Patent number: 8850750Abstract: A rapidly-erectable lightweight load resisting system for the construction of buried arched bridges, tunnels or underground bunkers, has a plurality of lightweight arched tubular support members which are formed of a fiber reinforced polymer material and are substantially oriented in a vertical plane. The lightweight tubular support members are connected by at least one or more lateral force resisting members which are positioned in a direction perpendicular to the vertical plane of the tubular support members, and which are capable of transferring vertical loads to the tubular support members and of providing lateral-load capacity to the load resisting system. The tubular support members are fitted with one or more holes near the top which allows them to be filled with a suitable material to provide additional strength or stiffness.Type: GrantFiled: January 26, 2005Date of Patent: October 7, 2014Assignee: University of Maine System Board of TrusteesInventors: Habib J.

Patent number: 5361554Abstract: A suspended deck system uses prefabricated deck block modules as the working surface. Each block comprises a series of lateral beam bars in closely spaced, mutually parallel relation, having their ends secured by tie members splined in place. In one embodiment the deck blocks are of square plan-form, having wooden beam bars of substantially square section, with eased edges, having their ends tied by a thin, elongated wood spline. The block thickness and the length of the beam bars are selected to ensure the necessary bending strength when simply suspended by their ends in a loaded condition, as part of a suspended platform. In the case of a wooden decking the deck blocks are supported upon a framing of joists and cross-braces having rabetted upper edge recesses into which the deck blocks fit in flush-fitting relation. The blocks may be positioned in an alternating pattern, giving a visual parquet effect.Type: GrantFiled: November 6, 1992Date of Patent: November 8, 1994Inventor: Robert Bryan

Patent number: 5338499Abstract: A method for the fabrication of a composite structure made from a profile plate and concrete. The relatively lightweight steel profile plate is placed at the building site. At the building site the concrete is sprayed on the surface of the profile plate to form the composite structure. The profile plate can be sprayed with concrete, layer by layer, with each layer being allowed to at least partially set between sprayings. Thus, the inherent load-bearing capacity of the structure increases as the layers are applied and the weight of the structure increases.Type: GrantFiled: September 16, 1993Date of Patent: August 16, 1994Assignee: Gerestek OyInventor: Seppo I.

Patent number: 4490950Abstract: The front wall of an overfilled reinforced concrete arch is built from two prefabricated reinforced concrete elements, that are connected in the center by an on-site cast joint, which transmit the vertical loads acting upon them only to the foundation of the underpass, while the horizontal loads, brought about by the earth pressure from the overfill, are transmitted only at the outer edges to the wing wall and to the arch foundation, on one hand, and on the other hand to the arch from the apex portion. In the apex portion, these forces are transmitted from the front wall to the arch by means of metal rods, that transmit only horizontal stresses.Type: GrantFiled: December 3, 1981Date of Patent: January 1, 1985Inventor: Werner Heierli

Patent number: 4480348Abstract: A tension-band bridge having one or more main openings (2) and possibly subsidiary openings (3), comprises a tension band (4) gripped between abutments (5) and possibly taken over supporting pillars (6). The traffic route over the bridge is disposed on a saddling (7), which bends in the longitudinal direction of the bridge, in the region of the main openings (2), while the tension band (4) can be travelled over directly in the region of any subsidiary openings (3) which may be present. The saddling which bends in the longitudinal direction of the bridge preferably consists of a latticework construction (10, 11, 12) which is rigid in the transverse direction of the tension band (4) and which is connected, in the longitudinal direction of the bridge, by means of diagonal struts (13) in each of which shock absorbers (14) are disposed.Type: GrantFiled: March 22, 1983Date of Patent: November 6, 1984Inventor: Ulrich Finsterwalder

Patent number: 4458457Abstract: An arch is formed of prefabricated reinforced concrete shells connected at the arch apex by an on-site cast concrete joint is built as a skewed underpass structure. In order to avoid complicated edge elements or a costly lengthening of the underpass, the individual reinforced concrete shells are formed to have their horizontal projection (in the horizontal projection of an assembled underpass) define a parallelogram which includes at least one acute angle which correspond to the acute angle formed by the intersection of the axis of the overpass traffic route with the axis of the underpass traffic route. Thus, edge elements are not necessary. An apex joint is formed of on-site cast concrete. Reinforcement rods extend into the apex joint and are arranged in an asymmetrical manner so that all elements can be designed and reinforced in the same manner with the reinforcement rods in the joint meeting directly.Type: GrantFiled: December 3, 1981Date of Patent: July 10, 1984Inventor: Werner Heierli

Patent number: 4192120Abstract: In a method of constructing a reinforced concrete bridge a supporting arch s erected which comprises a cocked center part of which forms a supporting reinforcement intended to be incorporated in the concrete of the final bridge structure. Shuttering is placed in position on the arch and the concrete poured to embody the supporting reinforcement and constitute the deck of the bridge. The resultant deck is formed by a ribbed slab, by girders connected by a slab, or by at least one box. After the concrete has hardened the remaining exterior part of the arch is removed, and if required additional reinforcement may be embodied in the concrete.Type: GrantFiled: December 12, 1977Date of Patent: March 11, 1980Assignee: Entreprises de Travaux Publics et Prives J.
