# 电缆桥架弯头就是解方程，学不好数学制作不出来

Cable tray elbow accessories are generally ordered in the factory, in the field to do the disadvantages of one is not beautiful, two is not durable (especially spraying and hot dip zinc treatment) , three is time-consuming, in particular, some project management is not allowed on-site processing, so usually users in advance according to the construction drawings out a good list, by the factory after the direct installation.

Because it is installed in the process, there are generally three kinds of elbow: a Horizontal Bend, a vertical up and down bend, and a “Zigzag”bend. Shandong Cable Bridge Su Xin told you to make the square cable bridge is actually the solution of the equation, not good math to make out.

EXAMPLE: 400X150 bridge with 45 ° Zigzag

Take 15 cm x 0.8 from the side of the bridge, draw a point under the bridge, equalize the distance, then connect the three points to form a 45 ° Isosceles Triangle (the other side) , then cut the triangle to form a 45 ° curve, then use the height you want to do X1.41 to draw another triangle for the innermost Vertex, and then use the height you want to do X1.41 to draw another triangle for the innermost vertex. If the angle of 90 ° is twice that of the triangle to be drawn, such as 400X150 for the horizontal elbow, then cut the 400X2 triangle into a triangle. If you want to make a vertical elbow, take 150X2.

Su Xin General Formula of Shandong Cable Bridge Frame: For example, Bend with 45 degree slope, you just have to remember the phrase, “Climb 45 degrees, Bridge Height Times 0.8 mid-line is a curve, ramp height times 1.41 degrees, ramp height times 0.8, ramp height times 1.41, ramp height times 1.41, ramp height times 0.8, ramp height times 0.8, ramp height times 0.8, ramp height times 1.41.
α值同“一”中角α值；本图的b值与 “一”中的b值不同，为层间距值。
The value of α is the same as the value of angle α in “One”, and the value of B in this figure is different from the value of B in “One”, which is the value of interval.

Making elbow of the first layer: The method of the two elbows of the first layer is the same as that of the elbows in "1". The distance a between the two elbows is determined on site, but the bend radius of the cable must be met. Make the second layer elbow: calculate the positioning size e of the first elbow of the second layer bridge: first measure the positioning size D value of the first layer bridge, then E = D BTG1/2 α : B is the layer spacing, and the Angle α value is the same as "one" in accordance with the method of "one" to make the first notch α of the second layer elbow; Calculate the spacing c value of two elbows: c=2btg1/2α In formula A: B is the spacing between layers, a is the spacing between two elbows of the bridge of the first layer. The second notch α of the second layer elbow is made according to the method of "one". Calculate the compensation size H: h=2 bTG1/2 α Fabricate the third layer elbow: fabricate the same method as the second layer elbow F = E bTG1/2 α g= 2BTG1/2 α C

You can’t really do it if the math is bad, but you can see here that it takes so many equations to make a bend, not to mention the whole bridge, can Imagine Shandong Cable Bridge Su Xin team is what kind of a group of people.
