Description

本考案は、地中に埋設されたスクリュ基礎杭において、スクリュ基礎杭の軸心直交方向(水平方向)の耐力を向上できるスクリュ基礎杭ユニット、及び杭頭ロックに関する。   The present invention relates to a screw foundation pile unit and a pile head lock that can improve the proof stress in the direction perpendicular to the axis of the screw foundation pile (horizontal direction) in a screw foundation pile buried in the ground.

スクリュ基礎杭として、特許文献1は、捩り平鋼及びパイプでなるスパイラル杭を開示する。スパイラル杭は、パイプの軸心方向において、捩り平鋼をパイプの一軸端に溶接等で接合して、軸心方向に、パイプ及び捩り平鋼を連続して配置する。
特許文献1では、捩り平鋼を地中に捩じ込み、捩り平鋼及びパイプの一部を地中に埋設し、パイプの一部以外を地面から突出する(図2参照)。
As a screw foundation pile, patent document 1 discloses the spiral pile which consists of a twisted flat bar and a pipe. In the spiral pile, a twisted flat bar is joined to one end of the pipe by welding or the like in the axial direction of the pipe, and the pipe and the twisted flat bar are continuously arranged in the axial direction.
In Patent Document 1, a twisted flat bar is screwed into the ground, a part of the twisted flat bar and the pipe are embedded in the ground, and a part other than the pipe protrudes from the ground (see FIG. 2).

特許文献1では、捩り平鋼を地中に捩じ込むことで、スパイラル杭の軸心方向の耐力(抜け力)を確保できるものの、軸心直交方向(水平方向)の耐力は脆弱であり、地面から突出するパイプに対して軸心直交方向(水平方向)に力が作用すると、スパイラル杭が軸心直交方向(水平方向)に傾斜して倒れ込む虞がある。   In Patent Document 1, by twisting a twisted flat steel into the ground, the proof stress in the axial direction (disengagement force) of the spiral pile can be secured, but the proof strength in the direction orthogonal to the axial center (horizontal direction) is fragile, If a force acts in a direction perpendicular to the axis (horizontal direction) on the pipe protruding from the ground, the spiral pile may incline in a direction perpendicular to the axis (horizontal direction) and fall down.
