[0020] Flat rack containers can transport goods such as construction machinery and vehicles. However, in order to meet the load-bearing requirements, these containers are generally designed to be quite heavy. This results in low loading and unloading efficiency, and the containers themselves occupy a significant portion of the transport vehicle's load capacity, reducing the vehicle's cargo capacity and increasing transportation costs.

[0021] Based on this, this application provides a frame box 10. The frame box 10 includes a base 1 and a side frame 2. The side frame 2 is disposed at at least one end of the base 1 along a first direction. The side frame 2 includes a side plate 211. The side plate 211 is provided with a first through hole 2111 penetrating through the side plate 211. The base 1 includes a support beam 11, a fixing component 12, and a second connector 13. The two ends of the support beam 11 are disposed at the two ends of the base 1 along the first direction. The support beam 11 has a plurality of supports spaced apart along a second direction, which is perpendicular to the first direction. The support beam 11 is provided with a mounting cavity 111. The support beam is a fiber-reinforced resin composite beam, which ensures the supporting strength of the base 1, while reducing the weight of the base 1, reducing energy consumption during the transportation of the frame box 10, improving the loading and unloading efficiency of the frame box 10, saving costs, and the support beam 11 has the advantage of corrosion resistance and can adapt to high-salt and high-humidity environments. The fixing component 12 is disposed in the mounting cavity 111 and located at the end of the support beam 11. The fixing component 12 includes a fixing member 121 and a first connecting member 122. The first connecting member 122 is embedded in the fixing member 121 and is an integral part of the fixing member 121. The outer surface of the fixing member 121 is bonded to the inner surface of the support beam 11. The second connecting member 13 passes through the first through hole 2111 and is inserted into the first connecting member 122 and fixedly connected to the first connecting member 122. The second connecting member 13 fixes the side plate 211 to the first connecting member 122, so that the locking force of the second connecting member 13 is borne by the fixing component 12, and the stress is evenly transferred to the inner wall of the support beam 11 through the adhesive layer. This effectively avoids the composite material damage and stress concentration problems caused by directly tapping the composite material beam, thereby achieving a high-rigidity and high-strength connection while maximizing the structural integrity and load-bearing efficiency of the composite material beam, and ensuring the effective connection between the side plate 211 and the composite material.

[0022] The frame box 10 proposed in this application will be described in detail below with reference to the accompanying drawings.

[0023] One embodiment of this application discloses a frame box 10. (See reference...) Figure 1 The frame container 10 includes a base 1. The base 1 is used to support goods. The base 1 is located at the bottom of the frame container 10.

[0024] refer to Figure 1 , Figure 2 and Figure 3 The frame box 10 includes side frames 2. The side frames 2 are located at at least one end of the base 1 along a first direction. The side frames 2 include side plates 211. The side plates 211 can extend along a second direction, which is perpendicular to the first direction. The side plates 211 have a first through hole 2111. The first through hole 2111 penetrates the side plates 211. The first direction can be the length direction of the frame box 10. The first direction can be parallel to the horizontal direction. The material of the side plates 211 can be steel. Each side frame 2 has at least one side plate 211.

[0025] refer to Figure 3 , Figure 4 and Figure 5 The base 1 includes a support beam 11. The two ends of the support beam 11 are located at two ends of the base 1 along a first direction. The support beam 11 has a plurality of beams spaced apart along a second direction. The support beam 11 has a mounting cavity 111 within it. Specifically, there may be twelve support beams 11.

[0026] The support beam 11 is a fiber-reinforced resin composite beam. Using fiber-reinforced resin composite material for the support beam 11 ensures the supporting strength of the base 1, while reducing the weight of the base 1, decreasing energy consumption during the transportation of the frame box 10, improving the loading and unloading efficiency of the frame box 10, and saving costs. Furthermore, the support beam 11 has the advantage of corrosion resistance and can adapt to high-salt and high-humidity environments. Specifically, the fiber-reinforced resin composite material can be glass fiber reinforced resin composite material.

[0027] refer to Figure 3 , Figure 4 and Figure 5 The base 1 includes a fixing component 12. The fixing component 12 is disposed within the mounting cavity 111. The fixing component 12 is located at the end of the support beam 11. The fixing component 12 includes a fixing member 121. The fixing component 12 includes a first connecting member 122. The first connecting member 122 is embedded within the fixing member 121, and the first connecting member 122 and the fixing member 121 are integral. The outer surface of the fixing member 121 is bonded to the inner surface of the support beam 11. Specifically, the outer surface of the fixing member 121 and the inner surface of the support beam 11 are bonded with structural adhesive, and an adhesive layer is formed between the outer surface of the fixing member 121 and the inner surface of the support beam 11.

[0028] refer to Figure 3 , Figure 4 and Figure 5 The base 1 includes a second connector 13. The second connector 13 passes through the first through hole 2111. The second connector 13 is inserted into the first connector 122, and the second connector 13 and the first connector 122 are fixedly connected. The second connector 13 fixes the side plate 211 to the first connector 122. The first connector 122 is made of steel. The second connector 13 is made of steel.

[0029] In this application, the side frame 2 includes a side plate 211, and the base 1 includes a fixing component 12 and a second connector 13. The fixing component 12 includes a fixing member 121 and a first connector 122. The first connector 122 is embedded in the fixing member 121, and the first connector 122 and the fixing member 121 are integral parts. The outer side of the fixing member 121 is bonded to the inner side of the support beam 11. The locking force of the second connector 13 is borne by the fixing component 12, and the stress is evenly transferred to the inner wall of the support beam 11 through the adhesive layer. This effectively avoids the composite material damage and stress concentration problems caused by directly tapping the composite material beam. Thus, while achieving a high-rigidity and high-strength connection, the structural integrity and load-bearing efficiency of the composite material beam are maintained to the greatest extent, ensuring the effective connection between the side plate 211 and the composite material.

[0030] In one embodiment, reference Figure 1 , Figure 2 and Figure 3 The base 1 has side frames 2 at both ends along the first direction. The mounting cavity 111 extends through the support beam 11 along the extension direction of the support beam 11. The mounting cavity 111 has fixing components 12 at both ends. Both ends of each support beam 11 are connected to the side plate 211 through the fixing components 12 and connectors, so that both ends of the support beam 11 can be effectively connected to the side frame 2.

[0031] In one embodiment, the second connector 13 is threadedly connected to the first connector 122, providing a secure connection and saving costs. Specifically, the first connector 122 has a threaded hole, and the second connector 13 has a threaded shaft, such that the threaded shaft is inserted into the threaded hole and the second connector 13 is threadedly connected to the first connector 122. The second connector 13 can be a bolt.

[0032] The second connector 13 is welded to the side plate 211, which can prevent the second connector 13 from coming out of the first connector 122 and improve the stability of the connection between the side plate 211 and the fixing assembly 12.

[0033] In one embodiment, the support beam 11 is a beam formed by thermosetting pultrusion of fiber-reinforced resin composite material. Manufacturing fiber-reinforced resin composite beams using thermosetting pultrusion fully leverages the core advantages of lightweight and high strength of composite materials. This allows the support beam 11 to achieve extremely high strength and stiffness while weighing significantly less than steel, greatly facilitating transportation and installation. The thermosetting pultrusion process endows the support beam 11 with excellent durability; its dense resin matrix effectively resists chemical corrosion from acids, alkalis, salt spray, etc., requiring almost no maintenance and significantly extending its service life in harsh environments. The continuous and efficient pultrusion process enables the one-time molding of complex cross-sections, ensuring stable product quality and dimensional accuracy.

[0034] In one embodiment, the fastener 121 is a resin part formed by resin injection molding, which facilitates the formation of the fastener 121 and the first connector 122 as an integral part.

The limiting portion 1222 is connected to the outer peripheral surface of the connector 1221, and there are multiple limiting portions 1222 spaced apart circumferentially along the connector 1221. The second connector 13 is inserted into the connector 1221 and threadedly connected to it.

[0036] The end of the limiting part 1222 away from the connector 1221 is bent away from the axis of the connector 1221, which can improve the tightness of the connection between the first connector 122 and the fixing part 121 and prevent the first connector 122 from coming out of the fixing part 121.

In the third direction, the sub-cavities located at the top and bottom of the support beam 11 are mounting cavities 111. In the third direction, the sub-cavity located in the middle of the support beam 11 is a connecting cavity.

[0048] refer to Figure 2 The base 1 also includes connecting rods 15.
