Title: How to make a horizontal bend in a bridge
Introduction:
The horizontal bending of the bridge is an important part of the electrical installation project. Correct operation can ensure the stability and aesthetics of the bridge. This article will combine the hot topics and hot content on the Internet in the past 10 days, introduce in detail the method of making horizontal bends of bridges, and provide structured data for reference.
1. Basic concepts of horizontal bending of bridges
Horizontal bending of the bridge refers to bending the bridge in the horizontal direction to adapt to the direction of the building structure or to avoid obstacles. Common types of horizontal bends include 30°, 45°, 90° and other angles.
| bending angle | Applicable scenarios | Things to note |
|---|---|---|
| 30° | Slightly adjust the direction | The bending radius should not be too small |
| 45° | Medium angle adjustment | Need to calculate cutting length |
| 90° | right angle turn | Need to use special elbow or make it on site |
2. Manufacturing steps for horizontal bending of bridges
The following are the specific steps for making a horizontal bend in a bridge:
1. Measurement and calculation
First, you need to measure the width and height of the bridge and calculate the cutting length based on the bending angle. Here are the calculation formulas for common angles:
| bending angle | Calculation formula |
|---|---|
| 30° | Cutting length = Tray height × 0.267 |
| 45° | Cutting length = Tray height × 0.414 |
| 90° | Cutting length = Tray height × 1.414 |
2. Cutting and bending
According to the calculation results, mark the cutting lines on the side panels of the bridge and use a cutting tool to cut. After cutting, bend the bridge to the desired angle and secure it with bolts.
3. Fixing and inspection
Secure the bent bridge to the bracket and check its stability and alignment. Make sure the bent parts are not deformed or loose.
3. Recommended popular tools and materials
According to the hot topics on the Internet in the past 10 days, the following are the tools and materials commonly used in the production of horizontal bends of bridges:
| Tools/Materials | Purpose | Popular brands |
|---|---|---|
| cutting machine | Cutting the bridge side panels | Bosch, Dongcheng |
| bending machine | Bent bridge | Jin Fangyuan, Yawei |
| Bolt | Fixed bridge | Jinyi, Ruida |
4. Frequently Asked Questions and Solutions
The following are common problems and solutions in the production of horizontal bends of bridges:
| question | Reason | solution |
|---|---|---|
| Incorrect bending angle | Calculation errors or cutting deviations | Remeasure and correct the cut line |
| Bridge deformation | Bending force is too large | Use a bending machine to assist operations |
| Not firmly fixed | Bolts not tightened | Check and tighten all bolts |
5. Safety precautions
When making horizontal bends of bridges, you need to pay attention to the following safety precautions:
1. Wear protective gloves and goggles to avoid injury while cutting.
2. Make sure the cutting machine and bending machine are in good condition to avoid equipment failure.
3. Keep the work area tidy to prevent tripping or slipping.
Conclusion:
The production of bridge horizontal bends requires precise calculations and skilled operating skills. Through the introduction of this article, I hope it can help you better complete the production of horizontal bends of bridges. If you need further information, you can refer to relevant engineering manuals or consult professionals.
