2. The floor panel of claim 1, wherein: The floor beam (300) comprises a horizontally arranged base plate (10), left and right wing plates (11) and (12) located on both sides of the base plate (10), the first connecting piece (21) of each connecting piece group is connected with the left wing plate (11) of the floor beam (300), and the second connecting piece (22) is connected with the right wing plate (12) of the floor beam (300).

3. The floor panel of claim 2, wherein: The left wing plate (11) and the right wing plate (12) are provided with first extension plates (13) and second extension plates (14) on the sides away from each other, and the lower surfaces of the horizontally arranged first extension plates (13) and the second extension plates (14) are respectively overlapped with the upper surface of the support plate (6).

4. The floor panel of claim 3, wherein: The first extension plate (13) and the second extension plate (14) each further comprise a first horizontal part (15) connected to the upper end of the left wing plate (11) or the right wing plate (12), a second horizontal part (16) located on the side away from the left wing plate (11) or the right wing plate (12) of the first horizontal part (15) and higher than the first horizontal part (15), and a vertical part (17) connecting the other end of the first horizontal part (15) and one end of the second horizontal part (16).

5. The floor panel of claim 4, wherein: Further comprising a plurality of support plates (18) corresponding to the floor beams (300), each support plate (18) is correspondingly installed between the two vertical parts (17) on one floor beam (300) and the lower surfaces of the two ends of the support plate (18) are overlapped with the upper surfaces of the two first horizontal parts (15), and the upper surface of the support plate (18) is flush with the upper surface of the second horizontal part (16).
