  Reference numeral 10 denotes a frame-shaped main body, which is formed in a rectangular frame shape by a steel structure. The steel structure of the present embodiment is formed in a rectangular frame shape by welding H-shaped steel, and has a high rigidity strength. In addition, as a steel frame material, I-shaped steel having higher rigidity and strength can be used, and it can be appropriately reinforced in accordance with specifications.

  The frame-shaped main body 10 according to the present embodiment includes a pair of long frame members 11 and 11 arranged in the longitudinal direction and a plurality of rectangular frames by being fixed at right angles between the pair of long frame members 11 and 11. It is comprised by the 3 or more short frame member 12 distribute | arranged so that a shape may be formed. The size of the frame-shaped main body portion 10 in this embodiment is designed to be, for example, about 9 m in length in the longitudinal direction and 2.3 m in width, and can be transported by truck.

  Reference numeral 30 denotes an earth and sand placing plate portion, and the earth and sand are placed as a weight by closing the inside 20 of the frame-like main body portion 10 except for the opening portion 21 through which rainwater can pass through the inside of the frame 20. The frame-shaped main body 10 is fixed to the lower surface of the frame-shaped main body 10 in parallel with the frame surface. Thus, depending on the weight of the steel material constituting the steel frame foundation for installing the photovoltaic power generation panel (the weight of the steel structure itself of the present invention) and the weight of the earth and sand thrown into and placed in the frame 20, The steel frame foundation for installing the photovoltaic panel can be appropriately fixed to the ground, and rainwater can penetrate into the ground from the opening 21. Moreover, even if an earthquake occurs, it is not fixed to the ground, so it has a flexible configuration that does not directly receive the shaking. That is, it has a configuration that can sufficiently and flexibly withstand disasters such as feng shui and earthquakes.

  Two rectangular earth and sand placing plate portions 30 are fixed in the frame 20 so as to close the inner corners of the four corners of the frame 20. That is, a portion of the frame 20 that is not covered by the two earth and sand placing plate portions 30 is a rectangular opening 21. As described above, by arranging the rectangular earth and sand placing plate portion 30 so as to block the inner corner portions of the four corners, the rigidity strength of the frame-shaped main body portion 10 can be increased, and the deformation of the dimension occurs due to the deformation. Can be prevented.

  The earth and sand placing plate portion 30 of this embodiment is fixed along the length direction of the short frame member 12 and is an end on the opening 21 side provided in the frame 20 of the earth and sand placing plate portion 30. An in-frame bending claw portion 41 that prevents the frame-like main body portion 10 from slipping in the longitudinal direction is provided by projecting into a shape bent downward at the side. Thus, since the end side of the earth and sand placing plate portion 30 is bent, the rigidity strength can be increased at low cost. Also by this, the whole rigidity strength concerning the frame-shaped main-body part 10 can be enlarged, and it can prevent that the deformation | transformation of a dimension arises by a deformation | transformation. In addition, the in-frame bending claw part 41 is not limited to this form, For example, it can comprise also by fixing an angle to the lower surface of the earth and sand mounting board part 30 by welding.

  42 is a frame part lower surface nail | claw part, provided in the lower surface of a pair of long frame members 11 and 11 so that it may protrude below, and can prevent the slip to the direction orthogonal to a longitudinal direction. In this embodiment, an angle (an angle steel) is intermittently fixed to the lower surface of the lower horizontal plate portion of the H-shaped steel constituting each long frame member 11 by welding. In the present embodiment, the angle is fixed at three locations in the longitudinal direction to constitute the frame lower surface claw portion. Note that the length of the angle and the installation location are not limited to those of the present embodiment, and may be appropriately and selectively set according to the conditions of the installation location. For example, the angle can be fixed to the lower surface of the short frame member 12 by welding or the like to prevent the sliding in the longitudinal direction.

  Further, according to the embodiment shown in FIGS. 7 to 12, the single pipe 61 that constitutes the mounting base 60 for fixing the solar power generation panel 70 is provided with a single pipe at a distance from the outside of the frame-shaped main body 10. A plurality of fixing pipe-like portions 50 are fixedly arranged so that they can be fixed by the clamp 62. In this embodiment, the fixing pipe-like portion 50 is fixed by welding between the upper and lower horizontal plate portions of the long frame member 11 formed of the H-shaped steel of the frame-like main body portion 10. More specifically, the fixing pipe-like portion 50 according to the present embodiment is formed by cutting a single pipe and is an H-shape that constitutes the long frame member 11 so as to stand in a vertical direction when installed. Upper and lower end portions are welded and fixed to the upper and lower horizontal plate portions of the steel. Further, a gap 51 is formed between the standing plate portion of the H-shaped steel and the pipe peripheral surface of the fixing pipe-like portion 50, and the single pipe clamp 62 is fitted using this gap 51 to allow sunlight. The single pipe 61 constituting the mounting base 60 for fixing the power generation panel 70 can be fixed to the fixing pipe-like portion 50. Thereby, the mount frame 60 for fixing the photovoltaic power generation panel 70 can be fixed to the steel frame foundation for installing the photovoltaic power generation panel according to the present invention (see FIG. 12).

Next, merits of the steel frame foundation for solar power generation panel installation according to the present invention (hereinafter also referred to as “steel frame foundation”) will be listed and described.
First, the steel foundation according to the present invention can be easily assembled with a stand such as a single pipe placed on the ground such as soil, and the construction period can be shortened. That is, the steel frame foundation itself requires fewer construction days on site for processing and production at the factory. Since the steel frame (frame-shaped main body portion 10) and the iron plate (the earth and sand placement plate portion 30) have a dope-dipping plating specification, the occurrence of rust and the like is small and the durability is long. For example, durability of 20 years or more can be obtained. This steel foundation does not require complicated processing and can reduce manufacturing costs. The maximum length and width of the steel frame foundation are within the range that can be transported by a large truck and can be manufactured at the factory. For wind pressure load, the amount of earth and sand put in the frame 20 can be dealt with by changing the size of the steel H-shaped steel. Since the opening between the iron plate and the iron plate is open, drainage is good. Plants can be grown on the earth and sand, and the landscape can be improved.

  When disposing of this steel frame foundation, it is composed of only iron materials that can be sold for reuse and local earth and sand, so there is no industrial waste, and there is almost no disposal cost. Also good. Since it is not necessary to dig up the soil deeply, it can be installed in places where there are buried cultural properties or landfills with industrial waste. Since the material is iron and is in great contact with the ground, it can also serve as an electrical ground. The solar power panel can be installed simply by placing the steel foundation horizontally, and the horizontal and vertical dimensions for fixing a stand such as a single pipe on the upper side of the steel foundation will not be out of order, and it will be finished easily and cleanly. It can be installed. Since the steel foundation is integrated, movement and position correction with heavy machinery can be performed easily and quickly. Moreover, since the height of loading of conveyance is fundamentally determined by the magnitude | size of H-section steel, it can be piled up and conveyed in large quantities at once.

  The pedestal of the photovoltaic power generation panel only needs to be attached to the attachment pipe (fixing pipe-like portion 50) fixed to the steel frame foundation with a single pipe clamp, and can be simplified in a short time and at a low cost. The installation work can be done easily in a short time, at a low cost, by simply placing the steel foundation horizontally. Around this steel frame foundation, makeup can be easily applied and it can be configured like a flower bed. Since this steel frame foundation can be manufactured as one unit, no step or angle adjustment is required, the appearance is good, and it can be installed easily and quickly. The steel foundations can be easily connected using a pipe. Since the mount can be made cheaply and quickly, the construction cost of the entire photovoltaic power generation system can be reduced. In addition, relocation after construction can be easily performed. With respect to wind pressure load, the amount of earth and sand is secured, and the projection claws (for example, the in-frame bending claw portion 41 and the frame lower surface claw portion 42) provided at the lower part of the steel frame can withstand more appropriately. be able to.

  The size of the H-shaped steel that constitutes the frame-shaped main body portion 10 of the steel frame may be determined by calculating the amount of earth and sand entering by wind pressure load calculation such as the number of solar power generation panels and the installation angle. Moreover, what is necessary is just to set an area suitably also about an iron plate (the earth-and-sand mounting board | plate part 30) with the quantity in which earth and sand enter. The outer diameter of the mounting pipe (fixing pipe-like portion 50) attached to the steel foundation by welding matches the thickness of the single pipe 61 that constitutes the base, and the base 60 can be fixed by the single pipe clamp 62. (See FIG. 12).

On slopes, it is only necessary to excavate the area of the steel frame horizontally like terraced fields, and the scenery is good and construction is easy. In addition, if the upper half of the sloped land is embanked in the lower half, there is no need to carry out sediment, the shape of the land can be changed minimally, and the environment can be considered. There is basically no skidding due to the weight of the earth and sand, but as a precautionary measure, the in-frame bent claw part 41 and the frame lower part claw part 42 (the height and thickness are determined by the specifications of the site) are stuck in the ground. . In addition, since the in-frame bending claw portion 41 of the earth and sand placing plate portion 30 (iron plate) is bent, the strength of the iron plate when the earth and sand are placed can be increased. Moreover, although soil is put on the iron plate, since the iron plate is put into the H-section steel and welded, it does not come off by weight. Since one unit is put together, no assembly is required, so there is no error during movement, it is easy to handle lightly, and the base is easy to assemble. There is no soil in the steel foundation during transportation, and the soil is put in after installation, so it is easy to move lightly by the weight of the steel frame.
In addition, by setting up H-shaped steel etc. on this steel frame foundation, it can be used as a wire pull-in column, and it can also be used as a foundation for a self-standing board or cubicle.

  As described above, the present invention has been described in various ways with preferred embodiments. However, the present invention is not limited to these embodiments, and many modifications can be made without departing from the spirit of the invention. That is.
