Double-layer steel truss girder section and double-layer steel truss girder structure
The invention discloses a double-layer steel truss girder segment and a double-layer steel truss girder structure, and relates to the technical field of bridges, on one hand, the segment comprises an upper-layer bridge deck system, a lower-layer bridge deck system and main trusses welded to the two sides of the upper-layer bridge deck system and the two sides of the lower-layer bridge deck system which are arranged in parallel, and the upper-layer bridge deck system and the lower-layer bridge deck system are connected through the main trusses; the upper-layer bridge deck system adopts a box body structure, and the lower-layer bridge deck system adopts a longitudinal and transverse beam system and is connected through suspenders. On the other hand, the double-layer steel truss girder structure comprises a plurality of the double-layer steel truss girder sections, and the double-layer steel truss girder sections are sequentially spliced in the longitudinal bridge direction. The steel truss girder main truss is of a triangular truss structure and is composed of an upper chord member, a lower chord member, a main truss inclined rod and a connecting inclined rod. In order to omit temporary rod pieces for hoisting the steel truss girder during construction and save steel consumption, joints of the upper chords and the lower chords between the steel truss girder sections are arranged in a staggered manner, and the problem that temporary rod pieces need to be additionally arranged due to the fact that the joints of the upper chords or the lower chords extend too long is solved.
本发明公开了一种双层钢桁梁节段及双层钢桁梁结构，涉及桥梁技术领域，一方面，该节段包括平行布置的上层桥面系、下层桥面系、焊接在上层桥面系和下层桥面系两侧的主桁架，通过主桁架将上层桥面系和下层桥面系连接，上层桥面系采用箱体结构，下层桥面系采用纵横梁体系，上下层桥面系通过吊杆连接。另一方面，该双层钢桁梁结构包括多个上述的双层钢桁梁节段，多个上述双层钢桁梁节段沿纵桥向依次拼接。钢桁梁主桁架采用三角桁结构形式，由上弦杆、下弦杆、主桁斜杆和连接斜杆组成。为取消施工期间吊装钢桁梁的临时杆件，节约钢材用量，各钢桁梁节段之间上弦杆和下弦杆接头位置错开布置，解决了上弦杆或下弦杆接头伸出太长需要增设临时杆件的问题。
