Abstract
The utility model provides a strong taper thread sleeve steel bar joint connection method, has solved prior art and has turned the system screw thread under the condition that does not increase the original size of reinforcing bar end promptly for the diameter of reinforcing bar diminishes, and intensity receives great weakening, and the reinforcing bar connects rather than the body is not strong, brings very big quality hidden danger for the engineering, can only reach B level in the joint evaluation, and its application in the engineering receives the not enough of very big restriction. It is characterized by that the ends of reinforcing bar to be butt-jointed are firstly upset into tapered form, on the tapered form the screw threads are turned, and finally they are screw-connected together by means of sleeve joint. The strength of the joint and the body is equal, the grade evaluation can reach A grade, and the joint can be used for butting the reinforcing steel bars together.
Description
The present invention a kind ofly is docked to together method, particularly a kind of connecting method of equal strength taper thread sleeve reinforced bar joint with two reinforcing bars.
Taper thread bar splice technology conventional in the prior art is in engineering, especially obtained using widely in civil works.Its objective is two reinforcing bars are docked to together.Its method is at the termination of two reinforcing bars thread cutting, by the joint that contains internal thread two steel bar ends is screwed onto together again.But its weak point is, thread cutting under the situation that does not increase the original size of steel bar end, make the diameter of reinforcing bar diminish, its intensity is subjected to bigger weakening, bar splice and its body do not wait by force, bring great hidden danger of quality to engineering, in the bar splice ranking, this structure only can reach the B grade standard, makes it be subjected to great restriction in application in engineering.
The objective of the invention is to solve above-mentioned weak point of the prior art, and a kind of connecting method of equal strength taper thread sleeve reinforced bar joint of thread cutting again that will dock behind the steel bar end jumping-up is provided.
Technical solution of the present invention is: the shape that earlier steel bar end of desire butt joint is upset as tapering, car system taper thread 2 thereon again, the thick head of the upset end after the car system should be greater than or equal to the diameter of mother metal 3, with the muff joint that includes taper thread that processes in advance 1 it is screwed to together at last.
The advantage that the present invention is had compared to existing technology is: bar splice and reinforcing bar body etc. are strong, can not weaken its intensity because of thread cutting thereon.The bar splice ranking can reach the A grade standard.
This accompanying drawing is an overall structure schematic diagram of the present invention.
The present invention is described in further detail below in conjunction with embodiment: earlier with the reinforcing bar of desire butt joint (diameter whether identical all can) termination jumping-up, car system taper thread 2 thereon again guarantees that the thick head of the upset end after the car system is answered 〉=diameter of mother metal 3.With the muff joint that includes taper thread that processes in advance 2 it is screwed to together at last.Can reinstate for reinforcing bar is docked to one.
Claims (1)
1, a kind of connecting method of equal strength taper thread sleeve reinforced bar joint, at the termination of two reinforcing bars thread cutting, by the joint that contains internal thread two steel bar ends are screwed onto together again, it is characterized in that earlier the steel bar end of desire butt joint being upset as the shape of tapering, car system taper thread 2 thereon again, the thick head of the upset end after the car system should be greater than or equal to the diameter of mother metal 3, with the muff joint that includes taper thread that processes in advance 2 it is screwed to together at last.
