Reinforced concrete superposed track beam for guide rail type rubber wheel system
The invention discloses a reinforced concrete laminated track beam for a guide rail type rubber wheel system, and relates to the technical field of urban low-traffic-volume track traffic. The reinforced concrete superposed track beam comprises a plurality of track beam sections, wherein each track beam section comprises two steel longitudinal beams which are oppositely arranged; the first concrete layer is arranged at the top of the steel longitudinal beam; and the second concrete layer is arranged at the bottom of the steel longitudinal beam. The steel-concrete composite beam structure is adopted, the steel longitudinal beams, the first concrete layer and the second concrete layer serve as main stress components, part of the steel longitudinal beams are replaced with the concrete layers, and compared with an existing conventional concrete box beam which is provided with a steel guide rail on the top face, the steel-concrete composite beam structure is small in dead weight and convenient to construct; therefore, the overall rigidity and durability of the track beam are improved.
本发明公开了一种用于导轨式胶轮系统的钢混叠合轨道梁，涉及城市低运量轨道交通技术领域。该钢混叠合轨道梁包括若干个轨道梁节段，轨道梁节段包括两个相对设置的钢纵梁；第一混凝土层，其设置于钢纵梁的顶部；第二混凝土层，其设置于钢纵梁的底部。本发明为钢混叠合梁的结构形式，钢纵梁、第一混凝土层和第二混凝土层作为主要的受力构件，用混凝土层代替部分钢纵梁，比现有的常规混凝土箱梁的顶面设置钢导轨的自重较小，便于施工，比现有的钢导轨梁增加了混凝土结构，从而提高轨道梁的整体的刚度和耐久性。
