A method of forming structural sandwich plate members involves connecting perimeter bars using at least one stud welded to one of the outer plates. The stud(s) may be arc stud welded to the outer plate through an aperture in the perimeter bar.
Claims10
A method of manufacturing a structural sandwich plate member, comprising the steps of:
- providing a first metal plate,
- providing at least one perimeter bar, having at least one through-hole, in contact with said first metal plate so that a stud or studs fixed to said first metal plate projects into said through-hole(s);
- fixing said perimeter bar to said stud(s);
- fixing a second metal plate to said perimeter bar so that the second metal plate is spaced from the first metal plate to form a cavity bounded by said first and second metal plates and said perimeter bar;
- filling said cavity with uncured plastics or polymer material;
- and
- allowing said plastics or polymer material to cure to bond said outer plates together with sufficient strength to transfer shear forces there between.
A structural sandwich plate member comprising first and second outer metal plates and a core of plastics or polymer material bonded to said metal plates with sufficient strength to transfer shear forces therebetween, the member further comprising a bar fixed to said first metal plate via a stud projecting from the first metal plate.
