Moreover, in the present specification, the objects (the solar panel P, the interposing members B, C ₁ , C ₂ , 41, 42, the tool, etc.) transported by the transport carriage 3 may be It shall be called "conveyance object". Furthermore, the above-mentioned “predetermined position (that is, the position where the solar panel P or the like is conveyed in the conveyance step S4)” is a position on the first gantry main body 1 and along the first direction x. It is a position. In particular,
-The position where the solar panel P is fixed,
-It is a position near the position which fixes solar panel P. As shown in FIG. Furthermore, although it is necessary to carry out the rack placement step S1, the transport carriage setting step S2, the transport step S4, and the fixing step S5 in that order, the loading step S3 is the transport step S4. It may be implemented at any timing before implementation. For example,
The loading step S3 → the rack placement step S1 → the transport carriage setting step S2
-The rack arrangement process S1 → the loading process S3 → the transport carriage setting process S2
The mount arrangement step S1 → the transport carriage set step S2 → the loading step S3
It may be implemented in any order.

  According to the present invention, since the transportation of the solar panel P and the like is performed using the first gantry body 1 itself, temporary rails are laid or removed in addition to the gantry body. There is no need, and work time and cost can be reduced.

By the way, it is necessary for the first wheel described above to roll along the first direction x on the surface of the first gantry body 1 without falling off from the surface of the first gantry body 1, but for that purpose As a method
A method of arranging a plurality of first wheels so as to surround the first gantry body 1, as exemplified by reference numerals 321A, 321B, and 321C in FIG. 3;
As illustrated in FIG. 4, the first gantry body 1 is formed with a guide groove portion 11 along the first direction x, and the transport carriage 3 is movable in the first direction x. The insertion member 333 to be inserted into the guide groove portion 11 is disposed, and in the conveying step S4, a method of moving the conveyance carriage 3 in the first direction x in a state where the insertion member 333 is inserted into the guide groove portion 11 It can be mentioned. By adopting these methods, it is possible to prevent the first wheel from falling off the surface of the first gantry main body 1. Here, although the insertion member 333 illustrated in FIG. 4 is a substantially plate-like member suspended downward from the bogie main body 301, as illustrated by a symbol 341a in FIG. It may be a flange portion).

Moreover, the above-mentioned guide groove part 11 may be made to utilize not only in order to prevent drop-off | omission of the said conveyance trolley 3, but also for fixation of the said solar panel P. FIG. For example, as illustrated by reference numeral 11 in FIG.
A slit-like narrow portion 11a opened in the upper surface 1a of the first gantry body 1,
A wide portion 11b formed below the narrow portion 11a so as to be wider than the narrow portion 11a and in communication with the narrow portion 11a;
As shown in FIG. 6 (d), a bolt (hereinafter referred to as “mounting bolt”) for fixing the solar panel P and the interposing members B and C ₁ is formed by The screw portion 41a and the flange portion 41b extending in a direction substantially orthogonal to the screw portion 41a may be formed to have a substantially T shape. The threaded portion 41a and the flange portion 41b have a diameter (width) smaller than the width w1 of the narrow portion 11a, and the length w3 of the flange portion 41b is larger than the width w2 of the wide portion 11b. When the mounting bolt 41 supports (fixes) the solar panel P so as to be shorter than the width w1 of the narrow portion 11a, the flange portion 41b is accommodated in the wide portion 11b. It is preferable to arrange so that a part (upper end portion) of the screw portion 41a may project upward through the narrow portion 11a.

  When the guide groove portion 11 having the shape as described above is formed in the first gantry body 1, the mounting bolt 41 can be attached using the guide groove portion 11. Therefore, it is not necessary to drill holes for embedding one by one like the anchor bolt 103 illustrated in FIG. 10, and the installation work of the mounting bolt 41 can be saved by that much. When a bolt with a large head (that is, a bolt whose head width is larger than the width w1 of the narrow portion 11a) is used as a mounting bolt, such as a hexagonal bolt, the end face of the first gantry body 1 It is necessary to open the narrow portion 11a and the wide portion 11b in the (end face in the length direction x) and insert the bolt from the opening, but in the case of the mounting bolt 41, the screw portion 41a The mounting bolt 41 is inserted from the end face opening of the narrow portion 11a and the wide portion 11b because the diameter of the flange 41b and the width of the flange portion 41b are set smaller than the width of the narrow portion 11a. Even if it does not come, the mounting bolt 41 can be inserted into the narrow portion 11a at the position where it is desired to be mounted, and the mounting operation can be simplified. Furthermore, since the position (position in the horizontal direction) of the mounting bolt 41 can be adjusted in the narrow portion 11a and the wide portion 11b, the mounting bolt 41 is disposed at an appropriate position to be a solar panel P can be fixed firmly. Furthermore, since the mounting bolt 41 is detachably mounted to the first gantry main body 1, replacement of another mounting bolt having a different length is also relatively performed in the event of ground subsidence or the like. It is easy.

By the way, you may use the mounting bolt 42 which is illustrated to FIG. 7 (a) (b) instead of the mounting bolt 41 mentioned above. The mounting bolt 42 is formed by a threaded portion 42a and a flange portion 42b extending in a direction substantially orthogonal to the threaded portion 42a, and the flange portion 42b has a threaded groove formed on its inner surface. It has a through hole (screw hole), and the screw portion 42a is configured to penetrate the flange portion 42b (in a state of being screwed to the flange portion 42b). The screw portion 42a and the flange portion 42b have a diameter (width) smaller than the width w1 of the narrow portion 11a, and the length w4 of the flange portion 42b is larger than the width w2 of the wide portion 11b. It is set to be shorter than the width w1 of the narrow portion 11a. When the mounting bolt 42 supports the solar panel P, the flange portion 42b is accommodated in the wide portion 11b and a part (upper end portion) of the screw portion 42a is the narrow portion 11a. It is disposed to project upward through the When such a mounting bolt 42 is used, the amount of protrusion of the screw portion 42a (the amount of protrusion from the upper surface of the first gantry body 1) can be adjusted to avoid interference with the solar panel P or the like. it can. The mounting bolts 41 and 42 may be transported by the transport carriage 3 in a state of being attached to the column members C ₁ and C ₂ and the bracket B. In that case, the mounting bolts 41 and 42 may be transported without being inserted into the guide groove portion 11, and may be fitted into the guide groove portion 11 at a position where the solar panel P is fixed.

On the other hand, the solar panel mount stand device according to the present invention is for installing a solar panel, and as illustrated in FIGS. 1 (a) and 1 (b),

Is equipped. The transport carriage 3 may be provided with a carriage main body 301 which is a portion on which the transported object is placed, and the first wheel 311 may be rotatably supported by the carriage main body 301. Further, in the first gantry main body 1, a guide groove portion 11 along the first direction x is formed, and in the transport carriage 3, an insertion member 333 inserted into the guide groove portion 11 as illustrated in FIG. Are arranged so that the transport carriage 3 can be moved in the first direction x without falling off the first gantry body 1 based on the insertion member 333 being inserted into the guide groove portion 11. Good. In addition, although the insertion member 333 illustrated in FIG. 4 is a substantially plate-shaped member suspended downward from the trolley | bogie main body 301, as it illustrates with the code | symbol 341a in FIG. Part).

By the way, the number of the gantry bodies mentioned above may be one, and the transported object may be transported or the solar panel P may be fixed by the one gantry body, as shown in FIG. As illustrated in Fig. 2, the object to be transported may be transported by the two gantry bodies 1 and 2, and the solar panel P may be fixed. That is, the solar panel mounting apparatus K is provided with another mounting main body (hereinafter, referred to as “second mounting main body”) 2 disposed so as to be substantially parallel to the first mounting main body 1. The transport carriage 3
A carriage main body 302 which is a portion on which the transported object is placed;
-At least one wheel (second wheel) 312 rotatably supported by the carriage body 302 and arranged to roll in the first direction x on the surface of the second gantry body 2;
It is preferable that the carriage main body 301 and the carriage main body 302 be connected. In such a case, the transported object can be transported stably. Further, a play portion 303 is interposed between the first wheel 311 and the second wheel 312 (that is, between the carriage main body 301 and the carriage main body 302), and those wheels 311, It may be configured to allow relative movement within a predetermined range of 312. In such a case, even if the first gantry main body 1 and the second gantry main body 2 are not strictly parallel, the error in the play portion 303 (the first gantry main body 1 and the second gantry main body It is possible to absorb the relative positional deviation with 2), and the transported object can be transported stably. In addition, it is good for such a play part 303 to use a well-known material (for example, resin) which is rich in a certain degree of flexibility and elasticity. Further, as shown in FIG. 1 (b), similarly to the first gantry main body 1, it is preferable to form a guide groove 21 along the first direction x in the second gantry main body 2 as well. The guide groove portion 21 may be configured by the narrow portion 21a and the wide portion 21b. Furthermore, an insertion member (not shown) inserted in the guide groove portion 21 is disposed in the conveyance carriage 3, and the conveyance carriage 3 is based on the insertion member being inserted in the guide groove portion 21. It is good to constitute so that it can move to the 1st direction x, without falling off from the 2nd above-mentioned stand body 2.

  That is, the first gantry main body 1 and the second gantry main body 2 are arranged in the gantry arrangement step S1 described above, and in the transport carriage setting step S2, the first wheel 311 is on the surface of the first gantry main body 1 The transport carriage 3 may be set such that the second wheel 312 rolls on the surface of the second gantry main body 2 while

  In the example shown in FIGS. 1 (a) and 1 (b), the number of gantry bodies is two. However, the number is not limited to this, and may be three or more.

In addition, an example of a mode that many solar panels P are arrange | positioned is illustrated in FIG.9 (a) and (b). In these figures, the solar panels P are placed in a state of being assembled as a solar panel array P _A, each of the solar panels array P _A is the first frame body via the pillar member C _1, C ₂ 61 and 71 and the second gantry main bodies 62 and 72. In the example shown in FIGS. 9 (a) and 9 (b), the gantry body 61 is extended in the east-west direction, but of course the present invention is not limited to this. You may do so.

By the way, as illustrated in FIG. 9B, when making the heights of the first gantry main body 71 and the second gantry main body 71 the same, two types of pillar members C ₁ and C ₂ having different lengths are used. as was interposed between the solar panel array P _a and the gantry body 71, 72 it is sufficient to tilt the solar panel array P _a, but illustrated in FIG. 9 (a), one of the gantry body 61 may be higher than the other gantry body 62 (ie, h ₁₂ > h ₂ ). In the latter case (that is, when one gantry body 61 is made higher than the other gantry body 62), the short column member C ₁ can be used for the column member, and the cost can be reduced accordingly. In the example shown in FIG. 1 (b), the pillar member C ₁ is is fixed via a bracket B of L-shaped cross section in each frame body, of course not limited to this, other shapes it may be used bracket, or may be fixed to the pillar member C ₁ without such brackets directly to each frame body. Further, it may be directly fixed to the frame body by the mounting bolt 41 and / or 42 the solar panels P and solar panel array P _A without passing through such a column member C _1.

By the way, in order to support the solar panel P stably, the width of each gantry body (that is, the width in the y direction) should be wide. Further, in order to reduce the amount of use of the column members C ₁ and C ₂ to reduce the cost, it is better to increase the height of the gantry body. However, when the width or height of the gantry body is increased, the amount of concrete used increases. Therefore, it is preferable to make the wide portion 11 b as large as possible (that is, as large as the cover thickness of the reinforcing bar R can be secured) and to make the gantry body into a hollow structure. In such a case, the amount of concrete used for the gantry body can be reduced, and the construction cost can be reduced accordingly.
