PURPOSE: An apparatus for fixing the position of a riser pipe is provided to stably couple a riser pipe to a connection hole of a slab at an initial position by fastening a nut of a space regulator. CONSTITUTION: An apparatus for fixing the position of a riser pipe comprises a body, a fastening unit, and a space regulator(G). The fastening unit is coupled to the body and fixes a riser pipe(P). The space regulator fixes the riser pipe to the connection hole(H) of a slab. The space regulator is composed of an inclined groove(180), a screw hole(184), a fixing plate, a fastening piece(600), and a nut(620). The inclined groove is formed on the bottom surface of a contact part(102) of the body. The screw hole vertically penetrates through the inclined groove. The fixing plate is inserted into the inclined groove and has multiple wedges(742). When the fastening piece and the nut are fastened, the wedges are supported by the inner wall of the connection hole.
