The connection method between the I-beam 19 and the main beam 3 is the same as the connection method between the I-beam 19 and the main beam 1.

[0036] Hook 11 is also provided on the platform plate 23. The hook 11 is semi-circular, and four hooks 11 are arranged in a rectangle. After the four hooks 11 pass through the platform plate 23, they are respectively welded above the secondary beam 1 5 and above the secondary beam 2 6. An operation frame 24 and a construction formwork 16 are erected above the operation platform, and specific construction operations are carried out on the construction formwork 16. When the operation height needs to be adjusted, a hook rope is used to connect the hook 11 on the platform plate 23, and then a crane or tower crane is used to lift the platform to a height slightly higher than the reserved hole 14. After inserting the support member 12 into the reserved hole 14, the operation platform is placed on the support member 12, and then the operation platform and the support member 12 are fixed using the connecting member 17.
