Field of the Invention The present invention relates to a solar heat collecting roof for utilizing a roofing material itself as a heat collecting body to capture solar heat and transmitting the heat to the outside air flowing through the inside to heat a necessary place.

トを屋根下地材の外面に配置して集熱を行っている。In Japanese Patent Publication No. 6-92844 and Japanese Patent Application Laid-Open No. 58-198649, a glass plate substantially serving as a roofing material, a heat collecting plate provided on the inner surface of the glass plate, and a heat collecting plate are disclosed. A heat collecting unit is composed of a heat insulating material that covers the inner surface of, and a case that supports these, and a large number of units are arranged on the outer surface of the roof base material to collect heat.

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

の建築コストを押し上げてしまう。Thus, 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 becomes large, it is necessary to fully consider the roof support structure and its strength, which increases the construction cost of the building as a whole.

層にかびが発生して異臭の原因となることもある。The board-shaped hard heat insulating material can be easily installed with less labor, but a gap is likely to be formed on the adjacent surface of each board, and a heat insulating treatment for closing the gap is indispensable.
In this respect, the mat-shaped heat insulating material has a high degree of sealing action,
Insulation can be performed without trouble even on irregular surface walls with protruding bolts. 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 infiltrated rainwater is impregnated into the heat insulating material. Therefore, the captured solar heat is consumed by the evaporation 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 collecting unit may become abnormally high, which may cause dew condensation at the distribution destination of the collected air, or mold on the heat insulating layer to cause an offensive odor.

To provide a heat collecting roof. Another object of the present invention is to provide a solar heat collecting roof capable of easily performing heat insulation on the inner surface of the air passage with a small amount of labor and maintaining a sufficient airtight state for a long period of time.
Still another object of the present invention is to provide a solar heat collecting roof capable of positively flowing down the discharged rainwater along the heat insulating material and discharging it even if the rainwater enters the air passage for some reason.

Between the roof 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. An air passage 3 reaching the ridge side is secured. The air passage 3 communicates with the outside air through an inlet 9 provided in the eaves wall 8, and communicates with the indoor side through a passage 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. Heat insulation wall 5
As shown in FIG. 4, a heat insulating material 19 is contained inside, and a large number of sandwich panels 17 whose outer surfaces are covered with a waterproof wall 18 are laid and formed. Then, joint portions 20 and 21 are provided on both sides of the sandwich panel 17 in the eaves direction so as to overlap at least in the thickness direction and seal a gap between adjacent panels.

An airtight seal body 22 is provided on at least one of 21 as shown in FIG. The inlet 9 of the air passage 3 is shown in FIG.
As shown in FIG. 5, the perforated plate 12 is covered, and the frame 6 is provided with a group of vent holes 25 as shown in FIG. A group of the frame bodies 6 are arranged in parallel along the eaves ridge direction, and a group of the roofing material 1 for the thatch is fixed to the upper surface of the frame body 6 with the suspenders 13. The waterproof wall 18 of the sandwich panel 17 is formed of a painted steel plate.

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 constantly in contact with the inner surface of the surface wall of the roofing material 1. Therefore, when the roof material 1 is warmed by the solar heat, the heat is transmitted to the air inside through the face wall. The heated air flows toward the ridge and is heated by the upper roof material 1, and the heat collecting plate 2 of the heat collecting unit 2 is further heated.
Heated at 8. In this way, if the roofing material 1 itself is used as a heat collecting body to capture solar heat, the heat collecting efficiency is somewhat inferior to the case where heat is collected only by the heat collecting unit. The cost can be reduced to the same level as a normal roof, and the total weight can be reduced.

吹き込みを防ぐためである。Using a group of sandwich panels 17 containing a heat insulating material 19 and an outer surface covered with a waterproof wall 18,
Since this forms the heat insulating wall 5 for the air passage 3, the construction can be performed easily. Moreover, in the installed state, the adjacent gaps of the sandwich panel 17 can be sealed with the joint portions 20 and 21, and sufficient airtightness can be exhibited. Connecting part 14 of roofing material 1
Since the seal bodies 15 and 22 are also provided on the joint portions 20 and 21 of the sandwich panel 17, the airtight state of the air passage 3 can be reliably maintained. Since the outer surface of the sandwich panel 17 is formed of the waterproof wall 18, even if rainwater enters the air passage 3, the rainwater does not infiltrate into the heat insulating wall 5, and most of it can be made to flow down and be discharged to the outside. . The introduction port 9 is covered with the perforated plate 12 in order to prevent dust, flying insects, and the like from entering the air passage, and further prevent wind and rain from being blown in.

いコストで得ることができる。According to the present invention, most of the roof is roofed by the roofing material 1 made of a metal plate, the roofing material 1 is used as a heat collecting body to heat solar heat, and the heat collecting unit is further provided on the ridge side. The heat collected in 2 was transferred to the air flowing along the roof surface. Therefore, although the heat collection amount and 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 material cost and construction cost of the roof and the roof weight are sufficiently reduced, and The cost can be reduced to the same level as a building with a normal roof, and an energy-saving building that consumes less energy 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 containing the heat insulating material 19, heat insulating work can be easily performed with a small amount of labor. Can maintain essential airtightness for a long time. Furthermore, 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 rainwater that has entered the air passage 3 from soaking into the heat insulating wall 5 and to be impregnated therewith. It has the advantage that it can be positively removed by flowing it down to the eaves along the panel surface, and that the heat collecting function of the solar heat collecting roof can be maintained in a good state for a long time.
