The invention provides an abutting apparatus for reinforcing steel bars. On the basis of guaranteeing the abutting quality of the reinforcing steel bars and not increasing labor force, the construction speed of a sleeve joint of the reinforcing steel bars can be improved. The abutting apparatus for the reinforcing steel bars comprises a sleeve clamping fixture and a sleeve rotating clamp, wherein the sleeve clamping fixture comprises a clamping tube, a clamping handle and a gear; the sleeve rotating clamp comprises a rotating handle and a retainer ring; a ratchet matched with the gear and a first elastic component are arranged at a hinged part of the retainer ring; the first elastic part drives the ratchet to have a tendency of rotating towards one direction by taking a hinge point as a pivot. According to the abutting apparatus for the reinforcing steel bars, disclosed by the invention, the sleeve clamping fixture is used for fastening a sleeve; the sleeve rotating clamp is used for enabling the sleeve clamping fixture and the sleeve to jointly rotate so as to realize the abutting of two thread reinforcing steel bars; the sleeve clamping fixture and the retainer ring of the sleeve rotating clamp are of two split structures, so that the opening or closing can be conveniently realized; the abutting apparatus is particularly suitable for abutting the thread reinforcing steel bars of a filling pile in a deep pile hole, and is beneficial for safe production and improvement on the working efficiency of abutting of the reinforcing steel bars.
