Novel stainless steel side wall structure and mounting method of novel stainless steel side wall

Abstract

The invention provides a novel stainless steel side wall structure and a mounting method of a novel stainless steel side wall. The novel stainless steel side wall structure comprises a side wall skeleton. The side wall skeleton is formed by connecting a plurality of cross beams and a plurality of vertical columns in a mutually-crossing mode, and the cross beams and the vertical columns are fixed through mutual inserting; end vertical columns are arranged on the left and right sides of the side wall skeleton correspondingly; door vertical columns are arranged on the left and right sides of doorframes correspondingly; a window upper cross beam is arranged on the upper portion of each window frame, and a window lower cross beam is arranged on the lower portion of each window frame; a waist cross beam is arranged below each window lower cross beam; three lower cross beams are arranged below each waist cross beam; a window upper vertical column is connected to each window upper cross beam;skeleton connecting plates are welded inside the connecting positions of the window upper cross beams and the window upper vertical columns in the side wall skeleton; window lower vertical columns are connected among each window lower cross beam, the corresponding waist cross beam and the three corresponding lower cross beams; and skeleton connecting plates are welded inside the connecting positions of the window lower cross beams and the window lower vertical columns in the side wall skeleton. The cross beams and the vertical columns of the novel stainless steel side wall structure are fixedthrough mutual inserting connection, the deformation problem caused by welding of a skeleton is solved, the production cost is saved, and the assembly production efficiency is improved.

Description

technical field

[0001] The invention relates to a novel stainless steel side wall structure and a method for installing the novel stainless steel side wall, and belongs to the field of urban rail transit vehicle body design. Background technique

[0002] The side wall structure of stainless steel subway vehicles mainly includes side wall skeletons, window frames, door frames, and side wall panels. The traditional design and assembly process of side walls of stainless steel subway vehicles is as follows: determine the arrangement and connection methods of beams and columns according to design requirements, and then The beams and columns are welded to form the side wall framework. Secondly, the side wall framework, window frames, and door frames are connected with the side wall panels by resistance spot welding, which is what we commonly call "skin". Finally, the entire side wall is assembled. The side wall frame of this structure needs more welding, and the deformation caused...
