Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a corner member for a horizontal interior / exterior material such as a building or a structure.

(Prior Art) Conventionally, for example, as a corner member for a horizontal covering material for buildings and structures, for example, Japanese Patent Laid-Open No. 63-93958 (hereinafter referred to as a first known example) and Japanese Utility Model Laid-Open No. 1-253030 (hereinafter referred to as a second known example). Known examples), Japanese Utility Model Laid-Open No. 62-52635 (hereinafter referred to as third known example), JP-A-59-217865 (hereinafter referred to as fourth known example) and the like are known.

That is, the above-mentioned first known example is "upper vertical center of a vertical rectangular thin metal plate made of a single plate formed by bending both side edges from the vertical center portion to the back side by a required angle to form a substantially V-shaped section. Part of the thin metal plate is folded from the front side to the back side of the thin metal plate, and a folded overlapped portion having a substantially inverted triangle is formed on the back surface of the thin metal plate to form left and right thin metal plates of the folded overlapped portion. The surface is an inclined surface that inclines from the front side to the back side at a required angle, and a substantially horizontal bent step portion is formed in the upper and lower intermediate portions of the thin metal plate with a required width from the front side to the back side. A stepwise portion and a portion directly below the stepped portion are provided with a vertically elongated incision hole and a bending overlapping tongue portion by cutting, and the bending overlapping tongue portion is bent and overlapped to the back side of the thin metal plate. Inclining the left and right thin metal plate surfaces of the folding overlap section from the front side to the back side at a required angle. No tilting surface, and further, the lower end edge of the thin metal plate is bent substantially horizontally toward the back side from the upper edge part of the horizontal bent edge forming notch portion provided substantially in the center of the lower end edge of the thin metal plate. Then, the tongue portion of the cutout is overlapped with the other horizontal bent edge to form a horizontal bent edge. The second known example is used for a projecting corner portion, and is "a horizontal direction obtained by combining an upper end portion of a lower wall plate and a lower end portion of an upper wall plate in a superposed manner. A metal cover that is covered by a plurality of long wall plates and covers the corners of the wall surfaces that intersect each other with the intersections protruding, with the middle part of the metal plate at the same angle as the intersection angle between the two wall surfaces. By bending it into a pair of left and right main cover plates, the lower edge of each main cover plate is almost right angle toward the wall surface. It is bent,
Each wall plate is a lower cover piece that covers the lower edge of each wall plate, and the upper edge of each main cover plate is turned toward the wall surface until it forms an acute angle with the main cover plate. It is a cover plate of a wall corner covered with a wall plate that is a locking piece that can be locked freely on the upper edge of the wall. is there.

Further, in the third known example, "a single long plate having elasticity is bent along the longitudinal direction into isosceles or unequal-sided mountain shapes to form a decorative surface portion, and both end edges of the decorative surface portion are inward. In a corner panel provided with a side surface portion that is bent vertically or inclined, and an edge of the side surface portion is bent inward at an acute angle to provide a hook-shaped engaging piece, a right angle of the decorative surface portion Corner panel with a chamfered cross section of 45 °, and the shape of the side surface with a plurality of mountain shapes according to the panel " It is used for a corner when a wall body is formed using a material, and the fourth known example is "a frame body such as a main body, a stud, and a long male and female type on both side edges in the longitudinal direction. A fixed length panel having a connecting part, and a band or string which is a molded body and has waterproof and cushioning properties -Shaped joint material, a short-sized fitting having a gutter-shaped cross section from the bottom and legs, and a long body having a gutter-shaped cross section corresponding to the outer shape of the fitting, and both of the decorative side surfaces. And a joint cover whose elastic side can be elastically deformed, which has a joint part formed by extending the lower end of the panel inwardly, and horizontally connects the panel on the frame body and vertically connects the male and female connecting parts. And the end faces in the longitudinal direction of each panel are placed on the frame body to form vertical joints consisting of vertical groove-like voids, and a joint material is interposed in the vertical joints. The joint is fixed to the frame body by closing the void, crossing the vertical joint with a plurality of the fittings in the vertical joints, and fixing the leg ends to the panel surface. Is a vertical joint structure of a wall using a panel characterized by being inserted through elastic deformation. It is used for a vertical joints in forming a flat exterior and tension.

(Problems to be Solved by the Invention) However, in the above-mentioned conventional technique, in the first known example, a horizontal bending step portion is provided in a substantially middle portion of the armor-shaped protruding corner body, and the upper center and the bending portion are provided. Since the folded and overlapped portion having a substantially inverted triangular shape is provided immediately below the stepped portion, there is a problem that the structure becomes complicated and processing is troublesome. Further, the locking piece of the second known example is simply a cover plate. To the upper edge of the end of the wall plate, and when removing the cover plate, pull the cover plate to be replaced strongly downward to extend the bent portion of the locking piece linearly. Since the cover plate is attached by the locking piece in an unstable manner, there is a fear that it will easily fall off, and the lower surface of the cover plate and the wall. By forming a heat insulating space between the upper surfaces of the plates, enhance the heat insulation of the part There is a problem that it is not possible, and the third known example is
There is no mounting structure that covers the male and female connecting parts of the stepped wall body on the upper and lower parts of the corner panel body and allows continuous connection in the vertical direction. When it is applied to the corner portion of the body, there is a problem that a locking tool for locking the engaging piece on the side surface portion of the corner panel body is separately required. In the case of the third known example, because of its structure, it cannot be used for the stepped wall body at all, and like the case of the third known example, both side legs of the joint cover body are locked. There was a problem such as the need for a separate mounting tool.
