Steel structure arch rib structure, half-through steel arch bridge and construction and design method
The invention relates to a steel arch bridge, in particular to a steel structure arch rib structure, a half-through steel arch bridge and a construction and design method. The steel structure arch rib structure comprises an arched first steel truss, the outer side of the first steel truss is coated with a first steel-encased box, and the first steel-encased box is fixedly connected with the first steel truss. According to the steel structure arch rib structure, the first steel truss is constructed firstly, then the first steel-encased steel box is constructed, the first steel truss is used for supporting part of the weight of the first steel-encased steel box, the stress requirement of construction equipment can be effectively lowered, and the construction efficiency can be improved under the condition that existing construction conditions and equipment are not changed or slightly lifted. The reasonable structure and safe construction of the key structure of the steel structure arch rib construction of the kilometer-scale span steel arch bridge are achieved, compared with a single steel truss, the stress requirement for all sectional material pieces on the steel truss is lowered, the difficulty of special customization and construction of the steel truss is lowered, and compared with a single steel box arch, the construction cost is lowered. The construction period risk and the construction cost can be reduced.
本发明涉及一种钢拱桥，特别是钢结构拱肋构造、中承式钢拱桥、施工及设计方法。其中钢结构拱肋构造包括呈拱形的第一钢桁架，第一钢桁架外侧包覆有第一外包钢箱，第一外包钢箱与第一钢桁架固定连接。本申请的钢结构拱肋构造，先施工第一钢桁架，之后施工第一外包钢箱利用第一钢桁架来支撑部分第一外包钢箱重量，能够有效降低施工设备受力需求，能够以现有施工条件及设备不变或略微提升的情况下，实现千米级跨径钢拱桥的钢结构拱肋构造这个关键结构的合理结构与安全建造，相比单一钢桁架来说降低对钢桁架上的各个型材件受力要求，以降低其特殊定制的难度及施工难度，相对于单一钢箱拱来说，能够降低施工期风险和施工成本。
