JP2010-248817A

  By the way, in the case of a win-win roof structure as shown in Patent Document 1, when the eaves are installed, the eaves is made difficult to come into contact with the gust of wind. For this reason, it is preferable that the eaves rod is disposed away from the projecting portion of the breezes in the direction along the eave, thereby forming a gap between the end portion on the blast side of the eaves ridge and the projecting portion of the gust wind. However, if a gap is formed between the eaves wall and the breezes in this way, there is a concern that rainwater that has flowed down from the end of the roof surface on the side of the eave to the eaves side will fall down the eaves through the gap.

  The present invention has been made in view of the above circumstances, and can easily construct eaves eaves and make it difficult for rainwater that has flowed down from the end of the roof side to the eaves side to fall under the eaves. It is an object to provide a roof structure that can be used.

  In order to solve the above-mentioned problem, the roof structure of the present invention includes a rib member provided at an end portion of a roof side of the roof, and an eave fence provided on the eave side of the roof, and the rib member includes The rib member of the eave ridge has a protruding portion protruding toward the eave side from the roof surface constituting the upper surface of the roof, and the eave ridge is disposed apart from the protruding portion in a direction along the eave. A gap is formed between the end portion on the side and the protruding portion, and further includes a water guide member that guides rainwater that has flowed down from the end on the wife side of the roof surface to the eaves side, the water guide member, A water receiving portion that is located on the upper side of the gap and receives rain water that has flowed down from the roof surface to the eaves side, and protrudes from the water receiving portion in an oblique direction on the opposite side to the lower side and on the lower side. The projecting end has a water guide portion disposed on the upper side of the eaves bowl.

  Moreover, it is preferable that the said water guide member is attached to the said loose member.

  Further, the roof surface is composed of an uneven roof material in which convex portions opening downward and projecting upward and concave portions opening upward and recessed downward are formed in a direction along the eaves, and the water receiving portion is It is preferable to arrange at a position corresponding to the recess in the direction along the eaves.

  In this invention, since a clearance gap is formed between the edge part of the eaves rib side member side, and the protrusion part of the eaves member, the construction which attaches an eaves wall to a roof can be made easy. In addition, rainwater that has flowed down from the end of the wife side of the roof surface to the eaves side is received by the water receiving part of the water guide member, and this rain water is allowed to flow on the water guide part and fall from the protruding end of the water guide part to the eaves bowl. it can. For this reason, it is difficult for rainwater that has flowed down from the roof surface to the eaves side to fall under the eaves via the gap between the protrusions of the members and the eaves fence. In addition, rainwater that reaches the projecting end of the water guide portion is projected to the lower surface side of the water guide portion by projecting the water guide portion from the water receiving portion toward the diagonal direction that is opposite to the member and on the lower side. It becomes difficult to wrap around. Therefore, the rain water on the water guide portion can be appropriately dropped from the protruding end of the water guide portion, and this rain water can be received by the eaves.

It is a perspective view which shows the roof structure of embodiment of this invention. It is AA 'sectional drawing of FIG. Fig. 2 shows the same loose member and a water guide member attached thereto, in which (a) is a front view and (b) is a side view.

The fixed plate portion 120 is placed on the placement piece portion 110 in a state where the lower surface is along the upper surface on the placement piece portion 110 of the eaves edge drainer 11. The fixed plate portion 120 of each face door 12 and the placing piece portion 110 of each eaves tip drainer 11 are attached to the field plate 100 by a fastener such as a screw or a nail.

  The fixed plate portion 120 of each face door 12 protrudes to the eaves side from the field plate 100. In this portion, a plurality of blocking plate portions 121 are provided with an interval in the eave direction. Each blocking plate portion 121 rises from the fixed plate portion 120. Each closing plate part 121 is formed by cutting and raising a part of the fixed plate part 120. A vent hole 123 formed by the cut and raised portion is provided in a portion of the fixed plate portion 120 that is closer to the ridge than the portion where the blocking plate portion 121 is raised.

  The fixed plate portion 120 of each face door 12 has a portion 122 that protrudes toward the eaves side from the place where the blocking plate portion 121 is raised. The portion 122 of each face door 12 is located above the hanging piece 113 of the eaves edge drainer 11. As for the part 122 of each face door 12, the eaves side part inclines with a steep slope compared with the ridge side part. The eaves-side end portion (the eave-side end portion of the fixed plate portion 120) of the portion 122 of each face door 12 is located on the eave side with respect to the hanging piece portion 113 of the eaves tip drainer 11.

  A plurality of the roofing materials 13 are provided side by side in the eave direction on the roof base 10. Each roof material 13 is placed on the base plate 100 via a placement piece 110 of the eaves edge drainer 11 and a fixed plate part 120 of the face door 12.

  The roof material 13 of the present embodiment is an uneven roof material, and as shown in FIG. 1, convex portions 130 that open downward and protrude upward, and concave portions 131 that open upward and dent downward alternate in the eave direction. Is formed. The roof surface which is the upper surface of the roof 1 is constituted by these roof materials 13. Adjacent roofing materials 13 are connected to each other via a connecting tool (not shown) fixed to the base plate 100. Each roof material 13 is arranged so that the convex portion 130 faces the closing plate portion 121 of the face door 12 and the concave portion 131 is positioned between the adjacent closing plate portions 121.

  As shown in FIG. 2, a ventilation space 132 communicating with the eaves side and the ridge side is formed between each convex portion 130 of each roofing material 13 and the base plate 100.

  The eaves-side end portion of each roofing material 13 protrudes toward the eave side from the field plate 100, and the protruding end surface is in contact with the corresponding blocking plate portion 121 of the face door 12. Thereby, the eaves side edge part of each convex part 130 of the roofing material 13 is obstruct | occluded by the corresponding obstruction | occlusion board part 121. FIG.

  The portion 122 of the fixed plate portion 120 of each face door 12 is located on the eaves side with respect to the roof material 13. That is, the portion 122 of the fixed plate portion 120 of the face door 12 is an extended portion of the roof surface made of the roof material 13 toward the eaves side. The rainwater flowing from the ridge side toward the eaves side along the upper surface of the roofing material 13 flows on the portion 122 protruding from the roofing material 13 toward the eaves side in the fixed plate portion 120 of the face door 12, and then the fixed plate portion 120. It comes to fall from the end of the eaves side.

  The eaves side end of each convex portion 130 of each roofing material 13 opens downward through the vent hole 123 of the corresponding face door 12. Thereby, the ventilation space 132 formed on the lower surface side of each roof material 13 communicates with the eaves side through the ventilation holes 123. The projecting piece 112 and the hanging piece 113 of each eaves tip drainer 11 serve to prevent rainwater from blowing into the vent hole 123.

  FIG. 3 shows the loose member 2. As shown in FIG. 1, the rib member 2 of the present embodiment is a cover that wraps around the end of the roof 1 on the wife side, and is attached to the end (kerak) of the roof 1 on the wife side. ing.

  The edge part of the eaves side of the slab member 2 protrudes from the roof material 13 to the eaves side. That is, this embodiment has a so-called win-win roof structure in which the rib member 2 protrudes toward the eaves side from the roof surface.

  In the loose member 2, a groove portion 21 (see FIG. 3) that is long in the eaves direction and opens to the roof 1 side (opposite side of the wife) is formed. The groove portion 21 is formed from the ridge side end portion of the rib member 2 to a portion projecting to the eaves side from the nose plate 14 as shown in FIGS. 1 and 2.

  As shown in FIG. 1, in the groove portion 21, there is an end on the wife side of the base plate 100, a windbreak plate (not shown) provided on the end on the end side of the roof 1, and an end on the wife side of the nose plate 14. The parts are accommodated, and these are covered with the members 2. In the present embodiment, a recess 131 is formed at the end of the roof 13 located on the most end side, and the end of the recess 131 is accommodated in the groove 21.

  An end portion of the groove portion 21 located on the eaves side with respect to the nose plate 14 is a narrow portion 210 having a groove width smaller than that of other portions. The narrow portion 210 extends from the upper end of the groove 21 on the ridge side to the eaves side. The eaves-side end of the narrow part 210 is located closer to the ridge than the eaves-side end of the member 2, and the narrow part 210 is not open to the eaves side. The narrow portion 210 accommodates the end portions of the base plate 100, the roof material 13, the eaves drainer 11, and the face door 12.

  The eaves bowl 3 is composed of an eaves bowl body 30 and an eaves bowl stop 31. The eaves main body 30 is formed in a groove shape that is long and open upward in the eave direction. Although illustration is omitted, the eaves rod main body 30 is supported by a plurality of eaves rod suspensions attached to the nose plate 14 in the eave direction.

  The eaves main body 30 is located below the eaves-side end of the fixed plate portion 120 of each face door 12 and below the lower end of the hanging piece 113 of each eaves tip drainer 11. For this reason, rainwater that has fallen from the eaves-side end of the fixed plate portion 120 through the fixed plate portion 120 of the face door 12 from the upper surface of the roofing material 13 is received by the eaves main body 30. Further, the eaves main body 30 is located below the lower end of the hanging piece 113 of each eaves tip drainer 11. For this reason, rainwater that has dropped from the lower end of the hanging piece 113 is also received by the eaves main body 30.

  The eaves stop 31 is attached to the end of the eaves main body 30 on the wife side. The end opening on the wife side of the eaves main body 30 is closed by an eaves stop 31.

  An eaves anchor 31 that constitutes the end face of the eaves eaves 3 faces the protruding portion 20 that protrudes toward the eaves side of the roof material 13 in the rib member 2. The eaves stop 31 is spaced apart from the protrusion 20 of the member 2 in the eave direction. As a result, a gap 5 is formed between the eaves guard 31 and the protrusion 20. By forming such a gap 5, when attaching the eave ridge 3 to the roof 1, it becomes difficult to contact the member 2 if the eave ridge 3 is loose, and the construction is facilitated. The gap 5 also serves to prevent the eaves rod 3 from contacting the loose member 2 when the eaves rod 3 is thermally expanded.

  A water guide member 4 is attached to a portion of the slab member 2 that protrudes toward the eaves side from the nose plate 14. The water guide member 4 causes rainwater that has flowed down to the eaves side from the end of the roof surface on the wife side (that is, the recessed portion 131 formed at the end of the roof 13 located on the most wife side). Lead to.

  As shown in FIG. 4, the water guide member 4 is made of a steel plate, and includes a water receiving piece 40, a first attachment piece 41, a second attachment piece 42, a water return piece 43, and a water guide piece 44.

  The water receiving piece 40 constitutes a water receiving portion that receives rainwater that has flowed down from the end on the roof side to the eaves side. The water receiving piece 40 includes a ridge side portion 400, a water collection portion 401, and an eave side portion 402, which are arranged in order from the ridge side to the eaves side.

  As shown in FIG. 2, the ridge side portion 400 is disposed below the protruding piece portion 112 of the eaves edge drainer 11. The ridge side portion 400 is inclined so as to be positioned downward as it goes to the eaves side, and is substantially parallel to the field board 100. At the ridge side end of the ridge side 400, a water return piece 43 is formed by folding the ridge side end of the ridge side 400 upward to the eave side.

  The water collection part 401 protrudes substantially horizontally from the ridge side part 400 toward the eaves side. The water collecting portion 401 protrudes toward the eaves side from the hanging piece portion 113 of the eaves tip drainer 11.

  The eaves side portion 402 protrudes from the eave side end of the water collecting portion 401 in an oblique direction on the eave side and on the upper side. That is, the eaves side portion 402 is inclined so as to be positioned downward as it goes to the ridge side. The eaves side portion 402 is located on the eave side of the end portion on the eave side of the fixed plate portion 120 of the face door 12 and faces the end portion on the eave side of the fixed plate portion 120.

  A first attachment piece 41 that protrudes upward is formed at the wife side edge of the ridge side portion 400. A second attachment piece 42 that protrudes toward the ridge is formed on the end of the eaves side 402 on the wife side.

  The first attachment piece 41 and the second attachment piece 42 are separated by a fixing tool such as a screw in a state along the groove depth of the narrow portion 210 (end portion on the eaves side of the groove portion 21) of the rib member 2. It is attached to the member 2. That is, the attachment portion of the water guide member 4 to the loose member 2 is constituted by the first attachment piece 41 and the second attachment piece 42.

  As shown in FIG. 1, the water receiving piece 40 protrudes from the side surface of the rib member 2 on the side of the eaves 3 (opposite side of the wife) toward the eaves 3. The protruding portion of the water receiving piece 40 is disposed above the gap 5 between the eaves-trap stop 31 and the protruding portion 20.

  Rainwater that has flowed to the eaves side through the fixed plate portion 120 of the face door 12 from the recess 131 formed at the end of the end of the roof 13 located on the side of the wife seems to be received by the water receiving piece 40. It has become. In this way, the rainwater received by the water receiving piece 40 is collected on the water collecting portion 401 by the inclined ridge side portion 400 and the eaves side portion 402. When rainwater flows on the ridge side 400 toward the ridge side, the rainwater is returned to the water collection unit 401 side by the water return piece 43.

  The water guide piece 44 protrudes from the edge of the water collecting portion 401 of the water receiving piece 40 on the eaves bowl 3 side (opposite side of the wife) in an oblique direction on the eaves bowl 3 side and the lower side. The water guide piece 44 extends over the entire length of the edge of the water collecting portion 401 on the eaves side. The protruding end of the water guide piece 44 is a free end and is located above the eaves main body 30.

  As described above, the rainwater collected on the water collection portion 401 of the water receiving piece 40 after falling from the end of the roof surface on the wife side to the eaves side flows into the water guide piece 44. And this rain water flows to the eaves 3 side along the upper surface of the water guide piece 44 inclined downward toward the eaves 3 side, and then falls from the projecting end of the water guide piece 44 and is received by the eaves 3. It is like that. That is, the water guide piece 44 constitutes a water guide portion that guides rainwater received by the water receiving piece 40 to the eaves 3.

  The roof structure of the present embodiment described above includes the rib member 2 provided at the end of the roof 1 on the wife side and the eaves fence 3 provided on the eaves side of the roof 1. In addition, the rib member 2 has a protruding portion 20 that protrudes toward the eaves side from the roof surface (roof material 13) that constitutes the upper surface of the roof 1, and the eaves rod 3 is disposed away from the protruding portion 20 in the eave direction. Thus, a gap 5 is formed between the end of the eaves bowl 3 on the side of the loose member 2 and the protrusion 20. For this reason, the construction which attaches the eaves wall 3 to the roof 1 can be made easy.

  Moreover, the water guide member 4 which guides the rainwater which fell from the edge part of the wife side of a roof surface to the eaves side is further provided. And the water guide member 4 is located above the gap 5 and receives the rain water 40 (water receiving portion) that receives the rainwater that has flowed down from the roof surface to the eaves side, and the side opposite the member 2 from the water receiving piece 40. In addition, it has a water guide piece 44 (water guide part) that protrudes in an oblique direction on the lower side and whose protruding end is arranged on the upper side of the eaves cage 3. For this reason, the rainwater that has flowed down from the end on the wife side of the roof surface to the eaves side is received by the water receiving piece 40 of the water guide member 4, and then flows onto the water guide piece 44 and from the protruding end of the water guide piece 44. It will fall to the eaves 3. Therefore, it is difficult for rainwater that has flowed down from the end of the roof surface on the wife side to the eaves side to fall under the eaves via the gap 5 between the protruding portion 20 of the member 2 and the eaves rod 3. Further, since the water guide piece 44 protrudes from the water receiving piece 40 in an oblique direction opposite to the member 2 and on the lower side, rainwater reaching the projecting end of the water guide piece 44 is transferred to the water guide piece 44. It becomes difficult to go around to the lower surface side of the water and easily falls from the protruding end of the water guide piece 44. For this reason, rainwater that reaches the protruding end of the water guide piece 44 can be appropriately received by the eaves rod 3.

  Moreover, in this embodiment, the rainwater which flowed down from the edge part of the wives side of a roof surface to the eaves side can be guide | induced to the eaves eaves 3 by the water guide member 4 attached to the loose member 2. FIG.

  Moreover, the roofing material 13 of this embodiment is comprised by the uneven | corrugated roofing material by which the convex part 130 which opens below and protrudes upwards, and the recessed part 131 which opens upwards and is dented below are formed in the direction along an eave alternately. ing. And the water receiving piece 40 of the water guide member 4 is arrange | positioned in the position corresponding to the recessed part 131 in the eaves direction. For this reason, when rainwater that has flowed into the recess 131 provided at the end of the end of the roof material 13 falls to the eaves side, the rainwater can be guided to the eaves cage 3 by the water guide member 4.

  In this embodiment, the water guide member 4 is attached to the loose member 2, but the water guide member 4 can be attached to a member other than the loose member 2, such as the roofing material 13, the nose plate 14, the eaves 3 and the like. There may be. Moreover, in this embodiment, the recessed part 131 of the roofing material 13 was arrange | positioned in the edge part by the side of a wife, and the water receiving piece 40 of the water guide member 4 was arrange | positioned in the position corresponding to this recessed part 131. However, the convex portion 130 of the roofing material 13 may be arranged at the end on the side of the wife, and the water receiving piece 40 of the water guiding member 4 may be arranged at a position corresponding to the convex portion 131. The roof material 13 is not limited to the uneven roof material, and may be a roof material other than the uneven roof material such as a slate. Further, in the present embodiment, the member 2 is a cover that covers the end of the end of the roof 1 but may be a windbreak plate or the like provided at the end of the end of the roof 1.
