Although the advantages of   mechanical splices   are well recognized, a major concern has been their high cost for applications where the codes permit the use of lap splices. But is the perception that mechanical splices cost more than lap splices a reality? By using couplers, contractors can be more cost efficient, able to achieve from 20-50% of cost savings compared to lap splicing. Apart from that, there are many other savings which can be anticipated such as; Reduction no. of joints 6 meters length will be most ideal for joining and this would result in reduction of no. of laps by, Assuming height of building: 100 metres Typical floor height: 3.2 metres No. of laps: 100 / 3.2 = 31 laps No. of coupler joints: 100 / 6 = 16 joints Therefore reduction in no. of laps: [(31-16)/31] x 100% = 48% Minimal wastages of HTDBs Assuming floor height of 3.2m and lap length of 1.275m Length of steel bar per floor is : 3.2m + 1.275m = 4.475m For a 12metres steel bar, two nos of 4.475metre...

 In the construction industry, various steel bars are used in a very wide range of situations. It is known that the length of steel bars is limited. Sometimes the steel bar is too long and people will cut it, and sometimes we also need to connect them. If the cut steel bar is not very long and connected with welding technology, it is not only time-consuming, but sometimes the labor cost of connecting the steel bar is far beyond the use of the value, and such a practice often does not pay for itself. Now the rebar coupler is a new product designed to replace the traditional welding method. Instead of using the old connections method, the rebar coupler uses new technology to connect steel bars without any electrical support. The rebar coupler adopts the international standard 45 steel, so that the product has unexpectedly super hardness, to ensure firmness and stability during use. The rebar splicer and coupler has an exquisite design and high precision, which effectively ensures tha...

The   parallel thread rebar coupler   is a steel sleeve for the mechanical joint which transmits the axial tension or pressure of the steel bar. The connection method of the parallel threaded rebar coupler is to strip off part of the longitudinal rib and transverse rib of the end of the steel bar by cutting with a wire rolling machine, and then roll directly into ordinary parallel thread, and connect with the special parallel rebar coupler to finish the connection of the steel bar. So, how do we check its connection quality? 1. Appearance inspection of construction quality: (1) Check whether the crimping pattern conforms to the plan, why the coupler rusts, and whether the coupler is under pressure. The small indentation of the joint shall conform to the standard. (2) There should be no visible cracks on the appearance of the joint.  (3) The curvature of the joint is 40. (4) At both ends of the joint, the steel bars have inspection marks. (5) During the appearance inspecti...

The parallel threaded rebar coupler connection is that a part of the longitudinal and transverse bars at the end of the steel bar is cut and peeled by a wire roller and it is rolled directly into ordinary parallel threads, then the special  parallel thread rebar coupler  is applied to form a steel bar connection. The technology of rib stripping rolling parallel thread connection has reached the advanced international level. Rib-stripped parallel threaded coupler connection technology is favored by the majority of construction units and owners due to its advantages of convenient construction, energy saving and consumption reduction, improved production efficiency, and stable and reliable connection quality. It is a new product of parallel thread connection technology. When using the parallel steel thread coupler, pay attention to installation precautions to avoid unnecessary technical problems that may affect the quality. 1. Steel bars in place: Move the steel bars that have p...

Rebar couplers, also known as mechanical splices, join the lengths of two reinforcing bars together. The rebar coupler is roughly divided into  cold extrusion rebar coupler , straight thread rebar coupler, left and right-hand rebar coupler, welded rebar coupler, coupler with different inner diameters, etc. The application of mechanical splice has been very useful in some construction sites. But why are some prices high and others low?    The price of the rebar coupler is related to: 1. The price of the rebar coupler is related to its specification. Typically, there are 18, 20, 22, 25, 28, 32, and other specifications.     2. The price is related to the steel market. The ups and downs of rebar couplers follow the steel industry. 3. Th price is related to the quality of the  rebar coupler . The better the processing quality and the more the detection process is, the cost will be high and the price will be high. 4. The price is related to manufacturers. ...

Steel Bar mechanical splices include various types: parallel threaded rebar coupler,   upsetting forged rebar coupler , cold extrusion rebar coupler, grouting rebar coupler, split-type rebar coupler and so on. Parallel threaded rebar coupler can be divided into rib stripped parallel rebar coupler and parallel threaded coupler for splicing rebars with threads roll on to rebar end. Regardless of the type of coupler, the specification is named after the specification of the steel bar to which it is connected. For example, the coupler connecting 25mm steel bar is called the 25mm coupler.  At present, the specifications of rebar couplers are 12, 14, 16, 18, 20, 22, 25, 25, 32, 36, 40, 50, and there are also left and right hand thread rebar coupler and coupler with different inner diameter. For example, 25/28 left and right hand thread rebar coupler; 28/22 different inner diameter  rebar coupler .  In the process of using mechanical splice, the specifications and models o...

  Rebar couplers  are components which connect two reinforcing bars in longitudinal direction, forming a  mechanical splice .  According to the requirements, the diameter of 10~50mm steel bar straight thread rebar coupler can be made. So, what are the advantages of rebar coupler?  1. Convenient connection: even in a narrow place where the rebar is dense it can also operate flexibly. Convenient construction and high efficiency: the steel bar connecting sleeve is prefabricated by the factory, and the quality is guaranteed. Each group of wire rolling machine equipment has nearly 400 machinable joints, with incomparable advantages, no pollution during construction, and no open fire.  2. Easy to inspect: Do not need to use specific inspection equipment, and you can measure the quality of the splice by checking the thread of the steel bar. Strong applicability: applicable to the reinforcement connection of all seismic and non-seismic reinforced concrete structure...

Mechanical splice  is superior in transfer loads because it creates a direct mechanical connection at the junction of two rebars, which looks like a naturally elongated rebar. In general, mechanical splice have the following advantages: 1. Improved structural integrity 2. Improved design options 3. Ideal balance of steel and concrete by reducing unnecessary use of rebar 4. Reduced crowding and weight of concrete structures. 5. Reduced the amount of carbon dioxide produced by construction 6. Reduced the cost of rebar 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.
