Abstract

The invention relates to the technical field of rail vehicle floors, and discloses a bonding process for rail vehicle floors, which includes the following steps: S1, cleaning, polishing, and re-cleaning the surface of the car body chassis; Calculate the installation thickness of the adjusting gasket based on the horizontal values ​​of multiple points on the surface of the frame; S3. Bond the adjusting gasket to determine the thickness of the glue; S4. Lay the floor after standardizing the glue, and use the floor pressing tool to fix the floor to prevent the floor from deforming ; S5. Finally, after the floor is fixed, dry it for a corresponding time under the specified environment. The invention has simple process and strong operability, and can effectively improve construction quality and work efficiency.

Description

technical field [0001] The invention relates to the technical field of rail vehicle floors, in particular to a bonding process for rail vehicle floors. Background technique [0002] For rail vehicles with bonding structure, the floor needs to be bonded to the underframe of the car body. At present, there are few bonding structures used in domestic rail vehicles, especially for floor bonding. There is no ready-made bonding process for reference. Due to the large floor area and special structure of the vehicle, the current general bonding process is adopted, the quality is not easy to control, and there is a hidden danger of poor bonding. Contents of the invention [0003] (1) Technical problems to be solved [0004] The purpose of the present invention is to provide a bonding process for rail vehicle floors, which can ensure the effect of bonding through thorough substrate treatment, precise leveling methods and reasonable fixing methods, so as to achieve firm bonding of t...
