Patent number: 4665830Abstract: A vehicle supporting guideway is presented, the guideway is comprised of upper horizontal stringers, lower horizontal stringers vertically oriented diagonal members affixed to the upper and lower horizontal stringers and horizontally oriented diagonal members are affixed between the lower horizontal stringers. These features present a guideway having an upwardly extending U-shape construction which can be supplied with wheel supporting channels, and upper support channels. The entire structure is reinforced by ribs which are generally within the horizontal stringers, and the entire guideway may be enclosed by a cover. Overlapping members join adjacent sections of the horizontal stringers together.Type: GrantFiled: June 7, 1985Date of Patent: May 19, 1987Assignee: Regents of the University of MinnesotaInventors: J. Edward Anderson, Donald C. Sassor

Patent number: 4615063Abstract: An anchoring rod extends vertically through a hollow box girder underlying a suspension bridge or suspended walkway. The anchoring rod is connected at its upper end to a suspension cable and is provided at its lower end with a stop member which can be tightened against the lower wall of the girder. The opening in the lower wall of the girder through which the anchoring rod extends is larger than the opening in the upper wall of the girder, and a tubular, load-bearing sleeve is carried on the anchoring rod through the lower wall opening. The tubular sleeve is sized so that the upper end abuts against the inner surface of the upper wall of the girder and the lower end abuts against the stop member when the stop member is tightened against the lower wall of the girder.Type: GrantFiled: November 13, 1984Date of Patent: October 7, 1986Inventor: Carl R. Rolen

Patent number: 4589157Abstract: This invention relates to a production of a structure by means of arch stones. The arch stones comprise series of mixed steel-concrete arch stones (V.sub.M), each comprising a metal frame of steel integral with an upper concrete slab, these series being separated by interposed concrete arch stones or sections, (V.sub.B), the assembly of the arch stones being reinforced longitudinally by prestress cables which penetrate the metal frames and are attached at their ends to the concrete arch stones. This invention may be applied to bridge floors and similar structures.Type: GrantFiled: February 5, 1985Date of Patent: May 20, 1986Assignee: BouyguesInventor: Pierre Richard

Patent number: 4489659Abstract: A girder for supporting a movable body has a truss structure of a cross-sectional shape forming an isosceles triangle with a horizontal base. The truss structure is formed of three main tubes of a circular cross section that are located in positions corresponding to respective corners of the triangle and extend continuously over the length of the girder. A plurality of branch tubes of circular cross section are fixed at their ends to respective pairs of the main tubes by joint pieces, such that three branch tubes lie in a plane extending through the respective joint pieces perpendicular to the longitudinal axes of the main tubes so as to form the isosceles triangle. A rail support is secured to each main tube of the base of the isosceles triangle at a position disposed upwardly and outwardly of the center thereof, and a rail, along which the movable body is traversable, is supported on each rail support.Type: GrantFiled: October 9, 1981Date of Patent: December 25, 1984Assignee: Hitachi, Ltd.Inventors: Hideaki Kamohara, Minoru Imamura, Hiroshi Higaki, Yuji Yoshitomi, Syuzo Uno, Kazuhiro Makino, Hiroshi Nomura, Kyozo Yoshioka
