如何制作桥架45度弯

There are generally three types of elbows used in the installation process of cable trays in Shandong: horizontal bending, vertical up and down bending, and "zigzag" bending. Without further ado, the following examples illustrate the methods and formulas for making these elbows:

Example: Make a 45 ° zigzag bend on the 400X150 cable tray.

Take 15cmX0.8 from the side of the bridge and draw a point at the bottom of the bridge to divide the distance equally, then connect the three points to form a 45 ° Isosceles triangle (the same method is used for the other side), then cut the triangle to form a 45 ° bend, and then draw a triangle with the height to be done X1.41 as the top of the inside, and the direction is opposite to the front one, so that it is a 45 ° zigzag bend. A 90 ° bend involves drawing a triangle twice the size of the side to be made. For example, if 400X150 is used as a horizontal bend, 400X2 is used to draw the triangle and cut it off. If a vertical bend is to be made, 150X2 is used.

The formula summarized by the bridge:

For example, for a 45 degree slope elbow, you only need to remember this sentence to know how to do it: "Climbing a 45 degree slope, multiplying the height of the bridge by 0.8, dividing the three lines into one bend. The slope is the climbing height multiplied by 1.4130 degrees, dividing the bridge height by 0.8, dividing it by 45, and dividing it by 30. The slope is the climbing height multiplied by 2. The horizontal 90 degree bend is the bridge width multiplied by 0.8, and the slope (inner edge) is 600 above 200 times 1.41600 below 100 times 1.41.

Production method and steps
1、制作层弯头：
1. Make the first layer of elbow:

The practice of the two elbows on the first layer is the same as that of the elbow in "1". The distance between the two elbows, a, is determined on site, but it must meet the requirements of the cable bending radius.
2、制作第二层弯头：
2. Make the second layer elbow:
（1）计算第二层桥架个弯头的定位尺寸e：
(1) Calculate the positioning dimension e of the first elbow of the second layer bridge:

First measure the positioning dimension d of the first layer bridge, then e=d+btg1/2 α

In the formula: b is the interlayer spacing, and the angle α The value is the same as the middle corner of 'one' α value
（2）依照“一”的方法制作第二层弯头的第1个切口α；
(2) Make the first cut of the second layer of elbow according to the "one" method α；
（3）计算两个弯头间距c值：c=2btg1/2α+a式中：b为层间距，a为层桥架两个弯头的间距
(3) Calculate the distance c between two elbows: c=2btg1/2 α+ In formula a, b is the interlayer spacing, and a is the spacing between the two elbows of the first layer of bridge
（4）依照“一”的方法制作第二层弯头的第2个切口α；
(4) Make the second cut of the second layer of elbow according to the method of "one" α；
（5）计算补偿尺寸h：h=2btg1/2α
(5) Calculate compensation size h: h=2btg1/2 α
3、制作第三层弯头：
3. Make the third layer elbow:

The production method is the same as the second layer elbow
f=e+btg1/2αg=2btg1/2α+c
F=e+btg1/2 α G=2btg1/2 α+ C

Note: The production method for any angle bend of multi column equally spaced and equally wide bridge is the same as that for any angle bend of multi-layer equally spaced and equally high bridge.

3、 The practice of multi-layer "zigzag" bends:

Similar to 'two', except that the values of a, c, and g are equal, and the two tangent α Corner on both sides of the bridge

That's all for the related content of making a 45 degree bend in the bridge. I hope it can be helpful to you. For more information, please come to our website http://sfcyhotel.com Consult and understand!
