The invention discloses a stay cable and concrete bridge tower anchoring structure with embedded steel plates, which comprises two arc-shaped steel plates. The arc-shaped steel plates are pre-buried in the concrete bridge tower; at least one end of the arc-shaped steel plate extends out of the concrete bridge tower; the extending ends of the two arc-shaped steel plates correspond to each other, two connecting steel plates are arranged between the ends of the arc-shaped steel plates, the arc-shaped steel plates and the connecting steel plates define a box-shaped structure, the ends, located onthe side of the concrete bridge tower, of the connecting steel plates are connected with anchor bearing plates, and the anchor bearing plates are used for anchoring stay cables. The anchoring structure is hoisted to be arranged on the concrete bridge tower and connected with the concrete bridge tower in a cast-in-place mode. The space for internal welding does not need to be reserved, the transverse size of the anchoring structure can be reduced, the steel consumption of the anchoring structure is reduced, the transverse size of the concrete bridge tower is greatly reduced, and the appearanceof the concrete bridge tower is lighter and more attractive.

本发明公开了一种预埋式钢板的斜拉索和混凝土桥塔锚固构造，包括两块弧形钢板，所述弧形钢板预埋在混凝土桥塔内，所述弧形钢板的至少一端伸出所述混凝土桥塔外，两块所述弧形钢板的伸出端对应，且所述弧形钢板端部之间设有两块连接钢板，所述弧形钢板和所述连接钢板围成箱型结构，所述连接钢板位于所述混凝土桥塔侧的一端连接有锚垫板，所述锚垫板用于锚固斜拉索。通过吊装所述锚固构造设置于所述混凝土桥塔上并现浇连接，无需预留进入内部施焊的空间，可将所述锚固构造自身横向尺寸减小，节省所述锚固构造自身的用钢量，大大减小所述混凝土桥塔横桥向尺寸，使所述混凝土桥塔外形更加轻盈美观。
