The novel bridge structure comprises main beams, end beams, rails and wheel supports, the main beams are sequentially arranged, the end beams are symmetrically arranged at the two ends of the main beams, the rails are symmetrically arranged at the upper ends of the main beams, the wheel supports are arranged at the lower ends of the main beams respectively, and the rails correspond to the wheel supports in the vertical direction. According to the novel bridge structure, the number of welding seams is greatly reduced, stress concentration caused by multiple welding seams is avoided, and therefore it is guaranteed that no welding seam exists at the position of the maximum stress value of the beam, the fatigue life of the beam is prolonged, materials are effectively reduced, cost is reduced, the weight is reduced, machining and assembling procedures are simplified, production efficiency is improved, and the construction period is shortened.

    本发明公开了一种新型桥架结构,新型桥架结构包括主梁、端梁、轨道和车轮支撑,其中:主梁依次排列设置,端梁对称设置在主梁两端,轨道对称设置在主梁上端,车轮支撑分别设置在主梁下端,轨道与车轮支撑上下对应。该新型桥架结构,极大地减少了焊缝数量,避免多焊缝引起的应力集中,从而保证在梁应力最大值处无焊缝,提高了梁的疲劳寿命,有效减少了用料,降低成本,减轻重量,实现简化加工、装配工序,提高生产效率,缩短工期。
