In addition, a water intrusion suppression member is provided inside the ridge tile that faces the air vent and is spaced from the side wall and fixed to the roof tile, and suppresses the ingress of water from the air vent to the ventilation passage. From entering the attic space through the ventilation passage.

  That is, the ventilation of the ridge can be satisfactorily performed by a simple and inexpensive structure in which a ventilation hole is formed in the side wall of the ridge tile and a water ingress suppression member is provided inside the ridge tile.

  The ventilation structure according to the present invention includes a field plate, a number of roof tiles, a ventilation passage, a ridge tile, a water intrusion suppressing member, a space, a nose bridge, and a face door.

  The field plate is inclined from the ridgeline portion of the tile roof, and a large number of roof tiles are arranged on the field plate. The ventilation passage is partitioned between the uppermost pair of roof tiles facing each other at the ridge line portion of the roof tile and communicates with the attic space. The roof tile has a pair of side walls respectively rising from the top pair of roof tiles and a vent hole formed in at least one of the side walls. Cover from. The water ingress suppression member is fixed to the roof tile facing the ventilation hole inside the ridge tile and spaced from the side wall, and suppresses the entry of water from the ventilation hole to the ventilation passage. The space portion is formed between the roof tile and the base plate along the inclined direction of the tile roof, and communicates with the ventilation passage. The nose bridge is fixed to the edge of the eaves of the field plate, and supports the roof tiles in the lowest direction of the tile roof among the roof tiles from below. The face door is fixed on the outer surface of the nose bridge, and has an upper edge portion along the lower surface of the roof tile in the lowermost row in the inclined direction.

  The nose bridge has an air passage that extends and extends in the tilt direction of the tile roof. The face door has an opening hole that opens the ventilation path and communicates the space between the roof tile and the base plate in the lowermost row in the inclined direction to the outside through the ventilation path.

  Since the ventilation structure having the above configuration has the ridge ventilation structure, the ridge ventilation can be favorably performed with a simple and inexpensive structure as described above.

  The space between the roof tile and the base plate communicates with the ventilation passage at the upper end and communicates with the outside through the ventilation passage of the nose bridge and the opening hole of the face door at the lower end. That is, the space communicates with the outside through the air passage of the nose bridge and the opening hole of the face door without being blocked at the eaves of the tile roof. Therefore, the air permeability between the field board and the roof tile is improved, and the drainage performance when rainwater or the like enters is also improved.

  Furthermore, since the face door has an upper edge portion along the lower surface of the roof tile in the lowermost row in the tilt direction, for example, the lower surface of the roof tile in the lower row in the tilt direction is not a flat surface but between the lower surface of the roof tile and the nose bridge. When a gap is formed on the roof tile, the gap between the roof tile and the nose bridge is closed by a face door. Therefore, it is possible to reliably prevent birds and small animals from entering the gap.

Each roof tile 41 includes a pair of upper walls 42 that extend downward in the left-right direction and a pair of side walls 43 that extend downward from both lower ends of the upper wall 42. The left and right side walls 43 are placed on the topmost roof tile 10 and rise from the pair of roof tiles 10 respectively. The roof tile 41 covers the ventilation passage 45 from above while being arranged on the top roof tile 10. An inner space 46 is defined between the roof tile 41 and the topmost roof tile 10. The ventilation passage 45 is defined between the top roof tiles 10 and communicates the inner space 46 of the ridge tile 41 and the attic space 7.

  The pair of side walls 43 of the roof tile 41 are each formed with a notch-shaped vent hole 47. The water intrusion suppression member 44 has a prismatic shape, and is fixed to the upper surface of the topmost roof tile 10 in the inner space 46 of the ridge tile 41 with an adhesive. The water intrusion suppression member 44 is disposed at a position facing the vent hole 47 so as to be separated from the side wall 43 and suppresses the ingress of water from the vent hole 47 into the ventilation passage 45. In the present embodiment, the ridge tile 41 having the vent holes 47 and the ridge tile 41 not having the vent holes 47 are mixed, but the vent holes 47 may be provided in all the ridge tiles 41. Further, the vent hole 47 may have a through hole shape instead of a notch shape. Further, the vent hole 47 may be formed only on one of the pair of side walls 43. Furthermore, the water ingress suppression member 44 may be set to have an L-shaped cross section, a rectangular cross section, or the like.

  The purlin receiving member 51 includes a purlin accommodation part 52 having a substantially U-shape that opens upward, a leg part 53 that extends downward from the purse accommodation part 52, and a support part 54 that extends left and right from the lower end of the leg part 53. A plurality of them are arranged at predetermined intervals along the depth direction 61 (shown in FIG. 1) of the roof 1. The left and right support portions 54 are placed on the left and right field boards 3 of the ridgeline portion (topmost portion) of the roof 1 and fixed by nails (not shown). The purlin accommodation part 52 is arranged in the inner space 46 with the purlin receiving member 51 fixed in this manner. The purlin 50 has a prismatic shape, and is attached to and supported by the purlin accommodation portion 52.

Therefore, it is possible to prevent rainwater and the like from flowing back and entering the attic space 7 through the ventilation hole 45 through the ventilation hole 47. That is, the ventilation of the ridge can be satisfactorily performed by the simple and inexpensive structure in which the vent hole 47 is formed in the side wall 43 of the ridge tile 41 and the water intrusion suppressing member 44 is provided in the inner space 46 of the ridge tile 41.

  The space 17 between the roof tile 10 and the base plate 3 communicates with the ventilation passage 45 at the upper end thereof, and communicates with the outside through the through hole 12 of the nose bridge 6 and the opening hole 34 of the face door 30 at the lower end thereof. . That is, the space portion 17 communicates with the outside through the through hole 12 of the nose bridge 6 and the opening hole 34 of the face door 30 without being blocked at the eaves of the roof 1. Therefore, the air permeability between the roof tile 10 and the base plate 3 is improved, and the drainage performance when rainwater or the like enters is also improved.

  Note that the roof tile 10 is not directly fixed to the base plate 3 but is also fixed to the tile roof 20 using the roof tile 21 of the type fixed via the tile rail 22 as shown in FIG. The nose bridge 6 is effective. In this case, it is preferable that the tile rail 22 has a communication portion 23 that connects the space portions 17 adjacent to each other in the inclination direction 60 of the roof 1.

  Further, the ventilation path is not limited to the through-hole 12 but extends in the inclination direction 60 of the roof 1 and communicates the space 17 between the bottom row roof tile 10 and the base plate 3 to the outside. If it exists, various shapes and modes can be applied. For example, as shown in FIG. 7, a concave through-groove 14 that forms a gap of a predetermined size with the field plate 3 is formed as a ventilation path on the lower surface of the nose bridge 6 in contact with the field plate 3. An opening hole 35 having a shape corresponding to the through groove 14 may be formed in the face door 30. Moreover, you may comprise the nose bridge 6 by several components. Further, not only the nose bridge 6 having the ventilation path (through hole 12 and through groove 14) is used, but the nose bridge having no ventilation path and the nose bridge 6 having the ventilation path are mixedly arranged (for example, alternately May be arranged). Further, the outer shape of the nose bridge 6 is not limited to a substantially prismatic shape, and various shapes such as a semi-cylindrical shape and a shape having a partially curved surface can be employed.

  In addition, as shown in FIG. 8, the lower surface of the roof tile 10 in the lowermost row in the inclined direction has a curved surface in part or all instead of a flat surface, and there is a gap between the lower surface of the roof tile 10 and the nose bridge 6. Even when 37 is formed, the upper edge 31a of the base 31 of the face door 30 is shaped along the lower surface of the roof tile 10 (providing a protrusion 36 that closes the gap 37 in the base 31). Thus, the gap 37 can be closed and the entry of birds and small animals into the gap 37 can be reliably prevented.

  The present invention can be applied to various tile roof ridge ventilation structures and ventilation structures.
