  The present invention relates to an improvement of a solar light utilization system in which solar light utilizing devices such as a solar heat collecting water heater and a solar power generation device are installed on an inclined roof. For example, a base for fixing the solar light utilizing devices is provided. The present invention relates to a waterproof structure when provided on a metal roof.

  2. Description of the Related Art In recent years, a solar power generation apparatus using a solar cell that converts sunlight into light and having a roof of a house or the like as a power generation unit has been widely used. In addition, many solar heat collecting water heaters that convert sunlight into heat have already been used, but various structures have been developed for these solar devices.

  For example, a solar cell module in which a plurality of solar cell elements are connected in accordance with various roof shapes is presented as an example of a solar-powered device attached to a roof. In addition, a solar heat collector that combines and arranges solar cell modules has already been presented.

  And the method of attaching this solar-powered device to the roof has been proposed in various structures.

  For example, a roof integrated solar cell module manufactured integrally with a roof member has been proposed. Moreover, the attachment structure shown in FIG. 11 and FIG. 12 is also proposed.

  FIG. 11 is a partially enlarged cross-sectional view showing a state in which a conventional roof installation frame is arranged on a roof and a photovoltaic power generation array is supported. FIG. 12 is a perspective view schematically illustrating a state in which a conventional photovoltaic power generation array is installed on the roof of a house.

  According to FIG. 12, J is a solar power generation device. In this solar power generation device J, a vertical beam 41 is arranged on the roof 40, and the horizontal beam 41 is arranged on the vertical beam 41 so as to be orthogonal to the direction. There is known an installation method called a roof mounting type in which a crosspiece 42 is arranged, assembled as a frame, and a solar cell module 44 is installed on the horizontal crosspiece 42.

  This installation method will be described in more detail with reference to FIG.

  In the same figure, 39 is a field board which is a structural material which comprises the roof 40, and may further include a rafter. Reference numeral 38 denotes a tile material disposed on the base plate 39. Then, in order to fix the vertical rail 41 to the base plate 39, the wood screw 18 (in addition, a nail is used) and the roof fixing bracket 43 are used.

  That is, the tile material 38 is arranged on the field board 39, the roof fixing metal fitting 43 is further arranged, and the wood screw 18 is joined to the field board 39 through the tile material 38 so that the roof fixing metal element 43 is firmly fixed on the roof. Secure to.

  The vertical rail 41 is fixed on the roof fixing bracket 43.

  However, according to the proposed structure, a hole is formed in the tile material 38 by punching the tile material 38 on the roof 40 and fixing the wood screw 18 or a nail to the structure material of the roof 40. There was a problem that rainwater entered.

  In addition, a method for attaching solar-powered devices as shown in FIG. 13 to the roof has also been proposed.

  As shown in the figure, a metal sheet metal that is a roofing material is formed into a sheet metal 45 that is bent, and a fixing device 47 is disposed at a predetermined portion of a linear protrusion 46 that is generated by the bending. The fixing device 47 has a structure in which the protrusions 46 are sandwiched, and the solar cell module 44 is disposed on the plurality of protrusions 46.

  With such a configuration, the solar cell module 44 can be fixed on the roof without making a hole in the roof.

  Still other attachment methods have been proposed.

  In the mounting method shown in FIG. 13, a metal plate 45 obtained by bending a metal sheet metal is used, but instead of this, even if a metal sheet metal is used in the same manner, the protrusion is formed on the metal roof. In some cases, the shape cannot be 46.

For example, in the tile material 38 shown in FIG. 11 described above, it is difficult to form a sandwich structure. Even in such a structure, it is fixed by being screwed onto a metal roof with screws or nails, and then screw or A configuration has also been proposed in which a cover plate that prevents rainwater from entering the head of the nail is covered (see, for example, Patent Document 1).
JP 09-184264 A

  However, the mounting method described above has the following problems.

   In order to fix the roof fixing bracket on the roof, it is necessary to make a hole in the tile using wood screws and nails, which reduces the waterproof performance of the roof, and rainwater that has penetrated through the hole causes the roof to On the other hand, it caused corrosion.

   In order to prevent such corrosion, it has been proposed that waterproofing technology such as caulking has been proposed, but with this increase in the number of man-hours for construction and further variations in the finish due to the skill level of the operator (waterproof performance Variation). In addition, there is a problem that trouble such as inspection confirmation after work newly occurs.

   In addition, even when the head of a screw or nail is covered with a cover plate that prevents rainwater from entering, the top end of the cover plate is embedded in the lower part of the upper tile, so that most rainwater Can pass over the cover board and improve weather resistance, but on the other hand, there is rainwater flowing in from the lateral direction entering from the gap between the cover board and the tile material, and there is also rainwater blown by the wind, these The problem cannot be resolved.

   Moreover, rainwater may be drawn by the capillarity caused by the gap between the cover plate and the tile material. Moreover, if caulking such as bonding is used to prevent this, there arises a problem such as the variation in the construction finish described above.

   Accordingly, an object of the present invention is to provide a high-quality sunlight utilization system that prevents rainwater from entering the roof when installing the sunlight utilization device on an inclined roof.

   Another object of the present invention is to provide a solar system that can improve waterproofing performance against roofs and reduce construction costs without performing waterproofing such as caulking, with simple construction.

   Still another object of the present invention is to provide a highly reliable solar light utilization system free from variations in waterproof performance.

  The present invention is a solar-use system in which a roof installation frame for installing a solar-powered device is disposed on an inclined roof, and the solar-powered device is fixed by the roof-installation frame, and the roof installation frame Comprises a waterproof cover including a lower cover body and an upper cover body having a through hole, and fixing means for installing the waterproof cover on the roof. The fixing means includes a plate-like body and the plate. A bar-like support part for fixing the rod-like body to the roof, and a fastening member attached to the bar-like support part that is passed through the through hole so as to be pressed against the upper surface of the upper cover part. On the other hand, in the rain water flowing down on the roof, a water stop channel is formed to prevent the rainwater flowing toward the plate-like body.

  Another solar light utilization system of the present invention is characterized in that the water stop is in contact with the roof.

  According to the solar light utilization system of the present invention, as described above, the roof installation frame is provided with a waterproof cover including a lower cover body and an upper cover body having a through hole, and the waterproof cover is installed on the roof. The fixing means includes a plate-like body, a rod-like support portion that fixes the plate-like body to the roof, and the rod-like shape that is passed through the through hole so as to press against the upper surface of the upper cover portion. It consists of a fastening member attached to the support part, and further, with respect to the lower cover body, among the rain water flowing down on the roof, in order to prevent the part toward the plate-like body, by forming a water stop channel, As a result, it becomes the structure which prevents it also with respect to the blowing of rain from the rain water side part (side) which flows down on a roof. In addition, there is an advantage that rainwater is not drawn by capillary action.

  Furthermore, the effect can be further heightened by abutting the water stop on the roof.

  Further, according to the present invention, by using the fastening means by the combination of the plate-like body, the rod-like support portion and the fastening member, and the lower cover body in which the water stop passage is formed, the step of fastening with the fastening member, Since it can be easily installed, the water stoppage performance is not affected by the skill level of the operator, and without this, waterproofing such as caulking is not performed, and the waterproof performance against the roof can be improved with simple construction. A reduced high quality and high reliability solar power system can be obtained.

  Further, in the solar light utilization system of the present invention, by tightening the water stop channel with a tightening member so as to contact the roof, for example, by tightening the tightening member beyond a certain predetermined value, The outer edge of the lower cover body moves upward with the waterway in contact with the roof as a fulcrum, and its deformation may cause deflection on the roof. Even if it exists, the space | gap between a low part cover body and a roof surface can be ensured.

  Furthermore, about the low part cover body which formed the water stop path mentioned above, the water stop performance can be improved by making it various other structures.

  For example, with respect to the end of the waterway, or the auxiliary waterway where the end is branched, by arranging them so as to surround the periphery of the fixing member, against the blowing of wind and rain from the eave direction and from the left and right perpendicular to it Further, the water stop performance can be enhanced.

  Hereinafter, the solar light utilization system of the present invention will be described in detail by taking as an example the case where the solar light utilization device is a solar power generation device.

(Example 1)
Hereinafter, an embodiment of the waterproof structure in the roof mounting frame according to the solar power generation device will be described based on the drawings schematically shown.

  FIG. 1 is a perspective view showing a state where a roof mounting frame is attached on an inclined roof, and FIG. 2 is a perspective view showing an assembled state thereof.

  FIG. 3 is a partially enlarged cross-sectional view showing the state of assembling the vertical and horizontal solar cell modules, and FIG. 4 is a partially enlarged cross-sectional view for explaining how the water stop structure is formed.

  As shown in FIG. 1, according to the waterproof structure of the roof mounting frame of the present invention, the fixing bracket 5 that is the fixing means includes a rod-like support portion 6, a fixing portion 7 that is the plate-like body, and tightening. It consists of member 8.

  The waterproof cover 1 including the lower cover body 2, the upper cover body 3, and the through-hole 4 provided in the upper cover body 3 is disposed on the fixing metal 5 so as to cover it.

  Then, by passing the rod-like support portion 6 through the through hole 4 and fastening and fixing with the fastening member 8, the water stop passage 9 provided in the lower cover body 2 is brought into close contact with the roof, Become.

  A more specific configuration will be described.

  Although the configuration shown in FIG. 11 has been exemplified as a conventional technique, according to the present invention, the fixing bracket 5 is fixed on the tile material 38 (metal roof material arranged on the roof) used there. Good.

  As shown in FIG. 1, a screw hole 10 through which a wood screw or a nail is passed is provided in the fixing portion 7 of the fixing metal 5, and a wood screw or a nail is driven into the hole 10 to fix the tile material 38 together with the structural material of the roof.

  On the other hand, the fixing bracket 5 is provided with a bar-like support portion 6 for supporting a vertical beam or the like facing upward. The rod-like support portion 6 is passed through the through hole 4 of the waterproof cover 1, and The fastening part 8 is attached.

  The fixture 5 is made of a metal plate such as iron or stainless steel, and has a good weather resistance so that the support strength does not decrease due to wind and rain over a long period of time.

  In this example, the rod-like support portion 6 is threaded, and on the other hand, the fastening member 8 can be fastened and fixed using a nut.

  It should be noted that the tightening member 8 may be a push nut to eliminate the need for threading the rod-like support portion.

  The waterproof cover 1 can be a pressed product of sheet metal such as iron or stainless steel or a resin molded product such as polycarbonate.

  For the material, sheet metal is excellent in weather resistance, and resin is selected so as not to cause electric contact with the metal roof, and is used in accordance with each advantage.

  In this example, description will be made using a sheet metal product obtained by pressing an iron plate.

  The waterproof cover 1 includes a bottom cover body 2 and an upper cover body 3, and the upper cover body 3 may have a height that prevents the fixing bracket 5 from hitting the back surface of the waterproof cover 1. Considering the flow, it is better to have a certain level difference rather than the highest height according to the height of the fixed portion 7. According to experiments conducted by the present inventor, the height of the upper cover 3 is at least about 1 cm in consideration of the inclination angle of the roof of a general house and the flow velocity of rain flowing down there. In this way, the rainwater is divided into right and left by the wall surface caused by the difference in height like the flow of rainwater of FIG. 5 described later, so that the rainwater does not flow to the upper part of the upper cover 3, and the through hole It is preferable that rainwater enters from 4 to the inside.

  Since the rod-like support portion 6 of the fixing metal 5 is removed from the through hole 4 of the upper cover body 3, basically only the height of the fixing portion 7 is required.

  However, in consideration of the flow of rainwater, it is better to have a certain level of difference than to make it lower according to the height of the fixed portion 7.

  According to the experiment conducted by the present inventor, rainwater intrusion was less when the height was about 1 cm.

  On the other hand, the lower cover body 2 is provided with a water stop passage 9 protruding toward the roof surface, and the water stop passage 9 having such a groove structure is provided so as to surround the outer periphery of the upper cover body 3, and the eaves of the roof Only the side (direction A) is open.

  FIG. 2 shows a state in which, after passing through the through hole 4 of the waterproof cover 1 through the rod-like support portion 6 of the fixture 5 as described above, the fastening member 8 is attached to the rod-like support portion 6 and fastened and fixed. .

  In addition, it is more preferable that a waterproof washer or a waterproof packing 11 is bitten between the tightening member 8 and the waterproof cover 1 to further enhance the waterproof so as to prevent the peeling of the sheet metal. .

  Next, changes in the tightening state of the tightening member 8 due to the use of the fixing bracket 5 will be described with reference to FIGS.

  FIG. 2A is a cross-sectional view showing a state before the tightening member 8 in the state of FIG. 2 is tightened. FIG. 2B is a cross-sectional view showing a state after the tightening member 8 in the state of FIG. 2 is tightened. 4 (a) and 4 (b) are both cross-sectional views seen from the eaves side direction (A) shown in FIG.

  As shown in FIG. 4A, when the fastening member 8 is free on the support portion 6, the waterproof cover 1 is only covered on the mounting bracket 5. There is a gap between them.

  On the other hand, as shown in FIG. 4 (b), when the tightening member 8 is tightened, the waterproof cover 1 is pressed down and the water stop passage 9 at the bottom of the waterproof cover 1 comes into contact with the roof tile 38 and further adheres. To do.

  In such a configuration, a gap 12 is generated between the lower cover body 2 of the waterproof cover 1 and the roof tile 38, so that rainwater blown from the left and right does not stay with the surface tension, or due to capillary action. The rainwater is not drawn in.

  According to an experiment conducted by the present inventor, it was confirmed that when it is installed on an inclined metal roof, it should be set to 2 mm or more as a suitable gap distance that does not cause rainwater retention and capillary action.

  When the gap cannot be secured to 2 mm or more due to roof deflection or the like, in this device, the waterproof cover 1 is further crushed and deformed by tightening the tightening member 8 to a specified level or more. By utilizing such deformation, the inner peripheral side of the lower cover body 2 is pushed downward (indicated by arrow B in FIG. 4) from the water stop path 9 serving as a fulcrum of the deformation on the bottom surface, and reversely The outer peripheral side moves upward (indicated by an arrow C in FIG. 4), and as a result, the gap 12 is increased and an optimum gap distance can be obtained.

  Note that the degree of deformation varies depending on the material, thickness, and height of the water stop channel of the water stop cover 1, and therefore, it is preferable to design in advance according to the degree of deflection of the roof.

  As a method for defining the tightening position, for example, as shown in FIG. 3, a nut 11 for defining the tightening position of the waterproof cover 1 to the roof may be disposed on the rod-like support portion 6. The attaching member 8 cannot be tightened any more, and as a result, over-tightening is unlikely to occur, and the nuts are firmly tightened with each other, so that the effect of preventing the tightening member 8 from being loosened can be obtained. When the gap is insufficient due to the roof deflection described above, the position of the nut 11 may be lowered.

  Thus, as shown in FIGS. 1, 2, and 4, FIG. 3 shows a case where the mounting method described above is applied to a solar power generation device.

  That is, as shown in FIG. 3, a vertical beam 41 is supported by a bar-like support portion 6 on a roof installation base S composed of a fixing bracket and a waterproof cover fixed on the roof 40, and on the vertical beam 41. The horizontal beam 42 is fixed so as to be orthogonal, a large number of solar cell modules 44 are mounted on the horizontal beam 42, and the photovoltaic power generation array is completed on the roof.

  As mentioned above, although the solar power utilization system of this example was demonstrated with the case where the solar power utilization apparatus is a photovoltaic power generation device (solar power generation array), it replaces with this and the solar radiation utilization apparatus is solar thermal collection. Even if it is a hot water heater (solar heat collection array), the roof installation stand based on this invention is applicable.

  Next, the movement in a state in which a photovoltaic power generation array, a solar heat collection array, or the like is supported as the roof mounting base S will be described.

  FIG. 5 and FIG. 6 both show the state of rainwater flowing through the roof mounting base S when it rains.

  FIG. 5 is a partially transparent plan view of the rainwater flowing between the roof mounting base S and the roof surface as seen from above. FIG. 6 is a perspective view schematically showing the state of rainwater flowing on the upper surface of the roof mounting frame.

  In these figures, the top is the roof ridge side and the bottom is the eaves side.

  As shown in FIG. 5, rainwater 20 that has flowed on the roof enters between the roof surface (tile material) and the roof installation base S, but is blocked by the water stop 9 and changes the course in the lateral direction. .

  At this time, if the water stop channel 9 is inclined to the left and right as shown in the figure so that the rainwater can be distributed to the right and left without resistance, the pressure of the rainwater flow can be relieved. Stress can be reduced, which is preferable.

  Further, the rainwater 21 poured from the left and right by wind or the like is similarly changed in the course by the water stop 9. As a result, the rainwater does not enter the fixing bracket portion of the roof mounting base S.

  Even if there is a blow through the lower opening 15 where the waterway 9 is interrupted, the opening 15 is on the eave side of the roof, so rainwater is pulled back by gravity and discharged from the opening 15. As a result, the fixing bracket portion of the roof mounting base S is hardly wetted.

  On the other hand, on the front side of the roof mounting base S, as shown in FIG. 6, the rainwater 20 is distributed to the left and right by the wall formed by the step between the lower cover body 2 and the upper cover body 3, and most of the rainwater 20 is on the lower cover body 2. Flowing.

  At this time, when the waterproof cover 1 is made of metal press molding or the like, the portion of the water stop portion 9 becomes a groove, so that the rain water 20a when the amount of rain water is small reaches the water stop before reaching the wall. It is guided to a groove formed on the surface side of the portion 9 and discharged.

  Conversely, a large amount of rainwater 22 that gets over the walls (steps) flows down on the upper cover body 3 as it is, but may enter the through hole 4 with a small amount. Also in this case, water droplets accumulated by the opening 15 and vaporized vapor can be discharged smoothly, so that damage to the fixing bracket portion of the roof mounting base S can be minimized.

  Next, another embodiment according to the present invention will be described with reference to the drawings schematically shown.

(Example 2)
According to this example, as shown in FIG. 7, on the upper surface of the upper cover body 3 of the roof mounting base S, a step is provided one step higher than the periphery 3a of the through hole 4 through which the rod-like support portion 6 is passed. .

  In this way, by providing a step on the upper surface of the upper cover body 3, even if rainwater rides on the upper cover body 3 when there is a large amount of rainwater flowing on the roof, it is necessary to overcome the step again. Therefore, it is possible to more advantageously prevent rainwater from entering the inside through the through hole 4.

(Example 3)
According to this example, as shown in FIG. 8A, the eaves-side end portions 9a and 9b of the water stop channel 9 are bent inward to counter the inflow of rainwater from the lower side (eave side). In this case, in the case of the wide opening 15 as described in FIG. 5, the distance (length) necessary for rainwater entering by wind blowing to start descending again against the roof inclination is set. Whereas it is necessary to provide the eaves side of the lower cover body 2 as a warped portion, the eaves side ends 9a and 9b of the water blocking passage 9 physically block the blowing itself, so that the lower cover body 2 The eaves side can be shortened, contributing to downsizing. In addition, for example, at this time, the end portion 9b is extended to the outside longer than the end portion 9a, and the opening portion 15a is secured between the end portions 9a-9b, thereby preventing rainwater from entering and simultaneously entering the inside. Water droplets and steam can be discharged.

  In this example, the end 9b is extended outward longer than the end 9a. Alternatively, the end 9a may extend outward longer than the end 9b.

(Example 4)
According to this example, as shown in FIG. 8 (b), the end of the water stop channel 9 is directly penetrated to the eaves side, and the auxiliary water stop channels 9 c and 9 d are extended from the middle of the water stop channel 9. Also good.

  By adopting such a configuration, resistance to rainwater blowing from the side is improved. Further, when the amount of rainwater is small, water droplets can flow along the still water channel 9.

(Example 5)
According to this example, as shown in FIG. 9, a second water stop channel 19 having a similar structure may be provided on the outer periphery of the water stop channel 9 to improve the waterproof performance as a double structure.

  In addition, according to this example, it is possible to compensate for a location where the close contact with the roof surface cannot be maintained by the waterway 9 alone due to the distortion of the roof or the like.

  Furthermore, even if the second water stop channel 19 does not maintain close contact with the roof surface, the rainwater blown in can be decelerated or the surface tension of rainwater can be used to obtain a water stop effect. There is an effect of ensuring the water stoppage of the water stop channel 9.

(Example 6)
In this example, as shown in (Example 5), an example of a cross-sectional shape of the water stop cover 1 having the second water stop passage 19 is shown.

  FIG. 10A shows a cross-sectional view of the water stop cover 1 having the second water stop passage 19.

  According to this example, as described above, the second water stop channel 19 does not necessarily need to be in close contact with the roof surface. You may make it not inhibit the adhesiveness of.

(Example 7)
In this example, as shown in FIG. 10B, if the water stop channel 9 has a sharp tip, the contact pressure on the roof surface is concentrated locally, so that the adhesion to the flat roof surface is improved. .

(Example 8)
In this example, as shown in FIG. 10 (c), in the cross section, if the water stop channel 9 is a semicircular or semi-elliptical shape having a curved surface, the roof surface is distorted vertically. Any position on the curved surface of the water stop channel 9 can be in contact with the roof surface to ensure a contact point, thereby improving the adhesion to the roof distortion.

(Example 9)
Furthermore, in this example, as shown in FIG. 10 (d), the water stop member 29 may be attached to the lower part of the waterproof cover 1 with the water stop protrusion as a separate body.

  In this case, since the material can be changed only for the water stop member 29, it is easy to change to a water stop structure corresponding to the distortion state of the roof such as rubber or packing.

  Further, if a magnet is used for the water stop member 29, it is possible to assist the pressing by only the fastening member of the roof mounting base, and it is possible to automatically follow the change in distortion accompanying the secular change of the roof.

   As described above, according to the present invention, when the fastening member 8 is tightened, the waterproof cover 1 is pressed down and lowered, and the water stop channel 9 at the bottom of the waterproof cover 1 is in close contact with the roof tile 38, so The gap 12 is formed between the head cover body 2 and the roof tile 38 so that rainwater blown from the left and right does not stay with surface tension, and the rainwater is not drawn by capillary action. The drainage was made compatible.

  In addition, rainwater that has entered from the through hole 4 can smoothly discharge water droplets and vaporized vapor collected by the opening 15, so that damage to the fixing bracket portion of the roof mounting base S can be minimized.

  Further, the eaves-side ends 9a and 9b of the eaves stop channel 9 are bent inward to improve the water-stopping performance against rainwater blown from below (eaves side), and the eave side length of the lower cover body 2 is improved. The length can be shortened, contributing to downsizing.

  Furthermore, the second water stop channel 19 having the same structure is provided on the outer periphery of the water stop channel 9 to improve the waterproof performance by using a double structure, and only the water stop channel 9 due to distortion of the roof and the like Can make up for places that cannot keep close. Further, the second water stop channel 19 can reduce the rainwater blown in even if the close contact with the roof surface is not maintained, and can obtain a water stop effect by utilizing the surface tension of the rainwater. Water can be made certain.
