  Patent Documents 1 to 5 describe a panel using a corrugated metal plate with an uneven strip as a surface material. However, Patent Documents 1 to 5 are building panels and metal sidings in which a foamed plastic board is formed on the back surface of a metal plate with a wavy uneven portion, and these are on the back surface of a metal surface material that is a surface material. When filling and molding foamable plastic resin, it is greatly increased in the width direction due to the synergistic effect of the uneven shape of the surface material and the flat back material due to foaming pressure, high temperature heat, shrinkage after demolding, etc. There was a risk of warping. Moreover, due to the uneven shape, the bending strength was inferior and the wind pressure resistance was adversely affected.

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. The metal surface material, a reinforcing net adhered to cover the entire uneven surface of the back surface of the decorative surface of the metal surface material, and the back material, and is insulated between the back surface and the back surface material of the metal surface material The insulation material is filled over the entire surface between the back surface and the back surface of the metal surface material including the reinforcement net, and the metal surface material, the reinforcement net, and the back material are integrated by the heat insulation material. The formed exterior material is provided.

  According to the exterior material according to the present invention, (1) the rigidity of the uneven decorative surface is reinforced, the weakness of the bending strength of the uneven portion of the metal surface material is reinforced, the rigidity of the exterior material itself is enhanced, and the wind pressure resistance performance Is improved. (2) The wind pressure strength of the exterior material can be greatly improved. (3) Since the reinforcing net is formed, the formation of the heat insulating material is not hindered. (4) In the case of a metal exterior material with an uneven surface and a flat back surface, the deformation due to the difference in shrinkage between the front surface and the back surface after the synthetic resin foam is formed is reinforced with a reinforcing net, and the flatness of the exterior material itself is maintained. I can do it. (5) The reinforcing net becomes a skeleton at the center portion of the exterior material, and warpage of the exterior material at the initial stage immediately after molding can be prevented. (6) Since the heat insulating material made of the synthetic resin foam penetrates between the metal surface material and the reinforcing net and can be bonded to each other in the gap between the reinforcing nets, the heat insulating material, the metal surface material and the reinforcing net are integrated. Will be strengthened. There are features and effects.
