Example Embodiment
[0023] The assembly steps of the above-mentioned circular steel tube concrete column are as follows:
[0024] 1. All components are prefabricated in the factory except for grouting the reserved holes of the semi-circular steel plate at the column-to-column connection part. The size and spacing of the bolt holes reserved on the column flange connector 3 should meet the Construction requirements. The embedded steel sleeves 10 in the upper and lower circular steel tubular columns 1 and 2 should correspond to and match with the bolt holes 6 reserved on the column flange connector 3 ( image 3 and Figure 4 shown);
[0025] 2. Place the column flange connector 3 on the side where the steel sleeve 10 is reserved for the lower circular concrete-filled steel tubular column 2, so that the bolt holes 6 reserved on the column flange connector 3 are aligned with the holes of the steel sleeve 10, and install 6. For bolt rods 8 and gaskets 9, complete the splicing of the lower circular C...
