Further, the container chassis 10 comprises a plurality of chassis stringer units. In the width direction of the container underframe 10, a plurality of underframe longitudinal beam unit underframe longitudinal beam units are arranged in parallel, that is, the length direction of the underframe longitudinal beam units is the same as the length direction of the container underframe 10, of course, the length direction of the underframe longitudinal beam units may be the same as the width direction of the container underframe 10, or the length direction of part of the underframe longitudinal beam units is arranged in the same direction as the width direction of the container underframe 10, and the length direction of the other part of underframe longitudinal beam units is arranged in the same direction as the length direction of the container underframe 10. So as to meet different arrangement requirements.
Referring to fig. 2, the bottom frame rail unit includes a horizontally disposed panel and a first folded edge extending downwardly from the panel, and a vertical height of at least one first folded edge of at least one bottom frame rail unit included in the container bottom frame 10 is not less than 80 mm. Therefore, the distance between the panel and the open end (namely the bottom end) of the first bending edge is not less than 80mm, and the requirements of container transportation and stacking are met.
The first bending edge and the panel can be integrally constructed or can be separately constructed and connected together, and the connection mode can comprise welding, splicing, bolt connection and the like.
Specifically, a first chassis longitudinal beam unit 11 configured in an L-shape in cross section is shown in fig. 2, and the first chassis longitudinal beam unit 11 includes a panel 110 and a first bent edge 111 provided at one end of the panel 110. The vertical height H1 of the at least one first folded edge 111 is not less than 80 mm.
It should be noted that the first bending edge 111 disposed at one end of the panel 110 is not necessarily a right angle connection with the panel 110, but may also be a T-shaped connection, in other words, the first bending edge 111 is not necessarily disposed at the edge of the panel 110, and may be disposed at a certain distance from the edge of the panel 110, so that the processing is more convenient. Furthermore, the first bending edge in the other embodiments described below is not necessarily provided at the edge of the panel.
Fig. 2 also shows a second underframe longitudinal beam unit 12 which is n-shaped in cross section, and the second underframe longitudinal beam unit 12 comprises a panel 120 and two first bending edges which are respectively arranged at two ends of the panel 120.
In the illustrated embodiment, the container chassis 10 comprises four first chassis longitudinal beam cells 11 and one second chassis longitudinal beam cell 12. Adjacent underframe stringer units may be connected by a fixed connection, such as a weld, or by a removable connection, such as a bolt connection.
In order to increase the strength of the first bending edge 111, thereby improving the strength of the entire first chassis longitudinal beam unit 11 and the strength of the container chassis 10, the open end (the end not connected to the panel 110) of the first bending edge 111 may be provided with a second bending edge 112, and the second bending edge 112 and the first bending edge 111 may be disposed at an angle. Further, the second bending side 112 may be disposed perpendicular to the first bending side 111. In this way, the second folded edge 112 may be substantially parallel to the panel 110, and may serve as a support.
The second bending edge 112 may be located on the same side of the first bending edge 111 as the panel 110, or may be located at two ends of the first bending edge 111, respectively, which is not limited in the present invention.
Turning to fig. 3. In the illustrated embodiment, the container chassis 10 includes one second chassis stringer unit 12. The panels 120 are sized approximately the same as the width of the container chassis 10 to cover the entire container chassis 10.
To increase the strength of the second chassis stringer unit 12, the lower surface of the panel 120 may also be provided with a stiffener 123, and the stiffener 123 may extend along the length of the chassis stringer unit.
Further, the vertical heights of the two first bending edges 121 of the second chassis side member cells 12 may be set to be the same or different. If the vertical heights H2 of the two first bending edges 121 are not the same, the vertical height H2 of the first bending edge, in which the vertical height is greater, is not less than 80 mm.
Turning now to fig. 4, a third underframe stringer unit 13 is shown, which is rectangular in cross-sectional configuration. The third chassis longitudinal beam unit 13 includes a panel 130, a bottom plate 132, and two first bending edges 131, and the two first bending edges 131 are respectively connected to respective corresponding ends of the panel 130 and the bottom plate 132. The bottom panel 132 may be configured substantially parallel to the panel 130, in which case the vertical heights H3 of the two first bending edges 131 may be substantially equal to each other, no less than 80 mm.
Alternatively, the third underframe stringer cell 13 may be a rectangular tube for ease of manufacture.
Further optionally, the thicknesses of the portions of the same rectangular tube and/or the thicknesses of the different rectangular tubes are different. That is, as shown in fig. 3, a thickened portion 133 may be provided on the same rectangular tube to increase the local strength; the thickness of the different rectangular tubes may also be arranged to be different, for example, the rectangular tubes near the sides or ends of the container floor may be arranged to be thickened.
