PURPOSE: To promote the axial field strength of a column by placing high strength concrete into a hollow section of a steel pipe winding precast concrete pile to form a column, and connecting a beam structural steel to an outside diamond ring provided to the peripheral surface of the steel pipe of a joint section of the column.
CONSTITUTION: High strength concrete 3 is placed into a hollow section of a precast concrete pile 4 (SC pile) to form a column 1. After that, beam structural steels 2 connected to an outside diamond ring 5 provided to the peripheral surface of a steel pipe of a joint section of the column 1. The axial yield strength of the column 1 is increased by enhancing quality, strength and compression yield strength of an inside concrete 4b of the precast concrete pile 4. Excellent mechanical performance is provided to the column 1 by introducing prestress to the inside concrete 4b. In addition, the axial yield strength higher than the same strength as that of a general steel pipe concrete column is provided to the column by the composite effect of the steel pipe 4a and the inside concrete 4b.
