Method for mounting reinforcing steel bars of tower columns of cable-stayed bridge towers
The invention discloses a method for mounting reinforcing steel bars of tower columns of cable-stayed bridge towers. The method comprises the following steps: (1) arranging a tower crane on one side of a foundation platform of each tower along the axis of a bridge deck, and arranging two assembly jig frames, close to the corresponding tower crane, of each of two sides of the axis of the bridge deck; (2) pre-assembling reinforcing steel bar sections of the tower columns one by one in each assembling jig frame; (3) hoisting the first assembled reinforcing steel bar section as a first reinforcing steel bar section to the top end of the foundation platform of each tower and carrying out aligned connection, and then taking the reinforcing steel bar section as a frame to cast concrete; (4) aligning and connecting a next reinforcing steel bar section to the top end of the reinforcing steel bar section on which the concrete is cast, and taking the newly connected reinforcing steel bar section as a frame to cast concrete; (5) repeating the step (2) and the step (4) till finishing the mounting of the tower columns. According to the method disclosed by the invention, the construction efficiency of tower mounting is effectively improved, the construction quality is also effectively improved, and meanwhile, the construction safety is ensured.
