H-beam is an economical cross-sectional steel that is widely used in industry, construction, bridges, oil rigs and so on. H-beam is an economical sectional and efficient profile with more optimized cross-sectional area distribution and more reasonable strength-to-weight ratio. Since all parts of H-beam are arranged at right angles, H-beam has the advantages of strong bending ability, simple construction, cost savings and light structural weight in all directions.
H-shaped steel cutting using automatic gas cutting machine for steel plate cutting, opening bevel method for semi-automatic cutting K-type bevel, straightening correction after the completion of the unloading, in order to ensure the accuracy of the column plate assembly, need to prepare and assemble the fetal membrane, the assembly order is: first of all, the bottom plate as the benchmark, and then the mid-web plate and the upper wing plate, H-type assembly, welding, the column body welding using submerged arc automatic welding, after the completion of the welding straightening correction. H-shaped steel coating is strictly in accordance with the standard plate descaling brush oil, H-shaped steel production is completed by full-time quality inspectors for inspection numbering.
The application of H-beam is more environmentally friendly, and compared with concrete, dry construction can be used, which produces less noise and less dust. Due to the reduction of self-weight, the amount of soil taken from the foundation construction is small, the damage to land resources is small, and the amount of concrete used is greatly reduced, and the amount of excavated stone is reduced, which is conducive to the protection of the ecological environment. After the service life of the building structure expires, after the structure is demolished, the amount of solid waste generated is small, and the value of scrap steel resource recovery is high.
Then when installing high-frequency welded H-beam, first carry out product quality inspection of the high-frequency welded H-type steel prefabricated components themselves to ensure that the prefabricated components have no shortcomings, if there is a situation where the specifications and models do not meet, please immediately carry out disassembly, do not have to figure convenient. For the construction of the whole process to be applied to the measuring instrument to carry out correction, this is very critical, non-standard calibration will make the error more and more serious, the choice of special tools to be suitable on the line, without the pursuit of the level of perfect equipment. In the whole process of installation, it is inevitable that there will be a convergence deformation. Therefore, it is necessary to close the expected value in advance and formulate countermeasures to deal with it.
