Tripod bridge
The invention discloses a tripod bridge which is mainly composed of rigid inclined rods (1), abutments (2), a main beam (3) and rigid connecting rods (4). The rigid inclined rods (1) are arranged between bridge spans, the upper ends of the rigid inclined rods (1) are connected, the lower ends of the rigid inclined rods (1) are connected with the abutments (2) respectively, and the rigid inclined rods (1) are fixedly connected with the main beams (3) at the joints. The rigid connecting rod (4) is arranged between the main beam (3) and the rigid inclined rod (1). A stable tripod formed by the rigid inclined rods (1) and the ground is used as a bearing structure of a bridge, and the center point, with the largest deformation, of a main beam is restrained according to the triangle stability principle, so that the center point is close to rigidity; and meanwhile, the two rigid inclined rods (1) are adopted to strongly restrain the main beam (3), so that the calculated span is greatly reduced. According to the structure, the tripod bridge is scientific and reasonable in stress and low in manufacturing cost, has the advantages of high bearing capacity, high rigidity, good stability and the like, and is a novel bridge worthy of popularization and application.
本发明公开了一种三角架桥,主要由刚性斜杆(1)、墩台(2)、主梁(3)、刚性连接杆(4)构成;所述的刚性斜杆(1)布置在桥跨之间,上端相连,下端分别与墩台(2)相接,刚性斜杆(1)与主梁(3)在交接处固结;所述的刚性连接杆(4)布置于主梁(3)与刚性斜杆(1)之间。本发明利用刚性斜杆(1)与大地构成稳定的三角架作为桥梁的承重结构,利用三角形稳定性原理对主梁变形最大的中心点处进行约束,使其接近刚性,同时,采用两根刚性斜杆(1)对主梁(3)进行强有力约束,使计算跨度大幅减小。三角架桥受力科学合理、造价经济,具有承载力高、刚度大、稳定性好等优点,是一种值得推广应用的新型桥梁。
