Description

  The present invention relates to a construction structure of a soundproof tube that is inserted and supported through a through-hole provided in a partition portion such as a wall, floor, or partition of a building.

  Usually, for example, when pipes such as water supply / drainage pipes and refrigerant pipes are supported in a state of penetrating partitions such as walls and floors in a building, in the unlikely event of a fire, There is a possibility that the fire spreads from the surrounding area. Therefore, various fire prevention treatments are performed to prevent such a fire from spreading. As this type of fire prevention treatment, for example, in a state where the tube body is inserted through the through hole provided in the partition portion, the outer peripheral surface (outermost layer) of the tube body and the inner peripheral surface of the through hole of the partition portion There is known a method in which a gap such as mortar is filled in the gaps (see, for example, Patent Document 1). Incidentally, the pipe body shown in this patent document 1 includes a pipe, a sheath pipe covering the outer periphery of the pipe, and a sound-absorbing material (thermally expandable having sound-absorbing properties) disposed between the pipe and the sheath pipe. Material) and functions as a soundproof tube.

According to the fireproofing process shown in Patent Document 1, the gap between the outer peripheral surface of the soundproofing tube and the inner peripheral surface of the through hole is filled with a filler such as mortar and closed, and the soundproofing tube is fixed. Will come to be. As a result, even if a fire breaks out, it is possible to prevent the heat, smoke, flame, etc. generated in one space bounded by the partition from moving to the other space, thus preventing the expansion of the fire.

  By the way, when the outermost layer (sheath tube in Patent Document 1) is formed of a polymer material such as synthetic resin or rubber, the following problems may occur. That is, due to poor compatibility between the polymer material and the mortar (filler), the adhesiveness of the mortar after construction may be lowered. Thereby, the support state of the soundproofing tube becomes unstable, and the soundproofing tube becomes easy to rattle. In the unlikely event that the soundproof tube is rattling, the mortar may be peeled off, and a gap may be formed between the outermost layer of the soundproof tube and the inner peripheral surface of the through hole. The generation of this gap allows movement of heat, smoke, flames, etc. from one space to the other space with the partition of the building as a boundary.

  This invention is made | formed in view of such the conventional situation, The objective is to provide the construction structure of the soundproof tube which can improve the adhesiveness of the mortar with respect to a soundproof tube suitably.

In order to achieve the above object, the construction structure of the soundproof tube of the invention according to claim 1 includes a tube, a sound insulation layer covering the tube, an outer peripheral surface of the tube, and the sound insulation layer. A soundproof tube, which is provided in a gap with the inner peripheral surface and is formed by a sound absorbing layer made of a porous material and is supported by penetrating through a mortar in a penetrating portion provided in a partition of a building. In the construction structure of the body, the soundproofing tube further includes a coating film made of a heat-shrinkable film on the outer peripheral surface of the soundproofing layer, and at least on the facing surface of the soundproofing tube facing the through portion An adhesive member is attached to a part of the adhesive member, and the adhesive member is formed of an adhesive layer attached to the soundproof tubular body and a base fabric layer laminated on the adhesive layer. It becomes the summary.

According to this configuration, the mortar enters between the outer surfaces of the sticking member, that is, the fibers forming the base fabric layer, and the mortar is in close contact with each fiber. As a result, even when the outermost layer of the soundproof tube is made of a polymer material such as synthetic resin or rubber, the mortar and the soundproof tube are bonded via the base fabric layer and the adhesive layer. Sexuality is enhanced. As a result, the sound proof tube is supported by the mortar in a favorable state, and rattling of the sound proof tube is suppressed as much as possible. Eventually, the generation of a gap between the penetrating portion of the partitioning portion and the outer peripheral surface of the soundproofing tube due to the mortar being peeled off as the soundproofing tube is rattling is suppressed. In the event of a fire, heat, smoke, flame, etc. generated in one space with the partition as a boundary are reliably suppressed from moving to the other space. In addition, the covering film suppresses the peeling of the tape material fixing the sound insulating layer to the tubular body, and can protect the sound insulating layer and thus the sound absorbing layer. Even in this case, the adhesion between the mortar and the soundproof tube is ensured through the base fabric layer and the adhesive layer.

  The construction structure of the soundproof tube of the invention according to claim 2 is the invention according to claim 1, wherein the adhesive layer and the base fabric layer are opposed surfaces of the soundproof tube facing the penetrating portion. The gist is that it is disposed over the entire surface.

  According to this configuration, the adhesive layer and the base fabric layer are provided over the entire surface of the opposing surface of the soundproof tube. That is, the sticking property of the sticking member to the soundproofing tube is improved, and the adhesiveness between the mortar and the soundproofing tube is enhanced in the circumferential direction of the soundproofing tube. As a result, the support state of the soundproof tube is very good.

The construction structure of the soundproof tube of the invention according to claim 3 is the gist of the invention according to claim 1 or claim 2, wherein the surface density of the base fabric layer is 5 to 300 g / m ^2. To do.
According to this configuration, an appropriate amount of mortar that can suitably improve the adhesiveness to the soundproof tube enters between the fibers forming the base fabric layer.

  According to the construction structure of the soundproof tube of the present invention, the adhesiveness of the mortar to the soundproof tube can be suitably increased.

Hereinafter, an embodiment in which a construction structure of a soundproof tube according to the present invention is embodied will be described with reference to the drawings.
As shown in FIG. 1, the soundproof tube 11 of this embodiment is supported in a state of being inserted through a through hole 21 (through portion) formed in a partition portion 20 such as a wall, floor, or partition of a building. Yes. In this soundproof tube 11, a sticking member 30 is stuck to a facing surface 11 a that faces a through hole 21 (specifically, an inner peripheral surface that forms the through hole 21). The sticking member 30 is stuck on the entire surface of the facing surface 11a. The mortar 25 is filled in the gap between the outer surface of the sticking member 30 and the inner peripheral surface of the through hole 21. As a result, even if a fire breaks out, the heat, smoke, flame, etc. generated in one space with the partition 20 as a boundary is suppressed from moving to the other space, thus suppressing the expansion of the fire can do.

Hereinafter, the soundproof tube 11 and the sticking member 30 will be sequentially described.
As shown in FIG. 2, the soundproof tube 11 in the present embodiment includes a tube 12 that is a main body of the soundproof tube 11, a sound insulation layer 13 that covers the periphery of the tube 12, and outer peripheries of these tubes 12. The sound absorbing layer 14 is provided in the gap between the surface and the inner peripheral surface of the sound insulating layer 13. The soundproof tube 11 constitutes a pipe by being arranged in a building, and such a pipe is connected to a water supply / drainage device or an air conditioner provided in the building. The soundproofing tube 11 has a sound absorbing function for absorbing the sound based on the fluid flow through the tube 12 by the sound absorbing layer 14, and the sound based on the fluid flow propagates to the outside of the soundproofing tube 11. The sound insulation layer 13 has a sound insulation function to suppress this.

  The tube body 12 is formed of various hard materials and soft materials, and has a cylindrical shape in which a fluid flows. The material for forming the tube body 12 is not particularly limited, and examples thereof include synthetic resins such as polyvinyl chloride and polyethylene, and metals. These materials are used alone or in combination. That is, the tubular body 12 may be either hard or soft. Furthermore, the tubular body 12 may be configured to be partially bent by configuring a part of the tubular body 12 from a hard material and configuring the other part of the tubular body 12 from a soft material.

  The sound absorbing layer 14 exhibits a function of attenuating vibration energy such as sound incident on the sound absorbing layer 14. The sound absorbing material forming the sound absorbing layer 14 is not particularly limited, and specific examples thereof include porous materials such as glass wool, rock wool, ceramic wool, and foamed resin material.

  The sound insulating layer 13 exhibits a function of insulating sound transmitted through the sound absorbing layer 14. The sound insulation layer 13 is made of a material having a high specific gravity and a high surface density. Therefore, even if sound propagates to the sound insulation layer 13, the vibration of the sound insulation layer 13 itself is suppressed. That is, the sound insulating layer 13 has a sound insulating effect for suppressing sound from leaking from the outer peripheral surface thereof. The sound insulation layer 13 of the present embodiment is fixed to the tubular body 12 with a tape material (not shown).

  Specific examples of the sound insulating material for forming the sound insulating layer 13 include metal thin films and polymer materials (synthetic resins, rubbers, etc.). Synthetic resins include vinyl chloride resins, elastomers such as polyolefin elastomers, and rubbers include acrylonitrile-butadiene rubber (NBR), styrene-butadiene rubber (SBR), butyl rubber (IIR), and the like. In addition, when applying a polymer material as the sound insulation material, it is preferable to fill the polymer material with a filler from the viewpoint of improving the sound insulation performance, and from the viewpoint of imparting fire resistance, blending thermally expandable graphite It is preferable to do. Examples of this type of filler include barium sulfate, calcium carbonate, talc, magnesium oxide, alumina, titanium oxide, barite, iron powder, zinc oxide, and graphite.

  In addition, the soundproof tube 11 of the present embodiment includes a covering film 17 that covers the entire periphery of the sound insulating layer 13. That is, in the soundproof tube 11, the outermost layer is formed by the covering film 17. The covering film 17 serves to hold the sound insulating layer 13 on the tubular body 12 and to protect the sound insulating layer 13 and the sound absorbing layer 14. The covering film 17 of this embodiment is comprised from the heat-shrinkable film. The heat-shrinkable film is also called a shrink film, and a film made of a synthetic resin such as polypropylene, polyethylene, or polyester is used.

  As shown in FIG. 3, the adhering member 30 in the present embodiment includes an adhering layer 31 that is adhering to the facing surface 11 a (outer peripheral surface) of the soundproofing tube 11, and a base that is laminated on the adhering layer 31. The cloth layer 33 is formed. Hereinafter, the adhesive layer 31 and the base fabric layer 33 constituting the adhesive member 30 will be sequentially described.

  As shown in FIG. 4, the adhesive layer 31 is provided over the entire surface of the opposing surface 11 a of the soundproof tube 11. That is, the adhesive layer 31 is provided over the circumferential direction on the facing surface 11 a of the soundproof tube 11. The material for forming the adhesive layer 31 is not particularly limited as long as it has adhesiveness. Specific examples of this type of material include, for example, butyl rubber (IIR), isoprene rubber (IR), natural rubber (NR), butadiene rubber (BR), 1,2-polybutadiene rubber (1,2-BR), and styrene. -Butadiene rubber (SBR), chloroprene rubber (CR), nitrile rubber (NBR), ethylene-propylene rubber (EPM, EPDM), chlorosulfonated polyethylene (CSM), acrylic rubber (ACM, ANM), epichlorohydrin rubber (CO, ECO), polyvulcanized rubber (U), silicone rubber (O), fluoro rubber (FKM, FZ), urethane rubber (U), polyisobutylene rubber, butyl chloride rubber, etc., polyvinyl acetate, ethylene-vinyl acetate Vinyl acetate resins such as copolymers, acrylic resins, urethane resins, silicone resins Hydrocarbon resins, alkylphenol resins, other acrylonitrile, rosin, rosin triglycerides, include rosin resins such as hydrogenated rosin. These may be used independently and 2 or more types may be used together. Among these, in this embodiment, butyl rubber (IIR) or isoprene rubber (IR), which is inexpensive and excellent in adhesiveness, is preferable, and hydrogenated one is particularly preferable. Further, in this case, from the viewpoint of enhancing the sticking property of the sticking member 30 to the soundproof tube 11, a liquid resin such as polybutene or a petroleum resin as a tackifier is blended with butyl rubber (IIR) or isoprene rubber (IR). May be.

  The thickness of the sticking layer 31 is 0.3-2 mm, Preferably it is 0.5-1.5 mm. When the thickness of the sticking layer 31 is less than 0.3 mm, there is a possibility that the sticking property of the sticking member 30 to the soundproof tube 11 cannot be sufficiently secured. On the other hand, when the thickness of the sticking layer 31 exceeds 2 mm, the thickness of the sticking member 30 as a whole becomes excessive, and the weight of the sticking member 30 increases. Thereby, the handleability of the sticking member 30 may fall.

  As shown in FIGS. 3 and 4, the base fabric layer 33 is laminated over the entire surface of one surface (outer surface 31 a) of the adhesive layer 31. That is, the base fabric layer 33 is also provided over the entire surface of the opposing surface 11 a of the soundproof tube 11, as with the adhesive layer 31. The base fabric layer 33 of this embodiment is formed from a nonwoven fabric. The fiber forming this nonwoven fabric may be either a long fiber or a short fiber. This type of fiber is not particularly limited, and specific examples thereof include, for example, a flame-resistant fire such as polyester fiber, polypropylene fiber, polyethylene fiber, polyamide fiber, acrylic fiber, aromatic polyamide fiber, glass wool, rock wool and the like. Known fibers such as fibers are used. Among these, in the present embodiment, polypropylene fibers and polyethylene fibers are preferable in addition to polyester fibers such as polyethylene terephthalate, polybutylene terephthalate, and polytrimethylene terephthalate, from the viewpoints of handleability and price.

The surface density of the base fabric layer 33 is 5 to 300 g / m ² , and preferably 10 to 100 g / m ² . When the surface density of the base fabric layer 33 is less than 5 g / m ² , the gap area between the fibers forming the base fabric layer 33 becomes extremely large, so that the shape retainability may be lowered. For this reason, there is a high possibility that uniform adhesion between the mortar 25 and the soundproof tube 11 cannot be obtained. On the other hand, when the surface density of the base fabric layer 33 exceeds 300 g / m ² , no further effect is observed with respect to the adhesiveness between the mortar 25 and the soundproofing tube 11, which is not economical.

The base fabric layer 33 is laminated on the adhesive layer 31 due to the adhesiveness of the adhesive layer 31. In this case, the base fabric layer 33 may be further laminated on the adhesive layer 31 using an adhesive.
Next, the construction method of the soundproof tube 11 of this embodiment will be described.

  When constructing the soundproofing tube 11, first, the soundproofing tube 11 is inserted into the through hole 21 of the partition part 20, and in this state, the bonding member 30 is bonded to the facing surface 11 a of the soundproofing tube 11. (See FIG. 5). At this time, it is preferable that the sticking member 30 is wound around the entire surface of the facing surface 11a of the soundproof tube 11 at least once. And the clearance gap between the outer surface (base fabric layer 33) of the said adhesion member 30 and the internal peripheral surface of the said through-hole 21 in the state in which the adhesion member 30 was adhered to the opposing surface 11a of the soundproof tube 11 Is filled with mortar 25.

  At this time, the mortar 25 enters the outer surface of the sticking member 30, that is, the inside of the base fabric layer 33. More specifically, the mortar 25 enters between the fibers forming the base fabric layer 33. The mortar 25 is cured while being in close contact with each fiber forming the base fabric layer 33. Thereby, the mortar 25 is firmly bonded to the base fabric layer 33. As a result, the soundproofing tube body 11 is firmly bonded to the outer surface of the soundproofing tube body 11 through a bonding member 30 bonded to the soundproofing tube body 11. As a result, the sound proof tube 11 is supported by the mortar 25 in a favorable state, and rattling is suppressed as much as possible.

  Therefore, according to the present embodiment, the gap between the outer peripheral surface of the soundproof tube 11 and the inner peripheral surface of the through hole 21 due to the mortar 25 being peeled off as the soundproof tube 11 is rattling. Generation | occurrence | production is suppressed suitably. Therefore, even in the event of a fire, the movement of heat, smoke, flame, etc. generated in one space with the partition 20 as a boundary is reliably suppressed from moving to the other space.

The adhesiveness of 25 can be suitably increased.

  (2) The base fabric layer 33 and the adhesive layer 31 constituting the adhesive member 30 are provided over the entire facing surface 11 a of the soundproof tube 11. Therefore, the adhesiveness of the mortar 25 with respect to the soundproofing tube body 11 can be improved over the circumferential direction of the soundproofing tube body 11 by such a base fabric layer 33. Furthermore, the sticking property of the base fabric layer 33 to the soundproof tube 11 can be sufficiently secured via the sticking layer 31.

(3) The surface density of the base fabric layer 33 is 10 to 70 g / m ² . For this reason, when the mortar 25 is filled in a predetermined place, an appropriate amount of the mortar 25 that can suitably improve the adhesion to the soundproof tube 11 is inserted between the fibers forming the base fabric layer 33. Can do.

  (4) A coating film 17 that covers the sound insulation layer 13 is provided on the outer peripheral surface of the soundproof tube 11. Therefore, peeling of the tape material fixing the sound insulating layer 13 to the tubular body 12 can be suppressed by such a covering film 17. In addition, it is possible to protect the sound insulating layer 13 and thus the sound absorbing layer 14.
