Description

  The present invention relates to a basic structure of a solar cell module or a solar cell array mount used in, for example, a solar power generation system.

  When laying a solar cell module or solar cell array used in a photovoltaic power generation system, for example, a concrete base is constructed by placing concrete in advance at a required location, and the base of the base is fixed to the concrete base. Is generally adopted.

  This prevents the platform (solar cell module or solar cell array) from floating from the ground due to wind pressure (wind load) acting on the solar cell module or solar cell array platform, and the weight of the solar cell module or solar cell array. This prevents the pedestal legs from sinking into the ground.

  The above-mentioned foundation structure requires foundation work for placing concrete at a required location on the site and work for fixing the legs of the gantry to the foundation of the placed concrete, which takes construction time and increases the construction cost.

  As one of the solutions, for example, a foundation structure has been proposed in which a pile is driven into the ground and the lower end of the pedestal leg is connected to the upper end of the pile (see Patent Document 1).

JP-A-5-3335

  In the foundation structure using the above-mentioned pile, it is not necessary to place concrete, so the construction time can be reduced and the construction cost can be reduced, but when driving the pile, for example, a slight amount in the ground Even if there is an obstacle, the pile is buried at a position deviated from a predetermined location, and the axis of the pile and the axis of the gantry leg may be displaced.

  In the above-described foundation structure in order to cope with such misalignment (construction error), the upper end portion of the pile and the pedestal leg portion are provided with a cylindrical support portion made of a concrete block having an inner diameter larger than the outer diameter thereof. To connect through.

  However, it is necessary to prepare in advance a plurality of support portions having different inner diameters depending on the degree of misalignment. Moreover, since it is necessary to fill and cure the gap formed between the pile or the leg and the support, it takes time and effort.

  In particular, in the case of a solar cell array platform in which a plurality of solar cell modules are connected in parallel, the number of piles to be driven to withstand wind pressure and the like is large, and the connection work between the pile and the platform leg is enormous. There is a demand for simplification of connection work.

  The present invention provides a foundation structure for a solar cell module or a solar cell array pedestal, which can easily connect a pile and a pedestal leg, and can reduce the construction time and the construction cost. Objective.

The foundation structure according to claim 1 of the present invention that achieves the above object is a foundation structure of a gantry that supports a solar cell module or a solar cell array, and is a cylindrical pile that is buried in a place where the gantry is installed A connecting shaft that is attached to the cylindrical pile, extends along an axial center thereof, and protrudes from an upper end of the cylindrical pile, a metal fitting that connects the leg of the gantry and the cylindrical pile, and the metal fitting The connecting shaft is movably attached to the connecting shaft, and the connecting shaft is fixed to a central portion of a fixed disk whose lower end portion is disposed in the upper end opening of the cylindrical pile, The metal fitting is moved and adjusted on the cylindrical pile so that the lower end of the leg portion is placed on the metal fitting with the connecting shaft penetrating the elongated hole, and connected to the cylindrical pile and the leg portion. characterized in that it.

  According to the basic structure of the present invention, it is possible to connect the upper end of the cylindrical pile and the lower end of the gantry leg by adjusting the misalignment between the axis of the gantry leg and the axis of the cylindrical pile, The connection work between the pile and the gantry is easy, and it is possible to reduce the construction time and the construction cost.

FIG. 1A is a plan view, and FIG. 1B is a longitudinal sectional view of an essential part, showing a first embodiment of the basic structure of the present invention. In the basic structure of the present invention shown in FIG. 1, when the center leg (eccentricity) occurs between the axis of the gantry leg and the axis of the cylindrical pile (steel pipe pile), FIG. 2A is a plan view and FIG. 2B is a vertical cross-sectional view of the main part. It is explanatory drawing explaining the construction process in the basic structure of 1st Example shown in FIG. It is a top view which shows the modification in the Example of Fig.1 (a), (b). The 2nd Example of the basic structure of this invention is shown, Fig.5 (a) is a longitudinal cross-sectional view of the principal part, FIG.5 (b) is a top view. It is the side view which abbreviate | omitted partially showing an example of the steel pipe pile used by the Example and modification of the foundation structure of this invention. It is explanatory side view of the state which supported the solar cell module or the mount for solar cell arrays using the basic structure of the Example of the basic structure of this invention, and its modification. It is a top view which shows the embedding location of the cylindrical pile which is a part of foundations of the mount frame shown in FIG. 7, and the mount frame.

  1st Example, 2nd Example of the basic structure of this invention, and its modification (FIG. 1 (a), (b), FIG. 2 (a), (b), FIG.4 and FIG.5 (a), ( b)), a required portion (for example, a leg portion 11 of the gantry 10 indicated by C in FIG. 8) is installed on the site where the gantry 10 (see FIG. 7) that supports the solar cell module or the solar cell array S is installed. For example, the winged steel pipe pile 20 shown in FIG. The winged steel pipe pile 20 is provided with a spiral wing 22 of almost one turn on the outer peripheral surface on the lower end side of a steel pipe pile main body 21, and a tip excavating blade 23 is provided on the bottom end of the pile main body 21. In addition, as a cylindrical pile, it is not limited to the steel pipe pile 20 with a wing | blade shown in FIG.

  A winged steel pipe pile (hereinafter referred to as a steel pipe pile) 20 is rotated by a rotary pushing device (auger not shown) connected to the upper end of the pile body 21 while the pile body 21 is raised on the ground. The pile main body 21 is pushed into the ground by rotating propulsion of the spiral blade 22 by causing the 22 to penetrate into the ground. The steel pipe pile 20 buried in the ground sinks into the ground by the spiral wing 22 or the like even if a load or a pulling force is applied, and is not pulled out from the ground. However, the pile main body 21 may be rotated in the inclined direction of the spiral blade 22 and displaced in the horizontal direction (causing misalignment) due to the influence of the ground or the like in the process of being buried in the ground. In other words, there is a case where the burial is displaced in the horizontal direction from the original planned burial point (a construction error may occur).

  The present inventors analyzed the data in detail about the past results of embedding about 3,500 steel pipe piles 20 in soft ground. As a result, the misalignment within 10 mm is about 30%, and the core within 10 mm and within 20 mm. It was found that the misalignment was about 40%, and the misalignment within 20 mm and within 30 mm was about 30%. When the ground is hard, the amount of misalignment is further increased and may be displaced by about 100 mm at maximum.

  The direction in which the misalignment occurs is not constant and varies, and the misalignment amount is also various. For this reason, it is difficult to directly connect the leg portion 11 of the gantry 10 (see FIG. 7) to the steel pipe pile 20.

  The foundation structure of the present invention connects a pile and a pedestal leg by interposing a misalignment adjusting mechanism at the upper end of the pile, and via a cylindrical support portion made of a concrete block as in the prior art. This eliminates the need for connection.

  Hereinafter, each Example of the basic structure of this invention and its modification are explained in full detail.

  1 (a), 1 (b), 2 (a) and 2 (b) show a first embodiment of the basic structure of the present invention.

  The basic structure of the first embodiment is a steel pipe pile 20 (see FIG. 6), a connection shaft 30 attached to the steel pipe pile 20 (pile main body 21), and a lower end of the leg portion 11 of the gantry 10 (see FIG. 7). And a metal fitting 40 that has a long hole 41 to which the connection shaft 30 is movably attached and is connected to the steel pipe pile 20. In addition, in the present Example, although the case where the leg part 11 has a hollow cross section is shown, it is not limited to this.

  A fixed disk 31 is disposed in the upper end opening 24 of the steel pipe pile 20 (pile main body 21), and the connection shaft 30 is attached through a fixing hole 32 provided in the center of the fixed disk 31. .

  The connection shaft 30 is made of, for example, a hexagonal bolt, passes through the fixing hole 32, extends along the axis of the steel pipe pile 20 (pile main body 21) (extends in line with the axis, or is parallel to the axis). Projecting from the upper end opening 24 of the steel pipe pile 20.

  The metal fitting 40 is a circular flat plate, and the elongated hole 41 is formed so as to extend in the diameter direction through the center. The diameter of the metal fitting 40 is set to approximately twice the diameter of the steel pipe pile 20 (pile main body 21). Although FIG. 1 and FIG. 2 show the metal fitting 40 in a disc shape, it is not limited to this and may be an ellipse or a rectangle.

  The long hole 41 is dimensioned in the longitudinal direction so as to be able to cope with misalignment (construction error) that occurs when the steel pipe pile 20 is buried. In the present embodiment, for example, the longitudinal dimension of the elongated hole 41 is set so as to be able to cope with misalignment of a maximum of 110 mm.

  A nut 34 is screwed into a portion of the connection shaft 30 that penetrates the elongated hole 41 and protrudes from the surface of the metal fitting 40 via a washer 33 and is tightened. Thereby, the said metal fitting 40 is connected to the steel pipe pile 20 (pile main body 21).

  The metal fitting 40 is moved and adjusted on the steel pipe pile 20 in accordance with the misalignment (construction error) caused when the steel pipe pile 20 is buried while the connection shaft 30 is passed through the elongated hole 41. It functions as a misalignment adjusting mechanism M that connects the steel pipe pile 20 and the lower end of the leg portion 11 of the gantry 10 without hindrance.

  FIGS. 1A and 1B show a state in which the lower end of the leg portion 11 is connected to the center of the surface of the metal fitting 40, and the upper end of the steel pipe pile 20 is connected to the center of the back surface of the metal fitting 40. That is, the steel pipe pile 20 is embedded without causing misalignment and connected to the leg portion 11 of the gantry (the axis of the leg portion 11 of the gantry 10 and the axis of the steel pipe pile 20 coincide with each other). Connected state). When the misalignment does not occur in this way, the connecting shaft 30 penetrates the central portion in the length direction of the long hole 41.

  2 (a) and 2 (b), the lower end of the leg 11 is connected to a position near one end of the surface of the metal fitting 40 (left side of the drawing), and the position near the other end of the back surface of the metal fitting 40 (right side of the drawing). A state in which the upper end of the steel pipe pile 20 is connected, that is, a state in which the steel pipe pile 20 is buried with a large misalignment and connected to the leg portion 11 of the gantry (the axis of the leg 11 of the gantry 10 and the A state in which the axis of the steel pipe pile 20 is not aligned with the shaft center and is connected by being displaced is shown. When misalignment occurs in this way, the connecting shaft 30 penetrates the other end of the long hole 41.

  FIG. 3 shows the construction process of the foundation structure of the present embodiment when the steel pipe pile 20 is embedded with a deviation from the axis of the leg 11. (1) The fixed disk 31 attached with the connecting shaft 30 penetrating through the fixing hole 32 is fixed in the upper end opening 24 of the steel pipe pile 20 (pile main body 21) by welding or the like. (2) The metal fitting 40 is placed on the steel pipe pile 20 (pile main body) so that the leg portion 11 is placed near one end of the front surface of the metal fitting 40 and the upper end opening 24 is located near the other end of the back surface of the metal fitting 40. The connecting shaft 30 is moved and adjusted in a state where the connecting shaft 30 is passed through the long hole 41, and after the connecting shaft 30 is positioned at the other end of the long hole 41, the nut 34 is screwed through the washer 33 (see FIG. 1B). The metal fitting 40 is connected to the steel pipe pile 20 (pile main body). (3) The leg portion 11 is lowered to a position near one end of the surface of the metal fitting 40 and fixed by welding or the like.

  1 (b), 2 (b), and 3 show a state in which the fixing hole 32 for allowing the connection shaft 30 to pass through the center of the fixing disk 31 is an elongated hole. By making the elongated hole, it becomes easy to cope with misalignment, the length of the elongated hole 41 of the metal fitting 40 can be shortened, and as a result, the dimension of the metal fitting 40 can be reduced. The fixing hole 32 is not limited to a long hole.

  In an actual construction site, steel pipe piles 20 are respectively buried in the site where the solar cell module or the solar cell array S is laid, for example, at a position indicated by reference numeral C in FIG. 8, and then on the steel pipe piles 20 exposed from the ground. A plurality of strings (not shown) are stretched so as to intersect (orthogonal) each other, and each intersection of strings is positioned at the axis A (see FIG. 3) of the leg 11 of the gantry 10 (see FIG. 7). Keep it. In other words, each location in the site where the axis A of each leg 11 set in advance in the construction drawing is located is indicated by the intersection of the strings. Moreover, it attaches so that the connection shaft 30 may protrude along the axial center B (refer FIG. 3) of the steel pipe pile 20 (pile main body 21) from the upper end opening part 24 of the steel pipe pile 20 (pile main body 21) as mentioned above. deep. And the direction of misalignment and the amount of misalignment of each steel pipe pile 20 embedded with the intersection of the strings as a mark are checked. Next, with respect to each steel pipe pile 20, as described above, the metal fitting 40 is placed on the steel pipe pile 20 (pile main body 21) in a state where the connection shaft 30 is passed through the long hole 41, and the movement adjustment is performed. That is, the metal fitting 40 is moved on the steel pipe pile 20 (pile main body 21) with the crossing point of the string as a mark (moving along the length direction of the long hole 41 or rotated with the connecting shaft 30 as a fulcrum). The lower end of the leg portion 11 is adjusted to be placed on the upper portion 40, and a nut 34 is screwed and tightened to a portion penetrating from the long hole 41 of the connecting shaft 30 through a washer 33, and the metal fitting 40 is attached to the steel pipe pile 20 (pile body 21). Thereafter, the gantry 10 is carried into the site, the leg 11 is lowered onto the metal fitting 40 with the crossing point of the string as a mark, the string is removed, and the lower end of the leg 11 is fixed to the metal fitting 40 by welding.

  Accordingly, the gantry 10 is supported by the steel pipe pile 20. The steel pipe pile 20 once buried in the ground sinks into the ground and is not pulled out from the ground even if a load or a pulling force is applied by the spiral blade 22 (see FIG. 6) or the like as described above. Therefore, even if wind pressure or the like acts on the solar cell module or solar cell array S (see FIG. 7), there is no possibility that the gantry 10 (leg part 11) will be lifted from the ground, and the solar cell module or solar cell array S or gantry 10 There is no possibility that the leg 11 sinks to the ground due to its own weight.

  According to the basic structure of the first embodiment, the direction of misalignment and the amount of misalignment of the buried steel pipe pile 20 are checked, and the steel pipe pile 20 is in a state where the metal fitting 40 is passed through the long hole 41 and the connecting shaft 30 is penetrated. Since the movement adjustment is performed on the upper end opening 24, the direction of causing the misalignment of the steel pipe pile 20 is not constant, and even if the misalignment amount is not constant, it is possible to cope with this. Moreover, it is not necessary to prepare a plurality of types of support portions having different inner diameters depending on the degree of misalignment as in the prior art, and further, concrete is filled in gaps formed between the piles and the leg portions and the support portions, and curing is performed. Therefore, it is possible to significantly reduce the construction time and reduce the construction cost.

  FIG. 4 shows a modification of the basic structure of the first embodiment shown in FIGS. 1 (a), 1 (b), 2 (a) and 2 (b).

  4, the same parts as those shown in FIGS. 1 (a), 1 (b), 2 (a), 2 (b) are denoted by the same reference numerals, and the description thereof is omitted.

  In the basic structure of this modification, the metal fitting 40a is elliptical, and the long hole 41a is formed in the center part of the metal fitting 40a along the long side direction. Other points are the same as in the first embodiment described above.

  FIG. 4 shows a case where the steel pipe pile 20 is buried with a misalignment, as in FIGS. 2 (a) and 2 (b), and the leg portion is positioned near one end of the surface of the metal fitting 40a (left side in the drawing). 11 is connected, and the upper end of the steel pipe pile 20 is connected to a position near the other end of the back surface of the metal fitting 40a (right side in the drawing).

  According to the foundation structure of this modification example, the direction causing the misalignment of the steel pipe pile 20 is not constant, and the misalignment amount is not constant, as in the foundation structure of the first embodiment described above. In addition to being able to cope with this, the construction time can be greatly shortened and the construction cost can be reduced. In addition, the metal fitting 40a is provided with a long hole 41a after ensuring the necessary strength. It is possible to reduce the weight by setting the minimum dimensions necessary to connect the steel pipe pile 20 and the leg 11 of the gantry 10, and carry it to the construction site and adjust the movement on the steel pipe pile 20. Make work easier.

  5A and 5B show a second embodiment of the basic structure of the present invention.

  5 (a) and 5 (b), the same parts as those shown in FIGS. 1 (a) and 1 (b) are denoted by the same reference numerals, and the description thereof is omitted.

  In the basic structure of the second embodiment, instead of fixing the leg portion 11 of the gantry 10 (see FIG. 7) to the metal fitting 40b by welding or the like, the leg connecting shaft 42 or the connecting shaft 30 attached to the elongated hole 41b is used. Connecting. The leg 11 is hollow, the bottom at the bottom is closed, and a bottom hole 11a through which the leg connecting shaft 42 or the connecting shaft 30 passes is formed. In addition, a rectangular window hole 11 b is formed on one side of the lower end of the leg portion 11.

  5 (a) and 5 (b) show the case where the steel pipe pile 20 is buried with misalignment, as in FIGS. 2 (a) and 2 (b). The lower end of the leg portion 11 is connected to the left side) via a leg connecting shaft 42, and the upper end of the steel pipe pile 20 is connected to the portion near the other end of the rear surface of the metal fitting 40b (right side of the drawing) via the connecting shaft 30. Is done.

  When connecting the leg 11, the leg connecting shaft 42 is inserted into the bottom hole 11a of the leg 11 from one end of the elongated hole 41b of the metal fitting 40b, and from the window hole 11b to the portion protruding into the leg 11 from the bottom hole 11a. The leg 11 is connected to the metal fitting 40b by screwing and tightening the nut 44 through the washer 43. As described above, the connecting shaft 30 penetrates the other end portion of the long hole 41, and the nut 34 is screwed and tightened to the connecting shaft 30 via the washer 33, whereby the steel pipe pile 20 (pile main body 21) is attached to the metal fitting 40b. ).

  When there is no misalignment, the connecting shaft 30 connects the metal fitting 40b and the steel pipe pile 20 while connecting the metal fitting 40b and the leg portion 11. That is, the connecting shaft 30 also serves as the leg connecting shaft 42. In this case, the nut 34 is screwed into the portion of the connecting shaft 30 protruding from the bottom hole 11a into the leg portion 11 through the washer 33 from the window hole 11b and tightened.

  The metal fitting 40b is also moved and adjusted on the steel pipe pile 20 in accordance with the misalignment (construction error) generated when the steel pipe pile 20 is buried with the connection shaft 30 penetrating the elongated hole 41b. It functions as a misalignment adjusting mechanism M that connects the steel pipe pile 20 and the lower end of the leg portion 11 of the gantry 10 without hindrance.

Incidentally, the back surface is provided with cross-sectional substantially U-shaped cover 35 of the fixed circular plate 31, that the connecting shaft 30 attached to the fixed circular plate 31 through the fixing hole 32a falls within pile body 21 In addition to preventing the hexagonal head of the connection shaft 30 from being rotated, the connection shaft 30 is prevented from spinning around.

  In the actual construction site, similarly to the first embodiment described above, the steel pipe piles 20 are respectively buried in the site where the solar cell module or the solar cell array S is laid, for example, at the location indicated by the symbol C in FIG. Thereafter, a plurality of strings (not shown) are stretched so as to cross (orthogonal) each other on the steel pipe pile 20 exposed from the ground, and each intersection point of the strings is an axis Aa of the leg portion 11 of the gantry 10 (FIG. 5 ( a) See)). In other words, each point in the site where the axial center Aa of each leg 11 set in advance in the construction drawing is indicated by the intersection of the strings. Moreover, it attaches so that the connection shaft 30 may protrude along the axial center Bb (refer FIG. 5A) of the steel pipe pile 20 (pile main body 21) from the upper end opening part 24 of the steel pipe pile 20 (pile main body 21). . And the direction of misalignment and the amount of misalignment of each steel pipe pile 20 embedded with the intersection of the strings as a mark are checked. Next, with respect to each steel pipe pile 20, as described above, the metal fitting 40b is placed on the steel pipe pile 20 (pile main body 21) in a state where the connection shaft 30 is passed through the long hole 41b, and the movement adjustment is performed. That is, the metal fitting 40b is moved on the steel pipe pile 20 (pile main body 21) with the crossing point of the string as a mark (moving along the length direction of the long hole 41b or rotated with the connecting shaft 30 as a fulcrum). Adjustment is made so that the entire lower end of the leg portion 11 is placed on 40b, and a nut 34 is screwed and tightened to a portion penetrating from the long hole 41b of the connecting shaft 30 via a washer 33, and the metal fitting 40b is attached to the steel pipe pile 20 (pile main body). 21). Further, the leg connecting shaft 42 is inserted and attached to the elongated hole 41b so as to be located below the intersection of the straps. Thereafter, the strap is removed, the gantry 10 is carried into the site, the leg 11 is lowered onto the metal fitting 40 with the leg connecting shaft 42 as a mark, and the leg connecting shaft 42 is inserted into the bottom hole 11a of the leg 11. Then, the nut 44 is screwed into the portion protruding from the bottom hole 11a into the leg portion 11 through the washer 43 from the window hole 11b and tightened to connect the leg portion 11 to the metal fitting 40b.

  Accordingly, the gantry 10 is supported by the steel pipe pile 20. The steel pipe pile 20 once buried in the ground sinks into the ground and is not pulled out from the ground even if a load or a pulling force is applied by the spiral blade 22 (see FIG. 6) or the like as described above. Therefore, even if wind pressure or the like acts on the solar cell module or solar cell array S (see FIG. 7), there is no possibility that the gantry 10 (leg part 11) will be lifted from the ground, and the solar cell module or solar cell array S or gantry 10 There is no possibility that the leg 11 sinks to the ground due to its own weight.

  According to the basic structure of the second embodiment, the misalignment direction and the misalignment amount of the steel pipe pile 20 embedded in the same manner as in the first embodiment described above are checked, and the fitting shaft 40b is connected to the elongated hole 41b. Since it is the structure which adjusts movement (it moves along the length direction of the long hole 41b, or rotates using the connection shaft 30 as a fulcrum) on the upper end opening part 24 of the steel pipe pile 20 in the penetrated state, the core of the steel pipe pile 20 Even if the direction in which the deviation occurs is not constant, and the amount of misalignment is not constant, it is possible to cope with this. In addition, after removing the string indicating the axial center position of the leg portion 11 at the intersection, the leg connecting shaft 42 attached to the elongated hole 41b becomes a mark indicating the axial center position of the leg portion 11, so that the construction work efficiency is improved. It is possible to improve. Moreover, it is not necessary to prepare a plurality of types of support portions having different inner diameters depending on the degree of misalignment as in the prior art, and further, concrete is filled in gaps formed between the piles and the leg portions and the support portions, and curing is performed. Therefore, it is possible to significantly reduce the construction time and reduce the construction cost.
