Abstract:
PURPOSE: To obtain a small diameter reinforced pole and to enhance the workability by dividing a core into a plurality of segments which are inserted in a steel pipe, and by welding and fixing the core to the inner surface of the steel pipe.
CONSTITUTION: A first core 2 is inserted into a steel pipe 1 and is welded and fixed to a part of the inner surface of the steel pipe 1. Then, another core 2 is inserted into the steel pipe 2, and then a limiting stopper 3 is fitted on one end part 3' of the first core 2.
