And in patent document 1, the foundation pile is formed of the square steel pipe.

Japanese Patent Laying-Open No. 2012-69929 (paragraphs 0026 and 0027, FIG. 1)

  When the foundation pile of the solar panel pedestal is formed of a rod-shaped steel pipe having a hollow inside, such as a square steel pipe or a round steel pipe as described above, Because it becomes a non-contact surface that does not contact the soil, it is not possible to expect a large pulling resistance of the foundation pile from the ground.

  An object of the present invention is to provide a platform for a solar panel that can cause a large pulling resistance from the ground to a foundation pile.

  The solar panel gantry according to the present invention includes a foundation frame for arranging the solar panel, a foundation pile supporting the foundation frame with a head, and leaving the head on the ground and entering the ground. In this case, the foundation pile is connected to the first side portion in which the width direction is a horizontal direction and the first side portion at an angle, and the width direction Is formed of a rod-like material having a second side portion that is in a horizontal direction, and both the front and back surfaces of the first side portion and the front and back surfaces of the second side portion are in contact with the soil of the ground. It is characterized by being a surface.

  In the present invention, the foundation pile is connected to the first side portion in which the width direction is the horizontal direction and the first side portion at an angle, and the second side in which the width direction is the horizontal direction. And the front and back surfaces of the first side and the front and back surfaces of the second side are contact surfaces that come into contact with the soil of the ground. The contact area between the foundation pile and the soil of the ground can be made larger than the rod-shaped material such as square steel and round steel, which can cause a large pulling resistance from the ground to the foundation pile. Become.

  In this invention, the shape of the front part which has penetrate | invaded the inside of the ground in a foundation pile is a flat surface where the front end surface is horizontal or substantially horizontal, and the whole 1st side part and 2nd side part However, it is preferable that the shape of the tip is a tapered shape in which the horizontal width dimension gradually decreases downward.

  According to this, when the tip of the foundation pile is infiltrated into the ground by a device such as a pile driving machine, the resistance force acting on the foundation pile from the ground can be reduced, so the tip of the foundation pile is placed inside the ground. Work to invade can be easily performed.

  And the above-mentioned taper shape may be the shape in which the connection part of the 1st side part and the 2nd side part is left in the front end surface of a foundation pile, or the 1st side part in the front end surface of a foundation pile And the second side portion may have a shape in which at least a part of one side remains and the other does not remain.

  According to the former, since the connection part of the 1st side part and the 2nd side part remains in the front end surface of a foundation pile, this front end surface is at least a part of the 1st side part, and at least a 2nd side part. Because the strength of the tip of the foundation pile can be increased by the first side and the second side that are connected at an angle, the pile driving machine, etc. It is possible to prevent the tip portion from being deformed when the tip portion of the foundation pile is intruded into the ground by the device.

  Note that, as described above, the tapered shape is a shape in which the connecting portion between the first side and the second side is left on the front end surface of the foundation pile. And the second side part may be formed by one whole and the other part, or may be formed by a part of the first side part and a part of the second side part. Good.

  In addition, when the above-mentioned tapered shape is a shape in which at least a part of one of the first side part and the second side part remains and the other does not remain in the tip surface of the foundation pile, When the tip of the foundation pile is infiltrated into the ground by a device such as a pile driver, the other side does not remain on the tip of the foundation pile, so the resistance force acting on the foundation pile from the ground is reduced accordingly. As a result, the load for allowing the foundation pile to enter the ground can be reduced.

  Moreover, in this invention, you may provide the slipping out resistance generation | occurrence | production part for producing the resistance with respect to slipping out of the foundation pile from this ground in the part which has penetrate | invaded the inside of the ground among the full length of a foundation pile.

  According to this, it becomes possible to give a greater pulling resistance from the ground to the foundation pile by the pull-out resistance generating portion.

  In this way, when a part of the total length of the foundation pile that has entered the ground is provided with a pull-out resistance generating part for generating resistance against the pull-out of the foundation pile from the ground, this pull-out The resistance generating part may be of any shape or structure, and the pulling out resistance generating part of the example has a shape inclined upward and downward with respect to the foundation pile.

  According to this, the slip-out resistance generation part is inclined in a diverging upward direction with respect to the foundation pile, so that when the foundation pile enters the ground, the slip-out resistance generation part has a large resistance at the time of this intrusion. When the foundation pile is about to come out of the ground, it will not be a force generating part, but the pulling out resistance generating part becomes a large resistance generating part, so it is effective to pull out the foundation pile from the inside of the ground. Can be prevented.

  Such a slip-out resistance generating part can be provided in the foundation pile in an arbitrary form, and an example thereof is to cut out and process a part of the foundation pile to form a slip-out resistance generating part in the foundation pile. In addition, another example is to provide a slip-out resistance generating portion on the foundation pile by connecting the slip-out resistance generating member to the foundation pile.

  And such a slipping out resistance generating part may be one in which at least a part protrudes outside the space part with the first side part and the second side part as a part of the outer contour in the foundation pile. In addition, it is preferable to provide the foundation pile with a resistance generating portion that is pulled out while being housed inside such a space.

  According to this, for example, when the foundation pile is transported from the factory to the installation site of the solar panel mount, or when the foundation pile is handled at this installation site, the pull-out resistance generating portion is the first side portion and the second side portion. Since it is in the state accommodated in the space part which uses as a part of outer contour, the conveyance work and handling work of a foundation pile can be performed easily.

  Further, in the present invention, in the middle of the length direction of the foundation pile, in the portion corresponding to the position of the surface of the ground, the penetration resistance force for generating the resistance force against the penetration of the foundation pile into the ground It is preferable to provide a generation part.

  According to this, when an operation such as a pile driving machine is used to infiltrate the foundation pile into the ground, if the foundation pile enters the ground to a predetermined depth, the invasion resistance generating part causes the foundation pile to Since resistance against intrusion into the ground is generated, the depth for allowing the foundation pile to enter the ground can be set accurately and automatically.

  In addition, an invasion resistance generation part can be easily provided in a foundation pile by forming such an invasion resistance generation part by the horizontal or substantially horizontal plate-shaped member couple | bonded with the foundation pile.

  The foundation pile according to the present invention described above is connected to the first side portion whose width direction is the horizontal direction and the first side portion at an angle, and the width direction is the horizontal direction. As long as it is formed of a rod-shaped material having the second side portion, any material or steel material may be used, and this foundation pile may be formed of, for example, channel steel, or formed of channel steel with a lip. Alternatively, it may be formed of H-shaped steel, I-shaped steel, L-shaped steel, or Z-shaped steel.

  Further, in the present invention, the foundation frame on which the solar panel is arranged is supported by the head of the foundation pile exposed on the ground, but the foundation frame may be directly supported by this head, or A connecting member such as an intermediate member having a small vertical dimension or a column member having a large vertical dimension may be connected to the head, and the foundation frame may be supported by the head of the foundation pile via the connecting member.

  Further, in the present invention, the solar panel and the base frame are installed on the ground inclined with respect to the horizontal direction, but the number of foundation piles arranged in the inclined direction may be one, and a plurality It may be a book.

  According to the present invention, it is possible to obtain an effect that a large pulling resistance from the ground can be generated in the foundation pile.

  As shown in FIG. 3, the end portion on the foundation pile 3 side of the above-mentioned wand member 7 formed of channel steel (channel material) is coupled to the foundation pile 3 by a coupling means 60. The coupling means 60 includes a first member 61 and a second member 62 which are band-shaped members facing each other in the left-right direction. The first member 61 is formed with a size corresponding to the left-right dimension and the front-rear dimension of the foundation pile 3, and is formed with a recess 61A that can accommodate the entire left-right direction and the front-rear direction of the foundation pile 3 inside. In front of and behind the recess 61A, tongue pieces 61B and 61C are provided in parallel with the second member 62, which is a flat plate-shaped member. The second member 62 has a length in the front-rear direction that is longer than that of the first member 61, and the two holes 63 formed in the second member 62 at an interval larger than the front-rear dimension of the foundation pile 3, 64 and holes 65 and 66 provided in the tongue pieces 61B and 61C of the first member 61, bolts 67 and 68 are inserted, and nuts 69 and 70 are screwed into the ends of these bolts 67 and 68, respectively. By tightening, the first member 61 and the second member 62 are in a state where the foundation pile 3 is housed in the recess 61 </ b> A of the first member 61, in other words, the first member 61 and the second member 62 of the foundation pile 3. It is combined with the foundation pile 3 in a state of surrounding the periphery.

  The second member 62 has a hole 71 formed in front of the hole 63, and a bolt 72 is inserted into the hole 71 and a hole provided at the end of the cane member 7 on the foundation pile 3 side. Then, the nut 73 is screwed onto the end portion of the bolt 72 and tightened, whereby the end portion on the foundation pile 3 side of the cane member 7 is the second member 62 that is a constituent member of the coupling means 60 described above. It couple | bonds with the foundation pile 3 via. Further, as can be seen from FIG. 2, a hole into which a bolt 74 is inserted is formed at the end of the cane member 7 on the base frame 1 side, and this bolt 74 is formed on the web of the aforementioned large pulling member 4. The end portion on the base frame 1 side of the wand member 7 becomes a constituent member of the base frame 1 by being inserted into a hole provided in the portion 22 and screwing and tightening a nut to the end portion of the bolt 74. The large pulling member 4 is coupled.

  Thereby, even if each large pulling member 4 which comprises the base frame 1 is couple | bonded with the connection member 6 couple | bonded with the head of each foundation pile 3 with the one volt | bolt 25, foundation pile 3 The base frame 1 composed of the large pulling member 4 and the joist member 5 is supported on the foundation pile 3 by tilting the front-rear direction at a predetermined angle with respect to the horizontal direction by the support action of the cane member 7 provided for each. Can be made.

  FIG. 4 shows a plan view of the base frame 1 composed of the large pulling member 4 and the joist member 5. A plurality of solar panels SP are arranged on the base frame 1. In the illustrated example, seven solar panels SP are arranged in the left-right direction and two in the front-rear direction. The solar panel SP is placed on the upper surface of the first flange portion 31 of each of the first short dimension member 5A, the long dimension member 5B, the second short dimension member 5C, and the third short dimension member 5D of the joist member 5. Holes 8 are formed in the first flange portions 31 of the long dimension member 5B, the second short dimension member 5C, and the third short dimension member 5D, and bolts inserted into these holes 8 The solar panel SP is fixed to the base frame 1.

  The operations for connecting the large pulling member 4 which is a constituent member of the foundation frame 1 to the heads of the respective foundation piles 3 through the connecting members 6 as described above are performed by connecting the respective foundation piles 3 to these foundation piles. This is performed after the work of leaving the head of 3 on the ground and entering the ground 2 with a device such as a pile driver.

  In this way, when the work of leaving each head pile 3 in the ground 2 with the head remaining on the ground is performed, the foundation pile 3 having an error in the penetration depth among the plurality of foundation piles 3 Even if it occurs, this error can be eliminated for the foundation pile 3 by the long hole 14 formed long in the vertical direction in the connecting member 6 described in FIG. Moreover, about the foundation pile 3 from which the position penetrate | invaded into the ground 2 has shifted | deviated to the front-back direction rather than the predetermined position, this shift | offset | difference can be eliminated with the long hole 18 formed in the connection member 6 long in the front-back direction. . Further, for the foundation pile 3 whose position to enter the ground 2 is shifted in the left-right direction from the predetermined position, the long hole 48 formed long in the left-right direction in the first short dimension member 5A of the joist member 5 The deviation can be eliminated.

  In addition, when the posture that intrudes into the ground 2 is not a vertical posture and the foundation pile 3 that inclines in the front-rear direction with respect to the vertical direction and enters the inside of the ground 2 is generated, the cane member 7 The vertical height position of the coupling means 60 that couples the end of the foundation pile 3 to the foundation pile 3 is adjusted. That is, the coupling means 60 according to the present embodiment is configured to include the first member 61 and the second member 62 surrounding the foundation pile 3 as described with reference to FIG. Since the second member 62 can be selected from the coupled state and the uncoupled state with respect to the foundation pile 3 by the bolts 67 and 68 and the nuts 69 and 70, the second member 62 can be selected in the foundation pile 3 by loosening the bolts 67 and 68. The vertical height positions of the first member 61 and the second member 62 can be changed.

  By performing this change work, the end portion on the foundation pile 3 side is rotatably coupled to the coupling means 60 with one bolt 72, and the end portion on the base frame 1 side is also large with one bolt 74. Since the inclination angle with respect to the horizontal direction of the wand member 7 that is rotatably coupled to the pulling member 4 changes, the foundation pile 3 in which the posture entering the ground 2 is inclined in the front-rear direction with respect to the vertical direction. Even if this occurs, the base frame 1 can be supported by the heads of the respective foundation piles 3 with the longitudinal direction of the base frame 1 being set at a predetermined inclination angle with respect to the horizontal direction.

  And changing the inclination angle with respect to the horizontal direction of the cane member 7 in this way is when an error has occurred in the penetration depth of the foundation pile 3 into the ground 2 or when the foundation pile 3 is moved to the ground 2. Even when the position of intrusion into the interior is shifted in the front-rear direction from the predetermined position, the base frame 1 is set so that the front-rear direction of the base frame 1 is set at a predetermined inclination angle with respect to the horizontal direction. It can be used as an effective means for supporting the head.

  In this embodiment, as shown in FIG. 4 and the like, the number of foundation piles 3 arranged in the left-right direction is three, but this number can be four or more. Thus, when the number of the foundation piles 3 is four or more, the first short of the joist members 5 arranged on the large pulling members 4 of the two or more foundation piles 3 excluding the foundation piles 3 arranged on the left and right ends. A long dimension member 5B is connected to the left and right ends of the dimension member 5A, and a second short dimension member 5C is connected to the right end of the first short dimension member 5A of the joist member 5 disposed on the large pulling member 4 of the foundation pile 3 at the right end. And the third short dimension member 5D may be coupled to the left end portion of the first short dimension member 5A of the joist member 5 disposed on the large pulling member 4 of the leftmost foundation pile 3.

  As can be seen from this description, according to the solar panel mount according to the present embodiment, the joist member 5 on which the solar panel SP is placed includes the first short dimension member 5A, the long dimension member 5B, and the second short dimension. Since it is constituted by the member 5C and the third short dimension member 5D, the number of the foundation pile 3 and the long dimension member 5B, the connecting member 6 coupled to the foundation pile 3, and the large pulling member 4 In other words, by simply increasing the number of the cane members 7, in other words, without adding another kind of member, the size of the solar panel mount can be increased in the left-right direction and is required to be arranged. Since the solar panel mount with any left and right dimensions corresponding to the number of solar panels can be manufactured, the solar panel mount according to this embodiment is applied to a mega solar system for large-scale power generation. Rukoto can.

  Moreover, since the first short dimension member 5A, the long dimension member 5B, the second short dimension member 5C, and the third short dimension member 5D are made of Z-shaped steel, the platform for a solar panel having a large lateral dimension is provided. When these are manufactured, these members 5A to 5D can be connected to each other by overlapping the top and bottom with a small vertical step.

  FIG. 5 shows a tip portion that enters the ground 2 in the foundation pile 3. The shape of the tip portion is a tapered shape in which the horizontal width dimension gradually decreases downward. Specifically, the tip portion of the foundation pile 3 is the second of the first flange portion 11, the web portion 12, and the second flange portion 13 that form the foundation pile 3. It is formed by cutting obliquely downward from the flange portion 13 toward the first flange portion 11. The lower end of this cutting does not reach the first flange portion 11. For this reason, the connection part 75 of the 1st flange part 11 and a part of web part 12 which has made a right angle with this 1st flange part 11 remains in the front end surface of the foundation pile 3, and the front part Is formed by the entire first flange portion 11 and a part of the web portion 12.

  As described above, when the foundation pile 3 is operated to leave the head on the ground and enter the ground 2 with an apparatus such as a pile driving machine, the both sides of the first flange portion 11 and the web portion 12 The foundation pile 3 penetrates into the ground 2 while both the front and back surfaces and the front and back surfaces of the second flange portion 13 are in contact with the soil of the ground 2. For this reason, the contact area between the foundation pile 3 and the soil of the ground 2 is larger than that of a rod-shaped material such as square steel or round steel whose left and right dimensions and front and rear dimensions are the same as those of the foundation pile 3. Thus, a large pulling resistance from the ground 2 can be generated in the foundation pile 3.

  In addition, the shape of the tip of the foundation pile 3 is a tapered shape in which the horizontal width dimension gradually decreases downward, so that the foundation pile 3 is not in the ground 2 when the foundation pile 3 enters the ground 2. The resistance force received from the soil is reduced, and thereby, the work of invading the ground 2 of the foundation pile 3 (the work of driving the foundation pile 3) can be easily performed.

  Furthermore, since the connection part 75 with the 1st flange part 11 and a part of web part 12 which makes a right angle with this 1st flange part 11 is provided in the front end surface of the foundation pile 3, this front end surface is attached. The strength of the tip portion of the foundation pile 3 is greater than that formed only by the first flange portion 11, so that the tip portion of the foundation pile 3 is brought into the ground 2 by a device such as a pile driving machine. It is possible to perform the intruding operation while suppressing the deformation of the tip.

  In this embodiment, as shown in FIG. 1 and FIG. 2, the foundation pile 3 is located in the middle of the foundation pile 3 in the length direction and corresponding to the position of the surface 2 </ b> A of the ground 2.
