Description

Technical Field

[0001] This utility model relates to a sidewall assembly and a container. Background Technology

[0002] Containers are divided into open-top containers and closed-top containers. Both consist of a base frame (which is rectangular in shape), a front end assembly and a door assembly connected to the two short sides of the base frame, and side walls connected to the two long sides of the base frame. The base frame, front end assembly, door assembly, and side walls connect to form a rectangular channel. For closed-top containers, the opening of this rectangular channel is closed by a top cover.

[0003] The sidewall of a traditional container consists of an upper side beam and a lower side beam extending along the length of the container. The upper side beam is located directly above the lower side beam. The upper edge of a single corrugated sidewall panel is welded to the lower surface of the upper side beam, and the lower edge of the corrugated sidewall panel is welded to the upper surface of the lower side beam.

[0004] Traditional corrugated sidewall panels are prone to deformation due to their large area, resulting in a weak overall structural stability. Utility Model Content

[0005] One objective of this invention is to provide a sidewall assembly that improves the structural stability of the sidewall assembly while significantly saving the space occupied by the sidewall assembly. Another objective of this invention is to provide a shipping container.

[0006] This utility model provides the following technical solution:

[0007] A sidewall assembly, comprising:

[0008] The upper beam extends horizontally;

[0009] One or more side wall columns, the upper ends of which are welded to the lower surface of the upper side beam, all extending in the vertical direction;

[0010] Multiple corrugated sidewall panels are spaced apart along the extension direction parallel to the upper side beam. A side wall post is provided between each adjacent corrugated sidewall panel. The upper end of the corrugated sidewall panel is welded to the lower surface of the upper side beam. The edge area where the corrugated sidewall panel meets the adjacent side wall post is welded to the side wall post.

[0011] The sidewall side column includes an integrally formed first rectangular plate, second rectangular plate, third rectangular plate, fourth rectangular plate, fifth rectangular plate, sixth rectangular plate, seventh rectangular plate, and eighth rectangular plate. These rectangular plates (the first rectangular plate, the second rectangular plate, the third rectangular plate, the fourth rectangular plate, the fifth rectangular plate, the sixth rectangular plate, the seventh rectangular plate, and the eighth rectangular plate) are connected end to end along one circumference of the sidewall side column to form the outer contour of the sidewall side column. The long sides of the first rectangular plate, the second rectangular plate, the third rectangular plate, the fourth rectangular plate, the fifth rectangular plate, the sixth rectangular plate, the seventh rectangular plate, and the eighth rectangular plate extend in the vertical direction.

[0012] Wherein, the first rectangular plate is perpendicularly connected to the second rectangular plate, the second rectangular plate is perpendicularly connected to the third rectangular plate, the seventh rectangular plate is perpendicularly connected to the eighth rectangular plate, and the eighth rectangular plate is perpendicularly connected to the first rectangular plate, and the five are connected to form a rectangular tube with a notch on the inside.

[0013] The fourth rectangular plate, the fifth rectangular plate, and the sixth rectangular plate are connected to form a trapezoidal tube with a missing bottom edge;

[0014] Wherein, the trapezoidal tube missing its bottom edge is located inside the rectangular tube with a notch on its inner side, and the notch of the trapezoidal tube missing its bottom edge matches the notch of the rectangular tube with a notch on its inner side;

[0015] The third rectangular plate and the seventh rectangular plate are both welded to the edge of the side wall corrugated plate.

[0016] A trapezoidal tube refers to a straight tube with a trapezoidal cross-section, while a rectangular tube refers to a straight tube with a rectangular cross-section.

[0017] To facilitate understanding the shape of the sidewall and side column, let's assume the sidewall and side column are solid. Then, its cross-section would consist of a rectangular base and a trapezoidal boss located on one side of the rectangular base. The side where the trapezoidal boss connects to the rectangular base is the lower base (i.e., the longer base) of the trapezoidal boss.

[0018] The sidewalls are used to construct the shipping container. In use, the corrugated sidewall panels are welded to the third and seventh rectangular flat plates, and the corrugated sidewall panels do not extend beyond the fifth rectangular flat plate into the container. This allows for a relatively thin overall thickness of the sidewall assembly. The sidewall columns effectively support the upper side beams. The corrugated sidewall panels are divided into multiple smaller pieces, and the sidewall columns provide additional support, enhancing the mechanical strength of the sidewall panels. Furthermore, the dihedral angles between the third and fourth rectangular flat plates, and between the sixth and seventh rectangular flat plates, are obtuse, further dispersing the overall structural stress and ensuring the structural stability of the sidewall columns themselves. In summary, the mechanical strength of the sidewall assembly is increased without increasing its thickness.

[0019] In some embodiments, the cross-section of the rectangular tube with the notch on the inner side is a rectangle with the notch located at the long side of the rectangle. The sidewall and sidepost themselves are flat structures, and the thickness direction of the sidewall and sidepost is also the thickness direction of the sidewall as a whole.

[0020] In some embodiments, the cross-section of the trapezoidal tube lacking a base is an isosceles trapezoid. This also makes the stress on the sidewall and side column more distributed, improving the mechanical strength of the sidewall and side column itself.

[0021] In some embodiments, the ratio of the distance between the third rectangular plate and the first rectangular plate to the distance between the fifth rectangular plate and the first rectangular plate is greater than 0.5. In other words, the dimension of the trapezoidal tube missing its bottom edge in the thickness direction of the sidewall is smaller than the dimension of the rectangular tube with the notch on its inner side in the thickness direction of the sidewall. The rectangular tube with the notch on its inner side plays a major mechanical support role.

[0022] In some embodiments, the sidewall side column further includes a ninth rectangular plate and a tenth rectangular plate, the long side of which is vertical, one long side of each of which is connected, and the cross-section of the two is V-shaped.

[0023] The joint between the ninth rectangular plate and the tenth rectangular plate is connected to the middle of the first rectangular plate.

[0024] The other long side of the ninth rectangular plate is connected to the corner where the third rectangular plate and the fourth rectangular plate are connected, and the other long side of the tenth rectangular plate is connected to the corner where the sixth rectangular plate and the seventh rectangular plate are connected; or the other long side of the ninth rectangular plate is connected to the corner where the fourth rectangular plate and the fifth rectangular plate are connected, and the other long side of the tenth rectangular plate is connected to the corner where the fifth rectangular plate and the sixth rectangular plate are connected.

[0025] The ninth and tenth rectangular plates serve to mechanically reinforce the side walls and side columns, acting as reinforcing ribs.

[0026] In some embodiments, the dihedral angle formed by the ninth rectangular plate and the tenth rectangular plate toward the fifth rectangular plate is in the range of 60° to 140°.

[0027] The small dihedral angle results in an excessively large dimension of the side wall column in the thickness direction of the side wall assembly, thus leading to an excessively large thickness of the side wall assembly.

[0028] The excessively large dihedral angle results in the rectangular area of ​​the side wall and side column being too small in the thickness direction of the side wall, which reduces the mechanical strength of the side wall and side column.

[0029] In some embodiments, a lower side beam parallel to the upper side beam is also included, with the lower end of the side wall column welded to the upper surface of the lower side beam, and the lower end of the side wall corrugated plate welded to the upper surface of the lower side beam. The lower side wall forms the lower boundary of the side wall assembly.

[0030] In some other embodiments, the sidewalls are missing the lower side beam, which is a component of the container's underframe. In the assembled state of the container, the corrugated sidewall panels are also welded to the upper surface of the lower side beam.

[0031] Based on the same inventive concept, this utility model also provides a container, including the aforementioned sidewall composition.

[0032] The container can be an open-top container or a closed-top container.

[0033] A container includes at least a door assembly, a base frame assembly, a front end assembly, and two side walls; the door assembly and the front end assembly are opposite each other, and the two side walls are opposite each other, and the four together enclose the internal space of the cuboid; the base frame assembly closes the bottom opening of the cuboid space.

[0034] In some embodiments, the container also includes a door corner post, which includes an integrally formed first columnar structure and a first triangular overlap portion, both of which extend vertically. The outer contour of the cross-section of the first columnar structure is basically rectangular, and the cross-section of the first triangular overlap portion is a right triangle. The first triangular overlap portion is located outside the first columnar structure, and the first triangular overlap portion shares a right-angled side with the first columnar structure. The outermost edge of the entire corrugated sidewall is welded to the exposed right-angled side of the first triangular overlap portion.

[0035] When the container is in a horizontal position, the door end corner posts extend vertically as part of the door end assembly.

[0036] In some embodiments, the container also includes a front corner post, which includes an integrally formed second columnar structure and a second triangular overlap, both of which extend vertically. The outer contour of the cross-section of the second columnar structure is basically rectangular, and the cross-section of the second triangular overlap is a right triangle. The second triangular overlap is located outside the second columnar structure, and the second triangular overlap shares a right-angled side with the second columnar structure. The outermost edge of the entire corrugated sidewall is welded to the exposed right-angled side of the second triangular overlap.

[0037] When the container is in a horizontal position, the front corner posts extend vertically and are part of the front end.

[0038] The sidewall of this invention has high mechanical strength and good overall thickness control. Attached Figure Description

[0050] The present invention will be further described below with reference to specific embodiments, but the scope of protection of the present invention is not limited thereto.

[0051] Note: The directional and positional relationships defined in this utility model refer to the directional and positional relationships when the container composed of the side walls is placed horizontally.

[0052] Example 1

[0053] refer to Figures 1 to 4 As shown, Embodiment 1 provides a sidewall assembly for use in the construction of a shipping container. Two sets of sidewall assemblies are arranged opposite each other in the container. Each set of sidewall assemblies includes: an upper side beam 31, two sidewall columns 33, and three sidewall corrugated panels (a first sidewall corrugated panel 32, a second sidewall corrugated panel 34, and a third sidewall corrugated panel 35).

[0054] refer to Figure 1 The upper beam 31 extends horizontally. The cross-section of the upper beam 31 is rectangular. Under normal use, the upper surface of the upper beam 31 is horizontal.

[0055] The upper ends of the two side wall columns 33 are welded to the lower surface of the upper side beam 31, and both side wall columns 33 extend in the vertical direction.

[0056] Three corrugated sidewall panels (first corrugated sidewall panel 32, second corrugated sidewall panel 34, and third corrugated sidewall panel 35) are spaced apart along the extension direction parallel to the upper side beam 31. A sidewall post 33 is provided between each adjacent corrugated sidewall panel. The upper end of the corrugated sidewall panel is welded to the lower surface of the upper side beam 31, and the edge area where the corrugated sidewall panel meets the adjacent sidewall post 33 is welded to the sidewall post 33.

[0057] refer to Figure 2The side wall and side column 33 includes an integrally formed first rectangular plate 331, second rectangular plate 332, third rectangular plate 333, fourth rectangular plate 334, fifth rectangular plate 335, sixth rectangular plate 336, seventh rectangular plate 337 and eighth rectangular plate 338. These rectangular plates are connected end to end along one circumference of the side wall and side column 33 to form the outer contour of the side wall and side column 33. The long sides of the first rectangular plate 331, second rectangular plate 332, third rectangular plate 333, fourth rectangular plate 334, fifth rectangular plate 335, sixth rectangular plate 336, seventh rectangular plate 337 and eighth rectangular plate 338 extend in the vertical direction.

[0058] The first rectangular plate 331 is perpendicularly connected to the second rectangular plate 332, the second rectangular plate 332 is perpendicularly connected to the third rectangular plate 333, the seventh rectangular plate 337 is perpendicularly connected to the eighth rectangular plate 338, and the eighth rectangular plate 338 is perpendicularly connected to the first rectangular plate 331. The five are connected to form a rectangular tube with a notch on the inside.

[0059] The fourth rectangular plate 334, the fifth rectangular plate 335, and the sixth rectangular plate 336 are connected to form a trapezoidal tube with a missing bottom edge.

[0060] The trapezoidal tube missing its base is located inside the rectangular tube with a notch on the inside, and the notch in the trapezoidal tube with the missing base matches the notch in the rectangular tube with a notch on the inside. The second rectangular plate 332 and the eighth rectangular plate 338 are symmetrically arranged, as are the fourth rectangular plate 334 and the sixth rectangular plate 336. The side wall and side column 33 are symmetrical from left to right, and the plane of symmetry is perpendicular to the first rectangular plate 331 and parallel to the extension direction of the side wall and side column 33.

[0061] Combination Figure 2 and Figure 3 Both the third rectangular plate 333 and the seventh rectangular plate 337 are welded to the edge of the side wall corrugated plate.

[0062] The trapezoidal tubes mentioned above refer to straight tubes with a trapezoidal cross-section, while the rectangular tubes refer to straight tubes with a rectangular cross-section.

[0063] To facilitate understanding of the shape of the side wall column 33, it is assumed that the side wall column 33 is solid. Then its cross-section presents a rectangular base and a trapezoidal boss located on one side of the rectangular base. The side where the trapezoidal boss connects to the rectangular base is the lower base (i.e., the longer base) of the trapezoidal boss.

[0064] The sidewalls are used to construct the container. During cargo transport, the corrugated sidewall panels are welded to the third rectangular plate 333 and the seventh rectangular plate 337, and do not extend beyond the fifth rectangular plate 335 into the container. This allows for a relatively thin overall thickness of the sidewall assembly. The sidewall columns 33 effectively support the upper side beam 31. The corrugated sidewall panels are divided into multiple smaller pieces, and the sidewall columns 33 provide additional support, enhancing the mechanical strength of the sidewall panels. Furthermore, the dihedral angles between the third and fourth rectangular plates 333 and between the sixth and seventh rectangular plates 337 are obtuse, further dispersing structural stress and ensuring the structural stability of the sidewall columns 33. In summary, the mechanical strength of the sidewall assembly is increased without increasing its thickness.

[0065] refer to Figure 3 The cross-section of the rectangular tube with a notch on the inner side is a rectangle with a notch, and the notch is located at the long side of the rectangle. The side wall and side column 33 are flat structures, and the thickness direction of the side wall and side column 33 is also the thickness direction of the side wall.

[0066] refer to Figure 3 The cross-section of the trapezoidal tube lacking the base is an isosceles trapezoid. This also makes the stress on the side wall and side column 33 more dispersed, improving the mechanical strength of the side wall and side column 33 itself.

[0067] The trapezoidal tube missing its bottom edge has a thickness dimension of 7mm in the side wall, while the rectangular tube with a notch on the inside has a thickness dimension of 50mm in the side wall.

[0068] In this embodiment, refer to Figure 2 and Figure 3 As shown, a ninth rectangular plate 339 and a tenth rectangular plate 33a are provided inside the rectangular tube and the trapezoidal tube. The long side of the two plates is in the vertical direction, and one long side of each plate is connected. The cross-section of the two plates is V-shaped.

[0069] The junction of the ninth rectangular plate 339 and the tenth rectangular plate 33a is connected to the middle of the first rectangular plate 331.

[0070] The other long side of the ninth rectangular plate 339 is connected to the corner where the third rectangular plate 333 and the fourth rectangular plate 334 are connected, and the other long side of the tenth rectangular plate 33a is connected to the corner where the sixth rectangular plate 336 and the seventh rectangular plate 337 are connected.

[0071] The ninth rectangular plate 339 and the tenth rectangular plate 33a serve to mechanically strengthen the side wall columns 33, acting as reinforcing ribs.

[0072] The dihedral angle formed by the ninth rectangular plate 339 and the tenth rectangular plate 33a toward the fifth rectangular plate 335 is 78°.

[0073] The dihedral angle is too small, which causes the side column 33 of the side wall to be too large in the thickness direction of the side wall, resulting in an excessively large thickness of the side wall.

[0074] The excessively large dihedral angle results in the rectangular area of ​​the side wall and side column 33 having an excessively small dimension in the thickness direction of the side wall, which reduces the mechanical strength of the side wall and side column 33.

[0075] The ninth rectangular plate 339, the tenth rectangular plate 33a, the side wall and the side column 33, and the rest of the structure are also integrally formed.

[0076] In this embodiment, the sidewalls do not include the lower side beams.

[0077] refer to Figure 4 The left-side structure (as a comparative example) assumes that the dimensions of the side wall post 33 along the thickness direction of the side wall composition remain unchanged, and its outer contour cross-section is rectangular. This side wall post is designated as the comparative side wall post 33b. The second side wall corrugated plate 34 and the third side wall corrugated plate 35 are welded to this comparative side wall post 33b, which will result in an increase in the thickness of the side wall composition, and the inner boundary of the side wall composition ( Figure 4 The upper boundary of the middle section is uneven.

[0078] refer to Figure 4 In the right-side structure (the structure of this utility model), the inner boundary of the side wall column 33 is basically flush with the inner boundaries of the second side wall corrugated plate 34 and the third side wall corrugated plate 35. This ensures that the thickness of the side wall does not increase and that the inner surface is flat.

[0079] Example 2

[0080] refer to Figure 7 The difference between Embodiment 2 and Embodiment 1 is only that: in the side wall side column 33, the joint of the ninth rectangular plate 339 and the tenth rectangular plate 33a is connected to the middle of the first rectangular plate 331, the other long side of the ninth rectangular plate 339 is connected to the corner where the fourth rectangular plate 334 and the fifth rectangular plate 335 are connected, and the other long side of the tenth rectangular plate 33a is connected to the corner where the fifth rectangular plate 335 and the sixth rectangular plate 336 are connected.

[0081] Example 3

[0082] The difference between Example 3 and Example 1 is that the side wall composition also includes a lower side beam, which is parallel to the upper side beam 31. The lower ends of the first side wall corrugated plate 32, the second side wall corrugated plate 34 and the third side wall corrugated plate 35 are welded to the upper surface of the lower side beam, and the lower ends of the side wall side column 33 are welded to the upper surface of the lower side beam.

[0083] Example 4

[0084] Example 4 provides a container comprising the sidewalls of Example 1.

[0085] This container can be an open-top container.

[0086] The container consists of a door assembly, a base frame assembly, a front end assembly, and two side walls. The door assembly and the front end assembly are opposite each other, and the two side walls are opposite each other. The four components together enclose and define the internal space of the cuboid. The base frame assembly closes the bottom opening of the cuboid space.

[0087] The lower side beam is integrated into the container's underframe assembly. In the assembled state of the container, the corrugated sidewall panels are also welded to the upper surface of the lower side beam. The upper surface of the lower side beam is horizontal.

[0088] refer to Figure 5 The container also includes door corner posts 13, which include an integrally formed first columnar structure 131 and a first triangular overlap portion 132, both of which extend vertically. The outer contour of the cross-section of the first columnar structure 131 is basically rectangular, and the cross-section of the first triangular overlap portion 132 is a right triangle. The first triangular overlap portion 132 is located outside the first columnar structure 131, and the first triangular overlap portion 132 shares a right-angled side with the first columnar structure 131. The outermost edge of the entire sidewall corrugated plate (i.e., the edge of the third sidewall corrugated plate 35 facing away from the second sidewall corrugated plate 34) is welded to the exposed right-angled side of the first triangular overlap portion 132.

[0089] When the container is in a horizontal position, the door corner posts 13 extend vertically, forming part of the door assembly. There are two door corner posts 13, which together form the rectangular frame structure of the door assembly. Doors are installed within the door assembly for opening the container.

[0090] refer to Figure 6The container also includes a front corner post 24, which includes an integrally formed second columnar structure 242 and a second triangular overlap portion 241, both of which extend vertically. The outer contour of the cross-section of the second columnar structure 242 is basically rectangular, and the cross-section of the second triangular overlap portion 241 is a right triangle. The second triangular overlap portion 241 is located outside the second columnar structure 242. The second triangular overlap portion 241 and the second columnar structure 242 share a right-angled side of the second triangular overlap portion 241. The outermost edge of the entire sidewall corrugated plate (i.e., the edge of the first sidewall corrugated plate 32 facing away from the second sidewall corrugated plate 34) is welded to the exposed right-angled side of the second triangular overlap portion 241.

[0091] In the horizontal configuration of the container, the front corner posts 24 extend vertically, forming part of the front end assembly. There are two front corner posts 24, which together constitute the rectangular frame structure of the front end assembly. The front end assembly is entirely enclosed and cannot be opened.

[0092] Except for the door end corner post 13 and the front end corner post 24, the remaining structural details of the above door end components, base frame components, and front end components can adopt conventional designs and will not be described in detail here.

[0093] Example 5

[0094] Example 5 provides a container, which differs from Example 4 only in that the container of Example 5 includes the sidewalls of Example 2.

[0095] Example 6

[0096] Example 6 provides a container, the only difference from the other examples of Example 4 is that Example 6 includes the side wall assembly of Example 3, and the lower surface of the lower side beam in the side wall assembly is welded to the base frame assembly.
