Description

Technical Field

[0001] This application relates to the field of container technology, and more specifically to a bottom side beam and a container having the bottom side beam. Background Technology

[0002] The bottom side beam is a longitudinal beam that connects the front and rear corner pieces at the bottom of the side wall of a container. It is an important structural component that bears the load of the cargo inside the container. In frame containers with incomplete superstructures and no side walls, the bottom side beam is usually an I-beam composed of upper flanges, lower flanges, and web plates welded together.

[0003] However, in existing frame-type containers, the upper flange of the bottom side beam extends beyond the container floor. Therefore, the existing I-beam structure of the bottom side beam has the following problems: 1) The inner side of the upper flange occupies part of the container's internal width space, reducing the applicable width range for loaded cargo; 2) When only the width of the upper flange is reduced to increase the internal width, the overall stability of the bottom side beam is weakened; 3) The bottom side beam can withstand uniformly distributed loads but cannot withstand large concentrated loads. For example, in integral sliding tarpaulin containers, the inner side of the bottom side beam is the space for loading cargo inside the container, while the outer side is the space for installing the tarpaulin system. Therefore, the bottom side beam needs to simultaneously meet the requirements of both spatial dimensions.

[0004] Therefore, a bottom side beam and a container with such a bottom side beam are needed to at least partially solve the above problems. Utility Model Content

[0005] The utility model description section introduces a series of simplified concepts, which will be further explained in detail in the detailed description section. This utility model description section is not intended to limit the key features and essential technical features of the claimed technical solution, nor is it intended to determine the scope of protection of the claimed technical solution.

[0006] To at least partially address the aforementioned problems, according to a first aspect of this application, a bottom side beam is provided for a container, the bottom side beam comprising: Upper wing panel; Lower wing panel; The web, the upper flange, the lower flange, and the web all extend along the length of the bottom side beam, with the upper end of the web connected to the upper flange and the lower end of the web connected to the lower flange; and A longitudinal angle steel extends along the length of the bottom side beam, with its upper end connected to the upper flange and its lower end connected to the outer surface of the web. The upper wing has a width smaller than the lower wing, the upper wing has a thickness greater than the lower wing, and the upper wing has a cross-sectional area greater than or equal to the lower wing.

[0007] According to the bottom side beam of this application, the width of the upper flange is smaller than the width of the lower flange, which increases the width of the cargo that can be loaded into the container and increases the internal volume of the container. The thickness of the upper flange is greater than the thickness of the lower flange, and the cross-sectional area of ​​the upper flange is greater than or equal to the cross-sectional area of ​​the lower flange. Therefore, when the width of the upper flange is reduced, the stability and strength of the bottom side beam do not decrease. Furthermore, by setting longitudinal angle steel, the stability and strength of the bottom side beam can be further improved.

[0030] This application provides a bottom side beam 100 and a container having the bottom side beam 100. The bottom side beam 100 of this application can be applied in maritime, rail, and road container transportation fields, and can also be extended to flatbed trucks, transport trailers, semi-trailers, curtain-side trucks, and box trucks. In one specific embodiment of this application, the container is an integral sliding tarpaulin type or a platform type container. Since sliding tarpaulin type and platform type containers are common structures in the art, only the bottom side beam 100 of the container will be described in detail.

[0031] like Figures 1 to 3 As shown, the sliding tarpaulin-type, rack-mounted container includes a base frame 220 and a sliding tarpaulin system 210. The base frame 220 is located at the bottom of the container, and the sliding tarpaulin system 210 is generally constructed in a U-shape to cover the sides and top of the container, with its two bottom ends connected to the sides of the base frame 220. Specifically, the base frame 220 includes a pair of bottom side beams 100 located on both sides of the bottom of the container. The bottom side beams 100 extend along the length of the container, and the pair of bottom side beams 100 are arranged parallel to each other. The two bottom ends of the sliding tarpaulin system 210 are connected to the outer sides of the bottom side beams 100. According to the integral sliding tarpaulin-type, rack-mounted container of this application, the upper structure of the container is incomplete, without side walls, therefore the internal width dimension W of the base frame 220 is relatively wider, and there is no lateral reinforcement structure, resulting in a wider range of widths for loading goods inside the container and a larger internal volume.

[0032] like Figure 1 , Figure 2 and Figure 4As shown, the bottom side beam 100 mainly includes an upper flange 110, a web 120, a lower flange 130, and a longitudinal angle steel 140. The upper flange 110, web 120, and lower flange 130 all extend along the length of the bottom side beam 100. The upper end of the web 120 is connected to the upper flange 110, and the lower end of the web 120 is connected to the lower flange 130. Specifically, the upper end of the web 120 is connected to the upper flange 110 near its inner surface, and the lower end of the web 120 is connected to the lower flange 130 approximately at its center. The longitudinal angle steel 140 extends along the length of the bottom side beam 100, and the upper end of the longitudinal angle steel 140 is connected to the upper flange 110, while the lower end of the longitudinal angle steel 140 is connected to the outer surface of the web 120 (i.e., the outer surface of the web 120). Figure 4 (The right side of the middle). Specifically, each of the pair of bottom side beams 100 is provided with a longitudinal angle steel 140.

[0033] It should be noted that in this application, the directional terms "outer" and "inner" are those directions determined based on the state in which the bottom side beam 100 is installed on the container. That is, "outer surface of the web 120" refers to the surface of the web 120 facing away from the inner side of the container when the bottom side beam 100 is installed on the container.

[0034] In this application, the width of the upper flange 110 is smaller than the width of the lower flange 130, which increases the width of the cargo that can be loaded into the container and increases the internal volume of the container. The thickness of the upper flange 110 is greater than the thickness of the lower flange 130, and the cross-sectional area of ​​the upper flange 110 is greater than or equal to the cross-sectional area of ​​the lower flange 130. Therefore, when the width of the upper flange 110 is reduced, the stability and strength of the bottom side beam 100 are not reduced. Furthermore, by providing longitudinal angle steel 140, the stability and strength of the bottom side beam 100 can be further improved.

[0035] Specifically, the outer surface of the upper wing plate 110 (i.e. Figure 4 The right side of the lower wing (i.e., the outer side of the lower wing 130) does not extend beyond the outer side of the lower wing 130. Figure 4 The right side of the upper wing 110, and the inner side of the upper wing 110 (i.e. Figure 4 The left side of the lower wing (i.e., the inner side of the lower wing 130) does not extend beyond the inner side of the lower wing 130. Figure 4 (Left side of the upper flange 110). Preferably, the inner side of the upper flange 110 is flush with the inner side of the web 120. Preferably, the inner side of the upper flange 110 extends a few millimeters beyond the inner side of the web 120.

[0036] like Figure 4 As shown, preferably, the sliding tarpaulin system 210 does not extend beyond the inner side of the upper wing 110, therefore the sliding tarpaulin system 210 does not occupy the internal space of the container. The underframe 220 also includes forklift slots 221 (see...). Figure 2This space is for use with forklifts. There are no vertical reinforcing ribs between the longitudinal angle steel 140 and the lower flange 130 and fork slot 221. This space can be used for the installation of the guide rail 211, V-rollers 212, and flange system mounting plate 213 of the sliding tarpaulin system 210, as well as for the sliding operation of the sliding tarpaulin system 210. The support rod 215 and brake device 216 of the sliding tarpaulin system 210 can be located above the upper flange 110.

[0037] like Figure 4 and Figure 5 As shown, the longitudinal angle steel 140 includes a vertical extension 141 and a transverse extension 143 connected to the vertical extension 141. The end of the vertical extension 141 is connected to the upper flange 110. The end of the transverse extension 143 is connected to the outer surface of the web 120. Specifically, the longitudinal angle steel 140 also includes a rounded corner 142, which connects the vertical extension 141 and the transverse extension 143. Figure 5 As shown, the guide rail 211 of the sliding tarpaulin system 210 is disposed on the outer side of the web 120 along the length direction of the bottom side beam 100, and the guide rail 211 is located below the transverse extension 143 of the longitudinal angle steel 140. The rollers 212 of the sliding tarpaulin system 210 are movably disposed on the guide rail 211 along the length direction of the guide rail 211, so that the tarpaulin of the sliding tarpaulin system 210 can be switched between an unfolded state and a stowed state.

[0038] Preferably, the included angle A between the vertical extension 141 and the horizontal extension 143 is less than 90°. Therefore, as... Figure 5 As shown, the bottom weld of the longitudinal angle steel 140 (i.e., the weld between the transverse extension 143 and the web 120) will not interfere with the guide rail 211, and the guide rail 211 and the longitudinal angle steel 140 can be installed without gaps to prevent impurities from entering.

[0039] like Figure 4 and Figure 5 As shown, the bottom side beam 100 also includes a reinforcing angle steel 150. The reinforcing angle steel 150 is located in the space enclosed by the longitudinal angle steel 140, the upper flange 110, and the web 120, and is in close contact with the longitudinal angle steel 140. Specifically, each of the pair of bottom side beams 100 is provided with a reinforcing angle steel 150. The cross-sectional structure of the reinforcing angle steel 150 is similar to that of the longitudinal angle steel 140, and the reinforcing angle steel is in close contact with the vertical extension 141 and the transverse extension 143.

[0040] Preferably, such as Figure 2As shown, the reinforcing angle steel 150 is located at the center of the longitudinal angle steel 140 along its length to resist the lateral stress and deformation generated when the base frame 220 is subjected to concentrated loads, thereby improving the overall stability of the base frame 220. According to the bottom side beam 100 of this application, the thickness, length, and material strength of the reinforcing angle steel 150 can be individually adjusted based on the stress calculated by mechanical analysis under the maximum concentrated load condition, while keeping other structural elements unchanged. Furthermore, multiple reinforcing angle steels 150 can be provided along the length of the bottom side beam 100 according to other working conditions.

[0041] Figure 1 This is a specific embodiment of the integral sliding tarpaulin-type, rack-mounted container of this application, which has no side walls or top structure. The sliding tarpaulin system 210 can be locked and sealed to both ends of the container for rain protection and can also be opened, and can slide between the two ends of the container along its length. Due to the presence of a braking device 216, the sliding tarpaulin system 210 can stop at any position. This type of container allows for loading and unloading of goods in the left, center, and right areas on both sides of the container and on the top of the container. Therefore, the integral sliding tarpaulin-type, rack-mounted container of this application is very convenient for loading, unloading, and transporting goods (especially dense, heavy-weight goods).
