Is fixed to the side surface 24 a of the outer wall base portion 24 of the outer wall main body 22 via the trunk edge 45. The exterior panel accessory 30 also has a function of suppressing warping of the exterior panel 23 due to secular change.

  The exterior panel accessory 30 is formed by adhering the first member 25 covering the lower surface 23b and the front surface 23c of the exterior panel 23 and the second member 26 covering the back surface 23d of the exterior panel 23 separately from each other. The

  In the first member 25, a first vertical member 25a and a second vertical member 25b parallel to the first vertical member 25a connect a lower end portion of the first vertical member 25a and an upper end portion of the second vertical member 25b with a horizontal member 25c. It is formed in a long band shape having a substantially Z-shaped cross section. 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.

  Here, 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 the lower end of the first vertical member 31. It is a strip shape having a substantially Z-shaped cross section connected to the upper end. The first vertical member 31 is bent and formed in an arc shape along the side surface 24a of the outer wall base portion 24, and is sandwiched and attached between the trunk edge 45 and the side surface 24a. A folded portion 31 a is provided at the upper end portion of the first vertical member 31, and a folded portion 32 a is provided at the lower end portion of the second vertical member 32.

  Here, since the side surface 24a of the outer wall base portion 24 is vertically formed in an arc shape in plan view, each of the first vertical member 31, the body edge 45, the exterior panel 23, and the exterior panel accessory 30 of the draining member 21 is provided. They are formed in a parallel arc shape in plan view.

  In order to bend and form the first member 25 of the exterior panel accessory 30 along the side surface 45a of the trunk edge 45, a plurality of first concave portions 35 and a plurality of second vertical members 25b are vertically provided on the horizontal member 25c. The second recess 36 is continuously formed by drawing, and the second recess 36 protrudes toward the body edge 45 and is formed in a substantially trapezoidal shape in plan view.

  The first recess 35 has an isosceles triangle shape in plan view, and its base Q1 (between position P1 and position P1) is the same as the substantially trapezoidal base Q1 of the second recess 36. 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 exterior panel accessory 30 is formed into an arc-shaped band shape in which the second vertical member 25b has substantially the same radius as the arc surface of the side surface 45a of the trunk edge 45 by drawing the first recess 35 and the second recess 36. Easy to form.

  The first member 25 and the second member 26 are integrated by sandwiching the lower end portion 26a of the second member 26 with a U-shaped folded portion H formed at the lower end portion of the second vertical member 25b of the first member 25.

<Action of exterior panel accessory>
As shown in FIG. 5, when the radius R1 of the side surface 45a of the body edge 45 is now set, the second concave portion 36 of the second vertical member 25b of the first member 25 of the exterior panel accessory 30 has substantially the same radius R1. is there. Further, the horizontal width T of the horizontal member 25c, the trapezoidal upper base S1, the lower base S2, the side S3 of the second concave portion 36, and the first concave portion 35 necessary for bending the first member 25 into a 90-degree arc. Let N be the number.

  When the first member 25 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 from the position P of the second vertical member 25b 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 first recesses 35 is determined as N = 90 ° / θ, and the first member 25 can be easily bent to 90 degrees by drawing using the N value as a guide.

  As described above, when the first member 25 of the exterior panel accessory 30 is formed in an arc-shaped belt shape, the horizontal member 25c and the second vertical member 25b are respectively drawn into N isosceles triangular first members by drawing. By forming the concave portion 35 and the trapezoidal second concave portion 36, it is easily bent. And the 1st member 25 and the 2nd member 26 of the accessory 30 for exterior panels can adhere to the radius of the side surface 45a of the trunk | drum 45 integrally.

  Further, the first recess 35 formed in the horizontal member 25c has an isosceles triangular shape and is gradually shallowly formed from the base (between the position P1 and the position P1) to the vicinity of the first vertical member 25a which is the vertex P2. Therefore, the vicinity of the bottom can be easily bent as compared with the vertex P2.

  Therefore, the horizontal member 25c can reliably and easily form a curved surface corresponding to the side surface 45a of the body edge 45 in the horizontal plane, and the second member 26 of the exterior panel accessory 30 is also substantially flat, so that the curved surface is easily formed. Therefore, the exterior panel accessory 30 is excellent in formability, looks good, and improves quality.

  Since the first member 25 of the exterior panel accessory 30 can be formed with a simple structure in which a steel plate is simply formed by drawing a steel plate, it can be manufactured at a low cost, and leakage can be reliably prevented.

  Further, as shown in FIG. 6, the exterior panel accessory 30 includes a first member 25 and a second member 26 which are formed separately. For this reason, since the first member 25 is not surrounded by the second member 26 at the time of drawing work performed in another place, a wide processing space WS for using the press die can be secured. Since the second recess 36 can be easily drawn, the working efficiency is increased and the productivity is improved.

  In the state where the second member 26 is first attached to the trunk edge 45, the lower end portion 26a of the second member 26 is inserted and sandwiched in the folded portion H as indicated by the arrow Y, and a rivet (not shown) is used. It is fixed by.

  Preferably, drawing processing corresponding to the trapezoidal second concave portion 36 of the first member 25 is applied to the lower end portion 26a of the second member 26 and the vicinity thereof.

  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 45a of the trunk edge 45 is vertical and is formed in a curved surface other than a circular arc in plan view, the exterior panel accessory 30 is also formed corresponding to the curved surface.

  The isosceles triangle shape of the first recess 35 may be formed in an unequal triangle shape corresponding to the curved surface shape of the side surface of the trunk edge 45.

  The exterior panel accessory 30 can also be formed on the upper end of the exterior panel 23. The first member 25 and the second member 26 of the exterior panel accessory 30 can also be attached to the trunk edge 45 in an assembled state.
