  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 has a decorative surface in which a plurality of concave and convex portions are formed along the longitudinal direction, and a metal surface material in which a male-female connection structure is formed on the upper and lower ends of the decorative surface, The back surface of the decorative surface of the metallic surface material is formed from a back surface covering material that covers the entire concave and convex portion, and the back surface covering material has a plurality of through holes so as to communicate with the convex surface of the metallic surface material. An exterior material is provided which is integrally formed by filling a heat insulating material between a surface material and a back material in which holes are formed.

  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. Moreover, the surface material formed from the metal surface material which formed the male-female connection structure in the upper and lower ends of the decorative surface, and the back surface cover material adhered so as to cover the entire concave and convex portion of the metal surface material back surface is used. As a result, (2) 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. By forming a plurality of through holes in the back cover material so as to communicate with the convex back surface space of the metal surface material, (7) the heat insulating material filled with the metal surface material and the through hole portion It swells in the space at the through hole portion, and the integration of the back cover material and the heat insulating material of the surface material is strengthened. There are features and effects.

Integration with is strengthened. The male connecting portion 5 side 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 four 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.
