Horizontal steel pins 5 are provided on the side walls of the lower column 1 and the upper column 2. The two horizontal steel pins 5 pass through the side walls of the lower column 1 and the upper column 2 respectively, and the two horizontal steel pins 5 pass through the side walls of the butt joint 3. Two longitudinal steel pins 6 distributed longitudinally are provided between the two horizontal steel pins 5. The two longitudinal steel pins 6 pass through the side walls of the lower column 1 and the upper column 2 respectively, and the two longitudinal steel pins 6 also pass through the side walls of the butt joint 3. The two horizontal steel pins 5 and the longitudinal steel pins 6 pass through the lower column 1 and the upper column 2 in a cross shape and pass through the side walls of the butt joint 3 at the same time, so that the upper and lower ends of the butt joint 3 are tightly connected to the upper column 2 and the lower column 1 respectively, ensuring the connection stability of the lower column 1 and the upper column 2.
