Erected platform

An erected platform wherein the platform is erected by the steps of:

• providing an existing platform portion which has decking laid on existing parallel quad-chord trusses wherein a first of the existing parallel quad-chord trusses has an end and a second of the existing parallel quad-chord trusses has an end, wherein an edge of the decking extends between and is adjacent the end of the first existing parallel quad-chord truss and the end of the second existing parallel quad-chord truss, wherein the first existing parallel quad-chord truss includes a first side including two chords each having at least one first aperture adjacent the end of the first existing parallel quad-chord truss and further includes a second side including two chords each having at least one second aperture adjacent the end of the first existing parallel quad-chord truss, wherein the second existing parallel quad-chord truss includes a first side including two chords each having at least one first aperture adjacent the end of the second existing parallel quad-chord truss and further including a second side including two chords each having at least one second aperture adjacent the end of the second existing parallel quad-chord truss;
• positioning a first other quad-chord truss generally parallel to and generally adjacent the edge of the decking so that ends of the first other quad-chord truss are generally adjacent the ends respectively of the first and second existing parallel quad-chord trusses, wherein the first other quad-chord truss includes a first side including two chords each having at least one first aperture adjacent one of the ends of the first other quad-chord truss and further includes a second side including two chords each having at least one second aperture adjacent the one of the ends of the first other quad-chord truss;
• aligning the first apertures in the first other quad-chord truss with the first apertures in the first existing parallel quad-chord truss thereby providing aligned first apertures;
• inserting a first pin in the aligned first apertures;
• swinging the first other quad-chord truss about the first pin to a position wherein the first other quad-chord truss is in generally an end-to-end relation and co-axial with the first existing parallel quad-chord truss;
• aligning the second apertures in the first other quad-chord truss with the second apertures in the first existing parallel quad-chord truss thereby providing aligned second apertures;
• inserting a second pin in the aligned second apertures whereby the first other quad-chord truss is rigidly attached end-to-end to and co-axial with the first existing parallel quad-chord truss;
• removing the first pin from the aligned first apertures;
• swinging the first other quad-chord truss about the second pin to a position wherein the first other quad-chord truss extends in a direction away from the second existing parallel quad-chord truss;
• positioning a second other quad-chord truss generally parallel to and generally adjacent the edge of the decking, wherein the second other quad-chord truss includes a first side including two chords each having at least one first aperture adjacent an end of the second other quad-chord truss and further including a second side including two chords each having at least one second aperture adjacent the end of the second other quad-chord truss;
• aligning the first apertures in the second other quad-chord truss with the first apertures in the second existing parallel quad-chord truss thereby providing aligned first apertures of the second other quad-chord truss and the second existing parallel quad-chord truss;
• inserting a third pin in the aligned first apertures of the second other quad-chord truss and the second existing parallel quad-chord truss;
• swinging the second other quad-chord truss about the third pin to a position wherein the second other quad-chord truss is in generally an end-to-end relation and co-axial with the second existing parallel quad-chord truss;
• aligning the second apertures in the second other quad-chord truss with the second apertures in the second existing parallel quad-chord truss thereby providing aligned second apertures of the second other quad-chord truss and the second existing parallel quad-chord truss;
• inserting a fourth pin in the aligned second apertures of the second other quad-chord truss and the second existing parallel quad-chord truss whereby the second other quad-chord truss is rigidly attached end-to-end to and co-axial with the second existing parallel quad-chord truss;
• swinging the first other quad-chord truss about the second pin to a position wherein the first other quad-chord truss is in generally an end-to-end relation with and co-axial with the first existing parallel quad-chord truss;
• again aligning the first apertures in the first other quad-chord truss with the first apertures in the first existing parallel quad-chord truss thereby again providing aligned first apertures of the first other quad-chord truss and the first existing parallel quad-chord truss;
• and
• again inserting the first pin in the aligned first apertures of the first other quad-chord truss and the first existing parallel quad-chord truss whereby the first other quad-chord truss is again rigidly attached end-to-end to and co-axial with the first existing parallel quad-chord truss.
