Two inclined supports 1-2 are arranged on the bottom plate 1-1 in parallel, and the two inclined supports 1-2 are connected through a transverse plate 1-4. Specifically, the transverse plate 1-4 connects and fixes the two inclined supports 1-2 in the same supporting unit 1, so that the two inclined supports 1-2 are matched to form two supporting points which are distributed at intervals in the length direction of the I-beam 4, and the stability of the I-beam is improved.

The floor panel 1-1 is configured to include an outer panel portion 1-1a and an inner panel portion 1-1b, the inner panel portion 1-1b being located on a side close to the i-beam 4, and the outer panel portion 1-1a being used to connect the earth bolt 1-3 to the lower panel portion 1-2b. A lateral adjusting member 1-5 is provided between the outer plate portion 1-1a and the inner plate portion 1-1b for adjusting the distance between the outer plate portion 1-1a and the inner plate portion 1-1 b.

Specifically, the lateral adjustment member 1-5 includes a lateral adjustment screw 1-5a and a lateral adjustment screw 1-5b that are screw-engaged with each other. One end of a transverse adjusting screw sleeve 1-5a is rotatably arranged on the outer plate body, and one end of a transverse adjusting screw rod 1-5b is fixed on the inner plate part 1-1 b. The transverse adjusting screw rods 1-5b are axially displaced by rotating the transverse adjusting screw sleeves 1-5a, so that the inner plate portions 1-1b are displaced between the outer plate portions 1-1a and the transverse section of the bottom of the I-beam 4, and further, after the outer plate body is fixed to the ground purlin 3 through the ground bolts 1-3, the inner plate portions 1-1b can be abutted against the side faces of the transverse section of the bottom of the I-beam 4 by adjusting the inner plate portions 1-1b, so that the I-beam 4 is limited by the inner plate portions 1-1b, and the fixing effect of the I-beam 4 is improved.
