The invention relates to a short-sleeve grouting steel bar connection connector and a connecting sleeve and pressure bearing rings arranged on the same. The short-sleeve grouting steel bar connection connector comprises ribbed connecting steel bars, the connecting sleeve, a cement based grouting material and the pressure bearing rings. The semicircular pressure bearing rings with the section being of a wedge-shaped structure are arranged in the portions, between end transverse ribs of the ribbed connecting steel bars, of the connector. The hole diameter of the end of a grouting connecting cavity of the connecting sleeve body is smaller than the diameter of an inner cavity of the grouting connecting cavity. By adoption of reducing holes of the wedge-shaped pressure bearing rings and the ends of the sleeves, when the steel bars are tensioned, the anchoring effect of the cement based grouting material on the ribbed connecting steel bars in the connector is remarkably improved, the connector length is effectively shortened, the original conditions of steel bars outside the connector are kept, construction is easy, rapid and low in cost, and when the short-sleeve grouting steel bar connection connector is used for connection of corrosion resistant steel bars and reinforcing stainless steel bars, it can be ensured that the connector has the corrosion resistance the same as that of the steel bars, and it can further be ensured that the mechanical performance of the connector meets the requirements of national and foreign related standards for the steel bar sleeve grouting connection connector.
