style="text-indent:25px">從橋架側(cè)面取15cmX0.8在橋架底部畫點將這段距離等分,然后三個點連接就成一個45°的等腰三角形 (另一邊用同一方法)，然后將這個三角切掉就形成一個45°彎，然后再用要做的高度X1.41為**里邊的頂點再畫三角形，方向與前面那個相反，做出來就是一個45°之字彎。90°彎是取要做的那一面的2倍畫三角，例如400X150做水平彎頭,則取400X2畫三角切掉就行了，如果要做垂直彎頭則取150X2。橋架總結(jié)出來的公式：比如45度的坡度彎頭，你只要記住這句話就知道怎么做了“爬坡45 度，橋架高度乘以0.8中分劃三條線為一個彎，斜邊是爬坡高度乘以1.41 30度是橋架高度乘以0.8除以45乘以30中分劃三條線為一個彎，斜邊是爬坡高度乘以2 水平90度彎是橋架寬度乘以0.8中分劃線，斜邊(內(nèi)邊)600以上200乘以1.41 600以下100乘以1.41”。成都橋架批發(fā)</p><div style="width:100%;text-align:
