  • Patent number: 4084916
    Abstract: A steel mesh system for reinforcing concrete for airport landing strips and the like, comprising at least two mesh sections, each including separate groups of spaced apart parallel steel bars positioned perpendicularly to each other and welded together at their intersection, placed side by side, and rigid brackets securing peripheral aligned rods at adjacent sides of the mesh sections together. Each bracket is substantially U-shaped defining a recess to receive the peripheral rods and includes two leg portions separated by a connecting portion. One of the leg portions of each bracket is undercut so that the opening of the recess is of smaller extent than the bottom of the recess. A set screw having a convex end extends through the free end of the other leg of the U-shaped member outwardly of the recess with respect to the center of the parallel bars positioned within the recess.
