  Patent Documents 1 to 3 describe a heat insulating panel using an uneven corrugated metal plate as a surface material. However, Patent Document 1 is a heat insulating panel for building in which a foamed plastic board is formed on the back surface of a metal plate with wavy uneven portions, and Patent Document 2 is an outer wall in which an aluminum surface material is formed on the back surface of a corrugated steel sheet exterior material. There is a problem that the bending strength of the panel itself is inferior in both Patent Documents 1 and 2. Further, Patent Document 3 is such that a metal plate having a plurality of protrusions is attached to the outer surface of one metal shell of a panel material in which a heat insulating material is filled between metal shells, but a metal having a plurality of protrusions. The plate is simply attached and can be easily removed after construction. For this reason, the metal plate having a plurality of attached protrusions has poor wind pressure strength.

In order to solve such drawbacks, the present invention forms a decorative surface in which a plurality of continuous linear concavo-convex portions continuous in the longitudinal direction are formed, and a male-female connection structure is formed on the upper and lower ends of the decorative surface. and a metal facer has a cross heat material is filled between the metallic surface material of the decorative surface back surface of the concave-convex portion surface material formed from the back surface cover member made of bonded metal plate to cover the entire surface and the back surface member and forming integrally Te, the fixed surface reinforcement made of a metal plate formed into a wave shape in the longitudinal direction continuously form the fixed surface back side of the female coupling portion of the upper end, and an exterior member which is wider than the fixing surface Is to provide.

According to the exterior material which concerns on this invention, since a heat insulating material is not formed in the space of the convex part back surface of a metal surface material, the deformation | transformation by the secular change of a heat insulating material does not arise. Also, use a surface material formed from a metal surface material having a male-female connection structure on the upper and lower ends of the decorative surface, and a back surface cover material bonded so as to cover the entire uneven surface of the metal surface material. Thus, (2) the wind pressure strength of the exterior material can be greatly improved. (3) Fire resistance can be improved. (4) The strength can be improved by reinforcing the weak point of the bending strength of the uneven portion of the metal surface material. (5) A space can be reliably formed. (6) The back cover material in which the heat insulating material is bonded to the upper end portion of the metal surface material, the metal surface material, so that the heat insulating material filled in the male connecting portion and the female connection portion of the metal surface material is bonded. And the integration of the exterior material itself is strengthened. In addition, since the fixed surface reinforcing material is continuously formed on the back surface of the fixed surface, (7) deformation at the time of the wind pressure performance test from the corner portion of the fixed surface at the base portion of the fixed surface can be largely prevented, and the wind pressure performance is improved. Greatly improved. There are features and effects.

  As the material of the fixed surface reinforcing material 28, a metal thin plate such as iron, aluminum, copper, stainless steel, titanium, aluminum / zinc alloy plated steel plate, galbarium steel plate, enamel steel plate, clad steel plate, laminated steel plate (PVC steel plate, etc.), sandwich It consists of a steel plate (damped steel plate, etc.).

The fixed surface reinforcing material 28 is formed in order to improve the wind pressure resistance performance of the exterior material A, and is formed in a space surrounded by the heat insulating material 4 and the back surface material 3 on the back surface of the fixed surface 16. As shown in FIG. 11, when the conventional exterior material A receives a negative pressure F on the outdoor side in the wind pressure test, the fixed surface 16A is fixed with the fixed surface angle Y as a fulcrum. there were.

  As shown in FIG. 1, the fixed surface reinforcing member 28 is formed so as to protrude from the innermost surface of the fitting groove 17 toward the heat insulating material 4 by the width W. As shown in the figure, the deformation from the fixed surface angle Y portion due to the negative pressure during the wind pressure performance test is suppressed by shifting to the tip portion of the fixed surface reinforcing member 28, and the wind pressure performance is improved.

  As shown in FIG. 5, the fixing surface reinforcing member 28 is formed in a wave shape to suppress deformation in the width direction of the fixing surface 16 and by reinforcing the fixing surface 16, the fixing portion 16 is destroyed at the time of wind pressure resistance.

Integration with is strong. The lower end of the male connecting portion 5 has a four-layer structure in which the metal surface material 1a, the back surface cover material 2, and the back surface material 3 are integrally formed by caulking pieces 11a. Of course, if the end portion of the back cover material 2 is formed so that the metal surface material 1a is exposed on the male connection portion 5 side, the heat insulating material 4 is formed of the back cover material 2, the male connection portion 5, and the female connection portion. It will adhere | attach at three places with 6 parts, and integration of the metal surface material 1a used as the surface material 1, the back surface cover material 2, and the heat insulating material 4 will be strengthened further.

  In addition, the lower end part of the back surface cover member 2 is placed and adhered to the outdoor side of the upper surface 10 of the male connector 5, and the male connector 5 can be bonded to the heat insulating material 4 in the same manner as the female connector 6. It can also be a structure.

  The heat insulating material 4 is made of a synthetic resin foam such as polyurethane foam, polyisocyanurate foam, phenol foam, vinyl chloride foam, polyethylene foam, polystyrene foam, urea foam, and the like, and particularly when fire resistance is required. Is formed by mixing a stock solution of a resol type phenol, a curing agent, and a foaming agent, discharging the mixture onto the back surface side of the surface material 1 or the back surface material 3, and heating, reacting, foaming and curing. In addition, in the heat insulating material 4, lightweight aggregates (perlite grains, glass beads, gypsum slag, talc stone, shirasu balloon, aluminum hydroxide, etc.), fibrous materials (glass wool, rock wool, carbon fiber, Graphite etc. can be mixed to improve fire resistance and fire resistance. Of course, an inorganic material such as rock wool, glass wool, or ceramic wool may be used as the heat insulating material 4.
