Abstract

PURPOSE: To maintain the root spacing uniform and exact by providing plural openings along the part of largest diameter of the body, and installing a freely sliding chill strip at the upper end of lower cylindrical body and inner circumference of the lower end of upper cylindrical body to be welded, and providing a holding piece to maintain the root spacing uniform and exact.
CONSTITUTION: In the case where the lower cylindrical body 1 is a lower pile and the upper cylindrical body 2 is an upper pile, a chill strip 3 of the size that fits to the outer circumference of the part of largest diameter is inserted in the inner circumference of the upper end of the lower pile driven first allowing free sliding. Next, a root spacing maintaining piece 5 is inserted from the wedge-shaped tip making its tip project from the outer circumference of the chill strip 3, and the tip of projecing maitaining piece 5 is placed on the top of the lower pile. When the lower end of the upper pile is placed on the tip of the maintaining piece 5, specified root spacing is maintained between the top of the lower pile and the lower end of the upper pile. Thus upper pile and lower pile are welded under this condition.
