[0018] In the prior art, when steel structures are applied to buildings, the steel structures are connected together using a variety of steel structure splicing methods such as straight-line splicing, cross splicing, and T-shaped splicing. The strong hardness of the steel structure leads to strong conductivity of the steel structure, and most of the steel structures are spliced together by bolts during the splicing process. This causes the vibration force to be transmitted to the bolts when the building steel structure is vibrated, which can easily cause the bolts to fall off from the threaded holes due to vibration. The falling of the bolts will cause the steel structure connection to be unstable, and if the bolts are not maintained in time, the building steel structure will collapse or be damaged, which poses a great safety hazard to the building steel structure.

During the construction process, concrete can be added into the pouring hole 107 and between the two matching plug plates 202. The concrete can strengthen the connectivity and integrity between the building steel column 101 and the building steel beam 201.
