| 181 | COMPOSITE RCC DECK AND PRESTRESSED PARABOLIC BOTTOM CHORD UNDERSLUNG OPEN WEB STEEL GIRDER BRIDGE SUPERSTRUCTURE | US18271410 | 2022-03-06 | US20240060253A1 | 2024-02-22 | Pramod Kumar SINGH |
| Composite decks increase bridge strength and stiffness. Prestressed composite open web steel girder has added advantage of high strength cable support. Results of typical 125 m span bridges having heights of 9.0 m, 10.0 m and 12.5 m, and another 50.0 m span and 2.5 m height are given. Member stresses and bridge deflections during erection remained safe. Average steel off take for the 125 m bridge is 2.65 t/m and for the 50 m span bridge it is 1.77 t/m for limiting live load deflection of Span/800. Its reserve strength is 3.2 times service condition live load. The girders are panel wise workshop fabricated, assembled at site, jacked up or crane lifted to secure over bearings. Connection of the cross members, and onsite deck casting in parts with stage wise bottom chord prestressing is carried out. Short to long span bridges for single or multiple lanes in road, rail, metro rail, and coastal link projects are feasible. | ||||||

| The bridge construction system and method according to the present invention provides a lightweight, efficient, economical, long-lasting, and easily implemented composite steel structure that can be filled with concrete in place for the construction of pedestrian and smaller road bridges, specifically those found in rural areas. The bridge construction system of the present invention is unique in that it is a steel-frame reinforced composite bridge with decking and rebar caging that provides a permanent, non-removable form for poured-in-place concrete. The composite nature of the bridge allows for installation of the bridge to take place in one day, while the entire process from site preparation such as grading and excavation to cleanup takes a week or less. The quick installation of the bridge is designed to have a minimally invasive impact on the surrounding environment. | ||||||
| 198 | PREFABRICATED CONCRETE PIER TOP FORM | US17069592 | 2020-10-13 | US20220112671A1 | 2022-04-14 | Chad William Cerwin |
| A single-use or multi-use prefabricated pier top form for topping a concrete pier comprises a hollow mold with an upper portion in the desired shape of the finished pier top, a stepped-down tapered mid portion, and a lower mating portion for mating with the pier form so that concrete can be continuously poured to fill both the pier form and the pier top form at one time. Use of the prefabricated pier top form results in substantial time and material savings because the top of the pier residing above ground can be formed at the same time as the footer and pier are formed replacing the need to form a separate pier top after the pier and footer have been filled with concrete. | ||||||
