【０００１】[0001]

[Industrial applications]

土木・建築工事現場で地面に打設する杭に関する。 Regarding piles to be laid on the ground at civil engineering and construction sites.

【０００２】[0002]

[Prior art]

土木工事・建築工事現場等で地面に打設する杭は、従来両端面開口の鋼管をそのまま地面に打ち込んで杭としていた。 Conventionally, the piles that are driven into the ground at civil engineering / construction construction sites have been constructed by driving steel pipes with openings on both end faces into the ground as they are.

【０００３】[0003]

[Problems to be solved by the device]

従来の、両端開口の鋼管を杭に使用する場合、頂部からハンマー等で槌打するが地中への食い込みが悪く打設が困難で、一層槌打が激しくなり、頂部が潰れたり、変形したり、裂けたりする。更に杭の打設後頂部の開口端から水や塵芥が入る。又下端部切り口が土砂により潰れたり変形し、土砂が侵入した。本考案は、このような欠点を解決するよう工夫されたものである。 When using conventional steel pipes with openings at both ends, hammering from the top with a hammer etc. is difficult to set into the ground because the bite into the ground is poor and the hammering becomes more violent and the top is crushed or deformed. Do it or tear it. Furthermore, water and dust will enter from the open end of the top after driving the pile. In addition, the cut end of the lower end was crushed or deformed by the earth and sand, and the earth and sand entered. The present invention has been devised to solve such a drawback.

【０００４】[0004]

[Means for Solving the Problems]

鋼管の下端開口部に円錐形の錐脚を、該鋼管内部に内接するような板ばねで挿入し、槌打した場合、杭が地面に食い込み易くし、下端部切り口が土砂により潰れたり、変形して土砂が侵入しないように工夫した。又鋼管の頂部には、円筒形のキャップを、該鋼管外周に接入するような板ばねで蓋閉し、ハンマー等で槌打しても鋼管が潰れたり、変形したり、裂けたりしないようにする。 If a conical pyramidal leg is inserted into the lower end opening of the steel pipe with a leaf spring that is inscribed inside the steel pipe and hammered, the pile will easily bite into the ground and the lower end cut may be crushed by earth and sand. , It was devised so that it would not be deformed and soil would enter. At the top of the steel pipe, a cylindrical cap is closed with a leaf spring that comes into contact with the outer circumference of the steel pipe so that the steel pipe will not be crushed, deformed, or torn even if it is hammered with a hammer or the like. To

【０００５】なお、該鋼管杭は、蓋閉してあるので雨水や塵芥が入ることがない。Since the steel pipe pile is closed, rainwater and dust do not enter.

【Example】

図１（ｂ）本考案の組み立て断面図を示す。鋼管１の下端開口部に円錐形の錐脚２を、前記錐脚２の上部円周に固着した板ばね２’で挿入し、前記鋼管１の上部は、該鋼管１に外接する板ばね３’を持つキャップ３で蓋閉する。円筒形のキャップの上面は外に向かって凸形を形成し複数の平坦部からなり、槌打に対して強度を持たせてある。本考案の杭を使用する場合は、錐脚２を下にして地上に立て、頂部のキャップ３の上からハンマー等で槌打して杭を打設する。図１（ａ）は（ｂ）のＡ−Ａ断面図で図１（ｃ）は（ｂ）のＢ−Ｂ断面図である。 FIG. 1 (b) shows an assembled sectional view of the present invention. A cone-shaped conical leg 2 is inserted into the lower end opening of the steel pipe 1 with a leaf spring 2'fixed to the upper circumference of the conical leg 2, and the upper portion of the steel pipe 1 is circumscribed to the steel pipe 1. Close the lid with the cap 3 having 3 '. The upper surface of the cylindrical cap is convex toward the outside and is composed of a plurality of flat parts, which is strong against hammering. When the pile of the present invention is used, the pile leg 2 is placed on the ground, and the pile 3 is hammered from above the top cap 3 with a hammer or the like to drive the pile. 1A is a sectional view taken along the line AA of FIG. 1B, and FIG. 1C is a sectional view taken along the line BB of FIG. 1B.

[Effect of device]

本考案の効果は次の通りである。 The effects of the present invention are as follows.

【０００９】（イ）土地に挿入する部分に円錐形の錐脚を持っているので、地面に食い込み易い。鋼管の切り口を保護し、土砂の侵入を防ぐ（ロ）頂部にキャップを持つので、槌打しても鋼管が潰れたり、変形したり、裂けたりしない。(A) Since the portion to be inserted into the land has a conical pyramid, it is easy to bite into the ground. It protects the cut end of the steel pipe and prevents the intrusion of soil and sand. (B) It has a cap on the top, so the steel pipe will not be crushed, deformed or torn even if it is hammered.

【００１０】（ハ）頂部にキャップを持つので、鋼管内に雨水や塵芥が入る恐れがない。(C) Since the top has a cap, there is no risk of rainwater or dust entering the steel pipe.
