Abstract
Description
Technical Field
[0001] The utility model generally relates to the technical field of container structures, and more specifically to a bottom cross beam and a container. Background Art
[0002] As a tool for logistics transportation, containers have been widely used. With the different types of goods and usage areas, some special containers have been derived. Currently, some special containers adopt a relatively low underframe, so that the height of the bottom cross beam is smaller than that of a general maritime container. In order to enable the relatively short bottom cross beam to meet the corresponding strength requirements, the bottom cross beam is usually designed into a special shape such as an H shape (also known as an I shape).
[0003] Please refer to Figure 1 and Figure 2 , the existing container 1 has a bottom side beam 21 and a floor 22. The end of the bottom cross beam 11 is connected to the bottom side beam 21, and the floor 22 is laid on the top surface of the bottom cross beam 11. The H-shaped bottom cross beam 11 is composed of three parts: an upper wing plate 12, a web 14, and a lower wing plate 13. Usually, the three independent workpieces of the upper wing plate 12, the web 14, and the lower wing plate 13 are welded together to form a whole. Since welding requires special welding production lines and equipment to complete, the required investment is very large; in addition, there will inevitably be some forming defects of the weld beads 11a after the bottom cross beam 11 is welded, and welding deformations such as side bending and twisting will occur, affecting the product quality of the container.

[0063] The present utility model provides a bottom cross beam.
[0064] First Embodiment
[0065] Please refer to Figure 3 and Figure 4, the bottom crossbeam 111 is for the container 1. The container 1 includes a bottom side beam 21 and a floor 22. The bottom crossbeam 111 extends along the width direction DW of the container 1. It should be noted that the bottom crossbeam 111 is preferably constructed as an integrally formed workpiece, which can be formed by bending, molding, rolling, etc. It is easy to process, and the quality can be well guaranteed. There are no defects and deformations caused by welding, reducing the manufacturing difficulty and cost, and improving the forming quality of the workpiece. In addition to the aforementioned forming methods, for example, using a mold can also achieve the integral forming of the bottom crossbeam 111, reducing the manufacturing difficulty and cost. In other words, the forming defects and deformations of the bottom crossbeam 111 are also avoided in the processing technology. Specifically, the bottom crossbeam 111 includes an upper flange 112, a lower flange 113, and a web 114. The upper flange 112 is connected to the bottom side beam 21, and the top surface of the upper flange 112 is used to support the floor 22. The lower flange 113 is located below the upper flange 112 and is connected to the bottom side beam 21. The web 114 is located between the upper flange 112 and the lower flange 113, and both ends of the web 114 are respectively connected to the upper flange 112 and the lower flange 113. Along the length direction DL of the container 1, the upper flange 112 and the lower flange 113 are located on both sides of the web 114. Further, the web 114 includes an intermediate section 114a, and the intermediate section 114a is inclined relative to the vertical direction DH and the length direction DL of the container 1.
[0066] According to the bottom crossbeam 111 of the present utility model, the intermediate section 114a of the web 114 is inclined relative to the vertical direction DH and the length direction DL of the container 1, so that the bottom crossbeam 111 has excellent compressive and torsional strength. When used on the container 1, it can improve the quality of the container 1 to a certain extent.
[0067] The following explains that the upper flange 112 and the lower flange 113 are located on both sides of the web 114: The web 114 has a first side and a second side spaced along the length direction DL of the container 1. For example, the first side is located above the second side. Please refer to Figure 3 , along the length direction DL of the container 1, one end of the upper flange 112 is connected to the first side, and the other end of the upper flange 112 extends along the length direction DL of the container 1 towards a position closer to the second side. One end of the lower flange 113 is connected to the second side, and the other end of the lower flange 113 extends along the length direction DL of the container 1 towards a position closer to the first side. Figure 3 In, the cross-section of the bottom crossbeam 111 is generally S-shaped. Or rather, if the bottom crossbeam 111 in Figure 3 is rotated half a week around the vertical direction DH, the cross-section of the bottom crossbeam 111 is generally Z-shaped.
[0068] Please continue to refer to Figure 3, along the length direction DL of the container 1, the dimension W1 of the upper flange 112 ranges from 20 ≤ W1 ≤ 100 mm, for example, 20 mm, 30 mm, 40 mm, 50 mm, 60 mm, 70 mm, 80 mm, 90 mm, 100 mm. Along the length direction DL of the container 1, the dimension W2 of the lower flange 113 ranges from 20 ≤ W2 ≤ 100 mm, for example, 20 mm, 30 mm, 40 mm, 50 mm, 60 mm, 70 mm, 80 mm, 90 mm, 100 mm. Preferably, along the length direction DL of the container 1, the dimension W1 of the upper flange 112 ranges from 40 ≤ W1 ≤ 60 mm, for example, 40 mm, 45 mm, 50 mm, 55 mm, 60 mm, and the dimension structure of the lower flange 113 is the same as that of the upper flange 112, that is, W2 = W1.
[0069] The belly edge 114 further includes a first connecting section 114b and a second connecting section 114c. The two ends of the first connecting section 114b are respectively connected to the middle section 114a and the upper flange 112, and the first connecting section 114b does not protrude upward beyond the upper flange 112. The two ends of the second connecting section 114c are respectively connected to the middle section 114a and the lower flange 113, and the second connecting section 114c does not protrude downward beyond the lower flange 113. Preferably, the cross-sections of the first connecting section 114b and the second connecting section 114c are configured as circular arcs (as Figure 3 shown). And, along the vertical direction DH, the top edge of the first connecting section 114b is flush with the top surface of the upper flange 112, and the bottom edge of the second connecting section 114c is flush with the bottom surface of the lower flange 113. In other words, the top surface and the bottom surface of the bottom cross member 111 are both configured as flat surfaces to facilitate the installation and connection with other components. Further, along the vertical direction DH, the dimension H of the bottom cross member 111 ranges from 30 ≤ H ≤ 200 mm, for example, 30 mm, 50 mm, 100 mm, 150 mm, 200 mm. It should be noted that the dimension of the bottom cross member 111 with this structure along the vertical direction DH is smaller than that of the bottom cross member in the prior art. Under the condition of ensuring sufficient strength, the bottom cross member 111 with this structure can further reduce the height of the container chassis, thereby increasing the height dimension inside the container body.
[0070] Please refer to Figure 5 , one end of the upper flange 112 away from the first connecting section 114b has a first flanging 112a that slopes downward relative to the upper flange 112 so as not to affect the installation connection between the upper flange 112 and the floor 22. Please refer to Figure 6 , one end of the lower flange 113 away from the second connecting section 114c has a second flanging 113a that slopes downward relative to the lower flange 113. Alternatively, please refer to Figure 7, one end of the lower wing edge 113 away from the second connecting section 114c has a second flanging 113a that slopes upward relative to the lower wing edge 113.
[0071] Please refer to Figure 8 , one end of the upper wing edge 112 away from the first connecting section 114b has a first flanging 112a that protrudes downward relative to the upper wing edge 112, and the first flanging 112a is folded onto the upper wing edge 112. One end of the lower wing edge 113 away from the second connecting section 114c has a second flanging 113a that protrudes upward relative to the lower wing edge 113, and the second flanging 113a is folded onto the lower wing edge 113. Alternatively, please refer to Figure 9 , and Figure 8 The difference from Figure 10 is that one end of the lower wing edge 113 away from the second connecting section 114c has a second flanging 113a that protrudes downward relative to the lower wing edge 113, and the second flanging 113a is folded onto the lower wing edge 113. Figure 11 In Figure 9 and Figure 10 , the following explains the aforementioned "folding" and "rolling" with respect to the upper wing edge 112 and the first flanging 112a: In the state where the first flanging 112a is folded onto the upper wing edge 112, along the vertical direction DH, the first flanging 112a is in contact with the upper wing edge 112, or rather, there is no gap or basically no gap between the first flanging 112a and the upper wing edge 112. In the state where the first flanging 112a is rolled onto the upper wing edge 112, along the vertical direction DH, only one side edge of the first flanging 112a abuts against the upper wing edge 112, or rather, there is a gap between the first flanging 112a and the upper wing edge 112.
[0072] Return to refer to Figure 3 , Figures 5 to 7 , preferably, along the length direction DL of the container 1, the outermost edge of one end of the upper wing edge 112 away from the belly edge 114 is flush with one outermost edge of the belly edge 114, and correspondingly, the outermost edge of one end of the lower wing edge 113 away from the belly edge 114 is flush with the other outermost edge of the belly edge 114. With such a setting, it is beneficial for the installation and positioning of the bottom cross beam 111 along the vertical direction DH.
[0073] Second Embodiment
[0074] Please refer to Figure 12 and Figure 13, the abdominal edge 214 includes an upper wing edge 212, a lower wing edge 213, and the abdominal edge 214, and the abdominal edge 214 includes an intermediate section 214a that is inclined relative to the vertical direction and the length direction DL of the container 1. Compared with Figure 3 , the difference is that the abdominal edge 214 further includes a third connecting section 214d and a fourth connecting section 214e. Specifically, the third connecting section 214d is perpendicular to the upper wing edge 212, and both ends of the third connecting section 214d are respectively connected to the first connecting section 214b and the intermediate section 214a. The fourth connecting section 214e is perpendicular to the lower wing edge 213, and both ends of the fourth connecting section 214e are respectively connected to the second connecting section 214c and the intermediate section 214a. In an unshown embodiment, only one of the third connecting section 214d and the fourth connecting section 214e may be included. And, Figure 12 , along the length direction DL of the container 1, the outermost edge of the abdominal edge 214 protrudes outward from the outermost edges of the upper wing edge 212 and the lower wing edge 213. In other words, along the length direction DL of the container 1, the outermost edges of the ends of the upper wing edge 212 and the lower wing edge 213 that are away from the abdominal edge 214 do not protrude outward from the outermost edge of the abdominal edge 214.
[0075] Please refer to Figure 14 , one end of the upper wing edge 212 that is away from the first connecting section 214b has a first flanging 212a that is inclined downward relative to the upper wing edge 212, so as not to affect the installation connection between the upper wing edge 212 and the floor 22. Please refer to Figure 15 , one end of the lower wing edge 213 that is away from the second connecting section 214c has a second flanging 213a that is inclined downward relative to the lower wing edge 213. Alternatively, please refer to Figure 16 , one end of the lower wing edge 213 that is away from the second connecting section 214c has a second flanging 213a that is inclined upward relative to the lower wing edge 213.
[0076] In addition, the present utility model further provides a container 1, and the container 1 includes the aforementioned bottom cross member 111 and / or bottom cross member 211. Those skilled in the art know that the container 1 includes a box body, and the box body has a door end. It can be understood that the bottom cross member belongs to the chassis part of the container 1. It should be noted that in the state where the aforementioned bottom cross member is connected to the box body, along the length direction DL of the container 1, the connection between the upper wing edge and the abdominal edge of the same bottom cross member is closer to the door end than the connection between the lower wing edge and the abdominal edge, so as to provide greater strength support when the container 1 is loaded and unloaded.
[0077] According to the bottom cross member of the present utility model, the bottom cross member can be formed by bending, molding, rolling, etc., is easy to process, and the quality can be well guaranteed.
