  The present invention relates to a structure of a roof ridge such as a close-up ridge or a single-flow ridge.

  2. Description of the Related Art Conventionally, various roof ridge structures have been proposed in order to prevent intrusion into the room due to rainwater blowing (see, for example, Patent Document 1).

  FIG. 6 shows the structure of the roof ridge formed by the heat insulating roof panel 20. As shown in FIG. 7, the heat insulating roof panel 20 is formed by interposing a heat insulating material 23 between a front surface skin 21 and a rear surface skin 22 which are two metal skins. In addition, a plurality of peak portions 1 project from the surface (upper surface) of the heat insulating roof panel 20, and a flat valley portion 5 is formed between the adjacent peak portions 1 and 1. As shown in FIG. 8, such a heat insulating roof panel 20 is placed on a building housing 3 such as a main building so that the longitudinal direction of the mountain portion 1 is parallel to the inclination direction of the roof, and then a tex (drill screw). ) And the like, and the roof can be formed by fixing a plurality of heat insulating roof panels 20.

  As shown in FIG. 6, in the roof ridge, a packing 28 made of urethane or the like is interposed between the ridge side end surfaces of the heat insulating roof panels 20, 20 arranged opposite to the left and right. Moreover, the ridge 4 is arrange | positioned so that the upper surface of the ridge side edge part of the heat insulation roof panels 20 and 20 opposingly arrange | positioned right and left may be covered. Further, in this ridge portion, a water return portion 30, an overflow surface door 31, an apron member 32, and the like are provided in order to improve waterproofness.

  The water return portion 30 is formed in the valley portion 5 of the heat insulating roof panel 20 by bending so that the ridge side end portion of the surface outer skin 21 rises obliquely upward. The overflow face door 31 is formed by a member having a substantially U-shaped cross section or a substantially R-shaped cross section that opens to the ridge side, and on the eaves side of the water return portion 30 (lower side in the inclination direction of the roof). It is disposed in the valley 5. Further, a sealing tape 33 is filled between the upper surface of the overflow surface door 31 and the upper surface of the mountain portion 1 and the lower surface of the wing 4, and as shown in FIGS. On the eaves side, a gap between the lower end of the overflow face door 31 and the surface (upper surface) of the valley 5, a gap between the side end of the overflow face door 31 and the side face of the mountain portion 1, and the upper surface and ridge of the mountain portion 1 Sealing material 34 is filled so as to close the gap with the lower surface of the packet 4. Further, the apron member 32 is disposed in the valley portion 5 on the eaves side of the sealing material 34. The apron member 32 is composed of a shielding plate 32a and a locking piece 32b provided at the upper end of the shielding plate 32a, and both ends of the locking piece 32b are locked to the upper surface of the mountain portion 1 and fixed. . The side end portion of the shielding plate 32a of the apron member 32 disposed in the valley portion 5 is in contact with the side surface of the peak portion 1, but the lower end of the shielding plate 32a is not in contact with the surface of the valley portion 5, A gap 50 of about 5 mm is provided. The gap 50 is provided to drain water when rainwater (see arrow A) enters between the apron member 32 and the overflow face door 31.

However, in the structure of the ridge, the raindrop 51 having a momentum may hit the overflow face door 31 through the gap 50 (see arrow a), and the waterproofness may be reduced by the raindrop 51. there were. In other words, the clearance between the lower end of the overflow surface door 31 and the surface (upper surface) of the valley portion 5 and the clearance between the side end of the overflow surface door 31 and the side surface of the peak portion 1 are blocked by the sealing material 34. Although the raindrop 51 does not enter, the upper surface of the overflow door 31 is only held by the ridge 4 with the sealing tape 33 interposed therebetween, so there is a possibility that a pinhole will occur. If the rainwater adheres to the pinhole, raindrops 51 may enter the interior due to a pressure difference between the inside and outside, and the waterproofness may be reduced.
