Description

Technical Field

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

[0002] The side panels, top panels and front panels of containers are subject to less force and mainly serve the functions of shielding and sealing. Currently, the side panels, top panels and front panels of ordinary containers are all made of thin corrugated steel plates, which account for 40% - 50% of the total weight of the entire container. The problems existing in the production process of containers are as follows:

[0003] (1) There is a phenomenon of rust on the thin corrugated steel plates. In severe cases, the steel plates may even be rusted out of holes, and sandblasting, anti-corrosion coating, etc. are required. However, the anti-corrosion effect of the anti-corrosion coating will decay over time, and the service life is still very limited. In addition, anti-corrosion coating not only has a large workload, but also has sandblasting dust noise and coating pollution, and the working environment is poor;

[0004] (2) During the transportation and use of the container, the paint on the inner surface of the thin corrugated steel plate will fall off, especially when the coating comes into contact with the goods, resulting in the staining of the goods and polluting the goods inside the container;

[0005] (3) The thin corrugated steel plate has poor heat insulation performance. When the container is transported from domestic to tropical regions such as Southeast Asia or there is a large diurnal temperature difference change, condensation is likely to occur inside the container, causing the goods to get damp, which has a great impact on some goods that need to be kept dry, such as grains;

[0006] (4) Welding is usually used between the thin corrugated steel plates and between the thin corrugated steel plates and the main components of the container. The welding volume is large, and 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. And when replacing the thin corrugated steel plate with other materials, there may be problems such as insufficient box strength, poor sealing performance or poor waterproof performance.

[0007] Therefore, a modular container is needed to at least partially solve the above problems. Summary of the Utility Model

The other material plates are metal plates, such as corrugated plates. Exemplarily, as Figure 4 shown, the top plate 20 includes a composite material plate 70 and a metal plate 71. The metal plate 71 is connected to the composite material plate 70 by a reinforcing rib 50. Alternatively, the metal plate 71 and the composite material plate 70 overlap each other, and the overlapping portion is connected by a fastener 60 or a structural adhesive. The composite material plate makes the top plate have the advantages of light weight, high strength, good wear resistance, etc., while the metal plate makes the top plate have the advantage of large stiffness and can effectively reduce the production cost of the top plate.

[0109] 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. Further improve the wear resistance, corrosion resistance and impact resistance of the container at the box surface, and effectively reduce the maintenance cost during the life cycle of the container.

[0110] The position of the reinforcing rib 50 on the composite material plate 70 is related to the desired strength of the side plate 10, the top plate 20 or the front plate 30. The reinforcing rib 50 can be provided at the joint of two adjacent composite material plates 70 (see Figure 11 ), or can be provided at a non-joint of a single composite material (see Figure 6a ). Exemplarily, at least one of the side plate 10, the top plate 20 and the front plate 30 includes at least two spliced composite material plates 70. A single composite material plate 70 is independently provided with at least one reinforcing rib 50 to strengthen the composite material plate 70 at the non-joint. The reinforcing rib is provided at the non-joint of the composite material plate, and the position of the reinforcing rib is arranged based on the desired physical properties of the container box surface, and is not limited by the size of a single composite material plate.

[0111] As Figure 11As shown, two adjacent composite material plates 70 are close to each other and there are no other components between them. Further, the entire reinforcing rib 50 is located on one side of the composite material plate 70. The two adjacent composite material plates 70 are connected by the reinforcing rib 50, so as to connect and strengthen the composite material plate 70 at the splicing joint. There is a small installation gap between the two spliced composite material plates, and it is easy to form a seal at the splicing joint, improving the sealing performance. For the solution where the reinforcing rib is on the outer side of the composite material plate, only the composite material plate forms the inner surface of the box body at the splicing joint. There are no other components contacting the goods inside the box at the splicing joint, but the composite material plate contacts the goods, and the wear-resistant performance of the composite material can be fully utilized.

[0112] As Figure 6a and Figure 6b shown, the reinforcing rib 50 includes a connecting portion 50A and a protruding portion 50B. Among them, the connecting portion 50A is connected to the composite material plate 70, and the protruding portion 50B extends from the connecting portion 50A in a direction away from the composite material plate 70. Thus, multiple composite material plates 70 can be spliced through the reinforcing rib 50. At the splicing joint of the composite material plates 70, the reinforcing rib 50 can ensure the watertightness and structural strength of the modular container 100.

[0113] A single door panel 131 is composed of at least one composite material plate 70. Optionally, a single door panel 131 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 door frame 132 is connected to the outer surface of the composite material plate 70 through fasteners 60 such as screws and / or structural adhesives.

[0114] The modular container 100 according to the present application can reduce the weight of the container 100, which is beneficial to realizing the lightweight of the modular container 100; ensure the structural strength, stiffness and watertightness of the container 100; and can greatly reduce the workloads such as welding, sandblasting and anti-corrosion spraying and reduce the painting area during the manufacturing process of the modular container 100. This not only simplifies the process flow, shortens the production cycle, but also avoids the adverse effects of welding fumes, welding slag, etc. on the physical health of personnel and the environment, and has a low recycling cost. The modular container 100 of the present application has the advantages of being green, low-carbon, lightweight, environmentally friendly, reliable and durable.

[0115] The following will describe the settings of the composite material plate 70 and the reinforcing rib 50 on the box body frame 101 in conjunction with Figure 2 , Figure 5 , Figures 7 - 8 , Figure 10 .

[0116] As Figure 2 and Figure 5As shown, the reinforcing rib 50 includes a side plate reinforcing rib 51 extending vertically between the top side beam 108 and the underframe 109. The side plate reinforcing rib 51 is connected to the composite material plate 70 that forms the side plate 10. The side plate 10 is located inside the box frame 101, so that the composite material plate 70 that forms at least a part of the side plate 10 is located inside the box frame 101. Further, the composite material plate 70 that forms at least a part of the side plate 10 is located on the side facing the inside of the container 100 of the front corner post 42, the rear corner post 41, the top side beam 108, and the underframe 109. The side plate reinforcing rib 51 is provided on the outer side of the composite material plate 70 that forms the side plate 10. Therefore, the reinforcing rib 50 is separated from the inside of the container 100 by the composite material plate 70 that forms the side plate 10, and the reinforcing rib 50 is not exposed inside the container 100, and the inner surface of the side plate 10 formed by the composite material plate 70 is flat. The composite material plate 70 that forms the side plate 10 can be in direct contact with the goods inside the box to make full use of the wear-resistant performance of the composite material.

[0117] As Figure 2 , Figure 7 and Figure 8 shown, the reinforcing rib 50 further includes a top plate reinforcing rib 52 extending horizontally between a pair of top side beams 108. The top plate reinforcing rib 52 is connected to the composite material plate 70 that forms the top plate 20. The top plate 20 is located outside the box frame 101, so that the composite material plate 70 that forms at least a part of the top plate 20 is located outside the box frame 101. Further, the composite material plate 70 that forms at least a part of the top plate 20 is located on the upper side facing away from the inside of the container 100 of a pair of top side beams 108, the front header 106, and the rear header 107. The top plate reinforcing rib 52 is located on the outer side of the composite material plate 70 that forms the top plate 20. Therefore, the reinforcing rib 50 is separated from the inside of the container 100 by the composite material plate 70 that forms the top plate 20, and the reinforcing rib 50 is not 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.

[0118] Optionally, as Figure 7 shown, the top plate reinforcing rib 52 is provided at the end of the front header 106. The top plate reinforcing rib 52 is connected to both the composite material plate 70 that forms the top plate 20 and the end of the front header 106 through the fastener 60. The top plate reinforcing rib 52 is provided at the end of the rear header 107. The top plate reinforcing rib 52 is connected to both the composite material plate 70 that forms the top plate 20 and the end of the rear header 107 through the fastener 60. With this arrangement, the top plate reinforcing rib 52 can improve the connection strength between the front header 106 and the rear header 107 and the top plate 20, making the structural strength better. As Figure 8As shown, both ends of the top plate stiffener 52 can extend to the top side beams 108 located on both sides of the box frame 101. The top plate stiffener 52 is connected to the top plate 20 and the top side beam 108 through fasteners 60. With such an arrangement, the top plate stiffener 52 can improve the connection strength between the top side beam 108 and the top plate 20, making the structural strength better.

[0119] As Figure 2 shown, the stiffener 50 further includes a front plate stiffener 53 vertically extending between the front sill 113 and the chassis 109. The front plate stiffener 53 is connected to the composite material plate 70 that constitutes the front plate 30. The front plate 30 is located inside the box frame 101, so that at least a part of the composite material plate 70 that constitutes the front plate 30 is located inside the box frame 101. Further, at least a part of the composite material plate 70 that constitutes the front plate 30 is located on the side facing the inside of the container 100 of the front header 106, the front sill 113, and the chassis 109. The front plate stiffener 53 is located outside the composite material plate 70 that constitutes the front plate 30. Therefore, the stiffener 50 is separated from the inside of the container 100 by the composite material plate 70 that constitutes the front plate 30, and the stiffener 50 is not 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 constitutes 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.

[0120] As Figure 2 , Figure 10 and Figure 20 shown, the stiffener 50 further includes a door panel stiffener 55 provided on the door frame 132. The door panel stiffener 55 is connected to the composite material plate 70 that constitutes the door panel 131. The door panel stiffener 55 is horizontally arranged, specifically, it extends along the width direction of the door panel assembly 130, and its two ends are connected to or abutted against the door vertical beams 135 of the door frame 132. The door frame 132 and the door panel stiffener 55 are located outside the composite material plate 70 that constitutes the door panel 131. Therefore, the stiffener 50 is separated from the inside of the container 100 by the composite material plate 70 that constitutes the door panel 131, and the stiffener 50 is not 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 that constitutes the door panel 131 can be in direct contact with the goods inside the box to make full use of the wear-resistant performance of the composite material.

[0121] To better prevent water from entering the box from the installation position of the top plate stiffener 52, the top plate stiffener 52 is selected to have a closed structure. Specifically, the cross-section of the top plate stiffener 52 is in the shape of a circular closed ring to form a cavity 56, and sealing members 57 are provided at both ends of the top plate stiffener 52 (see Figure 8 ). The outer ends of the fasteners 60 are hidden in the cavity 56 of the top plate stiffener 52.

[0122] The door lock mechanism 133 includes a lock rod 136, a lock rod bracket 137, a handle 138, and a handle base 139. The lock rod 136 is vertically arranged, and mounting positions for installing and fixing the lock rod bracket 137 are provided on the door panel reinforcing rib 55 and / or the door frame 132. The lock rod 136 is installed on the door frame 132 and / or the door panel reinforcing rib 55 through lock rod brackets 137 at different positions. For example, the lock rod bracket 137 can be connected to the door frame 132 and / or the door panel reinforcing rib 55 respectively by suitable means such as welding or connection with fasteners 60 such as screws. An optional example is that the end of the handle 138 is pivotally connected to the lock rod 136, and the handle base 139 can be fixed to the door panel reinforcing rib 55 by welding or fasteners 60 such as screws, and the handle 138 is rotatably and detachably locked on the handle base 139.

[0123] By providing the door panel reinforcing rib 55, on the one hand, the strength of the composite material plate 70 can be enhanced, and on the other hand, it is convenient to fix the lock rod 136 and the handle base 139 on the door panel reinforcing rib 55. In other words, the door panel reinforcing rib 55 can improve the structural strength of the door panel while also providing fixing positions for the lock rod 136 and the handle base 139. In addition, the door panel reinforcing rib 55 is arranged along the width direction of the door panel assembly 130, and the lock rod 136 is vertically arranged and installed on the door panel reinforcing rib 55, improving the anti-deformation ability of the middle position of the door panel 131 in the horizontal and vertical directions.

[0124] Preferably, the composite material plate 70 constitutes the entire panel of the side plate 10, the top plate 20, and the front plate 30. Further, the composite material plate 70 constituting the side plate 10, the top plate 20, and the front plate 30 is an integral composite material plate 70. Thus, the number of connection points can be reduced, the manufacturing can be made simpler, and the outer surface of the top plate 20 can be made flat, effectively improving the load-bearing performance, and the inner surfaces of the side plate 10 and the front plate 30 can be made flat, making full use of the wear-resistant performance of the composite material.

[0125] The specific structure of the reinforcing rib 50 will be described below.

[0126] The reinforcing rib 50 includes at least one connecting portion 50A and a protruding portion 50B. The connecting portion 50A is connected to the composite material plate 70, and the protruding portion 50B extends from the connecting portion 50A in a direction away from the composite material plate 70. The reinforcing rib 50 has a certain structural strength and can provide a supporting force for the composite material plate 70 to strengthen the structure.

[0127] As Figure 11As shown, when two adjacent composite material plates 70 are coplanar with each other, the connecting portion 50A is in contact with and connected to both of the adjacent composite material plates 70. The connecting portion 50A at least partially covers the seam 80 between the two adjacent composite material plates 70, and preferably covers the entire seam 80. The protruding portion 50B is connected to the connecting portion 50A at at least one end in the width direction of the reinforcing rib 50, and the connecting portion 50A is connected to the protruding portion 50B at at least one end in the width direction of the reinforcing rib 50. The protruding portion 50B and the connecting portion are connected at the end, so that the reinforcing rib 50 can be manufactured by bending the plate, and the manufacturing is simple.

[0128] The protruding portion 50B includes a first protruding portion 50B1 and a second protruding portion 50B2. The second protruding portion 50B2 is connected to the first protruding portion 50B1 and is spaced apart from the connecting portion 50A in the thickness direction of the reinforcing rib 50. 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. Both ends of the second protruding portion 50B2 are respectively connected to the connecting portion 50A via the first protruding portion 50B1. 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.

[0129] Return to refer Figures 6a - 6b 、 Figure 9 , a concave structure 54 is formed inside the protruding portion 50B. Further, the inside of the two spaced-apart first protruding portions 50B1 and the second protruding portion 50B2 connected to the two first protruding portions 50B1 constitutes the concave structure 54. With such a setting, the reinforcing rib 50 can have better structural strength, stiffness and product economy.

[0130] When the connection method of the fastener 60 is adopted, since the fastener 60 needs to penetrate through the reinforcing rib 50 and the composite material plate 70, the water outside the box can easily enter the box from the perforation of the fastener 60. For this reason, the present application adopts a hidden design for the fastener 60.

[0131] The fastener 60 at the reinforcing rib 50 is hiddenly designed.

[0132] The connecting portion 50A includes a first connecting portion 50A1 disposed within the recessed structure 54. The fastener 60 connects the composite material plate 70 to the first connecting portion 50A1 such that the outer end portion of the fastener 60 is hidden within the recessed structure 54. Optionally, the connecting portion 50A further includes a second connecting portion 50A2 disposed outside the recessed structure 54. The second connecting portion 50A2 is bonded to the composite material plate 70 by structural adhesive or sealant. Both portions of the connecting portion are connected to the composite material plate, resulting in better connection reliability between the reinforcing rib and the composite material plate.

[0133] One example is, as Figure 9 and Figure 11 shown, 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 to 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.

[0134] Another example is, as Figure 12 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 the protruding portion 50B at both ends in the width direction of the reinforcing rib 50. The first connecting portion 50A1 is connected to the composite material plate 70 by the fastener 60, and the two second connecting portions 50A2 are both bonded to the composite material plate 70.

[0135] Yet another example is, as Figure 6a and Figure 13 shown, the connecting portion 50A includes two first connecting portions 50A1 and does not include a second connecting portion 50A2. The two first connecting portions 50A1 are respectively connected to the protruding portion 50B at both ends in the width direction of the reinforcing rib 50. The fastener 60 connects the two first connecting portions 50A1 to the composite material plate 70. The difference is that Figure 6a the first protruding portion 50B1 in Figure 13 is perpendicular to the first connecting portion 50A1,

[0136] The fastener 60 is disposed on the first connecting portion 50A1 such that the outer end portion of the fastener 60 can be hidden within the recessed structure 54 and blocked by the protruding portion 50B. Thereby, it is possible to further prevent water outside the box from entering the box through the fastener holes at 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.

[0137] The fastener 60 at the box frame 101 is designed to be hidden.

[0138] The box members of the box frame 101 include an inner side plate 141, an outer side plate 142, and a transition plate 143 connected between the inner side plate 141 and the outer side plate 142. The outer side plate 142 is located on the outer side of the inner side plate 141 facing away from the center of the box frame 101 and blocks the inner side plate 141. The outer side plate 142, the inner side plate 141, and the transition plate 143 form a cavity 140 for the installation of the fastener 60 and for increasing the structural strength. The inner side plate 141 is connected to the composite material plate 70 by the fastener 60 so that the outer end portion of the fastener 60 is hidden within the cavity 140.

[0139] As Figures 14 to 17 shown, the transition plate 143 extends inward from the end of the outer side plate 142, such that the transition plate 143 and the outer side plate 142 are easily formed into an integral member, facilitating production and manufacturing. The inner side plate 141 is at least connected to the transition plate 143. For example, one end of the inner side plate 141 is connected to the transition plate 143, and the other end is connected to the outer side plate 142. Alternatively, one end of the inner side plate 141 is connected to the transition plate 143, and the other end is a free end and is spaced apart from the outer side plate 142.

[0140] The outer side plate and the transition plate 143 are integrally formed, and the inner side plate 141 is a separate member and is welded or bonded to at least the transition plate 143 (see Figures 14 to 16 ). This solution can independently produce and manufacture the inner side plate 141, so the structure of the desired inner side plate 141 can be correspondingly designed according to the structure of the box frame 101 at different positions, and the applicability is better. Alternatively, the inner side plate 141, the outer side plate 142, and the transition plate 143 are integrally formed (see Figure 17 ). This solution can avoid welding or bonding, so the assembly steps of the container can be reduced and the assembly efficiency can be improved.

[0141] The cross-section of the cavity 140 forms a closed annular shape (see Figures 14 to 16 ), such that the overall structure forming the cavity 140 has better strength. 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 side plate (see Figure 17) Thus, the concave cavity 140 can be formed by bending the plate material, making production and manufacturing easier.

[0142] The inner side plate 141 includes the corner post inner side plate 144. The front corner post 42 and / or the rear corner post 41 include the corner post main body 45 as the outer side plate 142 and the corner post transition plate 145 as the transition plate 143. The corner post transition plate 145 extends inwards from the end of the corner post main body 45. The corner post inner side plate 144 is located inside the corner post main body 45 and is at least connected to the corner post transition plate 145. The composite material plate 70 constituting the side plate 10 and / or the front plate 30 is connected to the corner post inner side plate 144 through the fastener 60. One end of the corner post inner side plate 144 is connected to the corner post transition plate 145, and the other end thereof extends towards the inner surface of the corner post main body 45 and is connected or abutted to the inner surface of the corner post main body 45.

[0143] Specifically, as Figure 14 shown, the front corner post 42 includes the corner post main body 45, the first corner post transition plate 145a, and the second corner post transition plate 145b. The first corner post transition plate 145a extends inwards from the end of the corner post main body 45 in the length direction of the box body frame 101. The second corner post transition plate 145b extends inwards from the end of the corner post main body 45 in the width direction of the box body frame 101. The corner post inner side plate 144 located inside the front corner post 42 is configured as two split members, namely the first corner post inner side plate 144a and the second corner post inner side plate 144b, to be respectively connected to the composite material plates 70 constituting the side plate 10 and the front plate 30. The first corner post inner side plate 143 is connected to at least the first transition plate 145a. The composite material plate 70 constituting the side plate 10 is connected to the first corner post inner side plate 144a through the fastener 60. The second corner post inner side plate 144b is connected to at least the second corner post transition plate 145b. The composite material plate 70 constituting the front plate 30 is connected to the second corner post inner side plate 144b through the fastener 60. Alternatively, the corner post inner side 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 constituting the side plate 10 and the front plate 30.

[0144] As Figure 15 shown, the rear corner post 41 includes the corner post main body 45 and the third corner post transition plate 145c. The third corner post transition plate 145c extends inwards from the end of the corner post main body 45 in the length direction of the box body frame 101. The corner post inner side plate 144 includes the third corner post inner side plate 144c located inside the rear corner post 41. The third corner post inner side plate 144c is connected to at least the third corner post transition plate 145c. The composite material plate 70 constituting the side plate 10 is connected to the third corner post inner side plate 144c through the fastener 60.

[0145] As Figure 16As shown, the inner panel 141 includes a side beam inner panel 146a located inside the top side beam 108. The top side beam 108 includes a side beam main body 116 as the outer panel 142 and a side beam transition panel 146b as the transition panel 143. The side beam transition panel 146b extends inwards from the lower end of the side beam main body 116. The side beam inner panel 146a is connected to at least the side beam transition panel 146b. The composite material panel 70 forming the side panel 10 is connected to the side beam inner panel 146a by fasteners 60. The side beam main body 116 is configured to be bent outwards in multiple sections to form a concave platform 117. The concave platform 117 includes a first section 117a arranged horizontally and a second section 117b arranged vertically. The side beam transition panel 146b extends inwards from the second section 117b. The side beam inner panel 146a is located between the first section 117a and the side beam transition panel 146b and is connected to both of them.

[0146] As Figure 17 shown, the inner panel 141 includes an end lintel inner panel 147a located inside the front lintel 106. The front lintel 106 includes an end lintel main body 125 as the outer panel 142 and an end lintel transition panel 147b as the transition panel 143. The end lintel transition panel 147b extends inwards from the lower end of the end lintel main body 125. The end lintel inner panel 147a is connected to at least the end lintel transition panel 147b. Figure 11 It is shown that one end of the end lintel inner panel 147a is connected to the end lintel transition panel 147b, and the other end is a free end. The composite material panel 70 forming the front panel 30 is connected to the end lintel inner panel 147a by fasteners 60.

[0147] The fasteners 60 are arranged on the inner panel 141 of the box frame 101 such that the outer ends of the fasteners 60 can be hidden in the cavity 140 formed by the inner panel 141, the outer panel 142, and the transition panel 143. Thus, it is possible to further prevent water outside the box from entering the box through the fastener holes at the box frame 101, effectively reducing the risk of water entering the box and improving the sealing and waterproof performance of the box; and the fasteners 60 blocked by the outer panel 142 cannot be observed from the outside of the container 100, which can improve the overall aesthetics of the product.

[0148] As Figure 18 shown, two adjacent composite material panels 70 overlap each other, and the overlapping part is connected by fasteners 60 or structural adhesive. Specifically, the overlapping part is separately connected by fasteners 60 or structural adhesive, the overlapping part and a first connecting part 50A1 of the reinforcing rib 50 are connected together by fasteners 60, and the non-overlapping part and another first connecting part 50A1 of the reinforcing rib 50 are connected by fasteners 60. Fixing the overlapping two composite material panels 70 not only can improve the structural strength of the composite material panels 70 at the splicing joint, but also can prevent water outside the box from entering the box through the joint 80, effectively reducing the risk of water entering the box and improving the waterproof performance of the box.

[0149] A seal is provided between the composite material plate 70 and the box body frame 101, and between the composite material plate 70 and the reinforcing rib 50. By providing the seal, water outside the box can be prevented from entering the box through the gaps between the composite material plate 70 and the box body frame 101 and between the composite material plate 70 and the reinforcing rib 50, effectively reducing the risk of water entering the box. The seal can be composed of sealant and seals such as tapes. Specifically, seals are formed by sealant or seals at the joints 80 between the composite material plates 70, at the riveted and / or bolted joints between the composite material plate 70 and the box body frame 101, and at the riveted and / or bolted joints between the composite material plate 70 and the reinforcing rib 50 to ensure the overall watertightness of the combined container 100.

[0150] The mating surfaces of the composite material plates 70 that form the side plates 10 with the box body frame 101 and the reinforcing ribs 50 are in substantially the same plane (see Figure 5 ). The mating surfaces of the composite material plates 70 that form the top plate 20 with the box body frame 101 and the reinforcing ribs 50 are in substantially the same plane (see Figure 7 ). The mating surfaces of the composite material plates 70 that form the front plate 30 with the box body frame 101 and the reinforcing ribs 50 are in substantially the same plane (see Figure 5 ). The mating surfaces of the composite material plates 70 that form the door panels with the door frame 132 and the reinforcing ribs 50 are in the same plane. Thus, the composite material plate 70 can be fitted to the corresponding parts of the box body frame 101 or the door frame and each of the reinforcing ribs 50. The seal is provided between the mating surfaces of the composite material plate 70 and the reinforcing rib 50 with each other. And the seal is provided between the mating surfaces of the composite material plate 70 and the box body frame 101 with each other, or between the mating surfaces of the composite material plate 70 and the door frame with each other. When there are adjacent composite material plates 70 and the two adjacent composite material plates 70 overlap, the seal can be provided between the mating surfaces of the two adjacent composite material plates 70 at the overlapping part. Providing the seal on the mating surfaces results in a larger sealing range and a better sealing effect, thus more effectively preventing water outside the box from entering the box.

[0151] The seal is provided around the fastener 60. Specifically, in the area where the composite material plate 70 is connected to the box body frame 101 by the fastener 60, the seal is provided close to the fastener 60 and on the inner side close to the center of the box and the outer side away from the center of the box of the fastener 60, thus forming a double-sided seal. By setting it like this, water can be blocked from entering the box through the holes for the fastener 60 to pass through and the gaps between the composite material plate 70 and the box body frame 101, more effectively improving the water leakage prevention performance of the container 100. In the area where the composite material plate 70 is connected to the reinforcing rib 50 by the fastener 60, the seal surrounds the fastener 60.

[0152] The reinforcing rib 50 of the present application is made of a plate. The thickness, arrangement spacing, geometric structure, material, etc. of the reinforcing rib 50, as well as the thickness, material, etc. of the composite material plate 70 are factors affecting the physical properties of the container 100 at each box surface. The physical properties include structural strength, stiffness, equivalent stress, elastic deformation amount, etc. The thickness and arrangement spacing of the reinforcing rib 50 will be discussed below. It should be noted that the "box surface" refers to the side plate 10, top plate 20, front plate 30, and door panel 131 that form the internal space of the container.

[0153] Considering the different force requirements of the container 100 at each box surface, the thickness and arrangement spacing of the reinforcing rib 50 are set differently at each box surface. Usually, the side plate 10 and the front plate 30 need to bear greater forces due to being easily in contact with goods and being easily squeezed by goods. The top plate 20 is not easily squeezed by goods, so it requires a smaller force than the front plate 30 and the side plate 10.

[0154] Exemplarily, the spacing D11 between two adjacent side plate reinforcing ribs 51 (see Figure 2 ) can be 300 mm to 600 mm; for example, D11 is 300 mm, 320 mm, 340 mm, 360 mm, 380 mm, 400 mm, 420 mm, 440 mm, 460 mm, 480 mm, 500 mm, 520 mm, 540 mm, 560 mm, 580 mm, 600 mm and other suitable values. The thickness t11 of the plate used to make the side plate reinforcing rib 51 (see Figure 6a ) can be 2.5 mm to 4 mm; for example, t11 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 suitable values.

[0155] The spacing D12 between two adjacent top plate reinforcing ribs 52 (see Figure 2 ) can be 500 mm to 800 mm; for example, D12 is 500 mm, 520 mm, 540 mm, 560 mm, 580 mm, 600 mm, 620 mm, 640 mm, 660 mm, 680 mm, 700 mm, 720 mm, 740 mm, 770 mm, 780 mm, 800 mm and other suitable values. The thickness t12 of the plate used to make the top plate reinforcing rib 52 (see Figure 9 ) can be 2 mm to 3 mm; for example, t12 is 2 mm, 2.1 mm, 2.2 mm, 2.3 mm, 2.4 mm, 2.5 mm, 2.6 mm, 2.7 mm, 2.8 mm, 2.9 mm, 3 mm and other suitable values.

[0156] The spacing D13 between two adjacent front plate reinforcing ribs 53 (see Figure 2) can be from 300 mm to 600 mm; for example, D13 can be suitable values such as 300 mm, 320 mm, 340 mm, 360 mm, 380 mm, 400 mm, 420 mm, 440 mm, 460 mm, 480 mm, 500 mm, 520 mm, 540 mm, 560 mm, 580 mm, 600 mm, etc. The thickness t13 of the plate used to make the front panel stiffener 53 (see Figure 6b ) can be from 2.5 mm to 4 mm; for example, t13 can be suitable values such as 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, etc.

[0157] The thickness t14 of the plate used to make the door panel stiffener 55 is from 2.5 mm to 4 mm; for example, t14 can be suitable values such as 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, etc.

[0158] It should be noted that the spacing and thickness of the above-mentioned stiffeners 50 are applicable to containers of different sizes, such as 20-foot containers, 40-foot containers, 40-foot high-cube containers, etc., and are applicable to containers 100 in which at least one of the side panels 10, top panels 20, and front panels 30 is made of a composite material panel 70.

[0159] Optionally, the spacing between adjacent side panel stiffeners 51 and corner posts 40 is the same as or similar to the spacing between two adjacent side panel stiffeners 51. Exemplarily, the spacing between adjacent side panel stiffeners 51 and corner posts 40 is slightly greater than the spacing between two adjacent side panel stiffeners 51. The spacing between adjacent front panel stiffeners 53 and corner posts 40 is the same as or similar to the spacing between two adjacent front panel stiffeners 53. Exemplarily, the spacing between adjacent front panel stiffeners 53 and corner posts 40 is slightly greater than the spacing between two adjacent front panel stiffeners 53. The spacing between adjacent top panel stiffeners 52 and end sills is the same as or similar to the spacing between two adjacent top panel stiffeners 52. Exemplarily, the spacing between adjacent top panel stiffeners 52 and corner posts 40 is slightly greater than the spacing between two adjacent top panel stiffeners 52.

[0160] The plate of the stiffener 50 is preferably high-strength steel with a yield strength of 345 MPa or more. The thickness t2 of the composite material panel 70 (see Figure 5) can be from 2.5 mm to 4 mm; for example, suitable values of t2 are 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, etc. Thus, the composite material board itself has a certain anti-deformation ability and anti-impact ability. The material of the composite material board 70 is a known composite material or the composite material provided by this application. The material of the composite material board 70 is preferably a known composite material with a tensile strength of 248 MPa or more. In order to both reduce the weight of the container 100 and effectively increase the structural strength of the top plate 20, the front plate 30, and the side plate 10, the composite material board 70 is preferably made of at least one of continuous fiber-reinforced thermoplastic composites, thermosetting fiber-reinforced composites, and thermoplastic glass steel plates. Specifically, the known composite materials mainly include glass fibers and resins.

[0161] Selecting the various parameters of this application from the above ranges can ensure that the physical properties such as the structural strength and stiffness of the container 100 can reach the expected level of container strength while using the least amount of materials, including composite materials, reinforcing ribs, etc., reducing material consumption and reducing the weight of the container.

[0162] The spacing of the fasteners 60 is different at different positions. As Figure 19 shown, the fasteners 60 include a first fastener 61 and a second fastener 62. It should be noted that, as described above, the fasteners 60 on the box body frame 101 and the reinforcing rib 50 are blocked by the protruding portion 50B, Figure 19 which schematically shows the outer transmission positions of the first fastener 61 and the second fastener 62. The composite material board 70 is connected to the box body frame 101 through the first fastener 61, and the composite material board 70 constituting the front plate 30 and / or the side plate 10 is connected to the reinforcing rib 50 through the second fastener 62. There is a spacing D31 between two adjacent first fasteners 61, and there is a spacing D32 between two adjacent second fasteners 62. The connection between the composite material board 70 and the box body frame 101 needs to be more firm and reliable, so D31 < D32. Optionally, the spacing D31 is from 80 mm to 180 mm; for example, suitable values of D31 are 80 mm, 100 mm, 110 mm, 120 mm, 130 mm, 140 mm, 150 mm, 160 mm, 180 mm, etc. The spacing D32 is from 120 mm to 300 mm; for example, suitable values of D32 are 120 mm, 160 mm, 180 mm, 200 mm, 220 mm, 240 mm, 260 mm, 280 mm, 300 mm, etc. Setting the spacing of the fasteners within the above ranges can ensure a reliable connection between the composite material board and the box body frame and the reinforcing rib, and resist the deformation of the composite material board.

[0163] As Figure 20As shown, the fastener 60 further includes a third fastener 63 and a fourth fastener 64. It should be noted that, as described above, the fasteners 60 on the gantry 132 and the door panel reinforcing rib 50 are blocked by the protruding portion 50B. Figure 20 The outer transmission positions of the third fastener 63 and the fourth fastener 64 are schematically shown. The gantry 132 is connected to the composite material plate 70 through the third fastener 63, and the door panel reinforcing rib 50 is connected to the composite material plate 70 through the fourth fastener 64. The adjacent two third fasteners 63 have a spacing D33, and the adjacent two fourth fasteners 64 have a spacing D34. Since the connection between the composite material plate 70 and the gantry 132 needs to be more firm and reliable, the third fasteners 63 are arranged more densely relative to the fourth fasteners 64, and at this time D34 > D33. If necessary and / or desirable, it can also be set to D34 ≤ D33. Optionally, the spacing D33 is 50 mm to 120 mm, for example, D33 is 50 mm, 55 mm, 60 mm, 65 mm, 70 mm, 75 mm, 80 mm, 85 mm, 90 mm, 100 mm, 110 mm, 120 mm and other appropriate values. The spacing D34 is 80 mm to 170 mm, for example, D34 is 80 mm, 100 mm, 110 mm, 120 mm, 130 mm, 140 mm, 150 mm, 160 mm, 170 mm and other appropriate values. Setting the spacing of the fasteners 60 within the above range can ensure the reliable connection between the composite material plate 70 and the gantry 132 and the door panel reinforcing rib 50, and resist the deformation of the composite material plate 70.

[0164] Return to participate Figure 3 , an avoidance hole 11 is provided in a portion of the side plate 10 near the bottom side. Specifically, a fixing member 118 for auxiliary fixing is provided in the concave structure on the inner side of the reinforcing rib 50. The fixing member 118 can pass through rope-like members such as binding ropes and steel wires or connecting members such as connecting hooks and buckles to assist in fixing the goods in the box. The avoidance hole 11 is used to fix the end of a rope-like member such as a rope to the fixing member 118 at the bottom of the side plate 10, so as to fix the goods with the rope-like member. Optionally, the shape of the fixing member 118 is columnar, ring-shaped, etc. The fixing member 118 can be welded to the reinforcing rib 50 and / or the bottom side beam 112. The protruding portion 50B of the reinforcing rib 50 forms a concave structure 54, and the fixing member 118 is located in the concave structure 54. The fixing member 118 is provided at the bottom of the reinforcing rib 50. Optionally, the container further includes a fixing assembly corresponding to each fixing member. The fixing assembly includes a cover plate and two sealing plates provided on both sides of the fixing member. One end of the fixing member is fixedly connected to the bottom side beam and the other end is fixedly connected to the cover plate. The cover plate, the two sealing plates and the inner wall of the protruding portion enclose a space for guiding an external member to pass through the fixing member.

[0165] The present application can achieve at least the following beneficial effects:

[0166] This application uses composite material plates to replace thin corrugated steel plates to construct side plates, top plates, front plates, and / or door plates. The composite material plates are non-metallic material plates, which can avoid rusting and holes caused by rusting, greatly extend the service life, and can be anti-corrosive without using paint and without using welding. That is to say, the composite material plates have the characteristics of being weld-free and paint-free, so it can greatly reduce the workload of welding and spraying during the production of containers, reduce the emissions of VOCs and solid waste, and have obvious environmental protection benefits.

[0167] Since the density of the composite material is much lower than that of steel, compared with a steel container of the same box type, the composite material container of this application can theoretically reduce the weight of the container by more than 6% and reduce carbon emissions by more than 13%. At the same time, due to the excellent wear resistance, corrosion resistance, and impact resistance of the composite material, the maintenance cost during the life cycle of the container can be effectively reduced.

[0168] The inner surface of the container of this application is flat, which is conducive to the shipment of goods and improving the biosecurity level of the container. There is no paint on the inner surface of the box surface, which can avoid pollution such as cargo staining caused by paint dropping. In addition, compared with steel plates, the composite material plates have better heat insulation, which can avoid problems such as moisture caused by condensation inside the box body, so as to facilitate the cross-regional transportation and use of containers in tropical regions around the world such as Southeast Asia.
