The second side portion 33 faces the second ventilation material 22. The cap tree 3 is mounted on the wall body 2 via a cap tree mounting member screwed onto the horizontal furring strip 13.

Next, the configuration of the first ventilation material 21 will be described in detail with reference to FIGS. 2 (a) and 2 (c). Since the first ventilator 21 and the second ventilator 22 have the same configuration and the wall 1 has a symmetrical configuration in FIG. 1, the configuration around the second ventilator 22 and the second ventilator 22 will be described below. The explanation may be omitted. FIG. 2B is a partially enlarged view of a cross section taken along the line IIB-IIB of FIG. 2C.

As shown in FIG. 2A, the first ventilation material 21 is formed by bending a single rectangular strip-shaped metal plate at a plurality of locations. The first ventilation material 21 includes a Kasagi facing portion 41 extending in the left-right direction in FIG. 2A, a front hanging plate portion 42 extending downward from the left end of the Kasagi facing portion 41, and a front hanging plate portion 42. It has a lower plate portion 43 extending in a direction away from the front hanging plate portion 42 from the same height as the lower end, and a parting plate portion 44 extending downward from the lower end of the front hanging plate portion 42.

The Kasagi facing portion 41 has a plate-shaped first extending portion 51 extending in the horizontal direction and a plate-shaped second extending portion 52 folded back at the right end thereof and stacked downward. The first extending portion 51 and the second extending portion 52 extend in the left-right direction and are connected to each other at the right ends. From the left end of the first extending portion 51, the front hanging plate portion 42 extends downward. The second extending portion 52 is shorter than the first extending portion 51 and extends to the front of the left end of the first extending portion 51. The first shielding portion 61 projects downward from the left end of the second extending portion 52. The Kasagi facing portion 41 is nailed to the lateral furring strip 13 at a portion to the right of the Kasagi facing portion 41 (see FIG. 1).

As shown in FIG. 2A, the lower plate portion 43 is connected to the front hanging plate portion 42 via the parting plate portion 44. The lower plate portion 43 is arranged so as to face below the Kasagi facing portion 41 and extend to the right of the first shielding portion 61 so as to form a ventilation path, and approach the Kasagi facing portion 41 as the distance from the front hanging plate portion 42 increases. It is inclined like. From the right end of the lower plate portion 43, the second shielding portion 62 projects upward toward the Kasagi facing portion 41 to prevent rainwater or the like from entering the inside.

The parting plate portion 44 continuously extends downward from the lower end of the front hanging plate portion 42, and is folded upward at the lower ends of the first parting plate portion 71 and the first parting plate portion 71 forming one flat surface with the front hanging plate portion 42. It has a second parting portion 72 that is overlapped with each other. The first parting portion 71 and the second parting portion 72 face each other in the left-right direction in FIG. 2A and are connected to each other at the lower ends. A lower plate portion 43 is connected to the upper end of the second parting portion 72 so as to extend to the right.

As shown in FIG. 2A, the first parting portion 71 extends downward from the lower end of the front hanging plate portion 42. The upper end of the second parting portion 72 is connected to the left end of the lower plate portion 43.

As shown in FIGS. 2 (b) and 2 (c), a plurality of ventilation holes 81 are formed in the front hanging plate portion 42. The ventilation hole 81 is a vertically elongated hole extending from the upper portion of the front hanging plate portion 42 to the upper end portion of the first parting portion 71. As shown in FIG. 2C, the ventilation holes 81 are arranged at predetermined intervals in the longitudinal direction of the first ventilation material 21.

As shown in FIGS. 2 (b) and 2 (c), the ventilation hole 81 has an upper hole portion 82 formed in the front hanging plate portion 42 and a lower hole portion 83 formed in the first parting portion 71. Have. Since the ventilation hole 81 is not formed in the second parting portion 72, the lower hole portion 83 is closed by the second parting portion 72 in the front view of the ventilation material (see FIG. 2C). I can see it.

As shown in FIG. 2 (a), since the lower plate portion 43 is inclined and the second shielding portion 62 is provided at the right end thereof, the upper hole portion 82 of the ventilation hole 81 shown in FIG. 2 (b) is provided. Even if rainwater or the like infiltrates from the air, it is possible to prevent rainwater or the like from invading into the first ventilation passage A ₁ (see FIG. 1), and the rainwater or the like heads toward the ventilation hole 81 along the inclined surface of the lower plate portion 43. It flows back and is discharged from the ventilation hole 81 (see FIG. 2B). Further, since the prepared hole portion 83 is provided, the infiltrated rainwater or the like can be discharged more reliably, and the moisture can be less likely to remain inside the first ventilation material 21 (inside the ventilation passage).

A corner portion C is formed in the first ventilation material 21 by the lower plate portion 43 and the second parting portion 72 (see FIG. 2B). At the corner C, a water blocking material 100 is attached to the lower surface of the lower plate portion 43. The water blocking material 100 extends in the longitudinal direction of the first ventilation material 21. The water blocking material 100 is formed of, for example, ethylene propylene diene rubber (EPDM). Further, as the water blocking material 100, in addition to other rubber-like members and foaming bodies, known water stopping packing materials and the like can be widely used.

In the first ventilation material 21, as shown in FIG. 1, the lower plate portion 43 is placed on the upper end of the first exterior material 17 via the water blocking material 100, and the second parting portion 72 is the second. 1 It is arranged on the first exterior material 17 so as to be along the outer surface of the exterior material 17. The cap tree facing portion 41 is arranged so as to face the upper portion 31 of the cap tree, and is screwed to the horizontal furring strip 13. The second ventilation material 22 is similarly arranged at the upper end of the second exterior material 19.

As a result, the parting plate portion 44 (second parting portion 72) of the first ventilation material 21 is substantially adjacent to the outer surface of the first exterior material 17. Further, the parting plate portion 44 of the second ventilation material 22 is substantially adjacent to the outer surface of the second exterior material 19. As a result, even if the first ventilation material 21 and the second ventilation material 22 are arranged on the wall body 2, the width of the wall body 2 does not substantially increase, and the width size of the cap tree 3 covering the upper ends thereof is increased. It is not necessary to use a wall body 2 that is particularly wide with respect to the width of the wall body 2.

Since the space between the lower plate portion 43 and the upper end of the first exterior material 17 is sealed by the water blocking material 100, rainwater, moisture, etc. do not enter the inside of the wall body 2 from between them. The water blocking material 100 is pressed by the lower plate portion 43 of the first ventilation material 21 and compressed in the vertical direction in FIG. 1 by a predetermined dimension or more to exert a water blocking effect.

When a gap is formed between the parting plate portion 44 (second parting portion 72) and the outer surface of the first exterior material 17, a part of the water blocking material 100 is on the outer surface of the first exterior material 17. Even if it protrudes to the outside from the extension surface, the water blocking material 100 cannot be seen hidden by the parting plate portion 44 in the front view of the wall 1.

Further, since the first side portion 32 of the Kasagi 3 extends to a height lower than the lower end of the parting plate portion 44 of the first ventilation material 21, rainwater reaches the ventilation hole 81 of the first ventilation material 21 (FIG. 2 (b). ) Or between the first ventilation material 21 and the first exterior material 17 (see FIG. 1). Further, since the second side portion 33 of the Kasagi 3 also extends to a height lower than the lower end of the parting plate portion 44 of the second ventilation material 22, rainwater reaches the ventilation hole 81 (see FIG. 2B) or the first. 2 It is difficult to penetrate from between the ventilation material 22 and the second exterior material 19 (see FIG. 1).

In the first ventilation material 21, a ventilation path is formed between the Kasagi facing portion 41 and the lower plate portion 43. The ventilation path meanders by the first shielding portion 61 and the second shielding portion 62. As a result, even if rainwater or the like enters the first ventilation material 21 from the ventilation hole 81 shown in FIG. 2B, the rainwater or the like collides with the first shielding portion 61 and the second shielding portion 62, and the first exterior It can be prevented from entering into the first air passage a ₁ on the inside of the timber 17. On the other hand, the outside air that has entered through the ventilation hole 81 flows through the ventilation passage in the first ventilation material 21 to the first ventilation passage A ₁ inside the first exterior material 17, and flows to the outside of the wall 1 and the first exterior. Ventilation with the inside of the material 17 is performed.

As described above, according to the present embodiment, the following effects are obtained.
When the first ventilation material 21 is arranged at the upper end of the first exterior material 17 so that the lower plate portion 43 faces the upper end of the first exterior material 17, the parting plate portion 44 hides the upper end edge of the first exterior material 17. Therefore, even if the upper end edge of the first exterior material 17 is uneven, the appearance of the wall 1 is not impaired. Further, since the water blocking material 100 arranged along the outer surface of the first exterior material 17 is not visible by the parting plate portion 44, the appearance of the wall 1 is not spoiled. Further, even if the water blocking material 100 is pressed against the first ventilation material 21 and protrudes to the outside from the extension surface of the outer surface of the first exterior material 17, the water blocking material 100 is hidden by the parting plate portion 44, so that the wall The appearance of 1 is preferable. Further, since the water blocking material 100 does not protrude around the ventilation hole 81 by the lower plate material 43 and the parting plate portion 44, it is possible to prevent the ventilation hole 81 from being blocked by the water blocking material 100.

Further, by attaching the water blocking material 100 to the first ventilation material 21 in advance, when assembling the ventilation structure shown in FIG. 1, the work of arranging the sealing material (caulking material) at the upper end of the first exterior material 17 is omitted. it can. Therefore, the workability can be improved.

Further, since the ventilation hole 81 extends from the front hanging plate portion 42 to the first parting portion 71, rainwater or the like that has entered the inside of the first ventilation material 21 is likely to be discharged from the ventilation hole 81. On the other hand, since the ventilation hole 81 is not formed in the second parting portion 72 facing the first parting portion 71, rainwater or the like is discharged from the prepared hole portion 83 formed in the first parting portion 71 of the first ventilation material 21. It can be prevented from entering the inside.

Further, since the lower plate portion 43 is inclined so as to approach the Kasagi facing portion 41 as the distance from the front hanging plate portion 42 increases, rainwater or the like that has entered the inside of the first ventilation material 21 is used for the inclination of the lower plate portion 43. It is easy to lead toward the ventilation hole 81 (see FIG. 2B). Therefore, rainwater or the like in the first ventilation material 21 is likely to be discharged to the outside.

Further, since the first ventilation material 21 and the second ventilation material 22 are covered by the upper portion 31, the first side portion 32, and the second side portion 33 of the Kasagi 3, the first ventilation material 21 and the first exterior material 17 It is possible to prevent rainwater or the like from entering the inside of the wall body 2 from between the second ventilation material 22 and the second exterior material 19.

For example, in the above-described embodiment, the water blocking material 100 is attached to the lower plate portion 43 at the corner C between the lower plate portion 43 and the parting plate portion 44 of the first ventilation material 21, but the water blocking material 100 The mounting position can be changed. For example, the water blocking material 100 may be attached to the parting plate portion 44. Further, the water blocking material 100 may be attached to both the lower plate portion 43 and the parting plate portion 44.

Further, the water blocking material 100 may not be attached to the first ventilation material 21. In this case, it is preferable to arrange a caulking material (sealing material) or the like as a water blocking material between the first exterior material 17 and the first ventilation material 21. Similarly, the water blocking material 100 may not be attached to the second ventilation material 22. In this case, it is preferable to arrange a caulking material or the like between the second exterior material 19 and the second ventilation material 22.
