Forming. On the other hand, the aeration space 21 is defined by the connection portion 14b of the dam portion 14a, the bottom half 19a of the flat roof tile 19, and the field 15 by preventing the filler from entering the dam portion 14a.

  The structure of the rafter 11, the rafter support fitting 12, the first ventilation member 13, and the second ventilation member 14 is as described above. As shown in FIG. 7, the ridge ventilation port 17 → the leg portion 14c of the second ventilation member 14 as shown in FIG. → The ventilation space 21 defined by the connecting portion 14b of the dam portion 14a and the lower half of the bottom edge portion 19a of the flat roof tile 19 and the field 15 → the opening 14k of the bottom surface 14h of the dam portion 14a of the second ventilation member 14 → The channel section defined by the outer standing piece 14f and the inner standing piece 14g of the second ventilation member 14 → the first ventilation port 13f of the first ventilation member 13 → the internal space of the first ventilation member 13 → the first ventilation member 13 The main ventilation passage 22 that connects the back of the cabin and the outside is formed by the second ventilation hole 13g → the third ventilation hole 13n of the first ventilation member 13.

  The third ventilation port 13n of the first ventilation member 13 → the second ventilation port 13g → the internal space of the first ventilation member 13 → the first ventilation port 13f of the first ventilation member 13 → the cross ventilation passage 11a of the rafter 11 is crowned. A first sub vent passage 23 is formed on the back side of the roof tile 16 so as to straddle the rafter 11 and communicate from one side of the building to the other side.

  Furthermore, the space behind the uppermost flat roof tile 19 (the gap between the uppermost flat roof tile 19 and the field 15) → the connecting portion 14b of the weir 14a and the lower half of the bottom edge 19a of the uppermost flat roof tile 19 The ventilation space 21 partitioned by the field 15 → the channel portion of the weir 14a → the first ventilation port 13f of the first ventilation member 13 → the internal space of the first ventilation member 13 → the second ventilation port 13g of the first ventilation member 13 → A second sub-ventilation passage 24 that connects the field 15 and the outside is formed by the third vent 13n of the first ventilation member 13.

  According to the building ventilation structure 10 according to the present embodiment, when the wind blows outdoors, the outdoor air flows from the one side of the building to the other side through the first sub-ventilation passage 23. It is caught in the wind flowing through the first sub-air passage 23 and flows out through the main air passage 22. Therefore, it is possible to secure a sufficient air flow rate for ventilating the back of the hut.

  Further, the second auxiliary ventilation passage that communicates the back space of the uppermost flat roof tile 19 and the second ventilation member 14 by damming the filler 20 at the bottom edge 19a of the uppermost flat roof tile 19 with the weir 14a. Since 24 is formed, ventilation on the back side space of the flat roof tile 19, that is, the field 15 is possible through the second auxiliary ventilation passage 24.

Further, since the drainage groove 13q is formed in the first ventilation member 13, rainwater that has entered the inside of the first ventilation member 13 can be discharged onto the flat roof tile 19 from the drainage groove 13q.
Furthermore, since the outer opening end face of the water draining groove 13q is covered with a water stop piece 13h with a gap, rainwater that has entered the inside of the first ventilation member 13 can be discharged onto the flat roof tile 19 from the gap, It is possible to prevent a large amount of rainwater from entering the drain groove 13q.

  In the present embodiment, the filler 20 is dammed by the outer standing piece 14f constituting the dam portion 14a of the second ventilation member 14, but when an S-shaped roof tile is provided between the crown roof tile 16 and the flat roof tile 19, Alternatively, when the height from the flat roof tile 19 to the crown roof tile 16 is increased as in the case of stacking roof tiles, as shown by a two-dot chain line in FIG. 7, a dam plate 25 is provided along the outer upright piece 14f. Thus, the filler can be dammed up.

  FIG. 8 shows another embodiment of the rafter 11 in this embodiment. The rafter 11 described above is formed by cutting the transverse ventilation passage 11a. However, as shown in FIG. 8, the sheet metal member 26 formed in a U-shape is fixed to the rafter 11 to form the transverse ventilation passage 26a. Alternatively, the transverse ventilation passage 27a can be formed by fixing the ventilation member 27 made of plastic resin.

9 to 11 show another embodiment of the first ventilation member 13 in this embodiment. In the first ventilation member 13 described above, as shown in FIG. 5, a vertical frame 13p made of plastic and having a square cross section is fixed inside the water stop piece 13h of the upper frame 13a, but the first ventilation member shown in FIG. In 13A, the vertical frame 13q is omitted. On the other hand, as shown in FIG. 11, a bent piece 13w is formed at one end of the lower frame 13b so as to overlap the water stop piece 13h of the upper frame 13a when the upper frame 13a and the lower frame 13b are combined. A drain hole 13y is formed from the base end of the bent piece 13w to the bottom surface of the lower frame 13b.
