Hereinafter, an exterior structure according to the present invention will be described in detail with reference to the drawings. FIG. 1 is a cross-sectional view showing a fitting state when the exterior material Y is used as a roofing material, and FIG. 2 shows a cross section of a long exterior material Y composed of a metal plate material I, a heat insulating material D, and a back surface material R. Is. 3 is an exterior material Y2 made of a metal plate I, and FIG. 4 is a reference perspective view of the exterior material Y. FIG.

As a typical example of the exterior structure according to the present invention, an exterior material Y made of a metal plate material I and a heat insulating material D and a back surface material R as shown in FIG. 2, and an exterior material made of a metal plate material I as shown in FIG. Material Y2 is conceivable. These are long or short.

The metal plate material I is formed, for example, by roll forming, press forming, extrusion forming, or the like of a metal plate (color steel plate, copper plate, aluminum plate, titanium plate, stainless steel plate, sandwich steel plate, clad steel plate, etc.).

The heat insulating material D functions as a waterproof material, a heat insulating material, a reinforcing material, a raising material, a sound insulating material, a sound absorbing material, a shock absorbing material, a fireproofing material, a dew condensation preventing material, etc., and mainly uses a synthetic resin foam. To do. The material is a synthetic resin foam such as styrene foam, polyurethane foam, polyisocyanurate foam, phenol foam, vinyl chloride foam, polyethylene foam, polystyrene foam, urea foam and the like.

In addition, in the heat insulating material D, lightweight aggregates (perlite grains, glass beads, gypsum slag, talc stone, shirasu balloon, aluminum hydroxide, etc.), fibrous materials (glass wool, rock wool, carbon fiber, Graphite and the like) can be mixed to improve fire resistance and fire resistance.

Back material R is 1 such as kraft paper, aluminum evaporated paper, asphalt felt, metal foil (Al, Fe, Pb, Cu), synthetic resin sheet, rubber sheet, cloth sheet, gypsum paper, aluminum hydroxide paper, glass fiber nonwoven fabric, etc. It is composed of a seed, or a laminate of two or more kinds, or a sheet subjected to waterproof treatment or flame retardant treatment.

More specifically, as shown in FIG. 2, the exterior material Y bends the lower end portion of the decorative surface K toward the interior of the exterior material Y to form the stepped decorative surface DK, and the tip of the stepped decorative surface DK is folded upward to lower the lower edge E. Form. Thereby, the protrusion fitting female part M which consists of the decorative surface K, the level | step difference decorative surface DK, and the lower edge E is formed. Further, the tip of the lower edge E is bent to the indoor side to form a falling piece L, and the tip of the falling piece L is bent upward to form the insertion piece S. A water return piece W made of the piece S is formed. Further, the tip of the insertion piece S is bent indoors and folded downward to form a folded piece U.

Further, the upper end portion of the decorative surface K is bent to the outdoor side to form the rising piece T, the tip of the rising piece T is bent downward, the tip is bent to the outdoor side, and the tip is folded back upward. The fitting male part O is formed by bending the tip part along the rising piece T, and the tip part is bent upward and protruded so as to be the same surface as the decorative face K of the exterior material Y. The punching portion G is formed, the tip of the nail driving portion G is bent outward, and the tip is folded downward to form the tongue piece Z. In addition, t is a fitting groove part which consists of the decorative surface K, the starting piece T, and the fitting male part O.

  When the length from the stepped decorative surface DK to the tip of the insertion piece S is m, and the length from the tip of the fitting male portion O to the innermost end of the fitting groove t is n, m≈n. For this reason, as shown in FIG. 1, when the male and female are connected, the insertion piece S collides with the rising piece T, so that a gap C is formed between the water return piece W and the rising piece T. The

Furthermore, as shown in FIG. 1, when the male and female are connected, the protruding fitting female portion M has a height from the decorative surface K of the lower exterior packaging material Y, and there is also a space on the lower side. Therefore, at the lower end portion of the upper exterior material Y, the water that has flowed along the roof surface cuts well, and the retention of moisture, dust, and dust is prevented.

In addition to the good drainage due to the action of the protruding fitting female part M, the water return piece W composed of the falling piece L and the insertion piece S provides the water that has been transmitted without breaking, and the eaves side. It is also possible to prevent the water blown up from the inside of the fitting.

Further, since the gap C is formed inside the fitting by the rising piece L, the insertion piece S, and the rising piece T, water infiltration due to capillary action is also prevented.

When the width m1 between the decorative surface K and the lower edge E and the width of the fitting male portion O are n1, the relationship is m1≈n1 and m1> n1. For this reason, it can be constructed without play even after fitting.

In addition, since the lower end is formed by the protruding fitting female portion M and the water return piece W, the protruding fitting female portion M is thin and has a protruding shape, and is easily cut with scissors. For this reason, the lower end portion of the exterior material Y is easy to cut with scissors while ensuring a stepped height, so that processing during construction is facilitated.

The base α generally indicates a wooden base composed of a rafter, a field board, and a waterproof sheet. That is, the base α has a structure in which a base plate is laid on the rafter and a waterproof sheet (asphal roofing or the like) is disposed on the base plate. In addition, as base α, H-shaped steel, I-shaped steel, grooved steel, lightweight grooved steel, lip groove shaped steel, equilateral angled steel, unequal angled angled steel, square steel (square pipe), round steel (circular pipe), It may be a steel substrate using etc. Of course, in the case of roofs that are to be repaired while leaving the existing roofs, there is a structure in which a metal side roof, a metal roof tile roof, a new roof tile (colonial), a tile roof, etc. are formed under the existing roof. It becomes the ground α. Of course, a base α that does not form a waterproof sheet is also conceivable.

  What has been described above is only one example of the exterior structure according to the present invention, and the exterior material Y can be formed as shown in FIGS.
