Abstract

"TERMINAIS APERFEIçOADOS PARA TRILHOS DE SEGURANçA". Dispositivos e métodos para sustentar instalações de terminais de trilhos de segurança que incorporam tratamentos seguros das extremidades, tais como o GHT e o SRT. Concretizações preferidas são descritas em que as instalações de terminais são presas, principalmente, ao solo, usando colunas de sustentação fracas, que são feitas, de preferência, de metal. As extremidades da instalação de trilho de segurança são presas ao solo usando colunas de desprendimento. Em operação, as colunas fracas permitem que a porção central da instalação de trilho de segurança contenha e redirecione o veículo durante uma colisão lateral com o elemento de trilho. A fixação proporcionada pelas colunas extremas de desprendimento ajuda a impedir o trilho de segurança de ser excessivamente deslocado, assim, impedindo o veículo que bate de se despedaçar através do trilho de segurança. Em operação, os conjuntos de terminais de trilho de segurança construídos de acordo com a presente invenção proporcionam um sistema de sustentação aperfeiçoado para o elemento de trilho, o qual é melhor do que as fixações de colunas fortes convencionais, assim, proporcionando um aperfeiçoamento na segurança.
