Description

  The present invention relates to a connection structure between a superstructure and a pile that supports the superstructure.

When installing a solar cell module or solar cell array to be used in a photovoltaic power generation system, for example, a concrete base is constructed by placing concrete in advance at a planned installation location, and the concrete base is used for the solar cell module or solar cell array. The foundation structure that fixes the legs of the gantry (superstructure) is generally adopted, but the foundation work for placing concrete in the planned installation location and the gantry (superstructure) on the foundation of the cast concrete of the legs is necessary to work and to fix the, it takes a long construction time, construction cost increases.

  As one of the solutions, instead of concrete foundation, for example, a steel pipe pile is driven into the ground, and the bottom of the leg of the gantry (superstructure) is connected to the pile head of the steel pipe pile protruding from the ground. The law is known. However, when embedding steel pipe piles, the steel pipe piles may be displaced horizontally from the planned installation position due to the influence of the ground, etc. (may cause misalignment), and the pile head height from the ground Construction errors may occur, such as being buried below the set height. For this reason, it has been proposed to arrange a connection structure for connecting an upper structure by adjusting a construction error such as misalignment on the pile head of the steel pipe pile (see Patent Document 1).

It is explanatory side view of the state which connected and supported the solar cell module as an upper structure or the mount for solar cell arrays to the steel pipe pile using the connection structure of FIG.

  In the embodiment of the connection structure of the present invention (see FIGS. 1, 2, 8, and 14A), a gantry 10 that supports a solar cell module or a solar cell array S (see FIG. 15) as an upper structure. For example, a winged steel pipe pile 20 shown in FIGS. 9 (a) and 9 (b) is used as a pile embedded in each of the planned installation locations of the site where (see FIG. 15) is installed. This winged steel pipe pile 20 is provided with a substantially one-turn spiral blade 22 on the outer peripheral surface on the lower end side of a pile main body 21 made of steel pipe, and tip excavating blades 23 are provided on both ends in the radial direction of the bottom bottom of the pile main body 21. It is done. In addition, as a pile, it is not limited to the winged steel pipe pile 20 shown to Fig.9 (a), (b).

  A torque transmission fitting 24 having an I-shape in a plan view extending in the radial direction of the pile head 21a before being embedded in a pile head 21a of a winged steel pipe pile (hereinafter referred to as a steel pipe pile) 20 (see FIG. 7A). ) Is fixed by welding. And in the state which raised the pile main body 21 on the ground, the rotation cap Fa (refer FIG. 10 (a)) from which the terminal provided in the auger connection flange F of a pile rotation embedding apparatus (auger not shown) is divided into two or The torque transmission bracket 24 is sandwiched by a rotating cap Fb (see FIG. 11 (a)) whose ends are divided into four so that the rotational force is transmitted from the pile rotating embedding device to the steel pipe pile 20, and the pile main body by the pile rotating embedding device. The pile main body 21 is pushed into the ground by the rotational propulsion of the spiral wing 22 by rotating 21 and causing the spiral wing 22 to bite 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. Moreover, the height of the pile head from the ground may deviate from the planned height. That is, construction errors may occur.

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. 15) to the steel pipe pile 20.

Connecting structure of the present invention, which as diverse as misalignment connects the legs 11 of the gantry 10 in without any problem pile head 21a also be present (superstructure) causes a troublesome adjustment operation It can be connected without connecting.

Is used. A hexagonal nut 25 is fixed to the center of the upper surface of the torque transmission fitting 24 as shown in FIG. Instead of the hexagon nut 25, a torque transmission fitting 24a provided with a screw hole 25a as shown in FIG. 7B may be used.

The connection structure M extends along the central axis of the steel pipe pile 20 (pile main body 21) by screwing the lower end portion into the hexagon nut 25, and the upper end portion (head 30a) protrudes from the pile head 21a. The cross section has a connecting shaft 30 made of a bolt, a horizontal piece portion 32 provided with a loose hole 31 for adjusting misalignment into which the connecting shaft 30 is inserted, and a vertical piece portion 34 attached to the leg portion 11 of the gantry 10. An intermediate having an L-shaped adjustment fitting (hereinafter referred to as an L-shaped adjustment fitting) 35 and a through-hole 36 which is disposed between the pile head 21a and the horizontal piece 32 and through which the connecting shaft 30 passes. A metal fitting 37 and a holding member 40 provided on the L-shaped adjustment metal fitting 35 so as to cover the loose adjustment hole 31 for adjusting the misalignment and provided with a misalignment adjusting long hole 41 into which the connecting shaft 30 is inserted. It is prepared for. The vertical piece 34 that is attached to the leg 11 of the gantry 10 of the L-shaped adjustment fitting 35 is provided with an attachment adjustment long hole 33 (see FIG. 3) that can adjust the attachment position of the leg 11.

  The connection shaft 30 has an intermediate fitting 37 mounted on the pile head 21 a of the buried steel pipe pile 20, an L-shaped adjustment fitting 35 is stacked on the intermediate fitting 37, and a pressing member 40 is further placed on the L-shaped adjustment fitting 35. After that, the lower end portion is inserted into the pile head 21a through the washer 38, the misalignment adjusting long hole 41, the misalignment adjusting loose hole 31, and the through hole 36, and screwed into the hexagon nut 25. It is temporarily tightened. After adjusting the movement of the L-shaped adjustment fitting 35 by rotating or sliding on the intermediate fitting 37 in accordance with the misalignment of the steel pipe pile 20 with the holding member 40 placed, the connection shaft 30 is connected to the hexagon nut 25. By tightening, the head 30 a which is the upper end portion of the connection shaft 30 fixes the L-shaped adjustment fitting 35 and the intermediate fitting 37 to the pile head 21 a of the steel pipe pile 20 via the washer 38 and the pressing member 40.

As shown in FIGS. 3 and 4 (a), the misalignment adjusting loose hole 31 provided in the horizontal piece 32 of the L-shaped adjustment fitting 35 is a circular shape having an inner diameter slightly smaller than the inner diameter of the pile head 21a. It is a hole. The length of one side as shown in FIG. 4 (b) may be slightly shorter square rectangular hole 31a than the inner diameter of the pile cap 21a. As shown in FIG. 3, the attachment adjustment long hole 33 provided in the vertical piece portion 34 of the L-shaped adjustment metal fitting 35 is provided along the short side direction of the vertical piece portion 34, and the vertical piece portion 34. Some of them are provided along the long side direction. The misalignment adjusting loose hole 31 and the attachment adjusting long hole 33 are set so that the steel pipe pile 20 can cope with the embedding caused by the misalignment in the front / rear / left / right direction or the up / down direction from the planned embedding position. It is.

  Between the horizontal piece part 32 and the vertical piece part 34, as shown in FIG. 3, substantially triangular support plates 39 are respectively provided at both ends in the long side direction. Since the wind pressure received by the solar panel S and the gantry 10 acts on the vertical piece 34 in addition to the load of the solar panel S and the gantry 10 (see FIG. 15), the vertical piece 34 is in relation to the horizontal piece 32. The L-shaped adjustment fitting 35 is reinforced so as not to wobble.

  The intermediate fitting 37 is formed in a disk shape as shown in FIG. 5A, and has a diameter that is larger than the outer diameter of the steel pipe pile 20 and slightly smaller than the dimension of the horizontal piece portion 32 in the short side direction. (Refer FIG. 1, FIG. 2) and the said L-shaped adjustment metal fitting 35 (the said horizontal piece part 32) are reinforced.

  The pressing member 40 covers the misalignment adjusting loose hole 31 and fixes the L-shaped adjusting fitting 35 (the horizontal piece portion 32) to the pile head 21a side by the head portion 30a of the connecting shaft 30. As shown in FIG. 6 (a), it has a rectangular plate shape having a short side having a length substantially equal to the diameter of the pile head 21a and a long side longer than the short side. The misalignment adjusting long hole 41 is provided at the center of the pressing member 40 so as to extend in the short side direction. The width of the misalignment adjusting long hole 41 is set to a dimension slightly larger than the diameter of the connection shaft 30, and the length is set to the same dimension as the diameter or one side length of the misalignment adjusting loose hole 31. The That is, the width and length of the misalignment adjusting long hole 41 are adjusted so that the pressing member 40 is connected to the connecting shaft 30 together with the L-shaped adjusting bracket 35 (the horizontal piece portion 32) when adjusting the misalignment. It is set so that it can be smoothly rotated and slid on the intermediate fitting 37.

  FIG. 8 shows a modification of the connection structure M of the present embodiment. 8, parts that are the same as the parts shown in FIGS. 1 and 2 are given the same reference numerals, and descriptions thereof are omitted.

  In this modification, the torque transmission fitting 24a shown in FIG. 7B is fixed inside the pile head 21a of the steel pipe pile 20, and the lower end of the connecting shaft 30 is inserted into the screw hole 25a provided at the center of the upper surface of the torque transmission fitting 24a. By screwing the portions, the connection shaft 30 is erected along the central axis of the steel pipe pile 20 (pile main body 21), and the upper end portion (head) is protruded from the pile head 21a. Other than that, it is the same as the connection structure shown in FIGS.

  Next, the construction procedure of the connection structure M of the above-described embodiment will be described.

  After embedding the steel pipe pile 20 at the planned embedding position, the intermediate fitting 37 is placed on the pile head 21 a so that the through hole 36 is located at the center axis position of the steel pipe pile 20. Next, the horizontal piece 32 of the L-shaped adjustment fitting 35 is placed on the intermediate fitting 37 so that the misalignment adjusting loose hole 31 is positioned on the through hole 36, and further, the misalignment adjusting loose hole 31 is covered. Then, the pressing member 40 is placed on the horizontal piece 32 and the misalignment adjusting elongated hole 41 is positioned on the through hole 36 and the misalignment adjusting loose hole 31.

  Next, the connecting shaft 30 is inserted into the pile head 21 a of the steel pipe pile 20 through the washer 38, the misalignment adjusting long hole 41, the misalignment adjusting loose hole 31, and the through hole 36 from above the pressing member 40. The lower end portion of 30 is screwed into a hexagon nut 25 provided on the torque transmission fitting 24 and temporarily tightened, the connection shaft 30 is raised along the central axis of the steel pipe pile 20, and the head portion 30 a of the connection shaft 30 is piled up. It protrudes from 21a.

  After this, the connecting shaft 30 is tightened. When the steel pipe pile 20 is buried with misalignment, before the connecting shaft 30 is tightened, the connecting shaft 30 is adjusted with a misalignment adjusting long hole 41, for misalignment adjustment. The horizontal piece 32 of the L-shaped adjustment fitting 35 is rotated on the intermediate fitting 37 with the pressing member 40 placed in accordance with the amount of misalignment and the direction of misalignment while being inserted into the loose hole 31 and the through hole 36. The vertical piece 34 of the L-shaped adjustment fitting 35 is pressed against the leg 11 of the gantry 10 by moving (sliding).

  For example, as shown in FIG. 12 (a), when the steel pipe pile 20 is embedded with a misalignment in one direction (right direction in the drawing), the L-shaped adjustment fitting 35 is placed with the pressing member 40 mounted thereon. The horizontal piece 32 is moved and adjusted on the intermediate fitting 37 in the other direction (left direction in the drawing) by a distance corresponding to the amount of misalignment, so that the vertical piece 34 of the L-shaped adjustment fitting 35 becomes the leg 11 of the gantry 10. Press.

  Also, as shown in FIG. 12B, when the steel pipe pile 20 is embedded with the misalignment in the other direction (the left direction in the drawing), the L-shaped adjustment fitting 35 is mounted with the pressing member 40 mounted thereon. The horizontal piece 32 is moved and adjusted on the intermediate fitting 37 in one direction (rightward in the drawing) by a distance corresponding to the amount of misalignment, so that the vertical piece 34 of the L-shaped adjustment fitting 35 becomes the leg 11 of the gantry 10. Press.

  Further, as shown in FIG. 13A, when the steel pipe pile 20 is embedded with an eccentricity in the oblique direction, the horizontal piece 32 of the L-shaped adjustment fitting 35 is placed in the middle with the pressing member 40 placed thereon. The metal plate 37 is rotated in the direction of the arrow A with the connecting shaft 30 as a fulcrum, and is moved and adjusted in the direction of the arrow B by a distance corresponding to the misalignment amount. 11 against.

  In this way, the horizontal piece 32 of the L-shaped adjustment fitting 35 is rotated on the intermediate fitting 37 and moved (slided) in a state where the pressing member 40 is placed in accordance with the misalignment of the steel pipe pile 20 in the horizontal direction. When the connecting shaft 30 is tightened after the vertical piece 34 of the L-shaped adjustment fitting 35 is pressed against the leg 11 of the gantry 10, the head 30 a of the connecting shaft 30 is L-shaped via the washer 38 and the pressing member 40. The shape adjustment fitting 35 and the intermediate fitting 37 are fixed to the pile head 21a of the steel pipe pile 20.

  Thereafter, the leg portion 11 of the gantry 10 is fixed to the portion of the attachment adjustment long hole 33 provided in the vertical piece portion 34 of the L-shaped adjustment fitting 35 by a fastening member 50 made of a bolt and a nut. At this time, as shown in FIG. 13 (b), even when the pile head height (height from the ground) of the steel pipe pile 20 is deviated from a preset height, it is embedded by the fastening member 50. Can be fixed to the portion of the attachment adjustment elongated hole 33 of the vertical piece 34.

Thereby, even if it is a case where the steel pipe pile 20 raise | generates misalignment etc. and is embed | buried, the leg part 11 of the mount frame 10 can be connected to the pile head 21a of the steel pipe pile 20 without any trouble. 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 a spiral blade 22 (see FIG. 9) or the like. Therefore, even if wind pressure or the like acts on the solar cell module or solar cell array S (see FIG. 15), there is no possibility that the gantry 10 (leg 11) will be lifted from the ground, and the solar cell module or solar cell array S or gantry 10 leg 11 by its own weight, such as there is no risk of subsidence in the ground.

  According to the connection structure M of the present embodiment, the L-shaped adjustment fitting 35 is rotated on the intermediate fitting 37 in a state where the pressing member 40 is placed according to the misalignment amount and misalignment direction of the buried steel pipe pile 20. Although the sliding adjustment is carried out by sliding, the loose hole 31 for misalignment adjustment has an inner diameter slightly smaller than the inner diameter of the pile head 21a, and the elongated hole 41 for misalignment adjustment is also slightly shorter than the inner diameter of the pile head 21a. Therefore, it is possible to cope with various misalignment amounts and misalignment in the misalignment direction. Further, in this misalignment adjustment operation, the pressing member 40 is placed on the horizontal piece portion 32 of the L-shaped adjustment fitting 35 so as to cover the misalignment adjusting loose hole 31, and the connecting shaft 30 is connected to the misalignment adjusting long hole 41. The pressing member 40 and the L-shaped adjustment fitting 35 are detached from the intermediate fitting 37 because the center displacement adjustment loose hole 31 and the through hole 36 are inserted, that is, temporarily fixed by the connecting shaft 30. There is no fear and it can be done smoothly. Further, the connecting shaft 30 is connected to the steel pipe pile 20 by using the torque transmission fittings 24, 24a used when the steel pipe pile 20 is buried, whereby the holding shaft 40, the L-shaped adjusting fitting 35, Since the intermediate fitting 37 is fixed to the pile head 21a, the connection structure M can be simplified.

  Further, according to the connection structure M of the present embodiment, as in the prior art, it is not necessary to adjust the movement of the member in the narrow pile head space in order to adjust the misalignment. As a result, the gantry 10 and the steel pipe pile The connection work (construction) time with 20 pile heads can be shortened, and the construction cost can be reduced. In particular, in the case of the platform 10 of the solar cell array S in which a plurality of solar cell modules are connected in parallel, the number of steel pipe piles 20 to be driven so as to withstand wind pressure and the like is large. The amount of connection work with 11 is enormous, and there is a problem that the construction time becomes long and the construction cost becomes high, but this can be solved.

  14 (a) and 14 (b) show an embodiment for dealing with the case where the steel pipe pile 20 is sunk due to secular change or the like in the connection structure M shown in FIG. In FIG. 14A, the same components as those shown in FIG. 1 and FIG.

  In the present embodiment, a shim 60 as a height adjustment member is interposed between the L-shaped adjustment fitting 35 and the intermediate fitting 37 in accordance with the amount of settlement of the steel pipe pile 20. In addition, it is not limited to subsidence of the steel pipe pile 20 by secular change, For example, also when the steel pipe pile 20 is embed | buried deeply, when it embeds deeply, shim 60 is similarly between the L-shaped adjustment metal fitting 35 and the intermediate metal fitting 37. Needless to say, the present invention can also be applied to the case where the height is adjusted to the height of the gantry 10 set in advance. The connection structure is the same as that shown in FIGS. 1 and 2 except that a shim 60 is interposed.

  For example, as shown in FIG. 14B, the shim 60 has a substantially rectangular plate shape and is provided with a U-shaped attachment groove 61 that opens on one side thereof. When the shim 60 is interposed in accordance with the sinking amount of the steel pipe pile 20, the connection shaft 30 is loosened or replaced with a long one, and the state in which the gantry 10 is slightly lifted is maintained. The shim 60 is inserted between the intermediate fitting 37 from one side thereof, and the connecting shaft 30 is inserted into the mounting groove 61. When the insertion of the shim 60 is completed, the gantry 10 is lowered and the connecting shaft 30 is tightened. Thereby, the height of the gantry 10 can be maintained. The shim 60 may be formed of a thin plate, and a plurality of shims 60 may be stacked to finely adjust the height of the gantry 10. When the settlement of the steel pipe pile 20 further progresses due to secular change, the shim 60 may be added.

  In addition, when the steel pipe pile 20 sinks in the ground due to secular change, for example, as shown in FIG. 2, when the pair of leg portions 11 are configured in a reverse C shape, the pair of leg portions 11 are brought close to each other. Thus, it is possible to cope with the rotation adjustment (rotation adjustment to raise the inclined leg portion 11). However, in order to do this, it is necessary to periodically perform the rust prevention treatment of the leg part 11 or to construct the leg part 11 from a material that does not easily rust, which may increase the cost. On the other hand, in the connection structure M of the present embodiment shown in FIGS. 14A and 14B, the shim 60 is an extremely simple configuration in which the shim 60 is interposed between the L-shaped adjustment fitting 35 and the intermediate fitting 37. There is no risk of increasing.

  The connection structure of the present invention is not limited to the connection between the solar cell module or the solar cell array base 10 and the steel pipe pile 20 shown in the above-described embodiment. For example, the upper structure such as a wind power generator or a power transmission tower. This also applies to the connection between objects and piles.

  The connection structure between the upper structure and the pile according to the present invention prevents the upper structure such as the solar cell module or the array of the solar cell array from being lifted by wind pressure or the like, and prevents the upper structure from sinking due to its own weight. Applied to prevent.
