Description

  The present invention relates to a structure installation stand for installing a structure such as a solar cell module, a construction method thereof, and a solar cell system.

  This kind of gantry is required not only to support the load of the structure but also to withstand the wind pressure received on the structure, and therefore requires high strength. In particular, when the solar cell module is supported, the solar cell module is flat and inclined, so that a large wind pressure is easily applied to the solar cell module, and sufficient attention is paid to the strength of the gantry. Yes.

  For example, in patent document 1, the support rail which combined the some cylindrical body is fixed, and the edge part of the solar cell module is supported by this support rail. Since the cylindrical body itself has a large section modulus, the strength of the support rail is increased by combining a plurality of cylindrical bodies.

  In Patent Document 2, a plurality of frames having a hat-shaped cross-sectional shape are juxtaposed, and a solar cell module is fixedly supported on these frames. The hat-shaped frame has a large section modulus and high frame strength.

JP 2001-164713 A Japanese Patent Laid-Open No. 9-235844

  Here, in patent documents 1 and 2, since the installation of the solar cell module in a house or the like is a premise, the installation area of the solar cell module is limited, and the support rail and the frame are about several meters at the longest. It is believed that there is.

  However, since a large number of solar cell modules are installed side by side in a large-scale power plant or the like, if the support rails of Patent Document 1 and the frame of Patent Document 2 are applied, these need to be extended.

  In Patent Document 1, a cylindrical portion is provided at one end portion of two support rails, and a rod-like portion is provided at the other end portion, and the cylindrical portion and the rod-like portion of these end portions are fitted to each other. Two support rails are connected, which makes it possible to extend the support rails. However, when these cylindrical portions and rod-shaped portions are provided, the shape of the support rail becomes complicated and the number of parts increases. Moreover, in order to fit the cylindrical part and bar-shaped part of two support rails, it is necessary to support these support rails linearly, and the operation | work is not easy. For this reason, if such a support rail is applied to a large-scale power plant or the like, the cost becomes very high and the construction work becomes difficult.

  Moreover, in patent document 2, there is no description about the extension of a flame | frame, and application of the flame | frame to a large-scale power plant etc. is not considered.

  Therefore, the present invention has been made in view of the above-mentioned conventional problems, and even with a large number of solar cell modules, these solar cell modules can be firmly supported, and the number of components is small. It is an object of the present invention to provide a structure installation stand, a structure installation method, and a solar cell system that are easy to perform.

  In order to solve the above problems, a structure installation stand according to the present invention includes a crosspiece for installing a plurality of structures, and a connection member used for connecting and fixing the structure to the crosspiece. An object installation stand, wherein the crosspiece has a crosspiece main plate and a pair of crosspiece side plates extending in the same direction, and each side of the pair of crosspiece side plates extending in the direction is connected by the crosspiece main plate. A plurality of members are connected, and a part of at least one of the crosspiece main plate ends and each crosspiece side plate end of each of the connected crosspieces is cut out along the direction or at least one of the crosspieces. Each of the crosspiece side plate end portions of each crosspiece member is formed by forming a cut along the direction between the main plate end portion and each crosspiece side plate end portion, and elastic deformation of each crosspiece side plate of each crosspiece member. Are stacked on the outside or the inside of each other side plate end. Each crosspiece side plate end and the other crosspiece side plate end are connected, and the width of the crosspiece main plate of each crosspiece member is the same, and the connecting member is located on the inside of each crosspiece side plate of the crosspiece member or Each of the connection side plates stacked on the outside, and a connection main plate that is bent at the upper edge of each connection side plate and to which the structure is connected and fixed, and the connection side plate and the plate constituting the connection main plate The plate thickness is larger than the plate thickness of the side plate of the crosspiece member.

  In such a structure installation stand of the present invention, the crosspiece has a main plate and a pair of side plates extending in the same direction, and each side of the pair of side plates extending in the direction is connected by the main plate. A plurality of members are connected. Such a cross member has a U-shape or a cross-sectional shape close to a U-shape, has a large section coefficient, and increases the strength of the cross member. For this reason, the intensity | strength of the cross | link which connected the some crosspiece member also becomes high.

  Further, at least one of the crosspiece plate end portions of each connected crosspiece member and a part of each crosspiece side plate end portion are cut out along the direction, or between the crosspiece main plate end portion and each crosspiece side plate end portion in the direction. A cut along the line is formed. Then, each side plate is elastically deformed such that one side plate of each crosspiece member is overlapped on the outside or inside of the other side plate. Accordingly, it is easy to overlap one end of each crosspiece side plate of each crosspiece member on the outside or inside of the other end of each crosspiece side plate. And since each crosspiece member is connected in this state, the side plate of both sides becomes a double structure in the connection location of each crosspiece member, and the intensity | strength improves. Moreover, even if the number of crosspieces is increased in order to extend the crosspieces, only the process of overlapping and connecting one end of each crosspiece side plate on the outside or inside of the other crosspiece side plate end is repeated. Therefore, construction work is easy.

  In such a connection structure, even if the width | variety of the main plate of each connected crosspiece member is the same, each crosspiece member can be connected.

  Moreover, since the plate | board thickness of the board which comprises a connection side plate and a connection main board is thicker than the plate | board thickness of the side plate of a crosspiece member, each crosspiece member can be reinforced and deformation of each crosspiece member can be prevented.

  Moreover, in the structure installation stand of the present invention, the connection member includes a protrusion protruding upward from the connection main plate so as to contact a part of the structure.

  Furthermore, in the structure installation stand of the present invention, the connection main plate of the connection member is overlapped on the inside or outside of the crosspiece main plate of the crosspiece member.

  In the structure installation stand of the present invention, the connection side plate of the connection member is overlapped on the outer side of the beam side plate of the beam member, and the connection main plate of the connection member is an upper edge of the connection side plate. And is bent in the opposite direction to the crosspiece main plate.

  Furthermore, in the structure installation stand according to the present invention, when at least one of the crosspiece main plate ends of each of the connected crosspieces is cut off, one of the crosspiece side plate ends of each of the crosspieces is the other. When the one crosspiece side plate end and the other crosspiece side plate end are connected in a state where they are overlapped on the outside or inside of each crosspiece side plate end, The crosspiece main plate of each crosspiece is separated.

  Thereby, the main plates of the crosspiece members do not interfere with each other, and the end portions of the crosspiece members are easily connected.

  In the structure installation stand of the present invention, each side plate end of one or the other side plate in a state where one side plate end portion of each crosspiece member is overlapped on the outside or inside of the other side plate end portion. A pipe is arranged inside the part, and the bolt is passed through the hole at one end of each side plate, the hole at the end of each other side plate, and the pipe, and a nut is screwed into the end of the bolt and tightened. Thus, the one side plate end and the other side plate end are connected to each other.

  In this case, each crosspiece member end can be connected by one bolt, one pipe, and one nut, and an increase in the number of parts and assembly man-hours can be suppressed.

  Alternatively, in the structure installation stand of the present invention, each side plate end of one or the other side plate in a state where one side plate end portion of each crosspiece member is overlapped on the outside or inside of the other side plate end portion. A cylindrical female screw member is disposed inside the portion, and two bolts are inserted into the female female member inside the cylindrical female screw member from both ends of the cylindrical female screw member through holes in one side plate end portion and the other side plate end portion. The one side plate end portion and the other side plate end portion are connected to each other by being screwed into the screws.

  In this case, the end portions of the crosspiece members can be connected by two bolts and one cylindrical female screw member, and an increase in the number of parts and assembly man-hours can be suppressed.

  Moreover, in the structure installation stand of the present invention, the bending angle of each crosspiece side plate with respect to the crosspiece main plate is set so that the interval between the crosspiece side plates increases as the distance from the crosspiece main plate increases.

  That is, the opening side of the crosspiece member is widened. In this case, each side plate of the other cross member can be easily overlapped inside each side plate of the one cross member only by covering each side plate of the one cross member on each side plate of the other cross member.

  Furthermore, in the structure installation stand according to the present invention, the crosspiece member has a hat-shaped cross section including each crosspiece side plate, the crosspiece main plate, and each crosspiece bent at an edge of each crosspiece side plate. ing.

  The section modulus of the hat-shaped section is larger than the section coefficient of the U-shaped section, and the strength of the crosspiece member is further increased.

  In the structure installation stand of the present invention, the crosspiece is formed by roll forming.

  Roll forming is suitable for mass production of crosspieces, and can reduce the cost of the crosspieces.

  Furthermore, in the structure installation stand according to the present invention, the crosspieces are installed while supporting the vicinity of the connection points of the plurality of crosspiece members connected to form the crosspieces.

  By supporting the vicinity of the connection location, the connection location can be reinforced.

  Further, in the structure installation stand of the present invention, three of the crosspieces are installed side by side, and each structure is bridged and mounted between these crosspieces. The reinforcing member attached only to the thing is provided.

  Here, when mounting each structure between the three crosses, a large load is applied to the central cross and a small load is applied to both crosses. Therefore, if the strength of the three bars is set according to the small load applied to the bars on both sides and the bars are made common, the weight of each bar can be reduced and the cost can be reduced. However, since the strength of the central beam is insufficient, a reinforcing member is attached to the central beam.

  In other words, a structure in which a reinforcing member is attached only to the center of each of the bars, the strength of the three bars is set based on the small load applied to the bars on both sides, and the weight of each bar is reduced. And make it possible to reduce costs.

  If the strength of the three bars is set in accordance with the large load applied to the central bar, even if the bars can be shared, the bars become heavy and the cost increases.

  Furthermore, in the structure installation stand of the present invention, the reinforcing member is attached to one end portion of the crosspiece member of the central crosspiece.

  If the reinforcing members are attached to both ends of the crosspiece member, the number of reinforcing members increases, and the construction work becomes complicated and the cost increases.

  Moreover, in the structure installation stand of the present invention, the reinforcing member has a truss structure.

  Furthermore, in the structure installation stand according to the present invention, three of the crosspieces are installed side by side, and each of the structures is bridged and mounted between these crosspieces. The reinforcing tool is attached only to the rail, and the reinforcing tool is overlapped and fixed near the center of the rail along the longitudinal direction of the rail.

  In this way, the central rail can be reinforced also by providing a reinforcing tool that is superposed and fixed near the center of the rail along the longitudinal direction of the rail only in the central rail.

  Moreover, in the structure installation stand of the present invention, the reinforcing tool connects the structure to the crosspiece.

  Thus, if the reinforcing tool is also used for connecting and connecting the structure to the crosspiece, an increase in the number of parts can be suppressed.

  Next, the construction method of the structure installation stand of the present invention is the construction method of the structure installation stand of the present invention, wherein one of the crosspiece members is caused by elastic deformation of each crosspiece side plate of each crosspiece member. Each of the crosspiece side plate end portions is overlapped on the inside or outside of the other crosspiece side plate end portion, and then the one crosspiece side plate end portion and the other crosspiece side plate end portion are connected.

  In such a construction method of the present invention, even if the number of crosspiece members is increased in order to extend the crosspiece, only such connection work is repeated, and the construction work is easy.

  Moreover, the solar cell system of the present invention includes the above-described structure installation stand of the present invention, and a solar cell module as a structure is mounted on a horizontal rail of the structure installation stand.

  Since the solar cell module has a flat plate shape and is inclined, a large wind pressure is likely to be applied to the front and back of the solar cell module. For this reason, the structure installation stand of the present invention is suitable as a stand for a solar cell system.

  In the present invention, the crosspiece has a main plate and a pair of side plates extending in the same direction, and a plurality of crosspiece members each having a shape in which the sides extending in the direction of the pair of side plates are connected by the main plate are connected. Such a cross member has a U-shape or a cross-sectional shape close to a U-shape, has a large section coefficient, and increases the strength of the cross member. For this reason, the intensity | strength of the cross | link which connected the some crosspiece member also becomes high.

  Further, at least one of the crosspiece plate end portions of each connected crosspiece member and a part of each crosspiece side plate end portion are cut out along the direction, or between the crosspiece main plate end portion and each crosspiece side plate end portion in the direction. A cut along the line is formed. Then, each side plate is elastically deformed such that one side plate of each crosspiece member is overlapped on the outside or inside of the other side plate. Accordingly, it is easy to overlap one end of each crosspiece side plate of each crosspiece member on the outside or inside of the other end of each crosspiece side plate. And since each crosspiece member is connected in this state, the side plate of both sides becomes a double structure in the connection location of each crosspiece member, and the intensity | strength improves. Moreover, even if the number of crosspieces is increased in order to extend the crosspieces, only the process of overlapping and connecting one end of each crosspiece side plate on the outside or inside of the other crosspiece side plate end is repeated. Therefore, construction work is easy.

  In such a connection structure, even if the width | variety of the main plate of each connected crosspiece member is the same, each crosspiece member can be connected.

  Moreover, since the plate | board thickness of the board which comprises a connection side plate and a connection main board is thicker than the plate | board thickness of the side plate of a crosspiece member, each crosspiece member can be reinforced and deformation of each crosspiece member can be prevented.

  Moreover, the length of the crosspiece member 152 is substantially the same as the interval between the vertical crosspieces 14 shown in FIG. 1, and is slightly shorter than the crosspiece member 151.

  FIG. 9 is a perspective view showing the truss 16. As shown in FIG. 9, the truss 16 includes a pair of side plates 16 a facing each other, a main plate 16 b that connects opposite sides of each side plate 16 a, and a hat 16 c that is bent outward at the edge of each side plate 16 a. It has a mold cross-sectional shape.

  At one end portion 16-1 of the truss 16, the main plate 16b and the flanges 16c are cut away, leaving only the side plates 16a. Further, the main plate 16b and the flanges 16c are also cut off at the other end portion 16-2 of the truss 16, leaving only the side plates 16a. Further, respective bolt holes 16 d are formed at both ends of each side plate 16 a of the truss 16.

  Here, each of the base rail 12, the arm 13, the vertical rail 14, the horizontal rail 15, and the truss 16 is bent outward at each side plate, a main plate that connects opposite sides of each side plate, and an edge of each side plate. It has a hat-shaped cross-sectional shape consisting of Moreover, all hat-shaped cross-sectional shapes are the same size. In other words, the width of the main plate and the width of the side plate are the same. Further, both are formed by cutting or punching a plated steel sheet having the same thickness and then bending the plated steel sheet. For this reason, the material and the processing apparatus can be shared, and the cost can be significantly reduced.

  Furthermore, roll forming can be applied to form a plated steel sheet into a hat-shaped cross-sectional shape. In this case, mass production can be performed quickly, and the cost can be further greatly reduced. As described above, since the solar cell system to which the structure installation platform of the present embodiment is applied is premised on the realization of a large-scale power plant, the number of solar cell modules is extremely large. The scale is also large. For this reason, the base beam 12, the arm 13, the vertical beam 14, the horizontal beam 15, and the truss 16 are used in large numbers, and in order to rapidly mass-produce them, roll forming is performed with the same cross-sectional shape and size. Processing is often applied, resulting in a significant cost reduction.

  Further, as shown in FIG. 10, the hat-shaped cross-sectional shapes of the base rail 12, the arm 13, the vertical rail 14, the horizontal rail 15, and the truss 16 are such that the distance between the side plates a increases as the distance from the main plate b increases. Is a shape in which the bending angle α of each side plate a is set. That is, each side plate a spreads on the opening side of the cross-sectional hat shape of the crosspiece, and the width of the main plate b is narrower than the opening portion of the crosspiece. For this reason, as will be described later, the construction work of stacking each side plate of the crosspiece end on the other crosspiece end becomes easy.

  Next, a triangular structure in which the base beam 12, the arm 13, and the vertical beam 14 are assembled on the concrete foundation 11 will be described.

  FIGS. 11A and 11B are a perspective view and a front view showing a triangular structure composed of a base beam 12, an arm 13, and a vertical beam 14, respectively. As shown in FIG. 11, the base beam 12 is fixed to the upper surface 11-1 of the concrete foundation 11, and the arm 13 is connected to the rear end portion 12-1 of the base beam 12 so as to stand upright. 2 and an upper end portion 13-1 of the arm 13 are fixed to the vertical beam 14 in an oblique manner, and a triangular structure including the base beam 12, the arm 13, and the vertical beam 14 is constructed.

  Two bolts 21 are projected in advance on the upper surface 11-1 of the concrete foundation 11, and these bolts 21 are inserted into the respective elongated holes 12d of the main plate 12b of the base bar 12 so as to pass through the main plate of the base bar 12. The base bar 12 is placed with the surface 12b brought into contact with the upper surface 11-1 of the concrete foundation 11. At this time, the base rail 12 and the bolts 21 can be moved along the long holes 12d (in the Y direction in FIG. 1), so that the base rail 12 is moved in the Y direction to adjust the position in the Y direction. Adjust.

  FIG. 12 is a perspective view showing a U-shaped reinforcing bracket 22 used for fixing the base rail 12. The U-shaped reinforcing metal fitting 22 has a main plate 22a and side plates 22b bent at both edges of the main plate 22a, and a bolt hole 22c is formed at the center of the main plate 22a.

  Two such U-shaped reinforcing brackets 22 are used. After the main plate 12b of the base rail 12 is placed on the upper surface 11-1 of the concrete foundation 11, the respective U-shaped reinforcing brackets 22 are inserted into the holes of the two U-shaped reinforcing brackets 22 through the respective bolts 21. Arranged inside the crosspiece 12. At this time, as shown in FIG. 13, the direction of the U-shaped reinforcing bracket 22 is set so that each side plate 22 b of the U-shaped reinforcing bracket 22 is orthogonal to each side plate 12 a of the base bar 12. Each side plate 22b of the reinforcing bracket 22 is brought into contact with the main plate 12b of the base bar 12. Then, each nut 21 is screwed and tightened, whereby the base bar 12 is fixed to the upper surface 11-1 of the concrete foundation 11.

  In this state, the side plates 22b of the U-shaped reinforcing metal fitting 22 are pressed against the main plate 12b of the base beam 12, and the main plate 12b of the base beam 12 is reinforced. Further, since the width of each side plate 22b of the U-shaped reinforcing metal fitting 22 is set to be substantially the same as the interval between the side plates 12a of the base bar 12, each side plate 12a of the base bar 12 is reinforced.

  Thereafter, the arm 13 is connected to the rear end portion 12-1 of the base bar 12 and is erected. At the lower end 13-2 of the arm 13, the main plate 13b and the flanges 13c are cut away, leaving only the side plates 13a. Moreover, as shown in FIG. 10, each side plate 12a of the base crosspiece 12 spreads on the opening side of the hat-shaped cross section. For this reason, while elastically deforming the lower end portions of the side plates 13a so as to approach each other, the lower end portions of the side plates 13a can be easily inserted and sandwiched inside the rear end portions of the side plates 12a of the base bar 12. The lower end of each side plate 13a and the rear end of each side plate 12a can be overlapped. At this time, the arm 13 is self-supporting, and the subsequent connection work of the arm 13 is facilitated.

  In a state where the arm 13 is self-supporting, a pipe 25 is inserted between the side plates 13a of the arm 13 as shown in FIG. 13, and the pipe 25, the bolt holes 13d of the side plates 13a of the arm 13 and the base rails 12 are The bolt hole 12e of the side plate 12a is aligned, and the bolt 26 is passed through the pipe 25, the bolt hole 13d of each side plate 13a of the arm 13, the bolt hole 12e of each side plate 12a of the base rail 12, and the washer. A nut 27 is screwed into and tightened to connect the lower end of each side plate 13 a of the arm 13 to each side plate 12 a of the base bar 12.

  In this way, when the bolt 26 is passed through the pipe 25, the side plates 13a of the arm 13 and the side plates 12a of the base bar 12, and the nut 27 is tightened, the pipe 25 is sandwiched between the side plates 13a and 12a. The side plates are reinforced, and the deformation of the hat-shaped cross-sectional shape (shown in FIG. 10) of the arm 13 and the base bar 12 can be prevented. Further, since the length of the pipe 25 and the distance between the side plates of the crosspiece are equal and the size of the pipe 25 is larger than that of a nut or the like, the workability by manual work is improved. Moreover, since only the pipe 25, the bolt 26, the nut 27, etc. are used one by one, the number of parts, a man-hour, and cost can be reduced.

  Next, the vertical beam 14 is bridged obliquely between the tip portion 12-2 of the base 12 and the upper end portion 13-1 of the arm 13 and fixed. Each ridge 12c is cut off at the tip of the base bar 12. Further, as shown in FIG. 10, each side plate 14a of the vertical beam 14 spreads on the opening side of the hat-shaped cross section. For this reason, the tip of each side plate 12a of the base beam 12 can be easily inserted into the inside of the tip of each side plate 14a of the vertical beam 14 while being elastically deformed so as to approach each other. The front ends of the side plates 14a can be overlapped.

  In this state, as in FIG. 13, pipes are inserted between the side plates 12 a of the base beam 12, and the pipes, the bolt holes 12 e of the side plates 12 a of the base beam 12, and the bolt holes of the side plates 14 a of the vertical beam 14. 14e is aligned, the bolt is passed through the pipe, the bolt hole 12e of each side plate 12a of the base beam 12, the bolt hole 14e of each side plate 14a of the vertical beam 14, and the washer, and a nut is screwed into one end of the bolt and tightened. The front ends of the side plates 14 a of the vertical beam 14 are connected to the side plates 12 a of the base beam 12.

  Similarly, at the upper end 13-1 of the arm 13, since the main plate 13b and the flanges 13c are cut away and only the side plates 13a are left, the upper end portions of the side plates 13a are elastically deformed so as to approach each other. The upper end portion of each side plate 13a can be inserted into the inside of each side plate 14a of the vertical rail 14 while making it happen.

  In this state, as in FIG. 13, a pipe is inserted between the side plates 13 a of the arm 13, and the bolt holes 13 d of the side plates 13 a of the arm 13 and the bolt holes 14 e of the side plates 14 a of the vertical beam 14 are formed. The bolts are passed through pipes, bolt holes 13d of the side plates 13a of the arm 13, bolt holes 14e of the side plates 14a of the vertical rails 14, and washers. A nut is screwed into one end of the bolt and tightened. Are connected to the side plates 14a of the vertical beam 14 respectively.

  In this way, a triangular structure including the base beam 12, the arm 13, and the vertical beam 14 is constructed. This triangular structure can sufficiently withstand both the vertical and horizontal forces without particularly increasing the number of parts.

  Next, a structure for connecting and fixing the beam members 151 and 52 constituting the horizontal beam 15 to the vertical beam 14 will be described.

  FIG. 14 is a perspective view showing a mounting bracket 31 used for connecting and fixing the crosspiece members 151 and 52 of the horizontal crosspiece 15 to the vertical crosspiece 14. The mounting bracket 31 is formed with two screw holes 31b in the main plate 31a, side plates 31c on both sides of the main plate 31a, side plates 31d on the front and rear sides of the main plate 31a, and a double bend. Each T-shaped support piece 31e is protruded from.

  As shown in FIGS. 6 and 11, a pair of T-shaped holes 14 d are formed in the vicinity of both ends and the center of the main plate 14 b of the vertical rail 14. For each pair of T-shaped holes 14d, the mounting bracket 31 is mounted on the main plate 14b of the vertical beam 14, and the respective mounting brackets 31 are arranged at three locations near the center and both ends of the main plate 14b of the vertical beam 14.

  As shown in FIG. 15, the head of each support piece 31e of the mounting bracket 31 is inserted into the slit 14f of each T-shaped hole 14d, and each support piece 31e is moved to the engagement hole 14g of each T-shaped hole 14d. Then, the mounting bracket 31 is attached to the main plate 14b of the vertical beam 14 by hooking the heads of the respective support pieces 31e into the engagement holes 14g of the respective T-shaped holes 14d.

  1 and 16, the beam members 151 and 152 are placed on the main plate 14b of the vertical beam 14 so as to be orthogonal to the vertical beam 14, and the flanges 15c of the beam members 151 and 152 are supported by the mounting bracket 31. It arrange | positions between the heads of the piece 31e. The elongated holes 15g of the flanges 15c of the crosspieces 151 and 152 are overlapped with the screw holes 31b of the mounting bracket 31 via the T-shaped holes 14d of the main plate 14b of the vertical crosspiece 14, and the bolts 32 are attached to the crosspiece 151. , 152 are screwed into the screw holes 31b of the mounting bracket 31 via the long holes 15g of the flanges 15c and the T-shaped holes 14d of the main plate 14b of the vertical rail 14 and temporarily fixed.

  In this temporarily fixed state, the bolts 32 can be moved along the long holes 15g of the flanges 15c of the crosspieces 151 and 152. Therefore, the crosspieces 151 and 152 are moved along the long holes 15g ( (In the X direction in FIG. 1) to adjust the position in the X direction.

  Further, the mounting bracket 31 can be moved along each T-shaped hole 14d of the main plate 14b of the vertical beam 14 (in the longitudinal direction of the vertical beam 14), and the beam members 151 and 152 are also moved together with the mounting bracket 31. Can do. The distance between the three horizontal rails 15 arranged on the vertical rail 14 is adjusted by the movement of the rail members 151 and 152 in the longitudinal direction of the vertical rail 14.

  Thus, after adjusting the position of the three horizontal rails 15 in the X direction and adjusting the interval between the horizontal rails 15, the bolts 32 of the respective mounting brackets 31 are tightened so that the horizontal rails 15 are placed on the vertical rails 14. To fix.

  In this way, the position of the horizontal rail 15 in the X direction can be adjusted. Further, as described above, the base beam 12 can be moved in the Y direction to adjust the position in the Y direction. Therefore, the position of the horizontal beam 15 can be adjusted by adjusting the position of the base beam 12. Can do. Accordingly, the position of the horizontal rail 15 in the XY direction can be adjusted. Further, the interval between the horizontal rails 15 can be adjusted. For this reason, even if there is an error in the position of each concrete foundation 11, each horizontal beam 15 can be accurately positioned by adjusting the position of each horizontal beam 15 in the XY direction and adjusting the interval between the horizontal beams 15. As a result, each solar cell module 17 mounted on each horizontal rail 15 can be accurately positioned.

  Next, the connection structure of the some crosspiece members 151 and 152 which comprise the horizontal crosspiece 15 is demonstrated.

  The crosspiece member 151 shown in FIG. 7 is the first rightmost crosspiece member of the horizontal crosspiece 15 in FIG. 1, and is bridged between the vertical crosspieces 14 of the first and second concrete foundations 11 in FIG. It is fixed to these vertical bars 14 using mounting brackets 31.

  A crosspiece member 152 shown in FIG. 8 is a second or subsequent crosspiece member of the horizontal crosspiece 15 in FIG. 1, and is bridged between the left end portion of the first crosspiece member and the next vertical crosspiece 14. . For example, the second cross member 152 is bridged between the left end portion of the first cross member 151 and the third vertical cross member 14, and the third cross member 152 is the left end portion of the second cross member 152. And the fourth vertical beam 14, and similarly, the nth beam member 152 extends between the left end of the (n−1) th beam member 152 and the (n + 1) th vertical beam 14. Passed. The second and subsequent crosspieces 152 are also fixed to the respective vertical crosspieces 14 using the mounting bracket 31.

  As shown in FIGS. 7A and 7B, the main plate 15b is not cut off at either end of the first crosspiece 151. Further, as shown in FIG. 8, a portion along one side of the main plate 15b and each side plate 15a is cut off at one end portion 152-1 of the second and subsequent crosspiece members 152, and only the side plates 15a and the flanges 15c are left. ing. As shown in FIGS. 1 and 3, one end 152-1 of each of the second and subsequent crosspiece members 152 is connected to the left end of the first crosspiece member.

  For example, as shown in FIG. 17A, the left end of each side plate 15 a of the first cross member 151 is inserted and sandwiched inside one end of each side plate 15 a of the second cross member 152. As shown in FIG. 10, each side plate 15a spreads out on the side of the hat-shaped cross-sectional opening of the horizontal beam 15 (the beam members 151 and 152), so one side end portion of each side plate 15a of the second beam member 152 Is simply put on the left end of each side plate 15a of the first crosspiece 151, and the left end of each first side plate 15a is inserted and sandwiched inside one end of each second side plate 15a. Can do.

  In this state, as shown in FIG. 17 (b), the pipe 25 is inserted between the side plates 15a of the first crosspiece member 151, the pipe 25, the bolt holes 15f of the side plates 15a of the first crosspiece member 151, The bolt holes 15f of the side plates 15a of the second cross member 152 are aligned, the bolts 26 are connected to the pipe 25, the bolt holes 15f of the side plates 15a of the first cross member 151, and the side plates of the second cross member 152. The nut 27 is screwed into one end of the bolt 26 and tightened through the bolt hole 15f and the washer 15a, and the side plates 15a of the second cross member 152 are connected to the side plates 15a of the first cross member 151.

  In addition, one side end portion of each side plate 15a of the third cross member 152 is put on the left end portion of each side plate 15a of the second cross member 151, and the second end is placed inside the one end portion of each third side plate 15a. The left end of each side plate 15a is inserted and sandwiched, and the third side plate 15a is connected to the second side plate 15a by using a pipe 25, a bolt 26, a nut 27, and a washer.

  Similarly, the left end of each side plate 15a of the (n-1) th cross member 151 is inserted and sandwiched inside one end of each side plate 15a of the nth cross member 152, and the pipe 25, bolt 26, nut 27 is inserted. The nth side plate 15a is connected to the (n-1) th side plate 15a by using a washer.

  In this way, one long horizontal beam 15 is configured by connecting a plurality of beam members 151 and 152.

  As is apparent from FIGS. 17A and 17B, the side plates 15a on both sides have a double structure at the connection location of the crosspiece members 151 and 152, and the strength thereof is improved. Moreover, even if the number of the crosspiece members 151 and 152 is increased in order to extend the horizontal crosspiece 15, the construction process is easy because only the same connection process is repeated.

  In addition, since the main plate 15b is cut off at the one end portion 152-1 of the crosspiece member 152, the main plate 15b of each crosspiece member is separated at the connection portion of each crosspiece member. For this reason, the main plates 15b of the cross members do not interfere with each other, and the end portions of the cross members are easily connected.

  Next, a truss structure for reinforcing the central cross rail 15 will be described.

  Here, as shown in FIG. 1, a plurality of solar cell modules 17 are mounted in two rows on the three horizontal rails 15, so that the central horizontal rail 15 has upper and lower horizontal rails. A load greater than 15 is applied. For example, when attention is paid to the upper and lower two solar cell modules 17 on the rightmost side in FIG. 1, the load of 0.5 solar cell modules 17 is applied to the upper and lower horizontal rails 15 respectively. It can be generally considered that a load of 1.0 solar cell modules 17 is applied to the crosspiece 15. Therefore, a load approximately twice as large as that of the upper and lower horizontal rails 15 is applied to the central horizontal rail 15.

  Therefore, if the strength of the three horizontal rails 15 is set according to the small load applied to the upper and lower horizontal rails 15 and each horizontal rail 15 is made common, the weight and cost of each horizontal rail 15 are reduced. Can be reduced. However, since the strength of the central crosspiece 15 is insufficient, two truss 16 are bridged between the base crosspiece 12 and the central crosspiece 15 to reinforce the central crosspiece 15 as shown in FIG. The truss structure is built.

  In other words, the strength of the three horizontal rails 15 is set based on the small load applied to the upper and lower horizontal rails 15 by the structure in which only the middle one of the horizontal rails 15 is reinforced. The weight of each crosspiece 15 is reduced and the cost is reduced.

  In addition, in this embodiment, although the solar cell module 17 was arranged in 2 rows, you may arrange 3 or more rows. In this case, the horizontal rails other than the upper horizontal rail and the lower horizontal rail correspond to the central horizontal rail, and a truss is attached.

  Further, assuming that the rightmost base beam 12 is the first in FIG. 1, a truss structure is provided for each even-numbered base beam 12. As a result, the crosspiece members 151 and 152 of the central crosspiece 15 are reinforced by only one truss 16, and the number of trusses 16 is reduced, thereby preventing the construction work from being complicated and the cost from increasing.

  FIGS. 18 and 19 are a front view and a side view showing the trusses 16 spanned between the base rail 12 and the central horizontal rail 15. As apparent from FIG. 19, when the trusses 16 are viewed from the side, the trusses 16 are arranged perpendicular to the solar cell module 17. This is to prevent the truss 16 from being overturned by the load or wind pressure of the solar cell module 17. Further, in order to arrange each truss 16 perpendicular to the solar cell module 17, it is necessary to support each truss 16 obliquely with respect to the base beam 12. For this reason, the base beam 12 and the two trusses 16 are required. Each side plate 31b of the connection fitting 31 for connecting is inclined.

  FIGS. 20A and 20B are a perspective view and a side view showing a connection fitting 31 for connecting the base bar 12 and the two trusses 16, respectively. The connection fitting 31 has a main plate 31a and side plates 31b bent at both edges of the main plate 31a, and each side plate 31b is inclined with respect to the main plate 31a. Two long holes 31c are formed in the main plate 31a, and bolt holes 31d and screw holes 31e are formed in each side plate 31b.

  The main plate 31a of the connection fitting 31 is placed in the approximate center of each rod 12c of the even-numbered base bar 12, and the two long holes 31c of the main plate 31a are overlapped with the bolt holes 12f of each rod 12c, and two bolts are attached. The nuts are screwed into one end of these bolts through the elongated holes 31c of the main plate 31a and the bolt holes 12f of the flanges 12c, and the connection fittings 31 are temporarily fixed on the flanges 12c of the base bar 12.

  In this temporarily fixed state, since each bolt is passed through each long hole 31c of the main plate 31a of the connection fitting 31, the connection fitting 31 is moved along each long hole 31c (in the X direction in FIG. 1). be able to.

  After temporarily fixing the connection fitting 31, both ends of the two trusses 16 are connected to the connection fitting 31 and the central crosspiece 15. At this time, the end portions (one end portion 16-1 in FIG. 9) of the side plates 16a of the two trusses 16 and the side plates 31b of the connection fitting 31 are overlapped with each other. Then, pipes are inserted between the innermost side plates facing each other, and the pipes, the bolt holes 16d of the side plates 16a of the trusses 16 and the holes 31d and 31e of the side plates 31b of the connection fitting 31 are aligned. The bolt is passed through the pipe, the bolt hole 16d of each side plate 16a of the two trusses 16, the bolt hole 31d of the side plate 31b of the connection fitting 31, and the washer, and one end of the bolt is threaded 31e of the side plate 31b of the connection fitting 31. Then, the ends of the two trusses 16 are temporarily fixed to the connection fitting 31.

  Further, for both of the two trusses 16, the end portions of the side plates 16a of the truss 16 are elastically deformed so that the end portions (the other end portion 16-2 in FIG. 9) approach each other. The portion is inserted inside the side plate 15a of the crosspiece member 151 or 152 of the central horizontal crosspiece 15. Then, pipes are inserted between the side plates 16a of the truss 16, the bolt holes 16d of the side plates 16a of the truss 16 and the bolt holes 15f of the side plates 15a of the crosspieces 151 or 152 are aligned, and the bolts are The nuts are screwed into one end of the bolts through the bolt holes 16d of the side plates 16a of the pipe and truss 16, the bolt holes 15f of the side plates 15a of the cross members 151 or 152, and washers. Temporarily fix to the member 151 or 152.

  When attaching each truss 16 as described above, the end of each side plate 16a of each truss 16 (the other in FIG. 9) is moved while the connection fitting 31 is moved along each elongated hole 31c (in the X direction in FIG. 1). It is necessary to adjust the position of the end portion 16-2) to align the bolt hole 16d at the end portion of each side plate 16a with the bolt hole 15f of each side plate 15a of the crosspiece member 151 or 152. As described above, the crosspieces 151 and 152 of the crosspiece 15 are moved in the X direction to adjust the position of the crosspiece 15 in the X direction. This is because it is necessary to shift the position of each truss 16 by the position adjustment.

  After connecting both ends of each truss 16 to the connection fitting 31 and the central crosspiece 15, each bolt for connecting both ends of each truss 16 is tightened to fix each truss 16.

  Next, a structure for mounting the solar cell module 17 on the horizontal rail 15 will be described.

  Here, as is clear from FIG. 1, the central horizontal beam 15 supports the ends of the upper and lower solar cell modules 17, and the upper and lower horizontal beams 15 are the upper or lower solar cell module 17. The end of the is supported. For this reason, the mounting structure of the solar cell module 17 is different between the central horizontal rail 15 and the upper and lower horizontal rails 15. These mounting structures will be described separately.

  FIGS. 21A, 21B, and 21C are a front view showing the first connection fitting disposed on the back side of the solar cell module 17 in the central cross rail 15, and the first connection fitting seen from the front and back. FIG. The first connection fitting 41 has a side plate 41a and a main plate 41b bent at the upper edge of the side plate 41a. The main plate 41b is formed with a hanging piece 41e that is bent at the central portion of one side of the main plate 41b and a protruding portion 41f that is bent and raised at both ends of the one side of the main plate 41b. Further, a screw hole 41d is formed in the approximate center of the main plate 41b, and a bolt hole 41c is formed in the side plate 41a. The height of the side plate 41a is substantially equal to the height of the side plate 15a of the horizontal rail 15.

  22A and 22B are a perspective view and a plan view showing a reinforcing metal fitting used together with the first connecting metal fitting 41 of FIG. The reinforcing metal fitting 42 has a hat-shaped cross-sectional shape including a pair of side plates 42a facing each other, a main plate 42b connecting one side of each side plate 42a, and a flange 42c that is bent at the edge of each side plate 42a and protrudes outward. The width is set so as to be fitted inside the horizontal rail 15.

  Each side plate 42a of the reinforcing metal fitting 42 is formed with a screw hole 42d, and each flange 42c is formed with a long hole 42e.

  FIG. 23 is a perspective view showing the first fixing fitting disposed on the light receiving surface side of the solar cell module 17. The first fixing fitting 43 is formed by forming a protruding piece 43b bent downward at the front and rear end portions of the pressing plate 43a and forming a bolt hole 43c at the central portion of the pressing plate 43a.

  FIG. 24 is a perspective view showing the second fixing bracket disposed on the light receiving surface side of the solar cell module 17. The second fixing bracket 44 has a protruding piece 44b bent downward at the front and rear end portions of the pressing plate 44a, a bolt hole 44c formed at the central portion of the pressing plate 44a, and perpendicular to one end edge of the pressing plate 44a. A standing wall 44d is formed, and the bottom edge 44e is formed by bending the lower edge of the standing wall 44d.

  All of the first connection fitting 41, the reinforcing fitting 42, and the first and second fixing fittings 43 and 44 are made of steel plates that are sufficiently thicker than the base rail 12, the arm 13, the vertical rail 14, the horizontal rail 15, and the truss 16. It has a high strength.

  Here, two first connection fittings 41 are arranged in pairs at the positions where the pair of slits 15d and bolt holes 15e are formed in the main plate 15b of the crosspieces 151 and 152 of the central crosspiece 15 as shown in FIG. As described above, the side plates 41a of the two first connection fittings 41 are stacked on the side plates 15a of the horizontal rails 15, and the main plates 41b of these first connection fittings 41 are directed so as to protrude outward from the horizontal rails 15, Each protrusion 41f of the first connection fitting 41 protrudes upward from the main plate 15b of the cross rail 15.

  Similarly to the first connection fitting 41, the reinforcing fitting 42 is also arranged at a position where the pair of slits 15 d and the bolt hole 15 e are formed in the main plate 15 b of the central transverse rail 15 and is fitted inside the lateral rail 15. As shown in FIG. 25, the side plates 42 a of the auxiliary metal fittings 42 are overlapped with the lower portions of the side plates 15 a of the horizontal rails 15, and the flanges 42 c of the auxiliary metal fittings 42 are overlapped with the flanges 15 c of the horizontal rails 15.

  Then, as shown in FIG. 25, two bolts are connected to each side plate 42a of the auxiliary fitting 42 through the bolt holes 41c of each side plate 41a of the first connection fitting 41 and the bolt holes 15f of each side plate 15a of the horizontal rail 15. Each screw hole 42d is screwed and tightened. For this reason, in the site | part of the 1st connection metal fitting 41, a side plate and a collar become a double or triple structure, and the intensity | strength in this site | part becomes high.

  Incidentally, since the first crosspiece 151 on the rightmost side of the central crosspiece 15 in FIG. 1 has a pair of slits 15d and bolt holes 15e formed in four places as shown in FIG. Two first connection fittings 41 are provided at each location, and one auxiliary fitting 42 is provided at each of the four locations. Further, as shown in FIG. 8, a pair of slits 15d and bolt holes 15e are formed in three places in the second and subsequent crosspiece members 151 of the horizontal crosspiece 15. Therefore, the first connection fitting 41 is provided in these three places. Are provided two by two, and one auxiliary metal fitting 42 is provided at each of the three locations.

  In addition, at both ends of the crosspiece member 151 shown in FIG. 7, the elongated holes 42e of the flanges 42c of the auxiliary metal fitting 42 overlap the elongated holes 15g of the flanges 15c of the crosspiece member 151. Further, also at one end portion of the crosspiece member 152 shown in FIG. 8, the long holes 42 e of the respective flanges 42 c of the auxiliary metal fitting 42 overlap the long holes 15 g of the respective flanges 15 c of the crosspiece member 152. Therefore, the elongated holes 15g of the flanges 15c of the crosspieces 151 and 152 are not blocked by the flanges 42c of the auxiliary metal fitting 42, and the lengths of the elongated holes 15g are not limited. The movement of the crosspiece members 151 and 152 along the shape hole 15g (X direction in FIG. 1) is not hindered.

  FIG. 26A is a plan view showing a state in which four solar cell modules 17 are attached to the central cross rail 15 using the first connection fitting 41, the reinforcement fitting 42, and the first fixing fitting 43. It is. Moreover, FIG.26 (b) is sectional drawing which follows BB of Fig.26 (a), and is sectional drawing which follows FIG.25 (c) CC. Further, FIG. 27 is a perspective view showing the state of FIG. 26 as viewed from the light receiving surface side of the solar cell module.

  26 (a), (b), and (c), the frame member 19 of each of the lower left and right solar cell modules 17 is inserted between the protrusions 41f of the lower first connection fitting 41, and the horizontal rails are inserted. It is placed on 15 main plates 15b. At this time, each solar cell module 17 is connected to the main plate 15b of the horizontal rail 15 until the inner edge 19a of the frame member 19 of each of the lower left and right solar cell modules 17 comes into contact with each protrusion 41f of the lower first connection fitting 41. The upper and lower positions of each solar cell module 17 are positioned by shifting upward.

  Then, as shown in FIGS. 26 (a), (b), and FIG. 27, the projection pieces 43 b of the first fixing bracket 43 are inserted between the frame members 19 of the lower left and right solar cell modules 17 to The frame members 19 of the battery modules 17 are spaced apart by a fixed interval, and at the same time, the bottom projections 19b of the frame members 19 of the solar cell modules 17 are connected to the projections 41f of the first connection fitting 41 as shown in FIG. The left and right positions of the solar cell modules 17 are positioned.

  Subsequently, the bolt 45 is screwed into the screw hole 41d of the main plate 41 of the first connection fitting 41 via the gap between the bolt hole 43c of the first fixing fitting 43 and the frame member 19 of each of the lower left and right solar cell modules 17 and tightened. Include. As a result, the frame members 19 of the lower left and right solar cell modules 17 are sandwiched and fixed between the first fixture 43 and the main plate 15b of the horizontal rail 15.

  Similarly, the frame members 19 of the upper left and right solar cell modules 17 are placed between the protrusions 41 f of the upper first connection fitting 41 and placed on the main plate 15 b of the horizontal rail 15. At this time, the frame members 19 of the upper left and right solar cell modules 17 are brought into contact with the frame members 19 of the lower left and right solar cell modules 17 to position the vertical positions of the upper left and right solar cell modules 17. And each protrusion piece 43b of the 1st fixing bracket 43 is inserted between the frame members 19 of each of the upper left and right solar cell modules 17, and the bottom protrusion 19b of the frame member 19 of each solar cell module 17 is connected to the first connection bracket 41. The left and right positions of the solar cell modules 17 are positioned in contact with the projections 41f.

  Subsequently, the bolt 45 is screwed into the screw hole 41d of the main plate 41 of the first connection fitting 41 through the gap between the bolt hole 43c of the first fixing fitting 43 and the frame member 19 of each of the upper left and right solar cell modules 17 and tightened. The frame members 19 of the upper left and right solar cell modules 17 are fixed.

  On the other hand, the second fixing bracket 44 is used to fix the upper and lower two solar cell modules 17 located on the rightmost or left side in FIG.

  As shown in FIG. 28, the frame member 19 of the rightmost or leftmost solar cell module 17 is placed between the protrusions 41 f of the first connection fitting 41 and placed on the main plate 15 b of the horizontal rail 15. Then, the bottom piece 44e of the second fixing bracket 44 is placed on the main plate 15b of the horizontal rail 15, and each protruding piece 44b of the second fixing bracket 44 is pressed against the frame member 19 of the solar cell module 17, so that the solar cell module 17 The bottom projection 19b of the frame member 19 is brought into contact with the projection 41f of the first connection fitting 41, and the left and right positions of the solar cell module 17 are positioned.

  Then, the bolt 45 is screwed into the screw hole 41 d of the main plate 41 b of the first connection fitting 41 through the bolt hole 44 c of the second fixing fitting 44 and tightened. As a result, the frame member 19 of the solar cell module 17 is sandwiched and fixed between the second fixing bracket 44 and the main plate 15 b of the horizontal rail 15.

  Here, as described above, in the portion of the first connection fitting 41 and the auxiliary fitting 42, the side plate 15a of the cross rail 15, the side plate 41a of the first connection fitting 41, and the side plate 42a of the auxiliary fitting 42 are double or three. In addition, since the flange 15c of the horizontal rail 15 and the flange 42c of the auxiliary bracket 42 are doubled, the strength at this portion is increased. Further, since the main plate 15b of the crosspiece 15 and the side plates 15a and the main plate 42 of the auxiliary metal fitting 42 have a square closed structure, this also increases the strength at the portion.

  Further, when a strong wind pressure is applied to the front and back surfaces of the solar cell module 17, the central portion of the solar cell module 17 is bent by the wind pressure, and the frame member 19 of the solar cell module 17 is removed from the locking portion due to the influence. A strong force is generated. However, in the present embodiment, even if wind pressure is applied to the front and back surfaces of the solar cell module 17, the projection 41 f of the first connection fitting 41 is caught inside the frame member 19 of the solar cell module 17, and the frame of the solar cell module 17. Since the member 19 is sandwiched between the first connection fitting 41 and the first or second fixing fitting 43, 44, the frame member 19 of the solar cell module 17 is not detached.

  Further, the set of two first connection fittings 41 is disposed so as to face each other via the horizontal rail 15, and is arranged vertically symmetrically with respect to the center line S (shown in FIG. 26A) of the horizontal rail 15. . Then, the bolts 45 for fixing the upper and lower solar cell modules 17 are screwed into the screw holes 41 d of the first connection fittings 41, and the bolts 45 are also vertically moved with respect to the center line S of the horizontal rail 15. They are arranged symmetrically.

  A force is generated at the position of the protrusion 41f of the first connection fitting 41 and the first or second fixing fitting 43, 44 due to the influence of the wind pressure. If this layout design is mistaken, this force is applied to the horizontal rail 15 or the solar cell module 17. A force acts so as to twist the frame member 19, and these are deformed. However, as shown in FIG. 26, the protrusions 41 of the pair of first connection fittings 41 are on a straight line parallel to the bolt 45 of the first or second fixing fitting 43, 44 and the center line S of the crosspiece 15. Since the bolts 45 and the projections 41f of the first or second fixing brackets 43 and 44 are arranged vertically symmetrically with respect to the center line S of the horizontal rail 15, the force due to the influence of wind pressure is lateral. It does not act to twist the crosspiece 15 or the frame member 19 of the solar cell module 17, and these do not deform.

  In order to prevent this twisting force, it is most preferable to arrange the protrusions 41f of the two first connection fittings 41 and the bolts 45 of the first or second fixing fittings 43 and 44 on the center line S of the horizontal rail 15. Although it is desirable, since the frame members 19 of the upper and lower solar cell modules 17 cannot be fixed together on the center line S of the horizontal rail 15 as is apparent from FIG. 26, the protruding portions 41 f of the two first connection fittings 41. The bolts 45 of the first or second fixing brackets 43 and 44 are provided at positions symmetrical with respect to the center line S of the horizontal rail 15.

  Further, since each bolt 45 is screwed into the screw hole 41 d of the first connection fitting 41 that is sufficiently thicker than the horizontal rail 15, each bolt 45 is not pulled out by the wind pressure applied to the solar cell module 17.

  That is, each of the projections 41f and the bolts for forming a double or triple structure and a closed structure by the horizontal rail 15, the first connection fitting 41, and the auxiliary fitting 42, and for fixing the upper and lower solar cell modules 17 to each other. 45 is arranged symmetrically with respect to the center line S of the horizontal beam 15 and each bolt 45 is screwed into the screw hole 41d of the sufficiently thick first connection fitting 41, so that the load resistance of the horizontal beam 15 is greatly increased. Has improved.

  FIG. 29A is a perspective view showing a second connection fitting disposed on the back side of the solar cell module 17 in the upper and lower horizontal rails 15. FIGS. 29B (a) and 29 (b) are a plan view and a side view showing the second connection fitting of FIG. 29A. The second connection fitting 51 is a hat-type comprising a pair of side plates 51a facing each other, a main plate 51b connecting the opposing sides of each side plate 51a, and a flange 51c that is bent at the edge of each side plate 51a and protrudes outward. It has a cross-sectional shape and is set to a shape and size that fits inside the horizontal rail 15.

  L-shaped cuts are respectively formed from both ends of the main plate 51b of the second connection fitting 51 to the inside, and the insides of these L-shaped cuts are raised to form projections 51f. Further, each side plate 51a of the second connection fitting 51 is formed with a screw hole 51d, a screw hole 51e is formed on the center line of the main plate 51b, and each elongated hole 51g is formed in each flange 51c. .

  The second connection fitting 51 is formed by processing a sufficiently thick steel plate similarly to the first connection fitting 41, the reinforcing fitting 42, and the first and second fixing fittings 43 and 44, and has high strength.

  Such second connection fittings 51 are respectively arranged at positions where the pair of slits 15d and bolt holes 15e are formed in the main plate 15b of the upper and lower horizontal rails 15 and are fitted inside the horizontal rails 15.

  As shown in FIG. 30, when the second connection fitting 51 is fitted inside the horizontal rail 15, the projections 51 f of the main plate 51 b of the second connection fitting 51 are formed from the pair of slits 15 d of the main plate 15 b of the horizontal rail 15. Projects upward.

  Further, the side plates 51 a of the second connection fitting 51 overlap the side plates 15 a of the horizontal rail 15, the main plate 51 b overlaps the main plate 15 b of the horizontal rail 15, and the flanges 51 c overlap the flanges 15 c of the horizontal rail 15.

  In this state, the two bolts are respectively screwed and tightened into the screw holes 51d of the side plates 51a of the second connection fitting 51 through the bolt holes 15f of the side plates 15a of the horizontal rail 15. For this reason, in the site | part of the 2nd connection metal fitting 51, a main board, a side board, and a collar become double structure, and the intensity | strength in this site | part becomes high.

  Incidentally, since the rightmost first rail member 151 of the upper and lower horizontal rails 15 in FIG. 1 has a pair of slits 15d and bolt holes 15e formed in four places as shown in FIG. The second connection fittings 51 are provided at these four locations. Moreover, since the pair of slits 15d and the bolt holes 15e are formed in three places in the second and subsequent crosspiece members 151 of the horizontal crosspiece 15 as shown in FIG. 8, the second connection fitting 51 is provided in these three places. Is provided.

  In addition, at both ends of the crosspiece member 151 shown in FIG. 7, the long holes 51 g of the flanges 51 c of the second connection fitting 51 overlap the long holes 15 g of the hooks 15 c of the crosspiece member 151. Further, also at one end portion of the crosspiece member 152 shown in FIG. 8, the long holes 51 g of the flanges 51 c of the second connection fitting 51 overlap the long holes 15 g of the flanges 15 c of the crosspiece member 152. Therefore, the elongated holes 15g of the flanges 15c of the crosspieces 151, 152 are not blocked by the flanges 51c of the second connection fitting 51, and the length of the elongated holes 15g is not limited. The movement of the crosspiece members 151 and 152 along the long hole 15g is not obstructed.

  FIG. 31A is a plan view showing a state in which the left and right solar cell modules 17 are attached to the upper and lower horizontal rails 15 using the second connection fitting 51 and the first fixing fitting 43. . Moreover, FIG.31 (b) is sectional drawing which follows BB of Fig.31 (a), and is sectional drawing which follows CC of FIG.31 (c).

  31 (a), 31 (b), and 31 (c), the frame member 19 of each of the left and right solar cell modules 17 is inserted between the projections 51f of the second connection fitting 51, and on the main plate 15b of the horizontal rail 15. Placed on. Then, the protruding pieces 43b of the first fixing bracket 43 are inserted between the frame members 19 of the left and right solar cell modules 17, and the frame members 19 of the solar cell modules 17 are separated by a predetermined interval. The bottom protrusion 19b of the frame member 19 of the battery module 17 is brought into contact with each protrusion 51f of the second connection fitting 51, and the left and right positions of the solar cell modules 17 are positioned.

  Subsequently, the main plate 51 of the second connection fitting 51 is connected to the bolt 45 through the bolt hole 43c of the first fixing fitting 43, the gap between the frame members 19 of each solar cell module 17, and the bolt hole 15e of the main plate 15b of the horizontal rail 15. And screwed into the screw hole 51e. As a result, the frame member 19 of each solar cell module 17 is sandwiched and fixed between the first fixing fitting 43 and the main plate 15b of the horizontal rail 15.

  In general, in consideration of workability, the connection fitting is arranged so as to support the lower side of the lower solar cell module 17. However, since the first connection fitting 41 used above is positioned in the vertical direction at the central crosspiece 15, the fixing location by the second connection fitting 51 is on the side of the solar cell module 17 in the water flow direction. Good. For this reason, it becomes possible to make the space | interval of the connection metal fittings 41 and 51 shorter than the side of the water flow direction of the solar cell module 17 without impairing workability. The same applies to the distance between the connection fittings 41 and 51 of the upper solar cell module 17 that is positioned by being supported by the lower solar cell module 17. As a result, it is possible to make the vertical rail 14 shorter than the length of the upper and lower solar cell modules 17 in the water flow direction, and it is possible to reduce the size of the gantry.

  Further, the second fixing bracket 44 is used to fix the upper and lower two solar cell modules 17 located on the rightmost or left side in FIG. As shown in FIG. 32, the frame member 19 of the rightmost or leftmost solar cell module 17 is placed between the protrusions 51 f of the second connection fitting 51 and placed on the main plate 15 b of the horizontal rail 15. Then, the bottom piece 44e of the second fixing bracket 44 is placed on the main plate 15b of the horizontal rail 15, and each protruding piece 44b of the second fixing bracket 44 is pressed against the frame member 19 of the solar cell module 17, so that the solar cell module 17 The bottom protrusion 19b of the frame member 19 is brought into contact with the protrusion 51f of the second connection fitting 51, the left and right positions of the solar cell module 17 are positioned, and the bolt 45 is connected to the bolt hole 43c and the horizontal rail 15 of the second fixing fitting 44. And screwed into the screw hole 51e of the main plate 51 of the second connection fitting 51 through the bolt hole 15e of the main plate 15b. As a result, the frame member 19 of the solar cell module 17 is sandwiched and fixed between the second fixing bracket 44 and the main plate 15 b of the horizontal rail 15.

  Here, since the side plate, the main plate, and the flange have a double structure in the portion of the second connection fitting 51 as described above, the strength in this portion is increased.

  Further, when a strong wind pressure is applied to the front and back surfaces of the solar cell module 17, the central portion of the solar cell module 17 is bent by the wind pressure, and the frame member 19 of the solar cell module 17 is removed from the locking portion due to the influence. A strong force is generated. However, in the present embodiment, even if wind pressure is applied to the front and back surfaces of the solar cell module 17, the protrusion 51 f of the second connection fitting 51 is caught inside the frame member 19 of the solar cell module 17, and the frame of the solar cell module 17. Since the member 19 is sandwiched between the second connection fitting 51 and the first or second fixing fitting 43, 44, the frame member 19 of the solar cell module 17 is not detached.

  Further, a bolt hole 15e is formed on the center line S (shown in FIG. 31A) of the main plate 15b of the horizontal rail 15, and a screw hole 51e is formed on the center line S of the main plate 51b of the second connection fitting 51. ing. Then, a bolt 45 for fixing the solar cell module 17 is screwed into the screw hole 51e through the bolt hole 15e, and the bolt 45 is centerline S of the main plate 15b of the horizontal rail 15 and the main plate 51b of the second connection fitting 51. Is placed on top.

  Thus, the protrusion 51f of the second connection fitting 51 is generally disposed on the center line S of the horizontal rail 15, and the bolts 45 of the first or second fixing bracket 43, 44 are also on the center line S of the horizontal rail 15. Since they are arranged, the force due to the influence of the wind pressure hardly acts to twist the horizontal beam 15 or the frame member 19 of the solar cell module 17, and these do not deform.

  In order to prevent this twisting force, it is ideal that the protrusion 51f and the bolt 45 of the second connection fitting 51 are on the center line S of the horizontal rail 15. However, the strength of the second connection fitting 51 is considered. Therefore, it is necessary to secure a distance between the L-shaped cut area for forming the protrusion 51f from the side plate 51a and the protrusion 51f is provided at a position slightly shifted from the center line S. However, since the bolts 45 of the first or second fixing brackets 43 and 44 are on the center line S of the horizontal rail 15, the influence of the twisting force is minimized.

  In addition, since the bolt 45 is screwed into the screw hole 51e of the second connection fitting 51 that is sufficiently thicker than the horizontal rail 15, the bolt 45 is not pulled out by wind pressure applied to the solar cell module 17.

  That is, the horizontal beam 15 and the second connection fitting 51 constitute a double structure, and the protrusion 51f and the bolt 45 for fixing the solar cell module 17 are arranged on the center line S of the horizontal beam 15, and the bolt Since 45 is screwed into the screw hole 51e of the sufficiently thick second connection fitting 51, the load resistance of the crosspiece 15 is greatly improved.

  Next, the construction procedure of the solar cell system of FIG. 1 will be described with reference to FIGS. 33 to 44.

  First, as shown in FIG. 1, a plurality of concrete foundations 11 are formed on the ground at equal intervals, and their upper surfaces 11-1 are horizontal and flush with each other to form a horizontal foundation surface.

The crosspiece 12 is moved in the Y direction to adjust the position in the Y direction. Then, the respective U-shaped reinforcing brackets 22 are arranged inside the base bar 12 through the respective bolts 21 through the holes of the two U-shaped reinforcing brackets 22, and the respective nuts are screwed into the respective bolts 21 and tightened. And fix the base bar 12.

As described above, the pipe is connected between the side plates 13a of the arm 13. The bolt is passed through the pipe, the bolt hole 13d of each side plate 13a of the arm 13, the bolt hole 12e of each side plate 12a of the base bar 12, and the washer, and a nut is screwed into one end of the bolt and tightened. The lower ends of the 13 side plates 13 a are fixed to the side plates 12 a of the base bar 12.

  As shown in FIG. 35, a vertical beam 14 is obliquely bridged and fixed between the tip of the base 12 and the upper end of the arm 13. The pipe 12, the bolt, the washer, the nut, and the like are also connected between the tip of the base 12 and the vertical beam 14 and between the upper end of the arm 13 and the vertical beam 14.

  As shown in FIG. 36, the mounting bracket 31 is attached to a pair of T-shaped holes 14d formed in the main plate 14b of the vertical beam 14. Since a pair of T-shaped holes 14d are formed at three locations on the main plate 14b of the vertical beam 14, the mounting bracket 31 is attached to each location.

  As shown in FIG. 37, for each concrete foundation 11, a triangular structure including a base beam 12, an arm 13, and a vertical beam 14 is constructed. In addition, for each of the vertical rails 14, mounting brackets 31 are attached to three locations on the main plate 14 b.

  As shown in FIG. 38, the first connection fitting 41 and the reinforcement fitting 42 are attached to the crosspiece members 151 and 152 that become the horizontal crosspiece 15 at the center.

  As shown in FIG. 39, the 2nd connection metal fitting 51 is attached to the crosspieces 151 and 152 used as the upper and lower horizontal crosspieces 15. As shown in FIG.

  As shown in FIG. 40, three crosspiece members 151 are bridged between the vertical crosspieces 14 of the first and second concrete foundations 11 on the rightmost side, and each crosspiece member 151 is attached to the vertical crosspiece 14 for each vertical crosspiece 14. It is fixed with three mounting brackets 31. As shown in FIG. 38, the central crosspiece 151 is provided with the first connection fitting 41 and the reinforcing fitting 42, and the upper and lower crosspieces 151 are provided with the second connection fitting 51 as shown in FIG. It is attached. At this time, each crosspiece 151 is moved in the X direction to adjust the position in the X direction. Further, the interval between the crosspieces 151 is adjusted.

  As shown in FIG. 41, each crosspiece member 151 is slightly longer than the interval between the vertical crosspieces 14, and the left end portion of each crosspiece member 151 extends beyond the second vertical crosspiece 14.

  As shown in FIGS. 41 and 42, the one end 152-1 of the second lower beam member 152 is placed on the left end of the first beam member 151 protruding from the second vertical beam 14, The ends of the crosspieces 151 and 13 are connected by pipes, bolts, washers, nuts, and the like. At this time, as shown in FIG. 10, each side plate 15a spreads out on the opening side of the hat-shaped cross-sectional shape of the crosspiece members 151 and 152, so that one end of each side plate 15a of the second crosspiece member 152 is 1 By simply covering the left end of each side plate 15a of the second cross member 151, the left end of each first side plate 15a can be inserted and sandwiched inside one end of each second side plate 15a. . At the same time, the left end of the second lower beam member 152 is placed on the third vertical beam 14, and the left end of the beam member 152 is fixed by the mounting bracket 31 of the vertical beam 14. In the same procedure, the second center and upper cross members 152 are bridged and fixed between the left ends of the first center and upper cross members 151 and the third vertical beam 14.

  With respect to the third cross member 152, the left end of the second cross member 152 protrudes beyond the third vertical cross 14 as shown in FIG. It is bridged between the left end of the crosspiece member 152 and the fourth vertical crosspiece 14 and fixed.

  Similarly, the n-th beam member 152 is fixed between the left end portion of the (n−1) -th beam member 152 and the (n + 1) -th vertical beam 14.

  As apparent from FIGS. 41 and 42, the horizontal beam 15 is constructed by placing the vicinity of the connecting portion of the beam members 151 and 152 on the vertical beam 14. Thereby, the connection location of each crosspiece member 151 and 152 is reinforced, and the strength of the entire horizontal crosspiece 15 is improved.

  As shown in FIG. 43, for each even-numbered base beam 12, a truss structure for reinforcing the central horizontal beam 15 is constructed by spanning two trusses 16 between the base beam 12 and the central horizontal beam 15. To do.

  As shown in FIG. 44, the frame member 19 of each of the upper, lower, left, and right solar cell modules 17 is fixed by the first connection fitting 41, the second connection fitting 51, the first fixing fitting 43, and the second fixing fitting 44. At this time, as described above, the inner edge 19a of the frame member 19 of the lower solar cell module 17 is brought into contact with the protrusion 41f of the lower first connection fitting 41 on the central horizontal rail 15, The upper and lower positions of the lower solar cell module 17 are positioned, and thereafter, the frame member 19 of the upper solar cell module 17 is brought into contact with the frame member 19 of the lower solar cell module 17, so that the upper solar cell module 17. Position the vertical position of.

  As is apparent from FIG. 44, two first or second fixing metal fittings 43 and 44 and one first and second connection metal fittings 41 and 51 are arranged on each side of the solar cell module 17. Thus, the side is fixed at two places with a shorter interval than the side of the solar cell module 17. For this reason, the arrangement | positioning space | interval of a fixing metal fitting and a connection metal fitting can be narrowed, the length of the vertical rail 14 can be made shorter than the side of the solar cell module 17, and size reduction of a structure installation stand can be achieved.

  As mentioned above, although the embodiment of the present invention has been described in detail, the present invention is not limited to the above-described embodiment, and even if a design change or the like in a category not departing from the gist of the present invention is performed, It is included in the scope of the present invention.

  For example, the gantry of the above embodiment is constructed by combining a base beam, an arm, a vertical beam, a horizontal beam, and a truss, but may have other structures, such as a base beam, an arm, a vertical beam, and a truss. A crosspiece may be bridged by using a member instead of.

  In addition, a plurality of crosspiece members are connected to form a horizontal crosspiece. However, other types of crosspieces such as a vertical crosspiece and a base crosspiece are long and constituted by a single member. When it is difficult to do this, other crosspieces may be configured by connecting a plurality of crosspiece members.

  Further, in the above embodiment, as shown in FIG. 8, the main plate 15b and a portion along one side of each side plate 15a are cut off at one end portion 152-1 of the crosspiece member 152, leaving only the side plates 15a and the flanges 15c. However, as shown in FIG. 45 (a), at one end portion 152-1 of the crosspiece member 152, a portion 15h along the opposite side of each side plate 15a is cut away so that each side plate 15a is separated from the main plate 15b. I do not care. Also in this case, as shown in FIGS. 45 (b) and 45 (c), the end portions of the side plates 15a of the other cross members 151 or 152 inside or outside the one end portions 152-1 of the side plates 15a of the cross members 152. Can be easily superimposed.

  Further, in any one end portion 152-1 of the crosspiece member 152 in FIGS. 8 and 45 (a), the end portion of the other crosspiece member 151 or 152 is covered outside the one end portion 152-1. It is also possible to overlap and connect the end portions of the crosspiece members.

  Furthermore, as shown in FIG. 17B and the like, the crosspieces may not only be connected to each other using pipes, bolts, and nuts, but may be connected by other methods. For example, as shown in FIG. 46, a cylindrical female screw member 61 is inserted between each side plate 15a of the cross member, and two bolts 62 are inserted from both ends of the cylindrical female screw member 61 through the bolt holes 15f of each side plate 15a of each cross member. The crosspiece members may be connected by screwing into the female screw inside the cylindrical female screw member 61 and tightening. Also in this case, the cylindrical female screw member 61 is sandwiched between the side plates 15a, the side plates are reinforced, and deformation of the cross-sectional shape of the crosspiece member can be prevented. Further, since the length of the cylindrical female screw member 61 is equal to the distance between the side plates, and the size of the cylindrical female screw member 61 is larger than that of a nut or the like, the workability in manual work is improved. Further, since only the cylindrical female screw member 61 and the two bolts 62 are used, the number of parts, man-hours, and cost can be reduced.

  Also, a hat-shaped cross-sectional shape consisting of a pair of side plates, a main plate that connects opposite sides of each side plate, and each ridge bent outward at the edge of each side plate as a base beam, arm, vertical beam, horizontal beam, truss However, instead of this, it is possible to apply one having a U-shaped cross-sectional shape including a pair of side plates and a main plate that connects opposite sides of each side plate. Or you may combine these cross-sectional shapes suitably.

  Furthermore, although the 1st connection metal fitting 41 and the reinforcement metal fitting 42 are used together, the reinforcement metal fitting fitted inside the 2nd connection metal fitting 51 may be provided. The cross-sectional shape of these reinforcing metal fittings may be either a hat-shaped or a U-shaped, and in any case, the cross-sectional shape of the horizontal beam 15 is a rectangular closed structure to improve the strength of the horizontal beam 15. Can do.

  Moreover, in the mount frame of this embodiment, although the solar cell module is supported, you may support the reflector panel used for solar thermal power generation instead. Thereby, a solar thermal power generation system can be constructed.

  Further, in the present embodiment, the main plate end and the side plate end are partially cut away, but each side plate end can be formed by only making a cut in a portion where the main plate and the side plate are in contact (one side between the main plate and the side plate). Can be elastically deformed, so that each cross member can be connected by overlapping each side plate end of another cross member on the inside or outside of each side plate end of the cross member.

  Further, in the present embodiment, a set of two first connection fittings 41 are arranged vertically symmetrically with respect to the center line S of the crosspiece 15, and each bolt 45 is also vertically arranged with respect to the centerline S of the horizontal crosspiece 15. Although it arrange | positions symmetrically, in the range in which the same effect is acquired, you may arrange | position each 1st connection metal fitting 41 or each volt | bolt 45 a little from the vertically symmetrical position.

  Similarly, the bolt hole 15e of the main plate 15b of the cross rail 15 is formed on the center line S, and the screw hole 51e of the second connection fitting 51 is formed on the center line S. The bolt hole 15e or the screw hole 51e may be formed slightly shifted from the center line S.

  In addition, in the gantry of the present embodiment, steel is mainly used as a material, but each side plate end of one cross member is connected to each side plate end of the other cross member between cross members having the same size and the same cross-sectional shape. In order to overlap the portion, it is necessary to elastically deform each side plate end portion of the crosspiece member by the thickness of each side plate by human power. For this reason, it is desirable that the thickness of at least the crosspiece member is 2.0 mm or less, and in order to realize good workability, it is preferably 1.6 mm or less. On the other hand, since it is necessary to ensure the strength of the crosspiece member for supporting the structure, it is desirable that the thickness of the crosspiece member be 0.5 mm or more.

  Furthermore, you may change suitably the shape and structure of a 1st or 2nd connection metal fitting. FIG. 47 is a perspective view showing a modified example of the first connection fitting for attaching the solar cell module 17 to the central cross rail 15. FIG. 48 is a cross-sectional view showing a state where the first connection fitting of FIG. 47 is attached to the central cross rail.

  The first-A connection fitting 71 of this modification is caused by bending at the side plate 71a, the bottom plate 71b bent at the lower edge of the side plate 71a, the main plate 71c bent at the upper edge of the side plate 71a, and both ends of one side of the main plate 71c. Each projection 71e has a screw hole 71f formed in the approximate center of the main plate 71c, and a bolt hole 71g formed in the approximate center of the side plate 71a.

  Further, a U-shaped notch is formed at the upper position of the bolt hole 71g in the side plate 71a of the first A connection fitting 71, and this U-shaped inner portion is opposite to the bottom plate 71b and the main plate 71c from the side plate 71a. The claw portion 71h is pushed out to the side.

  The height from the lower surface of the bottom plate 71b of the first A connection fitting 71 to the upper surface of the main plate 71c is higher than the height from the upper surface of the flange 15c of the central cross rail 15 to the upper surface of the main plate 15b. Specifically, the height to the upper surface of the main plate 71c of the first A connection fitting 71 is made higher by the plate thickness of the fitting than the height to the upper surface of the main plate 15b of the cross rail 15.

  The first A connecting fitting 71 is similar to the first connecting fitting 41 shown in FIGS. 21A to 21C. The pair of slits 15d and the bolt holes 15e in the main plate 15b of the central cross rail 15 (see FIG. 3 and the like). ) Are arranged in pairs, and the side plates 71a of the two first A connection fittings 71 are overlapped on the side plates 15a of the horizontal rails 15, and the main plate 71c of each first A connection fitting 71 is connected to the horizontal rail 15 The protrusions 71e of the first A connecting fittings 71 protrude upward from the main plate 15b of the horizontal rail 15.

  At this time, the claw portion 71h of the side plate 71a of each 1A connection fitting 71 engages with an engagement hole (not shown) of each side plate 15a of the horizontal beam 15, and each 1A connection fitting 71 of the horizontal beam 15 Temporarily fixed to each side plate 15a. Here, it is assumed that an engagement hole is formed at an appropriate location of each side plate 15a of the cross rail 15.

  Further, by setting the height from the lower surface of the bottom plate 71b of the first A connection fitting 71 to the upper surface of the main plate 71c as described above, the upper surface of the main plate 71c of the first A connection fitting 71 is more than the upper surface of the main plate 15b of the cross rail 15. Increases by the thickness.

  In this state, the pipe 72 is inserted between the side plates 15a of the horizontal rail 15, and the pipe 72, the bolt holes 15f of the side plates 15a of the horizontal rail 15, and the bolt holes 71g of the side plates 71a of the first A connection fittings 71 are formed. The bolt 73 is passed through the pipe 72, the bolt hole 15 f of each side plate 15 a of the crosspiece 15, the bolt hole 71 g of the side plate 71 a of each 1A connection fitting 71, and a washer. The first A connection fittings 71 are fixed to the crosspieces 15 by screwing and tightening.

  49, the frame member 19 of the solar cell module 17 is placed between the protrusions 71e of the first A connecting fitting 71 and placed on the main plate 71c, and the second fixing fitting 44 (or the first fixing fitting) is placed. 43) is pressed against the frame member 19 of the solar cell module 17, and the bolt 45 is pushed through the bolt hole 44c of the second fixing bracket 44 (or the bolt hole 43c of the first fixing bracket 43) to the main plate of the first A connecting bracket 71. The frame member 19 of the solar cell module 17 is sandwiched and fixed between the second fixing fitting 44 (or the first fixing fitting 43) and the main plate 71c of the first A connecting fitting 71 by screwing into the screw hole 71f of 71c.

  In this state, the upper surface of the main plate 71c of the first A connection fitting 71 is higher than the upper surface of the main plate 15b of the horizontal beam 15 by the thickness of the metal plate, so that the frame member 19 of the solar cell module 17 is the main plate of the horizontal beam 15. It floats from the upper surface of 15b. For this reason, a path for allowing water to escape is formed between the frame member 19 of the solar cell module 17 and the main plate 15b of the cross rail 15, and the occurrence of rusting of the member can be prevented. In the present embodiment, the metal plate is made thicker, but for the same purpose, the same effect can be obtained even if the crosspiece is made thicker.

  FIG. 50 is a perspective view showing another modification of the first connection fitting. The 1B connecting bracket 81 of this modification is raised by bending at a plurality of locations on one side of the side plate 81a, the bottom plate 81b bent at the lower edge of the side plate 81a, the main plate 81c bent at the upper edge of the side plate 81a, and the main plate 81c. Each projection 81e, two screw holes 81f formed in the main plate 81c, bolt holes (not shown) formed in a plurality of locations on the side plate 81a, and two claw portions 81h. The first B connection fitting 81 is longer than the width of the solar cell module 17.

  There are five protrusions 81e, four notches 81i and 81j are formed between the protrusions 81e, and screw holes 81f of the main plate 81c are formed at the two notches 81i on both ends. . The distance between the two screw holes 81 f is slightly longer than the width of the solar cell module 17.

  The height from the bottom surface of the bottom plate 81b to the top surface of the main plate 81c of the first B connection fitting 81 is made higher by the thickness of the bracket than the height from the top surface of the flange 15c of the central cross rail 15 to the top surface of the main plate 15b.

  As shown in FIG. 51, the first B connection fitting 81 is used together with the first A connection fitting 71 shown in FIGS. The first B connection fittings 81 are arranged in pairs at the center of the central crosspiece 15, and the first A connection fittings 71 are arranged in pairs at both ends of the central crosspiece 15. In each of the first A connection fitting 71 and the first B connection fitting 81, the side plates 71a and 81a are overlapped on the side plates 15a of the horizontal beam 15, and the main plates 71c and 81c protrude outward from the horizontal beam 15. The protrusions 71e and 81e protrude upward from the main plate 15b of the horizontal rail 15. Further, the claw portions 71h and 81h of the side plates 71a and 81a are engaged with the engagement holes (not shown) of the side plates 15a of the horizontal rail 15, so that the first A connection fitting 71 and the first B connection fitting 81 are lateral. Temporarily fixed to each side plate 15a of the crosspiece 15. Further, the upper surfaces of the main plates 71c and 81c are higher than the upper surface of the main plate 15b of the cross rail 15 by the thickness of the metal fitting.

  In this state, in the same way as in FIG. 48, for the first A connection fitting 71, the pipe 72 is inserted between the side plates 15a of the horizontal beam 15, the bolt 73 is connected to the pipe 72, and the bolt hole 15f of each side plate 15a of the horizontal beam 15. Then, the nuts 74 are screwed into one end of the bolts 73 and tightened by passing them through the bolt holes 71g of the side plates 71a of the first A connection fittings 71 and the washers, and the first A connection fittings 71 are fixed to the horizontal rails 15. As for the 1B connecting bracket 81, a pipe 72 is inserted between the side plates 15a of the horizontal rail 15, the bolt 73 is connected to the pipe 72, the bolt hole 15f of each side plate 15a of the horizontal rail 15, and the first B connecting bracket 81. Then, the nut 74 is screwed into one end of the bolt 73 and tightened to pass through the bolt hole of the side plate 81a and the washer, and each 1B connecting bracket 81 is fixed to the horizontal rail 15. Since the four bolt holes are formed in the side plate 81a of the first B connection fitting 81, the first B connection fitting 81 is attached to the horizontal rail 15 by using the pipe 72, the bolt 73, and the nut 74 for each of these bolt holes. Fix it.

  Thereafter, the frame members 19 of the upper and lower two solar cell modules 17 are placed between the first A connecting fitting 71 and the first B connecting fitting 81 at one end of the horizontal rail 15, and the upper and lower two solar panels are also placed on the first B connecting fitting 81. The frame member 19 of the battery module 17 is placed, and the frame members 19 of the two upper and lower solar cell modules 17 are also placed between the first A connection fitting 71 and the first B connection fitting 81 at the other end of the horizontal rail 15. A total of six frame members 19 of the solar cell modules 17 are placed on the horizontal rail 15.

  In the first A connection fitting 71, the frame member 19 of the solar cell module 17 is fixed as shown in FIG.

  Further, in the 1B connection fitting 81, the locations of the two cutout portions 81i on both ends correspond to the space between the projections 71e of the first A connection fitting 71, and the frame of the two solar cell modules 17 adjacent to the left and right. The member 19 is inserted into the cutout portion 81i and placed on the main plate 81c. Similarly to FIG. 27, the first fixing fitting 43 is inserted between the frame members 19 of the solar cell modules 17, and the bolt 45 is inserted. Each solar cell module is screwed into the screw hole 81 f of the main plate 81 c of the first B connection fitting 81 through the bolt hole 43 c of the first fixing fitting 43 and tightened between the first fixing fitting 43 and the main plate 81 c of the first B connection fitting 81. 17 frame members 19 are sandwiched and fixed.

  Further, both sides of the frame member 19 of one solar cell module 17 are arranged in the two notches 81 i at both ends, and the first fixing fittings 43 are pressed against both sides of the frame member 19 of the solar cell module 17. The two bolts 45 are screwed into the screw holes 81 f of the main plate 81 c of the first B connection fitting 81 through the bolt holes 43 c of the first fixing fittings 43. Therefore, the distance between each screw hole 81f must be slightly longer than the width of the solar cell module 17 so that the solar cell module 17 can be disposed in the space between the two screw holes 81f.

  Even when such a first B connection fitting 81 is used together with the first A connection fitting 71, the upper surface of the main plate 71c of the first A connection fitting 71 and the upper surface of the main plate 81c of the first B connection fitting 81 are more fitting than the upper surface of the main plate 15b of the cross rail 15. Therefore, a path for allowing water to escape is formed between the frame member 19 of the solar cell module 17 and the main plate 15b of the horizontal rail 15, and the occurrence of rusting of the member can be prevented.

  In addition, since the first B connection fitting 81 is longer than the width of the solar cell module 17, the distance that the side plate 81a and the bottom plate 81b of the first B connection fitting 81 overlap the side plate 15a and the flange 15c of the central cross rail 15 is increased. When the 1B connecting bracket 81 is fixed to the central crosspiece 15, the central crosspiece 15 is effectively reinforced. Accordingly, the first B connection fitting 81 not only supports the frame members 19 of the three solar cell modules 17, but also serves as a reinforcement for the central crosspiece 15. Since a larger load is applied to the central side rail 15 than the upper and lower side rails 15, such reinforcement of the central side rail 15 is beneficial.
