PROBLEM TO BE SOLVED: To provide a jointing structure and a jointing method effective for the jointing of a full precast floor slab to a steel-frame beam. SOLUTION: A stud dowel 8, which is welded to a top surface of the steel-frame beam 2, is arranged in a steel pipe 5 which is embedded in the full precast floor slab 1, and shrinkage-compensating mortar 9 is infilled into the steel pipe in a restricted state, so that the steel pipe and the stud dowel can be integrated together by shrinkage-compensating mortar and so that the shrinkage-compensating mortar can function as a stress transfer member between the steel pipe and the stud dowel. A U-shaped joint bar 7 is arranged in the full precast floor slab, and a leading-end bent part 7a is wound around the outside of the steel pipe. A protrusion 3 as a shear cotter and a recess 4 are alternately formed at the edge of the full precast floor slab so that the steel pipe can be embedded in the protrusion; the shear cotters of both the full precast floor slabs, which are laid on both the upper sides of the steel-frame beam, are meshed with each other; and post-cast concrete 10 is infilled between the shear cotters.
