MEJORAS INTRODUCIDAS EN UN CARRO DE AVANCE PROGRESIVO PARA LA COSNTRUCCION DE PUENTES OBJETO DE LA INVENCION IMPROVEMENTS INTRODUCED IN A PROGRESSIVE PROGRESS CART FOR BRIDGE COSNTRUCTION OBJECT OF THE INVENTION
La presente invención, según se expresa en el enunciado de esta memoria descriptiva, se refiere a unas mejoras introducidas en un carro de avance progresivo para la construcción de puentes, destinadas dichas mejoras fundamentalmente para asegurar la integridad de los operarios, frente a los aunque poco habituales si muy graves accidentes que se producen y que en la mayoría de los casos generan, incluso víctimas mortales, teniendo en cuenta la altura a la que trabajan. The present invention, as expressed in the statement of this specification, refers to improvements introduced in a progressive carriage for the construction of bridges, such improvements intended primarily to ensure the integrity of the operators, compared to the few usual if very serious accidents that occur and that in most cases generate, even fatalities, taking into account the height at which they work.
Las mejoras también están encaminadas a asegurar la estabilidad y posición totalmente estática de unos paneles de encofrado frente a fuertes rachas de viento, destacándose también otras mejoras para evitar movimientos indeseados del conjunto del carro de avance progresivo. The improvements are also aimed at ensuring the stability and totally static position of some formwork panels against strong wind gusts, also highlighting other improvements to avoid unwanted movements of the progressive carriage assembly.
Los carros actuales de avance progresivo para la construcción de puentes incorporan medios de amarre posterior a los raíles de guiado por los cuales se desplazan los carros en su avance hasta alcanzar la posición prevista. The current progressive carriages for the construction of bridges incorporate means of mooring after the guide rails through which the cars move in their advance until reaching the planned position.
Estos amarres se encargan de mantener estables las dos cerchas laterales y su viga horizontal trasera, de manera que el carro quede asegurado contra eventuales vuelcos o cabeceos. No obstante, en la práctica, estos amarres podrían ser la causa de accidentes si por cualquier circunstancia no efectuaran adecuadamente su labor o se rompieran las barras verticales de amarre ante una fuerza puntual. These moorings are responsible for keeping the two side trusses and their horizontal rear beam stable, so that the car is secured against possible overturns or headings. However, in practice, these moorings could be the cause of accidents if for any reason they did not perform their work properly or the vertical tie bars were broken before a specific force.
Con el fin de alcanzar los objetivos y evitar los inconvenientes mencionados en los apartados anteriores, la invención propone unas mejoras introducidas en un carro de In order to achieve the objectives and avoid the inconveniences mentioned in the previous sections, the invention proposes improvements introduced in a carriage of
avance progresivo para construcción de puentes, el cual comprende en principio una robusta estructura portante formada por dos cerchas laterales unidas mediante una viga transversal posterior, otra central y al menos una celosía anterior, complementándose la estructura portante citada con otros tirantes y elementos de refuerzo conocidos. A su vez, las cerchas laterales incorporan entre sus elementos unas vigas longitudinales también, así como unos pilares centrados. progressive advance for bridge construction, which in principle comprises a robust supporting structure formed by two lateral trusses joined by a rear transverse beam, another central one and at least one front lattice, complementing the mentioned supporting structure with other known braces and reinforcement elements . In turn, the side trusses incorporate longitudinal beams as well, as well as centered pillars.
El conjunto de la estructura portante apoya y se acopla en un par de raíles paralelos de guiado que se fijan a la parte del puente construida mediante unas bridas laterales y otros elementos de fijación. The whole of the supporting structure supports and engages in a pair of parallel guide rails that are fixed to the part of the bridge constructed by means of lateral flanges and other fasteners.
Partiendo de esta premisa, las mejoras comprenden un dispositivo de amarre posterior adicional del carro de avance progresivo, caracterizándose porque cuenta con unos soportes de amarre inferior fijados a la parte del forjado realizada del puente en construcción, soportes de amarre inferior dispuestos por encima de los raíles paralelos de guiado presionando sobre los mismos, solidarizándose a dichos soportes de amarre adicionales unas porciones terminales posteriores de las cerchas laterales por mediación de pares de barras roscadas traseras y respectivas tuercas y arandelas. Based on this premise, the improvements include an additional rear mooring device of the progressive feed car, characterized in that it has lower mooring brackets fixed to the part of the floor made of the bridge under construction, lower mooring brackets arranged above the Parallel guide rails by pressing on them, joining said additional mooring brackets some rear end portions of the side trusses by means of pairs of rear threaded bars and respective nuts and washers.
Estos pares de barras traseras se encuentran dispuestas por detrás de la viga transversal posterior, These pairs of rear bars are arranged behind the rear transverse beam,
