Abstract

The invention relates to the technical field of railway vehicle floors and discloses a gluing technique for railway vehicle floors. The gluing technique comprises the following steps: S1, the surface of a vehicle body underframe is cleaned, polished and cleaned again; S2, the level values of a plurality of points on the surface of the vehicle body underframe are measured by a measuring tool, and the mounting thickness of adjusting shims is calculated; S3, the adjusting shims are glued to determine the gluing thickness; S4, floors are paved after standard gluing and fixed by using a floor pressing tool to prevent the floors from deforming; and S5, finally, after the floors are fixed, the floors are dried for corresponding time in the specified environment. The gluing technique for the railway vehicle floors has the advantages that the technique is simple; the operability is strong; and the construction quality and the work efficiency are effectively improved.

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...
