Problems solved by technology

The side wall frame of this structure needs more welding, and the deformation caused by welding will make it difficult to guarantee the flatness of the side wall, which will affect the appearance quality of the car body, which is increasingly valued by customers. The structure becomes complicated, and welding requires manpower and time investment, which increases manufacturing costs, reduces production efficiency, and also leads to a corresponding increase in the weight of the car body

Embodiment 1

[0031] Such as figure 1 , 2 , 3 and 4 show a new type of stainless steel side wall structure, including a side wall frame 1 and a side wall panel 2. The side wall panel 2 is formed by laser blanking and then laser welding in consideration of the size of the panel, and the mechanization efficiency is high. , the shape is beautiful; the exterior of the side wall frame 1 is welded with side wall panels 2, and a plurality of window frames 11 and door frames 12 are provided in the side wall frame 1, and the side wall panels 2 are provided with window frames 11 1. The opening corresponding to the door frame 12. The side wall skeleton 1 is connected by a plurality of horizontally arranged beams 3 and a plurality of longitudinally arranged columns 4. The left and right sides of the frame 1 are respectively provided with end columns 43, the left and right sides of the door frame 12 are respectively provided with door columns 42, a window upper beam 31 is arranged above the window fram...

Embodiment 2

[0034] Such as figure 1 As shown, the side wall skeleton includes a first skeleton wall 111 with a single window frame 11 and a second skeleton wall 112 with two adjacent window frames 11, and there are two first skeleton walls 111, which are respectively installed At the left and right ends of the side wall frame 1, there are multiple second frame walls 112 installed between the two first frame walls 111, and between the first frame walls 111 and the second frame walls 112 there are A door frame 12 is provided between the plurality of second skeleton walls 112 .

[0035] Such as figure 1 and Figure 5 As shown, two window columns 44 are arranged between the two window frames 11 in the second skeleton wall 112, and the two window columns 44 pass through the window upper beam 31 and the window lower beam. 311, corresponding card slots 9 are respectively set on the connection positions between the window column 44 and the window upper beam 31 and the window lower beam 311, an...

Embodiment 3

[0039] Such as Figure 6 As shown, the lower beam 311 under the window, the upper beam 31, the beam 34 between the windows, the column 44 between the windows, the column 41 on the window and the column under the window are Z-shaped steel profiles, and the waist beam 32 and the door column 42 are several Shaped steel profile, the end column 43 is a profile made of a several-shaped steel and an L-shaped steel connected to the side of the several-shaped steel, the flat plate of the L-shaped steel is flush with the protrusion of the several-shaped steel, so Described lower crossbeam 33 is by a circular arc-shaped arc plate 5, and the side portion of arc plate 5 is connected with the section material that side plate 7 is formed, and the structure of arc plate 5 of described lower crossbeam 33 in the present invention has strong compression resistance. Advantages, under the condition of satisfying the strength and rigidity of the car body, less materials are used and the weight is l...

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...
