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.

电缆桥架安装过程中，用到的弯头一般有三种：一种是水平弯，一是垂直上下弯，还有一种是“之”字弯。以下举例说明这些弯头制作方法及公式：例：400×150的桥架做45°“之”字弯从桥架侧面取15cm×0.8在桥架底部画点将这段距离等分,然后三个点连接就成一个45°的等腰三角形(另一边用同一方法)，然后将这个三角切掉就形成一个45°弯，然后再用要做的高度×1.41为里边的顶点再画三角形，方向与前面那个相反，做出来就是一个45°之字弯。90°弯是取要做的那一面的2倍画三角，例如400×150做水平弯头,则取400×2画三角切掉就行了，如果要做垂直弯头则取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.

总结出来的公式：比如45度的坡度弯头，你只要记住这句话就知道怎么做了“爬坡45度，桥架高度乘以0.8中分划三条线为一个弯，斜边是爬坡高度乘以1.41，30度是桥架高度乘以0.8除以45乘以30中分划三条线为一个弯，斜边是爬坡高度乘以2水平90度弯是桥架宽度乘以0.8中分划线，斜边(内边)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 ".
