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. An engaging groove is formed by the upper surface and the engaging groove, a male connecting portion having an uneven portion on the stepped decorative surface, and a decorative surface on the water-side end portion of the decorative surface. A fixed piece whose upper end protrudes further above the water and whose tip hangs downward, a first waterproof piece whose upper end is bent upward, and a fitting where the tip of the first waterproof piece protrudes above the water A fitting groove fitted to the insertion piece formed in a substantially U-shaped cross section from the piece, the fitting piece and the fixed surface, an upper surface where the tip of the fitting piece is bent to the water side, Forming the female connecting portion from the second waterproof piece projecting to the underwater side and the projection formed at the tip of the second waterproof piece, and the width from the innermost part of the engaging groove to the stepped decorative surface And the outer wall material which formed the width | variety from the front-end | tip of a processus | protrusion to the front-end | tip of a fitting piece in substantially the same length is provided.

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 width from the innermost part of the engaging groove to the stepped decorative surface and the width from the tip of the protrusion to the tip of the fitting piece to be substantially the same length, the protrusion fits inside the stepped decorative surface. Combined and concealed, it improves waterproofness, workability, wind pressure strength, and aesthetics. (5) By forming the concavo-convex portion, it is possible to form a wall with a profound feeling, sharpness and 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 as 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). The protruding piece 4a on the underwater side is bent upward in the drawing to form a concavo-convex part 4b to form a male connecting part 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. The female connecting portion 20 is formed from the second waterproof piece 18 and the protrusion 19 formed at the tip of the second waterproof piece 18.

  The width from the innermost part of the engagement groove 10 to 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, the height of the engagement groove 10 is h, and the fitting piece 14 is If the height from the protrusion 19 to the top surface is H, the height from the protruding piece 4a to the insertion piece 9 is t, and the height from the fitting piece 14 to the upper surface 17 is T, w≈W, t≈T, h≈H, w> W, t> T, h> H. Of course, when h <H (for example, H−h = about 0.5 to 3 mm), the protrusion 19 exhibits a further spring back effect in the engagement groove 10, and the engagement force, airtightness, and waterproofness are improved. It is a structure that can be improved.

  As described above, the relationship of w≈W, t≈T, and h≈H allows the protrusion 19 to be 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 upper outer wall material A 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.

In addition, since the uneven portion 4b is formed in a convex shape, the number of formed uneven portions 4b is an odd number, so that a convex portion (uneven portion) is formed at the center portion of the upper outer wall material A at the connecting portion of the left and right end portions. 4b), rainwater does not collect at the left and right connecting portions, and the waterproofness is improved.

  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 board in which these synthetic resin foams are sandwiched with sheet materials, Or made of gypsum board, cement board, calcium carbonate board, calcium silicate board, ceramic board, wood chip cement board, magnesium carbonate board, sizing 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.

  What has been described above is only one embodiment 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. 10 (a) to (c). it can.

  More specifically, FIGS. 7A to 7C to FIG. 10A to FIG. 10C show the outer wall material A in which the uneven portion 4b is variously deformed.
