[0003] When existing connection devices are used for assembly between concrete columns, high-strength bolts and steel plates are usually used to connect the columns. However, this connection method often requires the concrete columns to be accurately installed into prefabricated holes for assembly, which is very time-consuming and labor-intensive. In addition, the single bolt installation structure often makes it difficult to firmly splice and assemble the concrete columns, which in turn affects the safety and stability of the device when used.
