Yes. Further, one end side of the draining hole 13y is bent upward and a baffle plate 13z is erected. A sealer 13u is attached to the back surface of the other end of the lower frame 13b.

  The first ventilation member 13 abuts the tip of the connecting piece 13d on the upper surface of the rafter 11, and is fixed to the rafter 11 with a nail. In this way, the plurality of first ventilation members 13 are arranged on the back surface of the crown tile 16 and arranged along the longitudinal direction of the ridge.

  As shown in FIG. 8, the second ventilation member 14 includes a main body 14a having a gate-shaped cross section having an opening 14s on the lower end surface, a ventilation cover 14b, a front cover 14c, a rear cover 14d, and a pair of dam plates 14e. As shown in FIG. 9, fourth vents 14f are formed at a plurality of locations on both side surfaces of the main body 14a, and water return 14g protruding outside the main body 14a is formed at the lower end of each vent 14f. . A leg piece 14h is integrally provided at a lower end portion of the main body 14a and is spread on both sides of the main body 14a. The ventilation cover 14b has fifth ventilation holes 14i formed at a plurality of locations along the longitudinal direction. Downward bent pieces 14j are formed at both ends of the ventilation cover 14b. The upper end of the weir plate 14e is bent outward, and the sixth vent 14k is formed at the lower part.

  The second ventilation member 14 is covered with a ventilation cover 14b on the upper surface of the main body 14a and fixed to the main body 14a with rivets (not shown), and a front cover 14c and a rear cover 14d are respectively attached to the front end portion and the rear end portion of the fixed ventilation cover 14b. Are assembled and assembled. As will be described later, when the second ventilation member 14 is installed in the ridge, the dam plate 14e is installed so as to lean against the lower bent piece 14i of the ventilation cover 14b.

The structure of the 1st ventilation member 13 and the 2nd ventilation member 14 which comprises the ventilation member 10 for buildings is as above, Comprising: A construction method is demonstrated below.
The lower end surface opening 14s of the second ventilation member 14a is put on the building ventilation port 17, and the leg piece 14h is brought into contact with the field 15 and fixed to the field 15 with a nail. The weir plate 14e is leaned on both sides of the main body 14a, and the uppermost flat roof tile 19 of the ridge is hooked on the roof tile 18. Stucco 20 is filled in the space defined by the bottom of the dam plate 14e and the flat roof tile 19.

  The support fitting 12 is fixed to the field 15, and the rafter 11 is fixed to the support fitting 12. The connecting piece 13 d of the first ventilation member 13 is brought into contact with the rafter 11 and fixed with a nail, and the sealer 13 u is pressed against the upper surface of the bottom of the flat roof tile 19. Then, the roof tiles 16 are placed on the rafters 11 and the left and right first ventilation members 13, the crown roof tiles 16 are placed on the support members 13 m of the rafters 11 and the first ventilation members 13, and fixed to the rafters 11 with nails.

  According to the building ventilation member 10 according to the present embodiment, as shown in FIG. 10, the main ventilation passage S <b> 1 that communicates the back of the hut and the outside is the lower end surface of the main body 14 a of the second ventilation member 14 in order from the building ventilation port 17. The opening 14s, the internal space of the main body 14a, the fourth vent 14f, the fifth vent 14i, the first vent 13f of the first ventilation member 13, the internal space of the first ventilation member 13, the second vent 13g and the third It is formed by the flow of air through the vent 13n.

  In addition, the first sub-ventilation passage S2 extending from the one side of the ridge across the rafter 11 to the other side of the roof tile 16 on the back side of the crown tile is the second vent 13g in order from the third vent 13n of the one first arousing member 13. The internal space of one first ventilation member 13, the first ventilation port 13f, the transverse ventilation passage 11a, the first ventilation port 13f of the other first ventilation member 13, the internal space of the other first ventilation port 13, the second ventilation It is formed by the flow of air passing through the opening 13g and the third ventilation hole 13n of the other first ventilation member 13.

  Furthermore, the second auxiliary ventilation passage S3 that communicates the space between the flat roof tile 16 and the field 15 and the outside is in order from the sixth ventilation port 14k of the dam plate 14e, and the main body 14a of the second wake member 14a. This is formed by the flow of air passing through the space defined by the side surfaces, the fifth ventilation port 14i, the first ventilation port 13f, the internal space of the first ventilation member 13, the second ventilation port 13g, and the third ventilation port 13n.

  According to the present embodiment, when the wind blows outdoors, the outdoor air flows from one side of the building to the other side through the first auxiliary ventilation passage S2, so the air in the back of the cabin flows through the first auxiliary ventilation passage S2. It gets caught in the wind and flows out. Therefore, it is possible to secure a sufficient air flow rate for ventilating the back of the hut.

  Since the drain hole 13y is formed on the bottom surface of the first ventilation member 13, rainwater that has entered the first ventilation member 13 can be discharged onto the flat roof tile 19 from the drain hole 13y. Further, since the baffle plate 13z is erected at the one end side end portion of the draining hole 13y, it is possible to prevent a large amount of rainwater from entering the first ventilation member 13 from the draining hole 13y.

  The second sub-air passage S3 allows ventilation on the back space of the flat roof tile 19, that is, on the field 15. On the other hand, rainwater enters the body 14a of the second ventilation member 14 from the fourth ventilation port 14f through the field 15 by the air flow passing through the second auxiliary ventilation passage S3, and the lower end of the fourth ventilation port 14f. It can be blocked with 14 g of water return provided in
