Technical Field

The present application relates to the field of box girder tensioning, and in particular to an energy-saving box girder tensioning auxiliary operation platform.

Background Art

A box girder is a type of beam used in bridge engineering. It is hollow inside and has flanges on both sides of the upper part. Prestressing of a box girder is to add tension to the box girder component in advance, so that the prestressed box girder component is subjected to compressive stress, thereby causing it to undergo a certain deformation to cope with the loads borne by the box girder structure itself, including the load of the box girder component's own weight, wind load, snow load, earthquake load, etc. Generally, steel strands, jacks, anchor plates, and clips are used for prestressing.

During the prestressing construction of box girders, a cylinder device is required. As the box girders are installed section by section, the jacks need to be hoisted and the hydraulic drive device moved multiple times, which is inconvenient. Therefore, it is necessary to design an energy-saving box girder tensioning auxiliary work platform to facilitate the movement of tensioning construction tools.
