Combined steel bridge structure and machining method thereof
The invention relates to the technical field of bridge construction, and discloses a combined steel bridge structure which comprises a plurality of bridge units transversely connected end to end. Each bridge unit comprises a left box girder, a right box girder and a central H-shaped steel cross beam used for longitudinally connecting the left box girder and the right box girder. Each bridge unit is high in the middle and low in the two sides, and 1%-5% gradient phi is arranged from the connecting position to the two sides of the left box girder and the right box girder. Each of the left box girder and the right box girder comprises a plurality of box girder units and H-shaped steel cross beams for longitudinally connecting two adjacent box girder units. The invention further discloses a machining method of the combined steel bridge structure. The machining method comprises the following steps that S1, the left box girder is manufactured; s2, manufacturing a right box girder; s3, bridge units are manufactured; and S4, the multiple bridge units are connected end to end to form the steel bridge structure. The steel bridge is divided into the units easy to assemble and combine, machining in a factory is facilitated, on-site construction and splicing are facilitated, and the safety performance is high.
本发明涉及桥梁建设技术领域，公开了一种组合式钢桥梁结构，其包括若干个首尾横向相连的桥梁单元。桥梁单元包括左幅箱梁、右幅箱梁以及用于将左幅箱梁和右幅箱梁纵向连接的中心H型钢横梁。桥梁单元中间高两边低，从连接处往左幅箱梁和右幅箱梁两边设有1％至5％的坡度Φ。左幅箱梁、右幅箱梁均包括若干个箱梁单元以及用于将相邻的两箱梁单元纵向连接的H型钢横梁。本发明还公开了一种组合式钢桥梁结构的加工方法，其包括以下步骤：S1、制作左幅箱梁；S2、制作右幅箱梁；S3、制作桥梁单元；S4、将若干个桥梁单元首尾相连形成钢桥梁结构。本发明将钢桥梁分成易于拼装组合单元，不仅便于在工厂内加工，便于现场施工拼接，而且安全性能高。
