#Splice bars manual
For projects of all sizes, Manual arc welding will usually be the most costly method, due to direct and indirect costs of proper inspection. If lap splices are not permitted or impractical to use, mechanical connections or welded splices must be used. In conclusion, each splice method has its advantages and suitability for particular applications. 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. other types of mechanical rebar splicing systems will just grip the rebar without the need of having threaded rebar at the job site. These rebars must have threaded rebar ends to fit into the coupling and then the splice is tightened onto the rebar. Normally, mechanical splices use a metal device to coupling to connect two pieces of rebar. To help solve these problems, the industry has also used mechanical devices to generate rebar splices. it is not permitted to use lap splice for #14 and #18 bars except in compression, only for #11 or smaller bars. Lap splices cause congestion at the splice locations, sometimes making their use impossible Splicing rebars at critical stress points Rebar congestion making it difficult to concrete to pass trough Insufficient lap splice length Determining splice length when using different types of rebar In addition.
However, lap splicing also brings some problems during the construction process. Lap Splicing is generally the most common and usually the most economical splice and welded splices usually require the most expensive field labor.
