With the rapid development of China's economy and the rapid increase in car ownership, the petrochemical industry is developing rapidly. As the direct image representative of major oil giants' sales companies, the number of gas stations has increased sharply. The gas station canopy is one of the main structures of gas stations. At present, the canopy generally adopts a steel grid structure. The steel grid structure is a spatial structure composed of multiple members connected by nodes in a predetermined grid form, which has the advantages of spatial stress, light weight, high stiffness, and good seismic resistance.
        The self weight of the grid structure is light, the amount of steel used is low, and it has a wide range of applications, suitable for both medium and large-span buildings. The basic units that make up a steel truss include triangular cones, triangular prisms, cubes, truncated quadrangular pyramids, etc. These basic units can be combined to form flat shapes such as triangles, quadrilaterals, hexagons, circles, or any other form. It has the advantages of spatial stress, light weight, high stiffness, and good seismic performance; It can be used as the roof of buildings such as sports halls, theaters, exhibition halls, waiting halls, sports stands, awnings, aircraft hangars, and two-way large column steel truss structures with distance from workshops.
        In the production and processing of gas station grid structures, the processing of grid structures and the welding process of steel frame structures are crucial. For the welding points of steel frame structures, quality and quantity must be guaranteed because they are the support plates of the steel structure grid, with large support, and can complete the supporting voltage distribution circuit of the steel structure grid, ensuring the solid and practical effect of the entire project.
