[0002] The traditional elevator car bottom is welded by profiles, but this welding method is time-consuming and labor-intensive, and it is easy to damage the galvanized layer on the surface of the profile, which will cause corrosion of the bottom after long-term use and poor stability. In view of the above defects, the current solution of manufacturers is to use riveting instead of welding to achieve splicing and fixing of profiles. Although this method can save the welding process of the elevator bottom, it is limited by the riveting process, which makes it only suitable for welded pipes with relatively low structural strength, and thus cannot use seamless steel pipes with higher structural strength to assemble the elevator bottom. As a result, the structural strength and stability of the elevator bottom are reduced.
