Abstract

The invention discloses a modular flat top plate of a railway passenger car, comprising a top plate framework, an intermediate top plate and side top plates, wherein the top plate framework comprises two longitudinal beams and four cross beams and is fixedly connected with a steel structure of a car body; longitudinal inner and outer ends of the side top plates are respectively connected with the cross beams of the top plate framework through a first connecting piece and a second connecting piece; the first transverse end of the intermediate top plate is fixed with a first longitudinal beam of the top plate framework through a third connecting piece; and the second transverse end of the intermediate top plate is fixed with a second longitudinal beam of the top plate framework through a compressing lock. The modular flat top plate can be assembled by the following steps of: firstly, fixing the top plate framework on the steel structure of the car body by attachment lugs; secondly, mounting side top plates at two ends and fixing the side top plates on the top plate framework by the connecting pieces; and finally, mounting the intermediate top plate and fixing the intermediate top plate on the top plate framework through the connecting pieces and the compressing lock. By adopting the modular flat plate structure, each car can be assembled by modules in about half an hour, thus the production efficiency is remarkably improved; meanwhile, the modular flat top plate has higher mounting quality and mounting precision and is convenient for maintenance and overhaul.

Description

technical field [0001] The invention relates to a flat roof plate structure of a railway passenger car, and belongs to the technical field of interior decoration of railway passenger cars. Background technique [0002] The interior decoration of a bus is the main part that directly meets the passengers. Its design technology continues to develop with the development of vehicle technology. The structural shape of the flat roof is directly related to the overall aesthetic effect of the car. In the past, the flat roof structure of railway passenger cars was in the form of bulk assembly, the construction was cumbersome, the production site was messy, and the assembly efficiency was low. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the disadvantage of low assembly efficiency of the existing scattered structure flat roof, and provide a modular flat roof for railway passenger cars with high assembly efficiency.
