How to maintain H beam steel structure?
As a common structural steel material, H-shaped steel is widely used in construction, bridges, machinery manufacturing and other fields.
Maintenance methods of H section steel beam
First, check the appearance of the h shaped beam regularly. Check whether there is surface oxidation, rust, etc. If necessary, clean it in time and perform anti-rust treatment. When cleaning, you should use soft cloth, brushes and other tools, and do not use hard objects such as metal brushes to avoid scratching the surface and causing damage.
Secondly, keep the surface of the h shaped iron beam flat. Regularly check whether the cross-sectional dimensions of the h shaped steel beam are qualified. If there is distortion or bending, it should be repaired in time. It can be repaired by cold bending correction or hot temperature control correction to ensure that the geometric shape of the h type steel beam meets the specified requirements.
Thirdly, maintain the anti-corrosion performance of the h type beam. Select appropriate anti-corrosion coatings for coating according to the actual use environment to form a protective film and extend the service life of the material h beam. The surface treatment should be done before painting to ensure the adhesion and corrosion resistance of the coating.
In addition, the connection parts of the steel beam h should be checked regularly. For H-profile steel structures connected by bolts, the bolts should be checked for tightness and corrosion. If there is looseness or corrosion, it should be dealt with in time. For H-beam steel structures connected by welding, the welds should be checked for integrity. If there are cracks or fatigue, they should be repaired in time.
Finally, attention should be paid to the storage and transportation of H-beam profiles. When storing, H-beam steel should be placed in a dry and ventilated place to avoid direct sunlight and rain; collision and extrusion should be avoided during transportation, and the operating specifications should be followed when using lifting equipment to ensure that the H-beam steel is intact.
