ANCHORAGE FITTING FOR BRIDGE FALL PREVENTION DEVICE AND METHOD OF MANUFACTURING THE SAME

PROBLEM TO BE SOLVED: To provide an anchorage fitting for a bridge fall prevention device, which has necessary strength, which dispenses with a burdensome work such as full penetration weld, and which can reduce a manufacturing cost, and a method of manufacturing the anchorage fitting.SOLUTION: An anchorage fitting 1 for a bridge fall prevention device 10 for preventing an upper structure (bridge girder H) of a bridge from falling from a lower structure (abutment B) includes a base plate 2 that is made of a thick-plate steel plate, and a top plate 3 that has a plate surface orthogonal to the base plate 2. The base plate 2 and the top plate 3 are cut out from extremely-thick H-shaped steel, the web of which is almost equal in plate thickness to a flange, and integrally molded.SELECTED DRAWING: Figure 2 【課題】必要な強度を有するとともに、完全溶け込み溶接など手間のかかる作業が必要なく、製作コストを低減することができる落橋防止装置の定着金具及びその製造方法を提供する。【解決手段】橋梁の上部構造体（橋桁Ｈ）が下部構造体（橋台Ｂ）から落下することを防止する落下防止装置１０の定着金具１において、厚板鋼板からなるベースプレート２と、このベースプレート２と直交する板面を有するトッププレート３と、を備え、これらのベースプレート２とトッププレート３とを、ウェブの板厚がフランジの板厚と同程度の極厚Ｈ形鋼から切り出して一体成形する。【選択図】図２
