The invention relates to a truss 10 for a cage of a structural building panel. The truss 10 comprises elongate first and second support members 12, 14 defining longitudinal edge portions 16 of the truss 10, and a connecting element 18 which extends between the longitudinal edge portions 16 and which interconnects the first and second support members 12, 14. The first and second support members 12, 14 are adjacent to and in spaced parallel or substantially parallel relationship with each other. The invention also relates to the structural building panel 50a, 50b itself. The structural building panel 50a, 50b incorporates at least two said trusses 10, at least one insulation member 52 sandwiched between adjacent trusses 10, and at least one retaining member 56 for retaining the insulation member 52 in position. The structural building panel 50a, 50b offers increased strength and rigidity over existing prefabricated building panels for the same dimensions and materials. An extended truss 100a, 100b and extended structural building panel 150a, 150b can be formed by connecting a pair of trusses or panels end to end. The truss can have three or four parallel elongate members, all in the same plane with the additional elongate members being positioned intermediate the first and second elongate support members. |
