A reinforcing plate is installed inside the trapezoidal groove. Transverse plates for fixing the reinforcing plate are installed at the front and rear end faces of the side beam.

[0007] Preferably, a T-shaped groove is opened on the opposite side of the side beam. A T-shaped plate fixed to one end of the fixing plate is installed inside the T-shaped groove. At equal intervals at the opposite ends of the two T-shaped plates, there are first mounting holes penetrating the side beam.

[0008] Preferably, one end of the splicing seat is connected with a connecting plate. A connecting groove matching with the connecting plate is opened at the other end of the splicing seat. Second mounting holes penetrating the transverse plate are opened at the front and rear ends of the connecting plate.

[0009] Preferably, one end of the fixing plate at the first end facing the splicing seat is provided with a slotted groove for cooperating with the connecting plate, and one end of the fixing plate at the last end facing the splicing seat is connected with a connecting plate for cooperating with the connecting groove.

[0010] Preferably, top grooves are formed on the front and rear end faces of the top of the reinforcing plate, and pressing plates for cooperating with the top grooves are equidistantly installed at the top of one ends of the two cross plates facing each other.

[0011] Preferably, the reinforcing plate and the pressing plate are both made of aluminum alloy material, and the splicing seat and the cross plate are made of steel material.
