ABSTRACT:
A structural element for a building or like structure comprising a panel member; said panel member including first and second, parallel, external faces and having at least one pair of parallel opposing sides, said panel member having an edge portion extending along each of said opposing sides, each of said edge portions being adapted in use to interconnect with an adjacent structural element; a first one of said edge portions comprising first and second flange members extending longitudinally along one side of said panel member, said first and second flange members being spaced to define between them a first recess which extends longitudinally along said one side of the panel member; and the second one of said edge portions comprising third and fourth flange members extending longitudinally along the opposing side of said panel member, said third and fourth flange members being spaced to define between them a second recess which extends longitudinally along said opposing side of the panel member; said first flange member being disposed outwardly of the plane of one of said external faces of the panel member to increase the structural strength of the element, said second flange member being adapted in use to be received within the second recess of a first identical structural element adjacent to said first edge portion of the panel member and said third flange member being adapted in use to be received within the first recess of a second identical structural element adjacent to said second edge portion of the panel member so that in use said first and second external faces of said panel member are coplanar with the first and second external faces respectively of the panel members of said adjacent identical structural elements.
