It was supposed to flow. As a configuration for ensuring the electrical conductivity between the solar panel and the gantry, in Patent Document 1, in order to increase the electrical conductivity between the members, a minute protrusion is provided on the surface of the frame on which the solar panel is placed, and the solar panel The structure which bites into the insulating film of the member of the side is disclosed.

JP 2007-2111435 A

  By the way, in recent years, in order to reduce the weight of the gantry, a member constituting the solar panel gantry is often made of an aluminum alloy. However, such a member is subjected to a corrosion-resistant coating treatment on the surface. In many cases, the electrical conductivity between members is reduced. However, as can be seen from the pedestal in Patent Document 1, since the minute projections are formed on the frame itself constituting the pedestal, there is a problem that a lot of work is required. Moreover, although there existed a structure which ensures the electrical conductivity between a solar panel and a mount like patent document 1, the electrical conductivity between the members which comprise a mount was not considered.

  In addition, the processing cost is high to form the microprojections, and if the microprojections are provided not only on the solar panel but also on the members constituting the solar panel mount, the processing cost of the solar panel mount is reduced. There was a problem that it increased significantly.

  From such a viewpoint, an object of the present invention is to provide an energizing member and a fixing structure that can easily and easily increase the conductivity between members.

  The invention according to claim 1 for solving such a problem is an energization member for improving the conductivity between members when the members used in the photovoltaic power generation apparatus are fixed to each other using bolts and nuts. The metal plate material is clamped between the members by tightening the bolt and the nut, and the metal plate material projects to a bolt through hole into which the shaft portion of the bolt is inserted and to one member side. It is an electricity supply member provided with the 1st electricity supply protrusion to perform, and the 2nd electricity supply protrusion which protrudes in the other member side.

  According to such a configuration, since the first energizing protrusion and the second energizing protrusion are bitten into each member only by a simple operation of sandwiching the energizing member between the members, there is a corrosion-resistant coating on the surface. Even if it does, the electrical conductivity between members can be raised easily. In addition, the first energizing protrusion and the second energizing protrusion can be formed only by bending the plate material, and can be processed relatively inexpensively.

  The invention according to claim 2 is characterized in that the first energizing protrusion and the second energizing protrusion are formed by bending a protruding corner of the metal plate material.

  According to such a configuration, the energization member can be easily bent.

  The invention according to claim 3 is characterized in that the member is made of an aluminum alloy, and the metal plate is made of stainless steel.

  According to such a configuration, the first energizing protrusion and the second energizing protrusion made of relatively hard stainless steel easily bite into a member made of aluminum alloy that is softer than the first energizing protrusion.

  The invention which concerns on Claim 4 is clamped by the 1st member provided with the accommodation groove | channel in which the head of a volt | bolt is accommodated, the 2nd member fixed to said 1st member, said 1st member, and said 2nd member. A pair of engaging portions extending inward from the groove sidewalls on both sides are formed in the receiving groove, and the shaft portion of the bolt is inserted into the energizing member. A bolt through hole; a first energizing protrusion protruding toward the first member; and a second energizing protrusion protruding toward the second member. A fixing structure characterized in that the member and the second member are tightened so that the first energizing protrusion bites into the locking portion and the second energizing protrusion bites into the second member. is there.

  According to such a fixing structure, the first energizing protrusion bites into the locking portion of the first member and the first energizing protrusion is bitten between the first member and the second member by a simple operation. Since the second energizing protrusions bite into the two members, even if there is a corrosion-resistant coating or the like on the surface of the members, the conductivity between the members can be easily increased.

  The invention according to claim 5 is characterized in that the first member and the second member are made of an extruded shape made of an aluminum alloy.

  According to such a feature, it is possible to obtain the first member and the second member that are reduced in weight and have high accuracy.

  In the invention according to claim 6, the first member is a member constituting a solar panel mount for supporting the solar panel, and the second member is the solar panel or the solar panel mount. It is a constituent member.

  According to such a structure, the solar power generation device with high electroconductivity between the members of a solar panel and a solar panel mount, and between the members of a solar panel mount can be obtained.

  According to the current-carrying member and the fixing structure according to the present invention, the current-carrying property between the members can be easily increased at low cost.

The first reinforcing member 50 includes a substrate portion 51 and a temporary fixing wall portion 52 that hangs down from the substrate portion 51. The board part 51 is a part sandwiched between the head of the bolt B and the locking part 13. The substrate part 51 is formed thicker than the locking part 13. The substrate portion 51 has a width dimension larger than the width of the gap between the locking portions 13 and 13. When the first reinforcing member 50 is accommodated in the accommodating groove 11, both end portions in the width direction of the substrate portion 51 come into contact with the lower surfaces of the locking portions 13 and 13. In a state where the first reinforcing member 50 is fixed, the upper surface of the substrate portion 51 is pressed against the lower surface of the locking portion 13 to generate a frictional force. Two bolt through holes 53 and 53 are formed in the substrate portion 51 at intervals in the extrusion direction (see FIG. 6). A shaft portion of the bolt B for fixing the rafter 30 to the rafter receiver 10 is inserted into the bolt through hole 53. The distance between the bolt through holes 53 and 53 is such that the lower end of the rafter 30 can be disposed between the bolts B and B.

  Two rows of guide grooves 54 and 54 along the extrusion direction are formed on the upper surface of the substrate portion 51. The guide groove 54 is formed at a position corresponding to the guide protrusion 14 of the locking portion 13. The two rows of guide grooves 54 and 54 are parallel to each other. The guide protrusion 14 enters the guide groove 54. A portion of the substrate portion 51 sandwiched between the two rows of guide grooves 54 and 54 has a surface protruding upward, and is thicker than portions on both sides thereof. The protruding dimension is substantially the same as the thickness dimension of the locking portion 13. When the first reinforcing member 50 is received in the upper receiving groove 11 a, the outer surface of the locking portion 13 and the thick plate portion of the substrate portion 51 are arranged. The surface becomes substantially flush.

The front end portion of the pressing portion 91a is inclined so that the lower surface approaches the upper surface toward the front end and gradually becomes thinner. The intermediate portion in the width direction of the substrate portion 91 is a portion that covers the upper portion of the gap between the solar panels 2 and 2. A bolt through hole 93 is formed in the intermediate portion in the width direction.

  The insertion plate portion 92 is a plate portion that is inserted into a gap between the adjacent solar panels 2 and 2. The insertion plate portion 92 includes a first plate portion 92a and a second plate portion 92b. The first plate portion 92a and the second plate portion 92b are parallel to each other, and have a separation dimension through which the shaft portion of the bolt B can be inserted. The first plate portion 92a has a lower length than the second plate portion 92b. The first plate portion 92 a has a lowered length that is longer than half of the thickness dimension of the solar panel 2. The 1st board part 92a contact | abuts to the upper edge end surface 2a of the solar panel 2 located in the inclination direction lower side. The second plate portion 92b has a lowering length that is shorter than half the thickness of the solar panel 2. The 2nd board part 92b contact | abuts to the lower edge end surface 2b of the solar panel 2 located in the inclination direction upper side.

  By adopting such a configuration, for example, when the solar panel 2 is attached and installed in order from the lower side in the inclination direction, the lower solar panel in the bolt groove between the two solar panels 2 and 2. When the long first plate portion 92a of the pressing member 91 is brought into contact with the upper end portion of the second pressing member 91, the pressing member 91 is stabilized, so that the pressing member 90 does not fall down. Therefore, the mounting operation can be smoothly performed in the order of the lower solar panel 2, the pressing member 90, and the upper solar panel 2. Furthermore, the bolt B between the solar panels 2 and 2 is a relatively long bolt, but if the lowering length of at least one insertion plate portion 92 of the pressing member 90 is long, the solar panel 2 and 2 is long. There is also an advantage that a width for inserting the bolt B is easily secured. If both of the lowering lengths of the insertion plate portions 91 are short, there is a problem that the lower distance between the solar panels 2 and 2 may be reduced. However, the lowering length of at least one insertion plate portion 92 is reduced. The above problem is solved by lengthening the length.

  As shown in FIG. 14 and FIG. 15, the second energization member 85 is a member for enhancing the conductivity between the rafter 30 and the solar panel 2. The second energizing member 85 is made of a metal plate material. The metal plate material includes a bolt through hole 86 through which the shaft portion of the bolt B is inserted, a first energizing protrusion 87 protruding toward one member (rafter 30), and the other member (solar panel 2) side. And a second energizing protrusion 88 that protrudes from the center.

  The metal plate is made of stainless steel. The metal plate material has a shape in which each side of a regular dodecagon is cut out in a V shape inside, and each protruding corner is a right angle. In other words, the outer diameter of the metal plate material has a shape in which three same-shaped squares are shifted in phase by 60 degrees by superimposing respective gravity centers (intersection positions of diagonal lines). The metal plate is sized so as not to protrude from the upper end surface of the rafter 30 (the upper surfaces of the locking portions 35 and 35 and the upper surfaces of the upper flange portions 32b and 32b). The bolt through hole 86 is formed at the center of gravity of the metal plate material. The shaft portion of the bolt B is inserted into the bolt through hole 86.

  The first energizing protrusion 87 is formed at the protruding corner of the metal plate material. The first energizing protrusion 87 is raised so as to be substantially perpendicular to the surface of the metal plate material.

  The second energizing protrusion 88 is formed at the protruding corner of the metal plate material. The second energizing protrusion 88 is raised so as to face in the opposite direction to the first energizing protrusion 87 and to be substantially perpendicular to the surface of the metal plate material.

  The first energizing protrusion 87 and the second energizing protrusion 88 are formed by bending a triangular portion of the protruding corner portion of the metal plate material with a press. The first energizing protrusion 82 and the second energizing protrusion 83 have a thin tip at the time of bending press processing, and the cross-sectional shape is an acute wedge shape with a sharp tip. In addition, the energization protrusions 87 and 88 of the second energization member 85 are triangular in plan view.

  As shown in FIG. 13, the second energization member 85 is disposed between the upper surfaces of the locking portions 35 and 35 of the rafter 30 and the lower surfaces of the solar panels 2 and 2. The first energizing protrusion 87 bites into the outer surface of the locking part 35 (see the partially enlarged view of FIG. 11), and the second energizing protrusion 88 bites into the lower surface of the solar panel 2.

  The bolt B has a length such that the tip of the shaft portion protrudes upward from the pressing member 90 spanned on the upper surface of the solar panel 2. The bolt B is housed in the housing groove 34 with the shaft portion facing upward, and the projecting shaft portion passes through the bolt through hole 86 of the second energizing member 85 and the bolt through hole 93 of the pressing member 90. And protrudes above the pressing member 90. A nut N is screwed to the tip of the shaft portion of the bolt B, and the pressing member 90 presses the solar panel 2 with its tightening force. And the 2nd electricity supply member 85 will be clamped by the solar panel 2 and the rafter 30. FIG. Since the 1st electricity supply protrusion 87 bites into the outer surface of the latching | locking part 35, and penetrates the corrosion-resistant coating layer of the surface of the latching | locking part 13, the electroconductivity with the 2nd electricity supply member 85 and the rafter 30 is ensured. . On the other hand, since the 2nd electricity supply protrusion 88 bites into the lower surface of the solar panel 2, and penetrates the corrosion-resistant coating layer of the surface of the solar panel 2, the electrical conductivity of the 2nd electricity supply member 85 and the solar panel 2 is Secured.

Below, the procedure which fixes the rafter receptacle 10 and the rafter 30 via the 1st electricity supply member 80 with the fixing structure of the member which concerns on this embodiment is demonstrated.
As shown in FIG. 4, first, the shaft portions of the bolts B and B are inserted into the bolt through holes 53 and 53 from the lower surface (surface on which the bolt rotation preventing protrusions 56 a and 56 b are formed) side of the first reinforcing member 50. Insert. Then, the first reinforcing member 50 and the bolts B and B are inserted from the end portions of the housing grooves 11, and the desired end portion of the shaft portion of the bolt B is projected from the gap between the locking portions 13 and 13. It is moved along the longitudinal direction of the groove to a position (position where the rafter 30 is fixed). At this time, the first reinforcing member 50 is slightly smaller than the internal dimension of the receiving groove 11, so that it does not get caught on the inner surface of the receiving groove 11. Further, since the guide protrusion 14 on the lower surface of the locking portion 13 enters the guide groove 54 on the upper surface of the substrate portion 51, the first reinforcing member 50 moves smoothly along the accommodation groove 11. Furthermore, since the lower end portion of the temporary fixing wall portion 52 is in contact with the bottom portion of the housing groove 11, the first reinforcing member 50 is placed in the housing groove 11 while the inclination angle of the first reinforcing member 50 is kept constant. Can be easily moved. When the first reinforcing member 50 is moved to a predetermined position, the screw Va is inserted into the screw hole 15 of the rafter receiver 10 and the screw hole 55 of the first reinforcing member 50, and the first reinforcing member 50 is attached to the rafter receiver 10. Temporarily fix.

  In this state, the rafter receiver 10 is transported to the site. Since the 1st reinforcement member 50 is temporarily fixed to the rafter receptacle 10 at the time of conveyance, the 1st reinforcement member 50 can be conveyed in the stable state, without rattling.

  Then, at the construction site of the solar panel mount, after the rafter receiver 10 is installed on the support column 40, the first energizing member 80 is mounted on the shaft portions of the bolts B and B protruding from the rafter receiver 10, and the bolt through holes 81 are installed. , 81 is inserted through the shafts of the bolts B, B. At this time, it arrange | positions so that the 1st electricity supply protrusion 82 which protrudes toward the rafter receptacle 30 may become the lower side of an inclination direction.

  Thereafter, the rafter 30 is installed between the shafts of the bolts B and B protruding from the first energizing member 80. The rafter 30 is installed across the pair of front and rear rafter receivers 10 and 10 so that the longitudinal direction thereof is orthogonal to the longitudinal direction of the rafter receiver 10. Here, the rafter 30 is placed on the first energizing member 80. At this time, a positioning screw Vb for determining the position of the rafter 30 relative to the rafter receiver 10 in the longitudinal direction is attached. The positioning screw Vb is struck from the lower side of the locking plate piece 32a so that the head of the positioning screw Vb protrudes from the bottom surface of the locking plate piece 32a. When the head of the positioning screw Vb is locked to the corner of the upper end surface of the rafter receiver 10, the longitudinal position of the rafter 30 is easily determined.

  Further, since the first reinforcing member 50 is temporarily fixed at a desired installation position, the protruding shaft portion of the bolt B serves as a guide for the installation position of the rafter 30 with respect to the rafter receiver 10. Therefore, the rafter 30 can be easily positioned in the longitudinal direction of the rafter receiver 10 only by being installed between the shaft portions of the bolts B and B. Therefore, installation work becomes easy.

  Then, the 2nd reinforcement members 70 and 70 are installed so that the front-end | tip part of the latching plate piece 32a of the rafter 30 may be hold | suppressed. The second reinforcing member 70 is lowered from above the bolt B with the leg portion 72 on the lower side, and the shaft portion of the bolt B is inserted into the bolt through hole 73. Then, a nut N is attached to the tip of the shaft portion of the bolt B protruding from the substrate portion 71 of the second reinforcing member 70 and tightened. At this time, the head of the bolt B is in a state in which the rotation is prevented by the bolt rotation preventing protrusions 56a and 56b, and therefore the nut N can be easily tightened. By this tightening, the bolt B and the nut N clamp and clamp the first reinforcing member 50, the second reinforcing member 70, the locking portion 13, the first energizing member 80, and the locking plate piece 32a. And the leg part 72 of the 2nd reinforcement member 70 presses the 1st electricity supply member 80, and the 1st electricity supply member 80 presses the latching | locking part 13 of the rafter receptacle 10. FIG. Further, the pressing portion 74 of the second reinforcing member 70 presses and holds the end portion of the locking plate piece 32 a, and the locking plate piece 32 a presses the first energizing member 80. After the final fastening of the nut N to the bolt B is completed, the screw Va may be removed or may remain attached.

  According to the fixing structure having such a configuration, the first energizing protrusion 82 of the first energizing member 80 bites into the outer surface of the locking portion 13 and thus penetrates the corrosion-resistant coating layer on the surface of the locking portion 13. Thereby, the electrical conductivity of the 1st electricity supply member 80 and the rafter receptacle 10 is ensured. Further, the second energizing protrusion 83 of the first energizing member 80 bites into the lower surface of the rafter 30 (the lower surface of the locking plate piece 32 a) and the lower end of the leg portion 72 of the second reinforcing member 70. Here, since the 2nd electricity supply protrusion 83 has digged into the lower surface of the latching plate piece 32a, it penetrates the corrosion-resistant coating layer on the surface of the latching plate piece 32a. Thereby, the electrical conductivity of the 1st electricity supply member 80 and the rafter 30 is ensured. In other words, according to the fixed structure, the conductivity of the rafter receiver 10 and the rafter 30 can be ensured via the first energization member 80. As a result, even if a leakage or lightning strike occurs in one member of the rafter receiver 10 and the rafter 30, charging within one member can be prevented.

  In the present embodiment, the first energizing protrusion 82 and the second energizing protrusion 83 have cross-sectional shapes that are pointed at the tips, and thus easily bite into the surface of the rafter receiver 10 or the rafter 30. In particular, the rafter receiver 10 and the rafter 30 are made of an aluminum alloy, and the first energizing member 80 is made of stainless steel that is harder than the aluminum alloy. The protrusion 83 tends to bite into the surface of the rafter receiver 10 or the rafter 30.

  Since the first energizing protrusion 82 and the second energizing protrusion 83 are formed by bending the edge of the metal plate material with a press, the first energizing protrusion 82 and the second energizing protrusion 83 can be processed with relatively high accuracy and high accuracy. Further, since the first energizing protrusion 82 and the second energizing protrusion 83 are bent at approximately 90 degrees with respect to the metal plate material, the first energizing protrusion 82 and the second energizing protrusion 83 are difficult to spread when biting into the surface of the rafter receiver 10 or the rafter 30 (before processing). It is difficult to return to the shape). Furthermore, as shown in FIG. 8, the first energizing protrusion 82 is disposed on the lower side of the tilt direction, and the second energizing protrusion 83 is disposed on the upper side of the tilt direction. The one energizing protrusion 82 and the second energizing protrusion 83 act in a direction of further bending with respect to the metal part plate material. Accordingly, the first energizing protrusion 82 and the second energizing protrusion 83 are difficult to spread when biting in, and the load of the rafter 30 is such that the first energizing protrusion 82 and the second energizing protrusion 83 are the rafter receiver 10 and the rafter 30. In addition, it acts in the direction of biting.

  On the other hand, according to the present embodiment, the first reinforcing member 50 can increase the contact area with the locking portion 13. Even if the rafter 30 is pulled away from the rafter receiver 10 by the wind pressure (negative pressure) in the direction of lifting the solar panel 2 (the rafter 30 is pulled in the direction in which it is lifted), the first reinforcing member 50 The pressing force (supporting pressure from the head of the bolt B) that moves upward is distributed over a wide area and acts on the locking portion 13. As a result, the surface pressure applied to the locking portion 13 can be reduced, so that deformation (rolling up) of the locking portion 13 can be suppressed. Therefore, it can withstand a large negative pressure.

  In particular, in the present embodiment, the first reinforcing member 50 has a width dimension substantially equal to the distance between the upper end portions of the groove side walls 12a and 12b of the receiving groove 11, so that the first reinforcing member 50 has a width dimension. Can be maximized. Thereby, the contact area to the latching | locking part 13 of the 1st reinforcement member 50 can be enlarged, and the opposition performance with respect to a negative pressure can be improved. Furthermore, since the board | substrate part 51 of the 1st reinforcement member 50 is formed thicker than the latching | locking part 13, it can disperse | distribute and transmit the supporting pressure which acts intensively from the head of the volt | bolt B over a wide range. .

  Further, the first reinforcing member 50 is configured to pass through the shaft portions of a pair of bolts B and B adjacent to each other in the housing groove 11 along the longitudinal direction of the groove, and both end portions of the second reinforcing members 70 and 70. Since it is formed longer than the distance between them, the contact area of the first reinforcing member 50 to the locking portion 13 can be further increased. Therefore, the surface pressure applied to the locking portion 13 can be further reduced. Further, since the contact area of the first reinforcing member 50 with the locking portion 13 is increased, the frictional force between the first reinforcing member 50 and the locking portion 13 can be increased, and the first reinforcing member 50 in the longitudinal direction of the groove can be increased. Slip can be suppressed. Furthermore, since two bolts B and B are fixed by one first reinforcing member 50, the first reinforcing member 50 is compared with the case where the first reinforcing member 50 is provided for each bolt B and B. Installation effort can be reduced.

  Further, in the first reinforcing member 50, the temporary fixing wall portion 52 and the bolt rotation preventing protrusions 56a and 56b serve as reinforcing ribs, so that the first reinforcing member 50 can be efficiently reduced in weight. In addition, the cross-sectional rigidity of the first reinforcing member 50 can be increased. Also in the second reinforcing member 70, the leg portion 72 serves as a reinforcing rib. Therefore, it is possible to efficiently increase the cross-sectional rigidity of the second reinforcing member 70 while reducing the weight of the second reinforcing member 70. it can.

  Furthermore, since the latching | locking part 13 is pinched | interposed by the latching plate piece 32a and the width direction both ends of the 1st reinforcement member 50, and the leg part 72 of the 2nd reinforcement member 70, the latching | locking part 13 is pressed down from front and back both surfaces. As a result, the deformation of the locking portion 13 can be further suppressed.

  Further, the rafter 30 is supported by the second reinforcing member 70 at both sides in the width direction and is firmly locked by tightening the bolts B and nuts N, so that the fixing strength of the rafter receiver 10 and the rafter 30 can be increased. . In particular, since the second reinforcing member 70 is formed in an L-shaped cross section, the tightening force by the bolt B and the nut N is easily transmitted to the locking plate piece 32a and the locking portion 13, so that the locking plate The force which presses the piece 32a can be enlarged.

  Furthermore, since the rising portion 33 of the locking plate piece 32a enters the concave groove 75 of the pressing portion 74, the fixing strength of the rafter receiver 10 and the rafter 30 can be further increased. Specifically, when the rising portion 33 is engaged with the concave groove 75, the rafter 30 can be reliably prevented from shifting in the width direction. Furthermore, since the contact area between the locking plate piece 32a and the second reinforcing member 70 can be increased, the frictional force generated between the rafter 30 and the second reinforcing member 70 can be increased. Therefore, it is possible to prevent the rafter 30 from shifting in the longitudinal direction.

Below, the procedure which fixes the rafter 30 and the solar panel 2 via the 2nd electricity supply member 85 with the fixing structure of the member which concerns on this embodiment is demonstrated.
After the solar panel mount 1 is completed, as shown in FIG. 12, the bolt B is inserted from the end of the accommodation groove 34 of the rafter 30, and the tip of the shaft portion of the bolt B is placed between the locking portions 35, 35. In a state of projecting from the gap, it is moved along the longitudinal direction of the groove to a desired position (a position between the solar panels 2 and 2 at a position where the solar panel 2 is fixed).

  The second energizing member 85 is attached to the shaft portion of the bolt B protruding from the rafter 30, and the shaft portion of the bolt B is inserted into the bolt through hole 86. At this time, the second energization member 85 is rotated as appropriate, and the number of first energization protrusions 87 positioned in the gap between the locking portions 35 and 35 and the gap between the solar panels 2 and 2 to be installed thereafter. It is preferable to install so that the number of the second energizing protrusions 88 located in the space is reduced.

  Thereafter, the solar panel 2 is installed on the second energizing member 85. Two solar panels 2 are arranged above and below in the tilt direction with the shaft portion of the bolt B and the pressing member 90 interposed therebetween. At this time, the shaft portion of the bolt B is inserted into the bolt through hole 93 of the pressing member 90. The pressing member 90 is spanned between the solar panels 2 and 2. The two solar panels 2 are arranged with a gap in order to arrange the bolt B and the pressing member 90.

  Thereafter, the nut N is attached to the tip of the shaft portion of the bolt B protruding from the pressing member 90 and tightened. At this time, since the head of the bolt B is in a state in which the rotation is blocked by the accommodation groove 34 of the rafter 30, the nut N can be easily tightened. By this tightening, the bolt B and the nut N clamp and clamp the locking portion 35, the second energizing member 85, and the pressing member 90. Thereby, the pressing member 90 presses the solar panel 2, the solar panel 2 is pressed against the second energizing member 85, and the second energizing member 85 is sandwiched between the solar panel 2 and the locking portion 35. The Rukoto. At the same time, the first plate portion 92a (insertion plate portion 92) of the pressing member 90 contacts the upper edge end surface 2a of the lower solar panel 2, and the second plate portion 92b (insertion plate portion 92) is on the upper side. The solar panel 2 comes into contact with the lower edge 2b.

  The solar panel 2 is fixed by being locked to the pressing member 90 at both upper and lower ends in the tilt direction (only one is shown in FIG. 11).

  According to such a fixing structure, since the first energizing protrusion 87 of the second energizing member 85 bites into the outer surface of the locking portion 35, it penetrates the corrosion-resistant coating layer on the surface of the locking portion 35. Thereby, the electrical conductivity of the 2nd electricity supply member 85 and the rafter 30 is ensured. Furthermore, since the second energizing protrusion 88 of the second energizing member 85 bites into the lower end of the lower surface of the solar panel 2, it penetrates the corrosion-resistant coating layer on the surface of the solar panel 2. Thereby, the electrical conductivity of the 2nd electricity supply member 85 and the solar panel 2 is ensured. That is, according to this fixing structure, the conductivity of the rafter 30 and the solar panel 2 can be ensured via the second energization member 85, so that the solar panel 2 can be prevented from being charged, and the operator can There is no problem even if the solar panel 2 or the frame material of the solar panel mount 1 is touched. In addition, the electric current which flowed into the solar panel 2, the rafter 30, and the rafter receiver 10 is flowed to the ground via the earth | ground installed in the fastener member (not shown) which fixes the support | pillar 40 and the pile 41.

  In addition, in the second energization member 85, the following operational effects can be obtained in addition to the operational effects obtained in the first energization member 80. In the second energizing member 85, the first energizing protrusion 87 and the second energizing protrusion 88 are triangular not only in cross-sectional shape but also in plan view, and therefore compared with the energizing protrusions 82 and 83 of the first energizing member 80. Thus, pressing can be performed with a small pressure. Furthermore, the first energizing protrusion 87 and the second energizing protrusion 88 of the second energizing member 85 are likely to bite into other members.

  Furthermore, according to the 1st electricity supply member 80 and the 2nd electricity supply member 85, since it has the 1st electricity supply protrusions 82 and 87 and the 2nd electricity supply protrusions 83 and 88 which bite into the member to contact | abut, The sliding of the rafters 30 or the members of the rafters 30 and the rafter frame 10 can also be suppressed.

  As mentioned above, although the form for implementing this invention was demonstrated, this invention is not limited to the said embodiment, In the range which does not deviate from the meaning of this invention, a design change is possible suitably. For example, in the present embodiment, the member fixing structure is employed for fixing the rafter receiver 10 and the rafter 30 and fixing the rafter 30 and the solar panel 2, but an accommodation groove is formed in one of the other members. For example, it can be used to fix other members. Furthermore, it is employable also as a fixing structure of members other than a solar panel mount.

  Moreover, in the said embodiment, although the 2nd electricity supply member 85 is exhibiting the shape where each side of the regular dodecagon was notched in the V shape inside, it is not limited to this. For example, as shown in FIG. 16 (a), each of the regular octagonal sides may be a current-carrying member 85a in which each side is cut out in a V shape, or as shown in FIG. 16 (b). Alternatively, the energizing member 85b may be a shape in which each side of the regular decagon is cut out in a V shape inside. In each of the energization members 85a and 85b, the protruding corners are perpendicular to each other. The protruding corner is not limited to a right angle, and may be an acute angle or an obtuse angle. In the energizing members 85a and 85b, the first energizing protrusions 87 and the second energizing protrusions 88 are alternately formed at adjacent protruding corners. Further, both of the energization members 85a and 85b are formed with bolt through holes 86 at the center of gravity of the metal plate material.

  Thus, the following effects are obtained by changing the number of protruding corners. When the number of projecting corners is increased, the first energizing protrusion 87 and the second energizing protrusion 88 are increased, so that the conductivity can be improved. On the other hand, when the projecting corners are reduced, the first energizing protrusions 87 and the second energizing protrusions 88 are reduced, so that the processing effort can be reduced.
