Usage Bar Bending - In the construction of infrastructure in several countries, such as the construction of high-rise buildings, roads, railways, bridges, etc., there are still many that we may not mention one by one in this article. In this case, of course in the construction of structures in concrete construction work will require a lot of heavy equipment that can support the success of the work. The construction of this concrete structure will require iron or steel to strengthen the building structure.
So that one device is needed that can reach the process of working on building design structures. By using Bar BendingBy using Bra Bending, all construction industries will be more affordable because by using Bra Bending, strength, durability, and light weight will be formed. In addition, this Bending Bar is also very much needed for the formation of portable manual reinforcement made of various elements such as the center shaft, stationary backup roller, etc.
Workmanship in construction projects is not an easy thing to do, because a building is built of course aims to be occupied / as a place to live either as a house, building, institution, road or other which if the condition is not good will be at risk to everyone who uses the building, including the workers who work on it.
For steel, aluminum, and stainless, you will find various ratios of minimum bending radius to thickness, and you will need to research these values in the data provided by your material supplier. However, when researching these values, be aware that transverse (across the grain) or longitudinal (with the grain) bending will have an effect on the minimum bending radius required. Longitudinal bending requires a larger radius than stated for transverse bending (There are several stages to be able to perform the bending process. This is called the Bar Bending Schedule Bar Bending Schedule which is a list of reinforcement definitions for each structural element that includes the mark, shape, size, location, length, and bending details of the reinforcement. This Scheduling process is also called BBS.
As below example rod bending scheduleThis is because each structural element will be prepared separately both for each floor and for the entire building.
We have discussed the use of bar bending for different structural elements such as:
- schedule Bending Rods for plates
- Rod Bending schedule for beams
- Rod Bending schedule for columns
In addition, the application of the Bar Bending Schedule (BBS) usually has five steps before using it, such as:
- Calculate and find the number of reinforcement bars to be used
- Find the cutting length of each bar
- Calculate the number of stirrups or calculate the amount of distribution reinforcement if it is a plate
- Finding the cutting length of stirrups or extra bars (top bars)
- Record all bar and steel counts into a table
