PURPOSE: A supporter for a riser pipe is provided to generate elastic force when a riser pipe is coupled to the connection hole of a slab by successively inserting first and second split bodies into a gap between the riser pipe and the connection hole. CONSTITUTION: A supporter for a riser pipe comprises a pair of bodies. The body comprises first and second split bodies(120,120a), elastic blades(200), a pair of female grooves(300), and a pair of male protrusions(400). The first and second split bodies cover a riser pipe(P) at a connection hole(H). The elastic blades are elastically supported by the inner wall of the connection hole. The female grooves and the male protrusions are formed on the surfaces of the first and second split bodies, respectively. The body supports the riser pipe by vertically coupling the female grooves and the male protrusions in a circular shape.
