Web core structural panel
First Claim
1. A structural panel comprising:
- first and second metal skins each presenting exterior and interior panel surfaces, a web core of metal construction between said first and second skins in engagement with said interior surfaces thereof to maintain the skins in a spaced relationship, including a plurality of spaced-apart, elongated primary members having longitudinally spaced connectors extending therefrom and further having transversely aligned, longitudinally spaced slots therein, said web core further including a plurality of spaced-apart cross members each having spaced slots therein receiving said primary members at corresponding transversely aligned slots thereof to provide an interlocked grid between said first and second skins, at least certain of said connectors including a pair of spaced projections, and said skins having openings therein receiving corresponding projections, and welds at said projections securing said web core to the respective skins to provide a rigid panel structure.

Abstract
A panel system includes a first skin, a second skin, a web core constructed from sheet material for securing the skins together in a spaced, sandwich relationship, and a connecting means for affixing the web core within the skins. The web core includes a plurality of spaced apart longitudinal members having longitudinally spaced projections extending therefrom and further having transversely aligned, longitudinally spaced slots therein. The web core further includes a plurality of spaced-apart, transverse cross members each having spaced slots therein receiving the longitudinal members at corresponding transversely aligned slots thereof to provide an interlocked grid between the first and second skins. The grid is connected to the skins utilizing the projections, which extend through slits in the skins to facilitate welding or otherwise bonding the components.

9. A method of forming a structural panel, comprising the steps of:
-
(a) providing a first skin, a second skin and a web core including a plurality of primary grid members and cross grid members, all composed of a metal, (b) mounting the cross grid members in a spaced relationship on the primary grid members to present an interlocked grid, including mating slots formed in the primary grid members with slots formed in the cross grid members, and (c) affixing the first and second skins on opposed sides of the grid, including providing spaced-apart pairs of spaced projections that extend from at least certain of said grid members and welding the projections to the skins. - View Dependent Claims (10, 11)
