[0033] Example 1: Reference Figure 3 and Figure 4 The welding base 7 is concave, and the welding base 7 is inverted on the fixed steel structure (ie, the fixed steel structure 1), and the two sides of the concave shape are fixedly connected to the fixed steel structure 1, and the fixing at this position can be welding.

[0034] Example 2: Reference Figure 5 and Figure 6 As shown, the connection between the disassembly base 6 and the welding base 7 is bolted. Specifically, six threaded holes 71 are provided on the upper part of the welding base 7, and six countersunk holes 61 are provided at positions corresponding to the six threaded holes on the disassembly base 6.
