Ribbed bar sleeve extrusion joint and connecting method
The invention relates to a ribbed bar sleeve extrusion joint and a connecting method. The ribbed bar sleeve extrusion joint comprises a steel sleeve and ribbed bars at two ends, wherein the two ends of the steel sleeve are respectively sleeved with the end parts of the ribbed bars at two sides, and the extrusion joint is formed by once extruding the steel sleeve with the ribbed bars by an extrusion tool and an extrusion die; two or four symmetrical concave continuous extrusion rings are arranged at the middle part of the steel sleeve, the central axis of the concave continuous extrusion rings is coincident with the axis of the steel sleeve, the ring groove section of the concave continuous extrusion rings along the axis direction of the steel sleeve is an isosceles inverted trapezoid or a rectangle, the cross section perpendicular to the axis direction of the steel sleeve is an oval, and an included angle between bevel edges at two sides of the isosceles inverted trapezoid and the axis direction of the steel sleeve is 60-90 degrees; the inner surface of the steel sleeve, on which the concave continuous extrusion rings are positioned, is closely occlusive with ribs on the surfaces of the two ribbed bars; and the diameter of each ribbed bar is 8-14mm.
