The resin foam material of the same material as the material 3 is injected and foamed to fill the foamed resin 10 with the heat insulation material 3 of the heat insulating roof panel 4, and the above problem is solved by this configuration. . [Function] A foamed resin layer 10 filled with a resin foam material is injected and foamed into a closed space 9 formed by the upper end surface of the outer wall 6 and the lower surface of the heat insulation roof panel 4, and the heat insulation material 3 of the heat insulation roof panel 4 is provided thereunder. Since the metal plate 2 is adhered to the metal plate 2 through the notch 30, the moisture-proof property and the heat insulating property are ensured. The present invention will be described below based on embodiments shown in the accompanying drawings. As the metal plates 1 and 2, a colored zinc iron plate, a colored aluminum plate, a colored aluminum zinc alloy plated steel plate, a stainless steel plate, a titanium steel plate or the like is adopted. A foamable synthetic resin material such as hard urethane foam, isocyanurate foam, or phenol foam mixed with a polyol, an isocyanate, a catalyst, a foaming agent or the like is injected between the upper and lower metal plates 1 and 2, and foamed to be a heat insulating material. 3 is filled to form an insulating roof panel 4. As shown in FIG. 4, the upper metal plate 1 is bent into a corrugated cross section, and a plurality of ridges 11 are formed in the longitudinal direction on the surface of the heat insulating roof panel 4, and the metal plate 1 is formed on one side. The side edge of the is extended to form a covering piece 12, and a locking step portion 13 is formed on the inner side surface of the mountain portion 11 on the other side portion. Further, the lower metal plate 2 is bent to form an insertion concave portion 14 and an insertion convex portion 15 at the lower portions of both ends of the heat insulating panel 4, respectively. A packing 16 is attached to the back surface of the covering piece 12 of the heat insulating roof panel 4 and the end surface of the other side portion. At one end of the heat insulating panel 4 in the longitudinal direction, the lower metal plate 2 is cut together with the heat insulating material 3 for a predetermined length to form a connecting piece 17 made of the end of the upper metal plate 2. Thus, the heat insulating roof panel 4 is laid on the purlin 5 made of shaped steel with the longitudinal direction parallel to the eaves direction. In the eaves direction, as shown in Fig. 2, the connecting piece 17 of the upper insulating roof panel 4 is shown.
Is covered on the end of the lower insulating roof panel 4, and a fixing tool 18 such as a tex is inserted into the purlin 5 from the connecting piece 17 and fixed. In this embodiment, a moisture impermeable tape 23, which is a butyl tape, is laid on the purlin 5 of the lower metal plate 2, and the fastener 18
Prevents moisture from permeating around. In the direction of the purlin 5, as shown in FIG. 3, the heat insulating roof panels 4 are attached to each other at their side portions, and the mountain portion 11 of one heat insulating roof panel 4 is covered with the covering piece 12 of the other heat insulating panel 4 to cover the piece. 12 locking bent pieces
19 is locked to the locking step portion 13 of the mountain portion 11, the insertion convex portion 15 is inserted into the insertion concave portion 14, and the fixing tool 24 is moved from the covering piece 12 to the fixing metal fitting 2.
First, the sealing tape 22 is passed through the mountain portion 11 to be inserted and fixed to the purlin 5 to which the moisture impermeable tape 28 which is a butyl tape is attached. A plastic cap 32 is fitted on the head 24a of the fixing tool 24, and a decorative cover 25 is attached to the joint between the heat insulating roof panels 4 by being locked at both side edges of the fixing metal fitting 21. Are formed. In this embodiment, a butyl tape is attached to the recess 27 of the insertion projection 15 to form a moisture-proof layer 29 under the side portions of the heat insulating roof panels 4. In the roof eaves constructed in this manner, the gap between the indoor outer upper end of the outer wall 6 which is an ALC plate and the lower surface of the heat insulating roof panel 4 is attached via the butyl tape 23, respectively, and the eaves drainage plate 7 and the closing plate. A closed space 9 is formed by the upper end surface of the outer wall 6 and the lower surface of the heat insulating roof panel 4 by being closed by 8. The lower metal plate 2 portion facing the closed space 9 of the heat insulating roof panel 4 is cut out over the entire length in the direction of the purlin 5 with a width of about 50 mm, and the heat insulating material 3 is exposed at this cutout 30. A foaming synthetic resin material is injected into the space 9 and is foamed to fill the foaming resin layer 10. In this case, foaming causes the foamed resin material to penetrate into the inside of the heat insulating roof panel 4 through the notch 30 and closely adhere to the heat insulating material 3. The foamable synthetic resin material to be injected is the heat insulating material 3 of the heat insulating roof panel 4.
It is preferable to use the same material as that because the adhesiveness is improved. or,
The arabesque parting 31 is driven into the eaves tip of the heat insulating roof panel 4 to ensure moisture resistance.

【The invention's effect】

The present invention is a roof eave structure formed by laying a heat-insulating roof panel formed by filling a heat insulating material between upper and lower metal plates on a main roof, wherein The space between the lower surface is closed by the eaves draining plate and the closing plate to form a closed space between the upper end surface of the outer wall and the lower surface of the heat insulating roof panel, and the metal plate below is the part facing the closed space of the heat insulating roof panel. Since a long notch is formed in the direction of the purlin to expose the heat insulating material, and the foamed resin layer filled by injecting and foaming the resin foam material into the closed space is closely adhered to the heat insulating material of the heat insulating roof panel, The insulating material of the insulating roof panel is exposed at the notch that is formed in the metal plate under the panel in the long direction toward the purlin, and the sealed space is filled with the resin foam material of the same material as the insulating material of the insulating roof panel. Pa Integrated with the heat insulating material of the roof, the sealed space and the insulating roof panel can be connected satisfactorily without creating a gap, the airtightness between the insulating roof panel and the outer wall is improved, and moisture resistance and heat insulation are secured. Therefore, it can be suitably used in a hot and humid factory.
