Description

Container, especially container for transporting goods

Technical Field

The present invention relates generally to the field of shipping containers and, more particularly, to a shipping container.

Background

Fig. 1 to 3 are sectional views schematically showing the assembly of the underframe 10 and the floor 20 of the container of the prior art.

As shown in fig. 1 to 3, the related art container includes a floor 20 and a base frame 10. The underframe 10 comprises a bottom side beam 11, a bottom end beam 12, a first bottom cross beam 13 and a second bottom cross beam 15. The bottom side beams 11 and the bottom end beams 12 enclose a substantially rectangular base frame 10. The cross-sectional shape of the first bottom cross member 13 is an inverted L-shape. As shown in fig. 3, the outer surface of the vertical side of the first bottom cross member 13 is fitted on the side of the bottom end beam 12 facing the first bottom cross member 13, and the bullnose 13a of the first bottom cross member 13 and the bottom end 13b of the vertical side are welded to the bottom end beam 12. The second bottom cross member 15 is arranged on the side of the first bottom cross member 13 remote from the bottom end beam 12. The first and second

bottom cross members

13 and 15 are disposed below the floor panel 20 to support the floor panel 20. The floor 20 may be a wood floor or an iron floor. The wood floor is connected to the top surfaces of the first bottom beam 13 and the second bottom beam 15 through self-tapping screws. The iron floor is welded to the top surfaces of the first bottom cross member 13 and the second bottom cross member 15. On the underframe 10, the cambered surface of the bullnose 13a of the first bottom cross member 13 and the side of the bottom end beam 12 facing the first bottom cross member 13 form a groove with an upward opening. Therefore, powdery objects, granular objects or water are gathered in the groove, and the groove is 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, after welding a first preset length between the first bottom cross beam 13 and the bottom end beam 12, at the position of the excircle corner 13a of the first bottom cross beam 13 and at the position of the bottom end 13b of the vertical edge along the length direction of the first bottom cross beam 13, and after welding an interval of a second preset length, the first preset length is welded, and the process is repeated until the whole first bottom cross beam 13 is welded on the bottom end beam 12. Such that there are a plurality of spaced apart weld spaces between the first bottom end beam 13 and the bottom end beam 12. In order to prevent water from entering the welding gap between the first bottom cross member 13 and the bottom end beam 12, which may cause rusting of the welded portion between the first bottom cross member 13 and the bottom end beam 12. The prior art adds sealant at the weld spacing between the first bottom cross member 13 and the bottom end beam 12.

In the prior art, there is a groove between the first bottom cross member 13 and the bottom end member 12. When the container adopts a wood floor, a mounting hole for mounting the self-tapping screw needs to be drilled on the wood floor. Like this, the saw-dust that produces during drilling can drop in the recess, and difficult clean up. After the sealant is added at the welding interval between the first bottom cross beam 13 and the bottom end beam 12, the sealant can be bonded with the wood chips in the groove, so that the sealing performance of the sealant is reduced; and water may accumulate in the grooves. The accumulated water gradually reduces the corrosion resistance of paint at the welding seam of the first bottom cross beam 13 and the bottom end beam 12, gradually reduces the corrosion resistance of sealant at the welding interval of the first bottom cross beam 13 and the bottom end beam 12, further disables the corrosion resistance of the paint at the welding seam of the first bottom cross beam 13 and the bottom end beam 12, disables the corrosion resistance of the sealant at the welding interval of the first bottom cross beam 13 and the bottom end beam 12, further exposes the welding part of the first bottom cross beam 13 and the bottom end beam 12 in the air or the accumulated water in the groove, enables the welding part of the first bottom cross beam 13 and the bottom end beam 12 to rust, and causes the failure of the welding connection of the first bottom cross beam 13 and the bottom cross beam.

In the prior art, the first bottom cross beam 13 is welded in the length direction, so the length dimension of the welding seam between the first bottom cross beam 13 and the bottom end beam is large, and the welding time is large.

There is therefore a need to provide a container that at least partially addresses the above problems.
