That is, while air is taken in from the back of the eaves of the one-story one-story building, exhaust is made from the joint structure K. Further, since the air flow path is configured as described above, the rainwater flowing through the upper drainage 3 is drained from the upper drainage 3 to the roof R, and there is no possibility that the rainwater enters the back of the roof R. Therefore, drainage of the joint between the roof R of the one-story one-story roof and the outer wall W of the second floor is ensured.

As described above, according to this embodiment, the roof R of the one-story one-story house and the outer wall surface W of the second-story house are provided in the same manner as the conventional double drainer.
While the drainage at the junction with ₁ is ensured, ventilation divided into intake and exhaust can be performed on the back of the roof R of the one-story one-story building.

As described above, the present invention has been described based on the embodiments, but the present invention is not limited to only such embodiments. For example, in the embodiment, the case where the structure of the present invention is applied to the joint between the roof of the one-story one-story roof and the outer wall of the second floor has been described. However, the joint structure of the present invention is applied only to the above. However, the present invention can be suitably applied to the same type of bonding.

[0027]

As described above in detail, the joint structure of a building according to the present invention ensures drainage of the joint between the roof and the upper floor outer wall of the roof in the same manner as the conventional double drainage. It has an excellent effect that ventilation can be divided into intake and exhaust.
