Embodiment Construction

[0023] The method for installing a modular flat roof on a railway passenger car includes: a roof frame 21, a middle roof, side roofs 3, 3', a first connector 61, a second connector 62, and a third connector 63. The roof frame 2 consists of two longitudinal Beams 21, 21', four crossbeams 22, 22', 22", 22"', the roof frame 2 has a trapezoidal groove 2-1 with the opening facing down, and the side roof 3 (the structure of the side roof 3' and the side roof 3 , the connection mode is the same, and in this example, only take the side top plate 3 as an example to illustrate) the wooden frame 3-2 at the longitudinal outer end, the wooden frame 11-1 at the first horizontal end 11 of the middle top plate 1 are respectively provided with slots 3-2- 1, 11-1-1, the upper part of the second connecting piece 62 and the third connecting piece 63 have wedges 62-1, 63-1 corresponding to the trapezoidal groove 2-1 of the roof frame 2, and the lower parts have wedges 62-1, 63-1 corresponding to th...

Abstract

The invention provides a method for installing a modular flat top plate of a railway passenger car. The method is characterized by firstly fixing a top plate framework on a steel structure of a car body; then installing side top plates at the two ends and fixing the side top plates on the top plate framework with connecting pieces; and finally installing a middle top plate and fixing the middle top plate on the top plate framework with the connecting pieces and compaction locks. The traditional flat top plate structures are assembled in a scattered manner, the scattered frameworks and linings are firstly installed and then the top plate is installed, thus needing abundant fasteners. Under the condition of the same constructors, the constructors spend 2 to 3 hours on assembling the flat top plate of each car in a scattered manner, but the constructors only spend about half an hour on modularly assembling the flat top plate of each car; therefore, the method has the following beneficial effects: the production efficiency is obviously improved; meanwhile, the installation quality and precision are higher; and the flat top plate is convenient to maintain and overhaul.

Description

technical field [0001] The invention relates to a method for installing a flat roof plate of a railway passenger car, and belongs to the technical field of interior installation 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 above-mentioned shortcomings of the prior art and provide a method for installing a modular flat roof of a railway passenger car, which has good installation quality...
