The invention belongs to the technical field of arch bridge design and construction, and particularly relates to a beam-arch combined bridge suspender beam end anchoring structure and a construction method. The anchoring structure at least comprises a longitudinal beam and further comprises a suspender kit. The bottom end of the suspender kit is connected with a beam end anchoring assembly; the top end of the beam end anchoring assembly is arranged on the upper portion of the longitudinal beam, and the lower middle portion of the beam end anchoring assembly is vertically fixed in the longitudinal beam. The suspender beam section anchoring structure is simple in structure, clear in stress, good in anchoring performance and high in reliability. The construction method is simple, an operation platform does not need to be installed at the beam bottom, grouting pipes do not need to be pre-buried, grouting and other operations do not need to be carried out, cement paste equal strength time is saved, procedure connection is accelerated, and therefore suspender installation and tensioning operation can be carried out in time.
本发明属于拱桥设计与施工技术领域，具体涉及一种梁拱组合桥吊杆梁端锚固结构及施工方法。本发明的锚固结构至少包括纵梁，还包括吊杆套件；吊杆套件的底端连接有梁端锚固组件；梁端锚固组件的顶端置于纵梁的上部，梁端锚固组件的中下部竖直的固定在纵梁内部。本发明提供的吊杆梁段锚固构造结构简洁，受力明确，锚固性能好，可靠度高。本发明所采用的施工方法简单，无需在梁底安装操作平台，无需预埋注浆管及进行注浆等操作，省去了水泥浆等强时间，加快了工序的衔接，从而能够及时的进行吊杆安装、张拉作业。
