Bridge span and straddle type track beam integrating track beam and evacuation platform
The invention relates to a bridge span integrating a track beam and an evacuation platform and a straddle type track beam, and belongs to the technical field of straddle type track beams. The bridge span integrating the track beam and the evacuation platform comprises a main beam, the main beam is arranged in the bridge direction, and brackets and track beams connected with the main beam are arranged on the two sides of the main beam; the track beams are arranged on the two sides of the main beam in the bridge direction and located at the top of the bracket, and the evacuation platform is located at the top of the main beam and used for forming an evacuation channel; the main beam and the brackets on the two sides are mutually stressed, so that stress is more dispersed and uniform, the span of a bridge is increased under the same deformation requirement condition, the load capacity is improved, and the problems that when an existing rail car runs on the rail beams, the rail beams on the two sides are not related to each other, force transmission is not related to each other, the structure utilization rate is low, and the service life is short are solved. And the bracket can have the function of a maintenance channel, the top of the main beam serves as an evacuation platform, and the utilization efficiency of structural materials is improved.
本申请涉及一种融合轨道梁与疏散平台的桥跨及跨座式轨道梁，属于跨座式轨道梁技术领域，融合轨道梁与疏散平台的桥跨，包括主梁，主梁沿顺桥向设置，主梁的两侧均设有与其连接的托架，轨道梁，轨道梁沿顺桥向设置于主梁的两侧且分别位于托架的顶部，疏散平台，疏散平台位于主梁的顶部，用于形成疏散通道；本申请可以通过主梁和两侧的托架互为受力，使受力更加分散和均匀，在相同形变要求条件下增加桥梁的跨径，提高负载能力，也避免了现有的轨道车在轨道梁上运行时，两侧的轨道梁互不相关，力的传递也互不相关，导致结构利用率低，负载更大，托架可兼顾检修通道功能，主梁顶部作为疏散平台，提高了结构材料的利用效率。
