And are integrally molded.

Further, in this embodiment, the foam-molded heat insulating material 2 is foam-molded using polystyrene, and the structural face material 3 is formed of a so-called wafer-bore obtained by press-molding a wood chip with an adhesive.ド.

As shown in FIG. 4, the roof panel 1 in the present embodiment includes an indoor roof panel 101 and an eaves roof panel 10.
2, the indoor roof panel 101 and the eaves roof panel 102 are formed such that the panel thickness of the indoor roof panel 101 is larger than the panel thickness of the eaves roof panel 102. Is the same. At both end faces in the girder direction of the indoor roof panel 101, as shown in FIG. 2, the end faces of the foam-molded heat insulating material 2 are each half the thickness of the side piece 4 as compared to the both end faces of the both face pieces 3 for structure. The first recessed portion 5 is formed by being formed by being cut only.

Similarly, at both end surfaces of the eaves roof panel 102 in the girder direction, as shown in FIG. 3, the end surfaces of the foam-molded heat insulating material 2 are thicker than the end surfaces of both structural surface materials 3. The second concave portion 6 is formed by being cut and formed by half the size of the hole.

In the present embodiment, the side member 4 is formed of a structural lumber. The side member 4 has an indoor portion corresponding to the height L1 of the first concave portion 5 and an eave portion corresponding to the height L1. The second recess 6 is formed to have a height that matches the height L2.

[0012] At both end surfaces of the indoor roof panel 101 in the gradient direction, the end surfaces of the foam-molded heat insulating material 2 are notched and molded by a predetermined dimension from both end surfaces of both structural surface materials 3. A third concave portion 7 is formed, and a joining material 8 formed in accordance with the dimension in the row direction of the indoor roof panel 101 is fitted and fixed in the third concave portion 7. .

Further, at both end surfaces of the eaves roof panel 102 in the gradient direction, the end surfaces of the foam-molded heat insulating material 2 are cut off by a predetermined dimension from both end surfaces of the both structural surface materials 3 and formed. Thereby, the fourth recessed portions 9 are formed, and the joining material 10 formed in conformity with the girder dimension of the eaves roof panel is fitted and fixed in the fourth recessed portion 9 on the indoor side. At the same time, the eaves material 11 continuous in the row direction is fitted and fixed in the fourth recess 9 on the eave tip end side. In the present embodiment, the joining material 8,
10 and eaves material 11 are also formed by structural lumber.

When installing the roof panel, the indoor roof panel 101 is first mounted and fixed between the roof beam 12 and the outer wall panel 13 as shown in FIG. In addition, on the outer wall panel 13, a gradient adjusting member 14 that matches the gradient of the roof is arranged. One end of the indoor roof panel 101 is set so as to be located at the outer end of the gradient adjusting member 14 as shown in FIG.

Next, as described above, the indoor portion has the height dimension of the first recessed portion 5 and the eaves portion has the height dimension matched with the height size of the second recessed portion 6. The indoor part of the material 4 is fitted and fixed to the first concave part 5 of the indoor roof panel 101. In addition, the length of the indoor part of the side member 4 is set to be equal to or longer than the length of the eaves part, and the side member 4 is positioned at the outer end of the slope adjusting member 14 as shown in FIG. It is assumed that the height dimension of the eaves 4 is reduced and the eaves are formed so as to start.

In this manner, the indoor roof panel 10
1 and each indoor roof panel 10 as shown in FIG.
A screw nail 16 is driven into the frame member 15 of the outer wall panel 13 from the upper surface of the panel 1, and the side member 4 and the outer wall panel 13 are tightly fastened by a pivoting stopper 17.

In the third recessed portion 7 of each indoor roof panel 101, a joining material 8 formed so as to conform to the dimension in the row direction of the indoor roof panel 101 is fitted and fixed. The joining material 10 formed in conformity with the dimension of 102 in the row direction is fixed with its upper end aligned with the corresponding joining material 8.

Then, as shown in FIG. 4, each eaves roof panel 102 is inserted into the eaves portion of the pair of side members 14 so that the corresponding second recessed portions 6 are fitted into the eaves roof panel 102, and the indoor side is installed. Each eaves roof panel 102 is fixed in a state where the fourth concave portion 9 is fitted to the joining material 10. Finally, a long eaves material 11 may be fitted and fixed in each of the fourth recesses 9 on the eaves side.

In this embodiment having such a configuration,
Since the foam-molded heat insulating material 2 can be structurally functioned as a core material by being integrated with the structural face material 3, it is excellent in heat insulation performance and sound insulation performance. There is no need to provide heat insulation or soundproofing materials in the building, which is extremely reasonable and economical.

Further, since each component in this embodiment can be manufactured in advance at a factory,
At the work site, these members can be simply joined together, and complicated eaves construction is not required for carpenters or other specialized technicians.
It can be done safely and quickly and is ideal for the modern era of a shortage of skilled workers. In addition, since the structural panel 3 is applied to the roof panel 1 on the upper and lower sides in advance, after constructing the roof, secondary carpentry work is not required, and the roof and eaves can be finished immediately. Therefore, labor saving of construction becomes possible.

However, the present invention is not limited to the above-described embodiment, but includes the foamed heat insulating material 2 and the structural face material 3.
Needless to say, various modifications can be made without departing from the gist of the present invention, for example, the material of the constituent members such as can be appropriately made materials having the same performance in addition to the above embodiment. Absent.

[0022]

[Effect of the Invention] The present invention is configured as described above.
The following effects can be obtained. (1) The foam-molded heat insulating material, by being integrated with the structural face material, can structurally function as a core material and has excellent heat insulating performance and soundproofing performance. There is no need to separately provide heat insulation and sound insulation, which is extremely reasonable and economical. (2) Since each component can be factory-produced in advance, it is only necessary to join these components at the site, and complex eaves construction can be performed by specialized skills such as carpenters. It can be done safely and quickly even if it is not a mechanic. (3) Since the roof panels are pre-attached with structural panels on the top and bottom, secondary construction carpentry work is not required after the roof is constructed, and the roof and eaves can be finished immediately. Thus, labor saving in construction is possible.
