Abstract

To provide a connecting pole for connecting upper and lower poles, to enhance the strength of the connecting part, to provide shear reinforcement of the lower pole, and to prevent concrete from dropping out even when the concrete part is subjected to shear failure.SOLUTION: An upper pole 10 forms an upper connection part 7 provided with an upper connection steel pipe 8 continuous to the lower end of an outer peripheral reinforcing steel pipe 6 of the upper pole body 10a (Figure a). A lower pole 30 forms a lower connection part 27 provided with a lower connection steel pipe 28 below an upper-end plate 21 of a lower pole body 30a (a). A connection pole 40 is constituted by bringing the connection part 7 side of the upper pole 10 close to the upper part of the lower pole 30 and bringing the inner surface of the upper connection steel pipe 8 of the upper pole 10 into close contact with the outer surface of the lower connection steel pipe 28 of the lower pole 30 (b). An overlapping margin in which the lower connection steel pipe 28 and the upper connection steel pipe 8 adhere is made to be long enough in comparison with the outer diameter, and a clearance 33 is formed between the lower end plate 2 of the upper pole 10 and an upper end 31 of the upper pole.SELECTED DRAWING: Figure 1
