The steel component known as a "rebar coupler" is what connects two rebars together. To make information easy to access, the product's specifications are written on a chart. Price and weight per ton are provided. For instance, our graphic highlights 12mm rebar as one of the common and significant ones. In reinforced concrete structures, rebar couplers or mechanical splices are used to replace typical rebar lap joints. This is done by connecting two rebar pieces together. The usage of the rebar coupler is also appropriate for application in reinforced concrete walls and columns. A rebar coupler is a section of rebar that has been modified at its right end to include a thread and a coupler sleeve. This modification is seen while looking in the direction of installation. Rebar couplers are an option for replacing individual sections of rebar that pass through the form work in building joints. In the construction business, rebar couplers are sometimes referred to as mechanical splices. Their purpose is to link the lengths of two reinforcing bars together. It is not always the case that lapped joints, which are the traditional method for attaching reinforcing bars, are the best option. The concrete itself is responsible for the passage of loads through lapped joints. The usage of laps can be time-consuming in terms of design and installation, and the additional amount of rebar might cause congestion within the concrete. Laps can also be used to join two pieces of existing rebar together. Couplers are devices that are created with the purpose of mechanically joining two bars together. Through the establishment of an end-to-end bar connection, it is possible to generate a load path that is uninterrupted from one bar to the next and which is unaffected by the state or quality of the concrete. Mechanical splices are reliable under situations of cyclic loading into the inelastic range and appear to be useful in the areas where inelastic yielding may occur. This is because mechanical splices are not affected by the cyclic loading. BENEFITS OF COUPLERS In contrast to lapping, in which the performance of the reinforcement entirely depends on the concrete, spliced rebar acts in the same manner as continuous reinforcement due to the mechanical junction. 
The amount of wasted steel has greatly decreased. By utilizing couplers, lap length steel can be saved. A rebar that is 12 meters long can be cut into bars that are either 3 or 4 meters long, depending on what is necessary, which helps prevent the waste of steel end pieces. There is no requirement for the bars to be staggered. The area of the bar's cross-section is not diminished. Couplers are utilized in place of dowel bars, which not only helps save form work material but also space. Because laps are no longer used, there is less congestion in the steel industry. When compared to lap joints, the cyclic performance of systems that use couplers is significantly higher. Simple to put in, and there is no need for a torque wrench. FEATURES OF COUPLERS The production of couplers frequently involves the usage of EN material. Couplers for reinforcing bars that have a high carbon content not only have a high strength but also a greater thickness, which makes them more effective and sustainable. The use of a reinforcing bar coupler can help to speed up the execution of projects while also improving their overall quality. It is possible for it to simplify the design and construction of reinforced concrete, as well as reduce the amount of reinforcement that is required, which is now an important national resource. It is not necessary to use a torque wrench in order to assemble reinforcing bar couplers. 
Rebar coupler 12mm
All rebar couplers are available for steel rebars in a variety of sizes, such as 6mm, 8mm, 10mm, and 12mm. Rebar couplers are components that, along the length of two reinforcing bars, mechanically connect them together to form a single bar. These connections offer an alternative to the more traditional methods of welding and lap splicing. Utilizing mechanical splices helps to prevent rebar from protruding out of casting joints, reduces congestion in confined spaces, and conserves material. Producing and attaching rebar couplers to the rebar uses a variety of different technologies, which results in rebar couplers with a wide range of properties, including tensile capacity, robustness under real site conditions, assembly simplicity, and control over the correct installation of the couplers. Taking into consideration these aspects will assist you in selecting the most suitable alternative for the task at hand. Utilizing HRC couplers for the rebar The high-performance HRC400 rebar couplers are capable of dealing with any situation. The mechanical join that is created by the HRC-coupler is far more robust than the rebar itself. Excellent work! Series HRC400: rebar subjected to loads and pressures that exceeded its limit capacity The ductility of the rebar is maximized to its fullest extent (the result is like an UN-spliced bar) Improves the designer's capacity for flexibility (all couplers can be placed in the same section) The HRC400 features a user interface that is both straightforward and easy to use, in addition to its dependable structural performance. It is absolutely necessary that the installation be carried out in a correct manner if the mechanical splice is to function in the appropriate manner. 
On a technical level, the HRC400 Series complies with a number of European standards and certification processes. These standards and programs may be found in Europe. Take, for example: BS 8597 (UK) Guidelines for the Approval and Monitoring Testing of Mechanical Betonstahl Connections are referred to by the acronym D.I.B.t (Germany) BRL 0504 Kiwa (The Netherlands) NF A35-020 (France) BY4B (Finland) This document, which is known as the "Boverkets handbook om betongkonstruktioner - BBK," is the official handbook on building construction that is published by the government (Sweden). Direct evidence that all necessary conditions have been satisfied can be gleaned from certifications already issued and test results already obtained. Tensile testing will always result in the parent rebar breaking, even if the actual rebar strength is far lower than the ultimate tensile stress of more than 700 MPa. This is because the ultimate tensile stress is greater than this value. It is extremely difficult, if not impossible, to construct buildings made of reinforced concrete without overlapping the reinforcements at some point throughout the process. This is because of blatantly obvious factors, such as the convenience of transport and handling. 
When installed in a vertical posture, reinforcements become unstable under their own weight when the length of the reinforcements reaches particularly lengthy lengths. Lapping, also known as reinforcement splicing, is a time-honored method that has been utilized for many years to unite two distinct reinforcements in the course of construction. However, in more recent times, mechanical splices have been invented. These splices, such as rebar couplers, make it possible for two distinct sections of reinforcement to be linked together and act as if they were "one continuous unit." The following are the three primary techniques that have been identified for reinforcement splicing: Lap splices Splices that are welded, as well as mechanical splices It is well knowledge that when reinforcements are lapped in the usual manner (also known as lap splices), load transfer between the two rebars will be dependent on the bond formed by the concrete. However, when mechanical splices are used, concrete is not required for load transfer. This is because the two bars have a tendency to behave as if they are a "continuous unit." In addition, the concept of lapping is inherently inefficient and can result in a significant increase in the amount of reinforcement that is packed into a particular piece of a concrete component. Welding of bars, on the other hand, is regarded as a more pricey method that may depend on the chemical qualities of the reinforcing bar in order to achieve acceptable weldability. 
Rebar coupler per tonne
Rebar couplers are offered by our manufacturers at a range of costs per tonne. To eliminate the need for the traditional method of lapping and welding reinforcement into RCC buildings, rebar couplers are employed. Lapping system is used when long length bars are required or when joining the additional bars to the end of existing bars by tying them by wire next to each over. Lapping and welding are similar processes, but in welding the bars are joined together mechanically rather than joined together by wire. Rebar couplers, also known as the coupler in reinforcement, are used as an alternative to the traditional lapping and welding systems because they allow for continuous reinforcement of a structure without the need for unnecessary material waste. In comparison to the lapping system, where a portion of the bar is wasted due to lapping, the coupler in reinforcement is used because it is more cost-effective. For large diameter bars used in mega-projects and skyscraper construction, the rebar coupler is an economical choice. Rebar couplers can also be referred to as mechanical splices. The rebar coupler has widespread application in the building industry, including the erection of structures like houses, bridges, dams, towers, and many others. Various Couplers for Rebar Reinforcing applications typically use one of two basic kinds of rebar couplers, such as Roll Rebar Coupler Threaded Rebar Coupler Rebar Joiner, Cold-Forged Rebar Coupler with No Threading Coupler for Crimping Rebar Coupler for MBT Rebars Coupler for Rebar with a Roll Thread The coupler in a roll thread rebar coupler is threaded using a threading machine. The ends of the TMT bars are threaded in a Roll Thread Machine so that they can be used with a roll thread coupler in reinforcing applications. 
After that, rebar couplers are attached to both ends of the TMT bar, just like nuts and bolts, to ensure the reinforcement is continuous. Insulated Rebar End Connector Cold Forged Rebar Couplers are threaded in the same way that Roll Thread Rebar Couplers are, using a threading machine. A forging machine uses hydraulic pressure to forge the end of a TMT bar into a coupler for use in reinforcing. TMT bar ends are threaded by a threading machine and then attached to a rebar coupler, after which they undergo a forging process, during which they lose a little amount of length and gain thickness. In large-scale government and infrastructure projects, the cold-forged rebar coupler is approved. The government of India has officially approved this system, and it has been given the BIS code IS: 16172-2014. Rebar Crimping Coupler The first coupler used in reinforcement was a crimping rebar coupler, and later on the threaded rebar coupler was developed. There is no thread in a crimping rebar coupler. With the TMT bar's ends threaded, a rebar coupler sans thread is inserted and crimped using a crimping machine. The crimping coupler is wasteful due to the high cost of materials and labor required to make it. Reinforcement crimping couplers are irreversible once installed. The crimping rebar coupler technology has been a commercial failure for these reasons. MBTC Rebar Joiner For the most part, the MBT Rebar Coupler is made to withstand the extreme stresses of constant reinforcement. For situations when there is insufficient bar length for continuous reinforcement and the lap length is short, this MBT coupler in reinforcement can be employed. Retrofitting buildings also make use of MBT couplers. A single MBT coupler has anywhere from six to eight bolts in the top. In comparison to a threaded coupler, an MBT coupler is longer. Depending on the number of bolts used to secure the coupler in reinforcement, MBT couplers can be extremely strong. 
Rebar coupler 12mm price
We have information about the rebar couplers available, including one of the most significant sizes, 12mm. Our list includes information about the features and the price. Lapping of rebars has been used for a long time as an efficient and cost-effective splicing procedure; nevertheless, modern concrete constructions require more advanced techniques. Splicing rebars is a necessary part of the construction process for practically every reinforced concrete building. It's possible that the desired bar length is greater than the available steel stock length, or that the bar would be too long to ship easily. The result is the same either way: the rebar installers will have two or more steel pieces that need to be joined together. Lap splicing, which involves overlapping two parallel bars, is widely recognized as a reliable and cost-effective splicing technique. However, things have changed in the recent past. Lap splicing, a type of mechanical splice, has fallen out of favor as a result of advances in technology, more complex designs (especially in concrete), the introduction of new materials, and the rise of composite materials. Mechanical splices are connections between rebar sections that are made mechanically and allow the sections to function as if they were one continuous bar. Rebar can be joined together using mechanical splices, which provide many of the same benefits as using one long piece of rebar. For this reason, they are more dependable than lap splices, which rely on concrete for load transfer. 
A variety of mechanical splices are now available to facilitate the rapid and simple establishment of a connection that is both precise and reliable.
