Methods and techniques of adding layers to steel structures

Steel structure companies generally use I-beam and channel steel for the main girder of the steel structure for the interlayer, and square tube or angle steel for the auxiliary beam. From the perspective of the same cross-sectional area of ​​the steel, its flexural strength decreases in order of H-beam, I-beam, channel steel. The H-beam I mentioned here may be unfamiliar to some people, but it is an economical type of steel recommended for construction projects. Those who are unfamiliar can check the relevant information or learn from those in the industry. The method of adding layers to the steel structure is nothing more than to weld the section steel that meets the specifications into a criss-cross frame structure, and lay wooden boards or make a composite floor. The important thing here is the reliability of the steel structure. It not only relies on the welding quality of the section steel, but also There is also the selection of the flexural resistance of the main beam, but more importantly, it relies on the reasonable connection method between the steel structure and the wall. Therefore, it is not as simple as imagined to add layers of steel structures, and it is necessary to invite troops with planning and construction qualifications to do it. In the construction process of steel structure engineering, attention should be paid to adjusting errors, determining the orientation of the stair facade, the welding seam should be plump and strong, and the welding quality should meet the specifications. In addition, the steel structure has electrical conductivity, and special attention should be paid to the lightning protection method to ensure the construction.
