A conventional building panel A is as shown in FIG. 6A, and the space 12 of the cover portion 7 is filled with the core material 3 made of a synthetic resin foam. In this case, the core material 3 contracts as shown by arrows in FIGS. 6B to 6E, and the cover portion 7 warps to the outdoor side as shown in FIG. 6B (warpage). As shown by a dotted arrow in FIG. 6C, the root portion of the cover portion 7 is partially recessed in the indoor side (dent), as shown by a dotted arrow in FIG. ) As shown in the figure (warp) and (c) figure (dent), it dents or warps outdoors, or the cover part 7 warps indoors as shown by the dotted arrow in FIG. ) Although not shown in the drawings, the same deformation may occur even when the core 3 is not formed in the cover portion 7.

  This is thought to be caused by a difference in shrinkage that occurs after the production of the core material 3 made of the metal surface material 1 and the synthetic resin foam. From this, regarding the deformation of FIGS. 6B to 6D, the surface material 1 and the core material 3 of the base portion 1c of the cover portion 7 to be deformed are not adhered, and the deformation of FIG. It has been found that it is important to reinforce the cover part 7 which is a deformed part.

  Therefore, in the building panel A according to the present invention, the reinforcing plate B is formed in the space 12 of the cover portion 7 so that the outdoor side surface of the reinforcing plate B and the back surface of the surface material 1 are bonded by the core material 3. In addition, the cover 7 is prevented from being deformed by the reinforcing plate B. Further, the width H of the space 12 is formed to be about 2 to 3 times the thickness of the surface material 1 to facilitate the insertion of the reinforcing plate B and to cope with the warp of the reinforcing plate B and the surface material 1. is there.

  More specifically, the cover portion 7 is a portion surrounded by the lower end portion 6 and the lower edge 6 of the surface material 1, has a space 12 into which the reinforcing plate B is inserted, and the reinforcing plate B is formed in the space 12. Later, the core material 3 or the like may or may not be formed in the space 12a and the space 12b formed by the reinforcing plate B in the cover portion 7.

  That is, at least the protruding piece B2 of the reinforcing plate B, which is the length X portion from the innermost edge 8 to the tip of the reinforcing plate B, is in contact with the back surface of the surface material 1.

  As shown in the figure, when the reinforcing plate B is formed up to the innermost part of the space 12, the relationship between the width W of the reinforcing plate B and the depth W1 of the space 12 is W> W1. Further, in the case of W ≦ W1, the reinforcing plate B is formed up to the middle of the space 12, and the reinforcing plate B protrudes from the innermost edge 8 toward the core member 2 to form the protruding piece B2. The protrusion width X is equal to or greater than the width of the portion where the surface material 1 is affected by the contraction of the core material 3 or the like.

Furthermore, although the surface of the surface material 1 and the reinforcing plate B is a flat plate in appearance, since there are some irregularities, the reinforcing plate B and the surface material 1 are in contact with each other, or are partially voids 12a, It has a gap 12b. Further, in the figure, due to the shape of the surface material 1, the core material 3 is not formed in the gap 12a but becomes a space, and the core material 3 enters the gap 12b, and the core material enters the gap 12b as shown in FIGS. 3 is filled.

Of course, the effect of preventing the deformation of the cover portion 7 is similarly exhibited whether or not the core material 3 is present in the gaps 12a and 12b formed by the reinforcing plate B in the cover portion 7. Is.

  Further, as shown in FIGS. 4B and 4C (enlarged cross-sectional view of FIG. 4B), the reinforcing plate B is formed with an embossed pattern such as an uneven pattern B1. As a result, the gap 12a and the gap 12b may be formed. Of course, in this case, the uneven pattern B1 has an effect of further preventing the deformation of the cover portion 7 in order to improve the strength of the reinforcing plate B.

P is a packing material, which is formed to improve fire resistance, waterproofness, airtightness, and the like. For example, typical and elastic packing material P is generally commercially available such as polyvinyl chloride, chloroprene, chlorosulfonated polyethylene, ethylene propylene, asphalt impregnated polyurethane, EPM, EPDM, and the like. is there. Further, as the curable packing material P (sealing material), silicone type (reaction curable type, moisture curable type), modified silicone type (reactive curable type), polysulfide type (reactive curable type), polyurethane type (reactive curable type, Moisture curable type), SBR type (dry curable type), acrylic type (dry curable type), etc. are mainly useful as functions of waterproofing material, airtight material and the like. Of course, flame retardants such as inorganic materials or flame retardants such as ammonium polyphosphate, aluminum hydroxide, phenol resin particles, carbon black, graphite (foamed and non-foamed) having fire resistance and fire resistance in these components. A fire-resistant packing material mixed with a material may be used.

  As the building panel A according to the present invention, for example, a 0.5 mm-thick color steel plate made of a galvalume steel plate is formed as the surface material 1 with a working width of 600 mm as shown in FIG. As shown in c), a reinforcing plate B made of a galbarium steel plate having a thickness of 0.35 mm and a width W of 65 mm is formed, and then the back surface of the surface material 1 is filled with a core material 3 made of polyisocyanurate foam. As shown in FIG. 1, a 0.35 mm-thick color steel plate made of a galbarium steel plate is sandwiched to form a total thickness of 50 mm.

In addition, when the protrusion length of the length X from the innermost edge 8 to the front-end | tip of the reinforcement board B is small, the deformation | transformation by the core material 3 contraction of the cover part 7 vicinity cannot be prevented. Therefore, as a result of performing a test while changing the width of the reinforcing plate B in accordance with the specifications of the product in order to specify the length, X> 20 mm was effective.
