本発明は、鋼管杭の杭頭部に鋼製の梁部材を接合する鋼管杭の接合構造に関する。 The present invention relates to a joint structure of a steel pipe pile in which a steel beam member is joined to a pile head of a steel pipe pile.
鋼管杭の杭頭部に、この杭頭部上に載置された鋼製の梁部材を接合する鋼管杭の接合構造がある。例えば、特許文献１には、鋼管杭の杭頭部の上面に取り付けられたトッププレート上にＨ形鋼からなる水平梁を載置し、トッププレートに水平梁をボルト接合することにより、鋼管杭の杭頭部に水平梁を接合する杭基礎構造が開示されている。 In the pile head of a steel pipe pile, there is a joint structure of a steel pipe pile in which steel beam members placed on the pile head are joined. For example, in Patent Document 1, a horizontal beam made of H-shaped steel is placed on a top plate attached to the upper surface of a pile head of a steel pipe pile, and the horizontal beam is bolted to the top plate. A pile foundation structure is disclosed in which horizontal beams are joined to the pile heads.
トッププレートは、トッププレートの下面に取り付けられたリブを鋼管杭の杭頭部外周面に現場溶接することによって、鋼管杭の杭頭部に取り付けられている。リブは、予め工場で溶接によりトッププレートの下面に取り付けられている。 The top plate is attached to the pile head of the steel pipe pile by field welding a rib attached to the lower surface of the top plate to the outer periphery of the pile head of the steel pipe pile. The ribs are previously attached to the lower surface of the top plate by welding at a factory.
しかし、この鋼管杭の接合構造では、予め工場で溶接によりトッププレートにリブを取り付けなければならない。また、例えば、現場で、鋼管杭の杭頭部上面にトッププレートを載置した状態でトッププレートの下面にリブを現場溶接しようとすると、現場溶接を上向きの溶接作業により行わなければならないので、この溶接作業が煩雑となる。 However, in this joint structure of steel pipe piles, it is necessary to attach a rib to the top plate by welding in advance in the factory. Also, for example, when on-site welding of a rib to the lower surface of the top plate is carried out while the top plate is placed on the upper surface of the pile head of the steel pipe pile, on-site welding must be performed by an upward welding operation, This welding operation becomes complicated.

第２態様の発明では、力伝達手段によって、梁部材が上方へ引き上げられるのを防ぐことができる。 In the invention of the second aspect, the force transmission means can prevent the beam member from being pulled upward.
第３態様の発明は、第２態様の鋼管杭の接合構造において、前記力伝達手段は、前記杭頭部の外側に、前記杭頭部の上端面と面一に設けられた外プレートと、前記外プレートの下面に設けられた複数のスタッドと、コンクリートにより形成されて前記杭頭部を取り囲み、前記複数のスタッドが埋設されたコンクリート部と、を有する。 The invention of a third aspect relates to the joint structure of steel pipe piles according to the second aspect, wherein the force transmission means is provided outside the pile head and an outer plate provided flush with the upper end face of the pile head; It has a plurality of studs provided on the lower surface of the outer plate, and a concrete part formed of concrete, surrounding the pile head, and in which the plurality of studs are embedded.
第３態様の発明では、コンクリート部に埋設された複数のスタッドによって、梁部材が上方へ引き上げられるのを防ぐことができる。 In the invention of the third aspect, the plurality of studs embedded in the concrete portion can prevent the beam member from being pulled upward.
