Suspension type monorail open box type track beam
The invention relates to the technical field of bridge engineering, and provides a suspension type monorail open box type track beam which comprises two bottom plates, a first closed box type and a second closed box type which are respectively and vertically arranged on the two bottom plates, a third closed box type is arranged between the ends, away from the bottom plate, of the first closed boxtype and the second closed box type, and the first closed box type and the second closed box type are each provided with a part for being in contact with a guide wheel. And the first closed box type,the second closed box type and the third closed box type form a closed-loop structure. The track beam is composed of the three closed box types, the three closed box types form a closed-loop structure, stress flow forms a complete closed loop, compared with an open section, the torsional strength of the section of the structure is greatly improved and is about ten times or above that of the open section, deformation caused by torsion is remarkably reduced, and a guarantee is provided for improving the train running comfort.
本发明涉及桥梁工程技术领域，提供了一种悬挂式单轨开口箱型轨道梁，包括两块底板，每一所述底板上具有供走行轮接触的部位，还包括于两块所述底板上分别立设的第一闭口箱型和第二闭口箱型，所述第一闭口箱型与所述第二闭口箱型远离所述底板的端部之间设有第三闭口箱型，所述第一闭口箱型和所述第二闭口箱型均具有供导向轮接触的部位；所述第一闭口箱型、所述第二闭口箱型以及所述第三闭口箱型形成闭环结构。本发明通过三个闭口箱型组成的轨道梁，且三者形成闭环结构，使得应力流也形成完整闭环，相对于开口截面，该结构的截面抗扭强度大幅提高，约为开口截面的十倍以上，显著降低扭转引起的变形，为提高列车行驶舒适性提供保障。
