Centering type steel-concrete combined section for hybrid beam cable-stayed bridge and hybrid beam cable-stayed bridge
The invention provides a centering type steel-concrete combined section for a hybrid beam cable-stayed bridge and the hybrid beam cable-stayed bridge. The centering type steel-concrete combined section comprises a web extension section, a bottom plate extension section, a top plate extension section and a bearing plate. The rear ends of the web extension section, the bottom plate extension sectionand the top plate extension section penetrate through a concrete beam end partition plate and extend into a concrete beam; the bearing plate is arranged at a junction of the web extension section, the bottom plate extension section, the top plate extension section and the concrete beam end partition plate; stud connecting pieces are arranged on the two sides of the parts, extending into the concrete beam area, of the web extension section and the bottom plate extension section and the side, making contact with the concrete beam end partition plate, of the bearing plate; T-shaped stiffening ribs are arranged on the inner sides and the outer sides of the web extension section and the bottom plate extension section; and the front ends of the T-shaped stiffening ribs are fixedly connected with the steel beam stiffening ribs in a continuous transition mode, and the rear ends of the T-shaped stiffening ribs are fixedly connected with the bearing plate. By means of the combined section and the bridge, a structural form of a force transmission path and rigidity transition of the steel-concrete combined section can be effectively improved.
本发明提供了一种用于混合梁斜拉桥的对中式钢‑混结合段以及混合梁斜拉桥。该对中式钢‑混结合段包括：腹板延伸段、底板延伸段、顶板延伸段、承压板；腹板延伸段、底板延伸段、顶板延伸段的后端均穿过混凝土梁端隔板伸入混凝土梁中；承压板设置在腹板延伸段、底板延伸段、顶板延伸段与混凝土梁端隔板的交界处；腹板延伸段和底板延伸段伸入混凝土梁区域的部分的两侧以及承压板与混凝土梁端隔板接触的一侧均设置有栓钉连接件；腹板延伸段和底板延伸段的内外两侧均设置有T形加劲肋；T形加劲肋的前端连续过渡与钢梁加劲肋固定连接，后端与承压板固定连接。应用本发明可以有效地改善钢‑混结合段的传力路径与刚度过渡的结构形式。
