ABSTRACT:The invention relates to a system for launching a structure, comprising: a first deck produced and mounted by means of the successive addition of voussoirs and designed to be longitudinally moved up to stacks by means of at least one pushing system; and a second deck placed on the upper part of the first deck, or lower deck, and securely connected to said lower deck by means of dismountable connecting means. The second deck, or upper deck, is designed to be the last span of the structure and, when securely fixed to the lower deck, is designed to be pushed over the stacks together with the lower deck. The connection means are designed to transmit the force from the lower deck to the upper deck, in such a way that the two decks work together in a joint manner, collaborating in order to resist the overall shear, flexion and torsion forces that are produced during the launching. The invention also relates to a method for launching a structure by pushing.
RESUMEN:Un sistema de lanzamiento de una estructura, que comprende: un primer tablero fabricado y montado mediante la adición sucesiva de dovelas y configurado para desplazarse longitudinalmente hacia unas pilas mediante uno o varios sistemas de empuje; y un segundo tablero colocado sobre la parte superior del primer tablero o tablero inferior, y unido solidariamente al inferior mediante medios de unión desmontables. El segundo tablero o tablero superior está diseñado para ser el último vano de la estructura y, al estar unido solidariamente al inferior, está configurado para ser empujado sobre las pilas conjuntamente con el tablero inferior. Los medios de unión están configurados para transmitir el esfuerzo desde el tablero inferior al superior, de forma que ambos trabajan de forma solidaria colaborando para resistir los esfuerzos globales de cortante, flexión y torsión que se producen durante el lanzamiento. Un método de lanzamiento de una estructura mediante empuje.
