  FIG. 5A is a perspective view showing a state in which the water return plate 30 is installed in the roof ridge. In FIG. 5A, the roof 40 is partially shown. The water return plate 30 is divided into one water return plate element body 31 and the other water return plate element body 32 at the end face portion 30 b of the water return plate 30. In addition, the water return plate bodies 31 and 32 are vertically provided at the vertical pieces 31a and 32a provided upright along the longitudinal direction of the ridge so as to surround the opening 40a, and at both ends in the longitudinal direction of the vertical pieces 31a and 32a. End pieces 31b and 32b provided so as to be orthogonal to the pieces 31a and 32a, and inclined pieces 31c and 32c provided so as to be inclined to the side of the water return plate 30 at the lower side which is the roof side of the vertical pieces 31a and 32a. With. Here, a substantially rectangular vent 30a is formed by the vertical pieces 31a and 32a and the end pieces 31b and 32b. In addition, water return pieces 31d and 32d are bent and provided on the upper sides of the vertical pieces 31a and 32a. The water return pieces 31d and 32d are not essential and need not be provided.

  Next, a means for joining the water return plate element 31 and the water return plate element 32 will be described. FIG. 5B is a view showing a coupling mechanism 34 by rivets 33 as coupling means. The rivet coupling mechanism 34 is configured such that the rivet insertion hole 31e of the end piece 31b of the water return plate element 31 and the insertion hole 32e of the end piece 32b of the water return plate element 32 communicate with each other. The end piece 31b and the end piece 32b are joined by overlapping the b 32b, inserting the rivet 33 through the insertion hole 31e and the insertion hole 32e, and expanding the opposite side 33b of the head 33a of the rivet 33.

  The pair of coupling mechanisms 34 by the rivets 33 serving as the coupling means are configured so that the longitudinal axis of the ridge is parallel to the longitudinal direction of the ridge at both ends of the water return plate 30 so that the rotation axis L that is the central axis of the rivet 33 is parallel to the longitudinal direction of the ridge. It is provided at a plane-symmetrical position with respect to a plane perpendicular to the direction. The rivet 33 may be a normal rivet or a blind rivet. Further, since the coupling means may be any means that can be coupled so as to be rotatable at the end pieces 31b and 32b, a coupling mechanism using bolts and nuts or a coupling mechanism using pins may be used instead of rivets. However, other hinge structures or the like may be employed.

  By this connecting means, the water return plate element 31 and the water return plate element 32 are rotatably connected at both ends, and as shown in FIGS. 6 (A) to 6 (C), the inclined piece 31c and the inclined piece. The angle θ formed by 32c can be changed. For this reason, since the water return plate 30 can match the inclined pieces 31c and 32c with the slope of the roof, it can be adapted to various roof slopes.

  Next, the attachment procedure of the building ventilation apparatus 1 is demonstrated. First, the field board 8 of the ridge of the roof 40 is cut and the opening part 40a is created. Next, the roofing 9 is attached to the field board 8. On the roofing 9, the inclined pieces 31 c and 32 c of the water return plate 30 are arranged. At this time, as shown in FIGS. 6A to 6C, the water return plate bodies 31 and 32 of the water return plate 30 are relatively rotated to adjust the angle θ formed by the inclined pieces 31c and 32c, The inclined pieces 31c and 32c are made to follow the roof slope. Next, a fixing tool such as a nail (not shown) is driven into the inclined pieces 31c and 32c and fixed to the roof.

  Next, as shown in FIG. 2, the roofing material 10 is attached to the roofing 9 with the inclined pieces 31c and 32c interposed therebetween. Thereafter, a waterproof tape (not shown) or the like is attached so that water does not enter between the roof material 10 and the water return plate 30. In addition, sealing is performed by caulking or waterproof tape so that water does not enter between the end portion of the water return plate 30 and the roof 40, between the end pieces 31b and 32b, and the coupling mechanism using rivets.

  Next, the headboard 20 is fixed on the roof material 10 by a fixing tool 22 such as a nail. Next, the ventilator main body 2 is fixed on the headboard 20 with the fixture 23 such as a nail by aligning the side portion of the headboard 20 and the side surface 11j of the main body member 11.

  As described above, the ventilator main body 2 is coupled to the pair of main body members 11 at the hinge 13 so as to be rotatable, and the cover 26 is attached to the main body member 11 of FIG. After fitting the drain hole cover 19 into the drain hole 11 i, the upper cover 14 is attached with screws 15 and 16. Further, at the end in the longitudinal direction of the main body member 11, the screw 17 is inserted into the screw insertion hole of the lid plate 21 and fixed by screwing into the tapping holes 11a, 14b, 11b, 11c.

  At the end of the ventilator body 2, the end cap 3 is fixed to the ventilator body 2 with screws (not shown) while the sealing material 5 is sandwiched between the ventilator body 2 and the end cap 3. Further, as shown in FIG. 1, the end cap 3 is attached so that the ridge cover 4 is positioned below the end cap 3. In addition, sealing between the cover plate 21 and the main body member 11 and the cover 26 and between the end cap 3 and the ridge cover is performed by caulking or the like as necessary. A ridge board (not shown) is attached under the ridge cover 4.

  The ridge ventilation device 1 has a hut back through the opening 40a of the roof 40, the vent 30a of the water return plate 30, the central portion 2a (see FIG. 2) of the ventilation device body 2 and the ventilation opening 14a of the upper cover 14. And ventilation outside the building is possible.

  Further, even when water such as rainwater enters from the ventilation opening 14a, the rising piece 11e of the main body member 11 prevents water from entering the central portion 2a of the ventilator main body 2, and the water The dead weight moves along the inclination of the inclined piece 11k, and the water is discharged to the outside through the drain holes 11g and 11i. Even when water is present outside the vent hole 30a of the water return plate 30, the opening 40a is surrounded by the vertical pieces 31a and 32a and the end pieces 31b and 32b constituting the vent hole 30a of the water return plate 30. Therefore, the water is prevented from entering the back of the hut through the opening 40a.

  In this way, the water return plate 30 is configured to be rotatable by configuring a rotation axis parallel to the longitudinal direction of the ridge by the coupling mechanism 34 as a coupling means, so that the angle formed by the inclined piece 31c and the inclined piece 32c is adjusted. can do. Therefore, the water return plate 30 can be adapted to various roof ridge angles. This eliminates the need to manufacture water return plates at construction sites that require a certain level of skill, and can reduce variations in the quality of the water return plates without the need for skilled workers. Variations in the quality of the building ventilation device 1 using the plate 30 can also be reduced. In addition, since it is known that the water return plate 30 matches the angle of various roof ridges within the range of the rotatable angle, the water return plate 30 can be used without checking the exact angle of the roof ridge. Since it can be procured, there is no need for the process of manufacturing or procuring a water return plate that accurately matches the angle after confirming the angle of the roof ridge at the construction site as in the past. improves.

  In the present embodiment, the inclined pieces 31 c and 32 c of the water return plate 30 are attached between the roofing 9 and the roof material 10, but the inclined pieces 31 c and 32 c of the water return plate 30 are mounted on the roof material 10. It may be attached.
