Steel-concrete combined truss girder for highway-railway combined construction
The embodiment of the invention provides a steel-concrete combined truss girder for highway-railway combined construction. The steel-concrete combined truss girder comprises a lower-layer concrete bridge deck structure, a main truss, an upper-layer bridge deck structure and an auxiliary truss. The upper-layer bridge deck structure comprises an upper-layer bridge deck slab and a plurality of first cross beams; the first cross beam comprises a first variable cross-section beam and two second variable cross-section beams; the first variable cross-section beam is arranged between the two main trusses, first variable cross-section sections connected with the corresponding main trusses are arranged at the two opposite ends of the first variable cross-section beam in the length direction respectively, and the cross-section height of each first variable cross-section section is gradually decreased from the end connected with the corresponding main truss to the end away from the corresponding main truss; a second variable cross-section beam is arranged on the side, away from the first variable cross-section beam, of each main truss, and each second variable cross-section beam is provided with a second variable cross-section section connected with the corresponding main truss. And the section height of the second variable cross-section section of each second variable cross-section beam is gradually reduced from one end connected with the corresponding main truss to one end far away from the corresponding main truss.
本申请实施例提供了一种公铁合建钢混组合桁架梁，包括下层混凝土桥面结构、主桁架、上层桥面结构和副桁架；上层桥面结构包括上层桥面板和多根第一横梁；第一横梁包括第一变截面梁和两根第二变截面梁；第一变截面梁设置在两片主桁架之间，第一变截面梁沿长度方向的相对两端分别具有与对应的主桁架连接的第一变截面段，每个第一变截面段的截面高度从与对应的主桁架连接的一端朝远离对应的主桁架的一端逐渐变小；每片主桁架背离第一变截面梁的一侧分别设置一根第二变截面梁，每根第二变截面梁分别具有与对应的主桁架连接的第二变截面段，每根第二变截面梁的第二变截面段的截面高度从与对应的主桁架连接的一端朝远离对应的主桁架的一端逐渐变小。
