STRUCTURE OF CONNECTION PART
To provide a structure of a connection part capable of suppressing the occurrence of pin dropping and loosening.SOLUTION: In a bridge constructed by repeating a step of installing a beam structure to overhang in a cantilever shape and a step of driving a support pile of the bridge by using the beam structure overhanging in the cantilever shape, a structure 10 of a connection part for mutually connecting the adjacent beam structures is provided; the connection part is constituted by the male-female fitting of a male fitting member 16 and a female fitting member 12, and includes through-holes 18, 20 provided in the male fitting member 16 and the female fitting member 12, and a pin 22 inserted into the through-holes 18, 20; a screw part 26 is provided on the front end side of a shaft part 28 of the pin 22, a head part 30 having a diameter larger than that of the shaft part 28 is provided on the rear end side, and a nut 34 for fixing the male fitting member 16 and the female fitting member 12 is screwed to a screw part 26.SELECTED DRAWING: Figure 1
【課題】ピンの脱落やゆるみの発生を抑えることができる連結部の構造を提供する。【解決手段】片持ち状に張り出すように梁構造を設置する工程と、片持ち状に張り出した梁構造を利用して橋梁の支持杭を打設する工程と、を繰り返して構築される橋梁において、隣接する梁構造を相互に連結するための連結部の構造１０であって、連結部は、オス嵌合部材１６とメス嵌合部材１２とのオスメス嵌合により構成され、オス嵌合部材１６およびメス嵌合部材１２に設けられた貫通孔１８、２０と、貫通孔１８、２０に挿入されるピン２２とを備え、ピン２２の軸部２８の前端側にはねじ部２６が設けられ、後端側には軸部２８より大径の頭部３０が設けられ、ねじ部２６には、オス嵌合部材１６とメス嵌合部材１２を固定するためのナット３４が螺合している。【選択図】図１
