Detailed Description
The first embodiment of the reinforcing steel bar connecting device.
A steel bar connecting device comprises a taper sleeve 1 sleeved on a steel bar, wherein the taper sleeve is provided with a tapered through hole along the axial direction, and a locking plate 2 with one side attached to the tail end of the connection of the two steel bars; the two taper sleeves are respectively sleeved at the opposite tail ends of the two steel bars, and the taper sleeves on the steel bars are arranged towards the other steel bar by one end of the conical bottom surface of the through hole; a plurality of locking plate along the terminal circumference setting of reinforcing bar, one side of locking plate dorsad reinforcing bar is along middle part toward both ends towards the reinforcing bar slope.
Reinforcing bar connecting device, locking plate 2 is equipped with the arc concave station unanimous with the reinforcing bar surface towards one side of reinforcing bar, makes the locking plate laminate on the reinforcing bar more steadily to can improve the joint strength between locking plate and reinforcing bar, the adjacent reinforcing bar.
The steel bar connecting device is provided with an annular positioning ring 3, and the positioning ring is sleeved in the middle of the outer side of all the locking plates 2 attached to the steel bars along the circumferential direction. The locking plate is preliminarily positioned on the steel bar through the positioning ring, and the taper sleeve is knocked into the locking plate, so that the convenience of operation can be improved.
The second embodiment of the reinforcing bar connecting device.
A steel bar connecting device comprises a taper sleeve 1 which is provided with a through hole along the axial direction and is sleeved on a steel bar, and a locking plate 2 of which one side is attached to the tail end of the connection of the two steel bars; the locking plates are arranged along the circumferential direction of the tail end of the steel bar, and one side of each locking plate, which is back to the steel bar, inclines towards the steel bar from the middle part to the two ends; the two taper sleeves are respectively sleeved at the opposite tail ends of the two steel bars, inwards concave locking platforms are respectively arranged on the inner wall of each taper sleeve through hole and opposite to each locking piece, and the depth of each locking platform is gradually decreased from one end of the other taper sleeve to the other end; the rest is the same as the first embodiment.
