Description

  The present invention relates to a building panel having workability unprecedented as a building panel and having improved waterproofness, airtightness, heat insulation and the like.

  In general, many architectural panels obtained by processing metal plate materials by roll molding, press molding, and 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 are drop structures, the fitting structure is simple and there are weak points in engagement force, airtightness, and the like.

  In order to solve such drawbacks, the present invention provides a first waterproof piece projecting outward from the upper end of the decorative surface, a fitting piece projecting the tip of the first waterproof piece upward, and a first waterproof piece. A second waterproofing piece that forms a concave strip that protrudes downward and has a concave recess, and a fixed piece that protrudes further upward from the upper end of the decorative surface. A building panel having an engagement groove formed from the decorative surface, the innermost piece, and the insertion piece. .

  According to the building panel 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 building panel. (2) When the upper building panel is installed on the lower building panel, the second waterproof piece of the lower building panel contacts the upper surface of the upper building panel, and the second waterproof piece is always engaged. A spring back effect is exhibited in the groove, improving waterproofness and airtightness. (3) The formation of the second waterproof piece cancels the opposing forces in the connecting portion between the building panels, so that the building panel is destroyed or the fixture formed on the fixed piece does not fall out of the ground. The building panel is not peeled off by the wind. There are features and effects.

  Hereinafter, a building panel according to the present invention will be described in detail with reference to the drawings. FIG. 1 is an explanatory view showing a typical example of a building panel A made of a metal building panel B and a backing material C, and FIGS. 2A and 2B are explanatory views showing a construction state of the building panel A. FIG. is there. 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 the casing 1, the trunk edge 2, and the waterproof sheet 3 as shown in FIGS. 2A and 2B at the time of new construction. 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 repairing an existing wall as it is, an existing wall structure in which an existing wall (not shown) is formed on the base α is the base α. Of course, the base α on which the waterproof sheet 3 is not formed may be used.

  The metal building panel B is formed by roll forming, press forming, extrusion forming, or the like, for example, a metal plate (color steel plate, copper plate, aluminum plate, titanium plate, stainless steel plate, sandwich steel plate, clad steel plate, etc.). is there. Of course, as the surface material of the building panel A, the ceramic building material B or the synthetic resin material (plastic) may be formed instead of the metal building panel B.

  More specifically, the metal building panel B is in the form of a long plate. As shown in FIG. 1, the decorative surface 4, the back surface 5, and the tip 6 of the decorative surface 4 are arranged along the decorative surface 4. The upper surface 7 protruding upward, the innermost piece 8 protruding the tip of the upper surface 7 outward, the insertion piece 9 protruding the tip of the innermost piece 8 downward, the upper surface 7 and the innermost piece 8 A substantially U-shaped engaging groove 10 is formed from the insertion piece 9, and an insertion gap 11 is formed by the upper surface 7 and the engaging groove 10 to form a male connecting portion 12.

  Further, as shown in FIG. 1, the upper end portion of the decorative surface 4 is provided with a fixed piece 15 that protrudes further upward from the upper end portion of the decorative surface 4 and an upper end of the decorative surface 4 (lower end of the fixed piece 15). A first waterproof piece 13 projecting in the direction, an upper surface 14 projecting upward from the tip of the first waterproof piece 13, and the insertion piece 9 formed in a substantially U-shaped cross section from the upper surface 14 and the fixing surface 15 A fitting groove 16 to be mated, a fitting piece 13a in which the tip of the upper surface 14 is bent downward, and a second waterproofing formed with a recess 13c protruding in a concave shape while projecting the tip of the fitting piece 13a downward. The female connection part 17 is formed from the piece 13b and the waterproof protrusion 13d formed at the tip of the second waterproof piece 13b.

  The 1st waterproof piece 13 is a part which functions also as a part of fitting piece 13a while adding a waterproof function by bending upward.

  The second waterproof piece 13b prevents rain and wind blowing on the building panel A from directly blowing onto the upper surface 7 of the building panel A, and prevents the building panel A from being peeled off by the wind. That is, as shown in FIG. 3, when the wind is blown as shown by the arrow, the second waterproof piece 13b of the lower building panel A is centered on the tip of the waterproof piece 13 by the wind as shown by the one-dot chain line arrow A. A force that lifts up so as to rotate works, but conversely, a force that presses down the insertion piece 9 of the upper building panel A as shown in a dashed line arrow a on the upper surface 14 works and the engaging force is strengthened. This prevents A from being peeled off by wind.

  In this way, since the opposing forces are offset within the connecting portion between the building panels A, the building panel A is destroyed unless the building panel A is destroyed or the fixture β formed on the fixing piece 15 falls off the base α. The panel A is not peeled off by wind.

The second waterproof piece 13b protrudes downward from the tip of the first waterproof piece 13 to form a space γ having a U-shaped cross section, and the wind and rain that is about to enter the space γ is rotated in the opposite direction. It is formed to improve waterproofness.

The recess 13c forms a space by recessing the second waterproof piece 13b in a concave shape, and prevents rainwater from entering the inside due to a capillary phenomenon.

Backing C waterproof material, heat insulating material, sound absorbing material, a cushioning material, fireproof material, condensation preventing material, Ru der functions as such.

What has been described above is only one example of the building panel according to the present invention, and the building panel A is formed as shown in FIGS. 4 (a) to 4 (e) to 9 (a) to 9 (c). it is also possible.

  It can also be used as a roofing material and has a wide range of use.
