Overall assembly structure of eccentric half-amplitude steel-concrete combined box girder
The invention relates to an overall assembly structure of an eccentric half-amplitude steel-concrete combined box girder with the length of 32.25 m, the width of 17.8 m and the weight of more than 539 tons. On a long-line-method overall assembly jig frame, a left eccentric half-amplitude section bottom steel girder and a right eccentric half-amplitude section bottom steel girder and two whole-amplitude girder sections at the two ends in the length direction of the left eccentric half-amplitude section bottom steel girder and the right eccentric half-amplitude section bottom steel girder respectively achieve six-section long-line-method overall assembly; and the left eccentric half-amplitude section and the right eccentric half-amplitude section are temporarily connected into a whole through temporary matching pieces, and the matching size between the half-amplitude sections and the overall assembly precision of the half-amplitude sections and the front and back adjacent whole-amplitude sections are guaranteed. The structure has advantages that firstly, the ultra-large eccentric half-amplitude steel-concrete combined girder adopts integral assembly and integral tire ejection so that the problem of tire ejection of an ultra-large and overweight eccentric girder section is solved while the integral manufacturing precision is ensured; secondly, hoisting and overlapping of the large overweight precast concrete bridge deck slab are achieved; thirdly, supporting and transporting of the half-amplitude eccentric steel-concrete combined box girder are achieved, and convenience and rapidness are achieved; and fourthly, the integral manufacturing precision of the eccentric half-amplitude steel-concrete combined box girder is realized.
本发明涉及一种长32.25m，宽17.8m，重量超过539吨的偏心半幅钢混组合箱梁总拼结构，在长线法总拼胎架上，左右偏心半幅节段底部钢梁与其长度方向两端各二个整幅梁段一起实现六个节段长线法总拼，左右偏心半幅节段之间采用临时匹配件临时连接成整体，保证半幅节段相互间的匹配尺寸及半幅节段与前后相临整幅节段的整体总拼精度。优点：一是超大偏心半幅钢混组合梁采用整体总拼、整体出胎，保证整体制造精度的同时，解决了超大、超重偏心梁段的出胎难题；二是实现了大型超重预制混凝土桥面板的吊装和叠合；三是实现半幅偏心钢混组合箱梁的支撑与运输，方便快捷；四是实现偏心半幅钢混组合箱梁的整体制造精度。
