Rebar coupler is used to connect the two rebar ends in the construction work. 1. Easy Operation, saving time and rebar material. The rebar coupler producing and rebar end threading will not be affected by the weather; it can be processed before processing. 2. It can connect the rebar with the diameter 14mm to 40mm. 3. Use No.45 steel, with the thickness and length of the rebar coupler, the connecting part has higher tensile strength than the rebar part. size16-40mm.
The material of the cold extrusion rebar coupler is no.20 steel. The features of this technology: 1.Strong intensity connector, stable and reliable; no specific requirements on the weld ability of the rebar; 2.Only needs 1-3m to stamp each connector, which is about ten times faster than ordinary welding; 3.Only 1-3 kw power of oil pump , which is not limited by power capacity, has flexible structure and suitable for operation on several machines; Yj650 stamping equipment 4.No flammable gases, not affected by rainy or cold weather; 5.Relieve congestion of the connecting point, facilitated concrete pouring; 6.No professional and experienced worker needed, able to connect changed steel bar of different diameters; 7.Save 80% of connector steel consumption. The technology is assessed by the ministry of construction as "world advanced, high quality, high efficiency, safe, and economical thick diameter distorted steel bar connection technology which can be widely used in the construction industry." Cold extrusion application principle: 1.Place it well at the working point. 2.Directly use it to press connection point with screwless couplers to link the two rebar. -
The material of the splicing coupler is constructional quality steel of no.45 steel. Working principle: 1)slice up the end of the rebar; 2)peel the rib of the end of rebar with specialty rib peeling parallel thread rolling machine; 3)connect the two ends of rebar with rib peeling thread coupler; The characteristics of the usage: 1.Standard model: used in the occasion for connecting the steel bar in normal situation. 2.Different diameter model: used for connecting the steel bar in different diameters. 3.Flared model: used for the steel bar which was hard to match. 4.Positive and negative screw thread model: used in the occasion when the two sides both can not be turned but the lengths can be adjusted. 5.Locking nut model: used when the steel bar can not be turned, then it turns the splicing coupler to join the steel bar and then lock the splicing coupler with the locking nut.
Advantages: Bar-break feature guarantees fully ductile elongation. No reduction of the bar cross-section area. Working principle: 1, first, we use gq50 rebar cutting machine to splice up the end of rebar. 2, secondly, we use upset forging parallel thread machine (bdc-auto1 machine) to forge the end of rebar. 3.Third, we use parallel thread cutting machine (lw-i500 machine) to thread the ends of the rebar which have been forged. 4.Fourth, an upsetting coupler is used to link the two ends of rebar in parallel thread.
Application guide: Proper installation is very important to ensure the design load will be reached in the application. Yida strongly recommends that the installation and site quality check be done according to the required guidelines and dimensions. Site installation method: 1.Screw the bolt into female coupler swaged with rebar, till unable to screw continually. 2.Screw another side of bolt into the other sleeve after swaged with rebar, till unable to screw continually. 3.sWith the help of two pipe wrenches, tighten the connection by turning both rebar/couplers in opposite direction at the same time.

Standard taper thread couplers are designed to splice the same diameter bars where one bar can be rotated and the bar is not restricted in its axial direction. It is designed to achieve failure loads in excess of 115% of the characteristics stregth of Grade 500 rebar end. Transition taper thread couplers are designed to splice different diameter bars where one bar can be roated and the bar is not restricted in its axial direction. Working principle: 1.Slice up the end of rebar. 2.Make the rebar taper thread cut by taper thread machine. 3.Connect together two taper thread ends by one piece of taper thread coupler.
