Combined-type grouting sleeve connecting structure and steel bar connecting construction method

Abstract

The invention discloses a combined-type grouting sleeve connecting structure and a steel bar connecting construction method. The combined-type grouting sleeve connecting structure comprises a verticalsleeve body; an upper steel bar and a lower steel bar are inserted from the two ends of the sleeve body correspondingly; a plurality of bulged annular inner ribs are arranged on the inner wall of thesleeve body in the axial direction at intervals; a grouting hole and a slurry discharging hole which penetrate through the sleeve body are formed in the upper end and the lower end of the sleeve body; the ends, in the sleeve body, of the upper steel bar and the lower steel bar are connected with horizontal end plates correspondingly, and the diameter of the end plates is larger than the inner diameter of the annular inner ribs; the two end plates are located between any two of the adjacent annular inner ribs; and the sleeve body is of a two-half separable structure split by the plane passingthrough the axis of the sleeve body, and a constraint part is arranged on the outer side of the sleeve body, so that the sleeve body of the two-half separable structure keeps in the grouting use overall state. The grouting sleeve connecting structure adopts separating design, the integrity of a prefabricated part can be improved, and thus the quality and seismic performance are improved; and partsof processes are adjusted, the construction difficulty is lowered, and the efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of fixed buildings, and in particular relates to a combined grouting sleeve connection structure and a steel bar connection construction method. Background technique [0002] Prefabricated building is an energy-saving, environmentally friendly and efficient building form. Prefabricated concrete components have the advantages of high economic benefits, less impact on construction by climatic conditions, easy guarantee of product quality, short construction time and less environmental pollution, and have become an important direction for the development of the construction industry. With the development of prefabricated buildings, there are still many problems to be solved. Among them, the connection of steel bars is the key technology for the development of prefabricated structures. At present, the steel bars are mainly connected by grouting sleeves in the construction process, and the grouting sleeves with s...
