Double-layer steel truss girder structure
The invention relates to a double-layer steel truss girder structure which comprises an upper-layer bridge deck system and a lower-layer bridge deck system with box-shaped sections, main trusses are connected to the two sides of the upper-layer bridge deck system and the two sides of the lower-layer bridge deck system and comprise upper chords and lower chords, the upper chords are connected to the two sides of the upper-layer bridge deck system, and the lower chords are connected to the two sides of the lower-layer bridge deck system. First tuyere assemblies are arranged at the joints of the upper-layer bridge deck system and the upper chords on the two sides, and second tuyere assemblies are arranged at the joints of the lower-layer bridge deck system and the lower chords on the two sides. The bridge deck structure has the beneficial effects that 1, through the structures of the upper-layer bridge deck system, the lower-layer bridge deck system, the first tuyeres and the second tuyeres, the overall aerodynamic configuration is improved, the overall torsional rigidity is improved, and therefore the overall wind-resistant stability is improved; the upper-layer bridge deck system and the lower-layer bridge deck system are arranged to be of a closed box structure, passing of maintainers is facilitated, and maintenance convenience is enhanced; and 3, the bridge deck system with the closed box structure improves the torsional rigidity of the stiffening beams and the vertical rigidity of the bridge deck, and improves the rigidity uniformity of the bridge deck.
本发明涉及一种双层钢桁梁结构，包括截面呈箱型的上层桥面系及下层桥面系，上层桥面系及下层桥面系两侧连接有主桁架，主桁架包括上弦杆及下弦杆，上弦杆连接于上层桥面系两侧，下弦杆连接于下层桥面系两侧，上层桥面系与两侧的上弦杆连接处设有第一风嘴组件，下层桥面系与两侧的下弦杆连接处设有第二风嘴组件。本发明的有益效果在于：1、通过上层桥面系、下层桥面系、第一风嘴及第二风嘴的结构改善整体的气动外形，提高整体的抗扭刚度，从而提高整体的抗风稳定性；2、通过将上层桥面系及下层桥面系设置成封闭箱结构，方便检修人员通行，增强维护的便捷性；3、封闭箱结构的桥面系，提高加劲梁抗扭刚度和桥面竖向刚度，提高桥面刚度的均匀性。
