STEEL PLATE FLOOR INSTANT BRIDGE
PROBLEM TO BE SOLVED: To provide a steel plate floor instant bridge capable of suppressing the occurrence of fatigue crack from a welding line at the rib intersecting portion and also of reducing the installation period.MEANS FOR SOLVING THE PROBLEM: A steel plate floor instant bridge 100 has a main girder 40 made of a rolled H-shaped steel, a steel plate floor supporting material 50, and a steel plate floor panel 200. The steel plate floor panel 200 is equipped with a steel plate 11, a longitudinal rib 20 which is a flat plate 21, and a transverse rib 30 having a slit 33 formed therein. At the rib intersecting part, flat plate side surfaces 21s, 21t, and a flat plate lower end surface 21b are welded to slit side edges 33s, 33t, and a slit lower end edge 33b. The steel plate 11, a transverse rib web 31, and a transverse rib lower flange 32 are connected to a supporting material web 51, to a main-girder stiffener 43 and a supporting material stiffener 53 via a splice plate 74, and to a main-girder web 41 via a split tee 60 and a splice plate 74, respectively, by a bolt/nut 80.SELECTED DRAWING: Figure 2
【課題】リブ交差部における溶接線からの疲労亀裂の発生を抑制可能および施工期間を短縮可能な鋼床版インスタント橋を提供する。【課題手段】鋼床版インスタント橋１００は、圧延Ｈ形鋼からなる主桁４０と鋼床版支持材５０と鋼床版パネル２００とを有し、鋼床版パネル２００は鋼板１１と平板２１である縦リブ２０とスリット３３が形成された横リブ３０とを具備し、リブ交差部において、平板側面２１ｓ、２１ｔおよび平板下端面２１ｂは、スリット側縁３３ｓ、３３ｔおよびスリット下端縁３３ｂにそれぞれ溶接接続され、鋼板１１は支持材ウェブ５１に、横リブウェブ３１は主桁スティフナー４３および支持材スティフナー５３にスプライスプレート７４を介して、横リブ下フランジ３２は主桁ウェブ４１にスプリット・ティー６０およびスプライスプレート７４を介して、それぞれボルト／ナット８０によって接続されている。【選択図】図２
