CORE MATERIAL FOR SMALL-DIAMETER CAST-IN-PLACE PILE
To provide a core material for a small-diameter cast-in-place pile which reduces the number of components of the core material and can be also attached a rod material provided with rust-proofing treatment.SOLUTION: A core material for a small-diameter cast-in-place pile comprises: a rod material 20 having unevenness on an outer peripheral face; and a composite flange material 30 capable of being mounted to an outer peripheral face of the rod material 20 so as to clamp the rod material 20 from lateral sides. The composite flange material 30 comprises: a pair of divided cylinders 31, 31 capable of holding the rod material 20; a flange material 32 protruding on an outer peripheral face of each divided cylinder 31 along a peripheral direction; and a plurality of interval holding portions 3 radially protruding along an axial direction of the outer peripheral faces of the divided cylinders 31. The composite flange material 30 is integrally molded by a resin.SELECTED DRAWING: Figure 1
【課題】芯材の構成部品点数を削減し、防錆処理を施した棒材への取り付けも可能な小口径場所打ち杭用芯材を提供すること。【解決手段】外周面に凹凸を有する棒材２０と、棒材２０の外周面に棒材２０の側方から挟み込んで装着可能な複合鍔材３０とを具備し、複合鍔材３０は棒材２０に抱持可能な一対の分割筒３１，３１と、各分割筒３１の外周面で周方向に沿って突設した鍔材３２と、分割筒３１の外周面の軸方向に沿って放射状に突設した複数の間隔保持部３とを具備し、複合鍔材３０を樹脂で一体成形した。【選択図】図１
