当該支持杭１の上端部の側部に鉄骨材等からなるシアコ
ツター４，４とアンカー鉄筋５．５が略水平に突設され
ている。On the side of the upper end of the support pile 1, shear rods 4, 4 made of steel frames or the like and anchor reinforcing bars 5.5 are provided to project approximately horizontally.
基礎固定体２はプレキャストコンクリ−トヨり矩形断面
若しくは円形断面の短い柱状に形成され、その下端部に
は支持杭１の上端部をシアコツター４．４と共に挿入で
きるような凹部６か形成されている。The foundation fixing body 2 is formed of precast concrete in the shape of a short column with a rectangular or circular cross section, and a recess 6 is formed at the lower end thereof into which the upper end of the support pile 1 can be inserted together with the cylinder blocker 4.4. .
また、基礎固定体２の略中央部には上端より前記凹部６
に通じるグラウト注入孔７が略鉛直に形成されている。Further, the recess 6 is provided at the substantially central portion of the foundation fixed body 2 from the upper end.
A grout injection hole 7 communicating with is formed substantially vertically.
なお、基礎固定体２の径は構築しようとする建物の規模
等により適当に決められている。Note that the diameter of the foundation fixing body 2 is appropriately determined depending on the scale of the building to be constructed.
このように形成された基礎固定体２は各支持杭ｌの上端
部に支持杭１の上端部を凹部６に挿入した状態に設置さ
れている。The foundation fixed body 2 thus formed is installed at the upper end of each support pile l with the upper end of the support pile 1 inserted into the recess 6.
また、グラウト注入孔７より凹部６内及び支持杭１上端
の中空部にグラウト材８が充填され、かかる構成により
、基礎固定体２は支持杭１の上端部に一体的に固定され
ている。In addition, grout material 8 is filled into the recess 6 and the hollow part at the upper end of the support pile 1 through the grout injection hole 7, and with this configuration, the foundation fixing body 2 is integrally fixed to the upper end of the support pile 1.
図中、番号９は支持杭１上端部の中空部に充填されたグ
ラウト材８がこれより下側に流れ込まないように取り付
けられた底蓋である。In the figure, number 9 is a bottom cover attached to prevent the grout 8 filled in the hollow part of the upper end of the support pile 1 from flowing below.
また、番号１０は基礎固定体２の座りを良くする為に根
切り底に設けられた地業であり、割栗石１１の上にドラ
イモルタル（捨てコンクリート）１２を打設することに
より行われている。In addition, number 10 is a groundwork provided at the bottom of the root cut to improve the seating of the foundation fixing body 2, and this is done by pouring dry mortar (saved concrete) 12 on top of the split stone 11. There is.
基礎３には■形鋼等が使用され、当該基礎３は基礎固定
体２の上に複数本の埋込みポル） １３゜１３或いは雄
ねじアンカー、雌ねじアンカー、タッピングアンカー、
その他の固定金具によって固定されている。■Shaped steel etc. are used for the foundation 3, and the foundation 3 has multiple embedded poles on the foundation fixing body 2) 13° 13 or male threaded anchor, female threaded anchor, tapping anchor,
Fixed by other fixing hardware.
基礎３のコーナ部等、基礎３の仕口部には、接合ブラケ
