Summary:PROBLEM TO BE SOLVED: To provide a precast pre-stressed concrete beam making on-site assembly/installation work easy and capable of shortening a construction period.SOLUTION: A precast pre-stressed concrete beam 10 stretched over between a pair of columns 2 is configured by two end pieces 11 divided in the axial direction and respectively arranged at axial ends and a center piece 12 arranged in an axial center. The end piece 11 has: a joint section 2a of the column which is integrally formed at one end of the end piece; main reinforcements 25 extending in the axial direction; and pretension tendons 27 arranged in an upper flange part 21. The center piece 12 has: main reinforcements 35 extending in the axial direction; and pretension tendons 37 arranged in a lower protrusion part 32. The end piece 11 and the center piece 12 are directly joined with each other by joining the main reinforcements 25 and the main reinforcements 35 together by reinforcement joints 40. Thus, the necessity for on-site concrete placing of junctions 13 is eliminated.
