［２］施工方法
次に芯出し具１０を用いた芯出し〜杭打設の方法について説明する。 [2] Construction Method Next, a method of centering to pile driving using the centering tool 10 will be described.

（１）芯出し工程
整地した地盤上にユニットの配置位置に合わせた基準杭の打設位置を決め、その位置と芯出し具１０及び打設孔１１が一致するように、芯出し具１０ａを配置する。
芯出し具１０は可撓性を有する帯状の部材であるため、軽量で丸めたり折り曲げたりすることができ、現場への搬入や地盤上への配置が容易である。
芯出し具１０が複数の打設孔１１を有する場合、基準杭以外の支持杭２０の打設位置も決まる。 (1) Centering process Determine the placement position of the reference pile according to the arrangement position of the unit on the leveled ground, and adjust the centering tool 10a so that the position coincides with the centering tool 10 and the placement hole 11. Deploy.
Since the centering tool 10 is a flexible belt-like member, it can be lightly rounded and bent, and can be easily brought into the field or placed on the ground.
When the centering tool 10 has a plurality of placement holes 11, the placement positions of the support piles 20 other than the reference pile are also determined.

住宅を構成するユニットの形状に合わせて複数種から予め選定した、芯出し具１０ａに隣接する芯出し具１０ｂ、１０ｃを配置していく。（図２）
芯出し具１０ａに係合させて１０ｂ、１０ｃと配置していくだけで、基準杭以外の支持杭２０の打設位置も決まる。
いずれかの基準点から測量することなく、芯出し具１０を組み合わせるだけで支持杭２０の打設位置が決まるため、芯出しが容易に行うことができる。 Centering tools 10b and 10c adjacent to the centering tool 10a, which are selected in advance from a plurality of types according to the shape of the unit constituting the house, are arranged. (Figure 2)
The placement position of the support pile 20 other than the reference pile is determined only by engaging with the centering tool 10a and arranging them as 10b and 10c.
Since the placement position of the support pile 20 is determined only by combining the centering tool 10 without measuring from any reference point, the centering can be easily performed.

（２）杭設置〜打設工程
配置した芯出し具１０の打設孔１１に合わせて支持杭２０を設置し、打設していく。（図３）
打設孔１１は支持杭２０よりも径が大きいため、芯出し具１０を地盤上に配置したままの状態で支持杭２０を打設することができる。
また、支持杭２０は打設孔１１を基準として打設することができるため、支持杭２０の位置ずれや、打設途中での芯ずれを防止することができる。 (2) Pile installation to placing process The support pile 20 is installed and placed in accordance with the placement hole 11 of the centering tool 10 arranged. (Figure 3)
Since the diameter of the placement hole 11 is larger than that of the support pile 20, the support pile 20 can be placed in a state where the centering tool 10 is disposed on the ground.
Moreover, since the support pile 20 can be driven on the basis of the driving hole 11, the position shift of the support pile 20 and the misalignment during the driving can be prevented.

芯出し具１０は支持杭２０と係合したりするものではないため、支持杭２０打設後は回収して、同一構築物の別の支持杭打設箇所の芯出しや、他の構築物の芯出し等、繰り返し利用できる。
芯出し具１０は軽量で丸めたり折り曲げたりすることができるため、現場での回収や現場からの搬出が容易である。 Since the centering tool 10 does not engage with the support pile 20, the centering tool 10 is collected after the support pile 20 has been placed, and can be centered at another support pile placement location of the same structure or the core of another structure. Can be used repeatedly such as taking out.
Since the centering tool 10 is lightweight and can be rounded or bent, it can be easily collected at the site or taken out from the site.

［その他実施例］
