As a result, in the above-mentioned buildings such as ordinary houses, the air permeability between the room and the outside is reduced, and the humidity in the room is likely to increase, and there is a possibility that dew condensation and mold may occur on the wall surfaces of the room. Was. ·

Therefore, in recent years, especially in cold places where heating equipment is used for a long period of time, insulation has been used in recent years to use the natural convection of air to exhaust indoor humid air and ventilate it. A ventilation layer is provided on the outside of the timber, and a vent is provided at the joint between the roof and the outer wall. A roof ventilation system configured to exhaust moisture to the outside is provided Often.

The three-dimensional fine fiber filter is filled so as to shield one end and the other end of the hollow base.

That is, as shown in FIG. 4, the hollow base 23 constituting the hollow waterproof ventilation plate 17 for a building is a pair of flat upper plates 19 arranged to face each other with a predetermined gap therebetween, as shown in FIG. It is a horizontally long and rectangular cross section composed of the lower plate 20 and the left and right side plates 21. In this embodiment, the upper plate 19 and the lower plate 20 are provided to prevent the hollow base 23 from bending. An appropriate number of ribs 22 are formed between them. For buildings above As shown in FIG. 5, the hollow substrate 23 constituting the hollow waterproof ventilation plate 17 is made of a pair of flat upper and lower plates 19 and 20 made of, for example, a synthetic resin such as polypropylene (PP) or acrylic. The left and right side plates 21 and the ribs 22 are integrally formed by injection molding or the like. If fire resistance or other performance is required, even if the hollow substrate 23 is made of ceramic, aluminum, steel, etc., it will not be integrally formed by injection molding, etc. The hollow substrate 23 may be assembled by such means as shown in FIG. 1. Also, as shown in FIG. 1, the side surface is formed in a trapezoidal shape (for example, in a state in which it is inclined from the vertical direction to the inside, for example, 30 degrees). Is also good. The hollow base material 23 of the hollow waterproof ventilation plate 17 for buildings according to the present invention has, for example, a distance between the upper plate 19 and the lower plate 20 of 15 mm and a distance between the ribs 22 of 15 to 15 mm.

Alternatively, a portion between one end and the other end may be filled. Further, the three-dimensional fine fiber filter 1 may be simply filled in the hollow base 23, or may be welded or bonded inside the hollow base 23. Further, for example, when the hollow base 23 has the rib 22, as shown in FIG. 6, the upper plate 19, the side wall 21, and the rib 22 of the hollow base 23 have a predetermined width W ( For example, a notch 24 cut out by 15 mm) may be provided along a direction orthogonal to the direction of communication of the hollow base 23, and the notch 24 may be filled with the three-dimensional fine fiber filter 25. . When the hollow base 23 is formed of a synthetic resin such as polypropylene, the cutout portion 25 may of course be configured such that the upper plate 19 and the ribs 22 are not provided in advance.

In addition, the three-dimensional fine fiber filter 25 is formed by cutting a part of the hollow base 23, which is slightly wider than the width W of the cutout 24, into the cutout 24 by press-fitting. Due to the elasticity of the one-dimensional fine fiber filter 25, it can be filled in a fixed state in the notch 24, and if necessary, may be welded or bonded in the notch 24.

Further, as shown in FIG. 7, a notch 2 filled with a three-dimensional fine fiber filter 25 is formed in an upper plate 19 of the hollow base plate 23 of the hollow waterproof ventilation plate 17 for a building of the present invention, as shown in FIG. A plate-like member 26 may be provided so as to cover the upper part of the plate 4.

In any case, as the three-dimensional fine fiber filter 25, for example, a molten synthetic resin is drawn through a fine nozzle into water, as shown in FIG. A part of 27 that is adhered to each other and is a cotton-like elastically deformable material of three-dimensional non-woven futon. For example, Saran Lock (registered trademark) manufactured by Asahi Kasei Corporation is used. . The three-dimensional fine fiber filter 2 5, for example, about voidage 95%, but those that are set on the specific surface area ^{6 0 0~ 7 4 0 mVm 3} , the thickness of the synthetic resin thread members 2 7 By changing the (denier), the bulk density, or the porosity, various types can be manufactured, and those having desired characteristics are appropriately selected and used. If fire resistance or other performance is required, a three-dimensional fine fiber filter made of ceramic, aluminum, steel, etc. Luter 25 may be formed.

On the other hand, the hollow waterproof waterproof ventilation plate for a building according to this embodiment is a hollow waterproof waterproof ventilation plate for a building that is attached to a part of the building and performs ventilation from inside the building to outside the building, The hollow waterproof ventilation plate includes a pair of horizontally long hollow base members having a rectangular cross section and a three-dimensional fine fiber filter. The three-dimensional fine fiber filter includes the hollow base member, and an opening of the hollow base member. It may be characterized in that it is disposed so as to abut on the whole.

That is, as shown in FIG. 9 (a), the hollow waterproof ventilation plate 17 for a building of the present invention is formed to be narrower than the hollow substrate 23 similarly to the hollow substrate 23 shown in FIG. (For example, 15 to 20 mm in width) and a pair of hollow bases 28 and 29 each having a trapezoidal side shape of only (28), with a notch formed by appropriately separating them by a distance W. By forming a notch 24 and filling the cutout 24 with a three-dimensional fine fiber filter 25 as shown in FIG. 9 (c), the hollow substrate 28 is filled in the three-dimensional fine fiber filter 25. , 29 may be arranged such that the openings of the hollow bases 28, 29 are entirely in contact with each other.

In the hollow waterproof ventilation plate 17 for a building of the present invention configured as described above, the hollow substrates 28 and 29 are bonded to the three-dimensional fine fiber filter 25 to secure the structure. However, as shown in Fig. 9 (b), plate members 30 and 31 are arranged on the upper and lower parts of the hollow waterproof ventilation plate 17 for building, and the notch 2 4 is closed in the up and down direction, and the cutout 24 thus formed is filled with a three-dimensional fine fiber filter 25 and, if necessary, adhered to the surface with which the three-dimensional fine fiber filter 25 contacts. Is also good.

As described above, when the cutout portion 24 is provided by the pair of hollow bases 28 and 29, the volume of the cutout portion 24, in other words, the amount of the fill member is reduced by the hollow base 28. Can be easily changed by adjusting the distance between the 29. Further, in FIG. 9, the pair of hollow substrates 28 and 29 are arranged so as to form a linear flow path, but the present invention is not limited to this, and the pair of hollow substrates 28 and 2 9 may be arranged so that they form a flow path having a predetermined angle.

In addition, foreign substances such as rain, snow, and dust from outside the building It is possible to reliably prevent the intrusion into the computer.

In other words, in the hollow waterproof ventilation plate 17 for a building according to this embodiment, everything passing from one side to the other side passes through the three-dimensional fine fiber filter 25, Since the three-dimensional fine fiber filter 25 is formed by three-dimensionally entanglement of a synthetic resin or fine fiber metal-based thread member, there is almost no resistance to air passing therethrough. It has an effect of preventing intrusion only to foreign substances such as dust and dust.

In particular, when foreign matter other than air is rain, a water film is formed by retaining the rainwater in the three-dimensional fine fiber filter 25, and thereby it is possible to effectively prevent rainwater from entering.

In addition, since this type of conventional ventilation system for buildings mainly aimed at preventing the intrusion of rainwater by applying the surface tension due to wetting, when foreign matter other than air is snow, almost all In the present invention, the three-dimensional fine fiber filter 25 can surely prevent the invasion of snow.

In addition, foreign substances such as rain, snow, dust, and insects, which are prevented from entering by the three-dimensional fine fiber filter 25, are discharged with time depending on the wind direction outside the building, or rainwater infiltration and washing are repeated or performed. The three-dimensional fine fiber filter 25 is not clogged because it dries or melts when exposed to snow or sunlight or when the temperature rises.

According to the inventor of the present invention, when a hollow waterproof ventilation plate 17 as shown in FIG. 1 was prototyped and tested, it was found that rain and snow could enter even during storms and storms exceeding a wind speed of 4 Om / s. It was verified that it was possible to reliably prevent
