Device and method suitable for accurately positioning arch foot steel pull rod of steel truss arch bridge
The invention relates to a device and method suitable for accurately positioning steel tie rods of arch feet of a steel truss arch bridge, the device comprises first positioning steel plates and second positioning steel plates, the length of the steel tie rods in a concrete skewback foundation is L, the L is divided into n sections, the first positioning steel plates are arranged at starting nodes, and the second positioning steel plates are arranged at middle nodes; a plurality of through holes are formed in the first positioning steel plate and the second positioning steel plate, steel pull rods penetrate through the through holes, and the positions of the first positioning steel plate and the second positioning steel plate are fixed through quadrangular coordinates. Steel frame structures are arranged between the first positioning steel plates and the second positioning steel plates, between the adjacent second positioning steel plates and between the second positioning steel plates and the lower bearing plate. The steel frame structures are connected with the first positioning steel plates and the second positioning steel plates in a welded mode. The steel pull rod can be limited, the steel pull rod is prevented from deflection due to the dead weight or deformation due to impact of concrete pouring, and it is ensured that the long steel pull rod keeps vertical construction with the upper bearing plate and the lower bearing plate.
本发明关于一种适用于钢桁架拱桥拱脚钢拉杆精准定位的装置及方法，该装置包括第一定位钢板和第二定位钢板，混凝土拱座基础中钢拉杆的长度为L，L划分为n段，起点节点处设置第一定位钢板，中间节点处均设置第二定位钢板，终点节点处用于设置下承压板，第一定位钢板和第二定位钢板上设有若干个通孔，通孔用于钢拉杆穿过，通过四角坐标固定第一定位钢板和第二定位钢板的位置，第一定位钢板和第二定位钢板、相邻第二定位钢板、第二定位钢板和下承压板位置之间均设有钢架结构，钢架结构与第一定位钢板和第二定位钢板焊接连接。本发明能够对钢拉杆进行限位，避免钢拉杆自重下挠或受混凝土浇筑冲击形变，确保较长的钢拉杆与上、下承压板保持垂直施工。
