[0002] Exposed column bases are widely used as connecting components between steel columns and foundations because of their convenient manufacturing and simple structure, especially between industrial and civil buildings and foundations below 50m in height. At present, most exposed column bases are equipped with components such as a compression column base plate, a vertical shear plate, and anchor bolts, and a shear cup is set on the top of the foundation. The shear force is borne by inserting the column base shear key into the shear cup. However, the exposed column base has the following shortcomings during use: (1) The processing error increases due to the long column base, and adjustment is difficult; (2) The secondary grouting layer is thin (generally 50mm-100mm), resulting in poor integrity of the bond with the foundation, easy to fall off and crack; (3) The cup mouth of the shear cup on the foundation is cumbersome to construct and difficult to ensure quality; (4) When the column base shear key is inserted into the shear cup, the cup mouth is required to have a high processing accuracy; (5) It is difficult to pour concrete around the cup mouth of the shear cup. Therefore, it is necessary to improve the existing technology. Summary of the invention
