There are three methods for rebar splicing:
To help solve these problems, the industry has also used mechanical devices to generate rebar splices. Normally, mechanical splices use a metal device to coupling to connect two pieces of rebar. These rebars must have threaded rebar ends to fit into the coupling and then the splice is tightened onto the rebar. other types of mechanical rebar splicing systems will just grip the rebar without the need of having threaded rebar at the job site. Some of these mechanical rebar splicing systems can be installed fast and easily with hand tools; It is the ability to be used on large rebar grades; It will perform as a continuous piece of rebar, on the another way, it has a superior fatigue performance.
In conclusion, each splice method has its advantages and suitability for particular applications. If lap splices are not permitted or impractical to use, mechanical connections or welded splices must be used. For projects of all sizes, Manual arc welding will usually be the most costly method, due to direct and indirect costs of proper inspection. Mechanical connections are made with proprietary splice devices. Performance information and test data should be secured directly from manufacturers of the splice devices.
