Construction method for steel-concrete combined section of railway hybrid beam with steel truss
The invention belongs to the technical field of railway bridge construction, and particularly relates to a railway hybrid beam steel-concrete combined section construction method with a steel truss, which comprises the following steps: S1, manufacturing a steel truss and a steel outrigger; s2, before the concrete beam is poured, the steel truss is pre-buried to the end of the concrete beam, and the concrete beam is poured and maintained; s3, after the concrete beam reaches the design strength, the steel beam is hoisted to the design height; s4, the steel beams and the concrete beams are fixed through the steel trusses and the steel outriggers; and S5, a joint between the concrete beam and the steel beam is poured, a wet connection section is formed, and after the wet connection section reaches the design strength, steel-concrete combined section construction is completed. The steel outriggers and the steel trusses are adopted as temporary fixing devices for steel-concrete combined section construction, the positioning accuracy of the hoisting steel beams is greatly improved, and the height difference between the concrete beams and the steel beams is small; after wet connection section concrete is poured, the steel truss serves as a permanent device to be left in the concrete, and large deformation is not prone to being generated between the concrete beam and the steel beam.
本发明属于铁路桥梁施工技术领域，尤其涉及一种带钢桁架的铁路混合梁钢混结合段施工方法，包括如下步骤：S1、制作钢桁架和钢挑梁；S2、混凝土梁浇筑前，预埋钢桁架至混凝土梁端部，浇筑混凝土梁并养护；S3、混凝土梁达到设计强度后，吊装钢梁至设计高度；S4、通过钢桁架和钢挑梁使钢梁与混凝土梁固定；S5、浇筑混凝土梁与钢梁之间接缝，形成湿接段，湿接段达到设计强度后，完成钢混结合段施工。本发明采用钢挑梁和钢桁架作为钢混结合段施工临时固定装置，大大提高了吊装钢梁定位的精准性，混凝土梁与钢梁之间高差小；浇筑湿接段混凝土后，钢桁架作为永久装置留在混凝土中，混凝土梁与钢梁之间不容易产生较大的变形。
