The lining plate embedded in the PC plate for welding welds the die steel materials arranged on the opposing surfaces of the PC plate along the welding line where mutual interference of the on-site welding line is avoided, thereby improving workability. Is improved, the construction of the PC plate and the workability of the on-site weld are improved, and the rigidity of the PC plate is high, so the quality of the on-site joint can be improved.
