Double-layer steel truss girder bridge arched girder combination section structure and construction technology thereof
The invention relates to the technical field of arched girder combination structures, in particular to a double-layer steel truss girder bridge arched girder combination section structure and a construction technology thereof.The double-layer steel truss girder bridge arched girder combination section structure comprises a vertical plate, a gusset plate is installed on the base face of the vertical plate, a first transverse partition plate is installed on the outer wall of the gusset plate, and a groove is formed in the outer wall of the first transverse partition plate; a second transverse partition plate is installed on one side of the first transverse partition plate and located on the outer wall of the vertical plate, and a fixing groove is formed in the outer wall of the second transverse partition plate. According to the method, modeling and three-dimensional lofting are conducted on the arched girder combination section through the BIM technology, the machining precision of the arched girder combination section is guaranteed, and bolt hole forming is accurate; submerged-arc welding and manual welding are combined on the arched girder combination section, the arched girder combination section is welded by adopting a method of turning over on a rack for multiple times, and the problem that the welding quality is difficult to control in a traditional method is solved; positioning control points are welded on the arched girder combination section before the arched girder combination section leaves a factory, and a total station is adopted to perform multi-point positioning on the arched girder combination section on site, so that accurate installation is ensured.
本发明涉及拱梁结合结构技术领域，具体为双层钢桁梁桥拱梁结合段结构及其施工工艺，包括竖板，所述竖板的基面上安装有节点板，所述节点板的外壁上安装有第一横隔板，所述第一横隔板的外壁上开设有凹槽，所述第一横隔板的一侧且位于竖板的外壁上安装有第二横隔板，所述第二横隔板的外壁上开设有固定槽；本发明通过BIM技术对拱梁结合段进行建模和三维放样，保证拱梁结合段加工精度，螺栓制孔准确；通过在拱梁结合段上焊接组合了埋弧焊和手工焊，采用在台架上多次翻身的方法焊接拱梁结合段，克服了传统方法焊接质量难以控制问题；通过拱梁结合段出厂前在结合段上焊接定位控制点，现场采用全站仪对拱梁结合段进行多点定位，保证安装准确。
