Suspender anchoring device for small and medium span steel structure arch bridge
The invention relates to the field of arch bridges, and discloses a small and medium span steel structure arch bridge suspender anchoring device which comprises a screw arranged at the end of a suspender, a tensioning structure arranged on the screw and a fixing component fixedly arranged relative to a base. A lug plate is fixedly arranged on the upper surface of the base, the fixing part comprises an anchor plate sleeving the outer side of the screw, the lower surface of the anchor plate is fixedly connected with one end of a steel plate, and the other end of the steel plate is detachably connected with the lug plate; the tensioning structure comprises a center hole jack arranged on the screw rod, a tensioning platform used for bearing counter force generated during tensioning of the center hole jack is arranged between the anchor plate and the center hole jack, the screw rod is in threaded connection with a first nut, and when tensioning of the center hole jack is completed, the first nut abuts against the anchor plate, so that anchoring is completed. The cross-core jack is arranged on the screw rod at the end part of the suspender, so that the tensioning force of the jack directly acts on the suspender, the suspender can be conveniently tensioned, and the elongation of the suspender can be randomly adjusted.
本发明涉及拱桥领域，公开了一种中小跨径钢结构拱桥吊杆锚固装置，包括设置在吊杆端部的螺杆，设置在螺杆上张拉结构，以及相对底座固定设置的固定部件；底座上表面固定设置耳板，固定部件包括套设在螺杆外侧的锚板，锚板下表面与钢板一端固定连接，钢板另一端与耳板可拆卸连接；张拉结构包括设置在螺杆上的穿心千斤顶，锚板与穿心千斤顶之间设置有用以承受穿心千斤顶张拉时产生的反力的张拉平台，螺杆螺纹连接有第一螺母，当穿心千斤顶张拉完成，第一螺母与锚板相抵，从而完成锚固。本发明通过在吊杆端部螺杆上设置穿心千斤顶，使千斤顶的张拉力直接作用于吊杆上，较为方便地实现对吊杆的张拉，而且能够任意调节吊杆伸长量。
