A crank bar is a type of reinforcement used in slab-bent up bars. It is used to help resist the bending moment at the end of the bar. The bar is placed at an angle to the main reinforcement and is connected to it using pins or bolts. The length of the bar is typically around 1.5 times the length of the main reinforcement.
Why crank bar is used in slab- bent up bar
- The crank bar is used in slab- bent up bar to provide extra reinforcement at the corners of the slab
- The crank bar increases the strength of the slab by distributing the load more evenly over the surface area
- The use of a crank bar also allows for a more aesthetically pleasing slab design.
Why do we use crank in one way & two way slab
- There are two main reasons for using a crank in slab design
- The first is to provide additional support for the slab during construction
- The second is to allow for traffic loads to be evenly distributed across the slab.
Why do we use crank in slab
- A crank is used in slab because it provides a way to lift the slab without having to use a crane
- By using a crank, the slab can be lifted by a few people without the need for heavy machinery
- This makes it much easier and cheaper to lift a slab, which is why it is such a popular method.
reinforcement (rebar) in slab
- etermining the amount of reinforcement (rebar) in a slab is an important factor in the design of the slab
- The purpose of the reinforcement is to provide additional strength and support to the slab, and to prevent cracking and other forms of damage
- The amount of reinforcement required will depend on the size and weight of the slab, as well as the location and purpose of the slab.
Conclusion
The crank bar is a versatile and effective tool that can be used in a variety of ways to create bent up bars in concrete slabs. It is easy to use and install, and has the potential to save time and money when compared to traditional methods.
