Steel bar full-grouting sleeve for prefabricated concrete strong connection
The invention discloses a steel bar full-grouting sleeve for prefabricated concrete strong connection. The steel bar full-grouting sleeve comprises a grouting sleeve body with a cavity provided therein, two ends of the grouting sleeve are steel bar insert segments with different apertures to connect vertical steel bars with different diameters, and are connected through a variable diameter through hole, the variable diameter through hole is provided with a steel bar spacing plate, the inner wall of the cavity in the grouting sleeve body is provided with rectangular projection shear connectors, adjacent shear connectors form an annular shear slot in order to enhance the binding occlusion force between a grouting material and the grouting sleeve, two ends of the grouting sleeve body are respectively provided with a grouting hole and a pulp discharging hole, and one end or two ends of the grouting sleeve body is/are provided with a structure for installing one or two sealing gasket(s). The steel bar full-grouting sleeve can solve the connection problem of vertical steel bars with different diameters in the prefabricated concrete strong connection, and ensures effective force transfer of the vertical steel bars with different diameters.
