Arch bridge with tie bar cables tensioned transversely
The invention discloses an arch bridge with tie bar cables tensioned transversely. The arch bridge comprises a main arch, a main beam and the tie bar cables, the two ends of each tie bar cable are correspondingly anchored to the two ends of the main arch respectively, transverse tensioning assemblies for applying transverse tensioning force to the tie bar cables are distributed on the tie bar cables in the length direction, and the acting points of the transverse tensioning assemblies are located on the main beam; according to the arch bridge, the cable force of the tie bar cable is actively and transversely tensioned and adjusted, so that the longitudinal tensioning force of the tie bar cable is formed, and the problems that the tensioning space for tensioning the tie bar cable at the end part or inside of the skewback is insufficient and the specification of required equipment such as a jack is too large can be solved; transverse tensioning force is applied through the multiple sets of tensioning assemblies, each set of tensioning assembly only applies small transverse tensioning force, the longitudinal tensioning force of the tie bar cable can be effectively adjusted, and therefore tie bar cable tensioning and cable force adjusting can be flexibly conducted on the tie bar cable at low cost. A uniform, orderly and variable structure can be formed among the transverse tensioning assemblies, the curve plane line shape of the tie bar cable corresponds to the inwards-inclined arch rib, the form is novel, and the appearance is attractive.
本发明公开了一种横向张拉系杆索的拱桥，包括主拱、主梁和两端与主拱的两端分别对应锚固的系杆索，系杆索沿长度方向分布有对其施加横向张拉力的横向张拉组件，所述横向张拉组件的着力点位于主梁；本发明对系杆索索力进行主动的横向张拉和调节，从而形成系杆索的纵向张拉力，能够克服在拱座端部或内部张拉系杆索张拉空间不足以及所需千斤顶等设备规格太大的难题；通过多组张拉组件实施横向张拉力，每组张拉组件仅施加较小的横向张拉力，即可有效调整系杆索的纵向拉力，以实现对系杆索低成本、灵活的进行系杆索张拉和索力调节；并且各个横向张拉组件之间可形成统一有序但又富有变化的结构，系杆索的曲线平面线形与内倾的拱肋相呼应，形式新颖，造型美观。
