Gao Bang bridge
Angle between alpha bridge and plane climbing.
Just substitute 90 degrees and 45 degrees.
Take 15cmX0.8 from the side of the bridge, draw points at the bottom of the bridge for equal distance, then connect the three points to form a 45 isosceles triangle (the other side uses the same method), then cut off the triangle to form a 45-degree bend, and draw a triangle with the height of X 1.4 1 as the innermost vertex.
A 90-degree bend is to draw a triangle, which is twice the side to be made. For example, make a cross elbow with 400X 150, draw a triangle with 400X2, and cut it off. If you want to make vertical elbows, use 150X2. Remember that the sideline is against the midline, and the midline is against the sideline.
Extended data:
Main components of cable tray:
When the cable tray is installed, it is supported by the upright post and the support arm. The column is the main component to support the cable bridge; The load of the bridge is transferred to the column through the support arm. Therefore, the strut and bracket are the two main components of cable tray installation.
1. When the cable tray enters the building from outside, its slope should not be less than1100.
2. When the cable tray crosses the electrical equipment, its clear distance shall not be less than 0.5m.
3. When two groups of cable trays are laid in parallel at the same height, the clear distance should not be less than 0.6m.
4. Draw the route of the bridge on the parallel diagram, and indicate the coordinates or positioning dimensions and elevation of the starting point, ending point, turning point, branch point and lifting point of the bridge. If the side view of the bridge laying axis can be drawn, the material statistics will be more accurate.
