  By the way, in the eaves edge (eave edge of the baseboard) at the bottom of the roof, the direction in which the roof nose bridges that support the roof tiles in the bottom row (eave edge) from the bottom cross the roof inclination Are arranged and fixed in a substantially straight line. However, the conventional nose bridge is made of wooden timber, and there is not enough space between the nose bridge and the field board. Therefore, the slope of the roof is between the field board and the roof tile. Even if the space part along the line is secured, the space part is blocked by the nose bridge at the eaves of the roof. For this reason, sufficient ventilation cannot be obtained between the field board and the roof tile, and when the tile roof becomes high temperature due to an increase in temperature, the temperature of the air significantly increases in the space portion, The effect is greatly related to the room temperature. In addition, drainage when rainwater or the like enters is poor.

  Accordingly, an object of the present invention is to provide a ventilation structure for a nose bridge and a tile roof capable of improving the air permeability and drainage of the tile roof.

  In order to solve the above-mentioned problem, the nose bridge according to the present invention is fixed to the eaves edge of the field board, and supports the roof tiles in the lowest row in the inclination direction of the roof among the many roof tiles arranged on the field board from below. It has an air passage that extends in the inclination direction of the roof and communicates the space between the lowermost roof tile and the base plate to the outside.

  In addition, the tile roof ventilation structure according to the present invention is formed between a roof plate, a large number of roof tiles disposed on the roof plate, and the roof tile and the roof plate, and communicates along the inclination direction of the roof. A tile roof ventilation structure comprising a space and a nose bridge fixed to the eaves edge of the field board and supporting the roof tiles in the bottom row of the roof in the direction of inclination of the roof. And a ventilation passage that communicates with the outside the space between the roof tile in the bottom row and the base plate.

  In the above configuration, the space between the lowermost roof tile and the base plate communicates with the outside through the air passage of the nose bridge. That is, the space part formed between the field board and the roof tile and communicated along the inclination direction of the roof communicates with the outside through the air passage of the nose bridge without being blocked at the eaves of the 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.

  According to the present invention, it is possible to improve the air permeability and drainage of the tile roof.

  Hereinafter, an embodiment of a ventilation structure for a tiled roof according to the present invention will be described with reference to the drawings. 1 is a cross-sectional view of the main part of the tile roof of the present embodiment, FIG. 2 is a perspective view of the nose bridge of FIG. 1, FIG. 3 is a perspective view showing a state in which the nose bridge of FIG. It is sectional drawing which shows typically the state of the ridge ventilation of the tile roof of FIG.

  As shown in FIG. 1, a tiled roof (hereinafter simply referred to as a roof) 1 includes a field board 3 fixed on the talc 2 and a number of roof tiles 10 arranged on the field board 3. The field board 3 includes a wooden plywood 4 and a water-resistant sheet material 5 laid on the plywood 4.

  As shown in FIG. 1 to FIG. 3, a plurality of nose bridges 6 are substantially straight on the top surface of the eaves edge of the field board 3 (the eaves at the lowest part of the roof 1) substantially orthogonal to the inclination direction of the roof. Arranged side by side, each nose bridge 6 is fixed to the base plate 3 by a nail 7. In addition, an eaves 16 is provided in the vicinity of the lower side of the nose bridge 6.

  On the nose bridge 6, the lower end (eave end side) of the roof tile 10 in the lowermost row (eave side tip) in the inclination direction 40 of the roof 1 is placed. It is fixed. Further, the upper end portion (ridge side) of the roof tile 10 in the lowermost row is fixed to the field plate 3 with nails 9. The lower end of the roof tile 10 in the lowermost row is overlaid with the lower end of the roof tile 10 just above the inclination direction 40 of the roof 1 (second row upward from the lowermost row). Is also fixed to the base plate 3 by a nail 9. In this way, the roof tiles 10 are sequentially stacked from the bottom row and fixed to the field board 3. Thereby, a space portion 17 is formed between each roof tile 10 and the field board 3.

  The upper end portion of each roof tile 10 bends downward and comes into contact with the base plate 3, but a concave portion 11 that forms a gap with the base plate 3 is partially formed on the lower surface of the upper end portion. . By this recess 11, the space portions 17 adjacent in the inclination direction 40 of the roof 1 communicate with each other. That is, a space portion 17 that communicates along the inclination direction 40 of the roof 1 is ensured between the roof tile 10 and the field board 3.

  Each nose bridge 6 has a substantially prismatic shape, and is formed of wood, a resin material, or the like. A plurality of through-holes 12 are formed in the nose bridge 6 as ventilation paths that extend along the inclination direction of the roof 1 and penetrate the width direction of the nose bridge 6. With the through hole 12, the space 17 between the lowermost roof tile 10 and the base plate 3 communicates with the outside. In addition, although the through-hole 12 can also be formed by post-processing using a drill etc., it is more preferable to form beforehand by injection molding with a resin material.

  As shown in FIG. 4, the lower part of the attic space 33 defined below the roof 1 communicates with the outside through a ventilation port 31 formed of a perforated plate, a metal mesh, or the like, and the upper part is provided on the top of the roof 1. The building ventilation device 32 communicates with the outside. Further, the upper end of the space 17 that communicates along the inclination direction 40 of the roof 1 is also communicated with the outside by the building ventilation device 32.

  According to the present embodiment, the space portion 17 between the roof tile 10 in the lowermost row and the base plate 3 communicates with the outside through the through hole 12 of the nose bridge 6. That is, the space portion 17 formed between the field board 3 and the roof tile 10 and communicating along the inclination direction 40 of the roof 1 is not blocked by the eaves of the roof 1 by the through hole 12 of the nose bridge 6. Communicate with the outside. Therefore, for example, when the roof 1 becomes hot due to a rise in temperature and the air in the space portion 17 is heated and moves upward, the outside air flows into the space portion 17 from the communication hole 12 of the nose bridge 6, and the space The inside of the part 17 flows well upward and flows out from the building ventilation device 32. Further, when the flow of air flowing into the attic space 33 from the ventilation port 31 and flowing out from the building ventilator 32 due to the temperature rise in the attic space 33 (indicated by the arrow 41 in the figure) increases, In 32, the flow of the air of the building ventilation concerned draws the air of the space part 17, and the quantity of the air which distribute | circulates the inside of the space part 17 also increases.

  Thus, in this embodiment, since the space part 17 formed between the field board 3 and the roof tile 10 and communicating along the inclined direction 40 of the roof 1 communicates with the outside at the upper and lower ends, The air flow (indicated by the arrow 42 in the figure) between the main plate 3 and the roof tile 10 becomes good, and the air permeability is improved. Therefore, the temperature rise of the space part 17 accompanying the temperature rise of the roof 1 can be efficiently suppressed, and the influence of the temperature rise of the roof 1 on the room temperature can be mitigated.

  Even if rainwater or the like enters the space 17 between the field plate 3 and the roof tile 10, the rainwater or the like is drained from the through hole 12 to the outside. Therefore, an increase in the humidity of the space portion 17 can be suppressed, and the influence of moisture or the like can be mitigated.

  The air passage is not limited to the through hole 12 but extends in the inclination direction 40 of the roof 1 and communicates the space 17 between the bottom roof tile 10 and the field board 3 to the outside. If it exists, various shapes and modes can be applied. For example, as shown in FIG. 5, 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 13 in contact with the field plate 3. Also good. Further, the nose bridges 6 and 13 may be constituted by a plurality of parts.

  Further, only the nose bridge 6 having the ventilation path (through hole 12) is used, and the nose bridge 15 having no ventilation path and the nose bridge 6 having the ventilation path are mixedly arranged as shown in FIG. (For example, they may be arranged alternately.)

  Furthermore, the upper end of the roof tile 10 is not directly fixed to the base plate 3, but the tile roof 20 using the roof tile 21 of the type fixed through 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 40 of the roof 1.

  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 or a shape having a partially curved surface can be employed.

  The present invention can be applied to various nasal bridges and tiled roof ventilation structures.
