PROBLEM TO BE SOLVED: To provide a projection structure of an anchorage or a deviator of a tendon and its construction method for forming a work scaffold for the work for installing an anchor, reinforcing bars, a form or the like into a concrete surface, improving working efficiency and safety of the work, preventing the form in an anchorage, or the like, from assuming a floating form, reducing the time and labor required for assembly of the form, removing assembly of a projection being a critical path in a cycle process for constructing a beam by blocks out of the cycle process for shortening the time required by the cycle process, when constructing the anchorage and the deviator of the tendon of a PC structure. SOLUTION: When an anchoring projection part 2 of a PC steel product is constructed at a predetermined position of a lower floor slab 1 of a PC box girder bridge, a lower part of a hole drilled steel plate dowel 10 as a concrete dubel for integration is buried, when constructing the lower floor slab 1, and the anchoring projection part 2 is constructed separately, after the construction of the lower floor slab 1 and is integrated with the lower floor slab 1 via a connecting member 10.
