Abstract: Bridge with prefabricated sections and with external prestressing by cables A bridge has prefabricated sections and is prestressed externally of the concrete of the sections by cables. Each section has upper and lower decks, interbraced by longitudinal oblique webs which form dihedrons. Certain dihedrons are closed by transverse panels. The panels assure the desired deviations of the prestressing cables as well as their anchoring.

Abstract: A concrete structure including a rigid three-dimensional lattice of concrete bars which are interconnected at nodes. The lattice is constituted by an assembly of prefabricated cast blocks, in which each block comprises a node and a plurality of arms (14) radiating from the node. Each arm has at least one longitudinal socket with an opening in the free end of the arm, and the arms of two blocks are assembled in aligned end-to end pairs to constitute the bars of the lattice. The sockets of assembled arms are in alignment and contain a common metal reinforcing member, and the junction zone of the arms is surrounded by a clamping sleeve, with the sockets being filled with hardened mortar. The lattice is prestressed by prestress cavles passing outside the bars of the lattice and fixed to some nodes of the lattice.

Abstract: A ballastable concrete base for an offshore platform is essentially constituted by a volume formed by a three-dimensional lattice of concrete bars interconnected at concrete nodes. Some of the nodes are interconnected by prestress cables passing outside the bars and optionally past intermediate nodes. The cables three-dimensionally prestress the lattice as a whole, and the base further includes means for making watertight the side and the bottom of the lattice.

Abstract: A prefabricated three-dimensional truss structure for a bridge, or the like, the truss formed from bars arranged to define triangular or rectangular patterns. The bars are formed from prestressed, high-strength concrete that are connected at their ends with assembly blocks that are prestressed, the prestress being preferably provided by the cables that prestress the bars, and which terminate at the blocks. A plurality of such unit trusses can be assembled to provide a truss structure for a bridge span, and the trusses can assume a wide variety of configurations.

Abstract: This invention relates to a production of a structure by means of segments. The segments comprise series of prefabricated mixed steel-concrete segments(VM), each comprising a metal frame of steel integral with an upper concrete slab, these series being separated by interposed concrete segments (VB), the assembly of the segments being reinforced longitudinally by prestressed cables which penetrate the metal frames and are attached at their ends to the concrete segments. This invention may be applied to bridge floors and similar structures.

Abstract: The invention relates to the embodiment variants of the structure according to the main patent. Some of the triangles of the truss are replaced by thin concrete slabs. The figure shows a current segment of a bridge structure in which the truss triangles located in the two lateral oblique planes of the truss are replaced by thin slabs 7', 14'. Application to any structure comprising two parallel planes connected by a truss, particularly to bridge structures.
