accuspacer-prefabricated multi structural timber alignment fixture

Abstract

Prefabricated Multi Structural Timber Alignment Fixture, for quicker & cheaper roof structural timber' installation, comprises L beam ( 1 ) having four welded U channels ( 3 ) matching standard roof timber width, embodying holes ( 7 ) to nail timber to channels ( 3 ). USES & ADVANTAGES: 1. Saves time, labour & costs on repetitive roof truss accurate fixing & installation. 2. Inexpensive instant accurate permanent and safe truss alignments in one go. 3. Eliminates need for temporary alignment templates & battens, requiring removal. 4. Eliminates need for measuring tapes and associated operative errors. 5. Assembly at ground level 4 trusses & 3 accuspacers, using only hammer & nails. 6. Entire accuspaced assembly of 4 trusses can be hoisted high and safely into position. 7. Versatile Alignment Fixture can be deployed for horizontal and sloping trusses. 8. Fabricated beam construction substantially enhances building structural soundness.
