JOINT METAL FITTING
To provide a robust and strong joint metal fitting by remarkably simplifying a structure without impairing a function of the joint metal fitting and applying a small amount of processing to a material or a member by using a low-cost commercial material or a commercial member.SOLUTION: A joint metal fitting for concrete structure comprises: an insert anchor 1 having a female screw 2 at a front end side and a rear end side formed in a substantially Y shape; a male metal fitting M formed of a pin bolt 4 whose rear end side is screwed into the female screw 2 and which has a substantially frustum-shaped head part 6 at a front end side; and in a steel pipe 8 having an inner diameter capable of tightly loosely inserting the head part 6 of the pin bolt 4, a female metal fitting F of a steel pipe 8 formed by cutting and raising a locking piece 9 locking a bottom surface of the head part 6 as a stopper in a flap shape toward the inside of the steel pipe 8, when an effective part including the head part 6 of the pin bolt 4 is inserted.SELECTED DRAWING: Figure 3
【課題】 継手金具の機能を損なうことなく構造を著しく簡素化し、また、低コストの市販材料、市販部材を使用してその材料や部材に多少の加工を施すだけで、堅牢で強固な継手金具を提供する【解決手段】 先端側に雌ネジ２を有し後端側が略Ｙ状に形成されたインサートアンカー１と、前記雌ネジ２に後端側が、螺合され先端に略錐台状の頭部６を有するピンボルト４により形成したオス金具Ｍ、及び前記ピンボルト４の頭部６を密に遊挿できる内径を有する鋼管８であって、前記ピンボルト４の頭部６を含む有効部分を挿入したとき、その頭部６の底面が抜け止めとして掛止される掛止片９を当該鋼管８の内側に向けてフラップ状に切り起した鋼管８によるメス金具Ｆによりコンクリート構造物用の継手金具を形成する。【選択図】図３
