MANUFACTURE OF CORNER DECORATION TOOL FOR ROOF

摘要

PROBLEM TO BE SOLVED: To facilitate construction by a method wherein side protrusion parts of a given angle are formed at two side end part by using a bendable plate, and an extension part provided at an upper part with a pair of vertical parts and a downward protrusion part is formed, and the lock hook part of a corner decoration part is bent in an overlapping state on the back side. ;SOLUTION: In a corner decoration tool body 10 for a roof formed of a bendable plate, side protrusion parts 11 of a given angle are formed at end parts o both sides, and provided at an upper part with a pair of vertical part 12. A top part of a given angle is arranged on the extension line of the vertical part 12 and an extension part 14 having a down protrusion part 13 is formed. A pair of chevron-form protrusion parts 15 are formed between a pair of the vertical parts 12 and a corner decoration part 17 having a lock hook part 16 is formed in a protrusion state between the downward protrusion parts 13. A first virtual bent-up line 20 on a line to connect together a pair of the vertical parts 12 and a top part 13a of the downward protrusion part 13 is bent. Further, a second virtual bent-up line 21 and third and fourth virtual bent-up lines 22 and 23 are bent in an overlapping state a plurality of times. This constitution effects construction through one action for simplification.;COPYRIGHT: (C)1998,JPO
