Description

本発明は、鋼管杭連結キャップ用吊り具に関し、詳しくは、鋼管杭を下方から挿入可能な鋼管杭挿入筒と該鋼管杭挿入筒より上方に突出した連結軸とを備えた鋼管杭連結キャップを吊り上げる際に装着される鋼管杭連結キャップ用吊り具に関する。   The present invention relates to a hanger for a steel pipe pile connection cap, and more specifically, a steel pipe pile connection cap including a steel pipe pile insertion cylinder capable of inserting a steel pipe pile from below and a connection shaft protruding upward from the steel pipe pile insertion cylinder. The present invention relates to a steel pipe pile coupling cap hanging device that is mounted when lifting.

杭打機による鋼管杭の埋設作業時には、杭打機のリーダに設けられた回転駆動装置からの回転を伝達するために、鋼管杭の頭部に鋼管杭連結用キャップを用いることが広く行われている（例えば、特許文献１，２参照。）。   When embedding steel pipe piles with a pile driver, a steel pipe pile coupling cap is widely used at the head of the steel pipe pile in order to transmit the rotation from the rotary drive unit provided in the leader of the pile driver. (For example, refer to Patent Documents 1 and 2.)

特開２０１３−２１６２号公報JP 2013-2162 A 特開平１１−２５６５７７号公報JP-A-11-256577

しかしながら、特許文献１、２に記載の鋼管杭連結用キャップを立てた状態で吊り上げようとすると、ワイヤを掛けることができるのが、鋼管杭の頭部に設けられた係合突部と係合するための開口部しかなく、形状によっては吊り位置が重心付近又は下側となるため、安定した作業ができなかった。そのため、鋼管杭連結用キャップを横にして吊り上げるという作業を強いられる場合がある。   However, if the steel pipe pile coupling cap described in Patent Documents 1 and 2 is lifted in an upright state, the wire can be hooked with the engagement protrusion provided on the head of the steel pipe pile. However, depending on the shape, the suspending position is near or below the center of gravity, so that stable work cannot be performed. Therefore, the work of lifting the steel pipe pile coupling cap sideways may be forced.

そこで本発明は、鋼管杭連結用キャップを立てた状態で安全に吊り上げることができる鋼管杭連結キャップ用吊り具を提供することを目的としている。   Then, this invention aims at providing the lifting tool for steel pipe pile connection caps which can be safely lifted in the state which stood the steel pipe pile connection cap.

上記目的を達成するため、本発明の鋼管杭連結キャップ用吊り具は、鋼管杭を下方から挿入可能な鋼管杭挿入筒と該鋼管杭挿入筒より上方に突出した連結軸とを備えた鋼管杭連結キャップを吊り上げる際に装着される鋼管杭連結キャップ用吊り具において、該鋼管杭連結キャップ用吊り具は、前記連結軸の上端に載置される天板と、該天板と一体に形成され、前記連結軸の側面をカバーするカバー部と、前記天板より上方に突出する吊持片と、前記天板より下方に突出し、前記連結軸に設けられた貫通孔に挿入されるボス部とを備え、前記カバー部には、前記連結軸の側面に設けられたジョイントピン係合溝に対応する位置にピン挿通孔を設けていることを特徴としている。   In order to achieve the above object, a hanger for a steel pipe pile connection cap according to the present invention comprises a steel pipe pile insertion cylinder capable of inserting a steel pipe pile from below and a connection pipe projecting upward from the steel pipe pile insertion cylinder. In the steel pipe pile connection cap suspension mounted when lifting the connection cap, the steel pipe pile connection cap suspension is formed integrally with the top plate placed on the upper end of the connection shaft. A cover portion that covers a side surface of the connecting shaft; a suspension piece that protrudes upward from the top plate; and a boss portion that protrudes downward from the top plate and is inserted into a through hole provided in the connecting shaft; The cover portion is provided with a pin insertion hole at a position corresponding to a joint pin engagement groove provided on a side surface of the connecting shaft.

本発明の鋼管杭連結キャップ用吊り具によれば、吊持片にワイヤを掛けて吊り上げた際に、カバー部に挿入されたピンで、鋼管杭連結キャップの荷重を受けながら、連結軸の貫通孔に挿入されるボス部が抜け止めとして機能するので、鋼管杭連結キャップを立ち上げた状態のまま、安定して吊り上げることができる。   According to the hanger for a steel pipe pile connection cap of the present invention, when a wire is hung on a suspension piece and lifted, the pin inserted into the cover portion is penetrated by the connection shaft while receiving the load of the steel pipe pile connection cap. Since the boss part inserted into the hole functions as a retaining member, the steel pipe pile coupling cap can be stably lifted while being raised.

前記回転駆動装置６に把持されるロッド８の下端には連結用アタッチメント９が設けられており、この連結用アタッチメント９に鋼管杭連結用キャップ１０を介して鋼管杭１１を連結することによって鋼管杭埋設作業を行う状態となる。   A connecting attachment 9 is provided at the lower end of the rod 8 gripped by the rotary drive device 6, and a steel pipe pile 11 is connected to the connecting attachment 9 via a steel pipe pile connecting cap 10. It will be in a state to bury.

図４及び図５に示すように、鋼管杭連結用キャップ１０は、鋼管杭１１を下方から軸線方向に挿入可能な鋼管杭挿入筒１０ａと、該鋼管杭挿入筒１０ａの上端に固設され、上方に突出して、連結用アタッチメント９の装着孔９ａ内に挿入される連結軸１０ｂとを備えている。連結軸１０ｂの軸線方向には、セメントミルク等を流すための鋼管杭挿入筒１０ａに繋がる貫通孔１０ｃが設けられている。   As shown in FIGS. 4 and 5, the steel pipe pile coupling cap 10 is fixed to the steel pipe pile insertion cylinder 10a capable of inserting the steel pipe pile 11 in the axial direction from below, and to the upper end of the steel pipe pile insertion cylinder 10a. A connecting shaft 10b that protrudes upward and is inserted into the mounting hole 9a of the connecting attachment 9 is provided. In the axial direction of the connecting shaft 10b, a through hole 10c connected to the steel pipe pile insertion cylinder 10a for flowing cement milk or the like is provided.

連結軸１０ｂは略円柱状に形成され、周方向に等間隔に配置された４つの係合凸部１０ｄが設けられており、装着孔９ａには、係合凸部１０ｄ対応する係合凹部９ｂが形成されている。   The connecting shaft 10b is formed in a substantially columnar shape, and is provided with four engaging convex portions 10d arranged at equal intervals in the circumferential direction. The mounting hole 9a has an engaging concave portion 9b corresponding to the engaging convex portion 10d. Is formed.

連結軸１０ｂの側面の対向位置には、ジョイントピン１２，１２を係合するためのジョイントピン係合溝１０ｅ，１０ｅが上下方向に離間して形成され、連結用アタッチメント９の外周側面には、ジョイントピン挿通孔９ｃ，９ｃがジョイントピン係合溝１０ｅに対応する箇所に形成されている。さらに、連結用アタッチメント９の外周側面には、ジョイントピン挿通孔９ｃと直交する位置に、ジョイントピン抜止１３を挿入するための抜止挿通孔９ｄが形成されている。抜止挿通孔９ｄには雌ねじ加工が施され、ジョイントピン抜止１３の雄ねじ部と螺合可能になっている。連結用アタッチメント９のジョイントピン挿通孔９ｃと、鋼管杭連結用キャップ１０のジョイントピン係合溝１０ｅとの位置が合った状態で、ジョイントピン１２を挿入し、ジョイントピン抜止１３によって固定されることで、連結用アタッチメント９と鋼管杭連結用キャップ１０とが連結される。   Joint pin engaging grooves 10e and 10e for engaging the joint pins 12 and 12 are formed at positions opposed to the side surface of the connecting shaft 10b so as to be spaced apart in the vertical direction, and on the outer peripheral side surface of the connecting attachment 9, Joint pin insertion holes 9c, 9c are formed at locations corresponding to the joint pin engaging grooves 10e. Further, a retaining insertion hole 9d for inserting the joint pin retaining hole 13 is formed on the outer peripheral side surface of the connection attachment 9 at a position orthogonal to the joint pin insertion hole 9c. The retaining insertion hole 9d is internally threaded so that it can be screwed into the male threaded portion of the joint pin retaining 13. With the joint pin insertion hole 9c of the connection attachment 9 and the joint pin engagement groove 10e of the steel pipe pile connection cap 10 aligned, the joint pin 12 is inserted and fixed by the joint pin retaining part 13 Thus, the connection attachment 9 and the steel pipe pile connection cap 10 are connected.

回転駆動装置６をリーダ５に沿って下降させると、回転駆動装置６によって回転されるロッド８の回転が、連結用アタッチメント９の係合凹部９ｂと鋼管杭連結用キャップ１０の係合凸部１０ｄとの係合により、鋼管杭連結用キャップ１０に伝達される。さらに、鋼管杭挿入筒１０ａの側面に設けられた開口部１０ｆの回転方向後部側の側面が、鋼管杭１１の頭部外周に設けられた係合突起１１ａを回転方向に押動し、開口部１０ｆの上面が係合突起１１ａの上面を下方に押動することで、鋼管杭１１を回転させながら地中に圧入していくことで埋設していく。   When the rotary drive device 6 is lowered along the leader 5, the rotation of the rod 8 rotated by the rotary drive device 6 causes the engagement concave portion 9b of the connection attachment 9 and the engagement convex portion 10d of the steel pipe pile connection cap 10 to move. Is transmitted to the steel pipe pile coupling cap 10. Furthermore, the side surface on the rear side in the rotation direction of the opening 10f provided on the side surface of the steel pipe pile insertion cylinder 10a pushes the engagement protrusion 11a provided on the outer periphery of the head of the steel pipe pile 11 in the rotation direction, The upper surface of 10f pushes the upper surface of the engaging protrusion 11a downward, so that the steel pipe pile 11 is pressed into the ground while being rotated and buried.

次に、図１及び図２を用いて、鋼管杭連結キャップ用吊り具２０の説明をする。鋼管杭連結キャップ用吊り具２０は、連結軸１０ｂの上端に載置される矩形状の天板２１と、連結軸１０ｂの側面の一部をカバーするカバー部２２と、天板より上方に突出する略三角形状の吊持片２３と、天板２１の裏面より下方に突出し、連結軸１０ｂに設けられた貫通孔１０ｃに挿入される円柱状のボス部２４とを備えている。 Next, the hanger 20 for steel pipe pile connection caps will be described with reference to FIGS. 1 and 2. The steel pipe pile connection cap hanger 20 has a rectangular top plate 21 placed on the upper end of the connection shaft 10b, a cover portion 22 that covers a part of the side surface of the connection shaft 10b, and projects upward from the top plate. And a cylindrical boss portion 24 that protrudes downward from the back surface of the top plate 21 and is inserted into a through hole 10c provided in the connecting shaft 10b.

カバー部２２は、天板２１よりＬ字状に折り曲げられて形成される矩形状のカバー板２２ａと、カバー板２２ａの両端部にそれぞれ溶接される一対の側板２２ｂ，２２ｂとからなり、断面平面視コ字状に形成されている。各側板２２ｂは、側面視略台形状に形成されており、天板側の辺が鋼管杭連結キャップ側の辺よりも長く形成されている。   The cover portion 22 includes a rectangular cover plate 22a formed by being bent into an L shape from the top plate 21, and a pair of side plates 22b and 22b welded to both ends of the cover plate 22a, respectively. It is formed in a U-shape. Each side plate 22b is formed in a substantially trapezoidal shape in side view, and the side on the top plate side is formed longer than the side on the steel pipe pile connection cap side.

一対の側板２２ｂ，２２ｂには、連結軸１０ｂの側面に設けられたジョイントピン係合溝１０ｅ（本形態例では、下方側に位置するジョイントピン係合溝１０ｅ）に対応する位置にピン挿通孔２２ｃが設けられている。ピン挿通孔２２ｃに挿入されたピン３０は、ジョイントピン係合溝１０ｅと係合し、ピン３０の基端部の鍔３０ａと先端部のピン孔３０ｂに挿入されたβピン３１とで抜け止めされる。このようにして、鋼管杭連結キャップ用吊り具２０は鋼管杭連結キャップ１０に装着される。   The pair of side plates 22b, 22b has pin insertion holes at positions corresponding to joint pin engagement grooves 10e (in this embodiment, the joint pin engagement grooves 10e located on the lower side) provided on the side surface of the connecting shaft 10b. 22c is provided. The pin 30 inserted into the pin insertion hole 22c is engaged with the joint pin engaging groove 10e, and is prevented from coming off by the flange 30a at the proximal end portion of the pin 30 and the β pin 31 inserted into the pin hole 30b at the distal end portion. Is done. In this way, the steel pipe pile connection cap suspension 20 is attached to the steel pipe pile connection cap 10.

この状態で、吊持片２３のワイヤ係合孔２３ａにワイヤを掛けて吊り上げると、鋼管杭連結キャップ１０の荷重をピン３０で受けながら、連結軸１０ｂの貫通孔１０ｃにボス部２４が挿入されているために抜け止めとして機能するので、鋼管杭連結キャップ１０を立ち上げた状態のまま、安定して吊り上げることができる。   In this state, when a wire is hung by lifting the wire engaging hole 23a of the suspension piece 23, the boss portion 24 is inserted into the through hole 10c of the connecting shaft 10b while receiving the load of the steel pipe pile connecting cap 10 with the pin 30. Therefore, the steel pipe pile coupling cap 10 can be stably lifted with the steel pipe pile coupling cap 10 raised.
