External steel anchor pipe of novel cable-beam anchoring system for cable-stayed bridge and operation method thereof
The invention discloses an external steel anchor pipe of a novel cable-beam anchoring system for a cable-stayed bridge and an operation method thereof, and belongs to the technical field of bridge design. The external steel anchor pipe is composed of a bearing plate, a steel anchor pipe body, an anchoring web, an upper stabilizing plate, a lower stabilizing plate, a bridge deck supporting plate, stiffening plates and studs. The bearing plate is welded to the bottom end of the steel anchor pipe body; one end of the anchoring web is welded to the pipe wall of the steel anchor pipe body, and theother end of the anchoring web is welded to a main beam web, a main beam top plate and a main beam bottom plate; the upper stabilizing plate and the lower stabilizing plate are welded to the steel anchor pipe body, the anchoring web and the main beam web respectively; the stiffening plates are welded to the position, between the upper stabilizing plate and the lower stabilizing plate, of the anchoring web and the positions, corresponding to the upper stabilizing plate and the lower stabilizing plate, of the inner side of a main beam; and the bridge deck supporting plate is welded to the upperend of the steel anchor pipe body and connected with a bridge deck through the studs. The invention further provides the operation method of the external steel anchor pipe of the novel cable-beam anchoring system for the cable-stayed bridge. The external steel anchor pipe is applicable to cable-stayed bridges with any span, loads are transmitted between inhaul cables and the main beam in a shearing force manner, on-site secondary welding is not needed, and the construction quality is guaranteed.
本发明公开了一种斜拉桥新型索梁锚固系统外置式钢锚管及其操作方法，属于桥梁设计技术领域，由承压板、钢锚管、锚固腹板、上稳定板、下稳定板、桥面支撑板、加劲板及栓钉组成；承压板焊接在钢锚管底端，锚固腹板一端与钢锚管管壁焊接，另一端与主梁腹板及顶、底板焊接，上、下稳定板分别与钢锚管、锚固腹板及主梁腹板焊接，上下稳定板之间的锚固腹板上和主梁内侧对应上、下稳定板的位置焊接加劲板，桥面支撑板焊接在锚管上端，与桥面板之间通过栓钉连接。本发明还提供了一种斜拉桥新型索梁锚固系统外置式钢锚管的操作方法。本发明可适用于任何跨径的斜拉桥，拉索和主梁之间通过剪力的方式传递荷载，无需在现场进行二次焊接，保证施工质量。
