is thatched. Purlins 13 running in a direction perpendicular to the rafters 11 are fixed to the upper ends of the rafters 11 on both slopes of the roof 1, respectively. A draining board 3 made of a metal plate is placed spanning between both purlins 13. A waterproof sheet 17 is interposed between the draining board 3 and the purlin 13. Drain board 3
is bent into a roof shape at the center in the width direction, and leg pieces 14 extend from both edges in the width direction. The leg pieces 14 are bent inward along the slope of the roof 1. A pair of ventilation holes 2 are opened on both sides of the top of the draining plate 3. The periphery of the vent 2 rises upward to form the rim 1.
5 is formed so that water transmitted on the draining plate 3 does not enter the vent 2. A support 6 is arranged on the draining plate 3. As shown in FIGS. 4 and 5, a pair of positioning protrusions 20 are formed on the upper surface of the draining plate 3, corresponding to the mounting positions of the support 3.
The support 3 is arranged astride between both the purlins 13,
It has legs 16 fixed to the purlin 13 at both ends.
A fixing member 18 such as a nail passing through the draining board 3 and the waterproof sheet 17 is fixed to the purlin 13 through this leg 16. The width of the support 6 along the longitudinal direction of the ridge is smaller than the diameter of the ventilation opening 4 provided in the ridge tile 5. The ridge tile 5 is placed on the support 6, and
Both ends in the width direction are placed on both ends of the draining plate 3 in the width direction. As shown in FIGS. 4 and 5, the ridge tile 5 is made of an inorganic material such as cement,
A joint portion 18 having a substantially L-shaped cross section is formed at one end in the longitudinal direction of the ridge. To arrange the ridge tiles 5, the other end of the ridge tile 5 and the horizontal piece of the joint part 18 may be connected one after another so as to overlap inside and outside. A groove 19 is formed along the circumferential direction on the outer peripheral surface of the horizontal piece of the joint portion 18, and rainwater that enters from the joints between the ridge tiles 5 is drained through the groove 19, so that rainwater does not enter the ridge tile 5. I have to. Each ridge tile 5 is formed with one ventilation opening 4 that passes through it vertically. The ridge tile 5 is arranged so that the ventilation opening 4 is located at a position apart from the ventilation opening 2 of the draining board 3 along the longitudinal direction of the ridge, and the ventilation opening 4 and the support 3 correspond to each other. That is, as described above, by aligning the position of the support 3 with the positioning protrusion 20 of the draining board 3 and matching the ventilation hole 4 of the ridge tile 5 with the support 3, the ventilation hole 2 and the ventilation hole 4 can be connected. The ventilation opening 4 and the joint part 19 are provided at mutually opposite ends along the longitudinal direction of the ridge tile 5,
This makes it easier to shut off the rain than if both were provided at the same end. That is, the number of vent holes 2 provided in the draining plate 3 can be increased, and the amount of ventilation can be increased. The ventilation port 4 is covered with a perforated plate 7, and the perforated plate 7
The peripheral edge of is placed on the upper surface of the peripheral edge of the ventilation opening 4.
A bolt-like connector 8 is inserted through the center of the perforated plate 7, and the connector 8 is connected to the support 6 through the ventilation opening 4. That is, the support 6 and the perforated plate 7 are connected by the connector 8, and the peripheral edge of the ventilation port 4 is held between the support 6 and the perforated plate 7. Thereby, the ridge tile 5 is held on the roof 1. By the way, if the slope of the roof is steep, the leg piece 14 of the draining plate 3 can be raised upright as shown in FIG.
The lower end of 4 may be brought into contact with the roof 1.
In this way, by changing the bending angle of the leg piece 14 according to the slope of the roof 1, the draining plate 3 can be brought into contact with the roof 1 without changing the bending angle of the widthwise central portion of the draining plate 3. Rainwater that enters through the ventilation openings 4 and the joints of the ridge tiles 5 can be transmitted through the draining plate 3 and smoothly drained. In this way, when the roof slopes are different, the angle of inclination of the upper surface of the ridgepole 13 is the same as that of the draining plate 3.
The batten 21 may be arranged between the purlin 13 and the rafter 11 so as to match the slope of the roof. Also, the 6th
As shown in the figure, the leg piece 14 is not provided on the draining plate 3,
A horizontal piece of an accessory 22 made of inorganic material such as cement and having a substantially L-shaped cross section is placed between the ridgepole 13 and the drain board 3, and the lower end of the vertical piece of the accessory 22 is brought into contact with the top of the roof 1. Good too. If a plurality of grooves 23 running in the longitudinal direction of the ridge are formed vertically and spaced apart on the outer surface of the vertical piece of the accessory 22, it can be formed to have an appearance similar to a roof tile, and the ridge part can be made to have an excellent appearance. It can be finished in appearance. 24 in the diagram is the ridgepole 13 and accessories 22
This is an auxiliary material for adjusting the height of the

As described above, the present invention includes a ventilation hole that penetrates vertically in the ridge tile at a position corresponding to the top of the ridge, and a drainage plate that is placed inside the ridge tile and straddles the ridge of the roof. A vent that penetrates vertically is formed at the corresponding position, and the attic and the outdoors are communicated through the vent and the vent, so there is little resistance to the air flow path during ventilation, and the wind passing near the vent This increases the suction force of air from the ventilation openings and improves ventilation efficiency, and since ventilation openings are formed that penetrate the ridge tiles vertically at positions corresponding to the top of the ridge, ventilation efficiency is not affected by wind direction. It has the advantage of In addition, since the vents are placed at different positions along the length of the building, rainwater from the vents does not enter the vents, making it easier to shut off rain. Furthermore, since the ventilation opening is covered with a perforated plate, there is an advantage that birds and the like cannot crawl into the ridge tile and make nests therein. Moreover, the support placed inside the ridge tile and fixed to the ridgepole and the perforation plate that covers the top surface of the ventilation hole are connected by a connector that passes through the ventilation hole, and the peripheral edge of the ventilation hole is connected between the support and the perforation plate. This has the advantage that the ridge tile can be securely fixed on the roof because it is held between the ridge tiles.
