Description

  The present invention relates to a connecting structure and a connecting device, and more particularly, to a connecting structure in which a support body that supports equipment such as a solar cell panel and an antenna and a mount of such equipment is connected, and a connecting device used for such connection. .

  2. Description of the Related Art Conventionally, there is a type of solar power generation system that is an example of equipment in which a solar panel is installed on the ground. In this type of photovoltaic power generation system, solar panels are installed on the ground by fixing them to a concrete foundation laid on the ground or by fixing them to steel pipe piles that are driven into the ground. Yes.

  When a concrete foundation is used, the position of the anchor bolt connected to the solar panel base can be determined with relatively high accuracy, but it takes time and effort to install and remove the concrete foundation. When using steel pipe piles, it takes less time and effort to embed or remove the steel pipe piles than when using a concrete foundation, but it is difficult to accurately determine the position of the steel pipe piles. This is because when steel pipe piles are driven into the ground, it is necessary to have sufficient strength to support the solar cell panel mount, and for that purpose, it is necessary to drive the steel pipe piles deep into the ground, where there were stones and gravel. In this case, the axis of the steel pipe pile may be displaced.

  Measures have conventionally been taken against such misalignment of the steel pipe pile.

  For example, the countermeasure of shortening the length of a support pile by using the spiral pile which is harder to come out compared with a cylindrical steel pipe pile, and suppressing position shift is performed.

  Also, measures to absorb the misalignment of the steel pipe pile in the bolt insertion long hole of the base member by making the bolt insertion hole of the part (base member) fixing the spiral pile of the solar cell panel base into a long hole Has also been done.

  However, the displacement of the spiral pile may reach as much as 50 mm in the test. In this way, when the spiral pile is greatly displaced in the direction orthogonal to the longitudinal direction of the long hole of the base member, the bolt member of the spiral pile cannot be passed through the bolt insertion long hole of the base member.

  Therefore, conventionally, as a mounting tool for mounting the base member of the solar cell panel base to a support such as a spiral pile, the positional deviation between the support and the base member is perpendicular to the longitudinal direction of the base member. There are those that can absorb in any of these directions (for example, FIG. 7 of Patent Document 1).

  Such a fixture has a top plate, a bottom plate, a vertical plate that connects the top plate and the bottom plate, and a bolt insertion length formed on the top plate in a specific direction between the support pile and the gantry. It absorbs with a hole, and it is comprised so that the position shift of the direction orthogonal to the specific direction of a support pile and a mount may be absorbed with the long hole for bolt insertion formed in the bottom plate.

  In such a fixture, even when a support pile that is buried in the ground while rotating, such as a spiral pile, is used so that the support pile and the mount can be connected regardless of the rotation angle of the support pile. The bottom plate is fixed to one bolt member provided at the center of rotation of the head of the support pile.

  However, when the support pile and the fixture are fixed with a single bolt member in this way, sufficient fixing strength cannot be obtained, and the support is supported when a large load is applied to the solar cell panel due to strong wind or snow. There is a risk of damage to the joint between the pile and the fixture.

  On the other hand, in order to ensure the strength of the joint portion, it is conceivable to fasten the bottom plate of the fixture and the pile head portion of the support pile with a plurality of bolts.

  For example, as disclosed in Patent Document 2 (FIG. 4), when arc-shaped long holes are formed in both the bottom plate of the fixture and the pile head portion of the support pile, the bottom plate of the fixture and the support pile Although the pile head portion can be joined with a plurality of bolts, it becomes impossible to absorb the positional deviation in the linear direction between the fixture and the support pile.

  Moreover, as disclosed in Patent Document 3 (FIG. 1), when a straight long hole is formed on one of the bottom plate of the fixture and the pile head portion of the support pile, and an arc long hole is formed on the other side In the mounting fixture and the support pile, it is possible to absorb both the positional deviation in the rotation direction and the positional deviation in the linear direction, but to absorb the positional deviation in the rotational direction by absorbing the positional deviation in the linear direction. The margin will be consumed. Therefore, when a large misalignment in the linear direction occurs, the amount of misalignment in the rotational direction that can be absorbed originally becomes small, the misalignment in the rotational direction cannot be absorbed, and the attachment tool and the support pile cannot be attached. It becomes difficult.

And a second fixing portion 20 fixed by two fastening members T1.

  In the connection structure 100a, the second member 201 has an axis. The positional deviation in the first direction in the plane perpendicular to the axis of the second member 201 between the first member 210 and the second member 201 is different from the position of the first fixing unit 10 and the first member. A first direction in a plane perpendicular to the axis of the second member 201 between the first member 210 and the second member 201 that is absorbed by relatively adjusting the position of the member 210; The misalignment in the intersecting second direction is absorbed by relatively adjusting the position of the first fixing portion 10 and the position of the first member 210, and the first member 210 and the second member. The positional deviation in the rotational direction around the axis of the second member 201 with respect to 201 is absorbed by relatively adjusting the position of the second fixing portion 20 and the position of the second member 201. Thus, the 1st member 210, the 2nd member 201, and the connecting instrument 100 are comprised.

  For example, each of the first fixing part 10 and the first member 210 has one or more holes for mounting the first fastening member T2, and the position of the first fixing part and the first member Are formed in each of the second fixing portion 20 and the second member 201. Each of the second fixing portion 20 and the second member 201 has one or more holes for mounting the second fastening member T1. Thus, it is only necessary that a hole for relatively adjusting the position of the second fixing portion 20 and the position of the second member 201 is formed.

  Here, as an example of the hole, a linear long hole or an arc long hole is used. In the present specification, the straight long hole includes not only a straight long hole but also a plurality of round holes arranged in a straight line, and the arc long hole extends along the circular arc.

  For example, in the connection structure 100a shown in FIG. 2, the linear elongated holes 11a to 11d and the linear elongated holes for attaching the first fastening member T2 to the first fixing portion 10 and the first member 210, respectively. 210a is formed, and arc-shaped elongated holes 21a and 21b and arc-shaped elongated holes 212 for mounting the second fastening member T1 are formed in the second fixing portion 20 and the second member 201, respectively. ing. Here, the fastening members T1 and T2 include a bolt Bt and a nut Nt. When the fastening member is attached, the bolt Bt is inserted into the long hole and the nut Nu is attached to the bolt inserted into the long hole. Is intended. In addition, the linear long hole formed in the 1st fixing | fixed part 10 is not limited to four, What is necessary is just one or more. Moreover, the linear long hole formed in the 1st member 210 should just be at least 1 or more in the location corresponding to each connection instrument. Furthermore, at least one arc-shaped elongated hole formed in the second fixing portion 20 and the second member 201 may be provided.

  Further, in the connecting device 100, the linear elongated holes 11 a to 11 d formed in the first fixing portion 10 are in the state where the first fixing portion 10 is fixed to the first member 210. It is comprised so that it may cross | intersect a pair of linear long hole 210a, 210b formed in this. Here, the linear elongated holes 11a to 11d of the first fixing portion 10 are arranged in parallel, and extend along a direction (Y direction) orthogonal to the longitudinal direction (X direction) of the first member 210. The straight long holes 210 a and 210 b of the member 210 are arranged so as to be positioned on a straight line, and extend along the longitudinal direction (X direction) of the first member 210. However, the linear elongated holes 11a to 11d of the first fixing portion 10 and the linear elongated holes 210a and 210b of the first member 210 are not limited to those extending along these directions, and the respective longitudinal directions intersect. If you do.

  Furthermore, when the second fixing part 20 is fixed to the second member 201, the connecting device 100 includes a circumference defined by arc-shaped long holes 21a and 21b formed in the second fixing part 20, and The circumference defined by the arc-shaped long hole 212 formed in the second member 201 is configured to coincide with the circumference. However, the circumferences defined by these arc-shaped elongated holes 21a, 21b and 212 do not need to be exactly the same, and absorb the displacement in the rotational direction between the first member 210 and the second member 201. Thus, when fixing the 2nd member 201 to the 2nd fixing | fixed part 20, it should just correspond to the grade which can attach fastening member T1 to each circular arc-shaped long hole 21a, 21b, and 212.

Yes. These arc-shaped long holes 21a and 21b are arranged so as to be line-symmetric and point-symmetric.

  When the base member (first member) 210 and the support pile (second member) 201 of the gantry 202 are connected by the connecting device 100 having such a configuration, the connection tool 100 is generated on a plane perpendicular to the rotation axis of the support pile 201. The positional deviation in the X direction and the Y direction between the base member 210 and the support pile 201 utilizes the straight long holes 11a to 11d of the top wall 10 and the straight long holes 210a and 210b facing the base member 210. Then, it is absorbed by relatively adjusting the position of the upper surface wall 10 and the position of the base member 210. Further, the positional deviation in the rotation direction around the rotation axis of the support pile 201 generated between the base member 210 and the support pile 201 is caused by the arc-shaped long holes in the bottom walls 20a and 20b and the arc-shaped long holes in the support pile 201. It is absorbed by adjusting the position of bottom wall 20a, 20b and the position of support pile 201 relatively using 201b.

  Next, a method for connecting the base member 210 of the solar cell panel base and the support pile 201 using the connecting device 100 will be described.

  FIG. 8 is a view for explaining a method of connecting the support pile and the base member by the connecting device. In the following description, the linear elongated holes 11a to 11d formed in the upper surface wall 10 of the connecting device 100 will be described as the linear elongated holes 11 when it is not necessary to distinguish them. Similarly, the bottom walls 20a and 20b of the connecting device 100 and the arc-shaped long holes 21a and 21b formed in the bottom walls 20a and 20b are respectively the bottom wall 20 and the circle when there is no need to distinguish between them. The arc-shaped long hole 21 will be described.

[Installation of connecting device 100]
First, an operator arrange | positions the connection tool 100 above the head 201b of the support pile 201 embedded in the installation site G of a solar power generation system (for example, refer FIG. 2).

  Next, the operator has an arc-shaped elongated hole 21 formed in the bottom wall 20 of the connecting device 100 and an arc-shaped length of a flat plate member (pile head flat plate member) 201 b that forms a pile head of the support pile 201. The center of the arc-shaped long hole 21 of the bottom wall 20 and the center of the arc-shaped long hole 212 of the pile head flat plate member 201b are aligned so that the bolt Bt of the fastening member T1 can be inserted into the hole 212. Furthermore, at this time, the orientation of the connecting device 100 is such that the longitudinal direction of the linear elongated hole 11 formed in the upper surface wall 10 is orthogonal to the longitudinal direction of the base member 210 disposed on the connecting device 100. Thus, it aligns by the relative rotational movement of the bottom face wall 20 and the support pile 201. FIG. Thereafter, the operator inserts a bolt Bt of the fastening member T1 into the flat washer Wp1 from above the bottom wall 20 into the arc-shaped long hole 21 formed in the bottom wall 20 and the arc-shaped long hole 212 of the pile head flat plate member 201b. The flat washer Wp, the spring washer Ws, and the nut Nt are attached to the tip of the inserted bolt Bt, and the connecting device 100 is fixed to the support pile 201 with the bolt Bt and the nut Nt.

  Since the plurality of support piles 201 are embedded in the installation site G of the photovoltaic power generation system, the connecting device 100 is similarly fixed to the support pile 201 for the other support piles 201.

  In the example illustrated in FIG. 2, an example in which the connection tool 100 and the support pile 201 are fastened at four places has been described, but the number of places to be fastened is not limited to four. In order to fix the connecting device 100 and the support pile 201, it is sufficient to fasten at one place at a minimum. However, there may be two or more fastening points. This is because the fixing strength increases as the number of fastening points increases.

[Attaching the base member 210]
Then, an operator arrange | positions the base member 210 of a mount on the upper surface wall 10 of the connection tool 100 fixed to the support pile 201 (refer FIG. 8). In this state, the operator fastens the linear elongated holes 210a and 210b of the base member 210 and the linear elongated holes 11a, 11b and 11d of the upper surface wall 10 of the connecting device 100 intersecting with these linear elongated holes. The bolt Bt of T2 is inserted through, for example, a flat washer from the back side of the upper surface wall 10 of the connecting device 100, and the flat washer Wp, the spring washer Ws, and the nut Nt are attached to the tip of the inserted bolt Bt, and the bolt Bt and the nut Nt Thus, the base member 210 is fixed to the connecting device 100. As a specific example, as shown in FIG. 8, the straight long hole 210 a of the base member 210 and the straight long hole 11 a of the upper surface wall 10 of the connecting device 100 are fastened by the fastening member T <b> 2, The straight long hole 210a and the straight long hole 11b of the upper surface wall 10 of the connecting device 100 are fastened by the fastening member T2, and the straight long hole 210b of the base member 210 and the straight long length of the upper surface wall 10 of the connecting device 100 are fastened. The hole 11d is fastened by the fastening member T2. The reason for fastening in three places in this way is to prevent relative side slip between the base member 210 and the connecting device 100.

  Thereby, the connection between the base member 210 and the support pile 201 is completed.

  In the example shown in FIG. 8, the connection tool 100 and the base member 210 are fastened at three points (three linear long holes 11 a, 11 b, 11 d in the upper surface wall 10 of the connection tool 100). An example is shown, but the present invention is not limited to this. You may make it fasten in at least one place. As the number of locations to be fastened increases, the force for preventing the skidding between the connecting device 100 and the base member 210 increases.

  Further, as shown in FIG. 8, in order to fix the connecting device 100 and the base member 210, three linear lengths of the four straight long holes 11 a to 11 d formed in the upper surface wall 10 of the connecting device 100. When using a hole, you may selectively use linear long hole 11a, 11b, 11d among four linear long holes 11a-11d, and among four linear long holes 11a-11d, you may use selectively. The straight elongated holes 11a, 11c, and 11d may be selectively used. Of the linear elongated holes 11b and 11c, the one having a wider margin for absorbing the positional deviation between the base member 210 and the support pile 201 may be selectively used.

  In the example illustrated in FIG. 8, the example in which the number of linear long holes formed at the end of the base member 210 is two is illustrated, but the present invention is not limited to this. The number of linear long holes formed at the end of the base member 210 may be one, or three or more.

[When there is no misalignment between the support pile 201 and the base member 210]
FIG. 9 is a view for explaining a state in which the support pile 201 and the base member 210 are connected by the connecting device 100, and is shown in the horizontal direction of the support pile 201 and the base member 210 (that is, shown in FIG. 2A). The case where there is no position shift in any direction of X direction and Y direction is shown.

  In this case, in a state where the base member 210 and the support pile 201 are connected by the connecting device 100, the longitudinal center line C0 of the connecting device 100 and the lengths of the linear long holes 210a and 210b formed in the base member 210. The direction center line B0 coincides. Accordingly, there is no displacement in the Y direction between the connecting device 100 and the base member 210.

  Further, the center line C1 in the direction orthogonal to the longitudinal direction of the connecting device 100 and the center line B1 orthogonal to the longitudinal direction of the linear elongated holes 210a and 210b formed in the base member 210 coincide with each other. Accordingly, there is no displacement in the X direction between the connecting device 100 and the base member 210.

  FIG. 10 is a diagram for explaining a state in which the support pile and the base member are connected by the connecting device, and shows a case where there is no positional deviation in the rotation direction between the support pile and the base member.

  In this case, in a state where the base member 210 and the support pile 201 are connected by the connecting tool 100, the reference position S0 in the rotational direction of the pile head 201b is the center line in the longitudinal direction of the connecting tool 100 as shown in FIG. It will match C0. Therefore, the margin for absorbing the misalignment of the arc-shaped long hole 21 formed in the bottom wall 20 of the connecting device 100 and the arc-shaped long hole 212 formed in the pile head 201b of the support pile 201 is completely used. Without this, the support pile 201 can be fixed to the connecting device 100.

[When there is misalignment between the support pile 201 and the base member 210]
(Position misalignment in rotation direction)
FIG. 11 is a diagram for explaining a case where a displacement in the rotation direction between the support pile and the base member occurs.

  For example, when the support pile 201 is screwed, the rotation angle of the support pile 201 is only an angle K1 with respect to the central axis C0 in the longitudinal direction of the connecting device 100 (the direction of the central axis B0 parallel to the longitudinal direction of the base member 210). In the case of displacement, the bolts Bt of the fastening member T1 are connected to the arc-shaped long holes 212 of the pile head 201b and the arc-shaped long holes 21a, 21b formed in the bottom wall 20a of the connecting device 100 overlapping the arc-shaped long holes 212. The deviation in the rotation direction can be absorbed.

  In addition, since the circular arc long hole is arrange | positioned at the 60 degree space | interval in the pile head 201b of the support pile 201, when the shift | offset | difference of 60 degree | times or more occurred, the shift | offset | difference from 0 degree to 60 degree | times occurred. As in the case, the displacement can be absorbed.

(Position shift in the linear direction (X direction))
FIG. 12 is a diagram for explaining a case where a displacement in the linear direction (X direction) between the support pile and the base member occurs. FIGS. 12 (a) and 12 (b) illustrate the direction of displacement and The case where the deviation | shift amount differs is shown.

  For example, as shown in FIG. 12A, when the base member 210 is fixed to the connecting device 100 fixed to the support pile 201, the X position displacement between the support pile 201 and the base member 210 (position shift amount E0a). Is generated, the reference position (center axis B1) in the X direction of the base member 210 and the center axis C1 of the upper surface wall 10 of the connecting device 100 are shifted by the positional deviation amount E0a. By attaching the fastening member T2 to the linear elongated hole 11 and the linear elongated holes 210a and 210b of the base member 210, the positional deviation in the X direction can be absorbed.

  Further, in the case where a displacement (position displacement amount E0b) between the support pile 201 and the base member 210 occurs in the opposite direction to the case shown in FIG. In a state where the reference position (center axis B1) and the center axis C1 of the upper surface wall 10 of the connecting device 100 are shifted by the positional deviation amount E0b, the linear elongated hole 11 of the upper surface wall 10 and the linear elongated hole of the base member 210 By attaching the fastening member T2 to 210a and 210b, the positional deviation in the X direction can be absorbed.

(Linear misalignment (Y direction))
FIG. 13 is a diagram for explaining a case where a displacement in the linear direction (Y direction) between the support pile and the base member occurs. FIGS. 13 (a) and 13 (b) show the direction of displacement and The case where the deviation | shift amount differs is shown.

  For example, as shown in FIG. 13A, when the base member 210 is fixed to the connecting device 100 fixed to the support pile 201, the Y position shift (position shift amount E <b> 1 a) between the support pile 201 and the base member 210. Is generated, the reference position (center axis B0) in the Y direction of the base member 210 and the center axis C0 of the upper surface wall 10 of the connecting device 100 are shifted by the positional deviation amount E1a. By attaching the fastening member T2 to the linear elongated hole 11 and the linear elongated holes 210a and 210b of the base member 210, the positional deviation in the Y direction can be absorbed.

  Further, in the case where a displacement (position displacement E1b) between the support pile 201 and the base member 210 occurs in the opposite direction to that shown in FIG. 13A, the Y direction of the base member 210 is the same as described above. In a state where the reference position (center axis B0) and the center axis C0 of the upper surface wall 10 of the connecting device 100 are shifted by the positional displacement amount E1b, the linear elongated hole 11 of the upper surface wall 10 and the linear elongated hole of the base member 210 By attaching the fastening member T2 to 210a and 210b, the positional deviation in the Y direction can be absorbed.

  Next, the function and effect of the first embodiment will be described.

  In the connection structure 100 a of the first embodiment, the first member 210 and the second member 201 are connected by the connection tool 100. The connecting device 100 includes a first fixing portion 10 fixed to the first member 210 by the first fastening member T2, and a second fixing portion fixed to the second member 201 by the second fastening member T1. 20, and a positional deviation in a first direction in a plane perpendicular to the axis of the second member 201 between the two members and a positional deviation in a second direction intersecting the first direction are The relative displacement between the position of the fixed portion 10 and the position of the first member 210 is absorbed, and the positional deviation in the rotational direction around the axis of the second member 201 between the two members is second. This is absorbed by relatively adjusting the position of the fixed portion 20 and the position of the second member 201.

  Thereby, the X-direction and Y-direction misalignment generated between the base member 210 and the support pile 201 and the rotational misalignment generated between the base member 210 and the support pile 201 are absorbed independently. There is an effect that can be done.

  In this way, by adjusting the deviation between the upper surface wall 10 of the coupling device 100 and the base member 210, only the positional deviation in the X direction and the Y direction is absorbed, so that the linear length of the upper surface wall 10 of the coupling device 100 is absorbed. By making the hole and the straight elongated hole of the base material orthogonal, the length of the elongated hole required for adjusting the constant deviation can be minimized.

  Further, since the adjustment of the deviation between the bottom wall 20a of the connecting device and the support pile 201 only absorbs the deviation in the rotation direction, the connecting tool and the pile head flat plate member 201b have an arcuate length necessary for adjusting the displacement. The length of the hole can be minimized.

  Further, in the connecting device 100 of the first embodiment, since the reinforcing walls 41 and 42 are provided between the top wall 10 and the bottom walls 20a and 20b, the top wall 10 will be deformed by a load from the base member 210. Even so, the upper ends of the reinforcing walls 41 and 42 can come into contact with the lower surface of the upper surface wall 10 to prevent this deformation.

  Further, the connecting device 100 is configured to bend the pressed metal flat plate member after performing press processing such as forming a straight long hole and an arc long hole in one rectangular metal flat plate member, for example. Since it is produced by processing, it can be manufactured by simple processing of a steel plate, and the manufacturing cost can be kept low.
