Cross beam structure for suspended monorail double-curve track beam
The invention discloses a cross beam structure for a suspended monorail double-curve track beam, which comprises track beams arranged on two sides of the suspended monorail double-curve track beam, and each track beam is a steel structure track beam with an open thin-wall section, and is characterized in that a cross beam is arranged between the track beams on the two sides of the suspended monorail double-curve track beam, web plates of the cross beams are aligned with transverse stiffening ribs of the track beam, top plates of the cross beams are aligned with top plates of the track beam, bottom plates of the cross beams are aligned with bottom plates of the track beam, and variable-height transition sections are arranged at the tops of the transverse stiffening ribs on the outer side ofthe track beam and connected with the top plates of the cross beams. According to the cross beam and the connecting structure thereof, bending and torsional deformation of the left line track beam and the right line track beam of the curve section can be restrained, structural stress is uniform, deformation is coordinated, and therefore the vertical displacement and torsion angle of the track beams are greatly reduced, the applicable span of the curve track beams is increased, and the smoothness and comfort of a train running on the curve section are improved.
本发明公开一种用于悬挂式单轨双线曲线轨道梁的横梁构造，悬挂式单轨双线曲线轨道梁包括设于两侧的轨道梁，所述轨道梁为开口薄壁截面的钢结构轨道梁，其特征在于所述两侧轨道梁之间设置横梁,横梁的腹板与轨道梁横向加劲肋对齐，横梁的顶板与轨道梁顶板对齐，横梁的底板与轨道梁底板对齐，轨道梁外侧的横向加劲肋顶部设变高度过渡段与横梁顶板连接。本发明的横梁及其连接构造可约束曲线段左线、右线轨道梁的弯扭变形，使结构受力均匀，变形协调，从而大幅减小轨道梁的竖向位移和扭转角，增加曲线轨道梁的适用跨径，提高列车在曲线段行驶的平顺性和舒适性。
