  The resin foam 3 of this embodiment is a phenol foam heat insulation panel made of a phenol resin foam, and is developed by the present applicant and disclosed in International Publication WO-00-1761 (Neoma Foam (registered trademark)). Can be created. This phenolic resin foam is a high-performance phenolic foam corresponding to one type according to the standard of phenolic foam insulation board specified in JIS A9511. It has high heat insulation performance and little dimensional change due to heat. It can be preferably used as a heat insulating material. In addition, the phenol resin foam can be preferably used in a portion where high combustion resistance is required because when the flame acts, the surface only carbonizes and does not spread suddenly and does not dissolve. .

  Layers of various face materials such as paper and resin can be provided on the front and back surfaces of the phenol resin foam, and the nonwoven fabric 3b is employed in this embodiment. Moreover, you may employ | adopt aluminum foil instead of the nonwoven fabric 3b, or may laminate | stack aluminum foil on the outer side of the nonwoven fabric 3b.

Phenolic resin foam according to the above techniques, and the phenol resin base portion, density and a bubble portion formed from a large number of fine bubbles are phenol foam of ^{10kg / m 3 ~100kg / m 3} , the fine bubbles Hydrocarbon is contained and the average cell diameter is in the range of 5 μm to 200 μm, and the cell walls of most of the fine cells are composed of a smooth phenol resin substrate surface. Despite the fact that the blowing agent is a hydrocarbon, it has a thermal conductivity comparable to that of conventional chlorofluorocarbon-based blowing agents, and there is no change over time in the thermal conductivity, resulting in a mechanical strength such as compressive strength. Excellent and improved brittleness.

  The heat insulating property in the phenol resin foam can be ensured by keeping the average cell diameter as small as 5 μm to 200 μm, preferably as small as 10 μm to 150 μm, and keeping the closed cell ratio as high as 80% or more. In addition, the phenol resin foam has high combustion resistance, and when the flame acts, the surface is merely carbonized and does not spread suddenly and does not melt. Furthermore, no toxic gas is generated.

For example, when the density of the phenol resin foam is set to 27 kg / m ³ , the thermal conductivity at 20 ° C. is 0.020 W / m · K, the compressive strength is 15 N / cm ² , and the thermal deformation temperature is 200 ° C. It is. As for the performance of the above-mentioned phenol resin foam, three types of extruded foamed polystyrene have thermal conductivity: 0.028 W / m · K, compressive strength: 20 N / cm ² , heat deformation temperature: 80 ° C., rigid urethane foam Type 2 No. 2 has sufficiently high performance compared with thermal conductivity: 0.024 W / m · K, compressive strength: 8 N / cm ² , heat distortion temperature: 100 ° C.

  For this reason, the resin foam 3 made of a phenol resin foam can exhibit substantially the same heat insulation performance and combustion resistance performance with a thickness of about 2/3 of conventional extruded polystyrene and rigid urethane foam. is there.

  The resin foam 3 can be made of various foamed plastics such as PVA (polyvinyl alcohol) and PP (Poly Propylene) other than the phenol resin foam.

  Similarly, a lightweight resin material can be used as the front panel 4, and in this embodiment, a material obtained by kneading stone powder into resin is used.

  According to the above configuration, the piercing piece 5b of the protrusion 5 fixed to the surface of the base material 1 is punctured on the back surface side of the resin foam 3 of the laminated exterior panel 2, whereby the own weight of the laminated exterior panel 2 is obtained by the protrusion 5. The laminated exterior panel 2 can be firmly and securely fixed to the base material 1 by the protrusions 5 and the adhesive 7.

  Further, since the width of the protrusion 5 in the horizontal direction (left and right direction in FIG. 1) along the surface of the base material 1 is wide, the load can be dispersed and the resin foam 3 is not locally damaged.

  Thus, there is no heat insulation defect of the resin foam 3, the fixture is not exposed on the surface side of the laminated exterior panel 2, the construction method can be shortened because it is a dry construction method, no pilot holes in the base material 1 are required, and screws It is possible to provide a method and structure for mounting a laminated exterior panel that can reduce noise such as stopping and improve panel mounting accuracy.

  The invention of the present application is not limited to the outdoors, but can be applied indoors if there is a ground for fixing the laminated exterior panel.

  As an application example of the present invention, it can be applied to an attachment method and an attachment structure for attaching a laminated exterior panel to a base material.
