Extrusion semi-grouting reinforcement sleeve, connecting structure and construction method thereof
The invention relates to an extrusion semi-grouting reinforcement bar sleeve, a connecting structure and a construction method thereof. The sleeve is a hot-rolled seamless steel pipe, a grouting hole and a slurry outlet are formed in the tube wall of the sleeve, annular concave bulges are distributed between the grouting hole and the slurry outlet, one end of the sleeve is an extrusion end, the other part of the sleeve is the slurry anchor end, the internal diameter of the extrusion end is equal to the external diameter of each of connected reinforcement bars and is smaller than that of each slurry anchor end, and the grouting hole, the slurry outlet and the annular concave bulges are all positioned at the slurry anchor end. According to the extrusion semi-grouting reinforcement bar sleeve, the connection among the reinforcement bars is realized by the utilization of the semi-grouting reinforcement bar sleeve, one end part of the sleeve is connected with the reinforcement bars by adopting an extrusion connection technology, and the other part of the sleeve is still connected with the reinforcement bars in a grouting way; the extrusion semi-grouting reinforcement bar sleeve can be widely applied to the reinforcement bar connection of precast concrete columns in a multi-high-rise precast concrete frame structure and a shear wall structure or a frame shear wall structure, the horizontal reinforcement bar connection of a precast concrete beam, the reinforcement bar connection of the precast concrete shear wall and the reinforcement bar connection in an existing reinforcement project.
