According to the present invention, even if the on-site joining joints of large steel blocks are welded, the joining work can be done in the factory, and the centering and joining of the steel blocks can be done during on-site installation work. Since the dimensions can be easily secured, it is effective in improving the efficiency of on-site work and improving the accuracy of on-site welding groove dimensions. Also, since the two blocks are temporarily connected using bolts and knock pins using a reinforcing diaphragm,
It can also be used as a reinforcing diaphragm and can be constructed at low cost.
