♥公式表示
计算外箍的长度：l=2×(b−2×c+h−2×c)+2×(w×d)−(3×t)×d
计算内箍1的长度，设b1为201：l=2×(b1+h−2×c)+2×(w×d)−(3×t)×d
计算内箍2的长度，设h1为147：l=2×(b−2×c+h1)+2×(w×d)−(3×t)×d
计算单肢箍的长度：l=(b−2×c)+2×(w×d)
♣计算步骤
计算外箍的长度：
= 2×(400−2×20+500−2×20)+2×(13.57×10)−(3×2.29)×10
= 2×(400−40.00+500−40.00)+2×(13.57×10)−(3×2.29)×10
= 2×(360.00+460.00)+2×(13.57×10)−(3×2.29)×10
= 2×820.00+2×135.70−6.87×10
= 1640.00+271−69
= 1911.00−69
= 1842.00㎜
计算内箍1的长度，设b1为201：
= 2×(201+500−2×20)+2×(13.57×10)−(3×2.29)×10
= 2×(201+460.00)+2×(13.57×10)−(3×2.29)×10
= 2×661.00+2×135.70−6.87×10
= 1322.00+271−69
= 1593.00−69
= 1524.00㎜
计算内箍2的长度，设h1为147：
= 2×(400−2×20+147)+2×(13.57×10)−(3×2.29)×10
= 2×(360.00+147)+2×(13.57×10)−(3×2.29)×10
= 2×507.00+2×135.70−6.87×10
= 1014.00+271−69
= 1285.00−69
= 1216.00㎜
计算单肢箍的长度：
= (400−2×20)+2×(13.57×10)
= (400−40.00)+2×(13.57×10)
= 360.00+2×2×360.00
= 360.00+271
= 631.00㎜
♦公式说明
外箍的长度 = 2 ×( 宽度 − 2 × 保护层厚度 + 高度 − 2 × 保护层厚度 )+ 2 ×( 弯折 × 箍筋直径 )−( 3 × 弯曲调整 )× 箍筋直径
内箍1的长度 = 2 ×( 宽度1 + 高度 − 2 × 保护层厚度 )+ 2 ×( 弯折 × 箍筋直径 )−( 3 × 弯曲调整 )× 箍筋直径
内箍2的长度 = 2 ×( 宽度 − 2 × 保护层厚度 + 高度1 )+ 2 ×( 弯折 × 箍筋直径 )−( 3 × 弯曲调整 )× 箍筋直径
单肢箍的长度 =( 宽度 − 2 × 保护层厚度 )+ 2 ×( 弯折 × 箍筋直径 )
