Cable-stayed bridge girder connected with anchor pulling plate
The invention relates to the field of bridge structure buildings, and particularly relates to a cable-stayed bridge girder connected with an anchor pulling plate. The cable-stayed bridge girder comprises a steel-concrete composite beam and an anchor pulling plate assembly which are connected, the steel-concrete composite beam comprises a top plate and an upper web which are connected, the anchor pulling plate assembly comprises the anchor pulling plate, the upper web is vertically connected to the end of the top plate, and the upper web extends out of the top plate and is in butt joint with the anchor pulling plate. According to the cable-stayed bridge girder, the structural form, stress, wind resistance and the like of the anchoring plate and the steel-concrete composite beam are comprehensively considered; the section form of the main beam structure, the connection mode of the main beam structure and the anchor pulling plate and the like are optimally designed; therefore, the adverseconditions of material waste, large construction hoisting weight and the like can be avoided, meanwhile, under the condition that the wind resistance of the bridge is guaranteed, the steel consumption and the construction cost are saved, butt weld joints are adopted between the anchor pulling plates and the upper web of the main beam, and the advantages of being better in stress, easier to guarantee the welding quality and the like are achieved.
本发明涉及桥梁结构建筑领域，具体涉及一种与锚拉板连接的斜拉桥主梁，包括相连接的钢‑混结合梁和锚拉板组件，钢‑混结合梁包括相连接的顶板和上腹板，锚拉板组件包括锚拉板，上腹板竖向连接在顶板端部，且上腹板延伸超出顶板并与锚拉板相互对接。本发明综合考虑锚拉板与钢‑混结合梁的构造形式、受力及抗风性能等，对主梁结构的截面形式以及与锚拉板的连接方式等方面进行优化设计，这样可以避免造成材料的浪费、施工吊装重量大等不利情况，同时在保证桥梁抗风性能的条件下，节约了用钢量和工程造价，同时在锚拉板和主梁上腹板之间采用对接焊缝，具有受力更好、焊接质量更容易保证等优点。
