b, and the divided face materials 8a, 8b
Are integrated by joining face materials via a back plate 11.

The back plate 11 has an abutting portion (joining portion) 12 in a state where the divided face materials 8a and 8b are abutted against each other.
Is applied so as to cover it from the back side (heat insulating material side), and is fixed over the both surfaces 8 and 9 with an adhesive or a fixing tool such as a nail or a screw. The back plate 11 is preferably arranged on the back side that is not exposed on the surface of the face material 8.

As the divided face materials 8a and 8b, cut pieces (cut pieces) generated by cutting a face material of a specified size from an original plate such as OSB are used. The back plate 11 is preferably made of the same material as the plate material, for example, the face material, for example, a cut piece (cut material) of an OSB original plate.

The back plate 11 is preferably formed to be long and continuous along the joint 12 between the divided face materials 8a and 8b, but may be formed intermittently. The face material formed by joining the divided face materials 8a and 8b, that is, the face material 8 formed by joining the scrap materials is manufactured in advance by using the scrap materials and stocked, so that the face material for the heat insulating panel can be obtained. It can be appropriately used as a material.

As the heat insulating material 10, it is preferable to use a foamed heat insulating material, for example, a rigid urethane foam. The heat insulating material 10 may be a fixed heat insulating material formed in a predetermined shape in advance, but is a foam-filled heat insulating material formed by directly foam-filling between two facing face materials 8 and 9. Is preferred. When a fixed heat insulating material is used as the heat insulating material 10, the face materials 8, 9 may be fixed to both surfaces of the heat insulating material 10 with an adhesive.

On the other hand, when a foam-filled heat insulating material is employed as the heat insulating material 10, for example, a method of manufacturing a heat insulating panel as shown in FIG. 4 may be used. FIG. 4 schematically illustrates a batch-type manufacturing method for manufacturing heat-insulating panels one by one as an example of a method for manufacturing a heat-insulating panel. In the case of manufacturing a heat insulating panel, first, as shown in FIG. 4A, two face materials (at least one of which is a face material obtained by joining end materials) 8 and 9 are opposed to each other. A pair of end frames 13a, 13b and a pair of side frames 1 are provided between the two face materials 8, 9 so as to cover the four circumferences.
A jig 13 composed of 3c and 13d is assembled in a rectangular shape and sandwiched.

Next, as shown in FIG. 4 (b), the two face materials 8, 9 are pressed from the injection port 14 provided in the side frame 13d in a state where the two face materials 8, 9 are pressed so as not to expand. A molten heat insulating material (more precisely, a raw material of the heat insulating material) is injected into the space 9 to foam and fill. After curing and solidification of the heat insulating material, the jig 13
As a result, as shown in FIG. 4C, a heat insulating panel (roof panel) 2 in which a heat insulating material 10 is integrally provided between two face materials 8 and 9 is obtained. In this case, the two face materials 8 and 9 are integrally and firmly fixed to the heat insulating material 10 by the adhesive bonding force of the heat insulating material in the molten state.

As shown in FIGS. 1A and 1B, the roof panel 2 thus manufactured is a purlin material (including a purlin and a girder) 15 which is a structural material of a roof portion of a building. Mounted on the bridge. In this case, the divided face material 8,
9 are parallel to the structural material (purlin material) 15 and are not located on the structural material 15, but may be arranged to be orthogonal to the structural material 15. , May be located on the structural material 15. The roof panels 2 are mounted side by side on a structural member 15 as shown in FIG. In this case, in order to join the adjacent roof panels 2 and 2, it is preferable to adopt a joining structure as shown in FIG. 7, for example.

In this joint structure, the adjacent roof panels 2 are joined via a joint plate (joint material) 16 similar to the back plate 11. Adjacent roof panel 2,
A groove 17 for inserting the bonding plate 16 between each of the face materials 8 and 9 and the heat insulating material 10 is formed in the abutting portion 2, and the bonding plate 16 is inserted across both opposing grooves 17. By fixing the face materials 8, 9 and the joining plate 16 with an adhesive or a fixing tool, the roof panels 2, 2 can be easily joined to each other.

According to the roof panel 2 having the above structure, the heat insulating material 10 is provided between the two facing face materials 8 and 9, and at least one of the face materials 8 has a plurality of faces. The surface materials 8a and 8b are divided into a plurality of surface materials 8a and 8b, and the divided surface materials 8a and 8b are previously integrated by joining the surface materials to each other via the back plate 11, so that the divided surface materials 8a and 8b are divided. For example, if a scrap of an original plate such as OSB is used as 8b, the yield of the original plate can be improved and the surface material can be effectively used. In addition, the use of the remnants can reduce the manufacturing cost of the heat insulating panel, reduce the cost of disposing of the remnants, and save the forest resources.

FIG. 2 shows another example of a roof panel.
The roof panel 2 is provided with a heat insulating material 10 between two facing face materials 8 and 9.

The other structure is the same as that of the above-described embodiment, and the description is omitted. According to the roof panel 2, by forming the opposing double-sided members 8 and 9 by using the scraps, it is possible to further effectively use the surfaced members and reduce the manufacturing cost, and to reduce the manufacturing cost. Since the joints 12a and 12b in FIG. 9 are arranged so as to be shifted from each other, concentration of stress on the joints 12a and 12b can be prevented, and the strength can be improved.

The heat insulating material 10 is foam-filled from the heat insulating material injection nozzle 21 between the two surface materials 8 and 9 in the process in which the upper and lower surface materials 8 and 9 are conveyed and moved in the arrow direction. ing. Downstream of the position C, a cutter or the like is provided for individually separating the heat insulating panels conveyed in a connected state via the heat insulating material formed continuously. According to this manufacturing method, the heat insulating panel 2 can be manufactured continuously.

In the above embodiment, an example is shown in which the present invention is applied to a roof panel, but the present invention is also applicable to a wall panel 3, a floor panel 4, and the like. FIG. 8 shows an example of a joining structure for joining adjacent wall panels. In this joint structure, adjacent wall panels 3 and 3 are joined via a frame material or a pillar material (for example, a two-by-four material) 22. A groove 23 for fitting the column member 22 to the heat insulating material 10 between the double-sided members 8 and 9 is formed in the abutting portion of the adjacent roof panels 3, 3. By fitting the column members 22 and fixing the face members 8, 9 and the column members 22 with an adhesive or a fixing tool, the wall panels 3, 3 can be easily joined to each other. As for the roof panel 2, it is preferable that the joints 12 a and 12 b between the face materials of the two face materials 8 and 9 are not located at a symmetric position with the heat insulating material 10 interposed therebetween.
