Embodiments of the present invention will be described in detail below with reference to the drawings.

The heat insulating roofing material 3 is a material in which a resin heat insulating material 2 made of hard foamed synthetic resin such as urethane resin is filled between the front and back metal plates 1, 1, and as shown in FIG. and the lower forming conveyor 13, the front side metal plate 1 and the back side metal plate 1
and these two metal plates 1,
14 unfoamed resin material such as urethane resin between
is supplied from the injection nozzle 15, and the unfoamed resin material 14 is foam-molded between both metal plates 1, 1 to continuously produce long roofing material blanks 16, which are then cut to a certain length to form an insulated roof. An intermediate product (not shown) of material 3 is obtained. In such a case, the metal plate 1 on the front side is formed with peaks 18 and troughs 19 long in the feeding direction by the forming roll device 17 during its feeding. A resin heat insulating material 2 is foam-molded between a metal plate 1 on the front side having a flat surface and a flat metal plate 1 on the back side. Then, at the eave side end of the intermediate product obtained by cutting the long original roofing material plate 16 to a certain length, the metal plate 1 on the back side and the resin insulation material 2 above it are cut and separated, and the metal plate on the front side is separated. The plate 1 is made to protrude in the direction of the eaves in the eave ridge direction beyond the exposed end face 4 on the eaves side of the resin cut material 2 and the metal plate 1 on the back side to form a protruding folded part 5.

As shown in FIG. 4, the eaves edge trimming material 9 is formed by bending a thin metal plate, and the cover piece 7 of this eaves edge trimming material 9 has a shape approximately equal to the shape of the resin cut material 2. An abutment piece 6 is extended from the upper edge of the cover piece 7 so as to protrude in the direction of the eaves. At the lower edge of the cover piece 7, a grip piece 20 is extended diagonally upward to the rear.

However, as shown in Fig. 1, the eaves finishing material 9
The abutting piece 6 is brought into contact with the lower surface of the protruding folded part 5, and the cover piece 7 is brought into contact with the exposed end surface 4 on the eaves side of the resin heat insulating material 2, and the folded piece 8 at the tip of the protruding folded part 5 is folded downward. By holding the abutting piece 6 between the folded piece 8 and the protruding folded part 5 in this way, a connection such as a seam connection can be made, and watertightness at this connection point can be achieved. has been secured. Further, a connecting fitting 21 having an L-shaped cross section is attached to the metal plate 1 on the back side with watertight rivets 10, and a gripping piece 20 is loosely engaged with a vertical piece 22 of this connecting fitting 21. This area is made watertight by tightening it with a tightening tool such as pliers.

A connecting portion 23 formed by bending the metal plate 1 on the front side is formed at one end in the width direction of the insulating roofing material 3, and a connected portion 24 to which the connecting portion 23 can be connected is formed at the other end. has been formed. The eave side end of the connected part 24 laid on the lower surface of the connecting part 23 is notched, and by providing the notch 25 in this way, the eave edge at the connecting part of the insulating roofing materials 3, 3 is cut out. This prevents the portion from becoming duplicated, making it easy to connect the eaves trimming material 9 to this portion.

As shown in FIGS. 6 to 8, the peaks 18 at appropriate locations of the heat insulating roofing material 3 constructed in this manner are as shown in FIGS.
A makeup cap 26 is attached, and the vertical interval is 28
Cap the eave side opening and the end face of the peak 18 with the side door 2
It is blocked by 7. The configuration will be explained below.

As shown in FIG.
Attachment holes 29 are formed in each of the protruding folded portions 5 that are substantially flush with both oblique pieces. The lower half of the mirror plate 30 of the cap door 27 has a shape substantially equal to that of the peak 18, and the upper half thereof has a protrusion 31 that protrudes beyond the top of the peak 18 and an overhang 32 that protrudes in the left and right lateral directions.
A mounting piece 33 extends rearward from the periphery of the mirror plate 30 thus formed to form a cap surface door 27.

However, the cap door 27 was fixed with blind rivets 34.
Then, it is attached to the crest 18 and the decorative cap 26 via the attachment piece 33. In such a case, the mirror plate 30
The protruding portion 31 protrudes from the top of the mountain portion 18. The cosmetic cap 26 extends to the ridge, and ridge retainers (not shown) are attached to the cosmetic caps 26, 26 on both sides sandwiching the ridge.

The configuration in which the lower end of the cover piece 7 is watertightly connected to the metal plate 1 on the back side is as shown in FIG.
In addition to using the connection fitting 21,
As shown in the figure, the lower end of the cover piece 7 is overlapped and folded back, the horizontal piece 36 is bent backward from the upper end of this folded piece 35, and the tip of the horizontal piece 36 is Various design changes are possible, such as by folding the upper folding piece 37 upwardly, abutting the upper folding piece 37 against the metal plate 1 on the front side, and connecting it watertightly with a blind rivet 34.

(Effects of the invention) In short, the present invention involves folding back the end of the eaves side of the protruding folded part formed in series on the metal plate on the front side downward, so that this folded piece touches the lower surface of the proximal end of the protruding folded part. Since it is configured to hold the abutting pieces in contact with each other, there is nothing protruding on the metal plate on the front side, which has the advantage that it does not impede the drainage of rainwater or especially snowfall. Moreover, since the tip of the protruding folded parts formed in series on the metal plate on the front side is folded back to hold the abutting piece of the eaves binding material, in other words, the abutting piece can be held by simply folding back the protruding folded parts. Therefore, a connection such as a seam connection can be made without separately preparing a seal structure, and high sealing performance can be obtained. In addition, the insulating roofing material is fixed to the main building with large mounting bolts such as self-drilling screws, but these self-drilling screws are used from the surface side to firmly attach the insulating roofing material of the sanderch structure. The bolts are fixed to the main building by passing through them, and as a result, the heads of the bolts protrude and become exposed on the surface of the insulating roofing material, which obstructs snow removal and makes the exterior look unsightly. There is a problem that rain leaks from the head of the mounting bolt to the main building side due to installation errors, but this invention solves this problem by covering the peaks of the insulating roof material at appropriate locations along the direction of the eaves. By attaching the decorative cap, the heads of the large mounting bolts used to attach the insulated roofing material to the main building are hidden by the cosmetic cap, and the heads of the large mounting bolts do not get in the way when removing snow, and the appearance is improved. This also hides the heads of large mounting bolts and allows for a decorative finish with a decorative cap.Furthermore, it can prevent rain from leaking into the main building through the mounting bolts that penetrate the insulating roof material. The opening on the eave side at the vertical interval between the cap and the peak and the edge of the peak are covered by a cap surface door located in a position that projects forward beyond the edge of the peak, so it corresponds to the front end and peak of the decorative cap. There is an advantage that the cap-face door can enhance the appearance of the eaves by giving the appearance as if a decorative rafter were protruding forward.
