The section of the H-section steel is similar to the uppercase letter H, also known as the universal steel beam. The cross section of the H-section steel usually comprises two parts, a web and a flange plate, also known as the waist and the side. H-beam specifications are many, the specific specifications are as follows:
After understanding the commonly used H-beam specifications, let's take a look at the construction of H-beam:
1.The first step in the production of H-shaped steel components is to stake out the material. If the processing quality of the components is not up to the requirements, the construction work will be affected, resulting in quality problems in the building. Therefore, the cutting of H-beam must be strictly followed. The drawings are carried out.
2. There are three main types of connection of H-shaped steel: one is welding of steel, the other is bolting, and the third is rivet connection. Among them, the main part of the production is welding, and the welding quality is related to the quality of the whole building. Professional welding personnel to complete the welding work, must be fully welded, not leaking.
3. The biggest feature of H-beam steel building is the assembly type. The components processed in the factory are directly transported to the construction site for installation. If there is a problem with the quality of the installation, not only will the quality of the entire project be greatly reduced, but it may also cause on-site construction accidents. Therefore, the installation process should follow the process steps to ensure the stable reinforcement of the H-beam project.
4. The fireproof and anticorrosive properties of H-shaped steel are general, so the coating of fireproof coating and anti-corrosion coating should be done when the component is processed. When coating, the thickness of the paint film is not uniform and the surface sag is avoided.
H-beams have relatively comprehensive specifications, and they have many advantages. They are widely used in various civil and industrial building structures; various large-span industrial plants and modern high-rise buildings, especially in areas with frequent seismic activities and high-temperature working conditions. Industrial plant; large bridges, heavy equipment, highways, ship skeletons, mine support, foundation treatment and dam engineering, various machine components with large bearing capacity, good section stability and large span.
