[0002] U-bolts, also known as riding bolts, are non-standard parts. They are U-shaped, so they are also called U-bolts. They have threads on both ends for connection with nuts. U-bolts have a wide range of uses, mainly used in construction installation, mechanical parts connection, vehicles and ships, bridges, tunnels, railways, etc. The main shapes are semicircular, square, right angle, triangle, oblique triangle, etc.
[0003] An existing patent application, CN202221399230.6, discloses a high-temperature-resistant, deformation-resistant U-bolt. By combining a U-bolt, a surface reinforcement strip, a U-shaped reinforcement strip, a reinforcement block, a heat-resistant coating layer, a high-temperature wear-resistant coating layer, and a high-temperature corrosion-resistant coating layer, the U-bolt exhibits excellent high-temperature resistance and deformation resistance. However, the addition of reinforcement strips to the surface of the U-bolt does not effectively improve its strength. The U-bolt is prone to cracking when used for extended periods at high temperatures, hindering its usability.
