The upright posts and the compartment plate 24 are assembled to complete the assembly of the front wall assembly 2 and the rear wall assembly 3.

And assembling the side frame and the side wall plate 45 to complete the assembling of the side wall assembly 4.

And S2, positioning the bottom plate assembly 1.

The floor assembly 1 is placed in the operating position and the position thereof is properly adjusted, thereby completing the positioning of the floor assembly 1.

And S3, installing the front wall assembly 2 and the rear wall assembly 3.

The bottom of the front wall component 2 is positioned with the transverse connecting surface of the bottom plate component 1, and the bottom of the front wall component 2 is connected with the transverse connecting surface through bolts.

The bottom of the rear wall component 3 is positioned with the transverse connecting surface of the bottom plate component 1, and the bottom of the rear wall component 3 is connected with the transverse connecting surface through bolts.

And S4, installing the two side wall assemblies 4.

The lap joint surfaces of the two stand columns of the side wall component 4 are respectively positioned with the front wall component 2 and the rear wall component 3 and are connected in a riveting mode. And the contact surfaces of the lap joint surfaces and the front wall component 2 and the rear wall component 3 are coated with structural adhesive, so that the connection strength is further increased.

Meanwhile, the bottom of the side wall assembly 4 is positioned with the longitudinal lapping surface 1128 of the bottom plate assembly 1 and is riveted. And the contact surface of the longitudinal lapping surface 1128 and the side wall component 4 is coated with structural adhesive, so that the connection strength is further increased.

In addition, the corner fittings 6 are pre-installed on the tops of the front wall assembly 2 and the rear wall assembly 3 in advance, after the side wall assemblies 4 are positioned with the front wall assembly 2 and the rear wall assembly 3, holes are drilled and riveted on the corner fittings 6 on site according to the upper edge beams of the side wall assemblies 4 with the holes being pre-drilled as positioning references, and the corner fittings 6 are installed and fixed.

And S5, mounting the top plate assembly 5.

Through steps S1 to S4, the bottom plate assembly 1, the front wall assembly 2, the rear wall assembly 3, and the two side wall assemblies 4 are enclosed to form a box-shaped structure with an open top. The box-like combination has stable structure.

When the top plate assembly 5 is installed, the cross beam 52 is firstly lapped on the support 422 of the side wall assembly 4, and the cross beam 52 is riveted with the support 422. Then, the whole top plate 51 is laid, and the bead 53 is pressed against the edge of the top plate 51 and is riveted.

And finally, sealing and bonding are carried out at the connecting position to finish the installation of the top plate 51, and finally the compartment combination is realized.

The car combining method is performed according to a certain assembly process sequence, but actual car assembly is not limited to the assembly process sequence, and the car can be assembled in a connection mode between modules in the application.

The assembly method, i.e., the carriage combining method, of the carriage body 800 in this embodiment is simple to operate.

Meanwhile, through the structural design, the tops of the front wall assembly, the rear wall assembly and the two side wall assemblies are made to be stable structures for supporting the top plate, and the design that the traditional compartment body top plate is provided with a complete frame is omitted, so that the weight of the top plate assembly is greatly reduced, and the light weight of the compartment body is further realized. And the roof adopts the flexible assembly of rivet, has effectively reduced the roof that the railway carriage or compartment body brought because the rigidity of top is too high and has connected the risk of losing efficacy or roof fracture.
