[0010] Preferably, a bottom support plate is fixedly installed at the bottom of the steel beam column, and the bottoms of the inner support steel bars and the side support blocks are fixedly connected to the top of the bottom support plate.

[0011] Compared with the prior art, the advantages and positive effects of the utility model are:
