  • Patent number: 6112480
    Abstract: A stairway 2 is fabricated using a plurality of load bearing modules 4 that are attached to form a box beam 60 that can be freestanding. Each module 4 included flat vertical front and rear panels 6, 20 that are joined by vertical inside and outside panels 30, 38. The modules are joined by affixing the front panel of a higher module to the rear panel of the next adjacent lower module to form a stepped configuration. For a curved stairway 2, the helical box beam 60 formed of a plurality of trapezoid shaped modules 4 provides the principle support for the weight of the stairway 2 and the weight of any body positioned on the stairway. Longitudinal members 64, 66, 68 extending between the lower edges of adjacent modules 4 are loaded in tension and resist separation of the individual modules 4. Because the box beam 60 is the primary weight carrying member, the longitudinal members can be relatively thin and flexible and easy to fabricate.

  • Patent number: 6082063
    Abstract: An anchorage for a tendon that includes a sleeve having a smooth tapered interior bore and a compressible wedge disposed in the sleeve. The compressible wedge has a smooth exterior tapered surface tapering from a wider end to a narrower end and one or more interior channels for receiving a tendon. The taper angle of the compressible wedge is greater than the taper angle of the bore. Thus, upon insertion of the compressible wedge into the sleeve, the wider end of the compressible wedge forms a wedge contact with the sleeve before the narrower end forms a wedge contact with the sleeve. Preferably, the bore and wedge are conical, and the wedge is formed of several symmetrical pie shaped resilient sections. Corners of the sections abutting at the interior channel are rounded. An inner sleeve is disposed in the interior channel, with the outer diameter of the inner sleeve matching the diameter of the interior channel. The tendon is held by the inner sleeve.
