Abstract
A prefabricated steel bridge or viaduct structure, which is formed essentially of three blocks fabricated and pre-assembled in factory, and assembled together to the construction site. Once the blocks mounted thereon the concrete pillars, a surface drain for evacuating water is installed thereof to be casted therein a concrete slab and after covered from asphalt with drip slope.

- U.S. Pat. No. 4,587,684 issued in 1986 to Miller.
- In accordance with the teachings of the present invention, there is disclosed a steel bridge or viaduct structure which is installed to the construction site in eight hours as opposed to the months-long construction periods typically associated with cast-in-place concrete bridge. The steel bridge or viaduct provides an improved structure formed essentially of three blocks fabricated and pre-assembled in factory, and after carried to the construction site. Once the blocks mounted thereon the concrete pillars, a surface drain for evacuating water is installed thereof to be casted therein a concrete slab and after covered from asphalt with drip slope. The foregoing and other objects, features, and advantages of this invention will become more readily apparent from the following detailed description of a preferred embodiment with reference to the accompanying drawings, wherein the preferred embodiment of the invention is shown and described, by way of examples. As will be realized, the invention is capable of other and different embodiments, and its several details are capable of modifications in various obvious respects, all without departing from the invention.
- Accordingly, the drawings and description are to be regarded as illustrative in nature, and not as restrictive.
- The accompanying drawings show illustrative embodiment of the present invention from which the features and advantages will be readily apparent.
-
FIG. 1 is an elevation view of the prefabricated bridge incorporating the principles of the invention. -
FIG. 2 is a view showing a block of the bridge structure. -
FIG. 3 is a view showing two blocks of the bridge structure. -
FIG. 4 is an isometric view of the prefabricated bridge incorporating the principles of the invention. -
FIG. 5 is a cut view of the prefabricated bridge incorporating the principles of the invention. -
FIG. 6 is a view showing the three blocks disassembled. -
FIG. 7 is an enlarged view of the prefabricated bridge incorporating the principles of the invention. - According to the embodiment of the present invention, as depicted in
FIGS. 1 to 7 , it is shown the steel bridge or viaduct structure which is formed essentially of three blocks fabricated and pre-assembled in factory, and assembled together to the construction site by means of joints (4) and bolts (11). Each block is formed of diaphragms (3) assembled to angle iron (14) welded to beams (8,9) sliding on pieces (7) fixed thereon the concrete pillars (6). The beams (8) are welded to parapet (5) assembled to guardrail (1). Once the blocks mounted thereon the concrete pillars (6), a surface drain (10) for evacuating water is installed thereof to be casted therein a concrete slab (2) and after covered from asphalt (12) with drip slope (13). - Each block weighs approximately sixty tons and is five feet height, three feet width, and a hundred fifteen feet length. For the two-track roads it is necessary to install several blocks in the middle so as to obtain the desired width.
- This new concept would particularly advantageous in the construction on-site of mega interchange which is be very complicated and extremely dangerous for the safety of workers on the construction site and the drivers circulating on the roads.
- Although only a single embodiment of the present invention has been described and illustrated, the present invention is not limited to the features of this embodiment, but includes all variations and modifications within the scope of claims.
