Abstract

UN TRATAMIENTO FINAL (110) DE UN SISTEMA DE SEGURIDAD DE BARANDAS QUE COMPRENDE: - UNA PORCIÓN TERMINAL DE UNA VIGA (102) DE BARANDA COMPRENDIENDO UNA VIGA W QUE TIENE UN EXTREMO HACIA ABAJO Y UN EXTREMO HACIA ARRIBA, LA PORCIÓN TERMINAL DE LA VIGA (102) DE BARANDA INCLINADA DESDE UNA PRIMERA ALTURA VERTICAL APROPIADA PARA REDIRECCIONAR UN VEHICULO ERRANTE A UNA SEGUNDA ALTURA VERTICAL PRÓXIMA A LA SUPERFICIE DEL SUELO EN EL EXTREMO HACIA ARRIBA DE LA PORCIÓN TERMINAL DE LA VIGA DE BARANDA, DONDE EL EXTREMO HACIA ARRIBA COMPRENDE UNA VIGA W APLANADA QUE ES ASEGURADA PRÓXIMA A LA SUPERFICIE DEL SUELO; - UNA PORCIÓN PLANA (112) FORMANDO UN CANAL A TRAVÉS DEL CUAL LA PORCIÓN TERMINAL DE LA VIGA (102) DE BARANDA ES DISPUESTO, UNA DIMENSIÓN VERTICAL DEL CANAL QUE ES MAYOR EN UN EXTREMO HACIA ABAJO DE LA PORCIÓN PLANA (112) QUE EL EXTREMO HACIA ARRIBA DE LA PORCIÓN PLANA (112); Y - UNA PLACA (114) DE IMPACTO ACOPLADA A LA PORCIÓN PLANA (112), LA PLACA DE IMPACTO (114) PARA ENGRANAR UN VEHICULO QUE IMPACTA EN UN EXTREMO DE DICHA VIGA (102) DE BARANDA; Y - DONDE EL EXTREMO HACIA ARRIBA ES APLANADO PREVIO A UN IMPACTO FINAL Y DONDE LA PLACA DE IMPACTO (114) Y LA PORCIÓN PLANA (112) AVANZAN LONGITUDINALMENTE A LO LARGO DE LA VIGA (102) DE BARANDA EN UN DIRECCIÓN HACIA ABAJO POR UN VEHICULO DURANTE EL IMPACTO FINAL, EL AVANCE DE LA PLACA (114) DE IMPACTO Y LA PORCIÓN PLANA (112) DISIPANDO ENERGIA PARA DESACELERAR AL VEHICULO QUE IMPACTA Y APLANANDO LA VIGA (102) DE BARANDA VERTICALMENTE EN TANTO LAS PORCIONES HACIA ABAJO DE LA VIGA (102) DE BARANDA SON FORZADAS A LA PORCIÓN PLANA (112).A FINAL TREATMENT (110) OF A SAFETY SYSTEM OF RAILINGS INCLUDING: - A TERMINAL PORTION OF A BEAM (102) OF RAILING INCLUDING A BEAM W THAT HAS AN END DOWN AND AN END UPWARD, THE TERMINAL PORTION OF THE BEAM (102) OF RAILING INCLINED FROM A FIRST VERTICAL HEIGHT SUITABLE TO REDIRECT A Wandering VEHICLE TO A SECOND VERTICAL HEIGHT NEAR THE GROUND SURFACE AT THE UPWARD END OF THE TERMINAL PORTION OF THE RAILING BEAM, WHICH EXPANDS A RAILING BEAM FLAT W-BEAM THAT IS SECURED CLOSE TO THE GROUND SURFACE; - A FLAT PORTION (112) FORMING A CHANNEL THROUGH WHICH THE TERMINAL PORTION OF THE RAILING BEAM (102) IS ARRANGED, A VERTICAL DIMENSION OF THE CHANNEL THAT IS GREATER AT A DOWNWARD END OF THE FLAT PORTION (112) THAN THE UPWARD END OF FLAT PORTION (112); AND - AN IMPACT PLATE (114) COUPLED TO THE FLAT PORTION (112), THE IMPACT PLATE (114) TO ENGAGE A VEHICLE THAT IMPACTS AN END OF SAID RAILING BEAM (102); AND - WHERE THE UPWARD END IS FLATTED PRIOR TO A FINAL IMPACT AND WHERE THE IMPACT PLATE (114) AND THE FLAT PORTION (112) ADVANCE LONGITUDINALLY ALONG THE RAILING BEAM (102) IN A DOWNWARD DIRECTION VEHICLE DURING THE FINAL IMPACT, THE ADVANCE OF THE IMPACT PLATE (114) AND THE FLAT PORTION (112) DISSIPATING ENERGY TO DECELERATE THE IMPACTING VEHICLE AND FLATING THE RAILING BEAM (102) VERTICALLY IN BOTH THE PORTIONS DOWN THE BEAM (102) OF RAILINGS ARE FORCED TO THE FLAT PORTION (112).
