従来、メガソーラー等のソーラーパネル用架台の設置には、造成工事やコンクリートを用いた基礎工事を行う大規模なプロジェクトが行われており、重機や多くの人手を必要とする。一方で、近年、売電価格の低下とともに、狭い土地や農地等の複雑な地質及び形状を有する土地にソーラーパネルを設置する小規模なプロジェクトが増えており、より簡易に設置可能な方法が求められてきている。簡易に各種構造物の設置を可能にする方法として、特許文献1~3には、各種構造物の施工にかかる費用を抑えつつ、短い工期で構造物を設置できる杭基礎等が提案されている。 Conventionally, the installation of a solar panel mount for a mega-solar plant or the like involves a large-scale project involving land preparation work and foundation work using concrete, which requires heavy machinery and a lot of manpower. On the other hand, in recent years, as the selling price of electricity has declined, there has been an increase in the number of small-scale projects that install solar panels on land with complex geological features and shapes, such as small plots of land or agricultural land. It is getting worse. As a method for easily installing various structures, Patent Documents 1 to 3 propose pile foundations and the like that can install structures in a short construction period while suppressing the cost of constructing various structures. .

FIG. 2 shows a schematic top view of an example of the base member 100. As shown in FIG. FIG. 3 shows a schematic bottom view of an example of the base member 100. As shown in FIG. FIG. 4 shows a schematic side view of an example of the base member 100. As shown in FIG. FIG. 5 shows a schematic front view of an example of the base member 100. As shown in FIG.

本ベース部材100は、支柱を支持するための固定部が、支柱を支持するためのL字形状の側部11と側部11に一体化された底部12とで構成される。L字形状の側部11のそれぞれは、支柱をボルトで固定するための貫通孔13を本体部14の軸心に平行方向に少なくとも2つ備える。貫通孔13は、側部の面に垂直方向に貫通する孔である。図1、4及び5に示す例においては、L字形状の側部11のそれぞれは、3つの貫通孔13を備える。L字形状の側部11のそれぞれが備える貫通孔13の数は、2つ以上、好ましくは3つ以上、より好ましくは4つ以上、さらに好ましくは5つ以上である。貫通孔13の数の上限は特に限定されないが、例えば7つまたは6つであることができる。 In the base member 100 , a fixing portion for supporting the support column is composed of an L-shaped side portion 11 for supporting the support column and a bottom portion 12 integrated with the side portion 11 . Each of the L-shaped side portions 11 has at least two through-holes 13 for fixing the support with bolts in a direction parallel to the axis of the body portion 14 . The through hole 13 is a hole penetrating through the surface of the side portion in a vertical direction. In the examples shown in FIGS. 1, 4 and 5, each of the L-shaped sides 11 is provided with three through-holes 13 . The number of through-holes 13 provided in each L-shaped side portion 11 is two or more, preferably three or more, more preferably four or more, and still more preferably five or more. Although the upper limit of the number of through-holes 13 is not particularly limited, it can be seven or six, for example.

L字形状の側部11のそれぞれが備える貫通孔13の数は、同じでもよく異なってもよい。L字形状の2つの側部11が備える複数の貫通孔13の、本体部14の軸心14Cに平行方向の位置(以下、貫通孔の位置ともいう)は、同じでもよく異なってもよい。 The number of through-holes 13 provided in each of the L-shaped side portions 11 may be the same or different. The positions of the plurality of through holes 13 provided in the two L-shaped side portions 11 in the direction parallel to the axis 14C of the body portion 14 (hereinafter also referred to as the positions of the through holes) may be the same or different.

貫通孔の位置が同じ場合、それぞれの側部11の貫通孔13から挿入するボルト同士が干渉しないように、それぞれの側部11の異なる位置の貫通孔からボルトを挿入する。例えば、図1に例示するように、それぞれの側部11がそれぞれ3つの貫通孔を有する場合に、それぞれの側部11を第1の側部及び第2の側部と呼び、且つ底部12に近い貫通孔から第1の貫通孔、第2の貫通孔、及び第3の貫通孔と呼ぶとすると、第1の側部の第1の貫通孔及び第2の貫通孔にボルトを挿入し、第2の側部の第3の貫通孔にボルトを挿入して支柱を固定することにより、2つ側部11から挿入するボルト同士が干渉せずに支柱をL字形状の2つの側部11に固定することができる。 When the positions of the through-holes are the same, the bolts are inserted through the through-holes of different positions of the side portions 11 so that the bolts inserted through the through-holes 13 of the respective side portions 11 do not interfere with each other. For example, as illustrated in FIG. 1, if each side 11 has three through-holes, each side 11 is called a first side and a second side, and the bottom 12 has inserting a bolt into the first through hole and the second through hole on the first side, assuming that the first through hole, the second through hole, and the third through hole are referred to from the nearest through hole; By inserting bolts into the third through-holes of the second side to fix the support, the bolts inserted from the two sides 11 do not interfere with each other and the support is attached to the two L-shaped sides 11 . can be fixed to

貫通孔の位置が異なる場合、それぞれの側部11から挿入するボルト同士が干渉しないように貫通孔の位置がずれていることが好ましい。この場合、どの貫通孔にボルトを挿入しても、2つ側部11から挿入するボルト同士が干渉せずに支柱をL字形状の2つの側部11に固定することができる。 When the positions of the through holes are different, it is preferable that the positions of the through holes are shifted so that the bolts inserted from the respective side portions 11 do not interfere with each other. In this case, the bolts inserted from the two side portions 11 can be fixed to the two L-shaped side portions 11 without interfering with each other regardless of which through hole the bolt is inserted into.

側部11と底部12とは、一体成形されたものでも溶接されたものでもよい。それぞれの側部の2つ以上の貫通孔13の重心は、好ましくは、それぞれの側部の重心と実質的に一致する。貫通孔13の重心が側部の重心と実質的に一致することにより、支柱をより強固に固定することができる。 Sides 11 and bottom 12 may be integrally molded or welded together. The center of gravity of the two or more through holes 13 on each side preferably substantially coincides with the center of gravity of the respective side. By substantially matching the center of gravity of the through hole 13 with the center of gravity of the side portion, the support can be fixed more firmly.

固定部の底部12で支柱の鉛直方向の質量を支え、L字形状の側部11で支柱を固定することができるので、固定部の形状を変更しなくても、2つの側部の貫通孔13を介して固定可能な範囲で、円柱形状、角形形状等の任意の形状、及び任意の太さの支柱を固定することができる。このように、本ベース部材100によれば、支柱の形状及び太さの制限が少なく汎用性に優れる。 The bottom part 12 of the fixing part supports the vertical mass of the column, and the L-shaped side part 11 can fix the column, so that the two side through-holes can be used without changing the shape of the fixing part. It is possible to fix a post of any shape, such as a cylindrical shape or a square shape, and any thickness within the range that can be fixed via 13 . Thus, according to the base member 100, there are few restrictions on the shape and thickness of the strut, and it is excellent in versatility.

The body portion 14 has a tubular shape so that it can be easily embedded in the ground. An axis 14</b>C of body portion 14 is substantially perpendicular to the surface of bottom portion 12 . The shape of the body when viewed in a direction perpendicular to the surface of the bottom 12 (parallel to the axis of the body 14) is rectangular, circular, polygonal, or a combination thereof, preferably rectangular. Since the main body has a rectangular cross-sectional shape, it is easy to firmly fix the pile guide described below to the side surface of the main body. A side surface of the body portion 14 extends parallel to the axis 14</b>C of the body portion 14 . The body portion 14 preferably has a thickness of 2-8 mm, more preferably 3-7 mm, and even more preferably 4-6 mm.
