Rebar Coupler is designed to produce a full-strength mechanical joint between reinforcing bars. Today, I will share with you how to detect the tensile strength of the  rebar coupler . Let's get a close look. 1. Process Inspection Before and during the construction of the steel bar connection project, conduct a process inspection for each batch of incoming splices. There shall be no less than 3 splices of each type of steel bar during process inspection. The base material of the splice specimen shall be taken tensile strength test. 2. On-site Inspection The on-site inspection of splices shall be carried out according to the acceptance batch, and the joints of the same grade, type, and specification of the same batch of materials shall be adopted under the same construction conditions. An acceptance batch of 500 will be conducted for inspection. For each acceptance batch of splice, three specimens must be randomly selected from the engineering structure for unidirectional tensile tes...

  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. Changsha DLADTO Rebar Splice Co., Ltd  is a professional rebar coupler ...

The advantages of the direct rolling straight threaded rebar couple r are: the thread processing is simple, the equipment investment is small, the disadvantage is that the thread accuracy is poor, and the false thread phenomenon exists. Due to the uneven thickness of the steel bars, large tolerances, and inconsistent thread diameters, the on-site construction is difficult, and the coupler and the thread head are inconsistent with the tightness, and some joints may be pulled off. Due to the change of the steel bar diameter and the influence of the transverse and longitudinal ribs, the service life of the rolling wheel is reduced, the additional cost of the joint is increased, and the vulnerable parts of the construction site are frequently replaced. Rolling ribs and rolling straight threaded reabar coupler: This kind of connection joint uses special extrusion equipment to pre-flatten the transverse and longitudinal ribs of the steel bars, and then roll the threads, the purpose is to red...
