  • Structural sandwich plate members
    Publication number: 20090031655
    Abstract: A structural sandwich plate member is provided with at least one stud welded to one or both of the outer plates and extending into the core. The stud may be arc stud welded to the outer plate before formation of the core. Alternatively, the stud may be installed after formation of the core by drilling a hole in one outer plate and friction welding the stud to one or both outer plates.

  • Method of reinforcing a bridge
    Publication number: 20090013482
    Abstract: A method of repairing, reinforcing or reinstating a bridge, comprising fixing a reinforcing plate in a spaced relationship with an existing plate or girder, especially on the underside of the bridge structure, to form a closed cavity, and injecting plastics or polymer material into said cavity in liquid form, whereby said plastics or polymer material sets or cures so as to bond to said reinforcing and existing plates with sufficient strength to transfer shear forces therebetween.

  • Structural Sandwich Plate Members
    Publication number: 20080127594
    Abstract: A structural sandwich plate member is manufactured by adhering perimeter bars to the faceplates rather than by welding. This method enables the production of plate members with reduced distortion. Alternatively a sealant strip may be used between the perimeter frame and the faceplates.

  • Double hulls
    Patent number: 7337736
    Abstract: Barge double hull sections wherein at least part of the double hull is comprised of first and second layers and an intermediate layer of elastomer material bonded to the first and second layers. By manufacturing double hull walls of such three layered structures, the stiffness of the hull as compared to hulls of the prior art can be significantly increased, thereby decreasing the amount of separate stiffeners required in the hull structure.

  • Bridge deck panels, fabrication methods and use
    Patent number: 7207079
    Abstract: Bridges decks or panels for bridge decks made of a metal-plastic-metal sandwich with the plastic bonded to the metal plates so as to transfer shear forces therebetween. The sandwich plates may be constructed with either a solid plastic core or a composite core consisting of plastic, metal plates or structural shapes and forms within or without a frame of girders. Sandwich plate bridge panels without peripheral metal frames are held together only by the adhesion of the plastic to the metal plates.
