Description

  The present invention relates to an attachment device, and more particularly to an attachment device for attaching a first member (for example, equipment such as a solar cell panel) to a second member (for example, a support such as a spiral pile).

  Conventionally, some photovoltaic power generation systems have solar cell panels installed on the ground. In such a solar power generation system, the solar cell panel is fixed on a concrete foundation laid on the ground or fixed on a steel pipe pile driven into the ground, so that the solar cell panel is installed on the ground. .

  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 steel pipe piles are used, compared with the case where concrete foundations are used, embedding and removal of steel pipe piles does not require much effort, but it is difficult to accurately determine the position of steel pipe piles. Because when steel pipe piles are driven into the ground, sufficient strength is required to support the solar cell panel mount, so it is necessary to drive steel pipe piles deep into the ground, and when steel pipe piles hit stones and gravel, This is because the axis of the steel pipe pile may be displaced.

  Therefore, conventionally, by using a spiral pile that is more difficult to pull out than a tubular steel pipe pile as a support pile of the solar cell panel, the length of the support pile is shortened to suppress positional deviation, and further, the solar cell panel The position difference of the spiral pile is absorbed by using a bolt insertion hole for connecting the mount and the spiral pile as a long hole (bolt insertion long hole).

  However, if the spiral pile is displaced in the direction perpendicular to the longitudinal direction of the bolt insertion long hole of the frame with respect to the frame, a bolt for connecting the frame to the spiral pile is inserted into the bolt insertion long hole of the frame. I can't do that.

  By the way, as a mounting tool for mounting a structure on a steel pile, a tool that can adjust the positional deviation between the pile and the structure in two orthogonal directions has been used. By using the panel gantry to attach it to the spiral pile, it is possible to absorb the displacement of the gantry and the spiral pile in the horizontal plane.

  FIG. 16 is a diagram for explaining the mounting tool (connection block) disclosed in Patent Document 1, FIG. 16 (a) shows a connection structure between a steel pipe pile and a solar cell panel, and FIG. The structure of a connection block is shown.

  In the joining structure 21, a gantry 22 for supporting a large number of solar cell panels (not shown) is supported by a steel pipe pile 23 via a support frame 25, a receiving portion 20 and a connection block 24. Here, the steel pipe pile 23 is embedded in the ground.

  The connection block 24 has a pair of upper and lower opposing upper and lower plate 24b and 24a, and a pair of opposing side surfaces formed between the plates, and bolts for fixing the steel pipe pile 23 to the lower plate 24a. Are formed, and the second long hole 26 extending in the direction (X direction) orthogonal to the longitudinal direction (Y direction) of the first long hole is formed in the upper surface plate 24b. . The second long hole 26 is a bolt insertion hole into which a bolt for fixing the receiving portion 20 to the connection block 24 is inserted.

  By using such a connection block, the displacement of the spiral pile with respect to the solar cell panel mount can be absorbed both in the longitudinal direction of the mount and in the direction orthogonal thereto.

  However, in the mounting tool disclosed in Patent Document 1, the resistance when the axial tensile force or compressive force of the spiral pile is applied to the mounting tool is not taken into consideration. When a large wind pressure is applied or a large load is applied to the fixture due to an earthquake or the like, the fixture may be deformed or damaged by the axial force of the spiral pile acting on the fixture.

The connecting member 100 has a bottom surface portion 110 fixed to the spiral pile 201 and a pair of gantry mounting portions 120a and 120b facing each other for mounting the gantry of the solar cell panel. The bottom surface part 110 is formed integrally with these gantry mounting parts between the pair of gantry mounting parts 120a and 120b. However, the connecting member 100 is not limited to one in which the bottom surface portion 110 and the pair of gantry mounting portions 120a and 120b are integrally formed.

However, the insertion hole is not limited to the arcuate base mounting long holes Hfa and Hfb, and may be a straight long hole or a round hole. Further, the shapes of the holes (round holes, straight long holes, and arc long holes) for attaching the pedestals of the upper surface flat portions 121a and 121b are the holes of the connecting member bottom surface portion 110 for fixing the piles. The shape (round hole and straight long hole) may be combined in any way, and here, the combination of the three shapes of the hole for attaching the gantry and the two shapes of the hole for fixing the pile is: There are 6 (= 3 × 2) ways.

Here, the deformation restricting member 10 is not limited to the one in which the pile fixing long hole Hp is formed in the bottom surface portion 11, and the deformation restricting member 10 is replaced with the pile fixing long hole Hp in the bottom surface portion 11. It is also possible to form a round hole for fixing to the spiral pile.

  In the mounting device 1 having such a structure, when the deformation regulating member 10 and the connecting member 100 are fixed to the spiral pile, the inclined side portions 12a2 and 12b2 of the deformation regulating member 10 are inclined to the side surfaces of the gantry mounting portions 120a and 120b. Similarly, the inclined side portions 13a2 and 13b2 of the deformation restricting member 10 abut against the surfaces 122a1 and 122b1 of the side inclined portions 122a and 122b of the gantry mounting portions 120a and 120b, respectively, in contact with the surfaces 122a1 and 122b1 of the portions 122a and 122b. Touch. Thereby, the deformation restricting member 10 is arranged such that the pair of gantry mounting parts 120a and 120b approach each other by the external force in the axial direction Ax1 of the spiral pile 201, that is, the side inclined parts 122a of the pair of gantry mounting parts 120a and 120b and The deformation of the connecting member 100 is restricted so that the interval between the upper end portions of 122b is narrowed.

  When the deformation regulating member 10 and the connecting member 100 are fixed to the spiral pile, the hook portions 12a1, 12b1, 13a1, and 13b1 pass through the engagement holes 122a5, 122b5, 122a4, and 122b4 of the side inclined portions 122a and 122b. The abutting surfaces 122a2 and 122b2 are in contact with the side inclined surface. Thereby, the deformation restricting member 10 is arranged so that the pair of gantry mounting parts 120a and 120b move away by the external force in the axial direction Ax2 of the spiral pile 201, that is, the side inclined parts 122a of the pair of gantry mounting parts 120a and 120b and The deformation of the connecting member 100 is restricted so that the interval between the upper end portions of 122b is widened.

  In addition, when the deformation restricting member 10 and the connecting member 100 are fixed to the spiral pile, the attachment device 1 is configured such that the bottom surface portion 11 of the deformation restricting member 10 is connected to the pair of mount mounting portions 120a and 120b. The upper end of the side surface portions 12 and 13 of the deformation regulating member 10 is positioned on the bottom surface portion 110 and is positioned below the upper surface flat portions 121a and 121b of the gantry mounting portions 120a and 120b of the connecting member 100. ing.

  The connecting member 100 is formed by integrally forming the connecting member bottom surface portion 110 and the gantry mounting portions 120a and 120b by pressing a metal plate. Similarly, the deformation restriction member 10 is also formed by integrally forming the bottom surface portion 11 of the deformation restriction member 10 and the side surface portions 12 and 13 of the pair of deformation restriction members 10 by pressing a metal plate. Here, each of the connecting member 100 and the deformation regulating member 10 is formed by pressing a steel plate and is galvanized. However, the constituent material of the connecting member 100 and the deformation regulating member 10 is not limited to the steel plate, and may be a stainless steel plate.

  Next, the spiral pile to which the attachment device 1 of Embodiment 1 is attached will be specifically described.

  In the first embodiment, as shown in FIGS. 5A and 12B, the spiral pile 201 includes a spiral pile main body 201a (for example, metal) embedded in the underground Ug and the upper end of the spiral pile main body 201a. And a flat spiral pile head 201b attached by welding or the like. In addition, the cross-sectional structure of the spiral pile 201 has a linear shape as shown in FIG.

  Here, the spiral pile main body 201a is formed by twisting a strip-shaped metal plate. The spiral pile head 201b is formed by pressing a metal plate. The spiral pile head 201b is formed with a bolt insertion long hole 201b1 into which an attachment bolt (not shown) for attaching the attachment device 1 to the spiral pile 201 is inserted. A bolt housing notch 201a1 for housing the head of the mounting bolt is formed at the center of the upper end of the spiral embedding portion 201a.

  In the spiral pile 201 having such a configuration, the anticorrosion treatment for the spiral pile 201 can be performed in a state where no bolt is attached, and the screw thread of the bolt can be prevented from being clogged by the anticorrosion treatment.

  However, the spiral pile 201 to which the attachment device 1 is attached is not necessarily limited to the one including the structure shown in FIG. For example, the spiral pile 201 may have a structure shown in FIG.

  The spiral pile 301 has a metal spiral pile main body 301a embedded in the ground, and a bolt 301b attached to a bolt receiving cut-in portion 301a1 formed at the upper end of the spiral pile main body 301a by welding. . Similar to the spiral pile 201 shown in FIG. 5A, the spiral pile body 301a is formed by twisting a band-shaped metal plate. Moreover, the cross-sectional shape of the spiral pile 301 is also a linear shape like the cross-sectional shape of the spiral pile 201 as shown in FIG.5 (d).

  In the spiral pile 301 having such a configuration, the structure can be simplified.

  Furthermore, spiral piles 201 and 301 shown in FIG. 5 are formed by twisting a spiral pile main body with a strip metal plate, and the cross-sectional structure is linear, but the structure of the spiral pile main body is limited to this. For example, a cross shape or a three-pronged shape may be used, and other spiral piles having different cross-sectional structures will be specifically described below.

  FIG. 6 is a diagram for explaining a configuration example of a spiral pile to which the attachment device according to Embodiment 1 of the present invention is attached, and a cross-sectional structure of three spiral piles having different cross-sectional structures of the spiral pile body (FIG. 6B). 6 (d), 6 (f)) and cross-sectional structures (FIGS. 6 (a), 6 (c), 6 (e)) of the constituent members of the spiral pile are shown.

  For example, the spiral pile 401 shown in FIG. 6 (b) is a combination of two folding members 411 (see FIG. 6 (a)) obtained by bending a belt-like metal plate at a right angle with the center line in the longitudinal direction as a fold. .

  The spiral pile 401 overlaps the ridge line portions of two bending members 411a and 411b having the same structure as the bending member 411, and is along a portion (6B portion in FIG. 6B) where the ridge line portions are overlapped. These bending members are obtained by twisting at least partially with the bending members 411a and 411b welded.

  Further, the number of bending members to be combined for creating the spiral pile is not limited to two. For example, as shown in FIG. 6 (d), the number of bending members may be four or as shown in FIG. 6 (f). Good.

  For example, the spiral pile 501 shown in FIG. 6 (d) is a combination of four folding members 511 (see FIG. 6 (c)) obtained by bending a belt-like metal plate at a right angle with the center line in the longitudinal direction as a fold. .

  The spiral pile 501 overlaps the ridge line portions of the four bending members 511a to 511d having the same structure as the bending member 511, and at least partially connects the adjacent bending members along the end portions of these bending members. It is obtained by performing twisting in a state in which these bending members 511a to 511d are further welded.

  Further, the spiral pile 601 shown in FIG. 6 (f) is a folded member 611 (FIG. 6) in which the band-shaped metal plate is folded so that the center line in the longitudinal direction is a crease and the angle formed by the flat plate portions on both sides of the center line is 120 degrees. 6 (e)) is combined.

  The spiral pile 601 overlaps the ridge lines of three bending members 611a to 611c having the same structure as the bending member 611, and at least partially welds the adjacent bending members along the end portions of these bending members. In addition, these bending members 611a to 611c are obtained by being twisted in a welded state.

  Next, with reference to FIGS. 7 to 11, a method for attaching the solar cell panel base 202, particularly the base member 210 of the base 202 to the spiral pile, using the mounting tool 1 of the first embodiment will be described.

  First, the spiral pile 201 is disposed on the ground G at a position where the spiral pile 201 is to be driven (FIG. 7A), and the spiral pile 201 is driven against the ground G (FIG. 7B).

  Thereafter, as shown in FIGS. 8 and 9, the fixture 1 is fixed to the spiral pile 201.

  First, as shown in FIG. 8A, the bolt 131 is passed through the bolt mounting hole 201b1 of the spiral pile head 201b.

  Specifically, as shown in FIG. 8B, the bolt mounting hole 201b1 is a long hole, and is formed at a position offset to one side from the center of the spiral pile head 201b. Therefore, as shown in FIG. 8C, the bolt 131 can be mounted in the bolt mounting hole 201b1 without interfering with the spiral pile main body 201a at the end on one end side (left side of the drawing) of the bolt mounting hole 201b1.

  When the bolt 131 is moved to the center of the spiral pile head 201b after the bolt 131 is mounted in the bolt mounting hole 201b1 in this way, the bolt 131 is inserted into the bolt housing notch 201a1 formed at the upper end of the spiral pile 201. It is accommodated (FIG. 8D). As described above, in the state where the bolt 131 is accommodated in the bolt accommodating notch 201a1, the rotation of the bolt 131 is regulated by the inner surface of the bolt accommodating notch 201a1 and the head of the bolt 131 coming into contact. It has become.

  After mounting the bolt 131 on the spiral pile head 201b of the spiral pile 201 in this way, as shown in FIG. 9 (a), the bolt 1 is fitted with the deformation regulating member 10 fitted to the connecting member 100. Attach to 131. Thus, when mounting the fixture 1 on the spiral pile head 201b, the longitudinal direction of the fixture 1 is generally the direction in which the base member (C channel steel) 210 of the gantry 202 is attached (the direction in which the C channel steel extends). ). FIG.9 (b) has shown the state which mounted the fixture 1 on the spiral pile head 201b. In this state, the nut 131 is attached to the bolt 131, and the connecting member 100 and the deformation regulating member 10 are fastened to the spiral pile head 201b, thereby fixing the attachment device 1 to the spiral pile 201 (FIG. 9 (c). )).

  Thereafter, the base member (C channel steel) 210 of the solar cell panel mount 202 is mounted on the fixture 1 as shown in FIG.

  Specifically, the frame mounting long holes Hfa and Hfb formed in the frame mounting portions 120a and 120b of the connecting member 100 and the bolt insertion long holes 211 formed in the base member 210 intersect with each other. The bolts 141 and 143 are attached, the nuts 142 and 144 are attached to the bolts 141 and 143, and the base member 210 is fastened to the gantry mounting portions 120a and 120b of the connecting member 100 (FIG. 10A).

  At the construction site of the solar cell panel, as shown in FIG. 10 (b), the longitudinal direction of the attached base member 210 and the longitudinal direction of the attachment device 1 are not necessarily coincident, but the longitudinal direction of these members is not the same. If the displacement is about the construction error as shown in FIG. 10C, the displacement can be absorbed by the arcuate frame attachment long holes Hfa and Hfb formed in the frame mounting portions 120a and 120b.

  Further, in the actual construction of the solar cell panel, the position of the spiral pile 201 is in the lateral direction (for example, the longitudinal direction of the base member 210) and the longitudinal direction (for example, the direction orthogonal to the longitudinal direction of the base member 210) ) May deviate by about ± 50 mm. Even in such a case, the displacement between the base member 210 and the spiral pile 201 in the longitudinal direction of the base member 210 can be adjusted by the bolt insertion long hole 211 formed in the base member 210. Further, the deviation between the base member 210 and the spiral pile 201 in the direction perpendicular to the longitudinal direction of the base member 210 is adjusted by the pile fixing long hole Hpf of the connecting member 100 and the pile fixing long hole Hp of the deformation regulating member 10. In addition, this displacement is caused by the cross between arcuate base mounting holes Hfa and Hfb formed in the base mounting parts 120a and 120b and the bolt insertion long hole 211 formed in the base member 210. It can be adjusted within the range.

  As a result, as shown in FIG. 11, the base member 210 of the gantry 202 can be fixed to the spiral pile head 201b of the spiral pile 201 using the fixture 1 (FIGS. 11A and 11B). )). In FIG. 11, 132b, 142b, 144b are spring washers, and 132a, 141a, 142a, 143a, 144a are plain washers.

  Thereafter, by attaching a plurality of solar battery panels S on the base member 210 through, for example, the support frame 220, the solar power generation system 100a can be installed as shown in FIG.

  In the photovoltaic power generation system 100a shown in FIG. 12A, the base member 210 of the gantry 202 is fixed so as to straddle the plurality of spiral piles 201, and the plurality of solar battery panels S are attached to the gantry 202. However, the stand of the solar cell panel S may be independent for each individual solar cell panel. In this case, one mount for the spiral pile 201 is provided by the mounting tool 1 of the first embodiment. A stand for the solar panel S can also be attached.

  In this case, the arcuate base mounting slots Hfa and Hfb formed in the base mounting parts 120a and 120b can also be used to adjust the orientation of the solar cell panel S.

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

  In the first embodiment, in the fixture 1 that fixes the gantry of the solar cell panel S to the spiral pile 201, the connecting member 100 that couples the gantry of the solar cell panel to the spiral pile 201, and the axial directions Ax1 and Ax2 of the spiral pile 201 Since the deformation restricting member 10 that restricts deformation of the connecting member 100 when an external force acts on the connecting member 100 is provided, in the mounting device for fixing equipment such as a solar cell panel to the spiral pile, the axis of the spiral pile High resistance to external force in the direction can be realized. As a result, even when a large external force in the axial direction of the spiral pile is applied to the fixture due to a strong wind or an earthquake, an effect that the fixture 1 can be prevented from being deformed or damaged is obtained.

  Further, since the deformation restricting member 10 that restricts deformation of the connecting member 100 is fixed to the spiral pile 201 together with the connecting member 100, the deformation restricting member 10 is welded to the connecting member 100 or fixed by caulking. Compared with the case of fixing with a rivet, it is possible to reduce the labor of processing the mounting device 1 and to manufacture the mounting device 1 in which the deformation of the connecting member 100 is restricted at a low cost.

  In the first embodiment, the gantry mounting portions 120a and 120b of the connecting member 100 include the upper surface flat portions 121a and 121b located above the connecting member bottom surface portion 110, the upper surface flat portions 121a and 121b, and the connecting member bottom surface portion. When the deformation restricting member 10 and the connecting member 100 are fixed to the spiral pile 201, the deformation restricting member 10 includes a pair of gantry mounting portions 120a and 120b. Since the base member 210 of the gantry 202 is disposed on the upper surface flat portions 121a and 121b of the gantry mounting portions 120a and 120b, the deformation restricting member 10 is positioned below the upper surface flat portions 121a and 121b. Interference with the base member 210 can be avoided.

  Further, the upper surface flat portions 121a and 121b of the gantry mounting portions 120a and 120b have arcuate gantry mounting long holes Hfa and Hfb around the center of the long hole Hpf in the connecting member 100, and the gantry mounting portions 120a and 120b. Since it is formed as a bolt insertion hole for fastening 120b and the base member 210 of the gantry, even if the longitudinal direction of the connecting member 100 and the longitudinal direction of the base member 210 are deviated, both are fixed with a bolt and a nut. It is possible.

  Further, a displacement restriction that restricts the displacement of the upper surface flat portions 121a and 121b relative to the side surface inclined portions 122a and 122b at the boundary between the upper surface flat portions 121a and 121b and the side surface inclined portions 122a and 122b in the gantry mounting portions 120a and 120b. Since the grooves 122a3 and 122b3 are formed, when the external forces in the axial directions Ax1 and Ax2 of the spiral pile 201 act on the upper surface flat portions 121a and 121b, the upper surface flat portions 121a and 121b with respect to the side inclined portions 122a and 122b. Can be prevented from bending.

  Further, since the outer end portions of the upper surface flat portions 121a and 121b of the gantry mounting portions 120a and 120b are folded downward, the strength of the upper surface flat portions 121a and 121b in the width direction of the connecting member 100 is increased, and the upper surface flat portion is increased. It can suppress that 121a and 121b bend in the part in which the bolt nut was attached.

  In addition, the bottom portion 110 of the connecting member 100 has a long hole Hpf that can adjust the relative position of the connecting member 100 and the spiral pile 201 as an insertion hole for a bolt 131 for fixing the connecting member 100 to the spiral pile 201. A relative position between the deformation regulating member 10 and the spiral pile 201 is formed in the bottom surface portion 11 of the deformation regulating member 10 as an insertion hole for inserting a bolt 131 for fixing the deformation regulating member 10 to the spiral pile 201. Since the long hole Hp capable of adjusting the height of the base member 210 is formed, the mounting tool 1 can absorb the shift between the spiral pile 201 and the base member 210 of the gantry in the direction orthogonal to the longitudinal direction of the base member 210.

  Further, such a shift between the spiral pile 201 and the base member 210 of the gantry in the direction orthogonal to the longitudinal direction of the base member 210 is a circle formed on the upper surface flat portions 121a and 121b of the gantry mounting portions 120a and 120b. Adjustment can be made within a range where the arc-shaped gantry mounting long holes Hfa and Hfb intersect with the bolt insertion long hole 211 formed in the base member 210.

  Further, since the upper surface flat portions 121a and 121b of the gantry mounting portions 120a and 120b on which the base member 210 of the gantry 202 is mounted have a flat structure, the upper surface flat portions 121a and 121b have the gantry 202 on the upper surface flat portions 121a and 121b. The base member 210 can be placed with good stability.

  In addition, in the said Embodiment 1, the connecting member 100 deform | transforms the attachment implement 1 so that a pair of mount mounting part 120a and 120b may move away, when the external force of the axial direction Ax2 of the spiral pile 201 acts on the connecting member 100. That is, the deformation regulating member 10 regulates the deformation of the connecting member 100 so that the pair of gantry mounting portions 120a and 120b approach each other when the external force in the axial direction Ax1 of the spiral pile 201 acts on the connecting member 100. However, the attachment member 1 is deformed so that the pair of gantry mounting portions 120a and 120b move away by the external force in the axial direction Ax2 of the spiral pile 201 acting on the connection member 100. And the external force in the axial direction Ax1 of the spiral pile 201 acts on the connecting member 100. May be one which is configured to regulate the deformation restricting member 10 to the connecting member 100 so as to approach the pair of frame mounting portion 120a and 120b is one to one variant of being deformed by the.

  For example, in the connecting member 100, the gantry mounting portions 120a and 120b have a structure without the engagement holes 122a4, 122a5, 122b4 and 122b5. Further, in the deformation restricting member 10, the side surface portions 12 and 13 are hook portions 12a1, 12b1, By adopting a structure without 13a1 and 13b1, the attachment device 1 is connected so that the pair of gantry mounting portions 120a and 120b approach each other by the external force in the axial direction Ax1 of the axial direction Ax1 and the axial direction Ax2 of the spiral pile 201. The deformation of the member 100 can be restricted by the deformation restriction member 10.

  In this case, it is not necessary to provide the hooks 12a1, 12b1, 13a1, and 13b1 on the deformation restricting member 10, and the deformation restricting member 10 can have a more compact structure. For example, the mounting fixture 1 having such a structure is effective in an area where there is no possibility of generating a large force acting on the mounting fixture 1 from the upper side of the solar cell panel due to snow or the like.

  Further, in the deformation restricting member 10, the inclined side portions 12 a 2, 12 b 2, 13 a 2 and 13 b 2 are structured so as not to come into contact with the side inclined portions 122 a and 122 b of the connecting member 100. The deformation restricting member 10 can restrict the deformation of the connecting member 100 so that the pair of gantry mounting portions 120a and 120b move away by an external force in the axial direction Ax2 of the axial direction Ax1 and the axial direction Ax2. .

  In this case, the side surface portions 12 and 13 of the deformation regulating member 10 are formed from both sides of the side surface portions 12 and 13 by the inclined side portions 12 a 2, 12 b 2, 13 a 2 and 13 b 2 being in contact with the side surface inclined portions 122 a and 122 b of the connecting member 100. Since it is not compressed, the thickness of the deformation restricting member side surfaces 12 and 13 can be reduced. For example, the attachment device 1 having such a structure is effective in an area where there is no possibility of generating a large force acting on the attachment device 1 from the lower side of the solar cell panel due to a typhoon or the like.

  In the first embodiment, the attachment device includes a pair of opposed platform mounting portions provided on both sides of the bottom surface portion 110 of the connecting member 100. The portion may be provided only on one side of the connecting member bottom surface portion 110.

(Modification 1 of Embodiment 1)
FIG. 13: is a perspective view explaining the attachment instrument by which the mount mounting part was provided only in the one side of the connection member bottom face part as an attachment instrument by the modification 1 of Embodiment 1 of this invention, and the connection of an attachment instrument The member and the deformation regulating member are shown separately. In FIG. 13, the same components as those in FIG. 1 are denoted by the same reference numerals.

  The attachment device 5 according to the first modification of the first embodiment includes a connecting member 101 that connects the mount of the solar cell panel to the spiral pile, and the connecting member 101 is deformed by an external force acting on the connecting member 100 in the axial direction of the spiral pile. And a deformation restricting member 50 for restricting the operation.

  Here, the connecting member 101 has a structure obtained by removing one of the gantry mounting portions 120b in the connecting member 100 of the first embodiment. Moreover, the deformation | transformation control member 50 has a structure obtained by removing the part of the one end side of the pile fixing long hole Hp in the deformation | transformation control member 10 of Embodiment 1. FIG. Here, the bottom surface portion 51 and the side surface portions 52 and 53 of the deformation restriction member 50 correspond to the bottom surface portion 11 and the side surface portions 12 and 13 of the deformation restriction member 10 of the first embodiment, respectively. However, in the first modification of the first embodiment, only the one side surface end portions 53a and 52a of the side surface portions 53 and 52 of the deformation regulating member 50 are engaged with the engagement holes 122a4 and 122a5 of the gantry mounting portion 120a, respectively. Hook portions 53a1 and 52a1 are formed, and inclined side portions 53a2 and 52a2 extending from the respective hook portions 53a1 and 52a1 toward the deformation regulating member bottom surface portion 51 are formed.

  In the first modification of the first embodiment, the inclined side portions 53a2 and 52a2 of the deformation restricting member 50 abut on the surface of the gantry mounting portion 120a (the surface 122a1 of the side inclined portion 122a), so that the gantry mounting portion 120a is Displacement relative to the connecting member bottom surface portion 110 is restricted. Thereby, when the external force which pulls the mount mounting part 120a upward acts on the connection member 101, it can control that the connection member 101 deform | transforms.

  Further, the side surface end portions 53a and 52a of the deformation regulating member 50 are engaged with the engagement holes 122a4 and 122a5 of the gantry mounting portion 120a, so that the gantry mounting portion 120a is in contact with the bottom surface portion 110 of the connecting member 101. Displacement is restricted. Thereby, when the external force which presses the mounting base 120a downward acts on the connection member 101, it can control that the connection member 101 deform | transforms.

  In addition, in the fixture 5 by the modification 1 of the said Embodiment 1, although the connection member bottom face part 110 becomes a structure which has the linear protrusion part 111 similarly to the connection member bottom face part 110 of Embodiment 1, it is connected. The member bottom surface portion 110 may have a flat structure without a linear protrusion.

(Modification 2 of Embodiment 1)
FIG. 14 is a diagram for explaining a mounting device having a flat bottom surface portion of the connecting member as a mounting device according to the second modification of the first embodiment of the present invention. The connecting member and the deformation regulating member of the mounting device are shown separately. ing. In FIG. 14, the same components as those in FIG. 13 are denoted by the same reference numerals.

  The attachment device 5a according to the second modification of the first embodiment includes a connecting member 101a that replaces the connection member 101 of the attachment device 5 according to the first modification of the first embodiment.

  The gantry mounting portion 120c and the bottom surface portion 110a of the connecting member 101a correspond to the gantry mounting portion 120a and the bottom surface portion 110 of the connecting member 101 of the first modification of the first embodiment. However, the bottom surface portion 110a of the connecting member 101a is composed of a bottom flat plate 111a, and unlike the connecting member bottom surface portion 110 of the first modification, has a flat structure without the linear protrusion 111. Further, the height of the side inclined portion 122c of the gantry mounting portion 120c is lower than the height of the side inclined portion 122a of Modification 1 of Embodiment 1 in accordance with the flat bottom surface 110a of the connecting member 101a. doing. Thereby, also in the fixture 5a of the modification 2 which made the bottom face part 110a of the connection member 101a a flat structure, the deformation control member 50 of the same structure as the modification 1 can be used. However, in the second modified example, the heights of the side surface parts 52 and 53 of the deformation regulating member 50 may be increased instead of lowering the height of the side inclined part 122c than that of the first modified example.

  In the mounting device 5a having such a structure, the inclined side portions 53a2 and 52a2 of the deformation regulating member 50 are the surfaces of the side inclined portions 122c of the gantry mounting portion 120c, as in the mounting device 5 of the first modification of the first embodiment. The deformation of the connecting member 101a is restricted by contacting with 122c1, and the hook parts 53a1 and 52a1 pass through the engaging holes 122a5 and 122a4 of the side inclined part 122c and contact with the side inclined part back surface 122c2. The deformation of the member 101a is restricted.

  Note that, in the attachment devices according to the first and second modifications of the first embodiment, an external force that pulls the gantry mounting portion of the connecting member acts on the linking member, so that the gantry mounting portion is displaced with respect to the bottom surface portion of the connecting member.
