FASTENING STRUCTURE OF PLATE MATERIAL
To provide a fastening structure of a plate material which can insert a bolt into a bolt insertion hole by correcting a displacement by an easy operation even if the displacement occurs at a center position of the bolt insertion hole when superimposingly bolt-joining two pieces of the plate materials.SOLUTION: A fastening structure of a plate material is constituted of a pile head plate 11 joined to a head of a foundation pile 1, a base plate 21 joined to a lower end part of a steel column 2, and bolts 4 and nuts 5 which are screwed to each other while making washers 3A, 3B interposed therebetween. The washers 3A, 3B have forms which are obtained by forming a leg part 32 which is smaller than a seat part 31 in a diameter at a backface side of the circular plate-shaped seat part 31 coaxially therewith. The leg part 32 is rotatable in a state of being fit into bolt insertion holes 12, 22, and bolt receiving holes 33 having inside diameters which are made to coincide with axial dimensions of the bolts 4 penetrate the seat part 31 and the leg part 32 in an eccentric position with respect to the circular plate-shaped seat part 31. By rotating a pair of the washers 3A, 3B, centers of the bolt receiving holes 33 are made to coincide with each other.SELECTED DRAWING: Figure 1
【課題】２枚のプレート材を重ねてボルト接合する際に、ボルト挿通孔の中心位置にずれがあっても簡単な操作でずれを修正してボルトを挿通することができ、支圧によるせん断力の伝達が十分に行われるプレート材の締結構造を提供すること。【解決手段】基礎杭１の頭部に接合された杭頭プレート１１と、鉄骨柱２の下端部に接合されたベースプレート２１と、座金３Ａ，３Ｂを介在させて螺合するボルト４及びナット５の各部材で構成され、座金３Ａ，３Ｂは、円板状の座部３１の背面側に座部３１より小径の脚部３２を同心状に形成した形態をなし、脚部３２がボルト挿通孔１２，２２に嵌合した状態で回転可能であり、ボルト４の軸径に合わせた内径のボルト受入れ孔３３が円板状の座部３１に対して偏心位置で座部３１と脚部３２を貫通したもので、これら一対の座金３Ａ，３Ｂを回転することで互いのボルト受入れ孔３３の中心を一致させる。【選択図】図１
