[0017] The utility model is further described below in conjunction with the accompanying drawings and embodiments:

[0018] like Figure 1-Figure 4 As shown, a movable Bailey structure steel platform comprises a steel platform 1 and two cast-in-place lower cross beams 2, wherein the cast-in-place lower cross beams 2 are symmetrically arranged, and a plurality of steel platforms 1 are arranged between the cast-in-place lower cross beams 2;

[0019] Among them, the steel platform 1 includes a steel platform body 11, a lower main beam 12, a distribution beam 13 and a patterned plate 14. A lower main beam 12 is fixedly installed on both sides of the bottom surface of the steel platform body 11. A plurality of distribution beams 13 are evenly distributed on the top surface of the steel platform body 11. Each of the distribution beams 13 is fixedly installed on the top surface of the steel platform body 11. The patterned plate 14 is fixedly installed on a plurality of the distribution beams 13. The lower main beam 12 is abutted against the cast-in-place lower cross beam 2.
