Description of the Related Art Japanese Patent Publication No. Hei 6-92844 and Japanese Patent Application Laid-Open No. 58-198649 disclose a glass plate which substantially also serves as a roofing material, a heat collecting plate provided on the inner surface of the glass plate, and a heat collecting plate. A heat collecting unit is composed of a heat insulating material covering the inner surface of the roof and a case supporting the heat insulating material, and a large number of units are arranged on the outer surface of the roof base material to collect heat.

At this time, the inner surface of the passage is covered with various heat insulating materials in order to prevent heat dissipation from the air passage and improve thermal efficiency. For example, in the former of the conventional example, a mat-like heat insulating material such as rock wool or glass wool is spread in a case to achieve heat insulation.
A hard heat insulating material such as a foamed plastic board, a wooden wool board, or a glass wool board may be used.

の建築コストを押し上げてしまう。As described above, the solar heat collecting roof using the heat collecting unit can efficiently collect the solar heat, but the material cost and the construction cost are higher than those of the ordinary roof. Since the roof weight is increased, the roof support structure and its strength must be sufficiently considered, which increases the construction cost of the building as a whole.

In this regard, the mat-like heat insulating material has a high sealing effect,
Insulation can be performed without any problem even on irregular wall surfaces where bolts protrude. However, when rainwater enters the air passage due to, for example, breakage of the seal during long-term use, a fatal problem occurs. All the soaked rainwater is impregnated into the insulation. Therefore, the captured solar heat is consumed for the evaporating action of the impregnated water, and the thermal efficiency of the heat collecting unit is significantly reduced. The humidity of the air collected from the heat collection unit may become abnormally high, causing dew condensation at the distribution destination of the collected air, or generating mold on the heat insulating layer, which may cause an odor.

る。As shown in FIG. 1, a solar heat collecting roof according to the present invention is provided with a heat collecting unit 2 for capturing solar heat on a ridge side of a roof covered with a roofing material 1. Between the roofing material 1 and the heat collecting unit 2 and the heat insulating wall 5 arranged on the outer surface side of the purlin 4, as shown in FIG. Secure the air passage 3 to the building side. The air passage 3 communicates with the outside air through an inlet 9 provided in the eaves ceiling wall 8 and communicates with the indoor side through a communication port 10 provided in the heat insulating wall 5 near the ridge end. The roof material 1 is formed of a metal plate material having high thermal conductivity, and the inner surface of the surface wall faces the air passage 3. Insulation wall 5
Is formed by laying a large number of sandwich panels 17 in which a heat insulating material 19 is included and an outer surface is covered with a waterproof wall 18 as shown in FIG. Then, on both sides of the sandwich panel 17 in the eaves ridge direction, joint portions 20 and 21 for overlapping at least in the thickness direction to seal a gap between adjacent panels are provided.

At least one of the seals 21 is provided with an airtight seal 22 as shown in FIG. The inlet 9 of the air passage 3 is shown in FIG.
As shown in FIG. 5, the frame 6 is provided with a group of ventilation holes 25 as shown in FIG. One group of the frame bodies 6 is arranged in parallel in the direction of the eaves ridge, and a group of the roofing materials 1 for roofing is fixed to the upper surface thereof through the suspension 13. The waterproof wall 18 of the sandwich panel 17 is formed of a painted steel plate. With this specific configuration, arranging the heat collecting unit 2 on the ridge side of the roof over substantially the entire ridge direction is advantageous in adopting a mode in which solar heat is collected over the entire roof.

まで圧縮でき、その全体重量も小さくできる。The air in the air passage 3 is always in contact with the inner surface of the roof material 1. Therefore, when the roofing material 1 is warmed by the solar heat, the heat is transmitted to the internal air through the face wall. The heated air is heated by the upper roofing material 1 while flowing to the ridge side, and is further heated by the heat collecting plate 2 of the heat collecting unit 2.
Heated at 8. As described above, when the roof material 1 itself is used as a heat collector to capture solar heat, the heat collection efficiency is somewhat inferior to the case where heat collection is performed only by the heat collection unit. The cost can be reduced to the same level as a normal roof, and its overall weight can be reduced.

吹き込みを防ぐためである。Using a group of sandwich panels 17, which enclose a heat insulating material 19 and whose outer surface is wrapped by a waterproof wall 18,
Since the heat insulating wall 5 for the air passage 3 is thus formed, the construction can be performed easily. In addition, in the construction state, the adjacent gap of the sandwich panel 17 is sealed with the joint portions 20 and 21, and sufficient airtightness can be exhibited. Connecting part 14 of roofing material 1
Also, since the joints 20 and 21 of the sandwich panel 17 are also provided with the seals 15 and 22, respectively, the airtight state of the air passage 3 can be reliably maintained. Since the outer surface of the sandwich panel 17 is formed by the waterproof wall 18, even if rainwater enters the air passage 3, the rainwater does not permeate into the heat insulating wall 5, and most of the rainwater can flow down and be discharged to the outside. . The reason why the inlet 9 is covered with the perforated plate 12 is to prevent dust and flying insects from entering the air passage and to prevent wind and rain from being blown.

いコストで得ることができる。According to the present invention, most of the roof is laid up with a roofing material 1 made of a metal plate, and the roofing material 1 is used as a heat collector to heat the solar heat. The heat collected in 2 was transmitted to the air flowing along the roof surface. Therefore, although the amount of heat collected and the heat collection efficiency are reduced as compared with the solar heat collection roof in which the heat collection unit is arranged on the entire roof, the cost of the roof material, the construction cost, and the roof weight are sufficiently reduced, and the total building The cost can be reduced to the same level as a building with a normal roof, and an energy-saving building requiring less energy consumption in the cold season can be obtained at a lower cost.

長期にわたって良好な状態に維持できる利点を有する。Since the heat insulating wall 5 of the air passage 3 is formed by joining and connecting a group of sandwich panels 17 including the heat insulating material 19, the heat insulating work can be easily performed with a small amount of labor, and the heat insulating wall 5 can be formed. Indispensable airtightness can be maintained for a long time. Further, since the outer cover material of the sandwich panel 17 is formed of a steel plate to form the waterproof wall 18, it is possible to prevent the rainwater that has entered the air passage 3 from penetrating into the heat insulating wall 5 and impregnating the same. It has the advantage that it can be positively removed by flowing down to the eaves side along the panel surface, and the heat collecting function of the solar heat collecting roof can be maintained in a good state for a long time.
