PROBLEM TO BE SOLVED: To provide a joint structure which enables jointing to be surely performed even if an insertion opening for reinforcements is opened above a sleeve joint. SOLUTION: The reinforcement 42 is inserted into the reinforcement insertion opening 24 of the sleeve joint 23 from above; grout is injected from a grout injection port 35, so as to be poured from the insertion opening 24; and vibrations are applied to the grout. Preferably, when the vibrations are applied to the grout, a small-diameter vibrator 54 is inserted into the grout injection port which is provided in the side surface of the sleeve joint 23, and the vibrations are applied to the grout in the sleeve joint 23 by the vibratos 54.
