Description

  The present invention relates to a ventilation plate for a building that is installed on a building ridge or wall such as a gable roof and is suitable for ventilation in a hut or room, and is particularly provided in the wall of a building. It is possible to ventilate the inside and outside of the building such as the back of the building through the ventilation layer, and prevent foreign matter such as rain, snow, dust, insects and birds from entering the room from the outside. The present invention relates to a building ventilation plate that can be prevented.

  Conventionally, in a building such as a general house, a heat insulating material such as polystyrene foam, polyurethane foam, or glass fiber is arranged between the outer wall and the inner wall to improve the heat insulating property between the outside and the room, and heating efficiency and cooling Often configured to increase efficiency. Therefore, in the buildings such as the above general houses, the air permeability between the room and the outside is lowered, the indoor humidity is likely to be high, and there is a possibility that condensation or wrinkles may occur on the wall surface of the room. .

  Therefore, in recent buildings, especially in cold districts where heating appliances are used for a long period of time, using natural convection of the air, the indoor humid air is exhausted to the outside and ventilated. A ventilation layer is provided on the outside, vents are arranged at the junction between the roof and the outer wall, and air and moisture in the building are passed through the vents provided at the roof ridge and the junction between the roof and the outer wall. In many cases, an attic ventilation device configured to exhaust the air to the outside is provided.

  By the way, as a technique regarding this type of roof ventilation apparatus, for example, there is one disclosed in Japanese Patent No. 2610342. The ridge cover member according to this Japanese Patent No. 2610342 is composed of two plate-like ridge ventilation members attached to the roof ridge from the room to the outside, and is configured so that the cross-sectional shape exhibits a substantially inverted V shape, Each building ventilation member is formed from a material such as plastic so that each building ventilation member is tapered from the upper surface to the lower surface, and each building ventilation member is provided with a large number of communicating vents from one side to the other. is there.

  The ridge cover member according to the above-mentioned Japanese Patent No. 2610342 has a negative pressure on the lower surface of the ridge ventilation member due to the airflow flowing downward from the ridge portion along the surface of the roof, and from the vent on the upper surface of the ridge ventilation member. It sucks indoor air and exhausts it outside the room, and functions as an eaves ventilation member.

Japanese Patent No. 2610342

  However, the conventional technique has the following problems. That is, in the case of the ridge cover member according to the above-mentioned Japanese Patent No. 2610342, it consists of two plate-like ridge ventilation members, and each ridge ventilation member is provided with a large number of communicating vents from one side to the other side. Since the thickness is fixed, the moisture permeable waterproof sheet is stretched on the surface of a heat insulating material such as glass wool. When arranging this in the ventilation hole by the gap between the heat insulating material stretched on the surface and the outer wall material, the thickness of the waterproof ventilation plate and the gap between the heat insulating material and the outer wall material differ even in part, A gap is generated between the two, and the intended purpose of preventing entry of dust, insects and the like cannot be achieved.

  In order to prevent such problems, it is conceivable to prepare a plurality of types of members having different thicknesses and use ones suitable for the gap between the heat insulating material and the outer wall material. Since it is necessary to manufacture and stock a plurality of types of different members, the manufacturing cost increases.

  Furthermore, in order to prevent the above problems, it may be possible to adjust the dimensional error between the heat insulating material and the outer wall material by attaching another plate material to the ridge cover member. However, there was another problem that the work man-hours greatly increased.

  Accordingly, the present invention has been made to solve the above-described problems of the prior art, and the object of the present invention is to provide good indoor ventilation and to prevent rain, snow, and dust from the outside. In addition, it is possible to surely prevent foreign matter such as insects from entering the room, as well as dimensional errors present in the vents provided in the roof ridge part and the joint between the roof and the outer wall, etc. It is an object of the present invention to provide a building ventilation plate capable of easily performing attachment work and effectively preventing intrusion of dust, insects, and the like by effectively absorbing.

  The present invention relates to a ventilation plate for a building that is attached to a part of a building and ventilates from the inside of the building to the outside of the building, a flat board attached to a predetermined location of the building, and the board A ventilation plate for buildings comprising a three-dimensional fine fiber filter fixed on the surface and having an adjustable thickness.

  As the three-dimensional fine fiber filter, for example, a non-woven fabric filter is used. The thickness of the three-dimensional fine fiber filter is adjusted by the three-dimensional fine fiber filter coming into contact with another member.

  According to the present invention, it is possible to satisfactorily ventilate the room and reliably prevent foreign matter such as rain, snow, dust or insects from entering the room from the outside. In addition, it is possible to effectively absorb dimensional errors existing in the vents provided in the roof ridge part and the joint between the roof and the outer wall, and to perform the installation work easily, and to prevent dust and insects. Thus, it is possible to provide a building ventilation plate capable of effectively preventing the intrusion of the like.

  Embodiments of the present invention will be described below with reference to the drawings.

  In FIG. 2, reference numeral 1 denotes a general house as a building, and this house 1 is roughly divided and configured with a roof 4 placed on top of a room 3 surrounded by a side wall 2. A space 6 between the ceiling 5 and the roof 4 of the room 3 is provided. As shown in FIGS. 2 to 4, the wall surface 2 is formed by laying horizontal rails 9 for mounting on a concrete foundation 7 through two airtight packing materials 8, and four corners on the horizontal rails 9. The column material 10 is erected on the other side, and the pillar 11 is erected between the column materials 10. Further, as shown in FIG. 5, a heat insulating material 12 such as glass wool is disposed between the column material 10 and the inter-column 11 and the inter-columns 11 so as to improve the heat insulation between the outdoor 13 and the indoor 6. It has become. A moistureproof / airtight sheet 14 is stretched on the indoor surface of the heat insulating material 12 such as glass wool, and then a wall surface material 15 such as a gypsum board is attached to the surface of the moistureproof / airtight sheet 14. In FIG. 5, the code | symbol 16 has shown the flooring.

 In addition, as shown in FIG.6 and FIG.7, you may comprise so that the airtight packing material 8 may not be interposed between the concrete foundation 7 and the crosspiece 9. FIG.

  Further, as shown in FIG. 5, a moisture permeable / waterproof sheet 17 is stretched on the outdoor surface of the heat insulating material 12 such as glass wool, and then an outer wall material 21 is attached to the lower surface of the wall surface 2. A building ventilation plate 20 according to the present embodiment is attached to the opening 18 of a predetermined gap (for example, 18 mm) to be formed. Further, as shown in FIGS. 8 and 9, the surface of the moisture permeable / waterproof sheet 17 is fixed by a vertical trunk edge 19 arranged along the vertical direction.

  Further, on the lower part of the wall surface 2, a flat drainage 22 bent into a predetermined shape is provided on the outer side or the inner side of the moisture permeable / waterproof sheet 17. It is arranged so as to cover from the outside to the position reaching the upper end of the concrete foundation.

  By the way, the building ventilation plate according to the present embodiment is a ventilation plate for a building that is attached to a part of the building and ventilates from the inside of the building to the outside of the building. A flat substrate to be attached and a three-dimensional fine fiber filter fixed on the surface of the substrate and having an adjustable thickness are provided.

  In addition, as the three-dimensional fine fiber filter, for example, a non-woven fabric filter is used.

  That is, the building ventilation plate 20 according to the present embodiment includes a flat board 25 attached to a predetermined location of the building as shown in FIG. The substrate 25 is formed of, for example, a synthetic resin such as polypropylene (PP) or acrylic in a cardboard shape by injection molding or the like so that it does not rot even after long-term use. If fire resistance or other performance is required, even if the substrate 25 is formed of ceramic, aluminum, steel, or the like, the substrate 25 is not formed by injection molding or the like, but is formed at a construction site or the like. Also good.

  As the substrate 25, for example, a plate-like member (trade name “Purapearl” or the like) having a thickness of about 3 mm, which is called an intake / exhaust galley disclosed in Japanese Patent No. 2676319, is used.

  The substrate 25 of the building ventilation plate 20 of the present invention is for solving the difficulty in handling, quantity confirmation or packaging of the three-dimensional fine fiber filter 26 described below, In order to facilitate the cutting, for example, the thickness is 3 mm, the width is 35 mm, and the length is 1820 mm.

  A three-dimensional fine fiber filter 26 having a thickness of 20 mm is fixed to the surface of the substrate 25 by means such as adhesion. The three-dimensional fine fiber filter 26 may be provided over the entire width of the substrate surface. However, in the illustrated embodiment, the three-dimensional fine fiber filter 26 is provided over a width of 20 mm on one end (lower end) side in the width direction of the substrate. The three-dimensional fine fiber filter 26 is not provided on the substrate surface. The portion of the surface of the substrate 25 exposed without providing the three-dimensional fine fiber filter 26 is used for driving nails when the building ventilation plate 20 is attached. Note that the three-dimensional fine fiber filter 26 may be configured to be provided over the entire width of the substrate 25.

As the three-dimensional fine fiber filter 26, for example, a three-dimensional fine fiber filter made of nonwoven fabric is used, but is not limited thereto. As the three-dimensional fine fiber filter 26, for example, melted synthetic resin is threaded into water from a thin nozzle, so that parts of the synthetic resin thread-like members are bonded to each other to form a three-dimensional nonwoven fabric. For example, Saran Lock (registered trademark) manufactured by Asahi Kasei Co., Ltd. can be used. The three-dimensional fine fiber filter 26 has a porosity of about 95% and a specific surface area of 600 to 740 m ² / m ³ , but the thickness (denier) and bulk density of the thread-like member made of synthetic resin. Alternatively, various products can be manufactured by changing the space ratio, and those having desired characteristics are appropriately selected and used. If fire resistance or other performance is required, the three-dimensional fine fiber filter 26 may be formed of ceramic, aluminum, steel, or the like.

  In the above configuration, the building ventilation plate 20 according to the present embodiment can satisfactorily ventilate the room as follows, and it is possible to prevent rain, snow, dust, insects, etc. from the outside. Of course, it is possible to reliably prevent foreign matter from entering the room, and even if there is a dimensional error in the vent due to the gap between the heat insulating material and the outer wall material, the dimensional error can be reduced. It can absorb effectively, can perform attachment work easily, and can prevent invasion of dust, an insect, etc. effectively.

  That is, the building ventilation plate 20 according to this embodiment is attached to the lower part of the wall surface 2 filled with the heat insulating material 12 and the moisture permeable / waterproof sheet 17 stretched over the entire surface, as shown in FIG. It is done. As shown in FIGS. 3 and 4, the ventilation plate 20 for a building is configured such that a portion of the substrate 25 where the three-dimensional fine fiber filter 26 is not provided is combined with a moisture permeable / waterproof sheet 17 by a nail 30 or the like and a crosspiece 9. The opening 18 provided in the lower part of the wall surface 2 is disposed so as to be closed. In that case, the said ventilation plate 20 for buildings is arrange | positioned so that the board | substrate 25 may be located in the crosspiece 9 side, and the three-dimensional fine fiber filter 26 may be located in the outer wall material 21 side.

  And as shown in FIG.8 and FIG.9, the outer wall material 21 is laid in the outdoor side of the said wall surface 2 through the moisture-permeable / waterproof sheet 17 and a predetermined gap, and the wall surface 2 is completed. At that time, the opening 18 has a variation in the gap between the moisture permeable / waterproof sheet 17 and the outer wall material 21 because the three-dimensional fine fiber filter 26 of the building ventilation plate 20 is pressed by the outer wall material 21. However, since the three-dimensional fine fiber filter 26 is elastically deformed and absorbed, the gap variation surely prevents the gap from being generated between the moisture permeable / waterproof sheet 17 and the outer wall material 21. Is possible.

  The three-dimensional fine fiber filter 26 has air permeability and can reliably prevent foreign matter such as rain, snow, dust, or insects from entering the room 13 from the outside.

  Thus, in the building ventilation plate 20 according to the above embodiment, the room 6 can be well ventilated, and foreign matter such as rain, snow, dust, or insects can enter the room from the outside 13. Of course, it is possible to reliably prevent dimensional errors caused by drying and the skill of the installer, which are present in the gap between the heat insulating material 12 and the outer wall material 21. Thus, the attachment work can be easily performed, and the entry of dust, insects, and the like can be effectively prevented.

  In the said Embodiment 1, although the ventilation plate 20 for buildings of this invention was arrange | positioned in the clearance gap between the heat insulating material 12 and the outer wall material 21, the application site | part of the ventilation plate for buildings of this invention is restricted to this. If it is a part that is required to ventilate the room, such as a ventilation plate for eaves, and to prevent foreign matter such as rain, snow, dust, or insects from entering the room from the outside, Can be applied without any changes.

  That is, as shown by 20 'in FIG. 2, the building ventilation plate of the present invention can be used not only for eaves ventilation but also for ridges and eaves ventilation in so-called snow-free roofs. .
