Expanded head Structure拡頭構造e-tp

これまでのe-pile nextは､優れた掘削性能(貫入性)とα＝295という高支持力を特徴とした商品であるが故に､杭1本が負担できる鉛直荷重は大きいものの､同時に水平荷重も作用するため､曲げ耐力を考慮すると､杭の板厚および本数の増加が課題となっておりました｡
そこで､水平荷重を大きく受ける杭頭上部に拡頭構造を取り入れることで､断面性能の向上から､従来もつ高支持力を最大限活かすことを実現し､より経済性と安全性を高めることができました｡

  • 設計上必要な場合は、表中の厚さを超えて製作する場合があります。
  • SEAH590、HU590また、12.7㎜以上の厚さをご検討される場合は、弊社までお問い合わせください。
  • Z断面係数
  • F基準強度、STK400，SKK400では235N/mm²、STK490、STKN490B、SKK490では325N/mm²、SEAH590、HU590では440N/mm²
  • Rc低減率　Rc＝0.80＋2.5(t－c)/r
  • tくい体鋼管厚(mm)、c：腐食代(1mm)、r：くい体の半径(mm)
  • fc長期許容圧縮応力度　fc＝Rc・F/1.5
    ※SEAH590、HU590につても告示に従い低減させ使用する。
    短期許容圧縮応力度は、長期許容圧縮応力度の1.5倍
