TEMPORARY BOLT-FREE JOINING DEVICE AND METHOD FOR REMOVING TEMPORARY BOLT-FREE JOINING DEVICE
To eliminate the need for replacing a temporary suspended scaffold by preventing the occurrence of interference between a temporary bolt-free joining device and the temporary suspended scaffold when a steel column and a steel beam are connected.SOLUTION: A temporary bolt-free joining device 1 is provided with a plate 10, a pin 12 hanging on the underside of the plate and a pin detachment mechanism 2. The plate 10 is provided with a mounting bolt mounting hole 15 for mounting on a beam steel. The detachment mechanism 2 is provided with a shaft part 21 arranged in a support projection 20 on the upper surface of the plate 10 and a hook-like member 24 energized and rotatable against the outer surface of the pin 12 with the shaft part 21 as its axis. The hook-like member 24 is provided with a hook tip part 241 abutting on the outer surface of the pin 12, an L-shaped part 243 rotatably attached to the shaft part 21, and a connecting pin part 245 connecting the L-shaped part 243 and the hook tip part 241 to form an intermediate part of the hook-like member 24. The hook-like member 24 is bent by turning the hook tip part 241 toward the L-shaped part 243 by the connecting pin part 245 to reduce the turning radius of the whole hook-like member 24.SELECTED DRAWING: Figure 1
【課題】鉄骨柱と梁鉄骨との連結を行う際に仮ボルト不要接合装置と仮設吊り足場との干渉が生じさせず、仮設吊り足場の架け替えを行わなくても済むようにする。【解決手段】プレート１０下面側において垂下するピン１２と、ピンの外れ止め機構２と、を備え、プレート１０は、梁鉄骨に取り付けるための取付ボルト装着孔１５を備え、外れ止め機構２は、プレート１０上面の支持突起２０に配設された軸部２１と、軸部２１を軸にピン１２外側面に向かい付勢され回動可能である鉤状部材２４と、を備え、鉤状部材２４は、ピン１２外側面に当接する鉤先部２４１と、軸部２１に回動可能にとりつけられたＬ字状部２４３と、Ｌ字状部２４３と鉤先部２４１とを連結し鉤状部材２４中間部分となる連結ピン部２４５とを備え、連結ピン部２４５により鉤先部２４１をＬ字状部２４３に向かい回動させて鉤状部材２４を折り曲げ、鉤状部材２４全体の回動半径を小さくする仮ボルト不要接合装置１。【選択図】図１
