In this solar panel gantry, simplification of the whole gantry and simplification of construction are achieved by forming a support frame.

JP 2009-290107 A

  However, in the solar panel mount, since the support frame and each support column are connected by one bolt, the bending stress applied to the mounting beam is large, and the plate thickness of each mounting beam is increased. There has been a problem in that the weight of the frame and by extension, the entire gantry is increased.

  From such a viewpoint, this invention makes it a subject to provide the solar panel mount which can achieve weight reduction.

The invention according to claim 1 for solving such a problem includes a solar panel mount for fixing a solar panel, a plurality of rafters whose longitudinal direction is inclined with respect to the horizontal direction, and the longitudinal direction being horizontal. A pair of rafter receiving frames that intersect with the rafters and a plurality of supporting columns that support the rafter receiving frames, and two or more supporting columns are provided for each rafter receiving frame, The receiving frame and the support column are connected via a gusset plate, and the surface of the rafter receiving frame to which the gusset plate is connected and the surface of the support column to which the gusset plate is connected are in the same plane. The gusset plate has a long rectangular shape along a longitudinal direction of the rafter receiving frame, and the rafter of the gusset plate A surface in contact with only the frame, the surface in contact with said post is a solar panel frame, characterized in that are flush with each other.

  According to such a configuration, the rafter receiving frame is reinforced in the section where the gusset plate is disposed, and the deflection at the center of the span is reduced. Specifically, since the substantial distance between the supporting points of the rafter receiving frame can be shortened, the bending moment applied to the rafter receiving frame can be reduced, and the bending at the center of the span can be reduced. As a result, the rafter receiving frame can be formed thin, so that the weight can be reduced, and as a result, the entire solar panel mount can be reduced in weight.

  According to a second aspect of the present invention, the gusset plate is provided with ridges or grooves, and the rafter receiving frame has grooves or ridges that mesh with the ridges or grooves provided on the gusset plate. It is provided.

  According to such a configuration, it is possible to easily position the engagement position between the gusset plate and the rafter receiving frame.

  The invention according to claim 3 is characterized in that the gusset plate has a length in a range of 0.075 to 0.150 times the total length of the rafter receiving frame.

  If the gusset plate is shorter than 0.075 times the total length of the rafter, the effect of reducing the bending moment may be sufficiently reduced. If the gusset plate is longer than 0.150 times, the weight of the gusset plate increases, Although the effect of reducing the weight may be reduced, if the length of the gusset plate is 0.075 to 0.150 times the total length of the rafter receiving frame, the bending moment can be reduced. While increasing the weight of the gusset plate, it can be suppressed.

  According to a fourth aspect of the present invention, the rafter receiving frame is stretched over the support so that both ends of the rafter receiving frame protrude from the gusset plate, and the protruding length of the rafter receiving frame is equal to that of the rafter receiving frame. The length is in the range of 0.085 to 0.410 times the total length.

  According to such a configuration, the bending moment applied near the center of the span of the rafter receiving frame can be reduced as compared with the case of a simple beam that does not project both ends of the rafter receiving frame. The cross-sectional area can be reduced, and as a result, the weight of the rafter receiving frame can be reduced. If the ratio of the overhang length is smaller than 0.085 or larger than 0.410, the reduction rate of the maximum bending moment applied to the rafter receiving frame will be 1/3 or less, so the effect of weight reduction is not so much. I can't get it.

  The invention according to claim 5 is characterized in that a brace is provided between the column supporting one of the rafter receiving frames and the column supporting the other rafter receiving frame.

  The invention according to claim 6 is characterized in that a brace is provided between the columns supporting one of the rafter receiving frames.

  The invention according to claim 7 is characterized in that a brace is provided between the columns supporting the other rafter receiving frame.

  According to such a configuration, a brace is provided between two adjacent struts, so that the structure does not easily fall down.

According to an eighth aspect of the present invention, the support column has a quadrangular prism shape, and a bolt head or the support column for fixing the support column and the gusset plate is provided on each of the four side surfaces of the support column. A receiving groove for receiving the head of a bolt for fixing the brace is formed extending in the longitudinal direction of the support column, and the receiving groove extends inward from the groove side walls on both sides. A pair of locking portions are formed.

  According to such a structure, since a bolt can be installed in each side of a support | pillar, various members can be easily fixed to a support | pillar.

  The invention according to claim 9 is characterized in that the rafter, the rafter receiving frame, the support column, and the gusset plate are all made of an extruded shape made of an aluminum alloy.

  According to such a configuration, the solar panel gantry can be reduced in weight, and the gantry can be a highly accurate gantry, and further excellent weather resistance and aesthetics can be obtained.

  According to the solar panel mount according to the present invention, weight reduction can be achieved.

The head of the bolt B is inserted from the end in the longitudinal direction of the side receiving groove 11b. The bolt B is moved to a desired position along the longitudinal direction of the groove with the shaft portion protruding from the gap between the locking portions 13 and 13. The locking portion 13 is in contact with the seating surface of the head of the bolt B and prevents the bolt B from falling out of the receiving groove 11.

  A concave groove 16 extending in the longitudinal direction is formed on the side surface of the rafter receiver 10. The concave groove 16 is formed below the side accommodating groove 11b. The concave groove 16 is a portion that meshes with a ridge 82 of a gusset plate 80 described later.

  As shown in FIGS. 4 and 5, the rafter receiver 10 and the support column 40 are connected via a gusset plate 80. At the connecting portion between the rafter receiver 10 and the support column 40, the upper end surface of the support column 40 is in contact with the lower surface of the rafter receiver 10, and the rafter receiver 10 and the support column 40 are sandwiched between a pair of gusset plates 80 and 80. Yes.

  The gusset plate 80 has a rectangular shape in a side view, and its longitudinal dimension is longer than that of a general gusset plate. The gusset plate 80 is made of an extruded shape made of an aluminum alloy. The gusset plate 80 is disposed such that the longitudinal direction (extrusion direction) is along the longitudinal direction of the rafter receiver 10. Reinforcing ribs 81 are formed on both upper and lower edges of the gusset plate 80, respectively. The reinforcing rib 81 is bent outward (outside when the rafter receiver 10 is sandwiched) with respect to the plate portion of the gusset plate 80. Bolt through holes (not shown) are appropriately formed in the gusset plate 80. The shaft portion of the bolt B is inserted into the bolt through hole.

  As shown in FIG. 5, a ridge 82 is formed on the surface of the gusset plate 80 that contacts the rafter receiver 10. The ridges 82 extend along the longitudinal direction of the gusset plate 80. The ridge 82 serves to position the gusset plate 80 and the rafter receiver 10 by being fitted in the groove 16 of the rafter receiver 10. In this embodiment, the ridge 82 is formed on the gusset plate 80 and the concave groove 16 is formed on the rafter receiver 10. However, the concave groove 16 is formed on the gusset plate 80 and the convex stripe is formed on the rafter receiver 10. May be.

  At the connecting portion between the rafter receiver 10 and the gusset plate 80, the head of the bolt B is received in the side receiving groove 11b of the rafter receiver 10, and the shaft portion of the bolt B protrudes from the side receiving groove 11b. The shaft portion that protrudes from the side accommodating groove 11 b passes through the bolt through hole of the gusset plate 80 and also protrudes from the gusset plate 80. When the nut N is tightened on the shaft portion of the bolt B protruding from the gusset plate 80, the locking portion 13 of the side housing groove 11b and the gusset plate 80 are sandwiched between the head portion of the bolt B and the nut N. As a result, the rafter receiver 10 and the gusset plate 80 are fixed.

In the connecting portion between the support column 40 and the gusset plate 80, the head of the bolt B is stored in the long-side storage groove 41a of the support column 40, and the shaft portion of the bolt B protrudes from the long-side storage groove 41a. . The shaft portion that protrudes from the long side accommodation groove 41 a passes through the bolt through hole of the gusset plate 80 and also protrudes from the gusset plate 80. When the nut N is tightened on the shaft portion of the bolt B protruding from the gusset plate 80, the locking portion 43 of the long side accommodation groove 41 a and the gusset plate 80 are sandwiched between the head of the bolt B and the nut N. Thereby, the support column 40 and the gusset plate 80 are fixed.
Thereby, the rafter receiver 10 and the support column 40 are connected via the gusset plate 80.

  Below, the relationship between the length L (refer FIG. 4) of the gusset plate 80 and the weight of the rafter receptacle 10 and the gusset plate 80 is demonstrated. For example, it is assumed that the length of the rafter receiver 10 is 4000 mm and the weight of the rafter receiver 10 is 14 kg when it is joined to the support column 40 without using a gusset plate. Here, when the rafter receiver 10 and the support column 40 are connected using the gusset plate 80 having a length L of 200 mm, the substantial distance between the fulcrums of the rafter receiver 10 can be shortened. Since the bending moment can be reduced and the cross-sectional area of the rafter receiver 10 can be reduced, the weight of the rafter receiver 10 can be reduced to about 10 kg. The weight (for two sheets) of the gusset plate 80 is about 1 kg. Since the total weight of the rafter holder 10 and the gusset plate 80 is about 11 kg, the weight can be reduced by about 3 kg.

  In addition, when the length L of the gusset plate 80 was set to 350 mm, the weight of the rafter receiver 10 was about 7 kg, and the weight of the gusset plate 80 (for two sheets) was about 2 kg. Since the total weight of the rafter holder 10 and the gusset plate 80 is about 9 kg, the weight can be reduced by about 5 kg.

  That is, if the gusset plate 80 is lengthened, the rafter receiver 10 can be reduced in weight. However, the weight of the gusset plate 80 increases as the gusset plate 80 is lengthened. Therefore, the range of the length L of the gusset plate 80 is preferably set in consideration of the balance between the weight reduction effect of the rafter receiver 10 due to the lengthening of the gusset plate 80 and the amount of increase in the weight of the gusset plate 80. . In consideration of the above, when the rafter receiver 10 is 4000 mm, the length L of the gusset plate 80 is preferably set to 300 mm to 600 mm. As a result, the length L of the gusset plate 80 is in the range of 0.075 to 0.150 times the total length Y of the rafter receiver 10. More preferably, the length L of the gusset plate 80 is 350 mm to 500 mm. According to this, the length L of the gusset plate 80 is in the range of 0.088 (0.0875) to 0.125 times the total length Y of the rafter receiver 10.

  As shown in FIG. 1, both end portions of the rafter receiver 10 supported by the pair of struts 40, 40 protrude outward from the struts 40, 40 on both sides at equal distances. The overhang length X of the rafter receiver 10 is 0.210 times the total length Y of the rafter receiver 10. Below, the basis of the numerical value of the overhang length X will be described. The stress generated in the rafter receiver 10 in the basic design of the gantry is determined by the positions of the two struts (support points) 40 and 40. In the following examination of the overhang length X, calculation is performed on the assumption that an evenly distributed load acts on the beam (rafter receptacle).

Normally, when a uniformly distributed load w is applied over the entire length of the beam, the bending moment generated in the beam is maximized when the beam is supported at both ends, that is, when the beam overhang length X is zero. It is. The bending moment (maximum bending moment) M at the center of the horizontal joist at this time is
M = w · ^l 2/8
w: Uniform load 1: Distance between fulcrums.

On the other hand, the bending moment occurring in the beam is minimized, is when the bending moment M _A of the central portion of the bending moment M _X and the beam of the overhang portion of the both end portions of the beam are equal. Here, ^M _X = -wX 2/2
M _A = [{w (X + l) ² −wX ² } / 2l] · l / 2−w / 2 (X + l / 2) ²
Although it represented as a uniformly distributed load w of the solar panel 2, and set to be a general number 9.8 N (1 _kgf), the overhanging length X of the transverse joists satisfying M X = _{M A} When calculated, the total length Y of the rafter receiver 10 is 0.210 times.

Incidentally, in the present invention, and to limit the bending moment occurring in the rafter receiving 10, the maximum bending moment ^{M 2/3 (= w · l 2} /12) within. When the overhang length X of the lateral joist satisfying this upper limit is calculated, the length is in the range of 0.085 to 0.410 times the total length Y of the rafter receiver 10.

The locking portions 13 and 13 are inclined at the same inclination angle with respect to the horizontal direction, and are formed in the same plane. These locking portions 13, 13 constitute an inclined upper end surface of the rafter receiver 10.

  The locking portions 13 and 13 are engaged with the first reinforcing member 50 to prevent the first reinforcing member 50 from falling out of the upper housing groove 11a. The gap between the locking portions 13 and 13 is the shaft portion of the bolt B and its peripheral portion (the thick portion sandwiched between the two rows of guide grooves 54 and 54 in the substrate portion 51 of the first reinforcing member 50). It has a width dimension that can be inserted. A protrusion 14 for guiding the movement of the first reinforcing member 50 (hereinafter sometimes referred to as “guide protrusion 14”) is formed in the locking portion 13. The guide protrusion 14 is formed over the entire length in the longitudinal direction of the upper receiving groove 11a. The guide protrusion 14 protrudes from the front end (inner end) in the width direction of the locking portion 13 into the groove.

  As shown in FIG. 9, the rafter 30 is made of an aluminum alloy hollow extruded profile. The rafter 30 includes a web portion 31 and flange portions 32, 32... Formed above and below the web portion 31. In addition, when the flange part 32 is distinguished by the upper flange part 32 and the lower flange part 32, it may be called "upper flange part 32b" and "lower flange part 32a".

  The cross-sectional shape of the web part 31 has a hollow trapezoidal shape with the lower side widened. An accommodation groove 34 is formed at the upper end of the web portion 31. A head of a bolt (not shown) for fixing the solar panel 2 (see FIG. 3) is inserted into the housing groove 34. A pair of locking portions 35, 35 extending inward from the groove sidewalls on both sides are formed at the upper opening end of the receiving groove 34.

  The upper flange portions 32b and 32b are provided so as to extend from the upper end of the web portion 31 in both outward directions (both sides in the thickness direction of the web portion 31). The lower flange portions 32 a and 32 a are provided so as to extend from the lower end of the web portion 31 in both outward directions (both sides in the thickness direction of the web portion 31). The lower flange portion 32 a constitutes a locking plate piece that is pressed by the second reinforcing member 70. Hereinafter, the lower flange portion 32a is referred to as a locking plate piece 32a. A rising portion 33 that rises upward is formed at the front end (outer end) in the width direction of the locking plate piece 32a.

  As shown in FIGS. 8 and 10, the first reinforcing member 50 is made of an extruded shape made of an aluminum alloy. 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 upper accommodation groove 11 a, 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. Two bolt through holes 53, 53 are formed in the substrate portion 51 at intervals in the extrusion direction. 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. When the bolts B and nuts N are tightened, the upper surface of the substrate portion 51 is pressed against the lower surface of the locking portion 13 to generate a frictional force. 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. The shaft portions of a pair of bolts B, B adjacent to each other along the longitudinal direction of the groove are inserted into the bolt through holes 53, 53.

  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.

  A pair of anti-rotation protrusions 56 a and 56 b for preventing the bolt B from rotating is formed on the lower surface of the substrate portion 51. The rotation preventing protrusions 56 a and 56 b are formed along the longitudinal direction of the first reinforcing member 50. The internal dimension between the pair of anti-rotation protrusions 56a and 56b is larger than the width of the two surfaces of the head of the bolt B and smaller than the diagonal distance. Accordingly, the bolt B is prevented from rotating while the head can be inserted between the bolt rotation preventing protrusions 56a and 56b. The bolt rotation preventing protrusions 56a and 56b have a protruding dimension shorter than the thickness dimension of the head of the bolt B. The bolt rotation prevention protrusion 56b on the side close to the temporary fixing wall portion 52 has a shorter projecting dimension than the bolt rotation prevention protrusion 56b on the far side so as not to interfere with a temporary fixing screw Va described later. Yes.

  The temporary fixing wall portion 52 is provided at one end of the substrate portion 51 in the width direction. When arrange | positioning the 1st reinforcement member 50 in the upper accommodating groove 11a, it arrange | positions so that the wall part 52 for temporary fixing may become an upper side. The temporary fixing wall portion 52 hangs down from the upper end of the substrate portion 51 along the groove sidewall 12b and intersects the substrate portion 51 at an acute angle. When the first reinforcing member 50 is housed in the upper housing groove 11a, the outer surface of the temporary fixing wall 52 and the groove side wall 12b come into contact with each other. Moreover, the hanging length of the temporary fixing wall portion 52 is set so that the lower end portion of the temporary fixing wall portion 52 comes into contact with the bottom portion of the upper receiving groove 11a. Note that the lower end portion of the temporary fixing wall portion 52 may not necessarily be in contact with the bottom portion of the upper receiving groove 11a, and may have a configuration in which a slight gap is provided between the lower end portion and the bottom portion of the upper receiving groove 11a. .

  A screw hole 55 is formed in the temporary fixing wall portion 52. A screw Va (see FIG. 8) for temporarily fixing the first reinforcing member 50 to the groove side wall 12b is inserted into the screw hole 55. The screw hole 55 is formed at one place in a substantially middle portion in the extrusion direction. The position of the screw hole 55 is not limited to the middle portion, and the number of the screw holes 55 is not limited to one. A screw hole 15 through which the screw Va is inserted is also formed in the groove side wall 12b. The screw hole 15 is formed at a position corresponding to the screw hole 55 when the first reinforcing member 50 is installed at the mounting position.

  As shown in FIG. 9, the first reinforcing member 50 is arranged so that its pushing direction is the same as the groove longitudinal direction of the upper receiving groove 11 a. The first reinforcing member 50 is formed to be longer than a normal washer so that a plurality of bolts B adjacent to each other along the groove longitudinal direction can pass therethrough. Specifically, the length dimension of the first reinforcing member 50 is set to be longer than the distance between the outer ends of the pair of second reinforcing members 70, 70 provided on both sides of the rafter 30.

  The second reinforcing member 70 is made of an extruded shape made of an aluminum alloy. The second reinforcing member 70 is arranged such that the extrusion direction is a direction (longitudinal direction of the rafter 30) perpendicular to the extrusion direction of the first reinforcement member 50. As shown also in FIG. 11, the 2nd reinforcement member 70 is provided with the board | substrate part 71 and the leg part 72, and the 2nd reinforcement member 70 is exhibiting L-shaped cross section. A bolt through hole 73 is formed at the center of the substrate portion 71. A shaft portion of the bolt B for fixing the rafter 30 to the rafter receiver 10 is inserted into the bolt through hole 73.

The leg portion 72 is formed to project downward from one end portion in the width direction of the substrate portion 71 (a direction orthogonal to the extrusion direction). The leg portion 72 is disposed on the side away from the rafter 30. The lower end portion of the leg portion 72 contacts the upper end surface of the rafter receiver 10 (the upper surface of the locking portion 13).
The side edge portion which is the other end portion in the width direction of the substrate portion 71 (the side in contact with the locking plate piece 32a of the rafter 30) constitutes a pressing portion 74 that holds and holds the end portion of the locking plate piece 32a. ing. On the lower surface of the pressing portion 74, a concave groove 75 into which the rising portion 33 formed at the front end portion in the width direction of the locking plate piece 32a is formed.

  As shown in FIG. 9, the second reinforcing members 70 are disposed at both ends in the width direction of the rafter 30. When the second reinforcing member 70 is tightened by the bolt B and the nut N, the locking plate piece 32 a of the rafter 30 is pressed and locked by the second reinforcing member 70. At the same time, the leg portion 72 of the second reinforcing member 70 is pressed against the locking portion 13 of the rafter receiver 10.

Below, the procedure which fixes the rafter receptacle 10 and the rafter 30 is demonstrated.
As shown in FIG. 8, 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 56a and 56b 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 of the upper receiving groove 11a, and the shaft portion of the bolt B is protruded from the gap between the locking portions 13 and 13 in a desired position ( It is moved along the longitudinal direction of the groove until the rafter 30 is fixed). At this time, since the first reinforcing member 50 is slightly smaller than the inner dimension of the upper receiving groove 11a, the first reinforcing member 50 is not caught on the inner surface of the upper receiving groove 11a. In addition, 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 upper accommodation groove 11a. Further, since the lower end portion of the temporary fixing wall portion 52 is in contact with the bottom portion of the upper receiving groove 11a, the first reinforcing member 50 is placed in the upper receiving groove with the inclination angle of the first reinforcing member 50 kept constant. It can be easily moved within 11a. 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.

  Next, at the construction site of the solar panel mount, the rafter receiver 10 is installed on the support column 40, and the rafter 30 is installed between the shafts of the bolts B and B protruding from the rafter receiver 10. The rafter 30 is arranged such that its longitudinal direction is orthogonal to the longitudinal direction of the rafter receiver 10, and is bridged between the pair of front and rear rafter receivers 10, 10. The rafter 30 is attached with a positioning screw Vb for determining the position of the rafter 30 relative to the rafter receiver 10 in the longitudinal direction. 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. The longitudinal position of the rafter 30 is easily determined by the head of the positioning screw Vb coming into contact with the corner of the upper end surface of the rafter receiver 10.

  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, and the locking plate piece 32a. And the leg part 72 of the 2nd reinforcement member 70 presses the latching | locking part 13 of the rafter receptacle 10, and the press part 74 presses and latches the edge part of the latching plate piece 32a. 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 solar panel mount 1 having the above configuration, the following operational effects can be obtained.
In the solar panel mount 1 according to the present embodiment, the rafter receiver 10 is connected to the support column 40 via the gusset plate 80, so that the rafter receiver 10 is reinforced in the section where the gusset plate 80 is disposed. Thus, the deflection at the center of the span is reduced. That is, since the substantial distance between the supporting points of the rafter receiver 10 can be shortened, the bending moment applied to the rafter receiver 10 can be reduced. Accordingly, the thickness of the rafter receiver 10 can be reduced and the cross-sectional area can be reduced, so that the rafter 10 can be reduced in weight.

  Furthermore, the length L of the gusset plate 80 is set to a length in the range of 0.075 to 0.150 times the total length Y of the rafter receiver 10, so that the effect of reducing the weight of the solar panel mount 1 is great. That is, if the gusset plate 80 is shorter than 0.075 times the total length Y of the rafter receiver 10, the bending moment cannot be sufficiently reduced. If it is longer than 0.150 times, the weight of the gusset plate 80 increases and the effect of reducing the weight of the entire gantry is reduced.

  Further, since the gusset plate 80 is provided with a ridge 82 and the rafter receiver 10 is provided with a concave groove 16 that meshes with the ridge 82, it is easy to position the mating position between the gusset plate 80 and the rafter receiver 10. And it can be done accurately. Further, since the ridges 82 and the grooves 16 serve as reinforcing ribs, the reinforcing effect of the gusset plate 80 and the rafter receiver 10 can be obtained.

  Since the rafter receiver 10 and the support column 40 are made of an extruded material made of aluminum alloy, the overall weight of the solar panel mount 1 can be reduced. Furthermore, the accuracy of each member can be increased, and the mounting operation can be performed easily and accurately, and excellent weather resistance and aesthetics can be obtained. In addition, since the aluminum alloy is excellent in recyclability, the material can be reused after the pedestal has deteriorated.

  On the other hand, according to the support column 40 of the present embodiment, the bolt B can be installed on each side surface, so that the brace 4 can be installed in any of the front, rear, left and right directions. Moreover, the installation height of the volt | bolt B can also be set freely. Furthermore, the braces 4 can be connected to a plurality of side surfaces as long as the braces 4 do not interfere with each other.

  Further, by projecting both ends of the rafter receiver 10 from the support column 40, the bending moment applied to the vicinity of the center of the span of the rafter receiver 10 can be reduced as compared with a simple beam supported at both ends. Therefore, compared to the case where the both ends of the lateral joists are not overhanged, the moment of inertia of the cross section of the rafter receiver 10 can be reduced, so that the thickness can be reduced and the cross sectional area can be reduced. Thereby, the rafter receiver 10 can be reduced in weight. In particular, when the overhang length X of the rafter receiver 10 is set to a length in the range of 0.085 to 0.410 times the total length Y of the rafter receiver 10, the bending moment applied to the rafter receiver 10 is the maximum bending moment. It is preferable that it is 2/3 or less. In particular, when the overhang length X of the rafter receiver 10 is 0.210 times the overall length Y of the rafter receiver 10, the bending moment applied to the rafter receiver 10 is minimized.

  In this way, by limiting the bending moment generated in the rafter receiver 10, the stress generated in the entire gantry can be reduced, and the solar panel gantry 1 having a light weight and sufficient strength can be provided.

  Moreover, in this embodiment, since the one rafter receptacle 10 is supported by the two support | pillars 40 and 40, it is stable. Furthermore, the brace 4 is provided between the struts 40, 40 adjacent in the vertical direction and between the struts 40, 40 adjacent in the horizontal direction, so that the structure is less likely to fall sideways. Moreover, since each rafter 10 and 10 is inclined with respect to the horizontal direction, the solar panel 2 can be opposed to the direction of the sun to perform efficient light reception.

On the other hand, according to the fixing structure of the rafter receiver 10 and the rafter 30 as described above, the following operational effects can be obtained.
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 upper receiving groove 11a. 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. .

  In addition, the first reinforcing member 50 is configured to pass through the shaft portions of a pair of bolts B and B adjacent in the upper housing groove 11a along the longitudinal direction of the groove. Since it is formed longer than the distance between the parts, the contact area of the first reinforcing member 50 to the locking part 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.

  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 rafter receiver 10, the rafter 30, and the support column 40 are made of an extruded shape made of an aluminum alloy, but the present invention is not limited to this. For example, you may form with other materials, such as stainless steel alloy, steel material, and resin material. Further, instead of the extruded shape, a plate material may be formed by bending.

  In the present embodiment, the rafter receiver 10 is supported by the two columns 40, but the present invention is not limited to this. For example, it may be supported by three or more struts, or may be supported by a V-shaped strut extending upwardly from one pile or foundation. When supporting with a V-shaped strut, provide a single pile (or foundation, etc.) below the longitudinal intermediate part of the rafter holder, and use two struts extending in a V-shape from the pile to the left and right The rafter holder may be supported, or two piles are provided below the longitudinal ends of the rafter holder, and two struts extending in a V shape from each pile to the left and right respectively (two struts in total) ) May support the rafter holder. When the rafter holder is long, a V-shaped support may be further provided.
