U-bolt, also known as saddle bolt, is a commonly used connecting fastener. Here is a detailed introduction to it:
1, Structural characteristics
The U-bolt consists of a screw with a U-shaped bend and two nuts, with threads on both ends that can be combined with the nuts.
• Simple structure, easy to install and disassemble.
2, Main advantages
Load balancing: The contact area between the screw and nut is relatively large, which can achieve load balancing, disperse forces, and improve the stability and seismic performance of the connection.
Easy installation: Simply thread the screw through the two objects to be connected and tighten the nut, without the need for additional washers or nuts, and without the need for excessive tools or equipment.
Material savings: The U-shaped bolts use relatively short screws, which can reduce the amount of material required and save costs.
Reusable: The installation and disassembly of U-bolts are relatively simple and can be reused, making them suitable for situations that require frequent disassembly and connection.
3, Application Fields
Vehicle manufacturing: such as cars, trucks, etc., U-bolts are used to fix and support pipelines.
Shipbuilding: used for fixing and connecting ship hulls and pipelines.
Bridge construction: used to fix and connect bridge structures and pipelines.
Metallurgical engineering: used to fix and support various pipelines and equipment.
Petrochemical industry: In the petroleum and chemical industry, U-bolts are used to secure and connect pipelines.
In the power industry, U-bolts are used to secure and support cables and pipelines in power facilities.
4, Usage and precautions
Before using U-bolts, it is necessary to drill holes on the fixing surface, then insert the U-bolts into the holes and tighten them.
Pay attention to keeping the surface of the product clean and dry, avoid contact with debris, and regularly clean rust or oil stains.
U-bolts should not be installed on rainy days, and the size and quality of the connecting components should be checked before installation.
In summary, U-bolts are widely used in various fields due to their unique structure and many advantages. When in use, it should be ensured that it is installed and maintained correctly to fully utilize its function.
