Cable-stayed bridge box girder and construction method thereof
The invention discloses a cable-stayed bridge box girder and a construction method thereof.The cable-stayed bridge box girder comprises a box girder body, the box girder body is arranged on a bridge pier and a foundation, the box girder body comprises a box girder top plate, a box girder bottom plate and a plurality of inclined rods arranged between the box girder top plate and the box girder bottom plate, and the inclined rods comprise the first inclined rods and the second inclined rods; the first inclined rods and the second inclined rods are fixedly connected between the box girder top plate and the box girder bottom plate and arranged in the bridge direction at intervals. In the bridge direction, the section size of the first inclined rod is larger than that of the second inclined rod, the first inclined rod can be directly supported on a bottom plate, and the pressure of the self weight of the structure is reduced. The cable-stayed bridge beam structure has the advantages that the purposes of effectively transmitting loads, reducing the self weight of the structure and facilitating construction are achieved, and a novel beam structure form is provided for a cable-stayed bridge.
本发明公开了一种斜拉桥箱梁及其施工方法，包括：箱梁主体，所述箱梁主体设于桥墩、基础上，所述箱梁主体包括箱梁顶板、箱梁底板和若干设置在所述箱梁顶板和所述箱梁底板之间的斜杆，所述斜杆包括第一斜杆和第二斜杆，所述第一斜杆和所述第二斜杆均固定连接在所述箱梁顶板和所述箱梁底板之间，且沿顺桥向间隔设置；沿顺桥方向，所述第一斜杆的截面尺寸大于所述第二斜杆的截面尺寸，能够直接支撑于底板，减轻了结构自重的压力。本发明优点是：达到了有效传递荷载、减轻结构自重、便于施工的目的，为斜拉桥提供了一种新颖的梁部结构形式。
