SUPERSTRUCTURE RIG MAT OF COLD-FORMED STEEL

摘要

The superstructure rig mat of cold-formed steel consists of a surface steel plate (1) with V-shaped longitudinal ribs (11) along the length of plate (1); multi-U-shaped beams manufactured from cold-formed steel by bending / stamping and welded to the underside of surface plate (1) along the length of the surface plate (1); lateral support bars (3) designed perpendicularly to the U-shaped beams (2); two inclined plain steel plates (5) and (6) are welded at both ends of the mat; the two side steel plates of the rig mat (7) in the parallelogram shapas welded to the respective edges of surface plate (1), bottom plate (4) and inclined plates (5) and (6) forming a out-box of the rig mat; and an inter-locking system (8) mounted on the plates (5) and (6).
