Description

  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 an outer wall material in which a male-female connecting structure having a drop structure is formed on a side edge in the width direction, and the tip of the outer surface of the decorative surface of the outer wall material on the lower side. The present invention provides an outer wall material that protrudes in an L shape to form a protruding piece, and the protruding piece is partially bent to form an uneven portion.

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). 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, an upper surface 14 with the tip of the first waterproof piece 13 protruding upward, a top surface 14, and a fixed surface 15. A fitting groove 16 that fits into the insertion piece 9 formed in the above, a fitting piece 17 in which the tip of the upper surface 14 is bent downward, and a tip of the fitting piece 17 that protrudes downward. A female connecting portion 21 is formed from a two waterproof piece 18, a protrusion 19 formed at the tip of the second waterproof piece 18, and a recess 20 in which the second waterproof piece 18 is recessed.

  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 17 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 blows as shown by the arrow, the second waterproof piece 18 of the lower outer wall material A rotates around the tip of the waterproof piece 13 as shown by the one-dot chain line arrow A. However, the upper surface 14 is pressed against the insertion piece 9 of the upper outer wall material A as shown by the alternate long and short dash line a, and the engagement force is strengthened. Is to prevent peeling.

  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.
