Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a mirrored corner used to cover the corner of a horizontal I-naiding used as an exterior material for a building, and a method for manufacturing the same. be.

(Prior Art) A conventional armor-shaped corner for horizontal siding is made of two members 20a in which the corner main body is divided into upper and lower halves as shown in Figures 17 to 19.
, 20b, and during construction, the bent portion 21b formed at the lower end of the upper member 20a is overlapped at the step 23 on the surface of the horizontal siding body 22, and the bent portion 21b is formed at the edge of the bent portion of the upper member 20a. The bending claw part 24 is bent onto the bending part 21b of the lower member 20b to connect both the bending parts 21a and 21b together, and the manufacturing process is also similar to that of the upper member 20a and the lower part. The member 20b was manufactured on a separate production line.

(Problems to be Solved by the Invention) However, in the conventional mirrored corner described above, since the upper member 20a and the lower member 20b are connected by the bent claw part 24, the 8th position of the part can be easily fixed. It loosens and becomes loose in a short period of time, and since the connection work is done manually on site, it is not only extremely dangerous to have a fingertip etc. caught, but also the surface of the mirrored corner main body cannot be adjusted in the required vertical direction. There was a problem in that it was not easy to form a decorative surface consisting of a continuous inclined surface and a horizontal surface, and when manufacturing it, the upper member 20a and the lower member 20b had different shapes, so it was difficult to form a decorative surface. had to be manufactured on a separate manufacturing line, which caused problems such as a complicated manufacturing process.

The present invention solves the above-mentioned problems, and by forming the rectangular projecting corner main body with a single thin metal plate, the upper and lower members are composed of one piece, thereby significantly simplifying the manufacturing process, and making it possible to By eliminating the connecting part between the member and the lower member, there is no looseness in this part, and there is no damage to fingertips etc. during construction.Moreover, the surface of the mirrored corner main body has the required slope and horizontal surface. It is an object of the present invention to provide an armor-shaped corner for wood clad siding that can be easily formed and a method for manufacturing the same.

(Means for Solving the Problems) In order to solve the above-mentioned problems, the present invention provides an armor-shaped corner for horizontal siding, which is the first invention, by moving both side edges of the corner from the vertical center to the back side at a required angle. The thin metal plate is folded from the front side of the thin metal plate toward the back side of the vertically rectangular thin metal plate made of a single plate bent to have a substantially V-shaped cross section, and is folded from the front side of the thin metal plate toward the back side of the thin metal plate. A substantially inverted triangular folded overlapping portion is formed on the back surface of the thin metal plate, and the left and right thin metal plate surfaces of the folded overlapping portion are inclined at a predetermined angle from the front side to the back side. A substantially horizontal bending step is formed approximately in the middle of the upper and lower parts from the front side to the back side, and a vertically elongated incision hole and notch of the required length are formed at the cough step and immediately below the step for bending and overlapping. A tongue piece is provided, and the bending and overlapping tongue piece is bent and overlapped toward the back side of the thin metal plate, and the left and right thin metal plate surfaces of the bending and overlapping part are tilted at a required angle from the front to the back side. Further, the lower edge of the thin metal plate is bent approximately horizontally toward the back side from the upper edge of the notch for forming a horizontal bent edge provided approximately at the center of the lower edge of the thin metal plate. When bent, the tongue portion of the notch overlaps the other horizontal bent edge to form a horizontal bent edge.
