The present invention provides a steel bar spacing material for nailing which is capable of injecting grout. The steel bar spacing material of the present invention is provided to maintain intervals among multiple reinforcing steel bars arranged inside a bored hole, and comprises: a steel bar supporting unit which has multiple steel bar fixating grooves formed at constant intervals in the circumferential direction of the outside of a body corresponding to the reinforcing steel bars and which has the reinforcing bars inserted and fixated in the steel bar fixating grooves thereof; and a grout injection unit which is provided with an injection guide hole formed by penetrating the body of the steel bar supporting unit to be parallel to the steel bar fixating groove and with multiple discharge holes penetrating the outer surface of the body of the steel bar supporting unit corresponding to the gap between the steel bar fixating grooves contiguous with each other to be communicated with the injection guide holes and which injects grout to be filled inside the bored holes by discharging the grout, which is injected through the injection guide hole, through the discharge hole into the bored hole. |
