Integral steel anchor beam of cable-stayed bridge and construction method of anchor beam
The invention particularly relates to an integral type steel anchor beam of a cable-stayed bridge. The integral type steel anchor beam is characterized in that a steel anchor beam system is composed of a steel anchor beam, a supporting structure, a limiting structure and a detachable and reusable temporary support. The steel anchor beam adopts an anchoring structure with a double-I-beam section and anchoring stay cables arranged at the two ends, and is manufactured and formed at a time in an all-welded mode. The supporting structure comprises a supporting bracket, a supporting padstone, an upper supporting steel base plate, a lower supporting steel base plate and a polytetrafluoroethylene plate and is used for supporting the steel anchor beam and transmitting the vertical component force of a stay cable to the main tower. The limiting structure comprises a transverse limiting block and a longitudinal limiting block and is used for restraining horizontal displacement of the steel anchorbeam under unbalanced cable force. The temporary support is of a truss structure composed of vertical web members, inclined web members, gusset plates and other components and used for supporting andpositioning the steel anchor beam in the construction period. The integral steel anchor beam of the cable-stayed bridge is manufactured and formed at a time, and the integrity of the structure is improved.
本发明具体涉及一种斜拉桥整体式钢锚梁，其特征在于所述的钢锚梁系统由钢锚梁、支撑结构、限位结构以及一种可拆卸、重复使用的临时支架组成。钢锚梁采用双工字梁截面，两端设置锚固斜拉索的锚固结构，采用全焊接方式一次性制作成型。支撑结构包括支撑牛腿、支撑垫石、上下支撑钢垫板和四氟板，用于支撑钢锚梁，并将斜拉索的竖向分力传递给主塔。限位结构包括横向限位块和纵向限位块，用于约束钢锚梁在不平衡索力下产生的水平位移。临时支架为由竖腹杆、斜腹杆和节点板等构件组成的桁架结构，施工期间用于支撑及定位钢锚梁。本发明一种斜拉桥整体式钢锚梁采用一次性制作成型，提高了结构的整体性。
