(1) The joiner 29 has a shape along the inner surface of the decorative material 5 .

Here, let the decorative material 5 be a metal long material. The decorative material 5 is formed to have a substantially constant thickness. The decorative material 5 may have any cross-sectional shape, but in this embodiment, it is roughly divided into a decorative material upper part 31 and a decorative material lower part 32 . The decorative material upper component part 31 and the decorative material lower component part 32 may be configured separately, but in this embodiment, they are integrated.

The decorative material upper component 31 substantially corresponds to the upper portion of the pouch frame 13 . The upholstery upper component 31 has, for example, a substantially horizontal upper mounting portion 33 that is attached from above to the upper portion of the pouch frame 13 and a gentle downward slope from the outer edge of the upper mounting portion 33 outwardly. It has an oblique extension 34 that extends outward and a downward extension 35 that extends slightly downward from the outer edge of the oblique extension 34 .

The upper mounting portion 33 abuts on the upper flange portions 36 of the eaves side frame member 16 and the pair of side frame members 18 and 19 having a C-shaped cross section, and a fixing member such as a screw is attached to the flange portion 36 from above. 24 fixed downward. The upper mounting portion 33 has a length substantially equal to the width of the flange portion 36 when viewed from the side. A sealing material 37 is interposed between the upper mounting portion 33 and the upper flange portion 36 . A sealant 49 (FIG. 3) is applied to the fixing member 24 such as a screw.

The inclined extension portion 34 extends obliquely downward longer than the upper mounting portion 33 when viewed from the side. The downward extending portion 35 is shorter than the upper mounting portion 33 and extends almost directly downward when viewed from the side.

The decorative material lower component part 32 substantially corresponds to the part from the intermediate part to the lower part of the pouch frame 13 and is installed in a state spaced outward from the pouch frame 13 .

A lower transverse portion 45 extending substantially horizontally or inclined with a gentle downward slope to a length reaching the opposite eaves material receiving bar 27, and an inner edge of the lower transverse portion 45 extending to the outside of the eaves material receiving bar 27. It has a lower mounting part 46 which extends almost right down along the side surface and is mounted sideways from the outside with a fixing member 26 such as a screw to the lower part of the side surface of the eaves material receiving bar 27. - 特許庁

The upper transverse portion 41 extends approximately the same as or slightly longer than the downward extension portion 35 when viewed from the side. The descending portion 42 extends approximately the same as or slightly longer than the oblique extension 34 when viewed from the side. The lower inclined portion 44 extends longer than the downward extension portion 35 when viewed from the side. The lower lateral portion 45 is formed to have a length reaching the side surface of the eaves material receiving bar 27 when viewed from the side. The lower mounting portion 46 is formed to have a length reaching the lower end of the eaves material receiving bar 27 when viewed from the side. A projecting portion 46 a slightly extending outward may be formed on the lower edge portion of the lower mounting portion 46 .

The shape along the inner surface of the decorative material 5 means a shape that has substantially the same shape as the inner surface of the decorative material 5 and is in contact with the inner surface of the decorative material 5 with almost no gap, or a shape that conforms to the inner surface of the decorative material 5. It is a shape facing each other with a small gap. The narrow gap is a gap narrow enough to retain the rainwater 22 by surface tension. The small spacing is preferably on the order of 1 mm or less.

The joiner 29 is, for example, a fitting having a relatively narrow width that is approximately twice the amount of attachment required to attach it to the end of the decorative material 5 . The joiner 29 has an upper joiner piece 47 shaped along the inner surface of the decorative material upper constituent portion 31 and a lower joiner piece 48 shaped along the inner surface of the decorative material lower constituent portion 32 . The upper joiner piece 47 and the lower joiner piece 48 may be formed integrally, but in this embodiment they are separate pieces.

The upper joiner piece 47 has a shape substantially along at least the inner surface of part of the inclined extension portion 34 and the downward extension portion 35 of the decorative material upper component portion 31 . In addition, the lower joiner piece 48 has at least portions substantially along the inner surfaces of the descending portion 42 , the lower inclined portion 44 , and the lower transverse portion 45 of the decorative material lower constituent portion 32 .

As shown in FIG. 7, the side edges of the joiner 29 are sealed to the inner surface of the decorative material 5 with a sealing agent 49 . Also, as shown in FIG. 8, the upper edge of the upper joiner piece 47 is sealed to the upper portion of the pouch frame 13 (the corner between the flange portion 36 and the web portion) with a sealant 49 .

(2) As shown in FIG. 4, the pouch main body 4 may have a waterproof sheet 51 attached to the lower part of the peripheral edge.
As shown in FIG. 5 , the waterproof sheet 51 may extend downward and be attached to the edge of the eaves material 28 attached to the lower surface of the porch body 4 .

Here, as the waterproof sheet 51, for example, as shown in FIGS. The tape-shaped waterproof sheet 51 has a width that reaches at least the edge of the eaves material 28 from the lower part of the peripheral edge of the pouch body 4 . The tape-shaped waterproof sheet 51 forms an adhesive layer 52 along at least both side edges, and by attaching a release paper 53 to the adhesive layer 52, the peripheral edge of the pouch body 4 and the edge of the eaves material 28 are attached. It is preferable to be able to easily affix them separately at different timings.

The waterproof sheet 51 is first adhered laterally along the lower side surfaces of the eaves side frame member 16 and the side frame members 18 and 19 that constitute the porch frame 13 while peeling off the release paper 53 positioned above. At this time, a jig such as a roller is used to firmly adhere the upper adhesive layer 52 to the lower side surfaces of the eaves-side frame member 16 and the side frame members 18 and 19 so as to prevent wrinkles. After the eaves material 28 is attached to the porch frame 13 , the adhesive layer 52 on the lower side of the waterproof sheet 51 is attached to the periphery of the eaves material 28 .

The edge of the eaves material 28 mainly refers to an end face that constitutes the peripheral portion of the eaves material 28 . The edge of the eaves material 28 may include a portion of the lower surface along the peripheral portion of the eaves material 28 .

(3) The lower portion (lower attachment portion 46 ) of the decorative material 5 may be installed so as to abut on the position of the intermediate portion of the waterproof sheet 51 .

<Action> The action of this embodiment will be described below.

The porch roof 2 is provided above the entrance door 3 of the building 1 so as to protrude the porch body 4, thereby protecting people coming in and out through the entrance from rainwater 22 and sunlight. By lining the periphery of the pouch body 4 with the decorative material 5, the appearance of the pouch body 4 can be improved. At this time, by joining the decorative material 5 with the joiner 29 , the decorative material 5 can be formed into a length and shape along the periphery of the pouch body 4 . The attachment of the decorative material 5 and the joiner 29 can be performed by, for example, bolting or riveting. Then, the cosmetic material 5 can be attached to the peripheral edge of the pouch body 4 at once in a state of being formed along the peripheral edge of the pouch body 4.例文帳に追加

<Effects> According to this embodiment, the following effects can be obtained.

(Effect 1) As shown in FIGS. 5 and 6 , the joiner 29 may be shaped along the inner surface of the decorative material 5 . As a result, a uniform narrow gap can be formed between the inner surface of the decorative material 5 and the joiner 29 over substantially the entire area of the decorative material 5 in the vertical direction. Therefore, the joiner 29 shaped along the inner surface of the decorative material 5 can have a sealing function against the rainwater 22 .

That is, the rainwater 22 that has entered the inside of the decorative material 5 from the connecting portion 61 (FIG. 12) between the decorative materials 5 is captured by the narrow and uniform gap formed between the inner surface of the decorative material 5 and the joiner 29. It can be collected and held in place by surface tension. When the amount of rainwater 22 collected in this gap increases, the rainwater 22 can flow down along the gap due to gravity, surface tension, and the like. Therefore, the path of the rainwater 22 can be limited to within the gap, and the rainwater 22 can be regulated so as not to flow sideways from the gap.

Moreover, by shaping the joiner 29 along the inner surface of the decorative material 5 , the jointer 29 and the inner surface of the decorative material 5 , and the upper edge of the upper joiner piece 47 and the pouch frame 13 . It is also possible to physically seal the portion around the joiner 29, such as between the upper portion, with the sealing agent 49.

Therefore, by using the joiner 29 having a shape along the inner surface of the decorative material 5, it is possible to reliably prevent the rainwater 22 from reaching the upper surface of the eaves material 28 with a multiple seal structure.

On the other hand, for example, as shown in the comparative example of FIG. 13, an existing joiner 63 having a shape that does not follow the inner surface of the decorative material 5 (in the figure, it has a simple C-shaped cross section when viewed from the side) is used. In this case, a large space is formed between the inner surface of the decorative material 5 and the joiner 63 (instead of the small gap as described above). And since this space is such that the rainwater 22 cannot be collected using surface tension, the rainwater 22 can move freely within the space. Then, for example, the rainwater 22 that has entered the inside of the decorative material 5 from the connecting portion 61 of the decorative materials 5 flows sideways along the decorative material 5 and flows between the porch frame 13 and the eaves material receiving bar 27. , or the gap between the eaves material receiving bar 27 and the eaves material 28, and easily reaches the upper surface of the eaves material 28. - 特許庁

(Effect 2) A waterproof sheet 51 may be attached to the lower portion of the peripheral portion of the pouch body 4 and the lower portion of the waterproof sheet 51 may be attached to the edge portion of the eaves material 28 . As a result, the waterproof sheet 51 waterproofs the portion extending from the lower portion of the pouch body 4 to the edge of the eaves material 28, and can block the entry of rainwater 22 to the upper surface side of the eaves material 28. - 特許庁Therefore, the rainwater 22 that reaches the lower part of the decorative material 5 and the joiner 29 through the gap between the inner surface of the decorative material 5 and the joiner 29 will be The waterproof sheet 51 can reliably block the intrusion and reaching the upper surface of the eaves material 28. - 特許庁

(Effect 3) The lower portion (lower attachment portion 46 ) of the decorative material 5 may be installed so as to abut on the position of the intermediate portion of the waterproof sheet 51 . As a result, the rainwater 22 reaching the lower part (lower attachment part 46) of the decorative material 5 along the inner surface of the decorative material 5 can be guided to the intermediate part of the waterproof sheet 51 and surely blocked by the waterproof sheet 51.例文帳に追加
