Composite beam of railway cable-stayed bridge
The invention relates to the technical field of composite beams of cable-stayed bridges, and discloses a composite beam of a railway cable-stayed bridge. The composite beam comprises a side span beambody and a middle span beam body; a composite section is arranged between the side span beam body and the middle span beam body; the composite section comprises a hollow steel box; one side of the steel box is welded with the middle span beam body; the other side of the steel box is connected with the side span beam body; the side span beam body comprises a concrete panel located above the steel box and a concrete plate located in the steel box; a shearing nail is fixedly connected to the steel box and comprises a nail shaft and a nail body; a nail plate vertically connected with the nail bodyin a sliding mode is welded to the nail shaft; a buffer layer located in the nail body is arranged below the nail plate; the nail body is located in the concrete plate; and the nail shaft is locatedin the concrete panel. The composite beam is simple in structure. According to the composite beam, an acting force borne by the concrete panel can be effectively reduced, the probability of deformation of the concrete panel can be reduced, and the service life of the combined section is prolonged.
本发明涉及斜拉桥的组合梁技术领域，公开了一种铁路斜拉桥的组合梁，包括边跨梁体和中跨梁体，边跨梁体与中跨梁体之间设置有组合段，组合段包括中空的钢箱，钢箱的一侧与中跨梁体焊接，钢箱另一侧与边跨梁体连接；边跨梁体包括位于钢箱上方的混凝土面板和位于钢箱内的混凝土板，钢箱上固定连接有剪切钉，剪切钉包括钉轴和钉体，钉轴上焊接有与钉体竖直滑动连接的钉板，钉板的下方设置有位于钉体内的缓冲层，钉体位于混凝土板内，钉轴位于混凝土面板内。本发明结构简单，能够有效的降低混凝土面板受到的作用力，降低混凝土面板发生形变的几率，延长组合段的使用寿命。
