That is, the above-mentioned first known example is that "a vertical rectangular upper portion of a vertical rectangular thin metal plate made of a single plate formed by bending both side edges from the vertical central portion to the back side at a required angle to form a substantially V-shaped cross section. , The thin metal plate is folded from the front of the thin metal plate toward the back side, and is formed on the back surface of the thin metal plate to form a substantially inverted triangular folded overlapped portion, and the left and right thin metal plates of the folded overlapped portion are formed. The surface is an inclined surface that inclines from the front side to the back side at a predetermined angle, and a substantially horizontal bent step portion is formed in a substantially vertical middle portion 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 the outer corner of the
"A state in which the upper end of the lower wall plate and the lower end of the upper wall plate are overlapped and covered by a plurality of horizontally long wall plates, and the intersecting portion projects. It is a metal cover that covers the corners of the wall surface that intersected with each other,
By bending the middle part of the metal plate to the same angle as the intersection angle between the two wall surfaces, a pair of left and right main cover plates are formed, and the lower edge of each main cover plate is bent at a substantially right angle toward the wall surface. Then, by making it a lower cover piece that covers the lower edge of each wall plate, and turning back the upper edge of each main cover plate toward the wall surface side until the angle formed with the main cover plate becomes an acute angle, A cover plate for corners of the wall surface covered with the wall plate, which is a locking piece that can be locked on the upper edge of the wall plate,

Further, in the third known example, "a long plate having elasticity is bent along the longitudinal direction into isosceles or unequal 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 perpendicularly or obliquely to the side surface, and an edge of the side surface portion is bent inward at an acute angle to provide a hook-shaped engaging piece, A corner panel "characterized in that right-angled corners are formed in a chamfered cross section of about 45 °, and side surfaces are formed in a plurality of mountain shapes according to the panel". It is used in the corner when a wall body is formed by using a sheet-shaped exterior material, and the fourth known example is "a frame body such as a main body or a stud, and a long body on both side edges in the longitudinal direction. A fixed length panel having male and female connecting parts, and a band having a waterproof property and cushioning property as well as a molded body, Alternatively, a string-shaped joint material, a short fitting having a gutter-shaped cross section from the bottom and legs, and an elongated body having a gutter-shaped cross section corresponding to the outer shape of the fitting, and both of them. The decorative side surface has an engaging portion formed by extending the lower end inward, and the decorative side surface is provided with a joint cover that can be elastically deformed, and the panel is horizontally placed on the frame body and vertically in the male and female directions. While connecting the connecting parts to each other, the longitudinal end faces of the respective panels are placed on the frame body to form vertical joints consisting of vertical groove-like voids, and the joint material is interposed in the vertical joints. To close the gap, and to fix the fixture to the frame with a plurality of the fixtures in the vertical joints, traversing the vertical joints, and with the tips of the legs resting on the panel surface. A vertical joint structure of a wall using a panel characterized in that a joint cover is attached through elastic deformation, It is used for a vertical joints in forming a flat outer wall and the lateral clad the panel.

(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

The portion 16a and the core material filling portion 15 on the lower surface of the projecting tongue portion 14b form a triple-layered, completely sealed armor-type structure, and as a result, the heat insulation, fire protection and strength of the portion are remarkably enhanced. It can withstand long-term use.

In the above case, it is desirable that the concave fitting portion 13b of the female coupling portion 13 and the convex fitting portion 14a of the male coupling portion 14 be in a close contact state, but in some cases, a slight gap is formed. By doing so, it is possible to facilitate the fitting and draining of both, and the tip of the folded edge 13d and the gap 1
It is also possible to provide a gap between the bottoms of 4c to facilitate heat removal and drainage by preventing capillary action.

The exterior material configured in this manner is fixed one by one from the bottom to the top. When a plurality of exterior materials are horizontally arranged side by side so that there is no step at the end facing each other, vertical joints 21 are formed between these exterior materials. Then, the joint member 22 of the present invention is attached as shown in FIG. 1 to finish the construction.

That is, when mounting the joint member 22 in the present invention,
The U-shaped fitting portion 24 formed at the lower end of the joint member 22 is fitted to the core material filling portion 13c of the exterior material as shown in FIG. 7 (a), and is formed at the upper end of the joint member 22, respectively. The bending engaging portion 25a of the stopper 25 is locked to the upper end surface 14a ″ of the convex fitting portion 14a of the male connecting portion as shown in FIG.
b is attached to the surface 14a ″ of the convex insertion portion 14a, and a nail 29 is inserted through a nail hole 27 formed in a tongue-shaped attachment portion 28 extending to the central upper end of the locking portion 25. The joint member on the wall base 19
22 can be installed easily.

Further, at this time, the joint member 22 forms a heat insulating space forming sloped portion 25c continuously with the splicing portion 25b, and the bent side surface portions 26 on both side edges are the inner bent end portions 26a, Since 26a is formed so as to correspond to the surface shape of the exterior material, the joint member 22 has a heat insulating space 23 'between the joint surface 22 and the decorative surface of the exterior material.
To form a three-dimensional structure as shown in FIG.

In the embodiment of the present invention, the case where the present invention is applied to the armor type horizontal fireproof exterior material has been described, but the present invention is not limited to this and does not change the gist of the present invention.

In addition, it is needless to say that the core material 16 or the back surface material 18 may be omitted in the exterior material according to the above-mentioned embodiment, if necessary.
