The conventional building panel A is 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 considered to be caused by a difference in shrinkage that occurs after manufacture of the core material 3 made of the metal surface material 1 and the synthetic resin foam. 6 (b) to 6 (d), the metallic surface material 1 and the core material 3 of the base portion 1c of the deformed cover portion 7 are not bonded, and the deformation of FIG. In regard to the above, it is important to reinforce the cover portion 7 that is a deformable portion and that the innermost edge 8 and the core material 3 do not adhere.

  Therefore, in the building panel A according to the present invention, by forming a substantially T-shaped reinforcing plate B in the space 12 of the cover portion 7, the reinforcing piece BB of the reinforcing plate B and the back surface of the metal surface material 1 are formed. Are formed in contact with each other, and deformation of the cover portion 7 is prevented by the lower reinforcing piece B2 of the reinforcing plate B. Further, by forming the protruding piece B1 in contact with the innermost edge 8, adhesion of the protruding piece B1 and the innermost edge 8 by the core material 3 is prevented, and the cover portion 7 is brought into the indoor side due to contraction of the core material 3. Is also prevented.

  Further, in order to cope with the warp between the reinforcing plate B and the metal surface material 1, the width H of the space 12 shown in FIG. 5A is formed to be about 2 to 3 times the thickness of the metal surface material 1. The lower reinforcing piece B2 of the reinforcing plate B can be easily inserted.

  More specifically, as shown in FIG. 2A, the cover portion 7 is a portion surrounded by the lower end portion and the lower edge 6 of the metal surface material 1, and a space in which the lower reinforcing piece B <b> 2 of the reinforcing plate B is inserted. After the lower reinforcing piece B2 is formed in the space 12, the core material 3 is formed even if the core material 3 is formed in the space 12a and the space 12b separated by the reinforcing plate B in the cover portion 7. 3 may not be formed.

  The width X of the upper reinforcing piece B3 is set to be equal to or larger than the width of the portion where the metal surface material 1 is affected by the shrinkage of the core material 3 or the like.

Further, although the surfaces of the metal surface material 1 and the reinforcing plate B are visually flat, some unevenness exists, so that the reinforcing plate B and the metal surface material 1 are in contact with each other or partially. Have a gap 12a and a gap 12b.

  Further, as shown in FIGS. 4B and 4C (enlarged cross-sectional view of FIG. 4B), by forming an embossed pattern such as a concavo-convex pattern B4 on the reinforcing plate B, the gap 12a and the gap 12b are formed. Is formed. Of course, in this case, the uneven pattern B4 has the 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 metal surface material 1 with a working width of 600 mm as shown in FIG. A reinforcing plate B made of a Galvalume steel plate having a thickness of 0.35 mm and a width W of 65 mm is formed as shown in (c), and then the back surface of the metal surface material 1 is filled with a core material 3 made of polyisocyanurate foam. The back material 2 is formed of a 0.35 mm-thick color steel plate made of a galvalume steel plate and formed by sandwiching it as shown in FIG. 1, and has a total thickness of 50 mm.

In addition, if the length X of the upper reinforcing piece B3 is too short, deformation due to contraction of the core material 3 near the cover portion 7 cannot be prevented. Therefore, as a result of performing a test by changing the length width of the width X of the upper reinforcing piece B3 in the specification of the product in order to specify the length, X> 20 mm was effective.
