電纜橋架彎頭怎么做？有沒有公式？
電纜橋架各種彎頭配件一般都是在廠家預(yù)訂好的，在現(xiàn)場做的缺點(diǎn)一是不美觀，二是不耐用（特別是噴涂及熱浸鋅處理的），三是費(fèi)工時(shí)，特別是有的項(xiàng)目監(jiān)理是不允許在現(xiàn)場加工的，所以通常是用戶提前按施工圖紙出好清單，由廠家訂制好后再直接進(jìn)行安裝。
All kinds of elbow fittings of cable bridge frame are usually ordered by manufacturers. The shortcomings of on-site work are: one is not beautiful, the other is not durable (especially spraying and hot dipping), the third is time-consuming, especially some project supervision is not allowed to be processed on-site, so users usually make a list according to construction drawings in advance, and then install it directly after the manufacturer has made it.
電纜橋架安裝過程中，用到的彎頭一般有三種：一種是水平彎，一是垂直上下彎，還有一種是“之”字彎。以下舉例說明這些彎頭制作方法及公式：例：400×150的橋架做45°“之”字彎從橋架側(cè)面取15cm×0.8在橋架底部畫點(diǎn)將這段距離等分,然后三個(gè)點(diǎn)連接就成一個(gè)45°的等腰三角形(另一邊用同一方法)，然后將這個(gè)三角切掉就形成一個(gè)45°彎，然后再用要做的高度×1.41為里邊的頂點(diǎn)再畫三角形，方向與前面那個(gè)相反，做出來就是一個(gè)45°之字彎。90°彎是取要做的那一面的2倍畫三角，例如400×150做水平彎頭,則取400×2畫三角切掉就行了，如果要做垂直彎頭則取150×2。
There are generally three kinds of elbows used in the installation of cable bridge frames: one is horizontal bending, the other is vertical bending, and the other is zigzag bending. The following examples are given to illustrate the methods and formulas for making these elbows: for example, a 400 * 150 bridge is bent by 45 and a 15 cm 0.8 point is drawn from the side of the bridge to divide the distance at the bottom of the bridge. Then the three points are connected to form a 45 isosceles triangle (the other side uses the same method). Then the triangle is cut off to form a 45 bend, and the height to be done 1.41 is used The vertex of the edge is redrawn into a triangle in the opposite direction to the one in front, which is a 45 degree zigzag bend. A 90 degree bend is to draw a triangle twice as much as the side to be done. For example, a horizontal elbow of 400 *150 is to be made, and a triangle of 400 *2 is to be cut off. If a vertical elbow is to be made, a triangle of 150 *2 is to be cut off.
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(gè)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(gè)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”。
Summary of the formula: For example, 45 degrees of slope elbow, you only need to remember this sentence to know how to do it: "Climbing 45 degrees, bridge height multiplied by 0.8 divided into three lines as a bend, slope height multiplied by 1.41, 30 degrees is the bridge height multiplied by 0.8 multiplied by 45 times 30 divided into three lines as a bend, slope height multiplied by 2 levels of 90 degrees is the bridge width multiplied by 0.8." Medium dividing line, inclined edge (inner edge) more than 600 times 1.41 600 times 100 times 1.41 ".
