Description

Container bottom structure and container

Technical Field

The utility model relates to a container bottom structure and container.

Background

Containers have become widely used as freight transport means, and the underframe and the floor of the container jointly constitute the load-bearing structure of the goods in the container.

Referring to fig. 1A to 1C, for a 20' container, the bottom frame 20 includes two bottom side beams 21 and a plurality of bottom cross beams 22 connecting the two bottom side beams 21 together, and two floor boards 10 of S1 × E1, i.e., two floor boards 10 of 1010mm × 1160mm, and four floor boards 11 of S2 × E1, i.e., four floor boards 11 of 2400mm × 1160mm, need to be laid on the bottom frame 20 when being installed, so that four floor joints exist between the floor boards 11 and between the floor boards 10 and 11. In the using process of the container, the floor joint is stressed seriously and is easy to damage, in order to improve the strength of the floor joint, a wide bottom cross beam 23 is required to be arranged at the floor joint, and the width of an upper wing plate of the wide bottom cross beam 23 is larger than that of an upper wing plate of the bottom cross beam 22. However, the ISO trolley test shows that the risk of exceeding the standard of permanent deformation still exists due to the serious stress of the wide bottom cross beam 23. In order to further improve the bearing capacity of the wide-bottom beam, reinforcing ribs 231 are additionally arranged between the wing plates of the wide-bottom beam 23 if necessary. The welding of strengthening rib is comparatively complicated, has also increased the quantity of material when having increased the degree of difficulty of manufacturing the installation.

Referring to fig. 2A-2C, for a 40' container having a gooseneck tunnel structure, the undercarriage 20 further includes a short bottom rail 24 disposed between the gooseneck tunnel structure 40 and the bottom side rail 21, the short bottom rail 24 having a length less than the length of the bottom rail 22. During installation, six S2 × E1 floor boards 11, namely six 2400mm × 1160mm floor boards 11, two S3 × E1 floor boards 13, namely two 1388mm × 1160mm floor boards 13, and four S4 × E2 floor boards 30, namely four 1626mmX636mm floor boards 30, which are positioned on two sides of the goose panel 41 are paved on the underframe 20. Thus eight floor joints are present between the floor panels 11, between the floor panels 11 and 12 and between the floor panels 30. Also, in order to improve the strength of the floor joint, it is necessary to provide wide bottom cross members 23 at the joints between the floor panels 11 and 12, and short wide bottom cross members 25 at the joints between the floor panels 30. If necessary, reinforcing ribs 231 are additionally provided between the flanges 232 of the wide-bottomed cross member 23.

It follows that for dry cargo containers, there are four specifications for conventional flooring laid on the container chassis. The floor has more specifications, and on one hand, the floor needs to occupy larger stock during stock preparation; on the other hand, the floor installation process is complicated and there are many floor joints. Because the floor joint is stressed seriously and is easy to damage in the using process of the container, a wide bottom beam and a short and wide bottom beam are required to be arranged at the floor joint to improve the strength of the floor joint, improve the bearing capacity of the container underframe and prolong the service life of the container; if necessary, reinforcing ribs are additionally arranged between wing plates of the wide-bottom cross beam so as to further improve the bearing capacity of the wide-bottom cross beam; however, the complexity of welding the reinforcing bars increases the difficulty of manufacturing and installation, and the addition of the reinforcing bars also increases the amount of material used.

To this end, there is a need to provide a container bottom structure and a container that at least partially solves the above problems.
