  FIG. 3 is a partial perspective view of the roof structure 1 and is a partial perspective view in which the cross section of the water guide plate 10 is visible. FIG. 4 is a schematic cross-sectional view when a part of the roof structure 1 is cut along the YZ plane. In FIG. 3, the upper surface 5 a of the field board 5 is indicated by diagonal lines for easy understanding of the drawing. As shown in FIG. 3, in the cross section perpendicular to the Y direction, the ridge portion 15 is formed by an integral bent plate portion having two bent portions and defining three directions of a substantially rectangular space 8. The Specifically, the protrusion 15 has an eaves side wall 15a, an upper side plate 15b, and a ridge side wall 15c, and the eaves side wall 15a is a ridge side end of the bottom side plate 18 including the upper surface 11 in the Y direction. Extends in the Z direction. Further, the upper side plate portion 15b extends from the upper end portion of the eaves side wall portion 15a to the ridge side in the Y direction, and the ridge side wall portion 15c extends from the ridge side end portion in the Y direction of the upper side plate portion 15b to the lower side in the Z direction. Extend. The lower end of the ridge side wall 15c in the Z direction is connected to the eaves end of the bottom plate 18 in the Y direction. The bottom surface of the bottom side plate portion 18 is in contact with the upper surface 5 a of the field plate 5. By configuring the ridge portion 15 with a bent plate portion having two bent portions, the rigidity of the ridge portion 15 is increased so that the ridge portion 15 is not easily damaged even when an external force is applied. .

  As shown in FIG. 3, the roof structure 1 further includes an eaves drainer 25. The eaves tip drainer 25 is installed on the eaves side of the plurality of ridges 15 of the water guide plate 10 with respect to the ridges 15 located closest to the eaves. The eaves tip drainer 25 is connected to the lower end portion of the water guide plate 10, and includes an inclined portion 25 a extending obliquely downward from the eaves tip of the field plate 5. The eaves drainer 25 is attached to the water guide plate 10 as follows, for example. Specifically, as shown in FIG. 4, the eaves tip drainer 25 has a plate-like portion 25b placed on the upper surface 5a of the base plate 5 and a fixing portion 25c protruding from the plate-like portion 25b in the Z direction. The part 25c extends in the X direction. Moreover, the water guide plate 10 has the fixing | fixed part 23 which protrudes in a Z direction in the eaves side edge part of a Y direction, and the fixing | fixed part 23 is extended in the X direction. Further, the water guide plate 10 further includes a long cap 29. By fitting the cap 29 into the fixing portion 25c and the fixing portion 23 so that the pair of inner side surfaces of the cap 29 are in contact with the outer surface of the fixing portion 25c and the outer surface of the fixing portion 23, the eaves drainer 25 is guided to the water. Attach to plate 10. The eaves drainer 25 is provided to prevent rainwater that has traveled through the water guide plate 10 from flowing toward the base plate 5, and to prevent water from entering the inside of the building via the base plate 5. Provided. The eaves drainer 25 is a separate member from the water guide plate 10 and the eaves tip drainer 25 is fixed to the water guide plate 10. However, the eaves drainer may be formed integrally with the water guide plate.

  As described above, the roof structure 1 includes the water guide plate 10 that is disposed on the upper side of the building, has one or more protrusions 15 that extend substantially in the X direction, and is installed on the upper side of the eaves. Moreover, the roof structure 1 is provided with the eaves tip draining 25 installed in the eaves side rather than the protrusion part 15 located in the eaves side most.

  According to this structure, the water guide plate 10 is provided with the protrusion 15 extended in the orthogonal direction (X direction) orthogonal to the eaves-ridge direction (Y direction). Therefore, the rainwater flowing downward in the Y direction can be blocked by the ridges 15, and the rainwater blocked can be allowed to flow in the X direction so as to travel along the ridges 15. Can be collected at the side end of one side. And the rain water collected at the side edge part of one side can be guide | induced to the lower side through the water catchment provided in the appropriate location of the side edge part of one side. Therefore, since the eaves part 15 can be made to play the role of the eaves part 15, an eaves can be abbreviate | omitted, a building can be made stylish and excellent in aesthetics, and can be comprised compactly.

  Moreover, since the roof structure 1 has the eaves edge drainer 25 arrange | positioned at the eaves side of a Y direction, the rain water on the water guide board 10 can be reliably flowed through the eaves edge drainer 25 to the ground side, and the water guide board 10 It is possible to substantially prevent the upper rainwater from flowing to the base plate 5 side. Therefore, it is possible to substantially prevent rainwater on the water guide plate 10 from entering the inside of the building via the field plate 5.

  Moreover, the roof structure 1 is arrange | positioned between the decorative member 30 and the water guide plate 10 regarding the Y direction, and the decorative member 30 arrange | positioned so that it may extend from the ridge side to the eaves side at a side edge part, A drainage channel 38 extending to the side may be provided. The roof structure 1 is configured integrally with the lower end portion of the decorative member 30, and drains so that at least a part of the water collection port 37 is adjacent to the lower end portion of the drainage channel 38 in the extending direction of the drainage channel 38. There may be provided a water collecting rod 35 that is disposed below the path 38 and to which a rod is connected.

  According to the above configuration, the rainwater collected at the side end portion on one side so as to be transmitted through the ridge portion 15 can flow to the eaves in the Y direction via the drainage channel 38, and then the water collection It can be made to flow downward on the ground or the like through the ridge 35. Therefore, rainwater can flow smoothly to the ground side.

  Further, since the catchment basin 35 is arranged on the eaves side with respect to the drainage channel 38 so as to be adjacent to the lower end of the drainage channel 38 extending to the vicinity of the eaves end, the protrusion 15 is formed to the eaves side end. However, it is possible to cause the rainwater that has traveled through the ridges 15 to flow toward the catchment basin 35. Therefore, more rainwater can be collected in the catchment bar 35.

  Furthermore, in the cross section in the YZ plane, the protrusion 15 may be formed of a bent plate portion having two bent portions and defining three directions of a substantially rectangular space.

  According to the said structure, since the protrusion part 15 has two bending parts, the rigidity of the protrusion part 15 can be enlarged. Therefore, even if an external force acts on the ridge portion 15, the ridge portion 15 is unlikely to be damaged such as deformation. In addition, with reference to FIG. 3, while the eaves side wall part 15a and the bottom side board part 18 may be connected by a curved board part, the ridge side wall part 15c and the bottom side board part 18 may be connected by a curved board part. Thus, it is preferable to provide a radius between the eaves side wall part 15a and the ridge side wall part 15c and the bottom side plate part 18 because the rigidity of the ridge part 15 can be further increased.

The water guide plate 110 has a groove portion 116 that exists between the ridge portions 115 adjacent in the Y direction. In the bottom plate portion 140 of the water guide plate 110, one end portion in the X direction of the portion corresponding to the groove portion 116 is cut obliquely downward. The cut-and-raised part 171 inclined obliquely below constitutes a water guide part that guides the water flowing in the groove part 116 along the ridge part 115 to the water collecting port 137 side of the water collecting bar 135. The cut-and-raised part 171 is formed by, for example, press forming, by cutting the bottom plate part 140 along the ridge 115 and then bending the cut part.

  The lower drainer 127 is an integral plate member made of metal or the like. The lower drainer 127 is disposed on the back side of the water guide plate 110 and guides the water that has reached the upper surface thereof to the water collecting port 137 of the water collecting bowl 135. Specifically, as shown in FIG. 6, the lower drainer 127 has an inclined plate portion 127 a that is inclined so as to move downward as it goes in the X direction at one end portion in the X direction. The lower end portion of the inclined plate portion 127a overlaps the water collecting port 137 of the water collecting rod 135 when viewed from the vertical direction. Thus, the water that has reached the inclined plate portion 127a can be smoothly flowed to the water collecting port 137.

  The Y direction existence range of the lower drainer 127 includes the Y direction existence range of the plurality of cut and raised portions 171, and the inclined plate portion 127 a of the lower drainer 127 is positioned on the other side in the X direction from the plurality of cut and raised portions 171.

The lower drainer 127 prevents water that travels along the back surface of the cut-and-raised part 171 toward the field plate 5 from reaching the field plate 5 and the water enters the inside of the building via the field plate 5. To prevent.

  The decorative member 130 is provided at an end portion on one side in the X direction of the roof structure 101, and extends in the Y direction from the eave side end portion in the Y direction to the ridge side end portion. As shown in FIG. 6, the decorative member 130 is disposed between the lower drainer 127 and the water guide plate 110 in a region overlapping the base plate 5 when viewed from the Z direction. The decorative member 130 is an integral member, and includes a mounting plate portion 131 and a draining portion 132. The mounting plate portion 131 has a flat plate shape and faces the base plate 5 in the Z direction. The mounting plate portion 131 is attached to the base plate 5 with a fastening member such as a nail, a screw, or a screw, and the draining portion 132 is inclined obliquely downward from one end portion in the X direction of the mounting plate portion 131. The tip is folded inward. The mounting plate portion 131 has recesses 155 that open on both sides in the Z direction and on the other side in the X direction. The existence range of the recess 155 in the Y direction includes the existence direction of the plurality of cut-and-raised parts 171 in the Y direction. Each cut-and-raised part 171 extends into the recess 155 from above the decorative member 130.

  As shown in FIG. 6, the water collecting bowl 135 is located on the inner side of the draining portion 132 that constitutes the side wall portion of the decorative member 130, and is located on the other side in the X direction from the draining portion 132. Further, the lower end of the water collecting bowl 135 is located above the lower end of the decorative member 130. As a result, the water collecting bowl 135 is hidden by the decorative member 130 and is difficult to visually recognize from the outside. The catchment 135 is fixed to the side wall 180 of the building with a known locking structure, for example. Briefly describing this fixing, the water collecting trough 135 has an engaging recess 183 that opens downward at the upper end of the inner wall portion, and an engaging recess 184 that opens downward at the upper end of the outer wall portion. Have A plurality of integral engagement pieces (not shown) are integrally formed with the side wall part 180 and protrude outward from the side wall part 180 at intervals in the Y direction. Each engagement piece has an inner engagement claw portion and an outer engagement claw portion. The inner engagement claw portion of each engagement piece is fitted into the engagement recess 183, and the inner engagement claw portion of each engagement piece is fitted into the engagement recess 184, whereby the water collecting rod 135 is moved to the side wall portion 180. To fix. A basin 159 is connected to the lower side of the water collection basin 135.

  The decorative member 130 is mainly provided in order to make the appearance beautiful in the side view from the one side in the X direction. Furthermore, in the second embodiment, the water collecting bowl 135 is covered with the decorative member 130 and is difficult to visually recognize from the outside. Therefore, also from this reason, the installation of the decorative member 130 provides an excellent aesthetic appearance of the building.

  As described above, as shown in FIGS. 5 and 6, the roof structure 101 includes the decorative member 130 disposed on the side end portion so as to extend from the ridge side to the eaves side, and the side end of the decorative member 130 in the X direction. Is also provided on the inner side, and has a water collecting tub 135 to which a basin 159 is connected. Further, the water guide plate 110 has a cut-and-raised part (water guide part) 171 that guides the water flowing along the ridge part 115 to the water collection port 137 of the water catchment 135.

  Therefore, since the water flowing along the ridge 115 can be directly flowed to the catchment 135, the drainage channel extending in the eaves direction can be omitted in comparison with the first embodiment, and the roof structure 101 can be removed. Can be configured compactly. Further, since the water collecting bowl 135 is disposed on the inner side than the side end of the decorative member 130, the water collecting bowl 135 can be covered with the decorative member 130. Therefore, the building which is excellent in aesthetics can be realized.

  Next, the height of the plurality of protrusions 115 will be described. FIG. 7 is a partial schematic cross-sectional view taken along line BB in FIG. 5 in the assembled roof structure. As shown in FIG. 7, the roof structure 101 includes a plurality of roof materials 187. The roof material 187 is made of, for example, a tile, a steel plate roof material, or the like.

  The water guide plate 110 has a plurality of protrusions 115 arranged at intervals in the Y direction. Each protrusion 115 protrudes in the Z direction, which is the normal direction, from the upper surface 111 located on substantially the same plane in the water guide plate 110. Regarding the plurality of protrusions 115, the height of the protrusions 115 in the Z direction increases as the protrusions 115 are arranged on the eaves side in the Y direction. Further, regarding the plurality of protrusions 115, the height in the vertical direction at the tip of the protrusions 115 becomes lower as the protrusions 115 are arranged on the eaves side in the Y direction.

  FIG. 8 is a schematic cross-sectional view illustrating the level of rainwater flowing along the ridge 115. Referring to FIG. 8, rainwater (snow) that has moved from the ridge side is first dammed to the ridge 115 a that is located closest to the ridge among the plurality of ridges 115 that are not in contact with the roof material 187. It can be stopped. And when the water level of rainwater etc. reaches the upper end of the protrusion 115a shown by L, a part of rainwater will spill to the eaves side.

  In such a background, according to this configuration, with respect to the plurality of protrusions 115, the height of the protrusions 115 in the Z direction increases as the protrusions 115 are arranged on the eaves side in the Y direction. ing. Therefore, the rain water spilled on the eaves side does not pass through the ridge 115b that is one ridge side of the ridge 115a, and is reliably dammed by the ridge 115b.

  That is, the rain water that has fallen from each ridge 115 can be reliably dammed by the ridge 115 on one eave side from the ridge 115. Therefore, since a large amount of rainwater can be stored in the water guide plate 110, a large amount of rainwater can be prevented from flowing into the catchment basin 135 at a stretch, and rainwater can be prevented from spilling from the catchment basin 135.

  Furthermore, with respect to the plurality of protrusions 115, the vertical height at the tip of the protrusion 115 decreases as the protrusion 115 is arranged on the eaves side in the Y direction. Therefore, it can be made inconspicuous that the Z direction height of the protrusion part 115 becomes high as it goes to the eaves side. Therefore, the beauty of the water guide plate 110 can be improved.

  In addition, as shown in FIG. 7, the roof structure 101 includes a plurality of roofing materials 187 a arranged on the ridge side with respect to the water guide plate 110. In addition, the plurality of ridges 115 include a high ridge 115c positioned at the upper side in the Z (normal line) direction with respect to the tangential plane P that is in contact with the plurality of roof materials 187a.

  According to this configuration, rainwater or the like blown off from the roof material 187a to the tangential plane P can be dammed up by the high ridge 115c. Therefore, rainwater can be made to flow into the water collecting tank 135 more reliably.

  As shown in FIG. 7, the roof structure 101 includes a water guide plate-side roof material 187 b that contacts the ridge-side ridge 115 d positioned closest to the ridge among the plurality of ridges 115. More specifically, the eaves side end of the water guide plate side roofing material 187b is supported by the upper part of the ridge side ridge 115d. The water guide plate-side roof material 187b is inclined from the Y direction by the support by the ridge-side protrusion 115d. Further, the water guide plate 110 is located on the back side of the water guide plate-side roof material 187b at a distance from the ridge-side ridge 115d and protrudes upward and extends in the Y direction. It has the water return piece 191 which exists.

  According to this configuration, the water guide plate-side roof material 187b is inclined by the support by the ridge-side protrusion 115d. That is, the eaves side end of the water guide plate side roof material 187b can be lifted upward by the support by the ridge side ridge 115d, and the position of the water guide plate side roof material 187b is indicated by a dotted line from the position shown by a solid line in FIG. It can be moved to the position indicated by. Therefore, the angle θ formed by the water guide plate side roofing material 187b and the roofing material 187 on the one building side than that can be reduced. Therefore, it is possible to suppress rainwater entering the field plate 5 from the gap between the water guide plate side roofing material 187b and the roof material 187 on the one side of the roof, and rainwater enters the inside of the building through the field plate 5. To prevent that.

  In addition, the water guide plate 110 is located on the back side of the water guide plate side roofing material 187b at a distance from the ridge side ridge 115d and protrudes upward and extends in the Y direction. It has the water return piece 191 which exists. Therefore, even if rainwater enters the back side of the water guide plate side roofing material 187b from the gap between the water guide plate side roofing material 187b and the roof material 187 on the one side of the roof, the rainwater is returned to the water return piece. 191 can be dammed up. Therefore, the rainwater can be prevented from reaching the base plate 5, and the rain water can be further reliably prevented from entering the inside of the building via the base plate 5. In addition, when the water return piece 191 extends in the X direction from one end portion in the X direction to the other end portion of the water guide plate 110, it is preferable that rainwater can reach the field plate 5 in a wide area in the X direction. . Also, the eaves roofing material 187c is arranged so as to cover the upper surface of the eaves drainer 125 on the eave side of the ridge 115e located closest to the eaves side, and the eaves side tip portion slightly protrudes toward the eaves side than the eaves drainer 125. May be provided. Thereby, the designability of the eaves is improved.

  Note that the present disclosure is not limited to the above-described embodiment and the modifications thereof, and various improvements and modifications can be made within the matters described in the claims of the present application and the equivalent scope thereof.

  For example, in the first and second embodiments, the case where the water guide plates 10 and 110 include the plurality of protrusions 15 and 115 has been described. However, the water guide plate has only one protrusion extending in the X direction. You may have a section.

  Further, as shown in FIG. 10, that is, a schematic plan view when the water guide plate 110 of the second embodiment is viewed from the upper side in the Z direction, the water guide portion is configured by a cut and raised portion 171 that is inclined obliquely downward. Explained. However, as shown in FIG. 11, that is, a schematic plan view corresponding to FIG. 10 in the modified water guide plate 210, the water guide plate 210 has a plurality of protrusions 215 arranged at intervals in the Y direction. Alternatively, a groove 216 may be provided between the protrusions 215 adjacent in the Y direction. And you may comprise a water conveyance part by the through-hole 271 provided in the X direction one side edge part of the groove part 216. FIG. According to this modification, the water guide part can be easily formed by punching of press molding, and the manufacturing cost of the water guide plate 210 can be reduced.

  Moreover, 1st and 2nd embodiment demonstrated the case where the roof structures 1 and 101 inclined only in the eaves-and-ridge direction. However, the roof structure 1,101 may be inclined in other directions in addition to the eaves-ridge direction. In this case, for example, the eaves may be inclined with respect to the horizontal plane. According to this modified example, in the water guide plate, the protruding portion extends in a direction inclined with respect to the horizontal plane, and the groove portion provided between the adjacent protruding portions is inclined. Therefore, rainwater flows toward the lower side of the groove, and rainwater can be efficiently collected in the catchment. In the case of a square roof, the direction perpendicular to the eave passing through the roof top can be regarded as the eaves ridge direction. In the first and second embodiments, some members necessary for the normal roof structure, such as waterproof sheets, may be omitted, and this does not prevent the addition of these omitted members.
