[0008]

Embodiments of the present invention will be described below with reference to the drawings. The roof panel 1 used in this embodiment is shown in FIG.
As shown in (a), a fitting convex portion 6 and a fitting concave portion 7 are provided at both ends of a three-layer panel main body 5 in which the front and back surfaces of the heat insulating material 2 are covered with upper and lower two metal skins 3, 4. Each is formed. The surface of the heat insulating material 2 is formed flat, while
The metal covering 3 in Table layer, relatively low and the height of the cross section chevron shaped floating portion 20 is intermittently projecting curved along the width direction C of the roof panel 1, thereby, the surface of the heat insulator 2 and between the floating portion 20 of the metal covering 3 of <br/> table layer, passages 21 extending along the vertical direction (a direction perpendicular to the paper surface in FIG. 1) the length direction of the panel body 5 is formed.

As the heat insulating material 2, an intermediate portion is made of an inorganic fiber material such as rock wool whose shape has been adjusted to a certain thickness in advance, and both ends are made of an inorganic hard material such as calcium silicate which is shaped by extrusion or the like. Those made of materials can be used. In addition, as shown in FIG. 2A, the heat insulating material 2 may be made of a resin foam material such as urethane foam, isocyanurate foam, and phenol foam, as shown in FIG. In the case of this resin foam material, it becomes possible to embed the bent pieces 40 formed at the ends of the metal sheaths 3 and 4 from the end of the heat insulating material 2, thereby bending the metal sheaths 3 and 4. The gap G between the pieces 40, 40
The heat conduction between the metal shells 3 and 4 can be prevented by
Further, the ends of the metal shells 3 and 4 are locked to the ends of the heat insulating material 2 by the bent pieces 40, respectively, so that the metal shells 3 and 4 can be prevented from peeling from the heat insulating material 2.

FIG. 1C shows a structure in which a shielding material 25 is attached to the surface 2a of the passage 21 on the rock wool (heat insulating material) side.
FIG. 2B shows a structure in which a shielding member 25 is attached to the surface 2a of the passage 21 on the side of the resin foam (heat insulating material). In this case, when hot water or cold water is supplied into the passage 21, the infiltration of water into the heat insulating material 2 can be prevented by the shielding material 25, so that there is no concern that the heat insulating material 2 contains moisture. Can be maintained for a long period of time. The shielding member 25 is made of, for example, metal or plastic, and the shielding member 25
It is intended to prevent the resin foam material from flowing into the inside and to prevent water from entering the resin foam material.

Next, an example of a method for manufacturing the roof panel 1 will be described. First, the upper and lower two metal shells 3 and 4 supplied from the supply device are sent to a molding machine to form both ends of the metal shells 3 and 4 respectively, and a plurality of metal shells are formed only on the lower (surface layer) metal shell 3. After the raised portion 20 is intermittently bent, the heat insulating material 2 is filled between the metal sheaths 3 and 4. Here, the heat insulating material 2
Is an inorganic material, before lowering the upper metal shell 4, an adhesive is applied to each of the metal shells 3 and 4 with an adhesive coating device, and the preformed calcium silicate is placed on the lower side (surface layer).
Each side is inserted into the inside of both ends in the width direction of the metal shell 3 and then preformed rock wool is inserted between the calcium silicates. Further, it is preferable to arrange a shielding member 25 on the upper surface side of the raised portion 20 of the lower metal sheath 3. Thereafter, the upper metal outer skin 4 is lowered to cover the front and back surfaces of rock wool or the like with the metal outer skins 3 and 4, so that the upper metal outer skin 4 and the inorganic material (heat insulating material 2) shown in FIG. Can be manufactured with a plurality of passages 21 formed therein. In this case, the shielding member 25 can be omitted, but after the roof panel 1 is installed, the passage 2
When hot or cold water is supplied into the chamber 1, it is preferable to use the shielding member 25 from the viewpoint of preventing water from entering the inorganic material.

On the other hand, when the heat insulating material 2 is a resin foam material,
Before lowering the upper metal shell 4,
The shielding member 25 is arranged on the upper surface side of the raised portion 20 of the lower ( outer surface) metal outer skin 3 where is formed. This makes it possible to prevent the resin foam material from flowing in by the shielding material 25 when the resin foam material is injected between the metal sheaths 3 and 4. In this manner, the upper metal sheath 4 shown in FIG.
The roof panel 1 in which the plurality of passages 21 are formed between the raised portion 20 and the resin foam material (heat insulating material 2) can be manufactured.

Next, when installing the roof panel 1 manufactured as described above, as shown in FIG. 3, a plurality of roof panels 1 are fixed on a roof base material so that the length direction thereof is along the eaves ridge direction B. At the same time, both ends of the adjacent roof panel 1 in the width direction C are connected to each other. Then, the entrance 21a of the passage 21 of each roof panel 1 is communicated with the space 22 above the ceiling through the ventilation opening 60 provided in the ridge portion 61 of the building, and the passage 2
Hollow duct 2 with outlet 21b of 1 provided in eaves section 62 of the building
3 is connected to the exhaust port 63. Thereby, at the time of snowfall, by operating a fan (not shown) provided in the ventilation port 60 of the ridge part 60, the warm air E warming the first and second floors of the building is moved from the ceiling space 22 to the ridge part. 60 ventilation openings 6
4 can be exhausted into the passages 21 of each roof panel 1 shown in FIG. 4 respectively, and this warm air can be exhausted outside from the hollow duct 23 of the eaves section 62 shown in FIG.

Thus, during snowfall, the entire surface of the roof panel 1 can be easily warmed by supplying the hot air E for air conditioning in the building to the passage 21 in the roof panel 1, and moreover, Since the passage 21 is formed along the back surface of the single metal skin 3 constituting the roof upper surface 3a, the heat in the passage 21 is transmitted to the roof upper surface 3a without loss. Without using, the snow melting on the roof upper surface 3a can be effectively performed with a small number of parts. In addition, since the passage 21 is covered with the metal shells 3 and 4, the appearance of the roof upper surface 3a can be kept good without the passage 21 deteriorating the appearance of the roof. Further, since the passage 21 can be constructed at the same time as the construction of the roof panel 1, the construction can be saved, and the conventional electric wiring and snowfall sensor are not required, so that maintenance is not required.

Further, the shielding member 25 is connected to the surface 2a on the rock wool (heat insulating material) side of the passage 21 shown in FIG.
Surface 2 on the side of resin foam material (heat insulating material) of passage 21 shown in (b)
Since the heat insulating material 2 can be prevented from entering the heat insulating material 2 when the hot water or the cold water is supplied into the passage 21 by the shielding material 25 when the hot water or the cold water is supplied into the passage 21, there is no fear that the heat insulating material 2 contains moisture. The heat insulating effect of the heat insulating material 2 can be maintained for a long time. In particular, when the heat insulating material 2 is a resin foam material, the shielding material 25 not only has an effect of preventing water from entering the resin foam material, but also prevents the resin foam material from flowing into the passage 21 during molding of the resin foam material. Its role is significant in exhibiting the effect of prevention.

On the other hand, in the summer, the roof panel 1 can be cooled effectively by exhausting the cool air for air conditioning in the building to the passage 21 in the roof panel 1, thereby preventing the temperature inside the building from rising. As a result, there is an advantage that one roof panel 1 can be used according to the season. As another embodiment of the present invention, as shown in FIG. 5, a gutter portion 11 is provided at a joint of a roof panel 1 in which a heat insulating material 2 is made of an inorganic material, and the gutter portion 11 is also used as a heating passage or a cooling passage. You may make it. That is, the cover 10 covering the upper surface of the fitting protrusion 6 formed on the end 2b of the adjacent roof panel 1 is provided above the fitting recess 7 formed on the end 2b of the adjacent roof panel 1. Together with
A gutter section 11 having a U-shaped cross section is formed at a lower portion of the fitting recess 7, and the inside of the gutter section 11 is a gap 1 between the fitting projection 6 and the fitting recess 7.
2, and a packing 16a is interposed in the gap 12. If rainwater is exposed from the packing 16a, the rainwater is received by the gutter 11 and drained to the outside, and This ensures that rainwater can be prevented from entering the interior. A mounting portion 13 on which the tip of the fitting convex portion 6 is mounted is formed outside the gutter portion 11, and the mounting portion 13 is lower than the mounting portion 13 outside the mounting portion 13. A nailing portion 14 is formed, and the nailing portion 14 is fixed to a roof base material 90 by a nail 15 penetrating vertically. In FIG. 5, reference numeral 16b denotes a gap 12b below the gutter portion 11.
The packing 16c is inserted into the joint 12c on the front surface side of the fitting portion between the fitting convex portion 6 and the fitting concave portion 7, and 30 is a fitting convex portion whose tip has a thickness D5. 6 is a hooking recess formed on the lower surface of FIG.

Here, when a plurality of roof panels 1 are constructed, one end in the length direction of the gutter section 11 is connected to a ceiling space 22 through a ventilation port 60 provided in a ridge section 61 of the building shown in FIG. And the other end of the gutter 11 is communicated with the exhaust port 63 of the hollow duct 23 provided in the eaves 62,
The gutter section 11 can be used also as a heating passage or a cooling passage. That is, at the time of snowfall, the gutter section 11 is heated by exhausting the hot air E or hot water for air conditioning from the under-the-ceiling space 22 into the gutter section 11 through the ventilation opening 60 of the ridge section 60, thereby heating the gutter section 11. The entire joint portion of the panel 1 is easily heated, and the snow on the roof upper surface 3a can be effectively melted without using a conventional snow melting heater. On the other hand, in summer, by supplying cold air or cold water for air conditioning to the gutter portion 11, the gutter portion 11 is cooled and the temperature inside the building can be effectively prevented from rising. Similarly, one roof panel 1 can be used according to the season. Moreover, the gutter section 11 is connected to the cover section 10.
Since the gutter portion 11 is covered from above, there is no concern that the gutter portion 11 lowers the appearance of the roof, the appearance of the roof upper surface 3a can be kept good, and the gutter portion 11 is formed integrally with the roof panel 1. Since the gutter portion 11 can be constructed simultaneously with the construction of the roof panel 1, the construction of the gutter portion 11 can be reduced, and the conventional electric wiring and snowfall sensor are unnecessary, so that no maintenance is required. There is an advantage that it becomes.

Further, in this embodiment, since the fitting projection 6 is supported by the mounting portion 13 in the fitting recess 7, wind pressure, snow load, and the like are applied from above the joining portion of the roof panel 1. In this case, the supporting force of the fitting convex portion 6 is increased, and the strength of the joint portion can be improved. In addition, the joint portion on the surface side of the fitting portion between the fitting convex portion 6 and the fitting concave portion 7 can be improved. Since the hollow joint packing 16c is interposed in the joint 12c, the joint packing 16c can surely prevent infiltration of rainwater from the joint 12a, and can further improve the watertightness of the joint. . Further, the hooking recess 30 is formed on the lower surface of the fitting convex portion 6, so that the mounting portion 13 of the roof panel 1 is formed.
By merely hooking the hooking recess 30 of the fitting protrusion 6 of the roof panel 1 adjacent to the roof panel 1, the fitting protrusion 6 can be temporarily fixed in the fitting recess 7, and the fitting recess 7 of the roof panel 1 When fixing to the base material 90, it is not necessary to hold down the roof panel 1 by hand, and as a result, the work of fixing the roof panels 1 and 1 can be easily performed. In addition, the packing 16 is held in a state where the fitting projection 6 is hooked on the hook recess 30.
a, 16b, and 16c may be compressed. In this case, in addition to the improvement in water tightness by the packings 16a, 16b, and 16c, the fitting convex portion 6 and the hooking concave portion are formed by a reaction force from the packings 16a, 16b, and 16c. Since the engagement force with the place 30 is increased, there is an advantage that the temporary fixing of the roof panel 1 can be more reliably performed, and the work of fixing the roof panel 1 can be performed more easily.

FIG. 6 shows a joint portion of the roof panel 1 when the heat insulating material 2 is a resin foam material, and the bent pieces 40 formed at the ends of the metal shells 3 and 4 are connected to the ends of the heat insulating material 2. The heat conduction between the metal shells 3 and 4 can be prevented by the gap G between the bent pieces 40 and 40 of the metal shells 3 and 4. The ends are respectively locked to the ends of the heat insulating material 2 so as to prevent the metal sheaths 3 and 4 from peeling off from the heat insulating material 2. Other configurations are the same as those of the embodiment of FIG.
