STRUCTURE OF JOINT BETWEEN EXISTING CONCRETE PILE AND PILE HEAD REINFORCEMENT
To provide a new structure for a joint between an existing concrete pile and a pile head reinforcement for which welding work is not required.SOLUTION: The joint structure comprises a plate body (16) that is composed of; one side and the other side that are parallel to each other, the other side being provided with at least one screw hole (21); and a connection section that connects both the sides and is provided with a hole (22). The plate body is placed on the head of an existing concrete pile, and one side (16a) and a connection section (16c) contact the inner circumferential surface and top surface of the existing concrete pile, respectively. Another side (16b) faces and separates from the outer circumferential surface of the existing concrete pile, and a pile head reinforcement (14) passes through the hole of the connection section. Furthermore, the joint structure comprises at least one screw (20) that is screwed into the screw hole in the other side of the plate body and applies pressure to the pile head reinforcement using the plate body as a reaction force support.SELECTED DRAWING: Figure 1
【課題】溶接作業を必要としない、新たな既製コンクリート杭と杭頭補強筋との接合部の構造を提供すること。【解決手段】接合部の構造は、互いに平行な一片部及び少なくとも１つのねじ孔（２１）が設けられた他片部と両片部に連なる、孔（２２）が設けられた連接部とからなる板状体（１６）を備える。板状体は、既製コンクリート杭の頭部上に配置され一片部（１６ａ）及び連接部（１６ｃ）がそれぞれ既製コンクリート杭の内周面及び頂面に接し、他片部（１６ｂ）が既製コンクリート杭の外周面に対して間隔をおいて相対し、また、連接部の孔に杭頭補強筋（１４）が通されている。さらに、板状体の他片部のねじ孔に螺合され板状体を反力支持体として杭頭補強筋に押圧力を及ぼす少なくとも１つのねじ部材（２０）を備える。【選択図】図１
