[0027] <Installation method for rain gutter ventilation components> The construction of the rain flashing ventilation member 6 is carried out as follows.

[0028] First, a ventilation hole 3 is provided at the boundary between the exterior wall 1 and the roof 2 of a building. The exterior wall 1 is, for example, a second-floor exterior wall, and the roof 2 is a first-floor roof provided in front of the exterior wall 1. The exterior wall 1 is formed by placing a breathable waterproof sheet 12 on the front of a wall base 11, placing furring strips 13 on the front of the breathable waterproof sheet 12, and providing exterior wall materials 14 on the front of the furring strips 13 (see FIGS. 6A and 6B). The roof 2 is formed by providing a sheathing 22 on the top surfaces of rafters 21, placing underlayment materials 23 on the top surface of the sheathing 22, and providing multiple roofing materials 20 on the underlayment materials 23 (see FIGS. 6A and 6B). In this embodiment, the roofing material 20 has a corrugated surface that is concavely curved upward.

[0029] As shown in Figures 3 and 6B, ventilation hole 3 is formed below furring strips 13 and exterior wall material 14, between wall underlayment 11 and roof material 20. Ventilation hole 3 is connected to the space below roof 2 (attic space). Ventilation hole 3 is surrounded by flashing 31. On the outer side of flashing 31, battens 80 are provided between roof material 20 and wall underlayment 11, and capping board 81 is provided on top of battens 80. Furthermore, on the inner side of flashing 31, central battens 82 are provided between roof material 20 and wall underlayment 11, and central capping board 83 (capping board 4) is fixed on top of central batten 82 with fasteners 84 such as nails. Central batten 82 and central capping board 83 are provided in approximately the center of ventilation hole 3 in the horizontal direction.

[0030] A joint member 85 is provided on the coping 81. The joint member 85 connects the rain flashing ventilation member 6 and the rain flashing 9. The joint member 85 has a mounting piece 851, an attachment piece 852 that protrudes upward from the rear end of the mounting piece 851, and a front piece 853 that protrudes downward and forward from the front end of the mounting piece 851. A waterproof member 854 is provided extending from the attachment piece 852 to the front piece 853.

[0031] The flashing 9 is a component arranged to waterproof the exterior wall 1 and the roof 2. The flashing 9 has a cover portion 91, an attachment piece 92 that protrudes upward from the rear end of the cover portion 91, and a front piece 93 that protrudes downward and forward from the front end of the cover portion 91.

[0032] The joint member 85 is then placed on the end of the head board 81. At this time, the mounting piece 851 is placed on the top surface of the head board 81, the front piece 853 is positioned in front of the head board 81, and the mounting piece 852 is positioned in front of the wall base 11. Next, the end of the flashing 9 is positioned so as to cover approximately half of the lateral direction of the joint member 85 from above. At this time, the cover portion 91 is positioned above the mounting piece 851, the front piece 93 is positioned in front of the front piece 853, and the mounting piece 92 is positioned in front of the mounting piece 852. In addition, a waterproof member 854 is interposed between the joint member 85 and the end of the flashing 9. The joint member 85 and the flashing 9 are fixed with fasteners 95 such as screws or nails. The fasteners 95 are driven into the front pieces 853 and 93 from the front to the head board 81.

[0033] Next, the ventilation flashing member 6 is installed. In this case, the lateral end of the ventilation flashing member 6 is placed on the joint member 85. The coping board 81 and the mounting piece 851 are accommodated in the end accommodating space 66, and the coping board 81, the mounting piece 851, and the front piece 853 are positioned behind the support piece 614. A waterproof member 854 is interposed between the joint member 85 and the end of the ventilation flashing member 6. The central coping board 83 is accommodated in the accommodation space 67 located approximately in the center of the ventilation flashing member 6. That is, the central support piece 614 and the approximately central portions of the fixing pieces 60 are located in front of the central coping board 83.

[0034] After this, the ventilation flashing member 6 is fixed to the coping board 81 and the central coping board 83 with fasteners 7 such as screws or nails. At this time, the fasteners 7 are driven from the front of the ventilation flashing member 6 through the fixing pieces 60 and support pieces 614 and into the coping board 81 and the central coping board 83. The ventilation flashing member 6 installed in this manner has the ventilation holes 3 and the air passage 5 in communication. Therefore, ventilation can be achieved from the attic space below the roof 2 through the ventilation holes 3 and the air passage 5.

[0035] A waterproofing member 100 may be provided in the gap between the roofing material 20 and the ventilation flashing member 6. The waterproofing member 100 is provided to close the gap formed between the surface of the roofing material 20 closest to the wall underlayment 11 and the underside of the lower piece 612 of the base member 61 of the ventilation flashing member 6. The waterproofing member 100 can be made of a material that can ensure long-term waterproofing, such as ethylene propylene rubber (EPDM) foam or a silicone-based caulking material. When the gap is closed using the elasticity of the material (such as EPDM), the ventilation flashing member 6 is fixed to the eaves-side surfaces of the coping board 81 and the central coping board 83 with fasteners 7 such as screws or nails, which prevents the ventilation flashing member 6 from lifting up due to the elasticity of the waterproofing member 100.

[0036] In this embodiment, the ventilation flashing member 6 is fixed to the coping board 81 and the central coping board 83 from the front with the fasteners 7, making it less susceptible to the surface shape of the roofing material 20. This allows use on roofs 2 with roofing materials 20 that have large uneven patterns. Furthermore, the fastening portions with the fasteners 7 are the locations where the support pieces 614 of the base member 61 and the fixing pieces 60 of the cover member 62 partially overlap, ensuring wind resistance. Furthermore, the ventilation flashing member 6 is fixed at its longitudinal center to the central coping board 83, providing improved fixing strength compared to conventional methods. Furthermore, when fixing the ventilation flashing member 6, the fasteners 7 do not penetrate the roofing material 20, making it less likely to reduce waterproofing.

[0037] (Variation) The first embodiment is merely one of various embodiments of the present disclosure, and various modifications can be made to the first embodiment depending on the design and the like, as long as the object of the present disclosure can be achieved.

[0038] In the above description, one storage space 67 is formed in approximately the center of the ventilating flashing member 6 in the horizontal direction, and the central coping 83 is provided at a position corresponding to this storage space 67. However, this is not limited to this. If the ventilating flashing member 6 is longer in the horizontal direction, multiple storage spaces 67 may be formed evenly (not necessarily evenly) in the horizontal direction, and multiple copings 4 may be provided at positions corresponding to these multiple storage spaces 67. Furthermore, while the roofing material 20 has been exemplified as having a corrugated surface, such as a Japanese roof tile, this is not limited to this. The roofing material 20 may be formed in a three-dimensional shape with multiple inclined surfaces on its surface that have different inclination directions. Furthermore, the roofing material 20 may not have a three-dimensional surface, but may be flat.

[0039] (summary) As described above, the construction of the ventilation flashing member 6 according to the first aspect includes an exterior wall 1, a roof 2 provided in front of the exterior wall 1, ventilation holes 3 provided between the exterior wall 1 and the roof 2, a coping board 4 disposed above the ventilation holes 3, and a ventilation flashing member 6 having an air passage 5. At least one coping board 4 is disposed at a predetermined position in the longitudinal direction of the ventilation holes 3. The ventilation flashing member 6 is disposed so that the ventilation holes 3 and the air passage 5 communicate with each other, and so as to cover the entire length of the area above the ventilation holes 3. The ventilation flashing member 6 has a fixing piece 60 located forward of the coping board 4. The fixing piece 60 is fixed to the coping board 4 by a fastener 7 driven in from the front.

[0040] According to this embodiment, the roof 2 is not fixed to the roof material 20, but is fixed by driving the fastener 7 into the coping 4 from the front, so it is not affected by the shape of the roof material 20, and further, since the fastener 7 is not driven into the roof material 20, there is an advantage in that waterproofing is improved.

[0041] The second embodiment is a construction for installing the rain flashing ventilation member 6 of the first embodiment, in which the roof material 20 installed on the roof 2 has a three-dimensional shape on the surface.

[0042] This embodiment has the advantage that the roof material 20 can be fixed without being affected by its shape.

[0043] The third aspect is a ventilation flashing member 6 used in the construction of the ventilation flashing member 6 of the first or second aspect, and includes a base member 61 and a cover member 62 arranged above the base member 61. An air passage 5 is formed between the base member 61 and the cover member 62. The base member 61 is formed with a storage space 67 for storing the coping 4. A fixing piece 60 is formed in front of the storage space 67.

[0044] According to this embodiment, the roof 2 is not fixed to the roof material 20, but is fixed by driving the fastener 7 into the coping 4 from the front, so it is not affected by the shape of the roof material 20, and further, since the fastener 7 is not driven into the roof material 20, there is an advantage in that waterproofing is improved.
