The invention discloses a grouted deformed steel tube sleeve abutted and connected by a steel bar grouting anchor. Two connected steel bars (7) are oppositely inserted from two ends in a seamless steel tube (1), and a high-strength shrinkage-free cement-based grouting material (8) is filled in a cavity, so that a steel bar abutted grouting anchor connector is formed; the grouted deformed steel tube sleeve is directly manufactured by sawing the seamless steel tube (1); and the outer surface of the seamless steel tube (1) is provided with a plurality of radial inverted trapezoidal grooves (2) formed through roll finishing, the inner surface of the seamless steel tube (1) which is located on the same part with the grooves (2) is provided with circular arc raised ring ribs (3) raised along with the deformation of the grooves (2) formed through rolling compression, and the inverted trapezoidal grooves (2) in the outer surface of the seamless steel tube (1) are distributed in a way of more at two ends and less in the middle by taking the central point of the seamless steel tube (1) as a boundary. The grouted deformed steel tube sleeve disclosed by the invention can be used for greatly reducing the expense of grouted cast steel abutted and connected by a load-bearing steel bar anchor in a prefabricated concrete member or the expense for cutting and processing a steel sleeve and simplifying the processing technology and can be directly applied to engineering practices.
