Beam-rail integrated track beam
The embodiment of the invention provides a beam-rail integrated track beam. The beam-rail integrated track beam comprises a concrete track plate, a steel box beam and a steel-concrete connecting piece for connecting the concrete track plate and the steel box beam, the steel box beam comprises a bottom plate, a web plate, a cross beam, a web plate top plate and a cross beam top plate, the web plate and the cross beam are both located on the bottom plate, and the bottom plate, the web plate and the cross beam are perpendicular to one another in pairs; the web top plate and the beam top plate are located above the web and the beam respectively, and part of the bottom plate is exposed. According to the embodiment of the invention, the dead weight and section height of the beam structure are obviously reduced by arranging the steel box beam; only the web top plate and the cross beam top plate are arranged, the top plates are close to a beam section compression area under train load, and local instability and cross beam deformation are avoided; the track structure and the steel box girder structure can adopt a factory prefabrication method, so that the working efficiency is improved, and the manufacturing precision is ensured; beam and rail integration is achieved, the advantages of being good in integrity and large in structural rigidity are achieved, and the high-speed running requirement of the maglev train is better met.
本申请实施例提供了一种梁轨一体化的轨道梁。梁轨一体化的轨道梁包括混凝土轨道板、钢箱梁和连接混凝土轨道板、钢箱梁的钢混连接件：其中，钢箱梁包括底板、腹板、横梁、腹板顶板和横梁顶板，腹板和横梁均位于底板上，底板、腹板和横梁之间两两互相垂直，腹板顶板和横梁顶板分别位于腹板和横梁的上方，露出部分底板。本申请实施例通过设置钢箱梁显著降低梁结构的自重和截面高度；仅设置腹板顶板和横梁顶板，在列车荷载下顶板距离梁截面受压区较近，避免了局部失稳，横梁变形；轨道结构与钢箱梁结构可采用工厂预制法，提高工作效率，保证制作精度；梁轨一体化，具有整体性好，结构刚度大的优势，更适应磁浮列车的高速行车需要。
