  In the configuration of Patent Document 1, it is not possible to collect rainwater adhering to the outer surface of the lower front wall. In other words, there is room for improvement in order to suppress the occurrence of raindrops falling down the eaves along the outer surface of the eaves wall.

  An object of the present invention is to obtain an eaves ridge that can suppress the occurrence of raindrops that fall down under the eaves along the outer surface of the side wall of the eaves ridge.

  The eaves wall according to the first aspect includes a vertical wall provided along the outer wall of the building and a side wall facing the vertical wall in the depth direction, and collects rainwater. A first water collecting part, and a second water collecting part which is provided integrally with the first water collecting part below the first water collecting part and collects rainwater flowing along the outer side surface of the side wall. Part.

  In the eaves wall according to the first aspect, rainwater is collected in the first water collecting section. Here, the rainwater blown into the side wall of the first water collecting portion flows along the outer surface of the side wall of the first water collecting portion. And the rainwater which flowed along the outer surface is collected by the 2nd water collection part provided in the lower side rather than the 1st water collection part. This reduces the amount of rainwater that falls from the outer side surface of the side wall of the first water collecting unit to the lower side of the eaves as compared to the configuration without the second water collecting unit. It is possible to suppress the occurrence of dripping rain.

  The bottom of the first water collecting portion of the eaves bowl according to the second aspect extends below the first water collecting portion, and the rain water of the first water collecting portion flows down to the second water collecting portion side. A first tube portion is provided, and the bottom portion of the second water collection portion extends below the second water collection portion, and the first tube portion is inserted with a gap between the second water collection portion and the second water collection portion. A second cylinder part is provided for allowing rainwater in the water part to flow down into the vertical gutter.

  In the eaves wall according to the second aspect, rainwater from the first water collecting portion flows in the first tube portion and flows down into the vertical rod, and rainwater from the second water collecting portion flows in the second tube portion. It flows down in. Here, since the 1st cylinder part is inserted in the 2nd cylinder part, it is suppressed that the rainwater which flowed in the 1st cylinder part flows in into a 2nd water collection part. In addition, since the first tube portion and the second tube portion are arranged with a gap therebetween, the negative pressure generated when the rainwater that has flowed through the first tube portion flows into the vertical shaft causes the second water collecting portion to Rain water is sucked into the gap between the first tube portion and the second tube portion. Thereby, compared with what does not have this structure, the quantity of the rainwater which remains in a 2nd water collection part can be reduced.

  A guide surface for guiding rainwater that has flowed on the outer surface to the outer wall side is formed at the lower end of the side wall of the eaves wall according to the third aspect.

  In the eaves wall according to the third aspect, the rainwater that has flowed through the outer side surface of the side wall of the first water collecting portion and reached the guide surface is guided by the guide surface and flows toward the outer wall side of the building. This prevents rainwater from staying at the lower end of the side wall compared to a configuration in which a corner is formed at the lower end of the side wall, thereby suppressing the occurrence of rainwater (rain dripping) from the lower end of the side wall to the eaves. can do.

  The width in the depth direction of the upper end of the second water collecting portion of the eaves bowl according to the fourth aspect is shorter than the width in the depth direction of the lower end of the first water collecting portion.

  In the eaves bowl according to the fourth aspect, since the width in the depth direction of the upper end of the second water collecting portion is shorter than the width in the depth direction of the lower end of the first water collecting portion, the curve direction of the side wall of the first water collecting portion Or it becomes possible to arrange | position the side wall of a 2nd water collection part along an inclination direction. Thereby, when the eaves bowl is viewed in the depth direction, the first water collection section and the second water collection section are easily recognized as one member, so that the appearance of the eaves bowl can be improved.

  The eaves trap according to the first aspect has an excellent effect that it is possible to suppress the occurrence of rain dripping falling down the eaves along the outer surface of the eaves side wall.

  The eaves bowl according to the second aspect has an excellent effect that the amount of rainwater remaining in the second water collecting section can be reduced.

  The eaves trap according to the third aspect has an excellent effect that it is possible to suppress the occurrence of raindrops falling from the lower end of the side wall to the eaves.

Here, in the eaves basket 60, the 1st cylinder member 66 is made to flow down the rainwater of the 1st water collection part 62 to the 2nd water collection part 64 side (vertical rod 18). In addition, the second cylinder member 68 allows the rainwater in the second water collecting portion 64 to flow down to the downpipe 18.

[Action]
Next, the operation of this embodiment will be described.

  FIG. 7 schematically shows a part of the flow of rainwater in the eaves structure 40. In addition, in FIG. 7, illustration of a part of draining material 50 and the hanging tool 52 (refer FIG. 2) is abbreviate | omitted.

  In the eaves structure 40, rainwater A (indicated by an arrow A) flows on the upper surface of the inclined portion 50B of the draining material 50 during rain. This rainwater A falls from the tip of the inclined part 50B into the first water collecting part 62 of the eaves 60 and is collected. Further, rainwater B (indicated by an arrow B) that has fallen inside the curved wall 62C of the first water collecting portion 62 is collected by the first water collecting portion 62 along the inner side surface 62I of the curved wall 62C.

  Rainwater C (indicated by an arrow C) blown into the curved wall 62C of the first water collecting portion 62 from the outside flows along the outer surface 62H of the curved wall 62C by the action of the gravity force. The rainwater C that has flowed along the outer surface 62H is guided to the lower surface 62G of the bottom wall 62B by the guide surface 63. On the lower surface 62 </ b> G, rainwater C collects and rains and falls into the second water collecting portion 64. The rainwater C is collected by a second water collection unit 64 provided below the first water collection unit 62.

  Thus, in the eaves 60, since the rainwater C adhering to the outer surface 62H is collected by the second water collecting portion 64, it is not shown from the outer surface 62H as compared with the configuration without the second water collecting portion 64. The amount of rainwater C falling below the eaves is reduced. That is, in the eaves cage 60, compared to a configuration without the second water collecting portion 64, it is possible to suppress the occurrence of raindrops falling on the eaves 13 (see FIG. 1) along the outer side surface 62H.

  In addition, as shown in FIG. 6B, in the eaves cage 60, rainwater A and B in the first water collecting portion 62 flows through the first cylindrical member 66 and flows down into the vertical rod 18, and the second collection. Rainwater C in the water portion 64 flows through the second cylindrical member 68 and flows down into the vertical rod 18. Here, the tubular portion 66 </ b> A of the first tubular member 66 is inserted into the tubular portion 68 </ b> A of the second tubular member 68. That is, the rainwaters A and B flowing down in the first cylindrical member 66 are discharged from the cylindrical portion 66A below the bottom wall 64A of the second water collecting portion 64, and thus flowed in the first cylindrical member 66. It is suppressed that rain water A and B flows in into the 2nd water collection part 64. FIG.

  Further, in the eaves 60, the cylindrical portion 66A of the first cylindrical member 66 and the cylindrical portion 68A of the second cylindrical member 68 are arranged with a gap d2 (see FIG. 6A). Here, the rainwaters A and B that have flowed through the cylindrical portion 66A flow down into the vertical gutter 18, whereby the air in the vertical gutter 18 is pushed out downward. As a result, a negative pressure is generated in the space between the tube portion 66A and the tube portion 68A. Due to this negative pressure, rainwater C (atmospheric pressure state) in the second water collecting portion 64 is sucked between the tubular portion 66A and the tubular portion 68A. As described above, in the eaves basket 60, the rainwater C is sucked using the negative pressure generated in the gap between the tube portion 66A and the tube portion 68A. The amount of rainwater C remaining in the portion 64 can be reduced.

  In addition, in the eaves cage 60 shown in FIG. 7, the rainwater C that has flowed through the outer side surface 62H of the first water collecting portion 62 and reached the guide surface 63 is the guide surface 63 formed of a curved surface, as described above. And flows toward the outer wall member 24 (see FIG. 2). This prevents rainwater C from staying at the lower end of the curved wall 62C as compared to the configuration in which the corner is formed at the lower end of the curved wall 62C. ) Can be prevented from falling (rain dripping). Further, since the bottom wall 62B is inclined at an angle θ (see FIG. 5) with respect to the horizontal plane M (see FIG. 5), the rainwater C reaching the guide surface 63 is on the outer wall material 24 side (vertical wall 62A side) of the lower surface 62G. ) And the retention of rainwater C on the guide surface 63 can be suppressed.

  In addition, as shown in FIG. 2, in the eaves cage 60, the width L2 in the X direction at the upper end in the Z direction of the second water collecting portion 64 is larger than the width L1 in the X direction at the lower end in the Z direction of the first water collecting portion 62. short. For this reason, it is possible to arrange the curved wall 64B of the second water collecting portion 64 on a line (not shown) indicating the bending direction of the curved wall 62C of the first water collecting portion 62 (along the bending direction). . Thereby, when the eaves 60 is viewed toward the indoor side in the X direction, the second water collecting portion 64 does not protrude to the near side of the first water collecting portion 62, and the first water collecting portion 62 and the second water collecting portion 62 Since the water collection part 64 becomes easy to be recognized as one continuous member, the appearance of the eaves basket 60 can be improved.

  In addition, this invention is not limited to said embodiment.

The second water collecting part 84 of the eaves 80 has a three-stage configuration of an upper water collecting part 86, a middle water collecting part 88, and a lower water collecting part 92. That is, the eaves 80 is composed of a total of four water collecting sections as an example.

  The first water collecting portion 82 includes a vertical wall 82A along the YZ plane, a bottom wall 82B extending outward from the Z-direction upper portion of the vertical wall 82A along the X direction, and an X-direction outer end portion of the bottom wall 82B. And a curved wall 62C extending in an oblique direction. The vertical wall 82A is formed in a plate shape whose X direction is the plate thickness direction, and is disposed on the building 10 (see FIG. 2) side. A groove 62D is formed at the upper end of the vertical wall 82A in the Z direction. The vertical wall 82A and the curved wall 62C face each other in the X direction.

  Further, the vertical wall 82 </ b> A extends to the lower water collecting portion 92 below the first water collecting portion 82 in the Z direction, and also constitutes a part of the second water collecting portion 84. A through hole 82C penetrating in the Z direction is formed on the vertical wall 82A side of the bottom wall 82B in the X direction center. A guide surface 63 is formed outside a portion where the bottom wall 82B and the curved wall 62C are connected.

  The upper water collecting portion 86 includes a vertical wall 82A, a bottom wall 86A extending outward along the X direction from the center portion in the Z direction of the vertical wall 82A, and a curved wall extending obliquely from the X direction outer end portion of the bottom wall 86A. 86B. A through-hole 86C penetrating in the Z direction is formed on the vertical wall 82A side of the bottom wall 86A in the X direction center. A guide surface 63 is formed outside the portion where the bottom wall 86A and the curved wall 86B are connected. The vertical wall 82A and the curved wall 86B are opposed to each other in the X direction. The upper end in the Z direction of the curved wall 86B is disposed at a distance from the bottom wall 82B. Further, the length in the X direction from the upper end in the Z direction of the curved wall 86B to the vertical wall 82A is shorter than the length in the X direction of the bottom wall 82B.

  The middle water collecting portion 88 includes a vertical wall 82A, a bottom wall 88A extending outward along the X direction from the lower side of the central portion in the Z direction of the vertical wall 82A, and an oblique direction from the X direction outer end portion of the bottom wall 88A. And a curved wall 88B extending in the direction. A through hole 88C penetrating in the Z direction is formed on the vertical wall 82A side of the bottom wall 88A in the X direction center. A guide surface 63 is formed outside the part where the bottom wall 88A and the curved wall 88B are connected. The vertical wall 82A and the curved wall 88B are opposed to each other in the X direction. The upper end in the Z direction of the curved wall 88B is disposed at a distance from the bottom wall 86A. Further, the length in the X direction from the upper end in the Z direction of the curved wall 88B to the vertical wall 82A is shorter than the length in the X direction of the bottom wall 86A.

  The lower water collecting portion 92 includes a vertical wall 82A, a bottom wall 64A extending outward from the lower end in the Z direction of the vertical wall 82A along the X direction, and a curved wall 64B. The vertical wall 82A and the curved wall 64B are opposed to each other in the X direction. The upper end in the Z direction of the curved wall 64B is disposed with a space from the bottom wall 88A. The length in the X direction from the upper end in the Z direction of the curved wall 64B to the vertical wall 82A is shorter than the length in the X direction of the bottom wall 88A. A second cylindrical member 68 is attached to the through hole 64C of the bottom wall 64A. The second cylinder member 68 is attached to the vertical rod 18. The through holes 82C, 86C, 88C, and 64C are formed at positions that overlap when viewed in the Z direction.

  Here, in the eaves 80, rainwater collected by the first water collecting portion 82 at the time of rain flows to the upper water collecting portion 86 through the through hole 82C. Further, rainwater blown into the curved wall 62 </ b> C flows along the outer side surface 62 </ b> H and the guide surface 63 and is collected by the upper water collecting portion 86. Rainwater collected by the upper water collecting portion 86 flows to the middle water collecting portion 88 through the through hole 86C. The rainwater blown into the curved wall 86B flows along the outer surface 86D and the guide surface 63 of the curved wall 86B and is collected by the middle water collecting portion 88.

  Rainwater collected by the middle water collecting portion 88 flows to the lower water collecting portion 92 through the through hole 88C. The rainwater blown into the curved wall 88B flows along the outer surface 88D and the guide surface 63 of the curved wall 88B, and is collected by the lower water collecting portion 92. The rainwater flowing through the first water collecting portion 82, the upper water collecting portion 86 and the middle water collecting portion 88 and the rainwater collected by the lower water collecting portion 92 pass vertically through the inside of the second cylindrical member 68. It flows into the pot 18.

  Thus, in the eaves 80, since the second water collection part 84 is configured in a plurality of stages (three stages), compared to the case where the second water collection part 84 is configured only by the lower water collection part 92, The volume of the 2nd water collection part 84 is large. That is, the second water collecting part 84 can suppress rain dripping from the first water collecting part 82, and can improve the rain water collecting (collecting) ability in the second water collecting part 84. Further, in the eaves bowl 80, the length (finding) in the X direction is shorter in the X direction than the upper side from the first water collection section 82 to the lower water collection section 92. When viewed in the direction, the first water collecting portion 82 and the second water collecting portion 84 are easily recognized as one member. Thereby, the appearance of the eaves bowl 80 can be improved.
