Abstract

Perfeccionamientos introducidos en un tramo de escalera cuya construcción de soporte rígida a la flexión, que presenta el menos un larguero, esta formada por barras de soporte yuxtapuestas, eventualmente unidas entre sí de forma soltable y dirigidas alternándose en sentido vertical y en sentido horizontal, viniendo determinada a la altura de contrahuella por la distancia vertical entre dos barras de soporte horizontales contiguas, previstas como apoyo para las placas de huella, y viniendo determinada la profundidad de huella por la distancia horizontal entre dos barras de soporte verticales contiguas, caracterizados porque la distancia horizontal entre las barras de soportes verticales es menor que la profundidad de huella deseada, y las barras de soporte horizontales presentan por el lado frontal unos brazos volados que sobresalen de las barras de soporte verticales que originan su apuntalamiento y que sirven para el apuntalamiento frontal de las placas de huella, cuyas profundidades determinantes de la superficie de apoyo del pie están reducidas alternativamente por un lado a aproximadamente la medida de la distancia horizontal entre las dos barras de soporte verticales contiguas.
