The end plates are vertically provided with second ear plates. The second ear plates at the upper and lower ends of the steel assembly column 2 are respectively connected to the first ear plates 111 of the clamping structure 1 on the upper and lower adjacent floor slabs 5.

[0030] The first column hoop 3 includes two side plates 31 and a tie assembly 32. The two side plates 31 are pressed against opposite sides of the two flange plates 21. The tie assembly 32 is tied between opposite sides of the side plates 31. The opposite sides of the two side plates 31 are respectively provided with third ear plates.

[0031] As a preferred embodiment, two opposite sides of the side plate 31 extend to the outside of the side portion of the flange plate 21. The length of the side plate is greater than the outer diameter of the steel assembly column.
