(Embodiment 1)
An outline will be described before the embodiment is specifically described. The present embodiment relates to installation of a solar cell module on a decorative slate tile roof. So far, the construction of the solar cell module has been made regardless of the pitch of the decorative slate tile roof, and therefore the design of the entire roof on which the solar cell module is installed has been lowered. In addition, when installing one solar cell module, it is necessary to fix the solar cell frame and the pedestal frame with screws at four locations, which increases the number of man-hours for installation and makes it difficult to install the solar cell module. . Furthermore, since a screw | thread may be arrange | positioned in the area | region between adjacent solar cell modules, since a clearance gap arises between solar cell modules, while the design property falls, the number of solar cell modules which can be installed reduces.

  In order to cope with these, in this embodiment, a solar cell module having a size related to the size of the decorative slate roof tile is used. In addition, hooks for engaging the eaves-side solar cell module and hooks for engaging the ridge-side solar cell module stand separately on the fixture used when installing the solar cell module. Established. The solar cell module and the hook are only directly engaged with each other, and it is not necessary to fix the solar cell module using screws. Furthermore, since the fixture is composed of two stages, and each hook is erected on each stage, the gap between the eaves-side solar cell module and the ridge-side solar cell module is reduced.

  According to this embodiment, the eaves side engagement hook for engaging the eaves side solar cell module and the ridge side engagement hook for engaging the ridge side solar cell module are provided independently. Therefore, the construction of the solar cell module can be facilitated. In addition, since the eaves side engaging hook and the ridge side engaged portion are engaged and the ridge side engaging hook and the eave side engaged portion are merely engaged, the number of construction steps can be reduced. Moreover, since the number of construction steps is reduced, the maintainability can be improved. Moreover, since the size of the solar cell module is determined according to the size of the decorative slate tile roof, the design can be improved.

  Also, since the eaves side engagement hook and the ridge side engagement hook are erected on the lower step surface and the upper step surface of the staircase shape, the space between the eaves side solar cell module and the ridge side solar cell module is increased. You can get closer. Moreover, since the space | interval of the solar cell module by the eaves side and the solar cell module by the ridge side can be closely approached, designability can be improved. Moreover, since the space | interval of the solar cell module on the eaves side and the solar cell module on the ridge side can be made close, the number of solar cell modules that can be installed can be increased. Moreover, since the fitting hole which fits a wedge is provided, a solar cell module can be fixed. Moreover, since it only fits a wedge, construction can be facilitated.

  Further, since the position of the fixture to be installed next is determined using the solar cell module already fixed to the fixture, it is possible to omit the marking of the fixture to be installed next. Further, since the marking of the fixture to be installed next is omitted, the solar cell module can be easily constructed. Moreover, since the solar cell frame and the gantry frame are not fixed using screws when the solar cell module is installed, the solar cell module can be easily installed. In addition, since the wedge fitted to the fixture is separated by another wedge, the wedge can be removed only by the wedge without using another tool. Moreover, even if there is no separate tool, the wedge can be detached only by the wedge, so that the maintainability can be improved.

(Embodiment 2)
Next, a second embodiment will be described. In the second embodiment, the solar cell module shown in the first embodiment will be described in more detail. The configuration of the solar cell module according to Embodiment 2 is the same as the configuration of the solar cell module according to Embodiment 1. Below, it demonstrates focusing on the part which is not demonstrated in Embodiment 1. FIG.

  FIGS. 15A to 15C show the configuration of the solar cell module 10. FIG. 15A is a top view of the solar cell module 10, which is shown in the same manner as FIG. The solar cell module 10 includes a ridge side frame 22, an eaves side frame 24, a first short side frame 34a, a second short side frame 34b, and a solar cell panel 110, which are collectively referred to as a short side frame 34. Solar cell panel 110 includes a plurality of solar cells 112.

  The ridge side frame 22, the eaves side frame 24, the first short side frame 34a, and the second short side frame 34b are formed of, for example, aluminum, iron, stainless steel, resin, or the like, and are formed by extrusion molding or the like. The first short side frame 34 a and the second short side frame 34 b are provided along a pair of short sides of the solar cell panel 110, and the ridge side frame 22 and the eaves side frame 24 are a pair of solar cell panels 110. It is provided along the long side. The ridge side frame 22 or the eaves side frame 24 and the short side frame 34 are connected to each other at the end points in the longitudinal direction, thereby protecting the solar cell panel 110. Here, the solar cell panel 110 is fitted into the ridge-side frame 22, the eaves-side frame 24, the first short-side frame 34a, and the second short-side frame 34b by using a sealing material at the periphery. As the sealing material, for example, silicone resin, butyl rubber, epoxy resin, and urethane resin are used.

  The solar cell panel 110 is formed in a substantially rectangular shape when viewed from the upper surface direction. In solar cell panel 110, a plurality of solar cells 112 are electrically connected to each other by a wiring material made of a conductive material such as copper foil. Further, the plurality of solar cells 112 are light-transmitting materials such as EVA (ethylene vinyl acetate) having excellent weather resistance and moisture resistance between the light-transmitting front surface member and the back surface member made of a weather-resistant film. It is sealed with a sealing material having properties. Moreover, the several solar cell 112 connected in series by the wiring material comprises the strings which are 1 unit units. The strings are connected by connection wiring. Furthermore, a lead wire (not shown) for drawing the output from the solar cells 112 to the outside is connected. For example, a crystalline semiconductor composed of single crystal silicon or polycrystalline silicon is used for the solar cell 112, but the present invention is not limited to this, and other solar cells may be used. A terminal box (not shown) is provided on the back surface of the solar cell panel 110.

  FIG.15 (b) is sectional drawing of the B-B 'direction of the solar cell module 10 of Fig.15 (a), and this is shown similarly to FIG.2 (b). In FIG. 15B, the upper surface of the solar cell panel 110 corresponds to the front surface, and the lower surface of the solar cell panel 110 corresponds to the back surface. The eaves side holding portion 28 in the eaves side frame 24 and the ridge side holding portion 26 in the ridge side frame 22 are opened to the solar cell module 10 side in common. The peripheral edge portion of the solar cell panel 110 is fitted into the eaves side holding portion 28 and the ridge side holding portion 26. Therefore, the eaves side holding part 28 and the ridge side holding part 26 are equivalent to a fitting part. A first surface 122 and an upper side surface 136 are disposed opposite to each of the eaves side holding portion 28 and the ridge side holding portion 26. The first surface 122 is in contact with the back surface of the solar cell panel 110, and the upper side surface 136 is in contact with the surface of the solar cell panel 110. The solar cell panel 110 is fitted into each of the eaves side holding portion 28 and the ridge side holding portion 26 by the contact of the solar cell panel 110 on the first surface 122 and the upper side surface 136.

  The main body 120 in each of the eaves side frame 24 and the ridge side frame 22 is positioned below the eaves side holding portion 28 and the ridge side holding portion 26, and also the eave side holding portion 28 and the ridge side holding portion 26. Rather than the solar cell panel 110. The main body 120 has a hollow structure having an opening 128 formed in the inner direction of the solar cell panel 110. A second surface 124 that contacts the back surface of the solar cell panel 110 is disposed on the solar cell panel 110 side of the main body 120. The second surface 124 is formed integrally with the first surface 122. Furthermore, a third surface 126 extending from the second surface 124 toward the inner side of the solar cell panel 110 is disposed. The third surface 126 faces away from the back surface of the solar cell panel 110. Therefore, a staircase shape is formed in which the first surface 122 and the second surface 124 are on the upper stage, and the third surface 126 is the lower stage.

  FIG. 15C is a cross-sectional view of the short side frame 34, which is shown in the same manner as FIG. The short side frame 34 includes a short side holding part 36 instead of the eaves side holding part 28 and the ridge side holding part 26. Similar to the eaves side holding portion 28 and the ridge side holding portion 26, the short side holding portion 36 includes a first surface 122 and an upper side surface 136. Moreover, the main-body part 120 is arrange | positioned with respect to the short side side clamping part 36 similarly to Fig.15 (a), (b).

  16 (a)-(b) show the action of force when a load is applied to the solar cell module 10 of FIGS. 15 (a)-(c). FIG. 16 (a) is shown in the same manner as FIG. 15 (b), and FIG. 16 (b) is shown in the same way as FIG. 15 (a). Here, as shown in FIG. 16A, it is assumed that a downward load 138 is applied to the surface of the solar cell panel 110. As described above, since the solar cell panel 110 is fitted into the eaves side holding portion 28 and the ridge side holding portion 26, a downward force is applied to the eaves side frame 24 and the ridge side frame 22 as well. In particular, a downward force is applied to the first surface 122 and the second surface 124. This force acts on an intermediate position of the first surface 122 and the second surface 124 from the peripheral edge of the solar cell panel 110 toward the center. This acting force is shown in FIG. 16 (a) as a downward arrow.

  On the other hand, the center of gravity of the eaves side frame 24 and the building side frame 22 in the cross-sectional view shown in FIG. In FIG. 16 (a), the center of gravity 130 is not a structure, but indicates the position of the center of gravity of the eaves side frame 24 and the building side frame 22 shown in FIG. 15 (a). Shown using a hanger. The center of gravity 130 exists in the inner direction of the solar cell panel 110 than the above-described intermediate position. Due to the presence of the center of gravity 130, a force in the inner direction of the solar cell panel 110 is applied to the eaves side frame 24 and the ridge side frame 22 in accordance with the downward force described above. This force is shown as an inward arrow in FIG. That is, with respect to the load 138 from the surface of the solar cell panel 110, the eaves side frame 24 and the building side frame 22 are not easily applied with a force to bend the outside of the solar cell module 10, and are a force to bend to the inside. Will be added. Such a force is also shown as a dotted line in FIG. The solar cell panel 110 is unlikely to fall off the eaves side frame 24 and the ridge side frame 22 due to the force of bending inward. The same applies to the first short side frame 34a and the second short side frame 34b.

  FIG. 17 shows a configuration when a load is applied to the frame 200 to be compared. The frame 200 corresponds to the ridge side frame 22, the eaves side frame 24, and the short side frame 34, and FIG. 17 shows a cross-sectional view. The frame 200 includes a holding part 202 and a main body part 204. The holding part 202 corresponds to the ridge side holding part 26, the eaves side holding part 28, and the short side holding part 36, and the main body part 204 corresponds to the main body part 120. The sandwiching part 202 has a hollow structure, and the main body part 204 is located on the upper part of the sandwiching part 202. Therefore, the relative positional relationship in the horizontal direction between the holding portion 202 and the main body portion 204 is different from the conventional one. A load 208 that is a downward force is applied to the main body 204. On the other hand, the position of the center of gravity of the frame 200 is outside or at the same position as the point of application of the load 208 from the frame 200. As a result, a force that tends to bend outward is easily applied to the frame 200, and the solar cell panel is easily detached from the frame 200.

  FIG. 18 shows the connections between the frames shown in FIGS. 15 (a)-(c). As described above, the ridge side frame 22 or the eaves side frame 24 and the short side frame 34 are connected to each other. In FIG. 18, the connection of the eaves side frame 24 and the 2nd short side frame 34b is demonstrated among those connections. The corner piece 132 is a connecting member having an L-shape, and includes a hook-shaped portion 140 on inner portions of both sides. The corner piece 132 is made of aluminum. For example, one side of the L-shape of the corner piece 132 is inserted into the second short side frame 34b. Following this, the other side of the L-shape of the corner piece 132 is inserted into the eaves side frame 24.

  19 (a)-(b) shows a configuration when a corner piece is inserted into the frame shown in FIGS. 15 (a)-(c) and the frame shown in FIG. FIG. 19A is a cross-sectional view of the frame 200 and is shown in the same manner as FIG. The corner piece 210 is press-fitted and fixed to the main body 204. The corner piece 210 is sandwiched between both walls of the main body 204. Therefore, the pressure of the corner piece 210 is likely to be applied in the outer direction and the inner direction. When pressure is applied to the outer wall of the main body 204, the outer wall may bulge.

  FIG. 19B is a cross-sectional view of the eaves side frame 24 and is shown in the same manner as FIG. The corner piece 132 is press-fitted and fixed to the main body 120. Although a wall exists outside the main body 120, an opening 128 is formed inside the main body 120, so there are many areas where no wall exists. Therefore, the eaves side frame 24 and the like are reduced in weight, and the solar cell module 10 is also reduced in weight. In addition, since the conventional corner piece can be used as the corner piece 132, the present manufacturing method of a corner piece is maintained. Further, even when pressure is applied to both walls of the main body 120 due to the press-fitting of the corner piece 132, the pressure of the corner piece 132 is easily released to the inside with a small rigidity. Therefore, the pressure on the outer wall of the main body 120 is suppressed, and the bulge that can occur on the outer wall is suppressed. As a result, appearance abnormality due to swelling is improved. Such a situation is the same for the ridge side frame 22 and the short side frame 34.

  20 (a)-(d) show the manufacturing procedure of the solar cell module 10 of FIGS. 15 (a)-(c). FIG. 20A is a cross-sectional view of the short side frame 34 and is shown in the same manner as FIG. Note that the same procedure may be executed for the ridge side frame 22 and the eaves side frame 24, but here, the procedure for the short side frame 34 will be described. In FIG. 20B, the silicone resin 134 is applied across the second surface 124 and the third surface 126. A dispenser is used to apply the silicone resin 134. The silicone resin 134 may be applied to the first surface 122, but the silicone resin 134 is not applied to a portion of the first surface 122 that faces the upper surface 136. This corresponds to the silicone resin 134 being applied only to the right side portion of the first surface 122 in FIG.

  In FIG. 20C, the solar cell panel 110 is fitted into the short side holding portion 36 of the short side frame 34 in order to attach the short side frame 34 to the solar cell panel 110. In FIG. 20 (d), when the solar cell panel 110 is fitted into the short side holding portion 36, the silicone resin 134 flows and diffuses between the short side holding portion 36 and the solar cell panel 110. The The third surface 126 and the solar cell panel 110 are separated from each other than between the second surface 124 and the solar cell panel 110. Therefore, excess silicone resin 134 is accumulated between the third surface 126 and the solar cell panel 110. Since excess silicone resin 134 is stored, the amount of silicone resin 134 applied is increased and the adhesion area of the back surface of solar cell panel 110 is increased. Further, since the first surface 122 facing the upper side surface 136 is not coated with the silicone resin 134, the amount of the silicone resin 134 protruding from the upper side surface 136 is reduced or the silicone resin 134 does not protrude from the upper side surface 136. .

  FIGS. 21A to 21D show a manufacturing procedure to be compared with the solar cell module 10 of FIGS. 15A to 15C. FIG. 21A is also a cross-sectional view of the short side frame 34, as in FIG. In FIG. 21B, a silicone resin 134 is applied to the first surface 122, particularly the portion facing the upper surface 136. In FIG. 21C, the solar cell panel 110 is fitted into the short side holding portion 36 of the short side frame 34 in order to attach the short side frame 34 to the solar cell panel 110. In FIG. 21 (d), the silicone resin 134 is diffused between the short side holding portion 36 and the solar cell panel 110 by fitting the solar cell panel 110 into the short side holding portion 36. As illustrated, the silicone resin 134 protrudes from the upper side surface 136. In particular, as the area of the upper side surface 136 decreases, the amount of the silicone resin 134 that protrudes from the upper side surface 136 increases.

  Hereinafter, in the situation where the solar cell module 10 having the configuration shown in FIGS. 15A to 15C, that is, the configuration shown in FIGS. 2A to 2C, is installed on the decorative slate tile roof 12, rainfall, snowfall, etc. The case where moisture accumulates inside the solar cell module 10 will be described. Here, moisture easily accumulates inside the main body of the frame in the solar cell module 10, and when the accumulated moisture freezes, deformation of the frame or the like occurs. In order to suppress this, the bottom surface of the frame is punched with a press die, but the number of manufacturing steps increases, and the cost increases due to the die cost and processing cost.

  In the solar cell module 10 according to the present embodiment, with the configuration described so far, moisture that has entered the inside of the main body of the frame is discharged to the outside even if the hole is not drilled into the bottom surface of the frame. Here, draining will be described with reference to FIGS. 22 (a)-(c) shows the outline of draining in the solar cell module 10 in FIGS. 15 (a)-(c). The configuration of the solar cell module 10 shown in FIGS. 22A to 22C is the same as that of FIGS. 15A to 15C and FIGS. 2A to 2C. For the sake of clarity, in FIG. 22B, the main body 120 in FIG. 15B is shown as a ridge-side main body 150 and an eaves-side main body 152, and in FIG. The main body 120 in FIG. The ridge-side main body 150 is included in the ridge-side frame 22, and the eaves-side main body 152 is included in the eaves-side frame 24. Further, the short side main body 154 is included in the short side frame 34. Further, FIG. 22C shows a hollow portion 156, an inner wall 158, and an outer wall 160.

  In FIG. 22A, the ridge side long side part 14 and the eaves side long side part 16 are arranged in parallel, and the first short side part 18 and the second short side part 20 are arranged substantially in parallel. Further, the ridge-side long side portion 14 and the eaves-side long side portion 16 are disposed substantially perpendicular to the first short side portion 18 and the second short side portion 20. Abbreviation means that it includes a range of errors. Further, it can be said that the first short side portion 18 and the second short side portion 20 are adjacent to the ridge side long side portion 14 and the eaves side long side portion 16. When the solar cell module 10 is installed on the decorative slate tile roof 12, the ridge-side long side portion 14 is higher than the eaves-side long side portion 16. Therefore, the moisture that has entered the first short side frame 34a and the second short side frame 34b flows in the direction of the arrow in the figure, that is, in the direction of the eaves side long side portion 16. Moreover, the flowed water is discharged from the eaves side frame 24 attached to the eaves side long side 16 side. Details of the water discharge will be described with reference to FIGS.

  FIG.22 (b) is sectional drawing of the C-C 'direction of the solar cell module 10 of Fig.22 (a). The ridge side long side portion 14 of the solar cell module 10 is fitted into the ridge side holding portion 26 of the ridge side frame 22. The ridge-side main body 150 is provided below the ridge-side holding portion 26. The ridge-side engaged portion 30 is provided below the ridge-side main body 150 and opens in the inner direction of the solar cell module 10. That is, the ridge-side engaged portion 30 extends downward from the outer end of the bottom surface of the ridge-side main body 150 and then bends inward. On the other hand, the eaves side long side part 16 of the solar cell module 10 is fitted into the eaves side holding part 28 in the eaves side frame 24. The eaves side main body 152 is provided on the lower side of the eaves side holding portion 28. The eaves-side engaged portion 32 is provided below the eaves-side main body portion 152 and opens in the outer direction of the solar cell module 10. That is, the eaves-side engaged portion 32 extends downward from the inner end of the bottom surface of the eaves-side main body 152 and then bends outward.

  FIG. 22C is a cross-sectional view of the short side frame 34. The first short side portion 18 or the second short side portion 20 of the solar cell module 10 is fitted into the short side holding portion 36 of the short side frame 34. The short side main body 154 is provided below the short side holding portion 36. In the lower part of the short-side main body 154, an inner wall 158 and an outer wall 160 are juxtaposed upward from the bottom along the first short side 18 or the second short side 20 (not shown). Furthermore, a space sandwiched between the inner wall 158 and the outer wall 160 becomes a hollow portion 156. Due to such a configuration, moisture that has entered the short-side main body 154 tends to accumulate in the hollow portion 156.

  The length in the vertical direction of the short side main body 154 is “b” as shown in the figure. On the other hand, in FIG. 22B, the vertical lengths of the ridge-side main body 150 and the eaves-side main body 152 are “a”. Since b> a, the vertical length of the short-side main body 154 is longer than the vertical lengths of the ridge-side main body 150 and the eaves-side main body 152. With such a configuration, in the portion where the short side frame 34 is connected to the eaves side frame 24, the hollow portion 156 shown in FIG. 22C is connected to the hatched portion shown in FIG. The Therefore, at least a part of the hollow portion 156 in the short-side body portion 154 is exposed from the opening side of the eaves-side engaged portion 32.

  As a result, the moisture accumulated in the hollow portion 156 flows toward the eaves side frame 24 along the inclination of the short side frame 34 and reaches the eaves side engaged portion 32 of the eaves side main body 152. Furthermore, moisture is discharged from the opening of the eaves-side engaged portion 32 to the outside.

  FIGS. 23A and 23B show the configuration of the solar cell module 10 according to a modification of the second embodiment of the present invention. FIGS. 23A and 23B correspond to a modification in which the shapes of the ridge-side engaged portion 30 and the eaves-side engaged portion 32 in FIG. 22B are changed. The solar cell module 10 shown in FIG. 23A has a ridge-side engaged portion 170, an eaves side, instead of the ridge-side engaged portion 30 and the eaves-side engaged portion 32 in FIG. An engaged portion 172 is included. The eaves side engaged portion 172 is formed in the same manner as the eaves side engaged portion 32. On the other hand, the ridge-side engaged portion 170 extends downward from the inner end of the bottom surface of the ridge-side main body 150 and then bends outward. That is, the ridge-side engaged portion 170 and the eaves-side engaged portion 172 both open toward the outside of the solar cell module 10.

  The solar cell module 10 shown in FIG. 23B has a ridge-side engaged portion 174, an eaves side, instead of the ridge-side engaged portion 30 and the eaves-side engaged portion 32 in FIG. An engaged portion 176 is included. The ridge side engaged portion 174 is formed in the same manner as the ridge side engaged portion 30. On the other hand, the eaves-side engaged portion 176 extends downward from the outer end of the bottom surface of the eaves-side main body 152 and then bends inward. That is, the ridge-side engaged portion 174 and the eaves-side engaged portion 176 both open toward the inside of the solar cell module 10.

  According to the present embodiment, the main body portion is provided so as to protrude inward of the solar cell panel from the portion of the frame into which the solar cell panel is fitted. Can be applied to the main body. Moreover, since it has a gravity center in an inner side direction from the intermediate position which goes to the center from the peripheral part of a solar cell panel among a 1st surface and a 2nd surface, even when it receives a load, it is an inner direction of a solar cell panel Can be applied to the main body. Moreover, since the force toward the inner side of the solar cell panel is applied to the main body, it is possible to apply a force for the frame to bend toward the inner side of the solar cell panel. In addition, since a force to bend the frame toward the inner side of the solar cell panel is applied, it is difficult to drop the solar cell panel from the frame.

  Further, since the opening is formed inside the main body, the weight of the frame can be reduced. Moreover, since the frame is reduced in weight, the solar cell module can be reduced in weight. In addition, since the opening is formed inside the main body, the corner piece pressure can be easily released to the inside. Moreover, since the pressure of a corner piece escapes inside, the pressure added to the outer wall of a main body can be reduced. Moreover, since the pressure applied to the outer wall of the main body is reduced, the occurrence of bulges on the outer wall can be prevented. Further, since the occurrence of bulges on the outer wall is prevented, appearance abnormality can be improved. Moreover, since the 3rd surface which spaces apart and opposes from the back surface of a solar cell panel is extended in the inner side direction of a solar cell panel from a 2nd surface, an excess silicone resin can be stored. Moreover, since excess silicone resin is stored, the application amount of the silicone resin can be increased, and the adhesion area of the back surface of the solar cell panel can be increased.

  Moreover, since the silicone resin is applied across the second surface and the third surface, the amount of the silicone resin that protrudes from the surface of the solar cell panel can be reduced. Further, since the amount of silicone resin that protrudes from the surface of the solar cell panel is reduced, the appearance of the solar cell module can be improved. Further, since the amount of silicone resin that protrudes from the surface of the solar cell panel is reduced, the width of the frame on the surface of the solar cell panel can be reduced. Moreover, since the hollow part in which a water | moisture content tends to accumulate in the short side frame is exposed outside by the eaves side engaged part in the eaves side frame, the water can be discharged. Moreover, since moisture is discharged, freezing of moisture accumulated in the frame can be suppressed. Moreover, since freezing of moisture is suppressed, deformation of the frame is suppressed. Moreover, since it has a structure in which moisture is discharged, drilling can be eliminated. Further, since the drilling process is not required, an increase in the number of manufacturing steps can be suppressed. Further, since the drilling process is not required, an increase in cost can be suppressed.

(Embodiment 3)
Next, a third embodiment will be described. In Embodiment 3, another form of the wedge used when installing the solar cell module shown in Embodiments 1 and 2 will be described. When a wedge is formed using an aluminum member, the spring property of the wedge is reduced. The smaller the spring property of the wedge, the more difficult it is to remove the wedge from the fitting hole. If the removal becomes difficult, the construction becomes difficult and the maintainability becomes low. On the other hand, there is a resin member as a material having a large spring property. However, when rust is formed using the resin member, the weather resistance is lowered. If the weather resistance is low, long-term guarantee becomes difficult. In this embodiment, the wedge is formed of a metal, particularly a metal having a large spring property. An example of a metal is stainless steel. Here, it demonstrates centering on the difference with the wedge demonstrated in Embodiment 1. FIG.

  24A to 24C show the configuration of the wedge 276 according to the third embodiment of the present invention. In particular, FIG. 24A is a perspective view of the wedge 276. FIG. 24B is a front view of the wedge 276 from the eave direction, and FIG. 24C is a top view of the wedge 276.

  For the wedge 276, for example, stainless spring steel (SUS spring steel) is used. Since stainless spring steel has a stronger strength than aluminum, it is possible to reduce the thickness while securing the strength as compared with the case of molding with aluminum. Therefore, the wedge 276 can be molded with a thinner material than the wedge 76, and the spring property is increased. Further, since SUS spring steel can be formed thinner than aluminum, the wedge 276 has a bonnet structure in order to make the entire thickness of the wedge 276 equal to the thickness of the wedge 76 as shown in FIG. The The wedge 276 is not limited to SUS spring steel, and may be formed of copper or iron.

  The first fitting claws 278a and the second fitting claws 278b project inwardly at the lower part of the wedge 276 and at both ends. Further, as shown in FIG. 24B, the outer claw 280 protrudes outward from the upper left portion of the wedge 276. Further, the claw receiving portion 282 is provided outward in the lower right portion of the wedge 276.

  According to this embodiment, since SUS spring steel is used, it can be easily removed by a spring mechanism. Moreover, since removal is easy, workability | operativity can be improved. Moreover, since the removal is easy, the maintainability can be improved. Moreover, since a metal is used, weather resistance can be improved. Moreover, since the weather resistance is improved, a long-term guarantee of the product can be realized.

  The present invention has been described based on the embodiments. This embodiment is an exemplification, and it will be understood by those skilled in the art that various modifications can be made to each component or combination of each processing process, and such modifications are within the scope of the present invention. .
