The heat-insulating roof material A is a material in which the heat-insulating material 3 is filled between the front metal plate 1 and the back metal plate 2, and extends in the width direction of the heat-insulating roof material A (a direction orthogonal to the eaves direction). Mountains 4 and 4 are formed at an interval along the entire length of the eaves. The connecting portion 8 is formed on one side of the heat insulating roofing material A, and the connected portion 9 is formed on the other side.

The connecting portion 8 and the connected portion 9 are formed in a semi-mountain shape, the connecting portion 8 is formed by extending only the metal plate 1, and the connected portion 9 is provided with the heat insulating material 3 on the back surface of the metal plate 1. Make it exist. A hook-shaped connecting piece 10 is formed at the tip of the connecting portion 8 by being bent downward over the entire length. A recess 5 is formed in the connected portion 9 over the entire length. Thus, the drainage space 11 is formed when the connecting piece 10 is locked to the connected portion 9.

The heat-insulating roofing material A has a stepped portion 7 that is linear in the peak portion 4, the flat portion 6, the connecting portion 8, and the connected portion 9 at intervals in the ridge eaves direction. Are formed.
The step portion 7 has a substantially equal height between the flat portion 6 and the peak portion 4. A recess 5 for accommodating the upper part of the mountain part 4 is formed on the back side of the mountain part 4 along the entire length of the eaves. Thus, the surface of the heat-insulating roofing material A can be formed into a lattice shape by the peaks 4 extending over the entire length in the direction of the eaves and the steps 7 orthogonal to the peaks 4, so that a sense of small splitting can be obtained. In this case, the strength of the heat-insulating roofing material A can be increased by the rib effect of the peak portion 4 and the step portion 7. In addition, when the connecting piece 10 is connected to the connected portion 9, as shown in FIG. 4, a drainage space 11 can be formed between the connecting piece 10 and the connected portion 9, and rain water flows from the connecting portion to the capillary. The phenomenon can be effectively prevented from entering. In the figure, P is a packing for watertightness and airtightness of the connecting portion.

FIGS. 6 and 7 show a method and an apparatus for manufacturing the heat-insulating roofing material A. The heat-insulating roofing material A is manufactured independently of a single product. The front and back metal plates 1 and 2 are press-formed in advance, the back metal plate 2 is placed on the lower base 17, and the front metal plate 1 is magnetically held on the upper table 18 by an electromagnet or the like and held. Then, the upper table 18 is raised through the lifting means 19, and the side jig 2 is
Are arranged, the upper table 18 is lowered, the distance between the front and back metal plates 1 and 2 and the position of the side jigs 20 are determined, and the injection nozzle 21 is inserted into the injection port 22 to become the heat insulating material 3. A heat insulating roofing material A is manufactured by injecting and curing a urethane resin. In the figure, 23 is an injection device, and 24 is an air cylinder.

FIG. 8 shows another embodiment of the heat-insulating roofing material A, in which the number of peaks 4 is reduced as compared with the above-described embodiment. In this embodiment, as shown in FIG. 9, only the front metal plate 1 is extended to form an eaves connecting portion 13 at the eaves-side end of the heat-insulating roofing material A. I have. The step portion 7 is also formed in the eaves connection portion 13. The back side of the heat insulating material 3 at the end of the eaves forms an alligator connection recess 14. The back side of the heat insulating material 3 of the ridge forms an alligator connecting projection 15. This connection recess 1
5 is formed of a heat insulating material 3. Note that the length of the eaves connecting portion 13 can be variously changed depending on the length of cutting off the heat insulating material 3.

Thus, as shown in FIG. 10, the eaves connecting portion 13 of the insulated roofing material A is connected to the connecting portion 16 of the insulated roofing material A, which is laid on the eaves. The portions 7, 7 are engaged with each other to be connected, and the connection protrusions 15 of the heat insulating material 3 are connected.
The connection between the heat insulating roofing materials A and A in the building eaves direction is performed by connecting the connecting recesses 14 and the connecting recesses 14 unevenly. Such a connection structure in the ridge direction may be adopted in the embodiment in FIG.

According to the first aspect of the present invention, the ridges are formed at an interval in the width direction so as to have a full length in the ridge direction, and the ridges, the flat portions between the ridges, the connecting portions and the connected portions are formed. Because the steps are formed at intervals in the direction, the top of the roof in the direction of the eaves and the steps that are perpendicular to the top are grid-shaped, and the sandwich panels are insulated. In this case, there is an advantage that the appearance can be enhanced. In addition, there is an advantage that the strength of the heat-insulating roof material can be increased by the rib effect of the mountain portion and the step portion.

In the second aspect, since the height of the step portion in the flat portion and the height of the step portion in the mountain portion are made equal, the appearance when the insulated roofing material laid on the roof is looked up from the eaves can be further enhanced. There is an advantage that you can. In claim 3, the connecting portion and the connected portion are formed in a semi-mountain shape, the connecting portion is formed by extending only the front metal plate, and the connected portion has a heat insulating material on the back surface of the front metal plate. A hook-shaped connecting piece is formed by bending a hook-shaped connecting piece downward at the tip of the connecting part, and a concave part is formed in the connected part to form a drainage space when the connecting piece is locked to the connected part. Therefore, the connecting piece formed by extending the metal plate can be divided in the ridge eaves direction by the step, and the divided connecting piece can be strengthened by the rib effect at the step, and as a result, the heat insulating roof material There is an advantage that the connection strength can be increased. Moreover,
When the connection piece is connected to the connected part, a drainage space can be formed between the connection piece and the connected part, and the advantage that rainwater can be effectively prevented from entering from the connection part can be obtained. is there.

In the fourth aspect, the recess for accommodating the upper portion of the mountain portion is formed in the entire length in the direction of the eaves, so that the lower portion of the heat insulating roof material can be heat-insulated. By inserting it into the recess of the roofing material, there is an advantage that the upper and lower heat insulating roofing materials can be stably stacked, which is advantageous in transportation and the like.
