Description

  The present invention relates to a gantry. In detail, it is related with the mount frame which supports a solar panel.

  Conventionally, a solar panel that generates electricity by using light energy of sunlight is known (see Patent Document 1). This solar panel is installed on a vast land with an inclination at the most efficient power generation efficiency.

In order to support such a solar panel, for example, the following mount has been proposed (see Patent Document 1).
That is, a rectangular bar on which the solar panel is mounted and a plurality of support parts that support the bar are provided.
The crosspiece is configured by combining a plurality of horizontal crosspieces extending in the column direction and a plurality of vertical crosspieces extending in the interbeam direction in a lattice shape. In addition, this beam is inclined so that the horizontal beam in the column direction is substantially horizontal and one end side of the vertical beam in the inter-beam direction is lower than the other side.

  A plurality of support portions are installed side by side on a flat site. Each support portion extends substantially vertically and has a single column made of H steel connected to the beam at the upper end, and a cross section provided across the column and extending obliquely from the lower end side of the column and connected to the beam And a pair of arms made of a hat-shaped steel material. Here, the support column and the pair of arms of each support portion are connected to one vertical rail. Thereby, a support | pillar and a pair of arm will be arrange | positioned on a straight line.

  In this gantry, since the truss is composed of the support columns and the pair of arms and one vertical residue to which these are connected, the solar panel can be stably supported.

  However, since the above-described frame requires a plurality of support portions, there is a possibility that the frame cannot be installed when the site is small and the land is large.

  An object of the present invention is to provide a pedestal that can be installed even when the site is small and uneven.

  The pedestal according to claim 1 (for example, a pedestal 1 described later) is a pedestal for supporting a solar panel (for example, a solar panel 2 described later), and has a planar shape on which the solar panel is placed. A frame portion (e.g., a frame portion 10 described later) and a single support portion (e.g., a support portion 20 described later) that extends upward from the ground surface and supports the frame portion. A plurality of beam members extending in the column direction (for example, a column member 11 described later), and a plurality of beam members (for example, a beam member 12 described later) that intersect with the column member and extend in the beam direction. The part has a columnar column (for example, column 21 described later) that protrudes from the ground surface and is connected to the frame unit, and at least two wands that extend upward from the column and are connected to the frame unit (for example, A brace 22) to be described later, and the strut, the brace and the frame The connection points (for example, connection points 13A and 13B described later) are arranged in a polygonal shape, and an annular ring (for example, a ring joint described later) is provided at a predetermined height position of the support column. 23) is attached, and the lower end of the wand is connected to the ring.

According to this invention, in each support part, a solid truss is comprised with a frame part, a support | pillar, and a cane. That is, this solid truss forms a polygonal pyramid having a ring as a top vertex and a polygon formed by a connection point between the column and the cane and the frame, and the polygonal pyramid is turned upside down. Therefore, the solar panel can be stably supported, and it can sufficiently resist not only the load in the beam-to-beam direction but also the load in all directions including the beam direction.
In addition, since the supporting portion is single, it can be installed even when the site is small and the unevenness is large.

  In the gantry according to claim 2, a plurality of through holes (for example, through holes 231 described later) are formed at predetermined intervals along the outer periphery of the ring. It is inserted and fixed to what was suitably chosen from a plurality of through holes.

  According to the present invention, since the through holes are provided at predetermined intervals along the outer periphery of the ring, the number of the canes can be freely increased or decreased by appropriately changing the connecting portion between the cane and the ring.

  According to the present invention, the three-dimensional truss is configured by the frame portion, the support column, and the cane in each support portion. That is, this solid truss forms a polygonal pyramid having a ring as a top vertex and a polygon formed by a connection point between the column and the cane and the frame, and the polygonal pyramid is turned upside down. Therefore, the solar panel can be stably supported, and it can sufficiently resist not only the load in the beam-to-beam direction but also the load in all directions including the beam direction. In addition, since the supporting portion is single, it can be installed even when the site is small and the unevenness is large.

  The frame portion 10 includes a plurality of beam members 11 extending in the column direction (X direction in FIG. 1), and a plurality of lines members extending in the beam-to-beam direction (Y direction in FIGS. 1 and 2) substantially perpendicular to the beam members 11. And an inter-beam member 12. The girder member 11 and the interbeam member 12 are arranged in a square shape.

  Each support portion 20 includes a cylindrical columnar column 21 exposed on the ground surface, and four wands 22 extending upward from the column 21 and connected to the frame unit 10.

  The support column 21 has a cylindrical shape and is driven into the ground. In addition, the upper end surface of the support column 21 is connected to the intersection of the cross member 11 and the interbeam member 12 of the frame portion 10. Assuming that the connecting portion between the support column 21 and the frame portion 10 is a connecting point 13A, the connecting point 13A is located at the center of the frame portion 10.

The four canes 22 have the same cross-sectional shape, and the upper ends of these canes 22 are connected to the intersections between the beam members 11 and the interbeam members 12 of the frame 10. Assuming that the connection point between the wand 22 and the frame portion 10 is a connection point 13B, the connection points 13B are located at the four corners of the frame portion 10.

Therefore, the solar panel can be stably supported, and it can sufficiently resist not only the load in the beam-to-beam direction but also the load in all directions including the beam direction.
Moreover, since the support part 20 was single, even if a site is narrow and unevenness is large, it can be installed.

  (2) Since the through-holes 231 are provided at predetermined intervals along the outer periphery of the ring joint 23, the number of the cane 22 can be freely increased or decreased by appropriately changing the connecting portion between the cane 22 and the ring joint 23. it can.

  (3) Since the column 21 and each cane 22 are connected to the connection point 13B, which is the intersection of the beam member 11 and the interbeam member 12, the rigidity of the gantry 1 can be improved.

(4) The cross-sectional shapes of the four canes 22 in each support portion 20 are substantially the same. Therefore, since the kind of member of the cane 22 can be reduced, the construction cost can be reduced and the quality control of the member used for the cane becomes easy.
Moreover, the shape of the joint connected with the frame part 10 can be unified about the four canes 22 of each support part, and manufacturing cost can further be reduced.

Assuming that the connection point between the cane 22 and the frame portion 10 is a connection point 13B, the connection point 13B is located at two corners away from the connection point 13A of the frame portion 10.

  Also in this embodiment, the beam member 11, the beam member 12, the support column 21, and these two canes 22 constitute a three-dimensional truss. In other words, this three-dimensional truss forms a triangular pyramid with the ring joint 23 as the head apex and a triangle composed of the connecting point 13A of the support column 21 and the connecting point 13B of the wand 22 as the bottom, and the triangular pyramid is turned upside down. It becomes the shape.
