Description

Technical Field

[0002] During the construction of elevated ramps, it is often necessary to use supporting equipment to support and fix the box girders required for the elevated ramps. The utility model patent with patent application number CN201922129049.8 discloses an anti-overturning support structure for the box girder. The positioning rod is pulled hard to make the magnet block leave the support seat, and the inner spline sleeve moves along the outer spline of the support shaft, thereby releasing the positioning of the inner support rod. Then, the inner support rod is rotated by the cooperation of the positioning rod and the spline, so that the inner support rod can adjust its angle to adapt to different box girders. After the adjustment is completed, the positioning rod is moved by the magnet block. The rod is adsorbed and fixed on the support seat, thereby positioning the position of the inner support rod; then the height of the outer support rod on the inner support rod is adjusted according to the height of the box girder side beam to adapt to box girders of different heights. According to the technical scheme disclosed by the invention, when the existing bridge box girder support equipment is used, on the one hand, it is unable to adjust the support height of the bridge box girder according to the height of the elevated ramp, and on-site casting is often required, which reduces the construction efficiency; on the other hand, when the bridge box girder is reinforced, it is easy to lose the reinforcement effect due to the deflection between the bridge box girder and the support mechanism, which is not conducive to ensuring the support firmness of the bridge box girder.
