Abstract
Abstract A truss-beam swimming pool includes slightly bowed truss beams 52 and 53 secured together at their ends by joints 70 and forming a self-restraining rectangle. The beams take lateral thrust from tops of posts 28, which support continuous sidewalls 26 which support sidewalls 24 of a plastic pool member 20. The joints 70 rest on corner posts 30 and tie together inner chords 46 and end webs 60 of the beam. The joints also support the inner ends of corner beam members 78. The beams are supported by posts 28, 30 and 43 and have duckboards nailed to the chords thereof to form a deck. The lower ends of the posts are secured together by tierods and by bottom frame members 41.
