TEMPORARY FIXTURE FOR FLOOR SLAB ERECTION
To provide a temporary fixture for floor slab erection having versatility to usable without depending on the specifications of the floor slab or main girder, and which can shorten the working time required for temporary fixing.SOLUTION: A temporary fixture 1 for floor slab erection temporarily fixes a floor slab placed on a main girder of a bridge. The temporary fixture 1 for floor slab erection includes: a fixing part 10 fixed to the floor slab through an insert nut embedded in the floor slab; and a body part 20 attached to the fixing part 10. The body part 20 comprises: floor slab arms 22a, 22b having a floor slab pressing part 22c for pressing the lateral face of an overhang part of the floor slab; main girder arms 21a, 21b having a main girder pressing part 21c for pressing the flange of the main girder; a main shaft 23 for supporting the floor slab arms 22a, 22b and the main girder arms 21a, 21b so as to be rotatable around the same axis; and a rotation mechanism for rotating the floor slab arms 22a, 22b and the main girder arms 21a, 21b in mutually opposite directions.SELECTED DRAWING: Figure 2
【課題】床版や主桁の仕様に依らずに使用可能な汎用性を有し、仮固定に要する作業時間の短縮が可能な床版架設用仮固定金具を提供する。【解決手段】床版架設用仮固定金具１は、橋梁の主桁に載せられた床版を仮固定するための床版架設用仮固定金具１であって、床版に埋め込まれたインサートナットを介して床版に固定される固定パーツ１０と、固定パーツ１０に取り付けられる本体パーツ２０と、を備える。本体パーツ２０は、床版の張り出し部側面を押圧する床版押圧部２２ｃを有する床版アーム２２ａ、２２ｂと、主桁のフランジを押圧する主桁押圧部２１ｃを有する主桁アーム２１ａ、２１ｂと、床版アーム２２ａ、２２ｂ及び主桁アーム２１ａ、２１ｂを同一軸回りに回動可能に支持する主軸２３と、床版アーム２２ａ、２２ｂ及び主桁アーム２１ａ、２１ｂを互いに逆向きに回動させる回動機構と、を有する。【選択図】図２
