Weight system of large-span superposed beam cable-stayed bridge
The invention provides a weight system of a large-span superposed beam cable-stayed bridge, which mainly solves the problems in the prior art that in the construction process of the large-span superposed beam cable-stayed bridge, saddle weights are of a large size and not easily placed, the applied weight cannot be accurately controlled, and the saddle weights are easily shifted due to long-time stacking. The weight system of the large-span superposed beam cable-stayed bridge comprises a small longitudinal beam of a weight area used for supporting a weight plate, weight boards used for placing the saddle weight and concrete prefabricated saddle weights; the lower end of the small longitudinal beam is connected with a main body of the bridge; the adjacent weight boards are separated by skid-resistant felts; shoulder flanges are arranged at the peripheries of the weight boards; the shoulder flanges are provided with reserved lifting rings used for lifting and reserved anchor holes which are in bolted connection with an upper end face of the small longitudinal beam of the weight area. The saddle weights comprise a first saddle weight, a second saddle weight and a third saddle weight, which are orderly arranged from top to bottom; every two adjacent saddle weights are clamped and fixed through matched bulges and clamping slots; skid-resistant felts are arranged between the saddle weights and the shoulder flanges. The weight system of the large-span superposed beam cable-stayed bridge, disclosed by the invention, has the advantages of simple structure, convenient construction and high reliability.
