[0056] Unless otherwise stated, the numerical ranges herein include not only the entire range within its two endpoints but also include several sub-ranges contained therein.

[0057] Now, exemplary embodiments according to the present utility model will be described in more detail with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in a variety of different forms and should not be interpreted as being limited to the embodiments described herein. It should be understood that these embodiments are provided to make the disclosure of the present utility model thorough and complete, and to fully convey the concepts of these exemplary embodiments to those of ordinary skill in the art.

[0058] The lintel beam is located above the container door and is an important component of the container door frame structure. The main function of the lintel beam is to bear the weight and pressure of the cargo above and prevent the cargo from pressing on the door. The lintel board is usually overlapped above the lintel, and its edge part is often higher than the middle part. When rainwater or other liquids flow onto the lintel board, since the edge part is higher than the middle part, the water will stay at the edge and it is difficult to drain smoothly, thus forming water accumulation.

[0059] Reference Figure 1-Figure 6 The utility model provides a door lintel, comprising a door lintel crossbeam and a door lintel board.

[0060] Reference Figure 2-Figure 3 In some embodiments of the present invention, the lintel crossbeam includes an outer plate 10 and an inner plate 20. The lintel board includes a first connecting plate 40 and a second connecting plate 50. The projection of the top surface of the outer plate 10 along the first direction D1 is a first straight edge 11, and the first straight edge 11 is connected to the first connecting plate 40. The inner plate 20 and the outer plate 10 are opposite and spaced along the first direction D1, and the projection of the top surface of the inner plate 20 along the first direction D1 is a first convex edge 21 with a high middle and low sides, and the first convex edge 21 is connected to the second connecting plate 50. According to the lintel provided by the present invention, the inner plate 20 of the lintel crossbeam is set to a configuration with a high middle and low sides, and the second connecting plate 50 is overlapped to the inner plate 20, and the accumulated water can be drained from both sides of the box. Since the first straight edge 11 is higher than the first convex edge 21, the accumulated water will not gather above the second connecting plate 50, eliminating the quality risk of the paint anti-corrosion life of the lintel board and the water-soaked and fallen trademark due to accumulated water. The arrangement of the outer plate 10 and the first connecting plate 40 enhances the strength of the container and facilitates the connection of the door lintel with other structures.

[0061] In the present invention, the top surface of the outer panel 10 is set as a straight edge, which ensures the firmness of the connection between the lintel beam and the lintel board, and at the same time ensures that the lintel serves as the basis of the load-bearing structure and provides a straight plane for load-bearing. The top surface of the inner panel 20 is set as a convex edge, providing a connection structure with a certain slope. After the lintel board is installed on the lintel beam, an arched structure is formed to prevent water accumulation at the corner of the lintel board.

[0062] Optionally, the lintel crossbeam further includes a connector 30. The connector 30 is connected between the inner plate 20 and the outer plate 10. Optionally, the inner plate 20, the outer plate 10, and the connector 30 are an integrally formed structure. Optionally, the cross section of the lintel crossbeam is roughly "U"-shaped. Through the design of the outer plate 10, the inner plate 20, and the connector 30, the lintel crossbeam can provide sufficient support for the lintel board to ensure the stability of the lintel board. Optionally, the lintel board is welded to the lintel crossbeam. Specifically, the first connecting plate 40 is welded to the outer plate 10, and the second connecting plate 50 is welded to the inner plate 20.

[0063] Reference Figure 4-Figure 5 The lintel plate includes a first connecting plate 40 and a second connecting plate 50. The first connecting plate 40 is overlapped above the lintel cross beam. Along the height direction DH of the lintel cross beam, the second connecting plate 50 is lower than the first connecting plate 40, and the first connecting plate 40 and the second connecting plate 50 are spaced apart along the first direction D1. The projection of the end of the second connecting plate 50 close to the first connecting plate 40 along the first direction D1 is a second convex edge 51 with a high middle and low sides. The projection of the end of the second connecting plate 50 away from the first connecting plate 40 along the first direction D1 is a second straight edge 52, and at least part of the second convex edge 51 is higher than the second straight edge 52. The lintel plate also includes a third connecting plate 60. The third connecting plate 60 is connected between the first connecting plate 40 and the second connecting plate 50, and the first connecting plate 40 and the second connecting plate 50 are located on different sides of the third connecting plate 60 along the thickness direction thereof. In this embodiment, part of the second connecting plate 50 is set to a configuration with a high middle and low sides, and the accumulated water can be drained from both sides of the box body. Since the first connecting plate 40 is higher than the second connecting plate 50, and a convex edge is provided at one end of the second connecting plate 50 close to the first connecting plate 40, a trend of decreasing height from the first connecting plate 40 to the second convex edge 51 and from the second convex edge 51 to the second straight edge 52 is formed. Therefore, the accumulated water will not gather at the end of the second connecting plate 50 close to the first connecting plate 40, eliminating the risk of the paint anti-corrosion life of the lintel plate and the quality risk of the trademark falling off due to water accumulation. In addition, the provision of the second straight edge 52 facilitates the connection of the lintel with other structures. Optionally, the first connecting plate 40, the second connecting plate 50, and the third connecting plate 60 are an integrally formed structure.

[0064] In some embodiments of the utility model, the second straight edge 52 is flush with the lowest height of the second convex edge 51. Exemplarily, the second connecting plate 50 has opposite first and second ends along the first direction D1, and opposite third and fourth ends along the second direction D2. The first end is connected to the third connecting plate 60. The projection of the first end along the first direction D1 is the second convex edge 51 with a high middle and low sides. The projection of the second end along the first direction D1 is the second straight edge 52. The middle of the first end is higher than the two sides, and the two sides of the first end are the third end and the fourth end. That is, the second end, the third end, and the fourth end are flush.

[0065] In some embodiments of the present invention, Figure 3 As shown, the height difference h between the middle and the two sides of the first convex edge 21 is 3-15 mm. The height difference of 3-15 mm can make the door lintel share the load more evenly when subjected to force, avoid local deformation or damage, and extend the service life of the door lintel.

[0066] In some embodiments of the present invention, the second flange 51 is in an arc shape or a broken line shape. The second flange 51 provides a connection structure with a high middle and low sides. The arc-shaped or broken line-shaped flange can more effectively guide water flow, prevent water from accumulating at the first end of the door lintel, and reduce the risk of damage that may be caused by water accumulation.

[0067] In some embodiments of the present invention, along the projection of the height direction DH, the first connecting plate 40 is staggered with the second connecting plate 50 , that is, the third connecting plate 60 is inclined to the vertical plane, so as to guide water to the second connecting plate 50 .

[0068] In some embodiments of the present invention, the first convex edge 21 is lower than the first straight edge 11. That is, the inner panel 20 is lower than the outer panel 10. Specifically, the projection of the inner panel 20 along the first direction D1 is located within the projection of the outer panel 10 along the first direction D1. When the lintel plate is overlapped to the lintel crossbeam, the third connecting plate 60 shows a tilting trend from the outer panel 10 to the inner panel 20, and from top to bottom. As the main force-bearing component, the outer panel 10 can withstand the weight and pressure of the upper cargo, thereby ensuring the structural stability of the lintel crossbeam. The lower height of the inner panel 20 makes the middle area of ​​the container roof lower, which can effectively reduce the squeezing force of the upper container or cargo on the lower container roof, helps to reduce the deformation and damage of the roof, and protects the integrity of the roof.

[0069] In some embodiments of the present invention, the size of the connecting member 30 along the second direction D2 is greater than the size of the outer plate 10 along the second direction D2, and the size of the connecting member 30 along the second direction D2 is greater than the size of the inner plate 20 along the second direction D2. At least one end of the connecting member 30 along the second direction D2 protrudes from the outer plate 10, and at least one end of the connecting member 30 along the second direction D2 protrudes from the inner plate 20. That is, a notch 31 is formed at the end of the lintel beam. The lintel beam is connected to the corner piece 70 through the notch 31 at the end. Optionally, the corner piece 70 is welded to the lintel beam and the lintel plate respectively.

[0070] In some embodiments of the present invention, reinforcing plates 80 are provided at both ends of the door lintel along the second direction D2. The reinforcing plates 80 are respectively welded to the door lintel corner pieces 70.

[0071] In some embodiments of the present invention, along the first direction D1, the connection between the first connecting plate 40 and the third connecting plate 60 is staggered from the first straight edge 11. Along the first direction D1, the connection between the second connecting plate 50 and the third connecting plate 60 is staggered from the first convex edge 21. That is, the connection between the lintel board and the lintel crossbeam avoids the corner of the lintel board.

[0072] Based on the above embodiments, Figure 5 As shown, along the first direction D1, the distance d between the connection between the second connecting plate 50 and the third connecting plate 60 and the first flange 21 is 3-5 mm, which avoids the weld connecting the R angle of the lintel plate and the top of the inner plate 20 on the R angle, eliminating poor welding quality.

[0073] Reference Figure 7 The utility model also provides a container, comprising the above-mentioned lintel. Along the first direction D1, the inner plate 20 of the lintel crossbeam is closer to the center of the box body than the outer plate 10. The second convex edge 51 of the lintel plate protrudes toward the top of the container. Thus, the accumulated water in the container can be drained along a preset path. By reducing the accumulated water and improving the structural stability, the service life of the entire container can be effectively extended.
