The invention relates to the technical field of emergency bridges, and discloses a slideway structure of a steel-aluminum composite material. The structure comprises an aluminum alloy profile, a high-strength steel tread plate and a shear pin, a slideway is preset on the aluminum alloy profile, a dovetail groove is preset on the tread surface of the slideway, and the high-strength steel tread plate is preset in the dovetail groove; and the high-strength steel tread plate and the aluminum alloy profile are connected through the shear pin. According to the slideway structure provided by the invention, the slideway and the dovetail groove are pre-arranged on the aluminum alloy profile, the high-strength steel tread plate is pre-arranged in the dovetail groove of the slideway tread, and the strength of the slideway tread is improved by adopting a steel-aluminum composite material so that the problem of insufficient strength of the slideway tread is effectively solved; and the weight of the slide way structure is greatly reduced only by prearranging the high-strength steel tread plate on the slide way tread, the overall weight of the bridge is further reduced, the design span of the emergency bridge erected in a horizontally-pushing mode is increased, and the structure is simple in overall structure, reliable in function and easy to achieve.

本发明涉及应急桥技术领域，公开了一种钢铝复合材料的滑道结构，包括铝合金型材、高强钢踏面板和剪力销，所述铝合金型材上预设有滑道，所述滑道的踏面上预设有燕尾槽，所述燕尾槽内预设高强钢踏面板；所述高强钢踏面板和铝合金型材通过剪力销进行连接。本发明提供的滑道结构通过在铝合金型材上预设滑道及燕尾槽，并在滑道踏面的燕尾槽内预设高强钢踏面板，采用钢铝复合材料改善滑道踏面的强度，有效地解决滑道踏面强度不足的问题，仅在滑道踏面上预设高强钢踏面板也大大降低了滑道结构的重量，进而减轻了桥梁的整体重量，从而提高了平推式架设的应急桥的设计跨度，其整体结构简单、功能可靠也易于实现。
