Multiple groups of steel bar trusses 6 are arranged on the upper surface of the steel plate 1.

[0022] As a preferred embodiment, as shown in Figure 1 , Figure 5 , Figure 6 and Figure 7 The steel bar truss 6 includes steel bar main ribs 601 and web bar continuous ribs 602. The upper and lower steel bar main ribs 601 are fixedly connected into a whole through the web bar continuous ribs 602. The lower end of the web bar continuous ribs 602 is set as a horizontally bent V-shaped structure, and the horizontally bent V-shaped structure is distributed on the left and right of the vertical plane formed by the upper and lower steel bar main ribs 601. The horizontally bent V-shaped structure is fixedly connected to the upper surface of the steel plate 1 through a U-shaped buckle 7. Through the structural setting of the steel bar truss 6, not only the overall steel structure usage of the truss structure is small and the manufacturing cost is low, but also the structure is stable and not easy to deform. The U-shaped buckle 7 includes ear plates 701 and an arc connecting portion 702. The contact portion between the U-shaped buckle 7 and the horizontally bent V-shaped structure of the web bar continuous ribs 602 is set as the arc connecting portion 702, and ear plates 701 are arranged at both ends. The ear plates 701 are connected to the installation threaded holes 105 through screws, and the horizontally bent V-shaped structure of the web bar continuous ribs 602 is locked through the arc connecting portion 702 of the U-shaped buckle 7 to achieve surface contact locking, with good locking effect and small installation displacement tolerance.
