Description

  The present invention relates to a fireproof processing structure applied to a penetration portion of piping / wiring in a wall or floor that becomes a fireproof structure in a wooden building.

  The walls and floors constituting the fire-proof section in a wooden building have a fire-resistant structure in which a fire-resistant coating material such as gypsum board is attached to the outside of the base material. A decorative material, a decorative sheet, and the like are attached to the outside of the fireproof covering material as necessary. However, when installing pipes / wiring through such walls or floors, it is indispensable to perform fireproofing of the through-holes of the pipe / wiring. That is, in such a penetration part of the wall or floor, it is necessary to prevent the flame from entering the inside of the wall or floor from the penetration part and to prevent the flame from entering the other compartment through the penetration part. It is required to do. As a method to satisfy both requirements, the inside of the penetration part is made of non-combustible material such as gypsum board, and non-combustible material such as mortar is placed between the piping / wiring passed through the penetration part and the inner surface of the penetration part. There are processing structures to be filled. However, in such a processing structure, since the gypsum board or the like must be attached to the inside of the wall or floor, the opening of the penetrating part has to be relatively large, and thus the structure such as joists constituting the wall or floor. The position where the penetrating portion is formed has to be restricted due to the relationship with the arrangement of the materials. In addition, since it is difficult to minimize the distance between the penetrating part and the piping / wiring, when filling mortar between the two, a special curing process is required to hold it until hardening. By the way.

  The main problem to be solved by the present invention is that a fire-resistant treatment can be easily and appropriately applied to a through-hole of piping / wiring in a wall or floor that becomes a fire-resistant structure in a wooden building without impairing the fire resistance of the wall or floor. The point is to make it possible.

In order to achieve the above-mentioned object, in the present invention, the fireproof structure of the penetration part of the piping / wiring is a fireproofing structure of the penetration part of the piping / wiring in the wall or floor which becomes a fireproof structure in a wooden building. There,
The outer casing is provided with an outer casing on one end side of the tube, and is inserted into a through hole formed in the wall or floor constituent material from the one side of the wall or floor to the position where the outer casing is hooked and fixed on the outer casing, A metal sleeve body whose inside is a passage space for the piping and wiring;
An inner non-combustible material filled between the pipe / wiring passing through the sleeve body and the inner surface of the sleeve body;
An outer incombustible material filled between the through hole and the outer surface of the sleeve body is provided.

  According to such a fireproof processing structure, first, by simply forming a through hole having a minimum necessary size through which the sleeve body can pass through the wall or floor, the fire resistance of the wall or floor is affected. Piping and wiring can pass through this wall or floor without giving. Therefore, secondly, the position of the penetration part through which the piping / wiring passes is hardly influenced by the arrangement of the structural material constituting the wall or floor, and the installation position of the housing equipment etc. depending on such piping / wiring Can increase the degree of freedom. Thirdly, after the sleeve body is inserted into the through-hole, it is possible to easily and reliably impart fire resistance to the through-portion simply by filling the outer incombustible material and the inner incombustible material.

  On the other side of the wall or floor, the fireproof structure is further formed in an annular shape and a portion protruding to the other side of the wall or floor in the sleeve body inserted through the through hole to the position is passed through the inside. There may be provided a metal flange body fixed to the component.

  In addition, it is a preferable aspect of the present invention that the sleeve body is configured so that one end of the cylinder and the other end of the cylinder are positioned on the outer side of the outer surface of the wall or floor to be a fireproof structure. The

  According to the present invention, it is possible to easily and appropriately perform a fireproofing process on a through-hole of piping / wiring in a wall or floor having a fireproof structure in a wooden building without impairing the fire resistance of the wall or floor.

  A typical embodiment of the present invention will be described below with reference to FIGS. The fireproof processing structure according to this embodiment is applied to the through-hole H of the piping / wiring P in the wall W or the floor F that becomes a fireproof structure in a wooden building. That is, such a fire-resistant treatment structure is such that a wall W having a fire-resistant structure in which a fire-resistant covering material 2 such as gypsum board is put on the outside of the base material 1 of the wall W or a gypsum outside the base material 1 of the floor F. Through a floor F having a fireproof structure in which a fireproof covering material 2 such as a board is stuck, the wall W or the floor F is partitioned by the one side space (or one side section) to the other side space (or the other side section). Therefore, when the piping / wiring P is drawn into the wall W or the floor F, it is applied to the through-hole H formed on the wall W or the floor F. It is intended not to affect. That is, such a fireproof structure is a case where even if the penetration part H is formed in the wall W or the floor F, a situation in which a flame enters the inside of the wall W or the floor F, and fire spread. The situation that cannot be prevented by the wall W or the floor F is prevented from occurring.

  Such a fireproofing structure includes a sleeve body 3, an inner nonflammable material 4, and an outer nonflammable material 5.

  The sleeve body 3 is nonflammable and is made of a metal such as iron. The sleeve body 3 has both cylinder ends 3a and 3b open. In addition, the sleeve body 3 includes an outer casing 3c on the cylindrical end 3a side thereof, and a through hole Ha formed in the constituent material of the wall W or floor F from the one side of the wall W or floor F to the outer casing. 3c is inserted to a position where it is caught and fixed at the outer casing 3c, and the inside is used as a passage space for the piping / wiring P.

  In the illustrated example, the sleeve body 3 includes a cylindrical main body 3d having a cylindrical shape, and an outer casing structure body 3e that is combined with the cylindrical main body 3d to form the outer casing 3c. The thickness of the cylindrical main body 3d is preferably 0.5 mm or more. In the example shown in the figure, the cylindrical main body 3d is constituted by a metal plate 3h having a band shape spirally wound. In the drawing, reference numeral 3i denotes a gore fastening portion formed at the joint of the metal plate 3h constituting the cylindrical main body 3d. Further, the outer casing constituting body 3e is an annular plate that extends around one end of the short cylindrical body 3f having an inner diameter substantially equal to the outer diameter of the cylindrical main body 3d and projects outward from the one end of the cylinder. The part 3g is formed integrally. In the illustrated example, the short cylindrical body 3d and the cylindrical main body 3d are driven from the inside of the cylindrical main body 3d in a state where the cylindrical main body 3d is passed through the short cylindrical body 3f of the outer casing structure 3e. The screws 3j are fixed. The outer casing structure 3e is attached to a position biased toward one end of the cylindrical main body 3d. Thus, the sleeve body 3 is provided with the outer casing 3c on the cylinder end 3a side. It is sufficient that the cylindrical main body 3d and the outer casing structure 3e are fixed by welding or other known methods, and unlike the illustrated example, the outer casing 3c is formed integrally with the cylindrical main body 3d. It does not matter.

  The inner incombustible material 4 is filled between the piping / wiring P passing through the sleeve body 3 and the inner surface of the sleeve body 3. As the incombustible material 4, typically, rock wool, mortar, glass wool or the like can be used.

  The outer noncombustible material 5 is filled between the through hole Ha and the outer surface of the sleeve body 3. As the outer incombustible material 5, typically, a fire-resistant sealing material or the like can be used.

  First, the base material 1 (plywood or gypsum board in the illustrated example) as a constituent material of the wall W or floor F, and the fire resistance as a constituent material of the wall W or floor F that is stuck outside the base material 1 A through hole Ha constituting the through portion H is formed in each of the covering materials 2 (gypsum board in the illustrated example). The hole diameter of the through hole Ha is set to be slightly larger than the outer diameter of the sleeve body 3 and smaller than the outer diameter of the outer casing 3c. Next, the sleeve 3 is inserted into the through hole Ha of the base material 1 from one side of the wall W or the floor F to the position where the through hole Ha is caught. It adheres to the material 1. In the illustrated example, the outer casing 3c is fixed to the base material 1 by nails or screws driven into the base material 1 through the outer casing 3c. The outer casing 3c may be provided with a through hole such as a nail as necessary. Next, the fireproof covering material 2 is stuck so as to pass the sleeve body 3 through the through hole Ha of the fireproof covering material 2 as a constituent material of the wall W or the floor F. Next, the outer incombustible material 5 is filled from the outside of the wall W or the floor F between the through hole Ha of the fireproof covering material 2 and the outer surface of the sleeve body 3. At this time, on the fixed side of the outer casing 3 c, the outer casing 3 c serves as a filling bottom of the outer incombustible material 5. Finally, piping or wiring, or piping and wiring are passed through the sleeve body 3, and the inner nonflammable material 4 is filled between the inner surface of the sleeve body 3 and the piping / wiring P from the outside of the wall W or floor F.

  According to such a fireproof structure, first, the wall W or the floor F can be formed simply by forming the through hole Ha having a minimum necessary size through which the sleeve body 3 can pass through the wall W or the floor F. It is possible to allow the piping / wiring P to pass through the wall W or the floor F without affecting the fire resistance. Accordingly, secondly, the arrangement of the structural material constituting the wall W or the floor F is not easily affected by the position of the through-hole H through which the piping / wiring P passes, and the housing equipment depends on the piping / wiring P. It is possible to increase the degree of freedom of the installation position of equipment. Thirdly, after the sleeve body 3 is inserted into the through hole Ha, the through-hole H can be easily and surely provided with fire resistance simply by filling the outer incombustible material 5 and the inner incombustible material 4. it can.

  FIG. 2 shows an example in which a fire-resistant treatment structure is applied to the penetrating portion H of the floor F that becomes a fire-resistant structure. In this example, the sleeve body 3 is inserted through the through hole Ha formed in the base material 1 constituting the floor F to the position where the outer casing 3c is caught by the base material 1 from the other end 3b of the tube, and the base material 1 is inserted. After the outer casing 3c is fixed, the two fireproof coating materials 2 and 2 are put on the base material 1, and the two fireproof coating materials 2 and 2 (the ceiling and )). In this example, the sleeve body 3 has the cylinder one end 3a and the other cylinder end 3b positioned outside the outer surface of the floor F serving as a fireproof structure. Thereby, the flame that propagates along the outer surface of the floor F is prevented from being guided in the penetration portion H in the direction of entering the floor F. In this case, it is preferable that the total length of the sleeve body 3 is 350 mm to 420 mm, the distance from the cylinder end 3a to the outer casing 3c is 45 mm to 65 mm, and the distance from the outer casing 3c to the other end 3b is 305 mm to 355 mm. . If it does in this way, when the fireproof processing structure concerning embodiment is applied to the penetration part H of the floor F of general thickness, the cylinder one end 3a and the cylinder other end 3b of the sleeve body 3 will each be fireproof structure. It can be made to protrude in the range of 15 mm-20 mm from the outer surface of the floor F used.

  The fireproof structure is further formed in an annular shape, and a portion protruding to the other side of the wall W or the floor F in the sleeve body 3 inserted to the position where the outer casing 3c is hooked in the through hole Ha is formed on the inner side. It is also possible to include a metal flange body 6 that is fixed to the component on the other side of the wall W or the floor F. In the example shown in FIGS. 3 and 4, the flange body 6 has substantially the same structure as the outer casing structure 3e, and has a short cylindrical body 6a and an annular plate portion 6b. In the example shown in FIG. 4, the sleeve body 3 is inserted into the through hole Ha formed in the base material 1 constituting the floor F from the other end 3 b of the sleeve until the outer shell 3 c is caught by the base material 1. After fixing the outer casing 3 c to the base material 1, two fireproof coating materials 2 and 2 are stuck on the base material 1, and one fireproof coating material 2 (on the lower floor) The position where the annular plate portion 6b is caught by the fire-resistant covering material 2 while passing the tube other end 3b side of the sleeve body 3 inside the short cylindrical body 6a of the flange body 6 from the state where the ceiling is attached) The short cylindrical body 6a is inserted into the through hole Ha formed in the fireproof covering material 2 until the annular plate portion 6a is fixed to the fireproof covering material 2. And after this, the fireproof coating material 2 is further stuck under the fireproof coating material 2. In this case, the sleeve body 3 can be supported by the constituent material on the cylinder one end 3a side and the cylinder other end 3b side, and the cylinder body other end 3b side of the sleeve body 3 is supported by the flange body 6. The filling bottom of the outer incombustible material 5 can also be formed.

  FIG. 5 shows an example in which a fireproof structure is applied to the through-hole H of a wall W (a general wall W, typically a wall W partitioning a room of a detached house) that becomes a fireproof structure. In this example, the outer shell 3c is caught in the through hole Ha formed in the base material 1 on the one surface side of the wall W, and the base material 1 on the other surface side of the wall W is formed. After the sleeve body 3 is inserted from the other end 3b of the sleeve 3 to the position where the other end 3b of the sleeve body 3 enters the through hole Ha, the outer casing 3c is fixed to the base material 1 on the one surface side of the wall W. Two fireproof coatings 2 and 2 are attached to the outside of the base material 1 on one side of W, and two fireproof coatings 2 and 2 are placed on the outside of the base material 1 on the other side of the wall W. I am trying to stick. Also in this example, the sleeve body 3 has the cylinder one end 3a and the other cylinder end 3b positioned outside the outer surface of the wall W serving as a fireproof structure. Thereby, the flame that propagates along the outer surface of the wall W is prevented from being guided in the penetrating portion H in the direction of entering the wall W. In FIG. 5, the code | symbol 7 has shown the sound insulation material. In this case, it is preferable that the total length of the sleeve body 3 is 200 mm to 350 mm, the distance from the cylinder end 3a to the outer casing 3c is 45 mm to 120 mm, and the distance from the outer casing 3c to the other end 3b is 155 mm to 230 mm. . In this manner, when the fireproof structure according to the embodiment is applied to the through-hole H of the general wall W, the wall W that forms the fireproof structure at the one end 3a and the other end 3b of the sleeve body 3 respectively. It can be made to protrude in the range of 15-20 mm from the outer surface.

  FIG. 6 shows an example in which a fireproof structure is applied to the through-hole H of a wall W (a boundary wall W, typically a wall W that partitions an apartment house) that becomes a fireproof structure. In this example, the outer shell 3c is caught in the through hole Ha formed in the base material 1 on the one surface side of the wall W, and the base material 1 on the other surface side of the wall W is formed. After the sleeve body 3 is inserted from the other end 3b of the sleeve 3 to the position where the other end 3b of the sleeve body 3 enters the through hole Ha, the outer casing 3c is fixed to the base material 1 on the one surface side of the wall W. Two fireproof coatings 2 and 2 are attached to the outside of the base material 1 on one side of W, and two fireproof coatings 2 and 2 are placed on the outside of the base material 1 on the other side of the wall W. I am trying to stick. Also in this example, the sleeve body 3 has the cylinder one end 3a and the other cylinder end 3b positioned outside the outer surface of the wall W serving as a fireproof structure. Thereby, the flame that propagates along the outer surface of the wall W is prevented from being guided in the penetrating portion H in the direction of entering the wall W. In FIG. 6, the code | symbol 7 has shown the sound insulation material. In this case, it is preferable that the total length of the sleeve body 3 is 280 mm to 430 mm, the distance from the tube end 3a to the outer casing 3c is 60 mm to 135 mm, and the distance from the outer casing 3c to the other end 3b is 220 mm to 295 mm. .

In this example, the outer casing 3c is caught in the through hole Ha formed in the base material 1 on the outdoor side of the building on the wall W, and the base material on the indoor side of the building on the wall W. After the sleeve body 3 is inserted from the other end 3b of the sleeve body 3 to the position where the other end 3b of the sleeve body 3 enters the through hole Ha formed in 1, the outer casing 3c is fixed to the base material 1 on the outdoor side. Three fireproof coverings 2 ... 2 (calcium silicate plate) are put on the outside of the base material 1 on the outdoor side, and two fireproof covering materials 2 are placed on the outside of the base material 1 on the indoor side. 2 (gypsum board). Also in this example, the sleeve body 3 has the cylinder one end 3a and the other cylinder end 3b positioned outside the outer surface of the wall W serving as a fireproof structure.
