STRUCTURE FOR DURABLE PRESTRESSING STEEL FIXING PART

摘要

PROBLEM TO BE SOLVED: To provide a structure for a durable prestressing steel fixing part by using a bearing plate with low manufacturing cost and easy installation work. SOLUTION: The bearing plate 1 provided with a plurality of insertion holes 2 for single strand type tendons 3 and formed with anticorrosion coating 1a by rustproofing is used in the fixing part of prestressed concrete. In a back face of the bearing plate 1, one set of grid like reinforcing steel 4 comprised by respectively bending one piece of longitudinal reinforcing steel and one piece of lateral reinforcing steel is arranged in the prestressed concrete. One with one prestressing steel stranded wire inserted in one sheath 11 and filled in between with cement grout 12, or one with one prestressing steel stranded wire inserted in one synthetic resin sheath 11 and filled in between with delayed curing type resin grout 12 can be given as examples of the single strand type tendons 3.
