Upsetting straight-threaded steel bar connection  technology is to first upset the end of the steel bar, make straight threads on the upsetting section, and then use the connecting coupler of the rib thread to connect the steel bar. The technology consists of steel upsetting technology and straight thread making technology. The cold heading process is the main method for upsetting. Through the cold heading process, not only the cross-sectional area of the end of the steel bar is enlarged, but also the yield and ultimate strength of the steel are improved after the steel bar is processed by cold heading, so as to ensure the high strength of the joint. on the strength of the steel base material. The upsetting of the steel bar is realized by a special steel bar upsetting machine. On the upsetting section of the steel bar, a special steel straight thread threading machine is used to process the upsetting section of the steel bar to make a straight thread. The upsetting straight threaded s

  Rebar couplers , also known as mechanical splices or mechanical coupler, are used to join lengths of rebar together to transfer forces from one steel rebar to another. The mechanical couplers can be an advantages in comparison with conventional methods of lap splicing because of requirement of less steel for overlapping.  It is more effective in the seismic detailing to avoid reinforcement congestion problems. The couplers are also used in pre-cast construction. It has several different types such as cold extrusion couplers, psetting forged rebar couplers and so on, which can be used in different conditions. Any two bars of same or different diameters are joined using the couplers by rotating like nut and bolt. Changsha DLADTO Rebar Splice Co., Ltd   is a professional rebar coupler producer, we have been in this field for a long time with customers for all over the world.  We are glad to help if needed, please feel free to contact us.   Click here to visit our official product site.

  Grouting coupler  is a combinator of coupler, grouting material and rebars.  By filling rapid hardening and no shrinkage material into the coupler, the couplers and rebars will be able to get a good grip between each other.   Grouting rebar couplers has several benefits, such as reliable, simple and easy to install, can be widely applied and so on.  It is a new mode that remedies the defects of traditional steel connectors(welding and bolts), and it has been developed and applied rapidly. Grouting rebar couplers are capable of and widely used in a large number of industries, including but not limited to reinforced concrete structure, steel structure, bridge construction, marine petroleum extraction and offshore wind power.

The steel bar thread rolling machine is a machine that uses the advanced technology of stripping and rolling to process the straight thread of the connecting end of the steel bar. The straight thread metal fiber of the steel bar processed by it is continuous and dense, and the comprehensive mechanical properties are good. The tensile strength is increased by 20%-30%, the fatigue strength is increased by 40%-60%, and the corrosion resistance is increased by 50%-200%. The steel rolling straight thread connection technology is suitable for industrial and civil buildings, and it is required to make full use of the strength and ductility of the steel for the connection construction of the rigid, oblique and horizontal steel bars in important parts of the structure. It has a simple and fast process, can be prefabricated, has no open flame operations, does not pollute the environment, has no hidden dangers of explosion and fire, is safe and reliable, can be constructed around the clock, and s

The  cold extrusion rebar coupler  is a portable system used for rebar connecting. It is a easy and effective way to connect rebars, no need to prepare two ends in factory in advance. The shells are powered by independent power unit, the hydraulic tool are squeezed on the steel plate. The final connection ensures that tensile strength of at least 125% of the nominal yield strength of the reinforcement grade 500 MPa. A simple step by step execution of cold-forged gripping the rebar coupler against the rebar by means of hydraulic press results in a full compression coupler. Its tensil strength is more than 125% of  a normal steel bar. For repair work or connecting two rebars with different diameters, all the cold shear cut bar ends are fitted. Fast installation and doesn't reduce the cross-section area of the rebar.

  Upsetting forged rebar coupler , also known as rebar connectors, rebar splicings and mechanical rebar couplers.  It is a rebar joint on the parallel line, specially designed for reinforcement bars and it is usually used with rebar threaders. Rebar couplers are widely used in reinforced concrete structures to replace traditional reinforcement lap joint. This kind of rebar coupler belongs to upset forging technology. Upsetting forged couplers are parallel thread couplers that can expand the minimum diameter of a rebar by cold forging and recutting. Several characteristics and advantages are included: ①It is fitted with different diameter rebars. ②The upsetting forged rebar coupler doesn't reduce the size of cross sectional area, it can make sure 100% bar breaking performance. ③Easy to install, no torque wrench needed. ④High efficient and low cost. ⑤Safer and quicker than lapping, welding and splicing.
