Bar Bending schedule से जुड़े कुछ महत्वपूर्ण Topic

 

Introduction:-

A bar bowing timetable is a way to figure the specific amount of fortifications needed in construction. It is useful for any solid work to know the specific measure of concrete, total, or sand needed for a design. It is alluded to as BBS in a short structure. It includes figuring advancement length, the distance across bars to be utilized, stirrups, cutting length, wrench length, and some more. It is an interaction of cutting and twisting support bars into the wanted shape and size according to the primary drawing. These drawings are given by primary specialists for different underlying components like balance, segment, bar, section, and so forth, and afterward gave over to workers for hire for the execution of the work at the site by the workers. The project worker should comprehend it inside and out before depicting it to the workers. BBS is important to the worker for hire as it is significant in offering tenders. Every one of these works assumes a significant part without which work can't continue. 

Advantages:-

 Some of the upsides of BBS are – 

•  Gives exact data of fortifications to be utilized in concrete underlying individuals, because of which, all-out fortifications needed in a design can be determined. 

•  Gives a decent insight to the architect with regards to how much observing work will be needed for carrying out the BBS. Decreases additional endeavors and saves time.

 

•  With this, an additional measure of fortifications can be deducted from the assessment charging and cost can be diminished that will end up being efficient. 

• Works can find out about cutting bars heretofore and in this manner, a lot of additional endeavors to carry out the work will be decreased. 

• Venture the executives will be simple and the assessed season of finish will be more functional. 

• It will help quality control to screen the nature of work and point out the deformities in advance. 

• Charging will be speedy and simple and customers can get charges path before time. Any progressions to be caused will get conceivable absent a lot of issues. 

• At the point when utilized Fe 500 rather than Fe 415, the expense will be decreased by around 10% which is gainful to the customer searching for a less expensive other option. 

How to get ready? 

Given underneath are the means for the readiness of BBS – 

•  Right off the bat, it is essential to bring up the measure of steel needed for different underlying individuals. This can be discovered with the assistance of a format or drawings. 

• Furthermore, it is needed to tally the quantity of rebar having various shapes and it is to be noted down in the bar bowing timetable. 

• Then, the length of the support bars is determined which is helpful in amount assessment. 

•  At that point, the unit weight of support bars is determined for figuring the amount or volume. 

• At that point the heaviness of a specific state of the bar is determined as follows: 

         Weight of Reinforcement Bar (Shape of Bar) = No of Bars X Length of Bars X Unit             weight of Bar.

•    This will give the absolute load of a particular shape bar in kilogram which is the SI              unit. 

Precautions:-

It is imperative to remember the accompanying focuses as certain missteps are normal in BBS which costs a great deal of cash to the customers. Some of them are – 

•  Frequently it is seen that number of bars is miscalculated which influences the entire interaction along these lines, this should be remembered. 

• The measurements taken from designs or drawings should be exact. It is regularly seen that slip-ups are made in perceiving the unit from the drawing and thusly, estimation blunder happens. 

•  Different components like length are frequently misjudged as additional length for cutting is here and there missed by engineers. In this way, it is another significant basis for exact estimations and computations. 

• The bars should consistently be portrayed as story-wise beginning starting from the earliest stage and afterward continuing towards particular floors upwards. 

• For each primary component, the bars should be gathered. This ought to resemble shafts and segments for each floor and afterward continue towards different floors. The equivalent applies to other primary components as well. 

• For cutting and twisting purposes, a different A4 sheet is needed to decrease disarray. Additionally, these ought not to be remembered for the drawings where insights regarding fortifications are given. 

• The bars should be requested according to mathematical requests. This portrays a more clear vision for the project work while understanding the agreement. 

• Welding is evaded at the twists so derivations should be made there. 

•  Regularly utilized fortifications bar measurements are – 6 mm, 8 mm, 10 mm, 12 mm, 16 mm, 20 mm, 25 mm, 28 mm, 32 mm, 36 mm, 40 mm. Though the standard length of the support bar is 12 m. 

• Weight per bar is communicated as Weight of Bar per meter X Standard length of the bar. 

Conclusion:-

Bar twisting timetable assumes a significant part in structural designing and it is viewed as a significant apparatus in building construction. Any progressions made in the bar twisting timetable are joined by changes in the agreement concerning the cost and project of the executives. It straightforwardly connects project executives and execution time in the field or site of development. Any blunder in this will influence time, expenses, and labor so it is encouraged to deliberately figure the amount to stay away from any mix-ups in computations. Likewise, it is encouraged to follow the particular nation's codes to dodge any disarray like in India it ought to be followed according to IS code thus every nation will follow diverse equations and techniques.
