Hole-type steel tube concrete pier stud

The invention discloses a hole-type steel tube concrete pier stud, which comprises a pier stud body, wherein the pier stud body comprises a steel tube, an inner-packed concrete layer and an outer-packed concrete layer; the inner-packed concrete layer is filled in the inner cavity of the steel tube; the outer-packed concrete layer is poured around the steel tube; and the inner-packed concrete layer, the steel tube and the outer-packed concrete layer are connected into a whole by through holes arranged in the tube wall of the steel tube. Therefore, the hole-type steel tube concrete pier stud has a better load bearing performance and is convenient to construct, complex reinforcement processes are avoided, and the problems of corrosion prevention and internal disengaging of the steel tube concrete are effectively solved.
