FLOOR SLAB REPLACEMENT METHOD AND STEEL GIRDER CONSTRUCTION DEVICE
To optimize an upper surface and corners of a steel girder after an existing floor slab has been removed.SOLUTION: A floor slab replacement method includes: an existing floor slab removal step (S1) of removing an existing floor slab 2 from a steel girder 1; a steel girder processing step (S11) of processing the steel girder 1 from which the existing floor slab 2 has been removed; and a new floor slab installation step (S3) of installing a new floor slab 15 on the steel girder 1 that has undergone the processing. The steel girder processing step (S11) includes applying surface preparation processing to an upper surface 1a of the steel girder 1 (the upper surface 1a of an upper flange 1f of the steel girder 1) and/or applying chamfering processing to corners 6, 7 of the steel girder 1 (the corners 6, 7 of the upper flange 1f of the steel girder 1).SELECTED DRAWING: Figure 2
【課題】既設床版が撤去された後の鋼桁の上面や角部の最適化を図る。【解決手段】床版架け替え方法は、既設床版２を鋼桁１から撤去する既設床版撤去工程（Ｓ１）と、既設床版２が撤去された鋼桁１に処理を施す鋼桁処理工程（Ｓ１１）と、この処理が施された鋼桁１上に新設床版１５を設置する新設床版設置工程（Ｓ３）と、を含む。鋼桁処理工程（Ｓ１１）は、鋼桁１の上面１ａ（鋼桁１の上フランジ１ｆの上面１ａ）にケレン処理を施すこと、及び／又は、鋼桁１の角部６，７（鋼桁１の上フランジ１ｆの角部６，７）に面取り処理を施すことを含む。【選択図】図２
