Continuous track beam structure on high-speed maglev traffic long-span bridge
The invention discloses a continuous track beam structure on a high-speed maglev traffic long-span bridge, and the structure comprises a continuous track beam and a sliding layer which are arranged on a main bridge and approach bridges on two sides; a sliding layer is laid on the lower portion of the continuous track beam, and transverse limiting check blocks are arranged on the two sides of the continuous track beam to limit vertical displacement and transverse displacement of the track beam. Longitudinal and transverse limiting structures are arranged between the continuous track beams and the approach bridges and used for anchoring the continuous track beams. The beneficial effects are that the sliding layer is laid between the main bridge and the continuous track beam, so that the main bridge and the continuous track beam can slide freely along the longitudinal direction, beam end displacement of a large-span bridge caused by temperature change influence is prevented from being transmitted to the track beam, and the problem of over-limit of a beam end stator gap is solved; in addition, the continuous track beam has good force transmission performance, and the longitudinal stability and the transverse stability of the track beam are guaranteed by arranging the concrete check blocks and the limiting structures.
本发明公开一种高速磁浮交通大跨度桥梁上连续式轨道梁结构，包括，设置在主桥和两侧引桥上的连续式轨道梁和滑动层；连续式轨道梁的下部铺设有滑动层，连续式轨道梁的两侧设置有横向限位挡块，限制轨道梁的垂向和横向位移；连续式轨道梁与引桥间设置有纵横向限位结构，锚固连续式轨道梁。有益效果是，由于主桥和连续式轨道梁之间铺设有滑动层，使主桥和连续式轨道梁能够沿纵向自由滑动，因此避免大跨度桥梁受温度变化影响产生的梁端位移传递至轨道梁上，从而解决梁端定子间隙超限的问题；另外，连续式轨道梁具有良好的传力性能，通过设置混凝土挡块及限位结构保证轨道梁的纵、横向稳定性。
