Problems solved by technology

In the past, the connection between the flat roof, the partition wall, and the flat roof was made of back wood lining or aluminum beams, and wood screws were placed directly on the surface. In order to cover the screws, pressure strips were used to cover the outside, which was unsightly and caused material waste; and The installation method of this structure is simple, the quality is low, and it is not convenient for the maintenance and replacement of the flat roof

Abstract

A large-span flat top plate installation structure of a railway vehicle comprises a beam, a flat top plate framework, a flat top plate and a central flat top plate framework support which are fixed together through first connection pieces. The outer end of a first flat top plate is fixed with a first plat top plate framework through a second connection piece, the inner end of the first flat top plate is fixed with the central flat top plate framework support through a first press lock, and the outer end of the second flat top plate is fixed with a second flat top plate framework through a second press lock. The flat top plate structure omits lining materials on the back portion of the installation position of the prior structure, the periphery of the flat top plate is respectively fixed through the press locks in insertion mode, and the installation structure is attractive and generous in appearance due to the fact that no screws or press strips are exposed to the outside. Further, the installation structure is simple in structure and simple to assemble, and facilitates maintenance and replacement of the flat top plate. The connection position of the flat top plate and the connection piece is respectively provided with an adjusting rubber block and a press rubber block, has damping effect and is especially suitable for installation of the large-span flat top plate.

Description

technical field [0001] The invention relates to a rail vehicle long-span flat roof installation structure, which belongs to the technical field of rail vehicle interior decoration. Background technique [0002] The interior decoration of a passenger car is the main part that directly meets the passengers. Its design technology continues to develop with the development of vehicle technology, and its structural shape is directly related to the overall aesthetic effect of the car. In the past, the connection between the flat roof, the partition wall, and the flat roof was made of back wood lining or aluminum beams, and wood screws were placed directly on the surface. In order to cover the screws, pressure strips were used to cover the outside, which was unsightly and caused material waste; and The installation method of this structure is simple, the quality is low, and it is not convenient for the maintenance and replacement of the flat roof.
