[Problems to be solved by the device]

 In the conventional panel mounting structure of this type, the mounting of the panel on the base is fixed only on the back side of the recess, which is the joint, so for example, one panel mounted after construction If only the screws are damaged, the fasteners such as screws are hidden by the panel itself, so it is not possible to remove the screws from both the front and back sides of the panel. Had to remove all the panels from the panel in the corner of the building to the damaged panel being replaced.

In addition, in the panel joint structure disclosed in Japanese Utility Model Laid-Open No. 63-96144, screws are directly screwed into the panel to be fixed, so that the escape margin due to expansion and contraction due to heat cannot be removed. Bending occurs on the surface of the panel, cracks occur in the foam resin as the core material due to the different degrees of expansion and contraction due to heat of the front plate and the back plate, and the screw holes in the back plate where the screws are screwed widen. There was something that happened. Furthermore, in the panel joint structure of Japanese Utility Model Laid-Open No. Sho 63-96144, in order to use a mounting tool, and to fix the screw by screwing it from the surface of the base material, Since there is no choice but to reduce the thickness, it is unavoidable that the heat insulating property is deteriorated.

【Example】

 Hereinafter, the details of the invention will be described with reference to an embodiment in which a heat insulating panel is applied as an outer wall material as shown in the drawings. The heat insulation panel 1 is obtained by injecting a foam 13 made of an independent foaming synthetic resin between a front plate 11 and a back plate 12 made of a thin metal plate. The body 13 is adhered and integrated. At the side end along the longitudinal direction of the heat insulating panel 1, there are formed a joint recess 14 and a joint protrusion 15 which are fitted to each other. The thin portion 142 that continues from the bottom of the groove 141 of the joint recess 14 to the front surface in the attached state is longer than the thin portion 143 that continues to the back surface. The projection 151 of the joining convex portion 15 is to be fitted into the groove 141 of the joining concave portion 14, but is formed to be thin as much as the thickness of the mounting fitting 3 described later. The notch 152 on the front surface side that follows is formed longer than the notch 153 on the back surface side, and is formed so as to be separated from the surface plate 11 that follows the joining convex portion 15 and the surface plate 11 of the heat insulating panel 1 that is to be joined next. A small protrusion 152 is formed in the longitudinal direction on the front side of the strip 151 so as to be inscribed in the joint recess 14 of the subsequent heat insulating panel 1 when joined. The surface plate 11 covers the front surface in the mounted state, the top of the thin portion 143 continuing to the back surface of the joint recess 14, and the top of the protrusion 151 of the joint protrusion 15. The back plate 12 is provided only on the back surface of the joining concave portion 14 and up to the top of the protrusion 151 in the joining convex portion 15. This is mainly to prevent the foamed resin 13 from appearing on the front surface in the mounted state.

The heat insulating panel 1 having such a structure, which is formed by inserting the joining concave portion 14 and the joining convex portion 15 into the joining, joins the fitting 3 to the C-shaped channel material or the square pipe as the base material 2. It is designed to be attached via. This mounting bracket 3 is formed by connecting a holding portion 31 facing the heat insulating panel and along the front surface of the base material 2 and a mounting portion 33 obtained by bending so as to follow the side surface of the base material 2 in an L shape. On the holding portion side, a fitting piece 32 that fits into the joining convex portion 151 of the panel 1 is bent and protrudes.

That is, the fitting piece 32 is bent so as to cover the projection 151 from the notch 153 on the back surface side of the joining convex portion 15, and the tip thereof is located before the small projection 152. .. Therefore, the heat insulating panels 1 and 1 to be joined are held from the back plate 12 to the front plate 11. The mounting portion 33 is formed by bending the holding portion 31 at a right angle, has a hole 331 for holes, and hangs on the joint convex portion 15 of the heat insulating panel 1 to which the mounting metal fitting 3 is joined, and then the base material 2 is attached. It will be screwed and fixed by a screw 4 on the side surface.

In order to mount the heat insulating panel 1 having such a structure on the base material 2 by the mounting metal fitting 3, first, the fitting piece 32 of the mounting metal fitting 3 is hooked on the joint projection 15 of the heat insulating panel 1. The holding portion 31 is attached to the front surface of the base material 2 and the mounting portion 33 is fixed to the side surface of the base material 2 by screwing the screw 4 into the screw hole 331. The joint concave portion 14 of the heat insulating panel 1 is fitted so as to be inserted, and the joint convex portion 15 of the next heat insulating panel 1 is attached to the base material 2 by the same means, and this step is repeatedly attached.

FIG. 5 is a schematic view showing a procedure for removing the damaged heat insulating panel 1a in order to replace it. Remove the mounting bracket 3 at the bottom of the damaged heat insulating panel 1a by removing the screws 4 from both ends. (A) and (b), the damaged heat insulating panel 1a and the lower heat insulating panel 1 are pressed from behind to remove the fitting between the joint recess 14 and the joint protrusion 15 (c), and the damaged heat insulating panel 1a is pulled down and removed. Replacing would be the reverse of this procedure.

FIG. 6 is a perspective view showing another embodiment of the mounting member 3, in which a plurality of ribs are provided on the surface in order to increase the strength of the mounting member 3.

EFFECTS OF THE INVENTION The present invention has such a structure. Since the structure for joining the heat insulating panels is configured to be fixed on the side surface of the lower material, the screw heads as in the conventional example presented above are provided. The thickness of the panel is not reduced by that much and the heat insulation performance is improved. In addition, since the mounting part of the mounting bracket is on the side of the base material, if it is necessary to replace only one heat insulating panel after installation, remove the screws that are fixed from the inside and replace the heat insulating panel from the outside. It can be removed and a new insulation panel can be attached from the outside. In addition, the surface plate that covers the heat insulation panel covers from the front side in the mounted state to the top of the thin part that continues to the back surface of the joint recess and up to the top of the protrusion of the joint protrusion. If the tip of the holding part of the mounting bracket is configured to extend from the back plate of the joining convex part to the surface plate from the top of the thin part of the Effectively prevent peeling due to poor adhesion strength between the front and back plates and foamed resin as the core material and deterioration over time, and there is no clearance for the top plate due to thermal expansion caused by stopping with screws directly from the surface of the heat insulation panel. It is possible to prevent cracking of foamed resin as a core material and expansion of screw holes for stopping screws, which are caused by the bending caused by the deformation and the degree of expansion and contraction of the front and back plates.
