Japanese Patent Application No. 61-311485 (Japanese Patent Laid-Open No. 63-165633) Japanese Patent Application No. 62-234666 (Japanese Patent Application Laid-Open No. 64-75858)

  When the outline is demonstrated about FIG. 16, the air flow path 2 which has a roof gradient is formed in the solar heat collection part provided in a roof directly under the metal roof boards 1, such as a color iron plate, The one end of this air flow path 2 is It opens to the eaves etc. (it may be a back of a hut) as the external air intake 3, and the other end is connected to the ridge duct 4 as a heat collection box by a heat insulating material.

  The lower surface of the air flow path 2 was configured as a heat insulating layer 24 made of a panel board such as glass wool, and a part of the roof was covered with glass 23. The glass 23 prevents the wind from inhibiting the metal roof plate 1 from being heated by solar heat when the external wind is strong.

  A handling box 5 provided with an inflow side damper 6, a heat collecting fan 7 and an outflow side damper 8 is installed in a shed 22 which is an attic space, and one of the outflow side of the outflow side damper 8 is outdoors by an exhaust duct 9. And the other one is connected to the upper end of the falling duct 10. The lower end of the falling duct 10 opens into the air circulation space 13 between the thermal storage soil concrete 11 and the floor panel 12 as a heat storage / radiation part, and a floor outlet 14 from the air circulation space 13 to the room is provided. .

  One of the inflow sides of the inflow side damper 6 of the handling box 5 was communicated with the ridge duct 4 and the other one was connected to a circulation duct 19 opened indoors through a ceiling or the like. If the room provided with the suction port 20 through which the circulation duct 19 is open is on the second floor, the room having the floor panel 12 provided with the floor outlet 14 to the room and the room on the first floor provided with a blow-off structure is air. It is desirable to make the flow freely.

  In the handling box 5, a hot water take-off coil 15 is provided between the inflow side damper 6 and the heat collecting fan 7, and the hot water take-off coil 15 is connected to a hot water storage tank 17 by a circulation pipe 16. A hot water supply boiler 18 for reheating is provided on the way, and a hot water supply pipe 21 connected to a bath, a washroom, and a kitchen is connected.

  In this way, the roof plate 1, which is a metal plate heated by sunlight, warms the outside air entering the air flow path 2, and the warmed air rises along the roof gradient. The heated air is collected in the building duct 4 and then enters the handling box 5 by the heat collecting fan 7 and flows down from the handling box 5 through the falling duct 10 between the thermal storage soil concrete 11 and the floor panel 12. Enter the air circulation space 13. In this air circulation space 13, heated air directly warms under the floor surface via the floor panel 12, stores heat in the thermal storage soil concrete 11, and is blown directly into the room as warm air from the floor outlet 14. The three types of heating are performed.

  On the other hand, the hot water coil 15 heats the water fed from the hot water storage tank 17 through the circulation pipe 16 and stores it as hot water in the hot water storage tank 17. The water is reheated and hot water is supplied from the hot water supply pipes to various places.

  As the solar heat collecting part provided on the roof, for example, as shown in FIG. 17, as a floating roof of a tiled bar type, the rafters 25a and 25b having different diameters are doubled up and down with the rafter 25a having a large diameter on the bottom. It is assumed that there is a step, and a roof plate 1 made of a colored iron plate is wound here to secure an air layer 2a on the lower side to form an air flow path 2.

  The airtightness of the air layer 2a is ensured by applying a sealing material 26 such as silicon caulking to the outer surface of the rafters 25a and 25b with a caulking gun or the like and then overlapping the end of the roof plate 1.

  In the floating roof of the tiled-barrel type, the material used for the heat collecting part will be exposed to high-temperature air in summer, and depending on the material used, there may be anxiety in terms of durability and long-term reliability. .

  In particular, wood that is difficult to control the quality of the material may be warped, rotted, or thin, and affect the mounting strength of the roofing material.

  In the case of the floating roof structure tiled roof, the distance between the roof plate 1 and the glass 23 needs to be waterproof, and about 40-50 mm is required. This is because the roof plate is bent upward by about 40-50 mm in order to be waterproof.

  The object of the present invention is to eliminate the inconveniences of the conventional example, and to eliminate the conventional wooden rafters and to make metal parts, so that it is possible to construct a stable and reliable roof over a long period without using a sealing material, When installing glass on it, the distance between the glass and the roof plate can be made as close as possible to increase the heat collection efficiency, and it is a supplementary member for constructing the roof by flattening. Another object is to provide a solar system house heat collecting roof that is simplified in shape and fit, and can be constructed without depending on the skill and experience of the installer.

In order to achieve the above-mentioned object, the roof slab includes a seam fold joint portion, and one roof slab is bent at an end at a substantially right angle, and its tip is bent outward in an L-shape. The first folded portion is formed, and the end portion of the other roof plate is formed with a horizontal folded portion so as to sandwich the first folded portion folded in an outward L shape, and the tip is raised at a right angle. As the second bent portion formed by raising the raised piece, the roof surface is flat without projections , and the helical fold joint portion is housed in a channel-shaped garter that is also used as a base plate. In addition, a substantially M-shaped hanging member having a recess formed in the center is banded on the garter, and the helical fold joint is fixed to the recessed portion of the hanging member that enters the garter, and a roof slope is provided immediately below the roof surface. and an air passage, a base plate for fixing on the retaining clips And summarized in that installed in parallel heat collection glass to exist a gap on a portion of the roof surface by fixing sandwiching the frame of the heat collecting glass pressing plates which can be clamped by screws to the base plate Is.

  According to the first aspect of the present invention, since the roof plate is provided with a helical fold joint portion projecting downward and the roof surface is flat without projections, the sealing is achieved by metallizing all the components. The material can be integrated without using any material, and the distance between the glass and the roof plate can be set as close as possible. As the distance between the glass and the roof plate is closer to heat transfer engineering, the heat collection efficiency increases, so that the heat collection efficiency can be improved as compared with the conventional case.

Further, in addition to the above-described action, the water immersed in the seam fold joint is collected by the channel-shaped garter also serving as a ridge and can be reliably drained without leaking. In addition, by fixing the helical fold joint portion with a substantially M-shaped hanging member having a concave portion at the center, the roof plate can be securely fixed and supported by the hanging member at two places, the upper end of the hanging member and this portion.

Furthermore, the frame of the heat collecting glass can be provided on the suspension simply and stably by sandwiching and fixing the frame between the base plate and the holding plate, and the heat collecting glass can be installed close to the roof plate.

  As described above, the heat collecting roof of the solar system house of the present invention can be constructed without using a sealing material, and when glass is installed on the roof, the distance between the glass and the roof plate is possible. It is possible to increase the heat collection efficiency as close as possible.

  In other words, the conventional heat collecting roof has a structure in which heat collecting glass is installed on a metal roof tile roof that floats from the ground surface by the amount of the heat collecting air layer, or uses a heat collecting panel. In the invention, a flat metal roof that is floated from the field surface by the amount of the heat collecting air layer is obtained.

  In the present invention, the conventional wooden rafters are eliminated and the metal rafters are used, so that the reliability is stable over a long period of time.

  Moreover, the roof shape can be flattened, and a garter for collecting water can be provided at the joint portion of the roof panel to reliably treat rainwater.

  The flattening also simplifies the shape and fit of the accessory serving as a supplementary member for constructing the roof, and can be constructed without depending on the skill and experience of the installer.

  Furthermore, because there is no longer any restriction on the mounting position of the glass due to flattening, a heat collecting glass and a heat collecting plate are used to construct a heat collecting surface with glass by installing a heat collecting glass unit on the roof. This positional relationship can be set to dimensions with an emphasis on heat collecting performance without being determined from the viewpoint of waterproofness required for the roof.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is a longitudinal front view showing one embodiment of a heat collecting roof of a solar system house according to the present invention, and FIG. 2 is an enlarged vertical front view of the main part of the same, in which heat collecting glass is omitted.

  As shown in FIG. 16, the solar heat collection provided on the roof is formed by forming an air flow path 2 having a roof gradient directly below a metal roof plate 1 such as a color iron plate (color galvalume steel plate). One end of the flow path 2 opens as an outside air intake 3 at the eaves or the like (which may be the back of the hut). The lower surface of the air channel 2 is configured as a heat insulating layer. In addition, the case where the roof board 1 is other than metal is also considered.

  In the upper area of the roof, the upper part of the roof plate 1 was covered with the glass 23 with a vertical interval.

  The roof plate 1 is bent at an almost right angle and the entire portion or at least the tip portion of the roof plate 1 is overlapped to project the helical fold joint portion 27 downward, and the roof surface has no projection. It is assumed that the air flow path 2 has a roof slope immediately below the roof surface.

  In the present embodiment, the helical fold joint portion 27 has one roof plate 1 bent at an end substantially at a right angle and bent forward at an L-shape to form a first bent portion 28a. The end portion of the plate 1 is formed with a horizontal folded portion 28c so as to sandwich the first bent portion 28a bent outwardly into an L-shape, and further formed with a rising piece 28d whose tip is raised at a right angle. It was set as the 2nd bending part 28b formed.

  Note that the roof plate 1 is bent at an almost right angle so that the entire portion does not need to be closely overlapped, and may have a slight gap. It is desirable to make it.

FIG. 14 and FIG. 15 show an example. When the first folded portion 28a is sandwiched by the horizontal folded portion 28c due to the relationship between the first folded portion 28a and the second folded portion 28b, FIGS. The bent portions 28f and 28f ′ for forming the ridges may be formed on both sides, and these may be fitted to each other to take into account a change in shape.

  In the figure, reference numeral 29 denotes a garter for both the galvalium steel plate and the like, and an inward horizontal flange 29a is formed on the upper end of the inverted large body.

  Further, in the figure, 30 is a hanging member made of a galvanized steel plate, which is formed by bending a wide band into a substantially M shape as shown in FIGS. 4 and 5 to form a recess 30a in the center, Is horizontally bent outward to form a fixed flange 30b.

  Further, in the figure, 31 is an intermediate support member made of a galvalume steel plate or the like, and the lower end of the laterally U-shaped main body is bent horizontally outward to form a horizontal flange 31a.

  The garter 29 is disposed on the base plate 32, and the garter 29 is fixed by the suspender 30 by banding the suspender 30 on the garter 29 and screwing the fixing flange 30b. At that time, the recess 30 a of the hanging element 30 is accommodated in the garter 29.

  The roof plate 1 is supported at the upper end of the hanging element 30, but the helical folding joint portion 28 a of the roof plates 1 is inserted into the recessed portion 30 a of the hanging element 30 and supported here, and the horizontal portion of the second bent portion 28 b is supported. The entire folding joint portion 27 is fixed by screwing the tip of one piece of the folded portion 28c.

  In this way, the roof plate 1 is supported at an appropriate interval from the lower side by the hanger 30 and the garter 29 arranged at an appropriate interval, but the intermediate support member 31 is arranged and supported by the intermediate portion.

  As shown in FIG. 12, the end of the garter 29 is linked to a gutter 33 provided at the eaves of the roof.

  Next, a heat collecting glass is installed in parallel with a gap on a part of the roof surface. The installation of the glass 23 will be described.

  The glass 23 has a frame 34 as a sash, and a base plate 35 and a press plate 37 that can be fastened to the base plate 35 with a screw 36 are used to sandwich and fix the frame 34.

  The frame 34, the base plate 35, and the presser plate 37 are preferably made of an anodized aluminum extruded product, and the base plate 35 has a hollow rectangular protrusion 35a in the length direction as shown in FIG. The nut 38 is accommodated in the protrusion 35a by welding.

  The holding plate 37 is also a horizontal plate having substantially the same width as the base plate 35, and the base plate 35 is screwed onto the suspension 30 and the frame 34 is sandwiched by screws 36 whose ends are screwed into the nuts 38. The plate 35 and the presser plate 37 are fastened.

  FIGS. 8 and 10 show a case where the frame 34 is fixed only on one side, not on both sides. Instead of the presser plate 37, a metal piece 39 for keraba in which the presser plate and the leg portion 39 a that contacts the base plate 35 are integrated is used.

  FIG. 13 shows an example of a roof. The roof plate 1 is a roof surface in which slits are formed parallel to each other at the joint fold joint 27, and a glass 23 for collecting heat is formed with a gap in a part of the roof surface. Installed in parallel.

  In the figure, reference numeral 40 denotes a solar cell panel for obtaining a power source for driving with the heat collecting fan 7 in the handling box 5 in FIG.

  Thus, the bottom of the roof board 1 becomes the air flow path 2 having the same slope as the roof slope, and the roof board 1 which is a metal plate heated by sunlight warms the outside air that has entered the air flow path 2, and this warming is performed. The generated air rises along the roof slope, and this heated air is collected.

  In the example of FIG. 16, the inside of the falling duct 10 flows down from the handling box 5 and enters the air circulation space 13 between the thermal storage soil concrete 11 and the floor panel 12. In this air circulation space 13, heated air directly warms under the floor via the floor panel 12, stores heat in the thermal storage soil concrete 11, and is blown directly into the room as hot air from the floor outlet. Performs 3 types of heating.

  On the other hand, the water fed from the hot water storage tank 17 through the circulation pipe 16 is heated by the hot water coil 15 and stored as hot water in the hot water storage tank 17, and further hot water is supplied from here through the hot water supply pipes to various places.

  In the heat collection at the roof, the portion where the glass 23 is located has an air layer 2a between the roof surface and can efficiently collect heat without being affected by wind or the like. It can be installed close to the roof plate 1.

  In addition, some rainwater penetrates into the seam fold joint 27 (this seam fold joint 27 is tightly joined and hardly enters), but this is collected in the garter 29 and rain gutter 33. Led to.
