Description

  The present invention is not only capable of easily attaching a solar cell panel having a frame to the peripheral frame, or a solar cell panel to which a steel material such as an angle material or a channel material is previously attached to the frame on the laying surface, The present invention relates to a mounting member for a solar cell panel used for securely mounting the solar cell panel and a solar cell panel mounting structure using the mounting bracket.

  In recent years, in addition to the diversification of power supply, the use of natural energy has become active due to the growing interest in environmental issues. Among them, the technical improvement and cost reduction of solar cells are progressing, and the installation on the roofs of houses and the roofs and walls of buildings is widespread. In addition, the installation of solar cell panels consisting of solar cell modules on a large-area site has increased expectations for power generation for high-power power supply to supplement hydropower, thermal power, or nuclear power generation. .

  The solar cell panel is required to be firmly fixed after being attached to the attachment surface or the laying surface in consideration of exposure to wind and rain and long-term use. This requirement is particularly strong when installing on large-area sites for high-output power generation, and foundation work for mounting solar cell panels is often performed with solid concrete blocks. On the other hand, it is desirable that the attaching operation is simple, and in some cases, it is preferable that the attaching operation can be easily removed by repair or the like.

  The installation of the solar cell panel is usually performed using a solar cell panel having the following two typical structures. One is a so-called “periphery frame” formed using a metal rim material (hereinafter referred to as a frame) such as an aluminum alloy having excellent light resistance and having a groove-shaped cross-sectional shape that is fitted around the periphery of the solar cell module. A solar cell panel provided with a frame. The other is a structure in which steel materials such as angle materials and channel materials are attached and fixed in advance to a part of the frame around the "solar cell panel having a frame on the peripheral frame". Solar panel ”. If steel materials such as angle materials and channel materials are attached to the solar panel in advance, it is sufficient to attach only angle materials or channel materials from the upper side to the roof, wall, or frame at the work site. It is a structure that is often used because it can be safely and easily performed in a place exposed to the environment or a large site, and workability can be improved. This “solar cell with a steel material attached in advance to the frame” is not limited to the above-mentioned “solar cell having a frame provided on the peripheral frame”, but also directly to the frame of a solar cell module having no metal frame. It also includes the case of installing steel materials such as channel materials.

  Various methods have been proposed as the mounting structure of the “solar cell panel with a frame provided on the peripheral frame”. For example, Patent Document 1 discloses a mounting structure in which fixing seats are provided on edge members on both sides of a peripheral frame (frame) of a solar cell in order to eliminate a frame when the solar cell panel is directly installed on a roof. Has been. Further, Patent Document 2 discloses a solar cell module fixing bracket that enables easy and reliable installation of the solar cell module. The fixing bracket for solar cell module described in Patent Document 2 is a sandwich in which the solar cell module is sandwiched between a flange piece that presses and fixes an end of the solar cell module from the upper surface side and the flange piece from the lower surface side. There is a dressing piece and a fixed piece to be fixed to the gantry, and a biting claw of the sandwiching piece is provided with a biting claw whose tip is formed in a pointed shape.

  In addition to the structures disclosed in Patent Documents 1 and 2, a solar battery panel using a mounting bracket for attaching the solar battery panel to a laying surface made of a concrete block as in the conventional structure shown in FIG. May be installed. In the example of the mounting bracket shown in the portion surrounded by the alternate long and short dash line in FIG. 19, in order to press the end of the solar cell panel from the upper surface side (light receiving surface), it is crank-shaped with the same thickness as the solar cell panel. It has a molded metal plate and a metal plate for sandwiching and fixing the concrete block, and the solar cell panel is fixed by overlapping both metal plates and fastening them with bolts or the like.

  On the other hand, with regard to the mounting structure of “solar cell panel in which steel material is previously mounted on the frame”, for example, Patent Document 3 proposes a structure in which the outer periphery of the solar cell panel is fixed at the tip of a metal plate bent in a crank shape. ing. Further, in Patent Document 4, in order to improve the drawbacks of the mounting structure disclosed in Patent Document 3, for the purpose of reducing the rise of the crank-shaped metal plate that is deformed, the gantry side and the crank-shaped metal plate are A fixing structure is disclosed in which a spacer is interposed between the other side or a gap forming means between back plates of a crank-shaped metal plate is sandwiched.

  However, since the mounting structure or the fixture described in Patent Documents 1 and 2 is a structure in which a solar panel or module is simply sandwiched between upper and lower plates, the solar panel or module is required to be firmly fixed. It was not enough to respond to. Among them, the fixing bracket described in Patent Document 2 can easily perform the installation work of the solar cell module, and further has a biting claw in which the tip of the bent portion end of the sandwiching piece is formed in a pointed shape. Although it has the effect of regulating the displacement of the solar cell module because it is provided, it is difficult to say that it can sufficiently withstand shaking such as wind and rain and earthquakes.

  In addition, the mounting bracket shown in FIG. 19 is one that clamps the solar cell panel using two metal plates and then fixes it with a tightening jig such as a bolt. The mounting operation of the solar cell panel is easy. Conceivable. However, since it is a structure in which the solar panel is simply sandwiched between the upper and lower plates, like the mounting brackets described in Patent Documents 1 and 2, the solar cell panel can not be sufficiently satisfied with the demand to be firmly fixed. Absent. Therefore, there is a problem that it is still not enough to withstand long-term use in a harsh environment.

  On the other hand, since the mounting structure described in Patent Document 3 is a structure in which the outer periphery of the solar cell panel is simply fixed at the tip of a metal plate bent in a crank shape, the solar cell panel after mounting is warped by a strong wind. In the worst case, the solar cell panel may come off. The fixing structure described in Patent Document 4 proposed to improve this problem requires not only a work for interposing a spacer or a space forming means, but the mounting work is not only very complicated. It becomes a work that requires skill. Moreover, since it is a function which presses and fixes a solar cell panel from the upper and lower sides, the problem that a solar cell panel shifted or dropped out with the big force to a horizontal direction was not able to be wiped away completely.

  The present invention has been made in view of the above-described conventional problems, and in the conventional solar cell panel mounting structure, it has been impossible to ensure a reliable and strong mounting property in a severe environment. By optimizing the structure and structure of the mounting brackets for technical problems, not only can the solar cell panel be easily mounted on the laying surface, but also the mounting can be performed reliably and firmly. An object is to provide a solar cell mounting bracket and a solar cell panel mounting structure using the mounting bracket.

  In the present invention, the mounting bracket is constituted by two metal plates disposed on the side surface (side surface and upper side if necessary) and the lower side of the solar cell panel so that the solar cell panel can be easily mounted. In addition, to easily adjust the mounting position of the solar cell panel, and to securely attach and fix the solar cell panel after installation, the end of the metal plate for supporting the solar cell panel arranged on the lower side is characterized by It has been found that the above-mentioned problems can be solved by providing an engaging protrusion having a certain structure, and the present invention has been achieved.

  The solar cell panel mounting bracket according to the present invention is a first metal for pressing not only the side surface side of the solar cell panel but also the side surface side as necessary, so that the solar cell panel can be easily mounted. The first feature is that the metal plate is composed of two metal plates including a plate and a second metal plate for supporting the lower side of the solar cell panel. In order to allow a metal rod such as a bolt used as a tightening jig to pass through at least the first metal plate of the two metal plates on the surface opposite to the side in contact with the solar panel. Holes are formed. In the present invention, the hole for penetrating a metal rod such as a bolt used as a tightening jig is provided not only on the first metal plate but also on the side contacting the solar panel of the second metal plate. It is practical to form it also on the opposite surface. By forming the hole in the second metal plate in advance, the work for forming the hole in the second metal plate is not required when the solar cell panel is attached. However, when the first metal plate is abutted against the second metal plate while pressing the side surface side of the solar cell panel and, if necessary, the side surface side and the upper side, the positions of the holes are adjusted to the positions of the two metals. It may be difficult to match between the plates, and it may be better to form the holes in the second metal plate later by a matching operation. In that case, you may form the said hole in the same position by the drill etc. from the said hole previously formed in the said 1st metal plate in the said 2nd metal plate in which the said hole is not formed.

  After the solar cell panel is mounted on the second metal plate and pressed by the first metal plate in a state where the mounting position of the solar cell panel is adjusted to a desired position, a bolt, a nut, and The two metal plates are fastened and fixed using a fastening jig such as a washer. The solar cell panel can be directly attached to the laying base by adopting a structure in which bolts and the like reach the laying base such as a concrete block or a metal plate block in the fastening jig.

  When the mounting position of the solar cell panel is adjusted to a desired position by the first metal plate, the solar cell panel is arranged so that the position of the solar cell panel mounted on the second metal plate does not easily move. It is necessary to support firmly. Therefore, the second metal plate of the mounting bracket according to the present invention has the frame or the angle material or the channel material steel material located at the bottom of the solar cell panel at the end on the side in contact with the solar power panel. It is a second feature of the present invention that an engagement protrusion having a folded structure for engaging with and fixing the solar cell panel is provided. In the mounting bracket of the present invention, the reason why the folding structure is provided as the engaging projection is as follows.

  In the “solar cell in which a frame is provided on the peripheral frame”, the engagement protrusion having the folded structure is engaged with the end of the frame located at the bottom of the solar cell panel. The minute position fluctuation of the end portion of the frame, which is likely to occur in the installation process of one metal plate and the clamping process of both metal plates, can be supplemented by a change in the folding angle of the engagement protrusion. By this function, an effect that the frame can be firmly supported is obtained. Further, in the “solar cell panel in which a steel material is previously attached to the frame”, when the engagement protrusion having the folded structure is engaged with the end of the steel material located at the bottom of the solar cell panel, Since the end of the steel material is shaped so as to be joined to the recessed portion of the folded portion, the steel material can be firmly held. In addition, since the folding structure can compensate for the minute position fluctuation of the end portion of the steel material that occurs when the first metal plate is attached by the change in the folding angle of the engagement protrusion, as a result In addition, the solar cell panel can be securely and firmly fixed.

  In the mounting bracket of the present invention, as the first metal plate, since it is necessary to press at least only the side surface side of the solar cell panel, the first metal plate has at least one bent portion, and the side surface of the solar cell panel. A frame formed in an L shape so as to come into contact with the frame or the steel material of the angle material or the channel material is used. Furthermore, since the solar cell panel can be attached more reliably and firmly by pressing not only the side surface side but also the upper side of the solar cell panel, the first and second bent portions are provided. And having a structure formed by bending in a crank shape so as to contact the frame or the steel material respectively positioned on the upper surface corresponding to the light receiving surface side of the solar cell panel and the side surface of the solar cell panel. .

  Next, embodiments of the mounting bracket of the present invention and a solar cell panel mounting structure using the mounting bracket will be described with reference to the drawings, but the present invention is not limited to the following embodiments.

<First Embodiment>
FIG. 1 is a diagram showing an example of a mounting bracket of the present invention in which a first metal plate is bent in an L shape and a solar cell panel mounting structure using the mounting bracket. FIG. 1A is a perspective view of a solar cell panel mounting structure, and shows a state in which one corner of the solar cell panel is mounted by the mounting bracket of the present invention as an example of solar cell panel mounting. . Moreover, (b), (c) and (d) of FIG. 1 is a figure when the AA position shown to (a) of FIG. 1 is seen from a cross section, and it is a solar cell panel using the mounting bracket of this invention. Each process when attaching and fixing is shown. 1C corresponds to the cross-sectional view taken along the line AA shown in FIG.

  As shown in FIG. 1, the solar cell panel 1 has a structure in which a frame is provided on a peripheral frame. A mounting bracket 10 used when the solar cell panel 1 is attached includes a first metal plate 11 and a second metal plate 12. Here, the first metal plate 11 is formed to be bent in an L shape and have one bent portion 13. Further, the second metal plate 12 is folded at the end on the side in contact with the solar panel 1 to engage with the frame 2 located at the bottom of the solar panel 1 and fix the solar panel 1. An engaging projection 14 having a structure is provided. Holes 15 and 16 are formed in both metal plates 11 and 12 on the surface opposite to the side in contact with the solar cell panel. The holes 15 and 16 are bolts used as a tightening jig for stacking and tightening the two metal plates 11 and 12 after the solar cell panel is mounted in contact with the two metal plates 11 and 12. It is provided for penetrating a metal rod such as. FIG. 1D shows a configuration example including a bolt 4 and two nuts 5 as the tightening jig 3, but other parts such as washers may be used as necessary. .

  As shown in FIG. 1B, after the solar cell panel 1 is mounted on the second metal plate 12, the first metal plate 11 is pressed against the side surface of the solar cell panel 1. Then, the first metal plate 11 is brought into contact with the side surface of the solar cell panel 1 so that the holes 15 and 16 provided in the two metal plates 11 and 12 are overlapped and overlap each other ((c) in FIG. 1). . Here, the hole 16 provided in the second metal plate 12 may be formed by using a drill or the like from the upper part of the hole 15 after the two metal plates 11 and 12 are brought into contact with each other. Next, the bolts 4 used as the fastening jigs 3 are passed through the holes 15 and 16 provided in the two metal plates 11 and 12 to the laying base 6 and then fastened and fixed with the nut 5 (see FIG. 1). (D)). Here, the laying base 6 is fixed to the solar cell by tightening both metal plates from the upper side of the first metal plate 11 and the lower side of the second metal plate 12 using two nuts 5. The installation position of the panel 1 can be freely adjusted in the vertical direction.

  The function and action of the engaging protrusion 14 having the folded structure, which is cited as the second characteristic point of the mounting bracket of the present invention, will be described with reference to FIGS. On the right side of FIG. 1 (c), in the engagement protrusion 14 engaged with the frame 2 located at the bottom of the solar cell panel 1, those two typical engagement states are surrounded by a portion surrounded by a one-dot chain line. An enlarged view is shown. In the enlarged view (I), when the first metal plate 11 is brought into contact with the side surface of the solar cell panel 1, the frame 2 is flat when the tip of the folded portion of the engagement protrusion 14 is slightly warped upward. It is a state engaged with the end portion. Enlarged view (II) shows a state in which the end of the folded portion of the engaging projection 14 is engaged with the flat end of the frame 2 while the tip is recessed downward. That is, when the first metal plate 11 is brought into contact with the side surface of the solar cell panel 1, an enlarged view (I) and an enlarged view (II) according to the movement of the frame 2 where the tip of the folded portion is located at the bottom. By deforming into one of the states shown in FIG. 1, the solar cell panel 1 can be firmly pressed down when tightened using the tightening jig 3 in the step shown in FIG.

  As described above, the folding structure of the engagement protrusion 14 compensates for the minute position fluctuation of the end of the frame, which is likely to occur in the steps (b) and (c) of FIG. 1, by the change of the folding angle. It has the function and action of being able to. Furthermore, even if this folded structure is an attachment structure using the first metal plate 11 bent in an L shape, the solar cell panel 1 has a function of firmly pressing and fixing the solar cell panel 1 from both side surfaces thereof. The battery panel 1 can be securely attached. If the engagement protrusion 14 is a simple protrusion having no folded structure, the functions shown in the enlarged view (I) and the enlarged view (II) of FIG. If the solar cell panel 1 is forcibly attached by pressing the first metal plate 11, the solar cell panel 1 may jump out to the top, or in the worst case, the bottom of the solar cell panel 1 may be damaged. .

  Therefore, the attachment and fixing of the solar cell panel 1 by the first metal plate 11 bent in an L shape has an advantage that the operation is easy by using a metal plate having a simple shape of L shape. However, at the same time, by providing the engaging protrusion having the folded structure at the end, it is possible to carry out in a reliable and relatively solid state.

A modification of the sixth embodiment is shown in FIG. FIGS. 8A, 8B, and 8C are a perspective view, a front view, and a plan view, respectively, of the mounting bracket of the present embodiment. 8D and 8E are a plan view and a front view, respectively, when the solar cell panel mounting structure using the mounting bracket of this embodiment is viewed from above and from the front. As the solar cell panel, an example of “a solar cell panel in which a steel material is previously attached to a frame” is shown. Moreover, as a solar cell panel mounting structure, as in the sixth embodiment, only the portion where four solar cell panels are mounted using one mounting bracket is extracted and simplified. Show.

  As shown in FIGS. 8A, 8 </ b> B, and 8 </ b> C, the mounting bracket 70 has two sets of first and second bent portions 73 a and 73 b, and receives light from the solar cell panel 7.

  As described above, the four solar cell panels 7 can be attached and fixed together, but when the number of solar cell panels 7 to be attached increases, these steps are repeated. The mounting bracket of the present embodiment can achieve an effect equal to or greater than that of the sixth embodiment. In particular, since the first metal plate 71 has a structure for pressing not only the side surface side of the solar cell panel 7 but also the upper side, the solar cell panel 7 can be attached more reliably and firmly. Therefore, regarding the mounting and fixing of the solar cell panel, the reliability and durability can be greatly improved as compared with the sixth embodiment. Further, the folding structure of the engaging protrusion 74 is tapered as shown in FIG. 8C, so that workability and mounting strength are improved when mounting four solar cell panels at once.

On the other hand, the second metal plate 82 has the same structure as 72 shown in FIG. 8, and four engaging projections 84 each having a folded structure are provided separately at the four corner ends.

  The structure of the mounting bracket 80 shown in FIG. 9 is that a first metal plate 81 and a second metal plate 82 are fastened to a fastening jig (not shown) through holes 85 and 86 provided in the two metal plates, respectively. When tightening with a tool, not only is the work space a little wider, it is easier to work, but the number of holes 85 and 86 for tightening can be increased to make mounting and fixing more robust. can get. 9A shows a mounting bracket in which concave grooves 87 are provided between holes provided in two rows in the first metal plate 81. The mounting bracket of this embodiment is shown in FIG. As shown in FIG. 9D, a structure in which two rows of holes are formed on a flat surface without providing the grooves 87 may be used.

  Next, FIG. 10 shows an example of a mounting bracket whose structure has been optimized based on the mounting bracket shown in FIG. 8 in order to more easily perform the solar cell panel mounting operation. In FIG. 10, (a) is a front view of the mounting bracket, and (b), (c) and (d) are views showing a part of the solar cell panel mounting step.

  As shown in FIG. 10 (a), the mounting bracket 90 has a solar cell panel in which the straight portion of the second metal plate 92 that abuts the angle 8 located at the bottom of the solar cell panel 7 on the opposite side to the light receiving surface. 7 is longer than the portion of the first metal plate 91 that is in contact with the angle located on the upper surface corresponding to the light receiving surface side of 7.

  In the attachment process shown in FIGS. 10B to 10D, first, the tip end portion of the angle 8 located at the bottom portion of the solar cell panel 7 has a folded structure in which the end portion of the second metal plate 92 is provided. After being inserted into the recessed portion of the folded portion of the engaging protrusion 94, the solar panel 7 is moved so as to be inserted in the lower direction in order to bring the side surface of the solar cell panel 7 into contact with the first metal plate 91. . ((B) of FIG. 10). At this time, the mounting bracket 90 has two bolts 4 used as the fastening jig 3 passing through the holes 95 and 96 provided in the two metal plates 91 and 92 to the laying base 6 made of concrete or the like. The nut 5 is fixed slightly loosely (FIG. 10 (b)). Then, the upper surface, the side surface, and the lower surface of the solar cell panel 7 are brought into contact with the first metal plate 91 and the second metal plate 92 ((c) of FIG. 10). Next, the bolt 4 and the nut 5 are further tightened to securely fix the solar cell panel 7 ((d) in FIG. 10).

  In the mounting bracket 90 shown in FIG. 10, the straight portion of the second metal plate 92 is longer than the portion of the first metal plate 91 in contact with the steel material located on the upper surface corresponding to the light receiving surface side of the solar cell panel 7. Therefore, the solar cell panel 7 can be attached simply by being inserted into the attachment fitting 90, and the attachment operation is facilitated. Furthermore, since the solar cell panel 7 can be reliably aligned by the first metal plate 91 and the second metal plate 92, the solar cell panel 7 can be firmly fixed by the tightening jig 3. In particular, when four solar cell panels are attached in a lump, it is a preferable structure because both the speed of work and the certainty of attachment can be achieved.

<Eighth Embodiment>
When four solar cell panels are mounted and fixed using one mounting bracket, the mounting structure shown in FIG. 11 is used in addition to the seventh embodiment in which four solar cell panels are mounted simultaneously. Can be adopted. FIG. 11 is a diagram showing a solar cell panel mounting bracket and a solar cell panel mounting structure using the mounting bracket described in the present embodiment.

  In FIG. 11 (a), using the mounting bracket 100, four solar battery panels are attached together, and the desired number of solar battery panels 7a and 7b are installed in the first and second rows, respectively. The perspective view after attaching and fixing is shown. The mounting bracket 100 can be obtained by optimizing the structure based on the mounting bracket 90 shown in FIG. 10 so as to be suitable for the application of the present embodiment. A solar cell 7b indicated by a dotted line in FIG. 11A is a plurality of solar cell panels constituting the second row that is attached and fixed after the solar cell panel 7a is attached. The solar cell panels 7a and 7b are attached and fixed in accordance with the steps shown in FIGS. Here, (b)-(d) of FIG. 11 has shown a part of attachment process when it sees from the direction of E shown to (a) of FIG.

  As shown in FIG. 11 (b), the mounting bracket 100 includes a second metal plate 102 on one side (a side in the drawing) and the other side (b side in the drawing) in the central portion of the metal plate. It has a sliding function that can be expanded and contracted in the same direction as the longitudinal direction of the first metal plate having a portion formed by bending into the L shape or the crank shape so that it can be separated in the vertical direction. . Here, the “longitudinal direction of the first metal plate having a portion formed by bending the L shape or the crank shape” refers to the direction from the a side to the b side shown in FIG. means. In addition, the second metal plate 102 is provided with two through holes 106a and 106b in the upper and lower metal plate portions separated in a sliding manner. The through holes 106a and 106b are formed at positions that coincide with the through holes 105 when the first metal plate 101 is overlapped after the solar cell panels 7a and 7b are attached. As the slide type employed in the second metal plate 102, a guide for movement may be provided on each of the upper and lower metal plate portions so that the upper and lower metal plate portions separated by the slide method are not easily separated during the mounting operation.

  In the step shown in FIG. 11B, the solar cell panel 7a constituting the first row and the solar cell panel 7b constituting the second row are moved to the a side and b side in the drawing, respectively, and are positioned at the bottom. Steel materials 8a and 8b to be inserted are inserted into the recessed portions of the folded-back portions of the engaging projections 104a and 104b provided at both end portions of the second metal plate, respectively. In this way, the solar cells 7 a and 7 b are attached to the second metal plate 102. Here, the slide provided on the second metal plate 102 is set to a length that can secure a wide space so that the work is facilitated when the solar cell panels 7a and 7b are moved. Further, the length of the first metal plate 101 in contact with the second metal plate 102 is determined according to the length of the slide. As described above, by adopting the slide-type configuration for the second metal plate 102, the work when the solar cell panels 7a and 7b are attached to the second metal plate 102 becomes very easy.

  Next, as shown in FIG. 11 (c), the first metal plate 101 is attached so as to simultaneously press the steel materials positioned on the upper and side surfaces of the solar cells 7a and 7b, respectively. At this time, the first metal plate 101 is brought into contact with the upper and side surfaces of the solar cell panels 7a and 7b so that the holes 105 and the holes 106a and 106b provided in the second metal plate 102 coincide with each other. . After that, as shown in FIG. 11 (d), the bolt 4 used as the fastening jig 3 is passed through the laying base 6 made of concrete or the like, and then fastened and fixed using the two nuts 5.

  In FIG. 11, as an example of mounting and fixing the solar cell panel, the case of installing in the first row and the second row has been described, but in the present embodiment, even in the case of installation by a multi-stage arrangement in the third row and thereafter. By performing the same process, it is possible to efficiently attach and fix the solar cell panel. Further, if the mounting bracket 100 shown in FIG. 11 is used, the steps (b) to (d) shown in FIG. The removal work can be facilitated by carrying out the reverse of d) → (b). In particular, when removing the solar cell panels installed in a multi-stage arrangement from the third row onward, the space for moving the solar cell panels is wide, so that not only can the work be made more efficient, The degree of freedom of the process increases. If repair or the like of the solar cell panel is necessary, it is possible to respond quickly by simply performing the repair work, and the effect that the maintainability of the solar cell panel is excellent can be obtained.

  In this embodiment, in addition to the mounting bracket for the solar cell panel shown in FIG. 11, by using a mounting bracket having another structure, the solar cell panel shown in FIG. The same effect can be achieved. FIG. 12 shows a modification of the mounting bracket and mounting structure of the solar cell panel shown in FIG.

  As shown to (a) of FIG. 12, what provided the through-opening 117 in the inside including the line symmetrical center part of the metal plate 112 is used as the 2nd metal plate 112 of the attachment metal fitting 110. FIG. The through-opening 117 is formed in the second metal plate 112 so as to have a larger area than a hole for allowing the bolt 4 used as the fastening jig 3 to pass therethrough, and to be shaped so as to tie the hole. . In addition, the metal plate component 118 surrounded by one-dot chain line in the right view of FIG. 12A is in the through-opening 117 before or after the solar cell panels 7a and 7b are mounted on the second metal plate component 112. And has the same shape as the through-opening portion 117 and has the same area or a slightly smaller area. The metal plate component 118 is formed to have the same thickness as the second metal plate 112 or slightly thinner than that, and a hole 116 for penetrating the bolt 4 used as the fastening jig 3 is formed in the center portion. ing. The shape of the metal plate component 118 is not limited to the circular shape shown in FIG. 12A, and may be an ellipse, a rectangle, a rhombus, or a polygon. It is preferable to form in the shape substantially the same as the through-opening part 117 provided in the inside containing. When the shape and area of the metal plate part 112 are significantly different from those of the through opening 117, problems such as poor insertability and ease of rattling after insertion occur.

  In the step shown in FIG. 12 (a), the solar cell panel 7a constituting the first row and the solar cell panel 7b constituting the second row are made of steel materials 8a and 8b located at the bottom of the second metal plate. It is moved to the a side and the b side in the figure so as to be inserted into the recesses of the folded portions of the engaging projections 114a and 114b provided at both end portions, respectively. In this way, the solar cells 7 a and 7 b are attached to the second metal plate 112. Thereafter, the metal plate component 118 is inserted into the through opening 117 of the second metal plate 112. Here, the through opening 117 and the metal plate component 118 are formed with an area or length that can secure a wide space so that the work is facilitated when the solar cell panels 7a and 7b are moved. Further, the length of the straight portion of the first metal plate 111 that comes into contact with the second metal plate 112 is determined according to the diameter or length of the through opening 117. In this way, the work for mounting the solar cell panels 7a and 7b to the second metal plate 112 by inserting the metal plate component 118 having substantially the same shape and area into the inside of the second metal plate 112. Becomes easier.

  Next, as shown in FIG. 12B, the first metal plate 111 is attached so as to simultaneously press the steel materials positioned on the upper and side surfaces of the solar cells 7a and 7b, respectively. At this time, the first metal plate 111 is brought into contact with the upper and side surfaces of the solar cell panels 7a and 7b so that the hole 115 and the hole 116 provided in the metal plate component 118 are aligned and overlapped. After that, as shown in FIG. 12C, the bolt 4 used as the fastening jig 3 is passed through the laying base 6 made of concrete or the like, and then fastened and fixed using the two nuts 5.

  In the present embodiment, instead of using the metal plate component 118 used in the steps shown in FIGS. 12A to 12C, as shown in FIG. A protruding portion 119 having a step that is the same as or slightly smaller than the through-opening portion 117 provided in the second metal plate 112 and has a thickness substantially the same as that of the second metal plate 112 may be provided in the lower portion. good. In addition, a hole corresponding to the hole 116 through which the bolt 4 used as the fastening jig 3 passes is communicated with a portion corresponding to the hole 115 provided in the first metal body 111. It is formed in a shape. As described above, the protruding portion 119 can be formed to have the same function and action as the metal plate component 118.

  By using the mounting bracket 110 shown in FIG. 12, a wide space for moving the solar cell panel can be secured not only when installing the solar cell panel by multi-stage arrangement but also when removing the solar cell panel. . Therefore, as in the case where the mounting bracket 100 shown in FIG. 11 is used, not only can the efficiency of the work be improved, but also the effect that the degree of freedom of the work process is increased can be obtained.

  11 and 12, this embodiment uses a mounting bracket made of a first metal plate that has two bent portions and is bent into a crank shape. An example of a mounting structure for mounting and fixing a “battery panel” is shown, but in addition, mounting having two sets of L-shaped portions having one bent portion as the first metal plate You may use metal fittings. Moreover, also about a solar cell panel, the attachment and fixation of "the solar cell panel by which the frame was provided in the surrounding frame" can be performed using the attachment metal fitting of this embodiment.

<Ninth Embodiment>
As described above, the first feature of the solar cell panel mounting bracket according to the present invention is that it is composed of the first metal plate and the second metal plate in order to facilitate the mounting operation. In the present invention, it is not always necessary to use the first metal plate and the second metal plate separately, by pressing the solar cell panel mounted on the second metal plate with the first metal plate, If the solar cell panel has a function capable of coming into contact with both metal bodies, the first metal plate and the second metal plate are opposite ends on the side in contact with the solar panel. It is possible to use one integrated by joining or press molding.

  FIG. 13 shows a solar battery panel mounting bracket 120 in which a first metal plate and a second metal plate are integrated. 12A and 12B are a perspective view of a mounting bracket 120 including a portion 121 corresponding to a first metal plate formed by bending in an L shape so as to have one bent portion 123, respectively. FIG. 5 is a cross-sectional view of the FF position, in which a first metal plate 21 and a second metal plate 22 provided in the mounting bracket 20 illustrated in FIG. 2 are integrated. 13 (c) and 13 (d) show a mounting bracket including a portion 131 corresponding to a first metal plate formed by bending in a crank shape so as to have two bent portions 133a and 133b, respectively. FIG. 13 is a perspective view of FIG. 130 and a cross-sectional view at a position G-G, in which a first metal plate 41 and a second metal plate 42 provided in the mounting bracket 40 shown in FIG. 5 are integrated.

  The fittings 120 and 130 in which the first metal plate and the second metal plate shown in FIG. 13 are integrated can be obtained by bending one metal plate using press molding. A hole for penetrating a metal rod such as a bolt, which is a tightening jig, can be provided at a location corresponding to a hole provided in the first metal plate and the second metal plate before being bent by press molding. Further, the holes may be provided after being bent by press molding. For example, in a state where a plate corresponding to the first metal plate is pressed against a plate corresponding to the second metal plate, a hole or the like is collectively used. Can be formed.

  By integrating the first metal plate and the second metal plate, the number of parts can be easily managed in the manufacture of the mounting bracket, and mass production by a batch line is possible, thereby reducing the manufacturing cost. Can do. In addition, this mounting bracket does not need to be handled by a combination of two metal plates, the first and second metal plates, and the member management is facilitated, and it is necessary to perform the work of aligning the respective metal plates when mounting the solar cell panel. Therefore, the working efficiency can be improved.

  In the present embodiment, the portions 121 and 131 corresponding to the first metal plate play an important role for pressing and holding and fixing the solar cell panel 7. Therefore, the metal plates of the portions 121 and 131 corresponding to the first metal plate preferably have a function of elastic deformation so that the solar cell panel can be held and fixed only by elastic deformation. As one of the methods, the thickness (t) of the metal plates of the portions 121 and 131 corresponding to the first metal plate is preferably set to any value in the range of 0.5 to 0.25 mm. When the thickness is less than 0.5 mm, the effect of pressing the solar cell panel cannot be obtained because the metal plate is too thin. On the other hand, if the thickness exceeds 0.25 mm, the metal plate is too thick and elastic deformation does not occur. On the other hand, the portion corresponding to the second metal plate is used for mounting and supporting the solar cell panel, and if this function is satisfied, it is not necessary to define the thickness.

  As an integrated mounting bracket used in the present embodiment, a first metal plate and a second metal plate other than one metal plate bent using press molding as shown in FIG. What joined each terminal part, and the thing integrated and shape | molded by superimposing can be used. FIG. 14 shows an example of a mounting bracket made of a crank-shaped first metal plate and a flat plate-shaped second metal plate, in which respective end portions are overlapped and integrated by molding.

  Unlike the mounting brackets 120 and 130 illustrated in FIG. 13, the mounting bracket 140 illustrated in FIG. 14 cannot be expected to have the effect of elastic deformation caused by the metal plate corresponding to the first metal plate. Therefore, before the solar cell panel 7 is attached, the portion 141 corresponding to the first metal plate is opened at a certain angle with respect to the portion 142 corresponding to the second metal plate. At the same time, it is necessary for both to be in full contact with each other during the pressing operation. Therefore, as shown in FIG. 14, when the metal plates are fixed between the portion 141 corresponding to the first metal plate and the portion 142 corresponding to the second metal plate, they overlap each other. It is preferable to provide any one of an elastic spring, an elastic body, and a magnet.

  FIG. 14A is a cross-sectional view showing an example in which an elastic spring 147 is provided between a portion 141 corresponding to the first metal plate and a portion corresponding to the second metal plate 142. Reference numeral 147 denotes a central portion of the portions 141 and 142 corresponding to both metal plates, and is installed at a location close to the mounting position of the solar cell panel 7. Before mounting the solar cell panel, the elastic spring 147 opens the portion 141 corresponding to the first metal plate at a predetermined angle from the portion 142 corresponding to the second metal plate. Sometimes, the solar cell panel 7 can be fixed by tightening with a force larger than the repulsive force of the elastic spring using a tightening jig. Here, the repulsive force of the elastic spring 147 is determined by the tightening force, but it is preferable to use an elastic spring that does not have a large repulsive force from the viewpoint of workability, mounting and fixing reliability, and durability.

  FIG. 14B is a diagram illustrating an example in which an elastic body 148 is provided between a portion 141 corresponding to the first metal plate and a portion corresponding to the second metal plate 142. Examples of the elastic body 148 include rubber, flexible resin, an aggregate of metal fibers, or a flexible metal. As shown in FIG. 14B, before the solar cell panel 7 is attached, the portion 141 corresponding to the first metal plate corresponds to the portion 142 corresponding to the second metal plate due to the presence of the protrusions of the elastic body 148. The parts corresponding to both metal plates can be easily opened. When the solar cell panel 7 is attached, the solar cell panel 7 can be fixed by tightening with a force larger than the repulsive force of the elastic body using a tightening jig.

  FIG. 14C is a diagram showing an example in which a magnet 149 is provided between a portion 141 corresponding to one metal plate and a portion corresponding to the second metal plate 142. In the case of the magnet 149, unlike the elastic spring 147 and the elastic body 148, the effect of making the portion 141 corresponding to the first metal plate open with respect to the portion 142 corresponding to the second metal plate is expected. Can not. However, when the portions 141 and 142 corresponding to the two metals are brought into close contact with each other during the pressing operation, it is easy to align the portions. Further, not only the degree of adhesion of the two parts is increased by the magnet 149, but also the effect of preventing the positional deviation between the two parts at the time of the tightening work by the tightening jig is obtained.

  The installation location of the elastic spring 147, the elastic body 148 or the magnet 149 is not limited to the center portion of the portions 141 and 142 corresponding to both metal plates as shown in FIG. This can be installed. When the elastic spring 147, the elastic body 148, or the magnet 149 is installed in the portions 141 and 142 corresponding to both metal plates, a part of the inside of the metal plate is cut through, and an adhesive, an adhesive, A method such as adhesion, close contact, embedding or joining is used by fastening or the like. Further, the elastic spring 147 or the elastic body 148 may be provided at different positions in combination with the magnet 149.

  In addition, in this invention, it is not limited to the structure of FIG. 14 which integrated both the metal plates, but with respect to the fixture which both metal plates as shown in FIGS. Also, any one of the elastic spring, the elastic body, and the magnet can be provided.

FIGS. 16B, 16C, and 16D are views seen from a cross-section at the mounting II position shown in FIG. 16A, and a solar cell using the mounting bracket 160 of the present invention. Each process when attaching and fixing the panel 7 is shown, respectively. Among them, FIG. 16C corresponds to a cross-sectional view taken along the line I-I shown in FIG.

  As shown in FIG. 16, the mounting bracket of the present embodiment has basically the same configuration as that shown in FIG. 15 except for the following points. That is, the second metal plate 162 not only has the extended portion 167b provided in the parallel direction with the steel material positioned on the side surface of the solar cell panel 7, but also the first metal plate 161 is provided in the same parallel direction. A portion 167a is provided, and the extended portion 167a is provided with a hole 168a through which a fastening jig (bolt) used when being fixed to the laying base is passed. Further, the holes 165 and 166 provided in the first metal plate 161 and the second metal plate 162 in order to allow the hole tightening jig (bolt) to pass therethrough are the first metal plate 161 and the second metal body, respectively. From the lower surface of 162 to the holes 168a and 168b formed in the extending portions 167a and 167b provided in the direction parallel to the steel material positioned on the side surface of the solar cell panel 7, respectively, it is continuously formed via the connecting passage 169.

  In the attachment of the solar cell panel 7, the steps (b) to (d) in FIG. 16 are basically the same as the process flows (b) to (d) shown in FIG. The difference is that in the steps of (b) and (c) of FIG. 16, when the first metal plate 161 is brought into contact with the second metal body 162, the direction parallel to the steel material positioned on the side surface of the solar cell panel 7.

In addition, the reliability and durability of the mounting structure can be greatly improved.

<Eleventh embodiment>
The mounting structure of the solar cell panel according to the present invention is basically configured using the mounting bracket of the present invention, but only the solar cell panel is obtained by integrating two or more of the solar cell panels first. The two or more integrated solar cell panels can be attached and fixed to the laying base. That is, it is possible to construct a solar cell panel mounting structure in which both the mounting structure for mounting and fixing only the solar cell panel to each other and the mounting structure for mounting and fixing the solar cell panel to the laying base are mixed. In that case, at least the mounting bracket of the present invention is used as a mounting bracket used for mounting and fixing only two or more solar battery panels to each other, and the mounting bracket used when mounting and fixing to a laying base, The mounting bracket of the present invention or another conventional mounting bracket different from the mounting bracket of the present invention may be used.

  FIG. 17 shows an example of a solar cell panel mounting structure in which a mounting structure for mounting and fixing only the solar cell panels to each other and an mounting structure for mounting and fixing the solar cell panels to the laying base are mixed. FIG. 17 is a plan view of the solar cell panel mounting structure according to the present embodiment as viewed from above. The two solar cells 7 are integrated at four locations corresponding to the locations indicated by J in FIG. 17 by, for example, the mounting bracket 50 of the present invention shown in FIG. The attachment structure at the position indicated by J has a structure as shown in the lower right perspective view surrounded by the alternate long and short dash line.
