All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

It will be understood that when an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in the description of the present application herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

As shown in fig. 2 to 4, in one embodiment, a composite car platform is disclosed, and the composite car platform of the embodiment includes a car bottom plate 1 and side frames 2 mounted on the car bottom plate 1, wherein the thickness of the car bottom plate 1 is 1.5mm, and the car bottom plate 1 includes a flat plate which is located at the bottom and has a square plate surface shape. Among four sides of the flat board, wherein two relative sides upwards buckle and form hem 11, the side frame 2 is two that install on the flat board and relative arrangement, and each side frame 2 is arranged side by side and is leaned on each other with the hem 11 of corresponding side.

The car bottom plate 1 is also provided with a plurality of composite beams 5 connected between the two side frames 2, the composite beams 5 are of a composite filling structure, and the composite filling structure comprises an outer frame 51 with a closed circumferential direction and a composite material layer 52 filled in the outer frame 51.

The composite car bottom of the embodiment adopts the steel plate with the thickness of 1.5mm, and the thickness of 3-5 mm in the prior art is replaced, so that the material cost is greatly saved.

And adopt composite beam 5 to consolidate the sedan-chair bottom plate in this embodiment, composite beam 5 is because the structure for inside filling combined material, so the cutting of being convenient for draws materials as required, avoids drawing materials extravagantly. In one embodiment, the composite layer 52 is a slag layer or a concrete layer, which makes full use of building materials and avoids waste.

In addition, the opposite side edges of the car bottom plate 1 in the embodiment are bent upwards to form the folded edges 11, and the folded edges 11 enable the side edges of the car bottom plate 1 to keep good straightness and flatness of the platform surface, and meanwhile strength of the car bottom plate 1 is also enhanced.

In order to further improve the strength of the car bottom plate 1, in an embodiment, of four side edges of the flat plate, two side edges which are bent upwards to form the folding edges 11 are first side edges, and the other two side edges are second side edges; one of the second side edges is bent upwards and then folded inwards to form an inverted L-shaped side plate 12, and a car side plate reinforcing rib 6 is connected between the side plate 12 and the flat plate.

The connection of the composite cross beams 5 provides one-way reinforcement for the car bottom plate, and in order to reinforce the car bottom plate in multiple directions, in one embodiment, a cross beam reinforcing rib 7 is connected between every two adjacent composite cross beams 5. And the crossbeam strengthening rib 7 is the steel sheet of 2mm thick, when guaranteeing the reinforcement effect, material saving.
