PROBLEM TO BE SOLVED: To provide an anchor installation construction method for a steel framed reinforced concrete building which is simple in a construction method, and excellent in the shear rigidity or shear durability and tensile rigidity or tensile durability of an anchor bar.SOLUTION: An insertion hole 20 is formed for inserting an anchor bar 18 by performing core cutting of skeleton concrete 16 of an anchor installation site in a steel framed reinforced concrete building to the surface of a steel frame 12, and the anchor bar 18 is welded to the surface of the steel frame 12 in the insertion hole 20, and a pipe-mounted plate 22 mounted with a packing material injection pipe 36 and an exhaust pipe 38 is inserted to a predetermined depth in the insertion hole 20, and a gap between the opening end of the insertion hole 20 and the pipe-mounted plate 22 is filled with clay-like packing materials to form a seal section 40, and liquid packing materials 44 are injected via the packing material injection pipe 36 into a void portion 42 in the deep part of the seal section 40 in the insertion hole 20 to fill the void portion 42. |
