  However, in the roof material integrated solar cell module of Patent Document 1, the solar cell module placed on the folded roof material is directly exposed to sunlight and directly exposed to wind and rain, so that the solar cell module deteriorates in a relatively short period of time. There is a problem of doing.

  As a means for solving such a problem, for example, it is conceivable to vacuum laminate the surface of the solar cell module with a transparent weather resistant resin film. In that case, a short solar cell module capable of vacuum lamination is manufactured, Since a number of laminated short solar cell modules that are laminated are connected in the length direction of the folded roof material, each connection portion must be sandwiched and fixed by a solar cell module fixing member. There is a new problem that the installation work of the module is troublesome and the workability is not good.

  In addition, the roof material integrated solar cell module of Patent Document 1 has a problem in that it is dangerous because the solar cell module is attached on the folded plate roof material attached to the roof.

  On the other hand, the multi-layered daylighting roof member of Patent Document 2 forms a heat insulating space between two upper and lower light-transmitting folded plates to prevent the fall of condensed water. It is not intended to be compounded.

The present invention has been made under the above circumstances, and the problem to be solved is that it is possible to exhibit various functions over a long period of time by suppressing the deterioration of the solar cell sheet and other functional sheets, and it is easy to manufacture and install. The object of the present invention is to provide a roof structure using a folded-sheet roof material containing a functional sheet with good properties.

In order to solve the above-mentioned problems, the roof structure according to the present invention includes an upper folded plate having a bottom plate portion, left and right inclined side plate portions that rise obliquely upward from both side ends of the bottom plate portion, and upper ends of these inclined side plate portions. The lower folded plate has a bottom plate portion that overlaps with the bottom plate portion of the upper folded plate, and rises obliquely upward outward from both side ends of the bottom plate portion, and the upper folded plate described above. The left and right inclined side plate portions that overlap the inclined side plate portions, and the ear receiving portions that are formed at the upper ends of these inclined side plate portions and receive the above-mentioned ear portions of the upper folded plate , and the bottom plate portion of the upper folded plate , A functional sheet is sandwiched between the bottom plate portion of the lower folded plate, the peripheral portions of the upper folded plate and the lower folded plate are sealed, and the upper folded plate and the lower folded plate are translucent synthetic resin. in the formed feature sheet containing folding plate roofing made of metal folded plate roofing, fixed to the purlin material roof The roof structure is attached to a tight frame, and a metal long through-hole for a folded sheet roof material with a functional sheet and a metal folded plate in the central portion of the mountain portion of the tight frame A metal-made short suspension for roofing materials, and the long threading suspension and a presser fitting for holding the short suspension are fixed, and the engagement edge of the long threading suspension is a folded sheet with a functional sheet.

The curved portion is hooked to the lower edge of the engagement edge of the long threading suspension and the engagement edge of the short suspension, and the short grip is mounted on the long metal cap. The metal plate placed between the hanging parts at the left and right ends of this gripping bracket and the left and right concave portions of the cap and the lower left and right side edges of the gripping bracket are tightened, and the gripping bracket is attached. it is characterized in that there.

In roof construction of the present invention, it is not preferable that upflow prevention material on the upper side of the functional sheet containing folding plate roofing is secured is located.

  A typical example of the functional sheet is a solar cell sheet, but a light control sheet, a phosphorescent sheet, a light emitting sheet, and the like are also preferably used. When sandwiching the solar cell module sheet between the upper folded plate and the lower folded plate, it is sufficient that at least the upper folded plate is formed of a light-transmitting material, but any of the light control sheet, the phosphorescent sheet, and the light emitting sheet When sandwiching between the above, it is possible to form both the upper folded plate and the lower folded plate with a light-transmitting synthetic resin as described above so that the function of each sheet can be seen from the inside through the lower folded plate. preferable.

Like the roof structure of the present invention, when the functional sheet is sandwiched between the bottom plate portion of the upper folded plate and the bottom plate portion of the lower folded plate , and the peripheral portions of these folded plates are sealed, the function There is an advantage that the sheet can be stably clamped so as not to be misaligned, and the functional sheet is covered and protected by these folded plates, so that it is directly exposed to wind and rain, or is damaged by flying objects. And the deterioration of the functional sheet due to sunlight is significantly suppressed. Other Me, can exert various functions by functional sheets over a long period. And since both folded plates are formed with translucent synthetic resin, it can light through the inclined side plate part of both folded plates where the functional sheet is not sandwiched, and the functional sheet is translucent. If it is, it can light through an inclination side board part and a baseplate part. Moreover, this folded sheet roof material with a functional sheet inserts a functional sheet between an upper folded board and a lower folded board in a factory, and seals the peripheral part of both folded boards with the below-mentioned sealing tape or adhesive agent. It can be manufactured easily and efficiently even for long ones, and it is easy to handle like conventional folded plate roofing materials, and the troublesome and dangerous work of attaching functional sheets to the folded plate roofing materials at the roofing site Since it is unnecessary, roofing workability and safety are good. And the roof structure in which the blowing-up prevention material is arranged and fixed on the upper side of the folded sheet roof material with the functional sheet, the folded sheet roof material with the functional sheet is blown up and lifted, peeled off and scattered at the time of strong wind. There is an advantage that can be prevented by the blow-up prevention material.

Further, the folding plates both made of translucent synthetic resin, is intended to function dimming sheet or phosphorescent sheet or a light-emitting sheet as the sheet is sandwiched, are or dimming function exerted by light control sheet, accumulating light sheet The fluorescent light emitted from the light source at night and the light emitted from the light emitting sheet can be viewed from the inside and the outside through both folded plates made of light-transmitting synthetic resin.

  Hereinafter, specific embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a cross-sectional view of a folded sheet roof material with a functional sheet used in a roof structure according to an embodiment of the present invention, and FIG. 2 is an exploded partial perspective view of the folded sheet roof material with the functional sheet.

  This folded sheet roof material R with a functional sheet is composed of an upper folded sheet 1, a lower folded sheet 2, and a functional sheet 3. The upper folded plate 1 and the lower folded plate 2 are preferably formed of a translucent synthetic resin in order to obtain a folded plate roof material R for daylighting. But when using the functional sheet which does not need to be visually recognized from the inside like a solar cell sheet as the functional sheet 3, at least the upper folding plate 1 should just be formed with the translucent synthetic resin. However, even in that case, it is preferable that both the folded plates 1 and 2 are formed of a light-transmitting synthetic resin so that light can be collected from a portion where the solar cell sheet is not sandwiched.

  As the material resin for the upper folded plate 1 and the lower folded plate 2, any translucent (transparent or translucent) thermoplastic resin that can be easily extruded can be used, but among them, the total light transmittance is high and the haze is high. Polycarbonate and polyester resin having low transparency and excellent transparency are preferably used. These material resins may be added with an ultraviolet absorber, a light stabilizer or other additives to improve weather resistance, or a light diffusing agent may be added to diffuse transmitted light. In particular, it is preferable to improve the weather resistance by adding an ultraviolet absorber or a light stabilizer to the material resin of the upper folded plate 1. When the lower folded plate 2 is made opaque, the lower folded plate 2 may be formed of a thermoplastic resin or metal plate made opaque by adding a pigment.

  As shown in FIGS. 1 and 2, the upper folded plate 1 of the functional sheet-containing folded plate roofing agent R includes a horizontal bottom plate portion 1a and left and right inclined side plates that rise obliquely upward and outward from both side ends of the bottom plate portion 1a. Parts 1b, 1b and left and right ears 1c, 1c formed at the upper ends of these inclined side plate parts 1b, 1b, and the edges 1d, 1d of the ears 1c, 1c are inclined inward It protrudes downward and engages with an engaging edge 8a of a threader 8 that will be described later.

  The lower folded plate 2 includes a horizontal bottom plate portion 2a that overlaps with the bottom plate portion 1a of the upper folded plate 1 with a slight gap (a gap substantially equal to the thickness of the functional sheet), and both side ends of the bottom plate portion 2a. The left and right inclined side plate portions 2b, 2b are formed on the upper ends of the inclined side plate portions 2b, 2b. And the ear receiving portions 2c and 2c for receiving the above-mentioned ear portions 1c and 1c of the upper folded plate 1, and as shown in FIG. 2, there is an electrode lead-out in the vicinity of the end in the length direction of the bottom plate portion 2a. A hole 2d is formed.

  These folded plates 1 and 2 can be efficiently mass-produced by the following method, for example. First, the above-mentioned material resin is continuously extruded to produce a flat plate in advance and store it. When the folded plates 1 and 2 become necessary, the flat plate is cut into a predetermined size and bent into the folded plate shape shown in FIGS. 1 and 2 while heating or not heating the bent portion. Processed and manufactured. If a two-layer extrusion molding machine is used when manufacturing the above flat plate and the material resin and the material resin containing a large amount of ultraviolet absorbers are overlapped and extruded simultaneously, the ultraviolet absorber or the like is formed on the upper surface. Folded plates 1 and 2 having a weather resistant layer containing a large amount of can be easily produced.

  Between the bottom plate portion 1a of the upper folded plate 1 and the bottom plate portion 2a of the lower folded plate 2, a rectangular functional sheet 3 having a slightly smaller vertical and horizontal dimension than the bottom plate portion 2a of the lower folded plate 2 is sandwiched. And the peripheral part of the upper folding plate 1 and the lower folding plate 2 is sealed. That is, as shown in FIG. 1, the ear portions 1c, 1c of the upper folded plate 1 and the ear receiving portions 2c, 2c of the lower folded plate 2 are sealed in a watertight manner with the seal tapes 4, 4, and Both end edges in the length direction of the plate 1 and the lower folded plate 2 are sealed in a watertight manner with a similar sealing tape. This watertight sealing process may be performed with an adhesive instead of the seal tape.

  As described above, when the functional sheet 3 is sandwiched between the bottom plate portion 1a of the upper folded plate 1 and the bottom plate portion 2a of the lower folded plate 2, the functional sheet 3 is stably prevented from being displaced. Can be pinched. And if it can light through the inclined side plate portions 1b and 2b of both the folded plates 1 and 2 where the functional sheet 3 is not sandwiched and the functional sheet is translucent, the inclined side plate portions 1b and 2b and Daylight can be obtained through the bottom plate portions 1a and 2a. In addition, when the peripheral edges of the upper folded plate 1 and the lower folded plate 2 are sealed in a watertight manner, the intrusion of rainwater is prevented, and the functional sheet 3 is altered or deteriorated by rainwater, or electrical troubles are caused. There is no need to worry about it. If necessary, the functional sheet 3 may be partially affixed to the bottom plate portion 2a of the lower folded plate 2 with a double-sided adhesive tape or the like, and the functional sheet 3 may be completely fixed.

  As the functional sheet 3, a solar cell sheet, a light control sheet, a phosphorescent sheet, a light emitting sheet and the like having a thickness of 2 mm or less are preferably used, but can be sandwiched between the upper folded plate 1 and the lower folded plate 2. As long as the functional sheet has a thin thickness, those other than those described above can be used.

As the solar cell sheet, a silicon-based solar cell sheet in which a silicon thin film is formed on the surface of the base film is preferably used. Of course, a non-silicon-based solar cell sheet is also used. Specific examples of the silicon-based solar cell sheet include single crystal silicon type, polycrystalline silicon type, microcrystalline silicon type, and amorphous silicon type. On the other hand, specific examples of the non-silicon solar cell sheet include gallium arsenide type, chalcopyrite type, Cu ₂ ZnSnS ₄ type, CdTe—CdS type, InP type, SiGe type, Ge type, ZnO / CuAlO ₂ type, And organic type (dye sensitized type, organic thin film type).

  In addition, as the light control sheet, those in which a photochromic layer that changes color by light on the surface of the base film, a thermochromic layer that changes color by heat, or an electrochromic layer that changes color by application of voltage are preferable. used. Specific examples of photochromic light control sheets include retinal, tetrapyrrole, diarylethene, azobenzene, spiropyran, spirobenzopyran, spirooxazine, fulgide, cyclophane, chalcone, silver supported oxidation The thing which has photochromic layers, such as titanium, is mentioned. Specific examples of the thermochromic light control sheet include those having a thermochromic layer such as a spiropyran, vanadium oxide, halogeno complex, or ethylenediamine derivative. Specific examples of the electrochromic light control sheet Examples include those having electrochromic layers such as tungsten oxide, viologen, and rare earth diphthalocyanine.

  In addition, as the phosphorescent sheet, those in which a phosphorescent layer of zinc oxide-copper, strontium aluminate-europium, strontium aluminate-dysprosium, or the like is formed on the surface of the base film are preferably used.

  In addition, as the luminescent sheet, an electroluminescence layer such as polyphenylene vinylene, arylene, fluorene, diphenylquinoxaline-iridium, zinc-sulfur, etc. that emits light by light irradiation or voltage application is formed on the surface of the base film. Those are preferably used.

  Among the functional sheets, a solar cell sheet having an electrode, an electrochromic light control sheet, and a light emitting sheet are taken out from the electrode extraction holes 2 d of the lower folded plate 2.

  The dimensions and shape of the functional sheet folded plate roof material R are substantially the same as those of the metal folded plate roof material 7 described later. For example, the width dimension is about 450 mm and the width dimension of the bottom plate portion is 210 mm. The height is about 200 mm, and the length is about 2 to 4 m. However, the thickness dimension is different from that of the metal folded plate roofing material 7, the total thickness dimension is about 3 to 5 mm, and the thickness dimension of the upper folded plate 1 and the lower folded plate 2 is about 1 to 2 mm. .

  This folded sheet roof material R with a functional sheet can be efficiently manufactured in the following manner. That is, the above-described material resin or material resin containing an additive is continuously extruded and cut into a predetermined length to produce the upper folded plate 1 and the lower folded plate 2. Then, a rectangular functional sheet 3 prepared in advance is placed on the bottom plate portion 2a of the lower folded plate 2, and a seal tape 4 is pasted on both longitudinal edges of the lower folded plate 2 and the ear receiving portions 2c, 2c. Wear or apply adhesive, overlay the upper folded plate 1 on the lower folded plate 2, and seal the peripheral edge of both folded plates 1 and 2 with sealing tape 4 or adhesive. Then, the folded sheet roof material R with a functional sheet can be manufactured easily and efficiently.

  Since the functional sheet 3 is covered and protected by the upper folded plate 1 and the lower folded plate 2 in the folded sheet roof material R containing the functional sheet as described above, the functional sheet 3 is directly exposed to wind and rain, and deteriorated. No damage is caused by flying objects, and the deterioration of the functional sheet 3 due to sunlight is considerably suppressed. Therefore, when the daylighting portion of the roof is spread with the folded sheet roof material R including the functional sheet, various functions can be exhibited by the functional sheet 3 over a long period of time together with the daylighting function. That is, when the functional sheet 3 is the solar cell sheet, the energy of sunlight transmitted through the upper folded plate 1 can be converted into electric energy to exhibit a power generation function. In the case of the light sheet, the discoloration caused by the presence or absence of sunlight, the discoloration caused by the temperature change, and the discoloration caused by voltage application can be visually recognized from indoor and outdoor, and the functional sheet 3 is the phosphorescent sheet. In this case, the fluorescence emitted at night can be visually recognized from indoors and outdoors, and when the functional sheet 3 is the light emitting sheet, the light emitted by voltage application can be visually recognized from indoors and outdoors. Further, the folded sheet roof material R with the functional sheet can be easily and efficiently manufactured in the factory as described above, and is easy to handle as in the conventional folded sheet roof material. Roofing workability is also good.
