The technical scheme has the advantages that: because each reinforcing rib and the first fixing lugs on the two sides of each reinforcing rib are formed by bending the same strip-shaped steel plate, and each reinforcing rib is bent to form a long groove arranged along the length direction of the reinforcing rib, the strength of the reinforcing rib is improved, the weight of the reinforcing rib is lighter, and the cost is saved; the notches of the long grooves of the longitudinally arranged reinforcing ribs and the notches of the long grooves of the transversely arranged reinforcing ribs are respectively arranged towards two opposite directions, so that the stability of the supporting net is improved, and the longitudinally arranged reinforcing ribs and the transversely arranged reinforcing ribs are conveniently connected and fixed through respective first fixing lugs.
As a further improvement of the invention, the slotted hole is formed by bending the base plate after being cut at the corresponding position, and the support plate is formed by bending the cut part.
The technical scheme has the advantages that: the structure is more reasonable, and the processing of the bottom plate and the supporting plate is convenient; the backup pad is cut by the bottom plate and is buckled formation, with bottom plate integrated into one piece, so need not additionally increase bearing structure, alleviateed the whole weight of bearing plate, the transportation of the spare part of being convenient for simultaneously.
As a further improvement of the invention, the supporting plates at least have one inclined edge formed by cutting the bottom plate, and the inclined edge of each pair of supporting plates is bent towards the inner side direction of the two supporting plates to form a reinforcing edge.
The technical scheme has the advantages that: because the supporting plates are formed by cutting and bending the bottom plate, the inclined edges of each pair of supporting plates are bent towards the inner side directions of the two supporting plates to form reinforcing edges, the strength of the supporting plates is improved, the supporting plates are prevented from deforming, and therefore each pair of reinforcing ribs connected with the supporting plates can be better supported.
