Three-main-truss transverse-connection-free steel truss girder for combined construction of highway and railway
The invention provides a three-main-truss transverse-connection-free steel truss girder for highway-railway combined construction. The highway-railway combined construction three-main-truss transverse-connection-free steel truss girder comprises a lower-layer bridge deck structure, three main trusses and an upper-layer bridge deck structure. The three main trusses are arranged at intervals in the transverse bridge direction, and the lower-layer bridge deck structure is arranged at the bottoms of the three main trusses. The upper-layer bridge deck structure is arranged at the tops of the three main trusses, the upper-layer bridge deck structure comprises an upper-layer bridge deck slab and a plurality of first cross beams arranged at intervals in the longitudinal bridge direction, and the upper-layer bridge deck slab is laid on the first cross beams; each first cross beam comprises two variable cross-section beams, one variable cross-section beam is arranged between every two adjacent main trusses, and the two opposite ends of each variable cross-section beam in the length direction are provided with variable cross-section sections connected with the corresponding main trusses correspondingly. And the section height of the variable cross-section section of each 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. The highway-railway combined construction three-main-truss transverse-connection-free steel truss girder is simple in structure and relatively high in economical efficiency.
本申请提供了一种公铁合建三片主桁无横联钢桁梁，包括：下层桥面结构、三片主桁架和上层桥面结构；三片主桁架沿横桥向间隔设置，下层桥面结构设置在三片主桁架的底部；上层桥面结构设置在三片主桁架的顶部，上层桥面结构包括上层桥面板和多根沿纵桥向间隔设置的第一横梁，上层桥面板铺设在多根第一横梁上；每根第一横梁包括两根变截面梁，每相邻的两片主桁架之间分别设置一根变截面梁，变截面梁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变截面段，每根变截面梁每根变截面梁的变截面段的截面高度均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。本申请的公铁合建三片主桁无横联钢桁梁结构简洁且经济性相对较高。
