  Thereby, in the building 10 in which the lower house 18 is provided, the water blocking plate 20 is straddled so as to straddle the boundary part between the outer wall panel 14 and the roof covering 40 at the boundary between the outer wall panel 14 and the roof covering 40 of the lower house 18. The upper draining portion 30 and the lower draining portion 42 of the draining plate 22 are covered.

  Here, the water stop plate 20 is disposed in the slit 24 so that the flat portion 26 penetrates the outer wall member 16, and the upper draining portion 30 is continuous from the flat portion 26 along the surface on the outdoor side of the outer wall member 16. Is drooping. Further, in the water blocking plate 20, a vertical plate portion 28 continuous from the flat portion 26 to the indoor side protrudes upward along the indoor side surface of the outer wall material 16. For this reason, even if raindrops or the like adhering to the outdoor surface of the outer wall material 16 of the outer wall panel 14 flow indoors from the slit 24 along the flat portion 26, they are dammed in the vertical plate portion 28. Thereby, it is possible to prevent rain leakage from occurring on the indoor side of the outer wall member 16 from the boundary portion between the outer wall member 16 of the outer wall panel 14 and the roof covering member 40 of the lower house 18. And since the water stop material 34 is packed between the vertical board part 28 and the outer wall material 16, it can suppress that a wind blows from the slit 24 of the outer wall panel 14, and it blown from the slit 24. Even if raindrops or the like are pushed up along the vertical plate portion 28 by the wind, the pushed raindrops or the like can be blocked by the water blocking material 34, and the raindrops or the like wrap around the indoor side of the outer wall panel 14. Can be prevented.

  Further, a lower draining portion 42 of the draining plate 22 is provided below the upper draining portion 30 of the water stop plate 20, and raindrops attached to the upper draining portion 30 fall on the lower draining portion 42. . In the draining plate 22, the overlapping portion 46 on the outer wall panel 14 side of the lower draining portion 42 is raised, and the upper engaging portion 48 of the overlapping portion 46 is connected to the upper draining portion 30 and the folded portion 32 of the water stop plate 20. It is inserted between. For this reason, it becomes easy to attach the draining plate 22, and it is possible to easily perform the rain closing process between the outer wall panel 14 and the lower house 18. In addition, since the space between the overlapping portion 46 and the upper draining portion 30 is closed, it is possible to prevent the blowing of wind and the entry of raindrops.

  Furthermore, a waterstop material 56 is packed between the lower draining portion 42 of the draining plate 22 and the roof covering material 40, and raindrops or the like travel along the upper surface of the roof covering material 40 to the outer wall panel 14 (outer wall material 16). Infiltration into the side is suppressed. In addition, a draining portion 44 is provided below the outer wall material 16 and the roof covering 40, and a water return portion 54 is provided below the roof covering 40 in the draining portion 44. In addition, a vertical plate portion 52 is provided on the outer wall panel 14 side. For this reason, even if raindrops or the like fall from the end of the roof covering 40 on the outer wall panel 14 side to the draining section 44, it can be prevented from flowing out of the draining section 44, and rain leakage or the like occurs in the lower house 18. Can be prevented.

  Therefore, in the building 10, it is possible to prevent rainwater from infiltrating indoors from the outer wall panel 14 (14 </ b> A to 14 </ b> C) to which the lower house 18 is connected, and to prevent rain leakage or the like from occurring in the lower house 18.

  In addition, since the water stop plate 20 is attached to the outer wall panel 14 in advance, the work at the construction site for the rain ending is the processing and attachment of the draining plate 22, so the work for the rain ending of the lower house 18 is completed. Man-hours can be reduced. Furthermore, in the operation of attaching the draining plate 22 to the water stop plate 20, the operation of locking the engaging portion 48 of the water drain plate 22 to the water stop plate 20 is sufficient. For this reason, it is possible to suppress the use of nails for fixing the water stop plate 20 and the water drain plate 22, and a sealing process for raining around the water stop plate 20 and the water drain plate 22 is compared to the conventional one. (Compared to the case where no water structure is applied). Thereby, the work man-hour for attachment of the draining board 22 and rain closing can be reduced, and rain closing processing can be made easy.

  In addition, when nails are used to attach sheet metal for rain, it is necessary to seal the head of the nail and around the head to prevent rainwater from entering around the nail and corrosion of the nail. . On the other hand, in the water stop structure according to the present embodiment, since the use of nails or the like can be suppressed, the number of man-hours for the sealing process can be reduced. In addition, when the sealing process is performed, maintenance for replacing the sealing material is required, but maintenance such as replacement of the sealing material can be suppressed, and the rain performance can be maintained for a long time.

  In addition, in this Embodiment demonstrated above, although the vertical board part 28 was provided in the indoor side of the water stop board 20, the structure which does not provide the vertical board part 28 may be sufficient. In this case, the flat portion 26 is fixed to the outer wall member 16 or the outer wall frame on the indoor side of the outer wall member 16, and a sponge-like (elastic body) water-stop material is filled between the flat portion 26 and the inner surface of the slit 24. Then, water treatment can be applied.

  Moreover, in this Embodiment, although the draining board 22 which integrated the draining member and the draining member was used, the draining member and the draining member may be a different body.
