[0025] The general container roof includes at least two detachable panels 2. The riveted container roof disclosed in the embodiment of the utility model includes two top side beams 1 and four panels 2. Figures 3 to 5 The two top side beams 1 are located at the two ends of the container roof along the width direction, and the outer edge of the top side beam 1 is the outer edge of the container roof. The panel 2 is a flat plate or a blind wave plate. The specific style can be flexibly adjusted according to the usage scenario and strength requirements. The attached drawings all take the flat plate as an example. Figure 6 The panel 2 includes a main body 21 and a bending portion 22 , and the bending portion 22 is located at two ends of the main body 21 along the length direction of the top side beam 1 .

[0026] The top side beam 1 includes a first special-shaped plate 11 and a second special-shaped plate 12, which are welded to form a closed cavity 13. Four panels 2 are laid in sequence along the length direction of the top side beam 1 and riveted to the top side beam 1, and the riveted joint is located outside the closed cavity 13. A C-shaped crossbeam 3 is arranged between two adjacent panels 2, that is, the two adjacent panels 2 are connected and sealed by the C-shaped crossbeam 3, and a whole container top plate includes at least one C-shaped crossbeam 3. The two ends of the C-shaped crossbeam 3 are respectively fixed to the top side beam 1, the notch 33 of the C-shaped crossbeam 3 faces upward and the upper side surface of the C-shaped crossbeam 3 is flush with the upper side surface of the top side beam 1, and each panel 2 is riveted to the C-shaped crossbeam 3 and the riveted joint is located on both sides of the notch 33 of the C-shaped crossbeam 3. The panels 2 located at the two ends of the container top plate along the length direction are respectively riveted to the front fascia 5 and the rear fascia 6 of the top of the container, and the structure of the riveted joint is in accordance with the prior art as shown in the attached drawings.

[0027] See also Figure 7 The first special-shaped plate 11 is integrally formed, including a first horizontal portion 111, a first vertical portion 112, a second horizontal portion 113 and a first inclined portion 114 connected in sequence. The first horizontal portion 111 and the second horizontal portion 113 are located on the same side of the first vertical portion 112, and the first inclined portion 114 forms an obtuse angle with the second horizontal portion 113. The second special-shaped plate 12 is integrally formed, including a third horizontal portion 121, a second vertical portion 122, a second inclined portion 123 and a third vertical portion 124 connected in sequence. The second inclined portion 123 forms an obtuse angle with the second vertical portion 122, and the second inclined portion 123 forms an obtuse angle with the third vertical portion 124. The connection between the above parts is transitioned by an arc portion.

[0028] The third horizontal portion 121 is welded to the first horizontal portion 111, and the end of the third vertical portion 124 is welded to the plane of the second horizontal portion 113, thereby enclosing a closed cavity 13. In this embodiment, the third horizontal portion 121 and the first horizontal portion 111 are in the same plane, and the end of the third horizontal portion 121 is welded to the end of the first horizontal portion 111, and the welding point is just above the container side plate 7 to enhance the hardness; in other embodiments, the third horizontal portion 121 and the first horizontal portion 111 can also be staggered in the horizontal plane, so that the planes of the two are welded to each other. The body 21 of the panel 2 is riveted to the second horizontal portion 113 at both ends along the length direction of the C-shaped crossbeam 3, and the riveted part is located outside the closed cavity 13. If there is a water leak at the riveted part, the water will flow out along the outside of the second special-shaped plate 12 and will not enter the closed cavity 13, causing maintenance difficulties.

[0029] See also Figures 8 to 10, the top side beam 1 is provided with a notch 14, and the opening direction of the notch 14 faces upward to accommodate the C-shaped cross beam 3. The C-shaped cross beam 3 includes a pallet 31 and a riveting plate 32 integrally formed. The cross section of the pallet 31 is in a "凵" shape. The riveting plate 32 is parallel to the bottom end of the pallet 31, and there is a riveting plate 32 on each side of the opening of the pallet 31. A notch 33 of the C-shaped cross beam 3 is formed between the two riveting plates 32.

[0030] At least the outermost end of the C-shaped cross beam 3 is the outermost edge of the notch 14 to prevent rainwater from entering the closed cavity 13 through the notch 14 of the top side beam 1. If the C-shaped cross beam 3 is made of a material that is easy to weld, the outer side of the C-shaped cross beam 3 is directly welded to the top side beam 1 inside the notch 14. If the C-shaped cross beam 3 is made of a material that is not easy to weld, an L-shaped angle steel 4 can be provided on the top side beam 1 to assist in fixing the end of the C-shaped cross beam 3 to the top side beam 1. Refer to Figures 9 to 11 . The end of the C-shaped cross beam 3 passes through the notch 14 and extends outward, and the outermost end of the C-shaped cross beam 3 does not exceed the outermost edge of the top side beam 1. The L-shaped angle steel 4 is located directly below the notch 14. One side is welded parallel to the third vertical part 124 of the second special-shaped plate 12, and the other side is connected to the bottom end of the extended part of the C-shaped cross beam 3 through a bolt 41. At the same time, it is locked and connected through a nut 42 on the other side of the bolt 41. In this solution, semicircular slots 34 need to be opened in advance at the ends of the riveting plates 32. The two semicircular slots 34 and the notch 33 in the middle form a space for the bolt 41 to pass through. After the bolt 41 passes through the riveting plate 32 and enters the inner space of the pallet 31, the bottom end of the pallet 31 can be connected to the L-shaped angle steel 4.

[0031] The installation of the C-shaped cross beam 3, on the one hand, plays a role in supporting the frame of the container top plate, and on the other hand, provides a basis for the transverse riveting and fixing of the panel 2: each riveting plate 32 is riveted to a panel 2, and both ends of the main body 21 of the panel 2 along the length direction of the top side beam 1 are riveted to the riveting plate 32. The bending parts 22 of two adjacent panels 2 are in direct contact, the main bodies 21 are neatly joined at the seams, and all the bending parts 22 pass through the notch 33 of the C-shaped cross beam 3 so that when water leaks at the riveting part, the water can enter the inner side of the pallet 31 and flow out from both ends of the pallet 31.

[0032] In order to make the panel 2 fit more closely with the top side beam 1 and the C-shaped cross beam 3, single-sided adhesive pads are provided at the direct contact places between the panel 2 and the top side beam 1, between the panel 2 and the C-shaped cross beam 3, and between two adjacent panels 2. The adhesive pads are not shown in the figure. After being fixed by rivets or bolts 41, the waterproof effect of the entire container top plate can be better.

[0033] In summary, the utility model optimizes the riveting structure between panel 2 and top side beam 1, and between panel 2 and panel 2, and adjusts all riveted joints to the outside of the container body. On the basis of ensuring strength, it enhances the waterproof effect of the top of the container such as plate-type container or aluminum box whose top plate is not convenient to weld, alleviates the leakage problem, and solves the problem of uneven joints between panels 2.

[0034] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
