to a plane parallel to the surface of the section 1. More preferably, it is within the range of 5 to 90% of the distance.

The thickness and thermal expansion ratio of the thermally expandable refractory sheet 14 can be selected on the basis of the size capable of closing the through hole 12.
Further, a gap between the through hole 12 and the thermally expandable refractory sheet 14 is blocked by a sealing material 15 installed outside the hollow wall 11 along a plane parallel to the surface of the hollow wall 11.
The sealing material 15 has fire resistance, and can block flames and smoke generated by a fire or the like.

FIG. 20 is a schematic cross-sectional view showing a state where the fireproof compartment penetration structure 100 according to the first embodiment is observed from a direction perpendicular to the compartment.
In FIG. 20, the through hole 12 provided in the hollow wall 11 is actually covered with the sealing material 15 installed around the pipes 13 without any gaps, so that it cannot be seen from the outside. For convenience of explanation, the through hole 12 is indicated by a broken line in FIG.

When the fireproof compartment penetration structure 100 according to the first embodiment is exposed to a flame such as a fire, the thermally expandable refractory sheet 14 forms a thermal expansion residue due to the heat of the fire or the like.
In the thermally expandable fireproof sheet 14, since the aluminum foil laminated glass cloth layer as the incombustible material layer is annularly disposed, the thermally expandable resin composition layer disposed inside the incombustible material layer is a thermal expansion residue. It expands toward the inside while forming.
