Positioning support of suspension bridge prestress anchoring system and construction method
The invention relates to the field of suspension bridge anchoring system construction, in particular to a positioning support of a suspension bridge anchorage prestress anchoring system and a construction method. The positioning support comprises a first base frame and a lower-layer support connected with the first base frame, and the first base frame is connected with the first-layer concrete of an anchor block through an embedded steel plate. The positioning support also comprises a second base frame and an upper-layer support connected with the second base frame, and the second base frame is connected with the first-layer concrete of the anchor block through an embedded steel plate. Frameworks of the first base frame, the second base frame, the lower-layer support and the upper-layer support are each composed of a vertical rod, a horizontal connector and an inclined strut, and the horizontal connectors and the inclined struts are connected with the vertical rods through gusset plates in a welded mode. The upper-layer support and the lower-layer support further comprise positioning cross rods, arc plates are arranged on the positioning cross rods, and the arc plates are used for positioning a prestressed pipeline. The construction method is used for installing the positioning support. Additional stress generated by positioning deviation can be reduced to the maximum extent, and system safety is ensured.
本发明涉及悬索桥锚固系统施工领域，特别是涉及一种悬索桥锚碇预应力锚固系统的定位支架及施工方法。所述定位支架包括：第一基架和与之连接的下层支架，所述第一基架与锚块第一层混凝土通过预埋钢板连接；第二基架和与之连接的上层支架，所述第二基架与锚块第一层混凝土通过预埋钢板连接；所述第一基架、第二基架、下层支架和上层支架的骨架均由竖杆、平联和斜撑组成，所述平联和斜撑通过节点板与竖杆焊接连接；所述上层支架和下层支架还包括定位横杆，在所述定位横杆上设有圆弧板，所述圆弧板用于对预应力管道进行定位。所述施工方法用于安装上述定位支架。本发明能够最大限度降低定位偏差产生的附加应力,确保系统安全。
