Hereinafter, a ventilation member according to an embodiment of the present invention will be described.
FIG. 1 is a cross-sectional view of a building provided with a keratin ventilation member according to the present embodiment. FIG. 1 (a) is a building with a decorative slate and kerato sheet metal and no decorative gable, and FIG. 1 (b). Figure 1 (c) shows a building with a decorative slate and keraba sheet metal and a makeup gable. FIG. 2 is a diagram showing an example of the shape of the roof of a building. FIG. 2 (a) shows a symmetrical gable roof, FIG. 2 (b) shows an asymmetrical gable roof, and FIG. 2 (c) shows a one-way roof. FIG. 2D shows a flat roof having a slope.
As shown in FIG. 2, the roof of the building 1 has an eave 1B at an end of a plane (flat side) parallel to the ridge 1A and an end 1C at a plane (wife side) perpendicular to the ridge 1A. The building 1 is a so-called eaves-free building with no or small 1C. The ventilation member 20 is installed at the end 1C of the building 1 on the wife side.
As shown in FIG. 1, the building 1 is arranged outside the baseboard 2, a roofing material 3 disposed above the baseboard 2, a wall basement (plywood) 4, and the wall basement 4. An outer wall ventilation member 5, a siding 6 arranged outside the outer wall ventilation member 5, and a connecting member 7 such as a backup material or a one-hat joiner arranged above the siding 6 are provided.
Further, as shown in FIG. 1B, a makeup gable 8 can be provided outside the siding 6. Further, as shown in FIGS. 1A and 1B, a climbing tree (pier) 9 may be provided at the upper part of the eaves side of the baseboard 2. The climbing tree 9 is fastened by a climbing tree fixing nail 10 penetrating the climbing tree 9 and the base plate 2.
The base plate 2 protrudes outside the siding 6 or the decorative gable 8 by a predetermined distance A.
In addition, in the case 1C of the building 1, a case member 11 for protecting the case 1C is installed. The kerb member 11 has, on one side, a hanging portion 11a projecting below the base plate 2 and, on the other hand, an insertion portion 11b inserted between the base plate 2 and the roofing material 3. The lower end of the hanging portion 11a is bent back inward.

In other words, the ventilation member 20 is attached to a position inside the hanging portion 11a and a lower surface (the bottom plate 31 in FIG. 3) above the lower end of the hanging portion 11a. By attaching to this position, the ventilation member 20 is hidden by the member 11 and is barely exposed, so that it becomes difficult for rainwater to blow from the air outlet 36 and contributes to improvement of aesthetic appearance.
When the upper surface (upper plate 34 in FIG. 3) is brought into contact with the base plate 2 from below, the ventilation member 20 is brought into contact with the rear surface (the rear plate 33 in FIG. Then, the rear surface and the outer wall ventilation material 5 are fixed using the fixing tool 60. The fixture 60 is a nail or a screw. In this way, by positioning the ventilation member 20 against the building 1 from two directions, the mounting can be easily and accurately positioned, and the ventilation member 20 can be firmly fixed to the building 1 and the waterproofness can be improved. improves. The connecting member 7 is arranged between the lower surface of the ventilation member 20 and the upper surface of the siding 6.
The dotted arrow B in FIG. 1 indicates the flow of air passing through the inner space on the wife side formed between the wall base material 4 and the siding 6 by the outer wall ventilation material 5. Note that the outer wall ventilation member 5 is a wooden ventilation trunk for forming a space in the wall, a metal member, or the like. In other words, the ventilation member 20 is provided with an air inlet 37 between the rear surface and the upper surface, and an air outlet 36 on the front surface (the front plate 32 in FIG. 3). When the air flows through the air inlet 37, the air flows into the ventilation member 20 and flows out through the air outlet 36. In this manner, the air in the wall space can be exhausted to the outside of the building 1 through the ventilation member 20 without entering the back of the hut, so that the amount of air behind the hut increases, It is possible to prevent the occurrence of wood rot fungi and mold. In addition, since the ventilation member 20 does not communicate with the back of the hut, it is not necessary to make it fireproof.

3A and 3B are views showing the main body, FIG. 3A is a left side view, and FIG. 3B is a front view. Note that the scale of FIG. 3A is larger than that of FIG. 3B for easy viewing.
In other words, the ventilation member 20 includes a main body 30. The main body 30 has a bottom plate 31, a front plate 32, a rear plate 33, an upper plate 34, and a baffle plate 35. Both sides of the main body 30 are open.
The bottom plate 31, the front plate 32, the rear plate 33, the upper plate 34, and the baffle plate 35 are each rectangular and have the same long side length.

The lower end (one long side) of the front plate 32 is connected to the front end (one long side) of the bottom plate 31 and stands upright with respect to the bottom plate 31.
The front plate 32 is provided with an air outlet 36. The air outlet 36 penetrates through the front plate 32, and the air outlet 36 faces in the horizontal direction when the main body 30 is installed on the building 1. Rainwater may be blown up from below by the wind, but since the air outlet 36 is oriented horizontally, the rainwater flows from the air outlet 36 into the main body 30 more than when the air outlet 36 is oriented downward. It becomes difficult to enter.
The air outlet 36 preferably comprises a plurality of circular small holes 36a. The small holes 36a are arranged in a line at predetermined intervals in the longitudinal direction of the front plate 32. By forming the air outlet 36 as a small hole, it becomes difficult for rainwater to enter the main body 30. If the air outlet 36 has a rectangular shape, the rainwater flowing down from above tends to stay on the upper portion of the air outlet 36 due to surface tension. You may get inside. On the other hand, when the air outlet 36 is circular as in the present embodiment, the rainwater flowing down from above does not stay at the upper part of the air outlet 36 but travels down the contour of the air outlet 36 and goes down. Since it flows down, it is difficult for rainwater to enter the main body 30. The circular shape is preferably a perfect circle, but may be a substantially circular shape such as an octagon as shown in FIG.
The air outlet 36 is preferably provided at a position closer to the upper plate 34 than the bottom plate 31 in the front plate 32. Accordingly, since the position of the air outlet 36 is higher than the position of the lower end of the hanging portion 11a of the member 11 installed in the building 1, the blowing of rainwater from the air outlet 36 can be further prevented.

The rear plate 33 is connected to the rear end (the other long side) of the bottom plate 31 and stands upright with respect to the bottom plate 31.
The rear plate 33 has a first rear plate 33a facing the front plate 32, and a second rear plate 33b located farther from the front plate 32 than the first rear plate 33a. The first rear plate 33a prevents rainwater collected from the blow-out bottom plate 31 from the air outlet 36 from entering the space in the wall. The second rear plate 33b serves as a connection portion when fixing the main body 30 to the outer wall ventilation member 5.
The upper end (one long side) of the first rear plate 33a and the upper end (one long side) of the second rear plate 33b are curvedly connected. The upper end of the first rear plate 33a and the upper end of the second rear plate 33b are at the same height, and are lower than the height of the upper end (the other long side) of the front plate 32.
The first rear plate 33a and the second rear plate 33b are apart from each other except for the upper end, and a gap C is formed therebetween.
The lower end (the other long side) of the first rear plate 33a is connected to the rear end of the bottom plate 31, and the lower end (the other long side) of the second rear plate 33b protrudes below the bottom plate 31. A fixing member 60 for coupling the outer wall ventilation member 5 and the second rear plate 33b is driven into a portion of the second rear plate 33b located below the bottom plate 31. By driving the fixing tool 60 into a portion of the second rear plate 33b located below the bottom plate 31, the fixing to the outer wall ventilation member 5 is facilitated. Further, since no hole is formed in the first rear plate 33a by the driving of the fixing tool 60, there is no possibility that rainwater will enter the space in the wall through the hole.

The upper plate 34 has a front end (one long side) connected to an upper end (the other long side) of the front plate 32 and is provided to face the bottom plate 31.
The upper plate 34 is arranged in close contact with the lower surface of the base plate 2 to prevent infiltration of rainwater. It is preferable to provide a waterproof packing 70 on the upper plate 34 so as to cover the entire upper surface thereof. In the case where the waterproof packing 70 is provided on the upper surface of the upper plate 34, it is assumed that a gap is generated between the base plate 2 and the upper plate 34 due to unevenness in construction accuracy, unevenness on the back surface of the base plate 2, and the like. However, since the gap is filled with the waterproof packing 70, it is possible to more reliably prevent rainwater from entering the inside of the main body 30 and the space in the wall. In addition, the wife side where the ventilation member 20 is provided is a place where the risk of infiltration is high, and water stoppage treatment such as caulking is required at the time of construction on a steep slope. Since the water is stopped by the water packing 70, the water stopping process becomes unnecessary.
The length D of the side end (short side) of the upper plate 34 is shorter than the length E of the side end (short side) of the bottom plate 31, and the air inlet 37 is provided between the rear plate 33 and the upper plate 34. Is formed. The air that rises in the space in the wall formed by the outer wall ventilation material 5 flows into the main body 30 from this space (the air inlet 37) and flows out from the air outlet 36.

The baffle plate 35 hangs at a position between the front plate 32 and the rear plate 33. The rainwater blown from the air outlet 36 collides with the baffle plate 35 and drops toward the bottom plate 31. In this way, the baffle plate 35 prevents rainwater blown from the air outlet 36 from entering the outer wall ventilation member 5 through the air inlet 37.
The upper end (one long side) of the baffle plate 35 is connected to the rear end (the other long side) of the upper plate 34, and the lower end (the other long side) is separated from the bottom plate 31. That is, the length F of the side end (short side) of the baffle plate 35 is shorter than the length G of the side end (short side) of the front plate 32.
The lower end of the baffle plate 35 is preferably located below the air outlet 36 of the front plate 32. Thereby, the rainwater blown into the main body 30 from the air outlet 36 can more reliably collide with the baffle plate 35 and drop to the bottom plate 31 side.

  In the main body 30, the bottom plate 31, the front plate 32, the rear plate 33, the upper plate 34, and the baffle plate 35 are preferably formed of a single steel plate. By forming the main body 30 by using a single plate, it is possible to reduce the labor required to manufacture the main body 30 as compared with the case where the main body 30 is formed by using a plurality of plates. In addition, since the material used is reduced, the weight of the product can be reduced. Further, by using a steel plate, the durability and fire prevention performance of the main body 30 can be increased as compared with the case where a resin is used.

Since the position and size of the drain 47 and the position and size of the projecting piece (drain position limiting portion) 48 are in a corresponding relationship, the drain 47 overlaps with the front plate 32 of the main body 30 and is closed. Is prevented.

6A and 6B are views showing the upper closing body, FIG. 6A is a left side view, and FIG. 6B is a front view.
The upper closing body 50 has an upper closing body front plate 51, an upper closing body rear plate 52, and an upper closing body upper plate 53. At an intermediate position in the longitudinal direction, the upper closing body front plate 51 and the upper closing body rear plate 52 are provided with slits 54. Since the slit 54 is provided, the upper closing body 50 can be bent at an arbitrary angle according to the roof gradient.
The upper closing body front plate 51, the upper closing body rear plate 52, and the upper closing body upper plate 53 are each rectangular and have the same long side length. Both side surfaces of the upper closing body 50 are open.

The upper end (one long side) of the upper closing body front plate 51 is connected to the front end (one long side) of the upper closing body upper plate 53, and the upper closing body rear plate 52 is connected to the rear end (the other long side). Are connected at their upper ends (one long side). The upper closing body front plate 51 and the upper closing body rear plate 52 hang vertically from the upper closing body upper plate 53.
The side end (short side) of the upper closing body front plate 51 is shorter than the side end (short side) of the upper closing body rear plate 52.

  In the upper closing body 50, it is preferable that the upper closing body front plate 51, the upper closing body rear plate 52, and the upper closing body upper plate 53 are formed of a single steel plate. By forming with one plate material, the labor of manufacturing the upper closure 50 can be reduced as compared with the case of forming with a plurality of plate materials. In addition, since the material used is reduced, the weight of the product can be reduced. In addition, by using a steel plate, the durability and fire prevention performance of the upper closing body 50 can be increased as compared with the case where a resin is used.

FIG. 7 is a view showing a state where the upper closing body is attached to the main body.
In the case where a plurality of main bodies 30 are connected and used, a gap is generated in the connecting portion because the mounting angle of one main body 30a is different from that of the other main body 30b in a portion where the roof gradient changes. Therefore, by covering the gap with the upper closing body 50 bent according to the roof gradient, it is possible to prevent rainwater from entering from the gap.
In addition, before the main body 30 is attached, the upper closing body 50 is firstly brought into contact with the field base plate 2 so that the load at the time of construction can be reduced and more reliable water stoppage is possible.
