Tensile device for side piers and auxiliary piers of large-span bridge
The utility model discloses a tensile device for side piers and auxiliary piers of a large-span bridge. The tensile device comprises a main beam, piers, a bearing platform, a support, a balance inhaulcable device and a prestressed steel beam device, a one-way pressed support is arranged between the main beam and the tops of the bridge piers, and the main beam and the bridge piers are connected through a vertically-arranged balance inhaul cable device to balance the uplift force of the main beam at the bridge piers; the bridge piers are of concrete structures, and the bridge piers and the bearing platform are connected through a vertically-arranged prestress steel beam device, so that concrete on the bridge piers is in a pressed state. It is guaranteed that the side piers and the auxiliarypiers of the large-span bridge do not generate negative reaction force, support disengaging is avoided, and safe operation of a large-span bridge structure is guaranteed; the structure is simple, thebalance weight of the main beam at the pier is effectively reduced or the balance weight of the main beam is canceled, and good economic performance and popularization value are achieved.
一种大跨度桥梁边墩、辅助墩的抗拉装置，包括主梁、桥墩、承台、支座、平衡拉索装置、预应力钢束装置；主梁和桥墩的顶部之间设置单向受压的支座，主梁和桥墩通过竖向设置的平衡拉索装置相连接来平衡桥墩处的主梁上拔力；桥墩为混凝土结构，桥墩和承台通过竖向设置的预应力钢束装置相连接，使得桥墩上的混凝土处于受压状态。本发明保证了大跨度桥梁的边墩、辅助墩不产生负反力，避免支座脱空，确保大跨度桥梁结构的安全运营；构造简单，有效减小了桥墩处主梁的配重量或取消主梁配重，具有很好的经济性能和推广价值。
