[0001] This utility model relates to the field of container technology, specifically to a container chassis mounting structure and a container. Background Technology

[0002] The container's underframe includes corner brackets, two bottom side beams, a bottom crossbeam, and a steel floor. The corner brackets are located at the corners of the underframe. The two bottom side beams are positioned opposite each other, with their end faces welded to the corner brackets. Each bottom side beam has a lower support plate located above the corner bracket. The lower support plate extends outwards, and its outer end bends upwards and outwards to form an upper support plate. Side plates are welded to the top surface of the upper support plate. The two ends of the bottom crossbeam are welded to the inner sides of the two bottom side beams. The end of the steel floor overlaps the top surface of the lower support plate, and the two are welded together. However, the steel floor requires a large installation space, resulting in a reduction in the container's internal space. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a container chassis installation structure and container that can save installation space and simplify the structure.

[0004] To achieve the above objectives, the embodiments of this utility model adopt the following technical solutions: The container chassis installation structure includes two bottom side beams, multiple bottom crossbeams, and a steel floor. The two bottom side beams are arranged opposite each other and extend along the longitudinal direction of the base frame. Each bottom side beam includes a web plate. The lower end and the upper end of the web plate are bent outward to form a lower wing plate and an upper wing plate, respectively. A chamfer is formed between the upper wing plate and the web plate. The chamfer is connected to the web plate and the upper wing plate and forms a support part. The two ends of the multiple bottom crossbeams are respectively welded and fixed between the inner sides of the two webs and distributed along the longitudinal direction. The steel floor is laid on the top surface of the multiple bottom crossbeams and has a side near the chamfer. A weld is formed between the side and the support, and the weld is filled with solder.

[0005] Furthermore, a weld is formed between the side surface of the side portion and the inner surface of the support portion.

[0006] Furthermore, the thickness of the steel floor is less than or equal to the thickness of the web, wherein the thickness of the steel floor is 2~5mm and the thickness of the web is 3~6mm.

[0007] Furthermore, the height difference between the top surface of the steel floor and the top surface of the upper wing plate is 0~5mm.

[0008] Furthermore, the chamfer is a rounded corner, and the side surface of the side portion is offset inward relative to the outer side of the rounded corner.

[0009] Furthermore, when viewed in a direction perpendicular to the inner wall of the web, the projection of the side portion lies within the projection of the chamfer, the bottom edge of the side portion contacts the inner surface of the support portion so that the support portion supports the side portion, and a weld is formed between the bottom surface of the side portion and the inner surface of the support portion.

[0010] Furthermore, the upper wing plate and the lower wing plate are perpendicular to the web plate, the multiple bottom crossbeams are evenly distributed along the longitudinal direction, and the two end faces of the bottom crossbeams are respectively welded to the inner sidewalls of the two web plates.

[0011] The container underframe installation structure of this utility model forms a support part at the chamfer of the bottom side beam. A weld is formed between the side of the steel floor and the support part, and the weld is filled with welding material to achieve welding between the side and the support part. That is, the side is directly welded to the chamfer, so that the bottom side beam does not need to be equipped with a lower support plate for overlapping the steel floor, thereby saving installation space and simplifying the structure.

[0012] This utility model embodiment also provides a container, including the container chassis mounting structure described in any of the above embodiments. Attached Figure Description

[0014] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments: like Figures 1 to 3 As shown, this utility model embodiment provides a container chassis mounting structure, applied to dry cargo containers, defining a transverse direction Y and a longitudinal direction X perpendicular to the transverse direction Y; the container chassis 100 mounting structure includes two bottom side beams 1, multiple bottom crossbeams 2 and a steel floor 3, the multiple bottom crossbeams 2 are fixed between the two bottom side beams 1, and the steel floor 3 is laid on the multiple bottom crossbeams 2.

[0015] Two bottom side beams 1 are arranged opposite each other and parallel to each other, and extend along the longitudinal direction X of the base frame 100. The thickness of the bottom side beams 1 is 3~6mm. Each bottom side beam 1 includes a web plate 11. The lower end and the upper end of the web plate 11 are bent outward to form a lower wing plate 12 and an upper wing plate 13, respectively. The upper wing plate 13 and the lower wing plate 12 are both perpendicular to the web plate 11, so that the bottom side beam 1 is C-shaped. A side plate 4 is welded to the top surface of the upper wing plate 13. A chamfer 14 is formed between the upper wing plate 13 and the web plate 11. The chamfer 14 is connected to the web plate 11 and the upper wing plate 13 and forms a support part 141. In this embodiment, the chamfer 14 is a rounded corner.

[0016] The two ends of the multiple bottom crossbeams 2 are welded and fixed between the inner sides of the two web plates 11 and distributed along the longitudinal direction X. Specifically, the multiple bottom crossbeams 2 are evenly distributed along the longitudinal direction X, and the two end faces of the bottom crossbeams 2 are welded to the inner sidewalls of the two web plates 11 respectively.

[0017] The steel floor 3 is laid on the top surface of multiple bottom crossbeams 2 and has a side 31 near the chamfer 14. A weld 32 is formed between the side 31 and the support 141. The weld 32 is filled with welding material to achieve welding between the side 31 and the support 141. That is, the side 31 is directly welded to the chamfer 14, so that the bottom side beam 1 does not need to be equipped with a lower support plate for overlapping the steel floor 3, thereby saving installation space and simplifying the structure. To ensure sufficient installation space for the steel base plate 3 at the chamfer 14 for welding, the thickness of the steel base plate 3 is set to be less than or equal to the thickness of the web plate 11. Specifically, the thickness of the steel base plate 3 is 2-5 mm, the thickness of the web plate 11 is 3-6 mm, and the height difference H between the top surface of the steel base plate 3 and the top surface of the upper flange 13 is 0-5 mm. This means the top surface of the steel base plate 3 is flush with the top surface of the upper flange 13 or has a step difference of less than 5 mm, facilitating welding. Since the step difference is small, the inner width can be approximated by the side plate 4, avoiding the inner width being based on the bottom side beam 1 due to its influence. In this embodiment, the thickness of the steel base plate 3 is 4 mm, the thickness of the web plate 11 is 4 mm, and the height difference H between the top surface of the steel base plate 3 and the top surface of the upper flange 13 is 1 mm.

[0018] A weld 32 is formed between the side surface 311 of the side portion 31 and the inner surface of the support portion 141. This weld 32 is an upper weld, and the side surface 311 of the side portion 31 is offset inward relative to the outer side of the rounded corner, so that the steel floor 3 makes way for the side plate 4, which facilitates the welding of the side plate 4. A weld 32 is formed between the bottom surface of the side portion 31 and the inner surface of the support portion 141. This weld 32 is a lower weld. The lower weld is filled with welding material as much as possible to improve the welding strength and prevent contaminants from entering the lower weld. When viewed in a direction perpendicular to the inner wall of the web 11, the projection of the side portion 31 is located within the projection of the chamfer 14, ensuring that the height of the side portion 31 does not exceed the top surface of the upper flange 13. The bottom side edge of the side portion 31 contacts the inner surface of the support portion 141 so that the support portion 141 supports the side portion 31, which facilitates welding.

[0019] The container underframe installation structure of this utility model forms a support part at the chamfer of the bottom side beam. A weld is formed between the side of the steel floor and the support part, and the weld is filled with welding material to achieve welding between the side and the support part. That is, the side is directly welded to the chamfer, so that the bottom side beam does not need to be equipped with a lower support plate for overlapping the steel floor, thereby saving installation space and simplifying the structure.

[0020] This utility model embodiment also provides a container (not shown), including the container chassis mounting structure described in any of the above embodiments.

[0021] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or make equivalent substitutions for some of the technical features.
