Description

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

  2. Description of the Related Art Conventionally, a solar panel that generates electricity using light energy of sunlight is known. 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, a gantry shown in FIGS. 5 to 7 has been proposed.

  The gantry 100 supports the solar panel 2, and includes a planar frame portion 10 on which the solar panel 2 is placed, and at least four supports that extend substantially vertically from the ground surface and support the frame portion 10. Unit 40.

The frame portion 10 includes a plurality of column members 11 extending in the column direction (X direction in FIGS. 5 to 7), and a plurality extending in the beam-to-beam direction (Y direction in FIGS. 5 to 7) substantially perpendicular to the column members 11. The inter-beam member 12 is provided.
Further, when the connection portion between the support portion 40 and the frame portion 10 is a connection point 13, the connection point 13 is an intersection of the beam member 11 and the interbeam member 12.

  However, when a flat solar panel that is heavy and impervious to wind is placed on such a gantry 100, the solar panel is stably supported against loads caused by earthquakes and winds. It becomes difficult. In order to support it stably, it is conceivable to increase the strength of the pedestal by increasing the cross section of each member or by reinforcing with a reinforcing material or a connecting material, or to increase the fixing degree of the foundation. For example, the mount shown in patent document 1 is proposed.

In other words, the gantry includes a rectangular beam on which the solar panel is mounted, and a plurality of support portions that support the beam.
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.

  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.

  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.

JP 2011-220096 A

However, in the above frame, different types of steel materials are used for the support and the arm, and there is a problem that the material cost increases.
Also, because the struts and a pair of arms are arranged in a straight line on the vertical beam, the truss structure can resist loads in the beam direction due to wind and earthquakes, but it cannot sufficiently resist loads in the beam direction. was there.

  However, in order to increase the total stability, it is necessary not only to increase the strength of the gantry but also to take measures to increase the fixing degree of the foundation. In particular, for the pulling force by wind, it is effective to make the foundation larger or use the pile foundation, but it is costly to raise the fixing degree of all the column foundations.

  In addition to being able to sufficiently resist loads in all directions including the direction of the beam while reducing material costs, the present invention stabilizes the solar panel especially against wind pulling force. The object is to provide a support that can be supported.

  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 part (for example, a frame part 10 described later) and at least four support parts (for example, a support part 20 described later) that extend upward from the ground surface and support the frame part, A plurality of beam members extending in the column direction (for example, a beam 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 support portion includes a foundation (for example, a later-described foundation 21) and at least three wands (for example, a later-described wand 22) that extend upward from the foundation and are coupled to the frame portion. Features.

According to this invention, in each support part, a solid truss is comprised with a frame part and a cane. That is, this solid truss forms a polygonal pyramid having the base as the head vertex and the wand extending from the head vertex, 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. Moreover, since it is uniformly transmitted to the foundation through the diagonal member against the pulling force caused by the wind, the pulling force can be efficiently resisted with a thin wand and a small foundation.
Furthermore, since the support | pillar extended substantially perpendicularly becomes unnecessary like the past, material cost can be reduced by forming each wand with a single steel material.

  The gantry according to claim 2 is characterized in that each of the wands is connected to an intersection of the beam member and the beam member.

  According to this invention, since each wand is connected to the intersection of the beam member and the beam member, the rigidity of the gantry can be improved.

  The gantry according to claim 3 is characterized in that the cross-sectional shapes of the cane of the support portion are substantially the same, and the lengths thereof are substantially equal.

According to this invention, the cross-sectional shape of the cane in each support part was made substantially the same, and the length was made substantially equal. Therefore, since the kind of member of a cane can be reduced, construction cost can be reduced and quality control of the member used for a cane becomes easy.
Moreover, about the four canes of each support part, the shape of the joint connected with a frame part can be unified, and manufacturing cost can further be reduced.

  According to the present invention, the three-dimensional truss is configured by the frame portion and the cane in each support portion. That is, this solid truss forms a polygonal pyramid having the base as the head vertex and the wand extending from the head vertex, 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. Moreover, since it is uniformly transmitted to the foundation through the diagonal member against the pulling force caused by the wind, the pulling force can be efficiently resisted with a thin wand and a small foundation. Furthermore, since the support | pillar extended substantially perpendicularly becomes unnecessary like the past, material cost can be reduced by forming each wand with a single steel material.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
FIG. 1 is a perspective view of a gantry 1 according to an embodiment of the present invention. FIG. 2 is a side view of the gantry 1, and FIG. 3 is a plan view of the gantry 1. 1 to 3 show a part of the gantry 1, and the gantry 1 can be continuously installed in the direction of the row (X direction in FIGS. 1 to 3).

  The gantry 1 supports the solar panel 2, and includes a planar frame portion 10 on which the solar panel 2 is placed and at least four support portions that extend upward from the ground surface and support the frame portion 10. 20.

The frame portion 10 includes a plurality of column members 11 extending in the column direction (X direction in FIGS. 1 to 3), and a plurality extending in the beam-to-beam direction (Y direction in FIGS. 1 to 3) substantially perpendicular to the column members 11. The inter-beam member 12 is provided.
The cross member 11 is, for example, a 100 × 40 × 2.3 channel steel material arranged back to back. The inter-beam member 12 is, for example, a channel steel material of 100 × 50 × 3.2.

Each support portion 20 includes a base 21 exposed on the ground surface, and four wands 22 extending upward from the base 21 and connected to four connection points 13 of the frame portion 10.
Each of the connection points 13 is an intersection of the beam member 11 and the inter-beam member 12, and these four connection points 13 are located at the vertices of a rectangle formed by the two beam members 11 and the two beam members 12. doing.

The four wands 22 have the same cross-sectional shape, and are, for example, steel pipes having a diameter of 42.7 × 2.3.
The lengths of the four wands 22 are substantially equal, and the beam member 11, the inter-beam member 12, and the four wands 22 form a three-dimensional truss. That is, this solid truss has a shape in which the base 21 is a head apex, and the bottom surface having the four sides extending from the head apex is a rectangular pyramid, and the quadrangular pyramid is turned upside down. .

Therefore, the position in the inter-beam direction (Y direction) of the foundation 21 is on the vertical bisector A of the line segment connecting the two connection points 13 on one inter-beam member 12 as shown in FIG. .
Further, the position of the foundation 21 in the column direction (X direction) is on the vertical bisector B of the line segment connecting the two connection points 13 on one column member 11 as shown in FIG. .

The above gantry 1 is constructed in the following procedure, for example.
First, as shown in FIG. 4, a precast concrete member 30 in which the foundation 21 and the cane 22 are integrated is prepared. The precast concrete member 30 includes a groove member 31 having a substantially U-shaped cross section, a foundation 21 that is a concrete lump placed inside the groove member 31, and a wand 22 driven into the foundation 21. Prepare. By placing this precast concrete member 30 on the ground surface, the foundation 21 and the cane 22 are placed on the ground surface.
Next, the frame 10 is placed on the cane 22 and joined to the cane 22, and then the solar panel 2 is installed on the frame 10.

According to this embodiment, there are the following effects.
(1) In each support part 20, the frame part 10 and the four canes 22 constitute a solid truss. 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 it is uniformly transmitted to the foundation 21 via the wand 22 with respect to the pulling force due to the wind, the pulling force can be efficiently resisted with a thin wand and a small foundation.
Furthermore, since the support | pillar extended substantially perpendicularly becomes unnecessary like the past, material cost can be reduced by forming each cane 22 with a single steel material.

  (2) Since each of the canes 22 is connected to the connection point 13 that is the intersection of the beam member 11 and the interbeam member 12, the rigidity of the gantry 1 can be improved.

(3) The cross-sectional shapes of the four wands 22 in each support portion 20 are substantially the same, and the lengths thereof are substantially equal. 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.

It should be noted that the present invention is not limited to the above-described embodiment, and modifications, improvements, etc. within a scope that can achieve the object of the present invention are included in the present invention.
For example, in the present embodiment, the number of wands 22 constituting the support portion 20 is four, but is not limited to this, and may be three, or five or more.
In the present embodiment, the beam members 11, the beam members 12, and the cane 22 are made of steel. However, the present invention is not limited thereto, and may be made of wood or reinforced concrete, and used for the beam members, the beam members, and the cane. The material is not particularly limited.
In the present embodiment, the cross-sectional shape of the cane 22 is an annular shape.
Moreover, in this embodiment, although the foundation 21 was made into the direct foundation by the precast concrete member 30, not only this but a foundation may be used as pile foundations, such as a ready-made pile and a drill-shaped pile, and the shape of a foundation is not specifically limited. .
