PROBLEM TO BE SOLVED: To provide a tool for filling a joint to serve for application to reliably close a gap, provided after a pipe is installed at an opening for an equipment piping, simply with the reduced number of components. SOLUTION: A tool for filling a joint is formed such that by forming protrusion and recessed parts 2 and 4 for fit-in on and in two-division cylindrical bodies 1 with a flange formed of foamed resin, such as foamed polystyrene, the division cylindrical bodies 1 are joined together without using a different part and concrete is easily poured in a gap relative to a slab adhered to a pipe.
