  However, when the side surface 8a of the outer wall base portion 8 has a curved surface shape in plan view, the side surface 14a of the trunk edge 14 is similarly formed in a curved surface shape in plan view, so that the draining member 9 abuts on the side surface 14a of the trunk edge 14. Therefore, it is necessary to bend the draining member 9 into a curved surface shape in plan view.

  Therefore, as shown in FIGS. 7 and 8, a plurality of vertical first slits 10 (side portions 10a and 10b) are formed with a width Q in the first vertical member 9a of the draining member 9, and the diagonal member 9b By forming a second slit 11 (side portions 11a, 11b) that is continuous with the one side portion 10a of the first slit 10, the side portions 10a, 10b are brought into contact with each other, and the side portions 11a, 11b are overlapped to form the draining member 9. A curved surface was formed along the trunk edge 14. However, this method has a problem that rainwater leaks from the first slit 10 and the second slit 11.

  Therefore, the present invention has been made in view of the problems of the prior art, and an object thereof is to provide a draining member for an exterior panel accessory that can easily form a curved surface and reliably prevent water leakage.

  The invention according to claim 1 is a draining member for an exterior panel accessory disposed below an exterior panel provided at a corner of an exterior wall body of a building and fixed to a side surface of an exterior wall base portion, wherein the exterior wall The side surface of the base is vertical and has a curved surface in plan view, and the draining member is a diagonal material in which a first vertical member and a second vertical member parallel to the first vertical member are inclined downward from the lower end of the first vertical member. To form a belt having a substantially Z-shaped vertical section connected to the upper end of the second vertical member, and bending the draining member so that the first vertical member is along the side surface of the outer wall base portion, A plurality of first recesses suspended from the first vertical member and a plurality of second recesses are formed in the diagonal member by drawing, and the first recess has a substantially trapezoidal shape in plan view and protrudes toward the outer wall base portion side. The second recess is an isosceles triangle in plan view, and its base is substantially trapezoidal to the first recess. In the vertical substantially trapezoidal cross section which is continuous with the bottom, it is characterized by being progressively shallower over in the vicinity of said second uprights are the vertices of the isosceles triangle.

  Invention of Claim 2 is the draining member of the accessory for exterior panels of Claim 1, Comprising: In horizontal view circular arc shape so that said 1st perpendicular | vertical material of the said draining member may follow the side surface of the said outer-wall base part. It is characterized by being formed.

  According to the first aspect of the present invention, the plurality of first recesses suspended from the first vertical member of the draining member and the plurality of second recesses are formed in the diagonal member by drawing. At this time, the first recess is formed in a substantially trapezoidal shape when viewed from above and protrudes toward the outer wall base portion, and the second recess is formed in an isosceles triangle shape when viewed from the top and its base is a substantially trapezoidal base of the first recess. The vertical cross section is substantially trapezoidal, and is formed gradually shallower in the vicinity of the second vertical member, which is the apex of an isosceles triangle.

  For this reason, since the first vertical member is squeezed by the plurality of first recesses, the first vertical member is easily reduced in diameter, and can be bent along the side surface of the outer wall base portion. Similarly, since the diagonal member is squeezed by a plurality of second concave portions having an isosceles triangle shape in plan view, the diameter can be reduced while easily changing the squeezing margin from the second vertical member to the first vertical member. Can do. And the said 2nd perpendicular | vertical material also becomes a curved surface parallel to the side surface of the said outer wall base part.

  Thus, since the draining member can easily form a curved surface along the side surface of the outer wall base portion, water leakage can be reliably prevented.

  According to the invention of claim 2, since the first vertical member of the draining member is formed in an arc shape in a horizontal view along the side surface of the outer wall base portion, the same effect as the effect of claim 1 Can be obtained.

  Hereinafter, an embodiment of the present invention will be described with reference to FIGS.

<Configuration of draining member for exterior panel accessory>
As shown in FIGS. 1, 2, 3, and 4, the draining member 21 of the exterior panel accessory 25 according to the present invention is the exterior panel accessory 25 provided at the corner of the outer wall body 22 of the building. It arrange | positions below and adheres to the side surface 24a of the outer-wall base part 24. As shown in FIG.

  The exterior panel accessory 25 covering the lower end portion 23a of the exterior panel 23 is formed in a substantially U-shaped cross section formed by connecting a pair of parallel vertical members 25a and 25b and a horizontal member 25c. The horizontal member 25 c is provided with a drain hole 41 having a diameter of about 6 mm, and rainwater from the drain hole 41 can be discharged from the outer wall body 22 to the outside by the draining member 21.

  The draining member 21 is a diagonal member 33 in which a first vertical member 31 and a second vertical member 32 parallel to the first vertical member 31 are inclined downward from a lower end portion 31 a of the first vertical member 31, and an upper end portion of the second vertical member 32. The first vertical member 31 is bent in an arc shape so as to follow the side surface 24a of the outer wall base portion 24. A folded portion 31 b is provided at the upper end portion of the first vertical member 31, and a folded portion 32 b is provided at the lower end portion of the second vertical member 32.

  The exterior panel accessory 25 is fixed to the outer wall base 24 using a fixing tool 29 such as a nail together with the first vertical member 31 of the draining member 21 through the trunk edge 26 as an exterior base material. At this time, the waterproof tape 27 and the moisture-permeable waterproof sheet 28 are used between the trunk edge 26 and the first vertical member 31.

  Here, since the side surface 24a of the outer wall base portion 24 is vertically formed in an arc shape in plan view, the first vertical member 31 of the draining member 21, the trunk edge 26, the exterior panel 23, and the exterior panel accessory 25 are mutually connected. Each is formed in an arc shape in plan view so as to be parallel.

  A plurality of first recesses 35 and second recesses 36 are formed in the first vertical member 31 and the diagonal member 33 of the draining member 21 by drawing, respectively, and the first recess 35 protrudes toward the outer wall base portion 24 side in plan view. It is formed in a substantially trapezoidal shape.

  The second recess 36 is an isosceles triangle in plan view, and its base Q1 (between position P1 and position P1) is the same as the substantially trapezoidal base Q1 of the first recess 35 at the lower end 31a of the first vertical member 31. . And the 2nd recessed part 36 is formed continuously with the 1st recessed part 35, the vertical cross section of the 2nd recessed part 36 is substantially trapezoid shape, and it covers the vicinity of the 2nd perpendicular | vertical material which is the vertex P2 of the isosceles triangle shape in planar view. It is formed to gradually become shallower.

  As described above, the draining member 21 is formed into an arc-shaped long band shape in which the first vertical member 31 has substantially the same radius as the arc surface of the side surface 24 a of the outer wall base portion 24 by drawing the first recess 35 and the second recess 36. Easy to form.

  The exterior panel 23 is made of metal siding obtained by coating an internal heat insulating material with a thin metal plate from both sides for the purpose of heat insulation and sound insulation. The plurality of exterior panels 23 are assembled horizontally or vertically from the bottom to the top of the outer wall body 2.

  The draining member 21 is integrally formed by drawing a thin steel plate having a plate thickness of 0.35 mm with a sheet metal, and both surfaces are plated with aluminum / zinc alloy, and the surface side is coated with fluororesin and the back side is coated. Polyester resin coating is applied.

<Action of draining member for exterior panel accessory>
As shown in FIG. 5, the radius R1 of the side surface 24a of the outer wall base 24, the radius in the first recess 35 of the first vertical member 31 of the draining member 21 are also substantially the same radius R1, the horizontal width T of the diagonal member 33, The trapezoidal upper base S1, the lower base S2, and the side S3 of the first concave portion 35 are set, and the number of the first concave portions 35 necessary for bending the draining member 21 into a 90-degree arc is N.

  When the draining member 21 is formed from the linear state to the circular arc surface by forming the first recess 35, the angle θ changed by one first recess 35 moves the point P of the first vertical member 31 to the position P1. Since the vertex angle θ1 at the vertex P2 of the isosceles triangle is reduced to the vertex angle θ2, the reduced angle θ = vertical angle θ1−vertical angle θ2.

  Since the base reduction width W = S1 + 2 × S3-S2 at the base of the isosceles triangle, sin θ = W / T. For this reason, the required number of the first recesses 35 is obtained by N = 90 ° / θ, and the draining member 21 can be easily bent to 90 degrees by drawing using the N value as a guide.

  As described above, when the draining member 21 is formed into an arc-shaped strip having a substantially Z-shaped vertical section, N trapezoidal first recesses 35 and N are formed on the first vertical member 31 and the diagonal member 33 by drawing. By forming the second recess 36 having an isosceles triangle shape, the draining member 21 can be integrally bent and fixed in accordance with the radius of the side surface 24a of the outer wall base 24.

  Further, the second recess 36 formed in the diagonal member 33 is an isosceles triangle shape and is gradually shallowly formed from the base (between the position P1 and the position P1) to the vicinity of the second vertical member 32 which is the vertex P2. Therefore, the vicinity of the base (between the position P1 and the position P1) can be easily bent larger than the vertex P2.

  For this reason, the diagonal member 33 can reliably and easily form a curved surface corresponding to the side surface of the outer wall base 24, and the second vertical member 32 can also easily form a curved surface, so that the draining member 21 as a whole is excellent in formability. It looks good and improves quality.

  Since the draining member 21 is integrally formed with a simple structure in which a steel plate is simply formed by drawing a steel plate, leakage can be reliably prevented at low cost.

  A sealing material is applied to the gap 40 between the trapezoidal first concave portion 35 of the first vertical member 31 and the outer wall base portion 24 as necessary.

  The embodiment of the present invention has been described with reference to the drawings. However, the specific configuration is not limited to this embodiment, and design changes and the like within the scope of the present invention are included in the present invention. It is.

  For example, when the side surface of the outer wall base portion is vertical and formed in a curved surface other than the arc in plan view, the draining member 21 is also formed corresponding to the curved surface.

  The isosceles triangle shape of the second recess may be formed into an unequal triangle shape corresponding to the curved surface shape of the side surface of the outer wall base portion.

  When the outer wall main body 22 is attached so as to cover the outer wall base portion 24, the first vertical member 31 of the draining member 21 is fixed in correspondence with the outer wall main body 22.

  When the same color and the same material are used for the exterior panel accessory 25 and the draining member 21, a uniform appearance can be obtained, so that the quality is improved.

It is a partial cross section view side view of the draining member 21 of the accessory for exterior panels provided in the protruding corner part of the outer wall main body 22 of the building in embodiment of this invention. It is a perspective view of the draining member 21 in the embodiment of the present invention. FIG. 3 is an AA partial cross-sectional view of FIG.
