Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to an armor-shaped corner used to cover the corner of horizontal siding used as an exterior material for a building, and a method for manufacturing the same. . [Prior Art] The present applicant has previously disclosed an armor-shaped corner used for covering the corner of horizontal siding used as an exterior material for buildings and a method for manufacturing the same (Japanese Patent Application Laid-Open No. 1983-1989-1).
93958) was developed. [Problems to be Solved by the Invention] However, the above-mentioned prior art involves bending both side edges of a vertically rectangular thin metal plate from its longitudinal center portion toward the back side at a required angle to form a substantially V-shaped cross section. , a substantially inverted triangular folded overlapping part that is folded into the upper vertical center of the vertically rectangular thin metal plate from the front side of the thin metal plate toward the back side and overlapped with the back side of the thin metal plate; and a horizontal bending step located approximately in the middle between the upper and lower parts of the thin metal plate, and a tongue piece for folding and overlapping formed by an elongated incision hole and a notch of the required length in the vertical center immediately below the step. Further, a notch for forming a horizontal bent edge is provided approximately at the center of the lower edge of the thin metal plate, and each of these inverted triangular folding and overlapping parts, a longitudinal cut hole and a tongue piece for bending and overlapping formed by the notch is provided. However, since the notch for forming a horizontal bent edge was used, when the thin metal plate was bent, cracks occurred in the plate from the vertically elongated cut hole and the highest corner of the notch for forming a horizontal bent edge. In recent years, there has been a concern that the walls have deteriorated in their design (good appearance), as this has caused the board to crack and invite rainwater to enter through the cracks, reducing its function as an exterior wall material.
