[0031] The steel beam 2 is connected to the concrete bottom plate 1. The steel beam 2 is under tension and can provide bending resistance, while the concrete bottom plate 1 is under compression and can provide compressive resistance. The two work together to form a combined structure with high bearing capacity. While saving steel, they jointly improve the bearing capacity and stability of the container bottom plate structure, effectively extending its service life. It is widely applicable to various logistics and transportation scenarios with high load and high strength requirements.

[0032] The concrete material in the concrete floor 1 has high compressive strength and bending stiffness, which can effectively disperse and withstand the pressure load in the container. In addition, the concrete floor 1 also has good durability and waterproof and fireproof properties, which can effectively protect the goods inside the container from interference from the external environment.

The spacing between the steel beams 2 can be moderately increased compared to the traditional design scheme, and can be selected within the range of 1-2.5m according to the actual thickness of the concrete base plate 1. In this embodiment, the actual number and actual setting position of the steel beams 2 can be flexibly designed according to actual use requirements to meet the bending resistance requirements of the container.

[0035] As an optional implementation, the concrete base slab 1 includes a truss floor decking slab 11 and auxiliary steel bars 12. The truss floor decking slab 11 is the main structure of the concrete base slab 1, and the auxiliary steel bars 12 are auxiliary structures, which are arranged at required positions to play a role of local reinforcement. The auxiliary steel bars 12 are connected to the truss floor decking slab 11, and after the truss floor decking slab 11 is connected to the auxiliary steel bars 12, a complete concrete base slab 1 can be formed by pouring concrete.

[0036] As an optional implementation, the truss floor deck 11 includes an upper chord steel bar 111, a lower chord steel bar 112, a web steel bar 113 and a bottom formwork steel plate 114, the bottom of the web steel bar 113 is connected to the top of the bottom formwork steel plate 114, the upper chord steel bar 111 is connected to the top of the web steel bar 113, the lower chord steel bar 112 is connected to the middle and lower part of the web steel bar 113, the upper chord steel bar 111, the lower chord steel bar 112, the web steel bar 113 and the bottom formwork steel plate 114 cooperate with each other, which can effectively improve the structural strength of the truss floor deck 11.

[0037] As an optional implementation, the auxiliary steel bars 12 include upper connecting steel bars 121 and lower connecting steel bars 122. The upper connecting steel bars 121 are arranged in parallel with the upper chord steel bars 111 and a binding overlap is formed therebetween. The lower connecting steel bars 122 are arranged in parallel with the lower chord steel bars 112 and a binding overlap is formed therebetween. The upper connecting steel bars 121 and the lower connecting steel bars 122 are arranged at positions that need to be strengthened, thereby further improving the overall structural strength of the concrete base plate 1.

[0038] As an optional implementation, the auxiliary steel bars 12 also include structural steel bars 123, which are vertically arranged and tied to overlap the upper chord steel bars 111 and / or the lower chord steel bars 112. The structural steel bars 123 are arranged at positions that need to be strengthened, and cooperate with the upper connecting steel bars 121 and the lower connecting steel bars 122 to further improve the overall structural strength of the concrete base plate 1.

The H-shaped steel is an economical and efficient profile with a more optimized cross-sectional area distribution and a more reasonable strength-to-weight ratio. Since the various parts of the H-shaped steel are arranged at right angles, the H-shaped steel has the advantages of strong bending resistance in all directions, simple construction, cost savings and light structural weight. By selecting H-shaped steel as the steel beam 2, the H-shaped steel has sufficient bending resistance and can cooperate with the compression-resistant concrete bottom plate 1.
