Referring to fig. 10, 10a and 10b, fig. 10, 10a and 10b are each a schematic view of an embodiment of a bottom cross member in a container of the present invention. In contrast to the aforementioned exemplary embodiments shown in fig. 7, 7a, 7b, 7c and 7d, the bottom beam connectors 122 of the bottom beam 12 are disposed at the ends of the bottom beam body 121, such as extending integrally therefrom, and do not extend beyond the ends of the body 121; in the embodiment illustrated in fig. 10, 10a and 10b, the bottom side rail connector 122 of the bottom rail 12 is disposed at the end of the bottom rail body 121, such as by welding, and extends outwardly therefrom.

Referring to fig. 10, the bottom side beam connector 122 is C-shaped having a web and two wings.

Referring to fig. 11, fig. 11 is a flow chart illustrating a method of assembling the container shown in fig. 3. The invention provides a combined final assembly method of a container, which substantially comprises the following steps:

s1101, a sidewall assembly 3 is connected to one end of the bottom beams 12.

And S1102, connecting the other side wall assembly 2 with the other ends of the bottom cross beams 12 to obtain a frame.

S1103, welding the front wall assembly 5 to the front ends of the two side wall assemblies 2, 3.

And S1104, welding the door end assembly 6 to the rear ends of the two side wall assemblies 2 and 3.

And S1105, welding the top plate assembly 4 and the door lintel 62 in the door end assembly 6, the top side beams in the two side wall assemblies 2 and 3 and the front upper beam 52 in the front wall assembly 5 together.

It will be appreciated that, in contrast to the bottom cross member 12a of the conventional structure shown in fig. 2, the present invention proposes a new bottom cross member 12, and the new bottom cross member 12 is a combined structure, one part of which (i.e., the bottom cross member main body 121) corresponds to the bottom cross member 12a of the transmission, and the other part of which (i.e., the bottom side member connecting member 122) is connected between the bottom cross member main body 121 and the

bottom side members

21, 31, and the shapes of the two parts are adapted, and the shape of the bottom side member connecting member 122 is adapted to the shapes of the

bottom side members

21, 31. By means of the set constraint guarantee of the adaptive shapes, the stress of the fastening piece 9 can be effectively reduced, and therefore the beneficial effects of good connection strength, good sealing performance of the connection part and the like are achieved. In this way, the bottom cross member 12 and the side wall assemblies 2 and 3 can be assembled without using the conventional welding connection, and the bottom cross member 12 and the

bottom side members

21 and 31 can be aligned and then connected together by the fasteners 9. In other words, with the new bottom cross member 12 structure, the connection manner of the

bottom side members

21, 31 on the side wall assemblies 2, 3 of the container 10 and the bottom cross member 12 can be changed from the conventional welding to the fastening.

It is worth mentioning that the structure that the bottom cross beam 12 is connected with the bottom side beams 21 and 31 by the fasteners 9 is easy to operate and has no sealing and rust-proof problems because all connecting surfaces are positioned at the bottom of the container 10. In addition, the main welding of the container 10 is completed in a component manufacturing site, which can effectively reduce the workload of completing the container assembly in different places. The welding seam during final assembly is mainly at the corner fitting, and subsequent treatment basically does not need sanding and other treatment, and final assembly can be carried out with a paint surface. Since the bottom beam 12 is an important load-bearing structure of the container 10, the new structure of the bottom beam 12 can well meet the application requirements of the container for assembly in different places.

Compared with the prior art, the container 10 of the invention has the advantages that the bottom cross beam 12 of the container 10 is skillfully designed into two parts, namely the bottom cross beam main body 121 and the bottom side beam connecting piece 122 arranged at the end of the bottom cross beam main body 121, and the bottom side beams 21 and 31 are connected with the bottom cross beam main body 121 by the bottom side beam connecting piece 122, so that short welding seams are reserved for the general assembly in different places, and long welding seams are basically completed in the part manufacturing process; during the assembly in different places, only local welding is needed, so that the sanding and coating areas are greatly reduced, and the application requirements of assembly in different places can be well met.

It should be noted that in the above embodiment, the bottom side beams 31 and the corresponding bottom cross beams 12 are connected by the fasteners 9 penetrating through the bottom side beam connecting members 122. To install the fasteners 9, the bottom side rails 31, the corresponding bottom cross rail bodies 121, and/or the bottom side rail connectors 122 are provided with securing holes. These fastening holes can be either pre-set at the site of manufacture of the components or drilled at the site of assembly of the container. In the above embodiments, the fastening member 9 is a rivet, and in other embodiments, the fastening member 9 may be a bolt and nut combination.

In other embodiments, the bottom side beams 31 and the corresponding bottom cross beams 12 may also be welded. In other embodiments, the bottom side beams 31 and the corresponding bottom cross beams 12 may be bonded. It is to be understood that the bottom side member 31 and the corresponding bottom cross member 12 may be connected by at least one of welding, bonding, and fastening, in other words, the bottom side member 31 and the corresponding bottom cross member 12 may be connected by any combination of three types of connection of welding, bonding, and fastening.

In addition, although in the above embodiments, the bottom side member connecting member 122 is alternatively provided on the bottom side member 31 or the bottom cross member main body 121 to connect the bottom side member 31 and the bottom cross member main body 121; in another embodiment, the bottom side member connecting member 122 may be provided on both the bottom side member 31 and the bottom cross member body 121 to connect the bottom side member 31 and the bottom cross member body 121. Although in the above embodiment, two ends of the bottom beam main body 121 are respectively provided with two bottom beam connecting pieces 122 with the same structure; in other embodiments, the two bottom side beam connectors 122 may also be different in structure, such as: one of them adopts the structure illustrated in fig. 10, 10a or 10b, and the other adopts the structure illustrated in fig. 7, 7a, 7b, 7c or 7 d.
