Background
Fig. 1 to 3 are schematic cross-sectional views showing an assembly of a chassis 10 and a floor 20 of a container of the related art.
As shown in fig. 1 to 3, the container of the prior art includes a floor 20 and a chassis 10. The underframe 10 includes a bottom side rail 11, a bottom end rail 12, a first bottom cross rail 13, and a second bottom cross rail 15. The bottom side member 11 and the bottom end member 12 enclose a substantially rectangular bottom chassis 10. The first bottom cross member 13 has an inverted L-shape in cross section. As shown in fig. 3, the outer surface of the vertical side of the first bottom rail 13 is fitted on the side of the bottom end rail 12 facing the first bottom rail 13, and the bullnose 13a of the first bottom rail 13 and the bottom end 13b of the vertical side are welded to the bottom end rail 12. The second bottom rail 15 is arranged on the side of the first bottom rail 13 remote from the bottom end rail 12. The first bottom rail 13 and the second bottom rail 15 are disposed under the floor 20 to support the floor 20. The floor 20 may be a wood floor or an iron floor. The wood flooring is connected to the top surfaces of the first and second bottom beams 13 and 15 by self-tapping screws. The iron floor is welded to the top surfaces of the first bottom beam 13 and the second bottom beam 15. On the underframe 10, the cambered surface of the bullnose 13a of the first bottom beam 13 and the side of the bottom end beam 12 facing the first bottom beam 13 form a recess opening upwards. Thus, the powdery objects, granular objects or water are gathered in the grooves, and the grooves are not easy to clean. In the prior art, intermittent welding is adopted between the first bottom cross beam 13 and the bottom end beam 12, that is, along the length direction of the first bottom cross beam 13, between the first bottom cross beam 13 and the bottom end beam 12, at the bullnose angle 13a of the first bottom cross beam 13 and at the bottom end 13b of the vertical edge, after welding a first preset length, after a welding interval of a second preset length, then welding a first preset length, and so on, until the whole first bottom cross beam 13 is welded on the bottom end beam 12. There are thus a plurality of welding intervals arranged at intervals between the first bottom cross beam 13 and the bottom end beam 12. In order to prevent water from entering the welding space between the first bottom cross member 13 and the bottom end beam 12, rust is caused in the welding portion between the first bottom cross member 13 and the bottom end beam 12. The prior art adds a sealant at the welding interval between the first bottom cross member 13 and the bottom end member 12.
In the prior art, a groove exists between the first bottom cross beam 13 and the bottom end beam 12. When the container adopts the wood floor, the mounting hole for mounting the self-tapping screw needs to be drilled on the wood floor. Therefore, the wood dust generated during drilling can fall into the grooves, and is not easy to clean. When the sealant is added at the welding interval between the first bottom cross beam 13 and the bottom end beam 12, the sealant is adhered to the wood chips in the groove, so that the sealing performance of the sealant is reduced, and water is accumulated in the groove. The accumulated water gradually reduces the corrosion resistance of the paint at the welding seam of the first bottom cross beam 13 and the bottom end beam 12, and gradually reduces the corrosion resistance of the sealant at the welding interval of the first bottom cross beam 13 and the bottom end beam 12, so that the corrosion resistance of the paint at the welding seam of the first bottom cross beam 13 and the bottom end beam 12 is invalid, and the corrosion resistance of the sealant at the welding interval of the first bottom cross beam 13 and the bottom end beam 12 is invalid, so that the welding position of the first bottom cross beam 13 and the bottom end beam 12 is exposed in the accumulated water in the air or the groove, so that the welding position of the first bottom cross beam 13 and the bottom end beam 12 is rusted, and the welding connection between the first bottom cross beam 13 and the bottom cross beam is invalid.
In the prior art, the welding is performed in the longitudinal direction of the first bottom cross member 13, so that the welding seam between the first bottom cross member 13 and the bottom end beam has a large length and a large welding time.
Accordingly, there is a need to provide a container that at least partially addresses the above-described problems.

As shown in fig. 4, only a schematic view of the container chassis 110 and floor 120 assembled together is shown in fig. 4 for simplicity.
As shown in fig. 4, in the present embodiment, the container includes a floor 120 of a flat plate structure. The floor 120 is used to carry items placed in the receiving cavity of the container. The floor 120 may be a wood floor or an iron floor. In this embodiment, the floor panel 120 may be a wood floor panel.
The container of the present embodiment also includes a chassis 110. The bottom chassis 110 serves to support the floor 120. Specifically, the bottom chassis 110 includes two bottom side beams 111 and two bottom end beams 112 that are parallel to each other. The cross-sectional shape of the bottom side member 111 may be an i-shaped structure, and the cross-sectional shape of the bottom end member 112 may be an i-shaped structure. Of course, the cross-sectional shape of the bottom side member 111 and the cross-sectional shape of the bottom end member 112 may have other configurations, and may be set as required by those skilled in the art. In the present embodiment, two bottom side members 111 are connected to both ends of each bottom end member 112, respectively, and an end of each bottom side member 111 is connected to an end of each bottom end member 112, and the two bottom side members 111 and the two bottom end members 112 are connected end to enclose a substantially rectangular chassis 110.

A first gap a is provided between the first bottom cross member 113 and the bottom end beam 112. Therefore, no groove exists between the bullnose of the first bottom beam 113 and the bottom end beam 112, and powdery objects, granular objects and liquid (such as rainwater) can fall out of the bottom frame 110 from the first gap A between the first bottom beam 113 and the bottom end beam 112, so that the powdery objects, granular objects and liquid are prevented from being accumulated in the groove and inconvenient to clean, and the anti-corrosion performance of the first bottom beam 113 and the bottom end beam 112 is improved. Preferably, the chassis 110 includes two first bottom beams 113 disposed at intervals, one first bottom beam 113 and one bottom end beam 112 having a first gap a therebetween, and the other first bottom beam 113 and the other bottom end beam 112 having a first gap a therebetween. Further preferably, the first bottom cross member 113 and the bottom side member 111 are welded together. Thus, the first bottom cross member 113 and the bottom side member 111 have a small connecting length and a short welding distance.
Preferably, the first gap A is in the range of 5 mm.ltoreq.A.ltoreq.400 mm. Thereby facilitating processing of the chassis 110. Further preferably, a=50 mm.
Preferably, as shown in fig. 4, the cross-sectional shape of the first bottom rail 113 is C-shaped, Z-shaped, L-shaped, or rectangular. Thereby, the degree of freedom of selection of the type of the first floor beam 113 is increased. In the present embodiment, the cross-sectional shape of the first bottom beam 113 is C-shaped, that is, the first bottom beam 113 is made of C-shaped channel steel.
In this embodiment, the chassis 110 further includes a second bottom beam 115 spaced apart from the first bottom beam 113.

Preferably, both ends of the second bottom cross member 115 are welded to the bottom side member 111.
In the present embodiment, the cross-sectional shape of the second bottom beam 115 may be C-shaped, Z-shaped, L-shaped, or rectangular.

In this embodiment, the second bottom beam 115 has a C-shaped cross-section, that is, the second bottom beam 115 is made of C-shaped channel steel. In the present embodiment, as shown in fig. 4, the opening of the C-shaped channel of the first bottom rail 113 is directed toward the second bottom rail 115.
In the present embodiment, the floor panel 120 is remote from the bottom end rail 112 and the bottom side rail 111. The second bottom rail 115 and the first bottom rail 113 are used to support the floor 120. Specifically, as shown in fig. 4, the chassis further includes a plurality of tapping screws by which the floor panel 120 is fixedly coupled to the top surface of the first bottom rail 113 and the top surface of the second bottom rail 115. Thus, the second bottom rail 115 and the floor 120 form a generally T-shaped structure.
In the present embodiment, the distance between the end surface of the floor panel 120 facing the bottom end beam 112 and the end surface of the bottom end beam 112 facing the first bottom cross beam 113 is smaller than the first gap a. I.e. the end surface of the floor panel 120 facing the bottom end beam 112 extends beyond the first bottom rail 113 to form a cantilever beam structure.
