What is claimed is: 1. A fabric covered rigid frame structure comprising: at least three elongate rafters, each having an axis; at least one column supporting each of the at least three elongate rafters; a fabric cover covering the at least three elongate rafters; a web system comprising a plurality of separate web strips, separate from the fabric cover, hemmed into edges of the fabric cover; and at least one tensioner formed in an end of at least one elongate rafter, wherein the tensioner comprises: an opening formed in an end of the at least one elongate rafter, wherein the opening is formed along the axis of the at least one elongate rafter; a first fitting disposed between the opening and an end of the at least one elongate rafter, wherein the first fitting is connected to the at least one elongate rafter; a rod disposed in the at least one elongate rafter along the axis of the at least one elongate rafter through the first fitting, wherein the rod comprises threads that are exposed to at least a portion of the opening; means for engaging the rod through the first fitting; and a cylindrical sliding block disposed within the at least one elongate rafter, wherein the cylindrical sliding block has an outer diameter substantially similar to an inner diameter of the elongate rafter, and wherein the cylindrical sliding block has a longitudinal threaded aperture for receiving the threaded rod and engaging the threads of the rod, and wherein a hook is attached to the cylindrical sliding block and the hook extends through the opening directly engaging the web strips and the fabric cover, and tensioning the fabric cover. 2. The structure of claim 1, wherein the sliding block with the hook is an at least one piece structure. 3. The structure of claim 1, wherein the hook is connected to the sliding block at an angle from 0 degrees to 180 degrees from the axis of the at least one elongate rafter. 4. The structure of claim 1, further comprising a biasing means disposed between the means for engaging the rod and the rod to prevent the rod from releasing tension. 5. The structure of claim 1, further comprising a second fitting disposed inside the at least one elongate rafter on a side of the opening opposite the first fitting, and wherein the second fitting is adapted for receiving the rod and the second fitting is secured to the at least one elongate rafter. 6. The structure of claim 5, wherein the first fitting and the second fitting are connected to the at least one elongate rafter by a connecting means, and wherein the connecting means comprises at least one bolt, at least one screw, welding, adhesive, or combinations thereof. 7. The structure of claim 1, wherein the web system further comprises a web extension disposed at the end of each web strip for further tensioning the fabric cover to the hook. 8. The structure of claim 1, wherein the at least one column is anchored to a foundation, earth, or another structure. 9. The structure of claim 1, wherein at least two elongate rafters connect to at least one rigid beam and each of the at least two elongate rafters engages opposite sides of a support beam. 10. A fabric covered rigid frame structure comprising: at least three elongate rafters, each elongate rafter having an axis; at least one column supporting each of the at least three elongate rafters; a fabric cover covering the at least three elongate rafters; a cord system comprising a cord hemmed into edges of the fabric cover; and at least one tensioner formed in an end of the at least one elongate rafter, wherein the at least one tensioner comprises: an opening formed in an end of the at least one elongate rafter, wherein the opening is formed along the axis of the at least one elongate rafter; a first fitting disposed between the opening and an end of the at least one elongate rafter, wherein the fitting is securely connected to the at least one elongate rafter; a rod disposed in the at least one elongate rafter along the axis of the at least one elongate rafter through the first fitting, wherein the rod comprises threads that are exposed to at least a portion of the opening; means for engaging the rod through the first fitting; and a cylindrical sliding block disposed within the at least one elongate rafter, wherein the cylindrical sliding block has an outer diameter substantially similar to an inner diameter of the elongate rafter, and wherein the cylindrical sliding block has a longitudinal threaded aperture for receiving the threaded rod and engaging the threads of the rod, and wherein a hook is attached to the cylindrical sliding block and a hook extends through the opening directly engaging the cord and the fabric cover and tensioning the fabric cover. 11. The structure of claim 10, wherein the cord comprises a wire, a cable, a chain, a hemp cord, a cotton rope, a nylon rope, a synthetic polymer rope, or combinations thereof. 12. The structure of claim 10, wherein the sliding block with the hook is an at least one piece structure. 13. The structure of claim 10, wherein the hook is connected to the sliding block at an angle from 0 degrees to 180 degrees from the axis of the at least one elongate rafter. 14. The structure of claim 10, further comprising a biasing means disposed between the means for engaging the rod and the rod to prevent the rod from releasing tension. 15. The structure of claim 10, further comprising a second fitting disposed inside the at least one elongate rafter on a side of the opening opposite the first fitting, and wherein the second fitting is adapted for receiving the rod and the second fitting is secured to the at least one elongate rafter. 16. The structure of claim 15, wherein the first fitting and the second fitting are connected to the at least one elongate rafter by a connecting means, and wherein the connecting means comprises at least one bolt, at least one screw, welding, adhesive, or combinations thereof. 17. The structure of claim 10, wherein the at least one column is anchored to a foundation, earth, or another structure. 18. The structure of claim 10, wherein at least two elongate rafters connect to at least one rigid beam and each of the at least two elongate rafters engages opposite sides of a support beam.
