For example, as shown in FIGS. 1 and 2, the building louver panel 10 is vertically attached to a building frame 30 via a base material 31. Note that the method of attaching the building louver panel 10 is not limited to the vertical direction, and may be the horizontal direction as shown in FIG. The plurality of building louver panels 10 are arranged so as to be parallel to the adjacent building louver panels 10 at a predetermined interval so as to be attached so as to cover a wall surface or the like.

  As shown in FIGS. 3 and 4, the building louver panel 10 includes a front part 11, a side part 14 extending in a substantially right angle direction from both ends of the front part 11, and an end part of the side part 14. And a substantially L-shaped projecting piece 15 provided inside the vicinity.

  The front part 11 is a part constituting a surface facing the front when the building louver panel 10 is attached to the building frame 30. A plurality of long holes 12 are formed in the front portion 11 in parallel. The periphery of the long hole 12 formed in the front part 11 is composed of a straight part 12a and an arc part 12b, and as shown in FIG. A rectangle is formed.

  The elongated hole 12 is subjected to burring with a mold. Specifically, first, after drilling the pilot holes 13 as shown in FIGS. 5 and 6, the peripheral portions of the pilot holes 13 are cut inward by burring using a mold, 3 and a long hole 12 as shown in FIG. In this way, by forming the long holes 12 at one time by burring using a mold, a plurality of long holes 12 can be manufactured accurately and quickly.

  As shown in FIG. 6, the pilot hole 13 described above is formed at a position corresponding to the central portion 13 a and the oblique portion 13 b formed at a position corresponding to the straight portion 12 a of the long hole 12 and the arc portion 12 b of the long hole 12. The shape is a combination of the formed semicircular portion 13c. By providing the inclined portion 13b between the central portion 13a and the semicircular portion 13c, the shape of the prepared hole 13 is an elongated shape with both end portions expanded.

  By performing burring on such a pilot hole 13, when the peripheral edge of the pilot hole 13 is cut inward by burring, the portion of the arc portion 12b is more than the portion of the straight portion 12a. It is designed to be cut small. Specifically, as shown in FIGS. 3 and 4 (b), the peripheral portion of the long hole 12 cut and raised inside the building louver panel 10 was cut and raised at the center portion 13a of the pilot hole 13. The center portion 12c is formed by a central portion 12c, a bevel portion 13b of the lower hole 13 which is cut and raised, and a semicircle portion 12e of which the semicircle portion 13c of the lower hole 13 is cut and raised. Then, the oblique cut and raised 12d forms a step so that the semicircular cut and raised 12e is cut and raised smaller than the central cut and raised 12c.

  Since the semicircular cut and raised portion 12e is cut and raised smaller than the central cut and raised portion 12c in this way, the arc portion 12b is not greatly stretched, so that cracking and cracking due to burring can be prevented. .

  The side surface portion 14 extends in a substantially right angle direction from both ends of the front surface portion 11 in the short direction (width direction). The side surface portion 14, together with the front surface portion 11, forms a substantially U-shaped cross section as shown in FIG.

  The protruding piece 15 is a substantially L-shaped portion provided to protrude inward in the vicinity of the end portion of the side surface portion 14.
