Description

  The present invention relates to a panel holding structure that holds various flat panels such as a photovoltaic power generation panel and a solar hot water panel in a predetermined posture.

  In recent years, interest in solar power generation systems has increased, and large-scale and small-scale solar power generation facilities have been constructed throughout Japan. Since a large number of photovoltaic power generation panels are installed in the photovoltaic power generation facilities, not only the power generation panels but also their holding structures are repeatedly examined from various aspects such as construction cost, ease of construction or durability, Various methods have been developed and implemented.

  In the conventional solar panel holding structure, as a thing relevant to this invention, there exists "the stand for solar panels" of patent document 1, for example. This "solar panel mount" is composed of a foundation frame on which the solar panel is placed and a foundation pile that supports the foundation frame with the head, and the number of foundation piles in the inclination direction of the foundation frame is one. Yes, a cane member is bridged between the foundation pile and the large pulling member of the base frame constituent member having a length extending in the inclined direction, and the joint portion of the foundation pile to the cane member, The position of at least one of the coupling portions of the large pulling member with respect to the cane member can be adjusted in the length direction of the member in which the one coupling is performed with respect to the cane member.

JP 2014-103334 A

  The "solar panel mount" described in Patent Document 1 is used when the foundation pile that has entered the ground with the head remaining on the ground is not accurately in the vertical position or the foundation pile inside the ground. Even if there is an error in the penetration depth, the foundation frame can be supported by the head of the foundation pile with an accurate inclination angle.

  On the other hand, in recent years, the number of places where solar power generation facilities are built is increasing not only on flat land, but also on mountain slopes and hills with many undulations. When constructing photovoltaic power generation facilities on slopes in mountainous areas or hills with many undulations, it is difficult to construct piles (foundation piles) in a predetermined position at a predetermined position. One of these piles may not be erected in the correct position at the designed position.

  Specifically, the pile material driving position may shift in either the east, west, south, or north direction, the longitudinal direction of the pile material may deviate diagonally from the vertical direction, or the pile material may twist around its longitudinal direction. There is. In this way, if the pile material is erected in a state where the position or posture of the pile material is shifted, a failure may occur in the connection between the pile material and other members constituting the panel holding structure, or the connection may be impossible. As a result, it may become impossible to construct a panel holding structure as designed.

  Therefore, the problem to be solved by the present invention is that the panel can be kept in the designed state even when the standing position and the standing posture of the pile material are deviated from the normal state, and the construction is also possible. The object is to provide an easy panel holding structure.

A plurality of main beams joined via a fifth screw mechanism in a state orthogonal to the transverse beam and parallel to each other at a plurality of locations on the transverse beam;
The bolt hole opened in the large beam in the second screw mechanism and the bolt hole opened in the large beam in the fourth screw mechanism are each an oval having a diameter expanded in the longitudinal direction of the large beam,
In the fourth screw mechanism, the bolt hole formed in the transverse beam is an oval having a diameter expanded in the longitudinal direction of the transverse beam.

  In the panel holding structure, it is desirable that an auxiliary member having an L-shaped cross section be interposed between the large beam and the transverse beam in the fourth screw mechanism.

  Furthermore, in the panel holding structure, in the third screw mechanism, a gusset member can be interposed between the other end portion of the brace and the pile material.

  On the other hand, between the pile material and the girder in the first screw mechanism, and between the pile material and the lower end of the brace in the third screw mechanism, twisting around the longitudinal direction of the pile material is performed. A rotation correcting member to be corrected may be interposed.

  The present invention provides a panel holding structure that can hold the panel as designed and can be easily constructed even when the standing position and posture of the pile material are shifted from the normal state. can do.

The joining position of the auxiliary member 45 to the large beam 2 can be changed along the major axis direction of the bolt hole 2g (longitudinal direction of the large beam 2).

  Since the fourth screw mechanism 40 as shown in FIG. 12 is also formed at the joint portion between the flat portion 45 c of the auxiliary member 45 and the cross beam 6, the joint position of the auxiliary member 45 with respect to the cross beam 6 is the longitudinal direction of the cross beam 6. It can be changed along the direction.

  As shown in FIGS. 1, 4, and 10, the fifth screw mechanism 50 is provided in the main beam 7 and the bolt hole 5 b provided in the horizontal beam 5 at the joint portion between the horizontal beam 5 and the main beam 7.

The bolt hole 5b of the horizontal beam 5 has an oval shape whose diameter is increased in the longitudinal direction of the horizontal beam 5, and the bolt hole 7a of the main beam 7 is circular. For this reason, the joining position of the main beam 7 with respect to the cross beam 5 can be changed along the major axis direction (longitudinal direction of the cross beam 5) of the bolt hole 5b of the cross beam 5. In addition, the 5th screw mechanism 50 in the junction part of the cross beam 6 and the main beam 7 also has the structure and function similar to the 5th screw mechanism 50 shown in FIG. 4, FIG.

  As shown in FIGS. 2 and 7, in the first screw mechanism 10, the joining position of the large beam 2 to the pile material 1 can be changed along the major axis direction of the bolt hole 1 c (longitudinal direction of the pile material 1). For this reason, when deviation occurs in the driving depth of the pile material 1, the holding height (vertical) of the large beam 2 is adjusted by adjusting the joining position of the large beam 2 with respect to the pile material 1 using the first screw mechanism 10. The holding position in the direction V) can be corrected.

  As shown in FIGS. 1, 5, and 6, the joining portion between the upper end 2 b of the girder 2 and the cross beam 5 and the joining portion between the lower end 2 c of the girder 2 and the cross beam 6 have auxiliary members 45 respectively. A four-screw mechanism 40 is formed. For this reason, the joining position of the horizontal beams 5 and 6 with respect to the large beam 2 can be changed along the longitudinal direction (east-west direction) of the horizontal beams 5 and 6. For this reason, when the placing position of the pile material 1 is shifted in the east-west direction, and the arrangement position of the large beam 2 is shifted in the east-west direction, the fourth beam mechanism 40 is used to join the horizontal beams 5, 6 to the large beam 2. By adjusting the position, it is possible to correct the position of the horizontal beams 5 and 6 in the east-west direction.

  As shown in FIGS. 5 and 6, in the fourth screw mechanism 40, the joining position of the lateral beams 5 and 6 with respect to the large beam 2 can be changed along the longitudinal direction (north-south direction) of the large beam 2. For this reason, as shown in FIG. 2, when the placement position of the beam 2 is displaced in the north direction due to the displacement of the driving position of the pile material 1, the fourth beam mechanism 40 is used to 2 is adjusted, the arrangement position of the horizontal beams 5 and 6 in the north-south direction can be corrected.

  Further, when the driving position of the pile material 1 is shifted in the south direction, if the joint position of the cross beams 5 and 6 with respect to the large beam 2 is adjusted using the fourth screw mechanism 40, the cross beams 5 and 6 are moved in the north-south direction. The arrangement position can be corrected.

  As described above, by using the fourth screw mechanism 40 to adjust the joining position of the transverse beams 5 and 6 with respect to the large beam 2, the arrangement position of the transverse beams 5 and 6 in the east-west direction can be corrected. For this reason, as shown in FIGS. 13 and 14, when the driving direction of the pile material 1 is inclined to the west direction from the virtual vertical line VL (vertical direction V) (the head 1a of the pile material 1 is inclined to the west direction). In the same manner, by using the fourth screw mechanism 40 to adjust the joining position of the transverse beams 5 and 6 with respect to the large beam 2, the arrangement position of the transverse beams 5 and 6 can be corrected to the east side.

  Even when the driving direction of the pile material 1 is shifted in the east direction (even when the head portion 1a of the pile material 1 is inclined in the east direction), the transverse beam with respect to the girder 2 is similarly utilized using the fourth screw mechanism 40. By adjusting the joining position of 5 and 6, the arrangement position of the cross beams 5 and 6 can be corrected to the west side.

  Next, as shown in FIG. 15, when the driving direction of the pile material 1 is inclined in the north direction from the virtual vertical line VL (vertical direction V) (when the head 1a of the pile material 1 is inclined in the north direction). Are a first screw mechanism 10 formed between the head 1a of the pile material 1 and the large beam 2, a second screw mechanism 20 formed on the upper end 2b side and the lower end 2c side of the large beam 2, and a brace. If the joint angle of the large beam 2 to the pile material 1 is adjusted using the third screw mechanism 30 between the lower end portions 3b, 4b of 3 and 4 and the gusset member 8, the inclination angle of the large beam 2 is designed. Can be corrected in the street.

  Moreover, when the driving direction of the pile material 1 is inclined to the south direction from the virtual vertical line VL (vertical direction V) (when the head portion 1a of the pile 1 is inclined to the north direction), the head portion 1a of the pile material 1 is used. The first screw mechanism 10 formed between the upper beam 2 and the large beam 2, the second screw mechanism 20 formed on the upper end 2b side and the lower end 2c side of the large beam 2, and the lower end portions 3b, 4b of the braces 3, 4 If the joint angle of the girder 2 to the pile material 1 is adjusted using the third screw mechanism 30 between the girder member 8 and the gusset member 8, the inclination angle of the girder 2 can be corrected as designed.

  Next, as shown in FIG. 16, when the driving position of the pile material 1 is twisted about 5 degrees around the longitudinal direction of the pile material 1, the upper end portion 2b of the girder 2 is shifted to the west side. The lower end 2c of the large beam 2 is shifted to the east side. In this case, as shown in FIGS. 17 and 18, if the fourth screw mechanism 40 at the upper end 2 b and the lower end 2 c of the large beam 2 is used to adjust the joint position with the horizontal beams 5, 6, 6 can be corrected in the east-west direction.

  As described above, when the driving posture of the pile material 1 is twisted around the longitudinal direction of the pile material 1, if the twist angle is within a range of about ± 5 from the original posture, FIG. As shown in FIG. 4, by using the fourth screw mechanism 40, it is possible to correct the displacement of the horizontal beams 5 and 6 in the east-west direction.

  On the other hand, when the twist angle of the pile material 1 exceeds ± 5 degrees, the twist can be corrected by using the rotation correction members 60 and 70 as shown in FIGS.

  Specifically, as shown in FIG. 19 and FIG. 20, bolt nuts BN are used at positions where the large beam 2 (see FIG. 2) on the head 1 a side of the pile material 1 driven in a twisted state is attached. The rotation correction member 60 is attached. As shown in FIGS. 19 and 22, the rotation correction member 70 is attached to the pile material 1 at a position where the gusset member 8 (see FIG. 2) is attached using a plurality of bolts and nuts BN.

  As shown in FIGS. 20 and 21, the rotation correction member 60 includes a flat plate-like joint portion 61 that abuts against the flat portion 1 d of the beam member 1, and two support leg portions 62 that stand upright from the joint portion 61. 63, and flat joint portions 64 and 65 extending in a direction away from the support leg portions 62 and 63, respectively. The leg length of the support leg 63 is larger than the leg length of the support leg 62, and bolt holes 61a, 64a, 65a are formed in the joints 61, 64, 65, respectively.

  As shown in FIGS. 19 to 21, when the rotation correction member 60 is fixed to the pile material 1 using the bolt and nut BN in a state where the joint portion 61 is in contact with the flat surface portion 1 d of the pile material 1, the joint portion 64, Since the surface direction of the joint surfaces 64b and 65b of 65 is parallel to the north-south direction, the bolts and nuts BN are used to fix the joint portions 64 and 65 to the joint portions 64 and 65 in a state where the large beams 2 are in contact with the joint portions 64 and 65. The longitudinal direction of the girder 2 is parallel to the north-south direction.

  As shown in FIGS. 22 and 23, the rotation correction member 70 includes a flat plate-like joint portion 71 that abuts against the flat portion 1 d of the beam member 1, and two support leg portions 72 that stand upright from the joint portion 71. 73, and flat joint portions 74 and 75 extending in directions away from the support leg portions 72 and 73, respectively. The leg length of the support leg portion 73 is larger than the leg length of the support leg portion 72, and bolt holes 71a, 74a, 75a are formed in the joint portions 71, 74, 75, respectively.

  As shown in FIGS. 19, 22, and 23, when the rotation correction member 70 is fixed to the pile material 1 using the bolt and nut BN in a state where the joint portion 71 is in contact with the flat portion 1 d of the pile material 1, Since the joining surfaces 74b and 75b of the parts 74 and 75 are parallel to the north-south direction, the lower end part 4b of the brace 4 is used with the bolt nut BN in a state where the lower end part 4b of the brace 4 is in contact with the joining part 74. If it fixes to the junction part 74, the longitudinal direction of the brace 4 will become parallel to the north-south direction. Although not shown, if the lower end 3b of the brace 3 is fixed to the joint 75 using the bolt and nut BN while the lower end 3b of the brace 3 is in contact with the joint 75, the longitudinal direction of the brace 4 Is parallel to the north-south direction.

  Thus, if the rotation correction members 60 and 70 are used, the torsion around the longitudinal direction of the beam material 1 can be corrected, and the large beam 2 and the braces 3 and 4 can be arranged as designed. In addition, if the leg length difference of the support leg parts 62 and 63 (72, 73) of the rotation correction member 60 (70) is changed, the magnitude of the twist angle of the beam member 1 can be dealt with.

  As described above, the panel holding structure 100 includes the displacement of the pile material 1 in the driving depth, the displacement in the east-west direction of the pile material 1, the displacement in the north-south direction, and the displacement in the driving direction of the pile material 1 (the pile material 1 Even if the pile material 1 is twisted around the longitudinal direction, the displacement, inclination, and twist are caused by the first screw mechanism 10 to the fifth screw. It is possible to correct using the mechanism. For this reason, the photovoltaic power generation panel 9 can be maintained in a normal state (as designed) even in a place where unevenness such as inclination, unevenness, or undulation exists on the surface of the ground Z.

  That is, the panel holding structure 100 can hold the photovoltaic power generation panel 9 in a designed state even when the standing position and the standing posture of the pile material 1 are shifted from the normal state. Moreover, since the panel holding structure 100 can be constructed by a general-purpose technique using a general-purpose member, construction is also easy.

  In addition, as shown in FIGS. 1-3, in the panel holding structure 100 of this embodiment, although the two pile materials 1 are standingly arranged in the north-south direction, the number of pile materials 1, arrangement | positioning space | interval, a horizontal beam Since the lengths of the main beams 7 and 6 are not limited, a panel holding structure having a larger scale than the panel holding structure 100 can be constructed.

  Moreover, the panel holding structure 100 demonstrated based on FIGS. 1-23 shows an example of this invention, and the panel holding structure which concerns on this invention is not limited to the panel holding structure 100 mentioned above.

  The panel holding structure of the present invention can be widely used in fields such as civil engineering construction for building solar power generation facilities, solar hot water facilities, and the like.
