  The present invention relates to an outer wall material having an unprecedented appearance and having workability, a waterproof function, a heat insulating function, and the like.

  In general, many outer wall materials obtained by processing a metal plate material by roll molding, press molding or the like have been put on the market, and the shape thereof is a so-called drop structure. (For example, refer to Patent Documents 1 to 5).

Japanese Patent Laid-Open No. 11-172848 Japanese Patent Laid-Open No. 11-172892 JP-A-11-210149 JP 2002-220908 A JP 2002-235423 A

  Although Patent Documents 1 to 5 have a drop-in structure, the fitting structure is simple and there are weak points in engagement force, wind pressure strength, airtightness, and the like.

  In order to solve such drawbacks, the present invention provides a substantially horizontal decorative surface, a stepped decorative surface that protrudes downward from the top of the decorative surface in an L-shape, and a stepwise decorative surface and an inner side along the decorative surface. The uppermost surface protruding from the top, the innermost piece protruding downward from the upper end, the insertion piece protruding the tip of the innermost piece downward, and the upper surface, the innermost piece and the insertion piece. A male coupling portion formed with a concave and convex portion projecting to the underwater side on the stepped decorative surface, and a water-side end portion of the decorative surface The upper end portion of the decorative surface further protrudes to the upper side of the water, the fixed piece with the tip hanging downwards, the first waterproof piece with the lower end of the fixed piece bent upward, and the tip of the first waterproof piece on the water The fitting piece protruding to the side, the fitting groove formed in the substantially U-shaped cross section from the fitting piece and the fixed surface, and the tip of the fitting piece bent downward. The female connecting portion is formed from the upper surface, the second waterproof piece protruding from the upper end of the upper surface, and the protrusion formed at the distal end of the second waterproof piece, and a step from the innermost part of the engaging groove. The outer wall material is provided so that the width of the decorative surface to the uneven portion and the width from the tip of the protrusion to the tip of the fitting piece are substantially the same length.

According to the outer wall material according to the present invention, (1) waterproofness can be maintained even when the fitting piece formed with the first waterproof piece and the second waterproof piece drops the outer wall material. (2) When the upper outer wall material is applied to the lower outer wall material, the second waterproof piece of the lower outer wall material contacts the upper surface of the upper outer wall material, and the second waterproof piece always springs in the engagement groove. It exhibits a back effect and improves waterproofness and airtightness. (3) The formation of the second waterproof piece cancels the opposing forces in the connecting portion between the outer wall materials, so that the outer wall is not broken unless the outer wall material is destroyed or the fixture formed on the fixed piece falls off the base. The material is not peeled off by the wind. (4) By forming the concavo-convex portion, it is possible to form a wall having a profound feeling, sharpness and an unprecedented appearance. There are features and effects.

  The outer wall material according to the present invention will be described in detail below with reference to the drawings. 1 (a) to 1 (c), 2 (a), and 2 (b) are explanatory views showing a typical example of an outer wall material A made of a metal outer wall material B, a backing material C, and a sheet D. FIG. 2A is an end view of the aa portion of FIG. 2A, FIG. 1B is a cross-sectional view of the aa portion of FIG. 2A, and FIG. 1C is a cross-sectional view of FIG. b section sectional drawing, FIGS. 3-6 is explanatory drawing which shows the construction state of the outer wall material A. FIG. In the figure, α indicates a base, and β indicates a fixture such as a nail.

  The base α indicates a wooden base composed of a casing 1, a trunk edge 2, and a waterproof sheet 3 as shown in FIGS. That is, it is a base α having a general structure in which a trunk edge 2 is laid on the casing 1 and a waterproof sheet 3 is disposed on the trunk edge 2. 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 is also possible to use a steel base using, for example. Of course, when the existing wall is peeled off to make the base α, or when the existing wall is repaired as the base α as it is, the existing wall structure in which the existing wall (not shown) is formed on the base α is the base α. It will be. Of course, the base α on which the waterproof sheet 3 is not formed may be used.

  The metal outer wall material B is formed by roll molding, press molding, extrusion molding, 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.), for example. . Of course, instead of the metal outer wall material B, the surface material of the outer wall material A may be formed of a ceramic material, a synthetic resin material (plastic), or the like.

  More specifically, the metal outer wall material B is in the form of a long plate, and as shown in FIGS. 1A to 1C, the substantially horizontal flat decorative surface 4, the back surface 5, and the tip of the decorative surface 4 are formed. A stepped decorative surface 6 projecting downward in an L shape, an upper surface 7 projecting inward along the stepped decorative surface 6 and the decorative surface 4, an innermost piece 8 projecting the tip of the upper surface 7 downward, A substantially U-shaped engagement groove 10 is formed from the insertion piece 9 with the tip of the back piece 8 projecting under water, the upper surface 7, the innermost piece 8 and the insertion piece 9, and is engaged with the upper surface 7. The insertion gap 11 is formed by the groove 10, and the stepped decorative surface 6 has a protruding piece 4a and the decorative surface 4 as shown in FIGS. 1 (b), (c), 2 (a) and 2 (b). In the drawing, the protruding piece 4a on the underwater side is bent to the underwater side to form a concavo-convex portion 4b to form the male connecting portion 12.

  Further, as shown in FIGS. 1A to 1C, a fixed piece in which the upper end portion of the decorative surface 4 protrudes further to the upper water side and the tip hangs down to the lower water side at the upper surface portion of the decorative surface 4. 15, a first waterproof piece 13 with the lower end of the fixed piece 15 bent upward, a fitting piece 14 with the front end of the first waterproof piece 13 protruding upward, a cross section from the fitting piece 14 and the fixed surface 15. A fitting groove 16 that fits into the insertion piece 9 formed in a substantially U-shape, an upper surface 17 in which the tip of the fitting piece 14 is bent to the water side, and a tip of the upper surface 17 protrudes to the water side. A female connecting portion 21 is formed from the second waterproof piece 18, the protrusion 19 formed at the tip of the second waterproof piece 18, and the recess 20.

  The width from the innermost part of the engagement groove 10 to the uneven portion 4b of the stepped decorative surface 6 is w, the width from the tip of the protrusion 19 to the tip of the fitting piece 14 is W, and from the tip of the insertion piece 9 to the uneven portion 4b. X, the width between the tip of the engagement piece 14 and the recess 20 is X, the height from the fitting piece 14 to the top surface of the projection 19 is T, and the height from the protruding piece 4a to the insertion piece 9 Where t is the height of the upper surface 17 from the fitting piece 14, and W≈W, x≈X, t≈T≈H, and w> W, x> X, t> T, and t> H. . Of course, when t <T (for example, Hh = about 0.5 to 3 mm), the protrusion 19 exhibits a further spring back effect in the connecting portion, and the engagement force, airtightness, and waterproofness can be further improved. It becomes a structure.

  As described above, with the relationship of w≈W, x≈X, t≈T≈H, the projections 19 are fitted inside the stepped decorative surface 6 and concealed when the outer wall materials A are connected to each other. It improves waterproofness, workability, wind pressure strength and aesthetics.

  The stepped decorative surface 6 is connected to the second waterproof piece 18 as shown in FIGS. That is, the stepped decorative surface 6 collides with the tip end portion of the second waterproof piece 18 during fitting, and the second waterproof piece 18 is deformed by its own springback by the collision force and is firmly connected.

  The first waterproof piece 13 is a part that functions as a part of the fitting piece 14 while adding a waterproof function by bending upward.

  The second waterproof piece 18 prevents rain and wind blowing on the outer wall material A from directly blowing onto the upper surface 7 of the outer wall material A, and prevents the outer wall material A from being peeled off by the wind. That is, as shown in FIG. 6, when the wind is blown as shown by the arrow, the second waterproof piece 18 of the lower outer wall material A is centered on the tip of the first waterproof piece 13 as shown by the dashed-dotted arrow A. However, conversely, the engaging piece 14 presses the insertion piece 9 of the outer wall material A on the upper stage as shown by the alternate long and short dash line a, and the engaging force is strengthened. This prevents the material A from being peeled off by the wind.

  In this way, since the opposing forces are offset within the connecting portion between the outer wall materials A, the outer wall material A is not broken unless the outer wall material A is broken or the fixture β formed on the fixing piece 15 falls off the base α. Is not peeled off by the wind.

  The second waterproof piece 18 has a U-shaped groove formed by projecting the tip of the waterproof piece 13 to the underwater side, and wind and rain that is about to enter the groove is rotated in the opposite direction and discharged. And formed to improve waterproofness.

  The protruding piece 4a is a part that forms a concavo-convex part 4b by being partially bent to improve the design. Moreover, the uneven | corrugated | grooved part 4b can be formed by simple process which only bends the protrusion piece 4a (press process etc.) for the metal outer wall material B processed by the general roll forming.

  The backing material C is a synthetic resin foam such as polyurethane foam, polyisocyanurate foam, phenol foam, vinyl chloride foam, polyethylene foam, polystyrene foam, urea foam, or a composite plate in which these synthetic resin foams are sandwiched with a sheet material, Or made of gypsum board, cement board, calcium carbonate board, calcium silicate board, ceramic board, wood chip cement board, magnesium carbonate board, sieving board, sieving insulation board, plywood, etc., or a composite board of these. It is.

Sheet D is a metal material or asbestos paper, kraft 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 Or a laminate of two or more types, or a sheet that has been subjected to waterproof treatment or flame retardant treatment.

  The above description is only one example of the outer wall material according to the present invention, and the outer wall material A may be formed as shown in FIGS. 7 (a) to (c) to FIGS. 14 (a) to (d). it can.

  More specifically, FIGS. 7A to 7C to 14A to 14D show the outer wall material A in which the uneven portion 4b is variously deformed.
