Stereoscopic parking garages are no longer unfamiliar to everyone, as many cities have begun to adopt this type of "car building" to solve the problem of insufficient parking spaces and difficult parking. Due to the fact that the main body of the three-dimensional parking garage is a metal structure, the technical structure has good support and bearing capacity due to its high strength during use. Therefore, the management personnel of the three-dimensional parking garage should adopt the correct methods to regularly maintain and repair the metal structure to ensure that it meets the following requirements.
1. The three-dimensional parking garage company should inspect and maintain the firmness, stability, and reliability of the local and overall connections of the metal structure to ensure that there are no permanent distortions or weld cracks in the metal structure, and that there is no obvious deformation or abnormal noise during loading and operation.
2. The high-strength bolts in the three-dimensional parking garage should be regularly inspected and tightened to meet the specified tightening torque requirements. Fastener flat washers and spring washers should be complete, and any defects found should be immediately repaired. The bolt length should be higher than the nut to ensure reliable fastening and no looseness.
3. Due to the requirements for the verticality of the columns, parallelism between beams, and length difference between the two diagonal lines of the metal structure frame in a three-dimensional parking garage, these aspects should be checked during daily use. If any deviation is found, it should be corrected in a timely manner. In addition, the handling trolley of the three-dimensional parking garage needs to bear a certain load, so the deflection of the midpoint of its longitudinal main beam must meet the requirements.
4. The embedded bolts of the column bottom plate of the three-dimensional parking garage should not be loose or corroded. The straightness of the guide rail should be maintained well, without permanent deformation, and the joints should be uniform and flat without obvious convex or concave points.
Due to the fact that the metal structure is the main component of the three-dimensional parking garage and plays an important role in the access, parking, and lifting of cars, it is not only necessary to ensure that the installation meets the requirements, but also to regularly inspect and maintain it after it is put into use to ensure that the metal structure of the three-dimensional parking garage always meets the requirements.
