यह लेख इस बारे में है कि कॉलम के लिए बार बेंडिंग शेड्यूल कैसे तैयार किया जाए

एक कॉलम के लिए बार बेंडिंग शेड्यूल तैयार करना। कुछ मानदंड और धारणाएं हैं जिन्हें पूरा करने की आवश्यकता है आइए शुरू करें।

BBS (Bar Bending Schedule) Used by:-

निर्माण स्थल पर विभिन्न प्रकार के लोगों और अधिकारियों द्वारा बार बेंडिंग शेड्यूल का उपयोग किया जाता है जो नीचे दिया गया है:

  • Quantity surveyor
  • Steel fixer
  • Contractor
  • Project manager
  • Inspectors
  • Clerks of construction

निर्माण स्थल में सभी अनुमान और लागत संचालन मात्रा सर्वेक्षक की जिम्मेदारी है। बार बेंडिंग शेड्यूल स्टील के प्रकार, आकार और आकार का पता लगाने के लिए मात्रा सर्वेक्षक को विवरण देता है।

ठेकेदार निर्माण को आगे बढ़ाने के लिए स्टील बार का ऑर्डर देने के लिए बार बेंडिंग शेड्यूल (बीबीएस) का उपयोग कर रहे हैं।

स्टील फिक्सर अपना काम करने के लिए बार बेंडिंग शेड्यूल (बीबीएस) का उपयोग कर रहा है या बार बेंडिंग शेड्यूल (बीबीएस) के अनुसार कॉलम, बीम या स्लैब में बार को स्थापित कर रहा है कि कितनी कट लंबाई या बार के झुकने की आवश्यकता होगी और स्टील का कौन सा आकार होना चाहिए उपयोग हो।

निर्माण के निरीक्षक और क्लर्क बीबीएस को यह बनाने के लिए संदर्भित करते हैं कि क्षेत्र में सुदृढीकरण कार्य ड्राइंग के अनुसार डिजाइन सुदृढीकरण के साथ उचित है।

Details from the diagram:-

  • Thickness of slab is150 mm
  • Floor height is 3 m or 3000 mm
  • Footing depth is 400 mm
  • Development Length is 50d
  • Column has 4 numbers of 16 mm dia bars
  • Stirrup spacing is 8mm @ 150 mm C/C
  • Concrete Cover of Footing is 40 mm
  • Concrete Cover of slab is 20 mm

 

Steps for BBS of Column:-

आम तौर पर, कॉलम के बार बेंडिंग शेड्यूल तैयार करने के लिए पांच चरण होते हैं, इन पांचों का विवरण नीचे दिया गया है:

  • Find the length of Vertical Bar
  • Find out lapping
  • Cutting Length of Stirrups
  • Number of Stirrups
  • Bar Bending Schedule

Find the length of Vertical Bar:-

Length of Vertical bar = Development length (Ld) + footing depth + Floor Heights + Slab Thicknesses + Overlap Length

= (12×16) +400+ (3000) +(150) +(50×16)

= 4734 mm or 4.73 m

 

Find out lapping:-

length of lapping is 50d

Lapping length = 50 x Dia of steel

Length of lapping = 50×16 = 1000 mm.

हम जानते हैं कि स्टील की लंबाई 12.25 मीटर या 40 फीट लंबाई होती है

लंबवत बार की कुल लंबाई = 18.9 मीटर जो 12.25 मीटर या 40 फीट से अधिक हो, इसलिए लैपिंग प्रदान की जानी चाहिए।

Length of lapping is 1000 mm the result will be 18.928 + 1 = 19.928 m

यह इस लेख में पहले ही उल्लेख किया गया है, बार को लैप करते समय बिंदुओं पर विचार करें। कोई एक सही प्रक्रिया नहीं है जिसका हम उपयोग कर सकते हैं। बस लाइनें याद रखें।

  1. Don’t tie a column at bottom and also at top
  2. Lap at another bars every time
  3. Overlap top bars with bottom bars always

Cutting Length of Stirrups:-

we already discussed cut length of stirrup in Bar Bending schedule for beam article.

Length of One Hook = 9d

Cutting length of Stirrup = (Perimeter of stirrup – concrete cover) + Number of Hooks

Cut length of stirrup = 2(a- cc) + 2(b-cc) + 2 hooks

Cutting length of stirrup = 2(500- 25) + 2 (200-25) +(2x9d)

= (2×475) +(2×175) + (2×9×16)

Cutting length of Stirrup = 1588 mm

Number of Stirrups:-

No of stirrups = (Total length of Column ÷ spacing of stirrups) +1

Number of stirrups = 4773 ÷ 125 + 1

Number of stirrups = 39 numbers
