Description

[0002] Background of the demand for bridge construction development With the continuous development of transportation infrastructure, the construction of large-span bridges is increasing. In the construction of prestressed concrete continuous rigid frame bridges, continuous beam bridges and other bridge types, the cross-sectional form of the beam body often changes according to factors such as the stress characteristics. Traditional hanging baskets have limitations when facing the construction of variable-width cross-section beams. In traditional hanging basket construction, the hanging basket can only move in a straight line. It is suitable for the casting of box beams with constant cross-sections, but not for the casting of box beams with variable cross-sections. The position and shape of the hanging basket need to be adjusted frequently to adapt to the construction of variable cross-sections. The hanging basket needs to withstand various loads during the construction process. The deformation is small after being subjected to force. At the same time, the weight of the hanging basket itself is reduced, which facilitates the movement and adjustment of the hanging basket.
