Abstract
A bridging structure of modular elements to carry road or rail traffic over crossings, bodies of water and as elevated roadways to provide additional lanes over and parallel to existing roads and freeways, and to provide elevated roadways along and over canals and rivers. Mainly intended to provide quickly assembled and relative inexpensive overpasses and constant flow traffic lanes for a certain part of the traffic, leaving more space for heavier traffic at the existing ground levels, and reducing pollution and fuel consumption from idling engines.
Claims11
A bridge structure of modular elements comprising:
- a. a plurality of spaced bases each formed with an upper opening for the insertion of a colum;
- b. a plurality of columns formed inserted in each said opening an with horizontal flutings dimensioned for the insertion of cores between said flutings and complementary flutings in the an other components to be fastened to said columns and serving as variable positioning means for horizontal beams
- c. a shetled position beam on said column also provided with said complementary flutings and cores as securing means to said column and to road carrying elements
- d. said road forming elements being provided with fluted means positioning and securing said element on said beams and on foundations provided with complementary securing means.
