Description

Technical Field

[0001] The utility model relates to the technical field of prefabricated steel structure construction, in particular to a column ear plate clamping device and a column docking system. Background Art

[0002] The splicing of steel columns is an important link in steel structure construction. During the splicing construction process of steel columns, ear plates are usually arranged on both sides of the steel columns to align the upper and lower column bodies. As Figure 1 shown, the existing method is generally to open through holes in the ear plates, and then fix connecting plates on both sides of the ear plates with multiple bolts. After fixing the positions of the upper and lower columns, welding is carried out.

[0003] In order to ensure the stability and accuracy of the ear plate connection, multiple bolts are generally required for fixation. Due to the large number of bolts, it takes a long time to fix the ear plates, and the construction efficiency is low; at the same time, the long construction time is likely to cause the displacement of the columns, affecting the construction effect.
