[0002] Compared with traditional cast-in-place, steel structures have advantages such as shortening construction period and reducing construction waste. With the increase of assembly rate, more and more steel structures are being used. Steel structure construction is to transport the steel beams and columns produced in the factory to the construction site for splicing. In the prior art, ear plates are usually welded on steel columns, and the splicing of the steel columns is completed by connecting the ear plates of the upper and lower steel columns. After the splicing is completed, the ear plates are cut off. This method leaves residual weld feet on the steel columns, affecting the splicing of the steel columns with other components, resulting in low splicing efficiency of the overall structure. For this reason, we provide a detachable steel structure splicing ear plate. Utility Model Content
