Fabricated steel guide beam structure for incremental launching construction of steel structure bridge
The invention discloses a fabricated steel guide beam structure for incremental launching construction of a steel structure bridge. The device comprises a steel guide beam, a parallel connection inclined strut, a flange plate and a bolt group. The pushing construction assembly type steel guide beam structure has four control key points, namely, the distance between guide beam structures of each truss of a single cantilever is adjustable, the distance between standard sections between transverse guide beams is adjustable, the splicing length in the bridge direction is adjustable, and all components are connected in a bolted mode through flanges and steel plate bolts. In order to reduce the dead weight of the guide beam and meet the pushing construction requirements of the steel beam, the I-shaped guide beam is designed and adopted, the root is welded with the steel beam, and the front end of the guide beam is of a pier-passing design boss structure. Before the guide beams are installed, the distance between the guide beams on the single side and the single side is adjusted according to the width of a steel beam web or a box chamber, the guide beams are connected through steel pipe flanges in a parallel connection mode, a first section is welded to base metal through a gantry or a truck crane, and the number of the guide beam sections of the middle section is arranged according to the span distance of pushing via holes; the guide beam trusses are in butt joint through flange head steel pipe bolts, and the guide beam segments are in rapid butt joint through high-strength bolts after holes are formed in externally-attached steel plates. The fabricated guide beam is suitable for incremental launching construction processes of various steel structures, steel-concrete structures, steel-HUPC structures and other different structures and different linear conditions. The fabricated guide beam structure is good in mechanical property, high in fabricated degree, safe in construction, reusable and high in turnover efficiency, and the engineering cost is effectively reduced.
公开发明了一种钢结构桥梁顶推施工装配式钢导梁结构。所述装置包括：钢导梁、平联斜撑、法兰盘、螺栓群。顶推施工装配式钢导梁结构存在四个控制关键点：一是单个悬臂每榀导梁结构间距可调、二是横向导梁间标准节段且间距可调、三是顺桥向拼装长度可调、四是所有构件均采用法兰和钢板螺栓栓接。为降低导梁自重，并满足钢梁顶推施工要求，设计采用工字型导梁，由根部与钢梁焊接，导梁前端为过墩设计凸台结构。导梁安装前，根据钢梁腹板或箱室宽度调节好单边单侧导梁间距，导梁与导梁间平联进行钢管法兰连接，利用龙门或汽车吊将首节段与母材焊接，根据顶推过孔跨径间距，布置好中间段导梁节段数量，导梁榀与榀之间采用法兰头钢管螺栓对接，导梁节段与节段之间采用外贴钢板开孔后高强螺栓快速对接。本装配式导梁适用于各种钢结构、钢混结构、钢‑HUPC结构等不同结构和不同线性情况顶推施工工艺。本装配式导梁结构，力学性能良好，装配式程度高，施工安全，可以重复利用，周转效率高，有效降低了工程成本。
