Description

Technical Field

[0001] The utility model relates to the technical field of bridge construction, in particular to a transverse tensioning operation platform device for a railway T-beam bridge. Background Art

[0002] T-beam bridge is a beam bridge with T-beam as the main load-bearing structure. When the load on the bridge generates positive bending moment, the beam is made into a T-shape with a large top and a small bottom and reinforced at the lower edge to fully utilize the high compressive strength of concrete and the high tensile strength of steel bars, thereby saving materials and reducing deadweight compared to rectangular beam bridges. However, it is not suitable for situations where loads will generate large negative bending moments, and its torsional stiffness stability is lower than that of box beam bridges.

[0003] When the existing T-beam bridge is about to be completed, it is necessary to construct the horizontally reserved tensioning holes to ensure the horizontal connectivity of the beam body. Since T-beam bridges are usually high, there are many reserved tensioning holes, and tensioning holes are designed on both the upper and lower sides. At present, workers are mostly lifted and lowered by hanging ropes or lifting platforms to tension the outer side of the T-beam bridge. The operating platform used is not convenient to move along the bridge during use, and has poor stability. It is easy to shake significantly during construction, posing a major safety hazard.
