Description

Technical Field

[0001] This application relates to the technical field of containers, and more particularly to a container. Background Art

[0002] The side plates, top plates and front plates of containers are subject to less force and mainly serve the functions of shielding and sealing. Currently, the side plates, top plates and front plates of ordinary containers are all made of thin corrugated steel plates. There are two main problems in the production process of containers: firstly, operations such as sandblasting and anti-corrosion painting of thin corrugated steel plates not only involve a large amount of work, but also generate sandblasting dust noise and painting pollution, resulting in a poor working environment; secondly, welding is used between thin corrugated steel plates and between thin corrugated steel plates and the main components of the container, with a large amount of welding. Welding fumes, harmful gases, noise, radiation, etc. during the welding process will also have an adverse impact on the environment and the physical health of personnel. Therefore, it is necessary to use non-metallic material plates to replace thin corrugated steel plates to solve the above problems. When using non-metallic material plates, rivets are usually used to connect non-metallic material plates to other box body components, and welding cannot be used to eliminate the gaps at the connection positions, resulting in poor waterproof performance of the box body.

[0003] Therefore, a container is needed to at least partially solve the above problems. Summary of the Utility Model

[0087] The container 100 according to the present application can be a 20-foot container, a 40-foot container, a 40-foot high-cube container, a 45-foot high-cube container, or a railway wide-body container, etc. The dimensions of the container 100 are not specifically limited herein.

[0088] The container 100 further includes at least one composite material panel 70 and at least one container member 80. The composite material panel 70 constitutes at least a part of the side panel 10, the top panel 20, the front panel 30, and / or the door panel 131. The composite material panel 70 is connected to other container members 80 through fasteners 60.

The outer end of the fastener 60 can be accommodated at the cavity 140, and the fastener 60 is hidden by the outer part 142. Thus, water outside the container can be prevented from entering the container through the fastener holes at the connection between the composite material panel 70 and the container member 80, effectively reducing the risk of water entering the container and improving the sealing and waterproof performance of the container. And the fastener 60 cannot be observed from the outside of the container, which can improve the overall aesthetics of the product.

[0091] In some embodiments, the container 100 includes at least one reinforcing rib 50, and the reinforcing rib 50 is the above-mentioned box body member 80. The reinforcing rib 50 is disposed outside the composite material plate 70 and connected to the composite material plate 70 to strengthen the strength of the side plate 10, the top plate 20, and / or the front plate 30 formed by the composite material plate 70. The composite material plate 70 may be a flat plate. The reinforcing rib 50 may be disposed at the splicing joint of two adjacent composite material plates 70 or at the non-splicing joint of a single composite material.

[0092] Exemplarily, at least a part of the side plate 10, the top plate 20, the front plate 30, and the door panel 131 are made of the composite material plate 70. In the illustrated embodiment, all of the side plates 10, all of the top plates 20, all of the front plates 30, and all of the door panels 131 are made of the composite material plate 70, thus forming a container with five composite material plates for the box surfaces. Alternatively, the door panel 131 may be made of other materials, such as a thin corrugated metal plate, thus forming a container with four composite material plates for the box surfaces.

[0093] Optionally, all of the side plates 10 are composed of at least two composite material plates 70; alternatively, all of the side plates 10 are composed of one composite material plate 70. All of the top plates 20 are composed of at least two composite material plates 70; alternatively, all of the top plates 20 are composed of one composite material plate 70. All of the front plates 30 are composed of at least two composite material plates 70; alternatively, all of the front plates 30 are composed of one composite material plate 70. This further improves the wear resistance, corrosion resistance, and impact resistance of the container at the box surface and effectively reduces the maintenance cost during the life cycle of the container.

[0094] A single door panel 10 is composed of at least one composite material plate 70. Optionally, a single door panel 10 is composed of one composite material plate 70. The composite material plate 70 has an inner surface facing the inside of the container and an outer surface opposite to the inner surface.

The top plate 20 is located outside the box frame 101, so that the composite material plate 70 that forms the top plate 20 is located outside the box frame 101. The top plate reinforcing rib 52 is located outside the composite material plate 70 that forms the top plate 20. Therefore, the reinforcing rib 50 is separated from the interior of the container 100 by the composite material plate 70 that forms the top plate 20, the reinforcing rib 50 will not be exposed inside the container 100, and the inner surface of the top plate 20 formed by the composite material plate 70 is flat. The composite material plate 70 that forms the top plate 20 can be in direct contact with the goods inside the box to make full use of the wear-resistant performance of the composite material. Alternatively, the top plate reinforcing rib 52 is located inside the composite material plate 70 that forms the top plate 20. Therefore, the outer surface of the top plate 20 formed by the composite material plate 70 is flat, which is beneficial for rainwater and the like to flow down from the top plate 20 without water accumulation. In this alternative, the top plate reinforcing rib 52 is bonded to the composite material plate 70 that forms the top plate 20 by structural adhesive.

[0098] The reinforcing rib 50 also includes a front plate reinforcing rib 53 that extends vertically between the front sill 113 and the front header 106, and the front plate reinforcing rib 53 is connected to the composite material plate 70 that forms the front plate 30. The front plate 30 is located inside the box frame 101, so that the composite material plate 70 that forms the front plate 30 is located inside the box frame 101. The front plate reinforcing rib 53 is located outside the composite material plate 70 that forms the front plate 30. Therefore, the reinforcing rib 50 is separated from the interior of the container 100 by the composite material plate 70 that forms the front plate 30, the reinforcing rib 50 will not be exposed inside the container 100, and the inner surface of the front plate 30 formed by the composite material plate 70 is flat. The composite material plate 70 that forms the front plate 30 can be in direct contact with the goods inside the box to make full use of the wear-resistant performance of the composite material.

The door panel reinforcing rib 55 is horizontally arranged, and both ends thereof are connected to or abutted against the gantry 132. The gantry 132 and the door panel reinforcing rib 55 are located outside the composite material plate 70 constituting the door panel 131. Therefore, the reinforcing rib 50 is isolated from the inside of the container 100 by the composite material plate 70 constituting the door panel 131, and the reinforcing rib 50 will not be exposed inside the container 100, and the inner surface of the door panel 131 formed by the composite material plate 70 is flat. The composite material plate 70 constituting the door panel 131 can be in direct contact with the goods in the box to make full use of the wear-resistant performance of the composite material.

[0100] The reinforcing rib 50 and the composite material plate 70 are fixedly connected by a combination of fasteners 60 such as rivets and bolts, structural adhesives or various methods. The composite material plate 70 and the box body frame 101 are fixedly connected by a combination of fasteners 60 such as rivets and bolts, structural adhesives or various methods. Thus, welding of the composite material plate can be avoided, the welding workload during the production of the container can be greatly reduced, and the emissions of VOCs (Volatile Organic Compounds) and solid waste can be effectively reduced, ensuring the friendliness to operators and the environment.

[0101] The plate of the reinforcing rib 50 is preferably a high-strength steel with a yield strength of 345 MPa or more. The thickness t2 of the composite material plate 70 (see Figure 5 ) can be 2.5 mm to 4 mm; for example, t2 is 2.5 mm, 2.6 mm, 2.8 mm, 3 mm, 3.2 mm, 3.4 mm, 3.6 mm, 3.8 mm, 4 mm and other appropriate values. Thus, the composite material plate itself has a certain anti-deformation ability and anti-impact ability. The material of the composite material plate 70 is a known composite material or the composite material provided in the present application. The material of the composite material plate 70 is preferably a known composite material with a tensile strength of 248 MPa or more. The composite material plate 70 can be made of at least one of continuous fiber reinforced thermoplastic composite materials, thermosetting fiber reinforced composite materials and thermoplastic glass steel plates.

[0102] When the connection method of the fastener 60 is adopted, since the fastener 60 needs to penetrate the reinforcing rib 50 and the composite material plate 70, it is very easy for water outside the box to enter the box from the perforation of the fastener 60. Therefore, the present application adopts a hidden design for the fastener 60.

[0103] The fastener 60 at the reinforcing rib 50 is hiddenly designed.

[0104] Such as Figures 4 to 7As shown, the reinforcing rib 50 includes a connecting portion 50A serving as the inner portion 141 described above, two first protruding portions 50B1 serving as the transition portion 143, and a second protruding portion 50B2 serving as the outer portion 142. Among them, the connecting portion 50A is attached to and connected to the composite material plate 70. The first protruding portions 50B1 and the second protruding portion 50B2 constitute the protruding portion 50B of the reinforcing rib 50, and the protruding portion 50B protrudes in a direction away from the interior space of the container with respect to the connecting portion 50A.

[0105] The second protruding portion 50B2 is spaced apart from the connecting portion 50A in the thickness direction of the reinforcing rib 50. The two ends of the second protruding portion 50B2 in the width direction of the reinforcing rib 50 are respectively connected to the connecting portion 50A via the corresponding first protruding portions 50B1. The first protruding portion 50B1 is inclined or perpendicular to the connecting portion 50A. The second protruding portion 50B2 is parallel to the connecting portion 50A. The two protruding portions with different extending directions make the geometric structure strength of the reinforcing rib better. The first protruding portion 50B1, the second protruding portion 50B2, and the connecting portion 50A are integrally formed to form an integral member, or the second protruding portion 50B2 and the first protruding portion 50B1 are integrally formed to form an integral member. Thereby, the connection of the reinforcing rib 50 is simplified, and the structural strength is ensured.

[0106] A concave structure 54 serving as the cavity 140 is formed on the inner sides of the first protruding portion 50B1 and the second protruding portion 50B2. The connecting portion 50A includes a first connecting portion 50A1 facing the concave structure 54. The fastener 60 connects the composite material plate 70 and the first connecting portion 50A1 so that the outer end portion of the fastener 60 is hidden in the concave structure 54. Optionally, the connecting portion 50A further includes a second connecting portion 50A2 provided outside the concave structure 54. The second connecting portion 50A2 is bonded to the composite material plate 70 by structural adhesive or sealant. The two parts of the connecting portion are both connected to the composite material plate, making the connection reliability between the reinforcing rib and the composite material plate better.

[0107] One example is, as Figure 4 shown, the connecting portion, the first protruding portion, the second protruding portion, and another first protruding portion are sequentially connected end to end to form a closed annular structure. Specifically, the connecting portion 50A includes a first connecting portion 50A1 and does not include a second connecting portion 50A2; the first connecting portion 50A1 is connected to the protruding portion 50B at both ends in the width direction of the reinforcing rib 50. The fastener 60 connects the first connecting portion 50A1 and the composite material plate 70. The cross-sectional shape of the reinforcing rib 50 is, for example, rectangular. Alternatively, the connecting portion 50A in this example may further include at least one second connecting portion 50A2.

[0108] Another example is, as Figure 5As shown, the connecting portion 50A includes a first connecting portion 50A1 and two second connecting portions 50A2 connected to the first connecting portion 50A1. The two second connecting portions 50A2 are respectively connected to two ends of the two first protruding portions 50B1 in the width direction of the reinforcing rib 50. The first connecting portion 50A1 is connected to the composite material plate 70 through a fastener 60, and the two second connecting portions 50A2 are both bonded to the composite material plate 70.

[0109] Another example is, as Figure 6 and Figure 7 shown, the connecting portion 50A includes two first connecting portions 50A1 and does not include the second connecting portion 50A2. The two first connecting portions 50A1 are arranged at intervals and are respectively connected to the inner sides of the two first protruding portions 50B1. The fastener 60 connects the two first connecting portions 50A1 to the composite material plate 70. The difference is that Figure 6 the first protruding portion 50B1 in Figure 7 is perpendicular to the first connecting portion 50A1, Figure 7 while the first protruding portion 50B1 in

[0110] is inclined to the first connecting portion 50A1. Alternatively, the connecting portion 50A in this example may further include at least one second connecting portion 50A2.

[0110] The fastener 60 is arranged on the first connecting portion 50A1 so that the outer end portion of the fastener 60 can be hidden in the recessed structure 54 and is blocked by the protruding portion 50B. Thus, it is possible to further prevent water outside the box from entering the box through the fastener holes at the composite material plate 70 and the reinforcing rib 50, effectively reducing the risk of water entering the box and improving the sealing and waterproof performance of the box; and the fastener 60 at the reinforcing rib 50 cannot be observed from the outside of the container 100, which can improve the overall aesthetics of the product.

[0111] A hidden design for the fastener 60 at the box frame 101.

[0112] As Figures 8 to 11 shown, for the box member 80 on the box frame 101, the transition portion 143 extends inward from the end of the outer side portion 142, so that the transition portion 143 and the outer side portion 142 are easily formed into an integral member, which is convenient for production and manufacturing. The inner side portion 141 is at least connected to the transition portion 143. For example, one end portion of the inner side portion 141 is connected to the transition portion 143, and the other end portion is connected to the outer side portion 142. Alternatively, one end portion of the inner side portion 141 is connected to the transition portion 143, and the other end portion is a free end and is spaced apart from the outer side portion 142.

[0113] The outer side portion and the transition portion 143 are integrally formed, and the inner side portion 141 is a separate member and is welded or bonded to at least the transition portion 143 (see Figures 8 to 10)。This solution can independently manufacture the inner part 141, so the structure of the desired inner part 141 can be correspondingly designed according to the structure of the box frame 101 at different positions, with better applicability. Alternatively, the inner part 141, the outer part 142, and the transition part 143 are integrally formed (see Figure 11 and Figure 12 ). This solution can avoid welding or bonding, so the assembly steps of the container can be reduced and the assembly efficiency can be improved.

[0114] The cross-section of the cavity 140 forms a closed annular shape (see Figures 8 to 10 、 Figure 12 ), making the overall structure of the cavity 140 stronger. Alternatively, the cross-section of the cavity 140 forms a groove shape with an opening, and the opening faces the inner surface of the outer part (see Figure 11 and Figure 12 ). Thus, the cavity 140 can be formed by bending the member, and the production and manufacturing are easier.

[0115] The inner part 141 includes an inner side plate 144 of the corner post. The front corner post 42 and / or the rear corner post 41 include a corner post main body 45 as the outer part 142 and a corner post transition plate 145 as the transition part 143.

The composite material plate 70 constituting the side plate 10 and / or the front plate 30 is connected to the inner side plate 144 of the corner post through a fastener 60. One end of the inner side plate 144 of the corner post is connected to the corner post transition plate 145, and the other end thereof extends toward the inner surface of the corner post main body 45 and is connected or abutted against the inner surface of the corner post main body 45.

[0116] Specifically, as Figure 8As shown, the front corner post 42 includes a corner post main body 45, a first corner post transition plate 145a, and a second corner post transition plate 145b. The first corner post transition plate 145a extends inward from the end of the corner post main body 45 in the length direction of the box frame 101. The second corner post transition plate 145b extends inward from the end of the corner post main body 45 in the width direction of the box frame 101. The corner post inner plate 144 located inside the front corner post 42 is configured as two split members, namely a first corner post inner plate 144a and a second corner post inner plate 144b, to be respectively connected to the composite material plates 70 forming the side plate 10 and the front plate 30. The first corner post inner plate 144a is connected to at least the first transition plate 145a. The composite material plate 70 forming the side plate 10 is connected to the first corner post inner plate 144a by a fastener 60. The second corner post inner plate 144b is connected to at least the second corner post transition plate 145b. The composite material plate 70 forming the front plate 30 is connected to the second corner post inner plate 144b by a fastener 60. Alternatively, the corner post inner plate 144 located inside the front corner post 42 is configured as an independent member to be simultaneously connected to the composite material plates 70 forming the side plate 10 and the front plate 30.

[0117] As Figure 9 shown, the rear corner post 41 includes a corner post main body 45 and a third corner post transition plate 145c. The third corner post transition plate 145c extends inward from the end of the corner post main body 45 in the length direction of the box frame 101. The corner post inner plate 144 includes a third corner post inner plate 144c located inside the rear corner post 41. The third corner post inner plate 144c is connected to at least the third corner post transition plate 145c. The composite material plate 70 forming the side plate 10 is connected to the third corner post inner plate 144c by a fastener 60.

[0118] As Figure 10 shown, the inner part 141 includes a side beam inner plate 146a located inside the top side beam 108. The top side beam 108 includes a side beam main body 116 as the outer part 142 and a side beam transition plate 146b as the transition part 143. The side beam transition plate 146b extends inward from the lower end of the side beam main body 116. The side beam inner plate 146a is connected to at least the side beam transition plate 146b. The composite material plate 70 forming the side plate 10 is connected to the side beam inner plate 146a by a fastener 60. The side beam main body 116 is configured to be bent outward in multiple segments to form a concave platform 117. The concave platform 117 includes a first segment 117a arranged horizontally and a second segment 117b arranged vertically. The side beam transition plate 146b extends inward from the second segment 117b. The side beam inner plate 146a is located between the first segment 117a and the side beam transition plate 146b and is connected to both of them.

[0119] As Figure 11As shown, the inner part 141 includes the end lintel inner plate 147a located inside the front lintel 106. The front lintel 106 includes the lintel main body 125 as the outer part 142 and the lintel transition plate 147b as the transition part 143. The lintel transition plate 147b extends inward from the lower end of the lintel main body 125. The end lintel inner plate 147a is connected to at least the lintel transition plate 147b. Figure 11 One end of the end lintel inner plate 147a is shown connected to the lintel transition plate 147b, and the other end is a free end. The composite material plate 70 forming the front plate 30 is connected to the end lintel inner plate 147a through the fastener 60.

[0120] As Figure 12 As shown, the top side beam 108 and / or the front lintel 106 can be made of a profiled square tube. The profiled square tube includes the outer tube wall 148 as the outer part 142, the inner tube wall 149 as the inner part 141, and the bottom tube wall 150 as the transition plate 143. The inner tube wall 149 is configured to be bent outward in multiple segments to form a concave platform 117.
