Therefore, the positioning accuracy between the ventilation building cover 33 and the building surface door 51 is improved, and rainwater from the drain 59 of the ventilation building cover 33 is moved to the building side by the building surface door 51. It can prevent intrusion.
[0026]
By the way, the back-up material 12 is used to form an air passage 2 that communicates with the ridges on the lower surface of the eaves tile 5 and the roof tile 1 so as to ventilate and prevent rainwater from entering the air path 2 from the eaves side. .
[0027]
As shown in FIGS. 7 and 8, notches 39 and 39 are formed in the peak portion 13 of the backup material 12 so that the convex portion 40 is left and the air passage 2 is formed. A vent hole 8 is formed at the upper end of the peak portion of the eaves tile face door 4.
[0028]
In this way, the air passage 2 extending in the direction of the eaves is formed on the lower surface side of the roof tile 1 that has been installed, and the hanging piece 6 and the eaves tile surface at the locking step 24 at the tip of the eaves tile 5 are formed. A ventilation interval 7 is formed between the door 4 and a ventilation hole 8 communicating with the ventilation path 2 is formed in the eaves tile side door covered with the hanging piece 6.
[0029]
Thus, in the ventilation path 2 formed on the lower surface side of the roof tile 1, air is vented from the eave side toward the ridge, and the rise of the temperature of the metal roof tile 1 is prevented, while the eaves tile tile door 4 side The hanging pieces 6 of the eaves tiles 5 are present on the eaves side of the ventilation holes 12 formed in the face door portion with a ventilation interval 7 therebetween, and rainwater is not blown from the ventilation holes 12.
[0030]
Further, a backup material 12 having a heat insulating property substantially matching the peaks 9 and valleys 10 on the lower surfaces of the roof tile 1 and the eaves tile 5 is laid, and the ventilation path 2 is formed in the peak portion 13 of the backup material 12. Therefore, the backup material 12 can be used for heat insulation, and the backup material 12 can be effectively used to form the ventilation path 2 to achieve good ventilation, thereby further suppressing the temperature rise of the roof tile 1. It is something that can be done.
[0031]
By the way, since the cut-and-raised piece 16 for preventing the intrusion of rainwater is formed in the vent hole 8 of the eaves tile face door 4, the intrusion of the rainwater into the vent hole 8 by the cut-and-raised piece 16 is further prevented. Is something that can be done.

【The invention's effect】
According to claim 1, the ventilation wing cover attached across the ridge has an external member and a pair of internal members, and the external member is formed on each of the eaves-side end portions of the substantially mountain-shaped upper surface portion, respectively. And the upper part of the pair of ridges provided in the ridge part by projecting the eaves side part from the lower end of the intermediate rising piece and projecting the ridge side part from the upper end of the intermediate rising piece to form an internal member in an S shape. The lower surface of the eaves side part of each internal member is placed on the eaves side end of each internal member along each rising piece of the outer member, and the upper surface part of the ridge side part of each internal member is Each of the outer members is fixed to the lower surface of the upper surface portion, and a ventilation hole is formed on the upper surface portion of the outer member that is inclined downward from the intermediate rising piece of the inner member. A drain outlet communicating with the rising piece of the external member is formed, and the internal building is located on the internal building side of the ventilation hole. First blocking piece is provided to prevent the ingress of rainwater to be prevented from entering the rain water entering from the ventilation hole below the first blocking piece at the inside of the ventilation ridge cover inside ridge side Since the second blocking piece is provided and the second blocking piece is formed by an intermediate rising piece of the internal member, hot air is led out from the ventilation hole of the ventilation building cover to ventilate the building. The rainwater that has entered through the ventilation hole can be drained from the drainage ports formed in the rising pieces on both sides of the eaves side, and is provided on the inner ridge side of the ventilation hole. Can prevent rainwater from entering the inner building side from the ventilation hole, and the second blocking piece formed below the first blocking piece also prevents rainwater from entering the inner building side. There is an advantage that you can.
[0033]
In the second aspect, in addition to the structure of the first aspect, the first blocking piece is formed by cutting and raising the ventilation wing cover at the ridge side edge of the ventilation hole, and the cutting and raising angle is an acute angle. In addition to the effect of claim 1, since the first blocking piece is cut and raised at an acute angle toward the ventilation hole at the ridge side edge of the ventilation hole, There is an advantage that rainwater can be reliably prevented from entering the building from the ventilation hole.
[0034]
In the third aspect, in addition to the configuration of the first aspect, the second blocking piece is arranged on the ridge side with respect to the first blocking piece. There is an advantage that intrusion of rainwater can be further prevented by the two blocking pieces.
[0035]
In claim 4, in addition to the structure of claim 1, in addition to the effect of claim 1, one or a plurality of blocking pieces are provided on the ridge side of the first and second blocking pieces. Thus, there is an advantage that infiltration of rainwater can be further prevented.
[0036]
According to a fifth aspect of the present invention, in addition to the structure of the first aspect, a ridge face door and a ventilation ridge that abut against the roof tile surface of the ridge and prevent rainwater from entering the ventilation wing cover through the roof tile. Since the cover is attached to the building ridge, in addition to the effect of claim 1, the positioning accuracy of the ventilation building cover and the building surface door can be improved, and the building portion is formed while forming a drain outlet in the ventilation building cover. There is an advantage that the rainwater intrusion prevention function by the face door can be enhanced.
