Patent number: 4648147Abstract: A tension tie member is anchored between two spaced locations on a structure, such as a diagonal cable in a stayed girder bridge. The tie member is supported on the structure adjacent at least one anchor location by an annular bearing member encircling an outer protective casing of the tie member. The bearing member is positioned within an annular chamber in the structure at the point where the tie member extends through the structure toward the anchor location. The diameter of the annular chamber is larger than the diameter of the tie member so that there is a certain amount of play between the bearing member encircling the tie member and the surface of the annular chamber whereby lateral movement of the tie member can occur. With the tie member anchored in place the space between the outside of the bearing member and the inside surface of the annular chamber can be filled with grout to support the tie member.Type: GrantFiled: April 30, 1985Date of Patent: March 10, 1987Inventors: Egbert Zimmermann, Oswald Nutzel

Patent number: 4648146Abstract: In the assembly of a tension tie member between spaced anchors when the tie member is made up of a number of individual tension elements, such as steel wires, steel strands or the like, enclosed within a tubular sheathing, the tension elements are inserted individually and successively between the anchors and it is necessary to insert the annular wedges which anchor each element before the tension elements are released from a threading device. To prevent the annular wedges from prematurely entering into the boreholes in the anchor plate, an auxiliary plate is positioned spaced from the anchor plate. The auxiliary plate has at least one through borehole axially alignable with the boreholes in the anchor plate. A tubular section is secured to the auxiliary plate and forms an extension of the borehole therein. An annular wedge to be inserted into one of the boreholes and the anchor plate can be held on the tubular section by resiliently expanding the wedge about the outer surface of the tubular section.Type: GrantFiled: April 30, 1985Date of Patent: March 10, 1987Assignee: Dyckerhoff & Widmann AktiengesellschaftInventors: Oswald Nutzel, Egbert Zimmermann

Patent number: 4633540Abstract: A tie member includes at least one tension element, such as a steel wire or strand, enclosed within a tubular sheathing. An anchoring unit is located at each end of the tie member for transmitting the tension force to a part of a structure. Each anchoring unit includes an anchor plate with at least one conically shaped bore so that a tension element can be secured in the borehole by a multi-part annular wedge. To provide additional corrosion protection and improve fatigue strength in the anchorage, the tension element is enclosed within a coating of a synthetic resin for its entire length. The inside surface of the wedge is shaped between the ends with a series of coarse or rough teeth with the tips rounded off.Type: GrantFiled: April 30, 1985Date of Patent: January 6, 1987Assignee: Dyckerhoff & Widmann AktiengesellschaftInventors: Dieter Jungwirth, Gerd Thielen, Otmar Langwadt

Patent number: 4473915Abstract: In an anchored tension member individual elements, such as steel rods or the like, extend between a pair of anchoring discs each of which is secured on a support. One support is spaced horizontally and vertically from the other so that the tension member extends at an acute angle to the horizontal. In assembling and installing the tension member, first one individual element is placed through a tubular casing resting on the support of a support structure which incorporates one of the supports. Next, the individual element is tensioned between and anchored to the anchoring discs. During this operation, the tubular casing is lifted off the surface and extends rectilinearly between and is spaced from both of the anchoring discs. In turn, the remaining individual elements are placed through the tubular casing, tensioned and then anchored to the anchoring discs. As a result, the tension member can be installed in position without additional auxiliary apparatus, such as lifting devices and scaffolds.Type: GrantFiled: September 24, 1982Date of Patent: October 2, 1984Assignee: Dyckerhoff & Widmann AktiengesellschaftInventor: Klemens Finsterwalder

Patent number: 4264996Abstract: A suspended railway has a track hung via a plurality of hangers from a suspension cable which is supported at intervals at the tops of towers. A beam is provided at each of these towers which bows the track when unloaded downwardly at the tower. A saddle is furthermore provided at the top of each of the towers and has an upwardly open seat receiving and supporting the suspension cable. This seat has a length measured parallel to the length of the beam which is equal to at least one-third of the length of the beam. Furthermore the seat has a central portion with a larger radius of curvature than its flanking end portions. The saddle is carried on rollers for rolling in a horizontal direction parallel to the suspension cables, and can even twist about a vertical axis perpendicular to this horizontal axis.Type: GrantFiled: November 1, 1978Date of Patent: May 5, 1981Inventors: Rudolf Baltensperger, Hans B.

Patent number: 4211171Abstract: A suspended railway has a fixed tower spaced horizontally from a fixed station. A suspension cable is slung between this tower and the station and a plurality of horizontally spaced upright hangers depending from this cable support a suspended section of a horizontally extending track also having a fixed section secured in the station. As a car travels along the track it vertically deflects the track from an upper unloaded position to a lower loaded position. A substantially rigid guide beam projects from the station between the track and the cable toward the tower and has a lower guide surface bearing downwardly on the track in the unloaded position thereof. Thus as the car approaches the fixed section of the track at the station the suspended section is pulled downwardly away from the guide beam.Type: GrantFiled: November 1, 1978Date of Patent: July 8, 1980Inventors: Rudolf Baltensperger, Hans B.
